Electrical stamping parts processing plant

Electrical stamping parts processing plant
The stamping parts of electrical appliances refer to the hardware used in electrical appliances. Most of the hardware parts of electrical appliance manufacturers are produced by professional stamping factories outside.
The production efficiency of electrical stamping is high, and the operation is convenient, and it is easy to realize mechanization and automation. This is because stamping depends on the stamping die and stamping equipment to complete the processing, ordinary press stroke times can reach dozens of times per minute, high-speed pressure can reach hundreds or even more than 1000 times per minute, and each stamping stroke may get a stamping part.
When stamping, as like as two peas, the stamping die is ensured by stamping die, and the die surface is generally not long. The stamping quality is stable and interchangeability is good.
Electrical stamping can process parts with large size and complex shape, such as stopwatch of clock, longitudinal beam of automobile and covering parts. In addition, the cold deformation and hardening effect of materials during stamping make the stamping strength and rigidity higher.
In general, there is no chip and broken material in electric appliance stamping, so the material consumption is less and other heating equipment is not needed. Therefore, it is a kind of material saving and energy-saving processing method, and the cost of stamping parts is low.

What should be paid attention to when making aluminum alloy stamping parts in stamping factory

Aluminum alloy stamping parts refer to the metal stamping parts made of aluminum alloy. There are many kinds of aluminum alloy materials and specifications. Different aluminum alloy materials have different performance and use.
Aluminum alloy stamping parts have good plasticity. Because pure aluminum is very soft, not strong, has good ductility, can be drawn into thin wire and rolled into foil, with good machinability, so it is widely used in wire and cable manufacturing industry, radio industry and packaging industry. The properties of some metals can be greatly improved by adding a small amount of aluminum. If a small amount of magnesium and copper are added into the aluminum alloy stamping parts, the tough aluminum alloy stamping parts can be made.


What should be paid attention to when making aluminum alloy stamping parts in stamping factory
In addition, it is more easy to scratch the aluminum alloy and iron alloy in the following aspects
1. If the number of projects is not affected, the punching should be arranged in the back engineering as far as possible. Even for the products with a large number of punching holes, one more project can be considered, and the punching should be arranged at the back.
2. The aluminum material is soft and the mold is easy to block. Therefore, 10% of the thickness of the double side material should be placed when designing the die clearance. The straight depth of the knife edge should be 2mm, and the taper should be 0.8-1 °.
3. During bending, aluminum scraps are easy to be produced during bending, which will cause spot damage and indentation. PE film should be pasted on aluminum raw materials. In case of roller and electroplating, polishing and hard chromium plating is preferred for forming blocks.
4. For the stamping parts to be processed after anode, if there are pressing and pushing processes of 180 ° and the products can not be fully pressed, and the complete pressing will produce acid spitting phenomenon. A gap of 0.2-0.3 mm should be left to facilitate the acid liquid to flow out smoothly and timely. Therefore, a limit block must be made and the mold must be calibrated higher than the mold.
5. As the aluminum material is brittle and easy to crack, especially in the case of reverse folding, try not to do the pressing line. Even if it is necessary to do it, it is necessary to make the line wider and shallower.

Production capacity of stamping parts processing

Production capacity of stamping parts processing
In the hardware stamping plant, someone once calculated the speed of the punch, and used the punch speed to calculate the production capacity of stamping parts processing. The results are quite different from the previous figures. What causes the low production capacity?
First of all, there are different types of presses and different speeds. There are high-speed presses up to 600 per minute, and pneumatic presses with 30 to 50 strokes per minute. Equipment maintenance is the premise to ensure that in the production of stamping parts processing, the production capacity will not be affected due to machine failure. What’s more, the production training of the staff, the gap between the novice and the proficient, the result is still very obvious at the end of the day.
Precision metal stamping factory production corner
After the machine personnel have no problem, it is the mold of stamping parts processing. The rationalization of the design, the precision of the processing, the rationalization of the mold installation and adjustment. After the mold is ensured to be correct, the detection of raw materials is also a key point. Most of the coiling materials commonly used in stamping plants ensure that the dimension of the strip is within the tolerance, which is convenient for the feeding and feeding of the die. Machines, personnel, molds, materials are reasonable and smooth, so according to the press speed to plan production capacity, basically is not much difference.
Stamping parts processing generally requires high accuracy, which is divided into suppliers according to this requirement, but not all stamping parts hardware factories can meet this standard
Some stamping parts processing plants are the materials used to produce common materials on the market, which are called national standard parts. There are also some non-standard parts that need to be opened according to the customer’s drawings. This requires a good design team and a good stamping die to ensure the stability of stamping parts processing.

What are the uses of metal stamping parts

What are the uses of metal stamping parts
Metal stamping parts refer to steel / non-ferrous metal and other sheet dies, which are formed to the specified shape by the pressure required for processing by the press. What are the hardware stamping parts according to the application fields? The following small series will give you a brief introduction.
1. Stamping enterprises in automobile industry. For example, wheel hub and gear are mainly deep drawing. In China, they are mainly concentrated in automobile factories, tractor factories, aircraft manufacturers and other large factories, and independent large-scale stamping and drawing plants are rare.
2. Home industry stamping enterprises. Such as aluminum window, mainly forming by punching and shearing. Many of the enterprises in this department are in the standard parts factory, and there are also some independent stamping plants, most of which are small factories.
3. Electrical industry stamping enterprises. Such as rice cooker, washing machine and other components. This kind of factory is a new industry, which develops with the development of electrical appliances. The factories in this sector are mainly concentrated in the south.
4. Household stamping enterprises. Some handicrafts, such as tableware and so on, these factories also have great development in recent years.
5. Mobile phone industry stamping enterprises. For example, card slot, fixing frame, etc. These factories were established after the development of household appliances in China, and most of them are distributed in household appliance enterprises.
6. Special stamping enterprises. For example, the stamping of aviation parts belongs to this kind of enterprise, but these process factories are also included in some large factories.

How to maintain the metal stamping die

How to maintain the metal stamping die
In the metal stamping industry, precision metal stamping die is widely used. For example, mobile phones, medical care, cars, computers, etc., how should we usually maintain them.
1: The precision of the mold is very high. When you use it, you must pay attention to that there are no impurities in the mold, because the impurities will lead to the precision of the mold.
2: Always use copper or aluminum to remove the mold during mold installation and maintenance. Because copper or aluminum is not as hard as iron, it will not make the mold swell.
3: Spray antirust oil when the mold is used up so that the mold will not rust.
Good hardware stamping factory is used to control raw materials in this way
I believe that many hardware stamping plant purchasers will be troubled, how to control the purchase of raw materials? Today let’s take you to analyze: precision metal stamping high-quality raw materials
1. The hardware stamping plant needs stable and large-scale raw material manufacturers instead of replacing them frequently. Today’s purchasing point will purchase some from tomorrow’s. Because each metal stamping plant has its own product design habits, there will be some small differences. Precision hardware stretching products
2. The qualified material report shall be provided for each incoming material of the hardware stamping plant, which shall be filed and compared. The time of each master material will be slightly different, but it will not affect the use.
3. Metal stamping factory can not change the material without notice and keep it confidential

Metal stamping products need innovation

Metal stamping products need innovation
In the fierce market competition, the metal stamping industry has suffered a variety of tests brought by the market. The homogenization of products makes the overall depression of the metal stamping Market. In this case, the enterprise must survive in the change, meet the market demand, product innovation test enterprise, must consider the factors, then how to innovate? The following is a summary of several points, product innovation considerations.
Ruishuo – company meeting
First of all, we need to find out the demand of the consumer market for metal stamping parts. If the enterprise wants to really open up a new road in the difficulties, it must clarify the market demand, for the next product innovation distance, reasonable planning, market demand understanding, we can start from the needs of different age groups, different product grades and other aspects, consumers on hardware The appearance function of stamping products, as well as the special requirements of products, all of which require enterprises to keep in mind the market demand.
Ruishuo – a patent of self timer
In today’s rapid development of society, consumers are feeling the huge impact of information, if a metal stamping factory does not have a different product, it will be quietly eliminated by this era

Design of metal stamping die

Design of metal stamping die
Die making is a technical work. Because of the different uses and structures of metal stamping products, the design of dies can not be the same. How to be an excellent designer? Xiaobian has several points to share with you
1、 Recognition. For example, if you look at the world when you are young and you look at the world at 40, there will be a big difference in cognition. Hardware stamping products used in different industries, precision and requirements will also have a gap. Some simple, low precision products, you can design time about some mold costs. And some high-precision products also need to consider the cost, assembly, mass production and other factors in the early stage.
2、 Industry experience. For example, some engineers are good at the design of some precision terminals, but some precision metal stamping parts for structure will also know about the process. However, it may have unimaginable consequences for the actual situation in the later mass production and some wear conditions of the mold.
How to use and maintain the mold to prolong the service life of hardware mold?
3、 Reaction ability. In particular, some of the high requirements of metal stamping products, problems in response to the strategy. If the problem is solved immediately, if it is not handled well, it will be revised or not solved.
Attitude. It seems that there are always some people with positive energy. Love to learn, love to share, think about things, and be responsible for things. Hardware stamping design, is the same reason! I believe this kind of employees can make more breakthroughs.

Grinding details of non standard metal stamping die

Grinding details of non standard metal stamping die
There are three main types of machine tools used for grinding non-standard metal stamping dies: surface grinder, internal and external cylindrical grinder and tool grinding tool. Grinding deformation and grinding cracks should be strictly controlled during finishing grinding. Even tiny cracks will be exposed in subsequent processing. Therefore, the feed of fine grinding should be small and not large, the coolant should be sufficient, and parts with dimensional tolerance within 0.01mm should be grinded at constant temperature as far as possible.
In the process of production and manufacturing, there are two main methods to use the surface grinder to grind the parts: one is to use the formed grinding wheel after dressing, the other is to grind with special fixture.
Grinding details of non standard metal stamping die
Grinding with form grinding wheel: when dressing the grinding wheel with diamond, most of them are dressing the geometric shape of the forming surface in sections, but some of them are dressing the grinding wheel into shaping. This method of dressing grinding wheel is mainly accomplished by various grinding wheel tools. The grinding wheel tools in production mainly include grinding angle, arc grinding wheel, universal grinding wheel, profiling grinding wheel, etc.
Grinding with special fixture: when grinding the workpiece, the workpiece can be clamped on the special fixture according to certain conditions, and the required shape can be obtained by fixing or constantly changing the position during the processing. The commonly used grinding fixtures are: precision flat pliers, sinusoidal magnetic table, sinusoidal indexing fixture, universal fixture, rotating magnetic table and center hole splint. This grinding method is generally carried out on a surface grinder.

How to choose the material of metal stamping parts

How to choose the material of metal stamping parts
How to choose the material of metal stamping parts? Most of our processed metal stamping parts include red copper, brass, phosphor bronze, stainless steel, iron, aluminum, carbon steel, nickel, spring steel and other stamping materials. Some alloys with better plasticity are also a kind of metal stamping materials, but this depends on whether the customer requires this material for processing. So how should we choose the material of metal stamping parts?
1. The choice of sheet roll width: In the steel plate specifications, whether it is a fixed-length sheet or a coil, the same material and thickness of the material have different sales prices for different roll widths. Therefore, in order to reduce costs, it is necessary to work hard on the formulation of the procurement roll width, and try to select the roll width range without price increase under the premise of ensuring the utilization of materials. For example, try to choose the appropriate size for the cut-to-length board. After the shearing from the steel plant is completed, it is not necessary to perform secondary shearing to reduce the cutting cost; for the coiled board, try to choose the coil size and technology for uncoiling forming to reduce secondary Shearing workload improves work efficiency.
How to choose the material of metal stamping parts?
2. Selection of plate thickness deviation: the thickness of the plate has deviation requirements, usually within the allowable range of deviation, the plate with the lower deviation should be selected first.
3. Material and material thickness: When selecting materials for product design, avoid using high-grade materials to cause excess product performance. At the same time, under the premise of meeting product and process requirements, try to choose the material and material thickness of the existing mass-produced models , To form a material platform to facilitate subsequent procurement and inventory management.

Nidec builds new R&D base for electric vehicle motors

Nidec builds new R&D base for electric vehicle motors
According to foreign media reports, Nidec, the world’s leading producer and supplier of electric motors, will build new research and development facilities for electric vehicle drive motors in China in order to respond to the risks brought by the tensions between China and the United States and absorb local demand in China.
Nidec has invested about 100 billion yen (about 6.5 billion yuan) to build a factory in Dalian, China, and the research and development base will be located in the factory. The base will be put into operation in 2021. In addition to the research and development of drive motors for pure electric vehicles, it will also develop motors for home appliances.
The new R&D base is expected to employ 1,000 employees, which is equivalent to the company’s medium-sized R&D center in Shiga Prefecture, Japan. About 400 employees will be responsible for the development of electric vehicle motors. Densan also plans to increase the number of employees in two other existing factories in China, and increase the number of engineers specializing in electric vehicles from the current 100 to 650 within a few years.
Densan’s move comes at a time when its global competitors are also vying to expand their business in China. Continental plans to set up a research and development center in Tianjin in 2021, and another German supplier, Bosch, also cooperates with a local company to supply electric vehicle engines.
Fearing that the United States may tighten restrictions on Chinese products, Nissan will carry out its main business in China and the United States. The company has established automobile engine, industrial and home appliance engine plants in the United States. Shigenobu Nagamori, Chairman and CEO of Densan, has always been a firm advocate of cross-border expansion, and believes that more globalization and bringing the supply chain back home will only increase risks.
