How to choose the most suitable shrinking machine

The buyer may find that the zinc layer is easy to fall off and scratch the mold base and cylinder block with zinc foam after using it for a short time after purchasing the pipe shrinking machine, and even damage the core parts. What should I do when I encounter this problem? How to choose a high-quality pipe shrinking machine? If your buckle press is not a new one, you will find that there is no resin sponge between the mold base of your buckle press. Who wants to replace it all the time with a shrinkage machine? How to maintain their service life? How to avoid this phenomenon?

working principle:
Driven by the motor, the oil pump outputs hydraulic oil to push the plunger in the buckle cylinder forward, so that the plunger and the two inner conical sleeves on the front cylinder head push the die base with symmetrical conical surface to shrink radially, so as to realize the module to buckle the rubber hose. When the shrinkage reaches the setting value of the scale, the buckle stops automatically, the solenoid reversing valve changes back, and the hydraulic oil enters the two mold opening cylinders to push the buckle plunger to move reversely, and the die seat drives the module to recover under the action of spring.
Working process: the fastening mechanism is the working mechanism of the locking machine. Driven by the cylinder piston, the pressing sleeve realizes reciprocating movement, and continuously compresses and relaxes the spring pressure head fixed on the front plate. Put the assembled joint into the appropriate position in the middle round hole of the spring pressure head, start the motor to drive the oil pump to supply oil, control the electromagnetic reversing valve to change direction, drive the oil cylinder piston to move forward, and press the spring pressure head with the same taper through the pressure sleeve with inner taper hole, so as to achieve the purpose of pressing. Press the mold opening button, the piston drives the pressing sleeve to move in the opposite direction, and the spring pressure head recovers. At this time, the hose joint can be taken out from the pipe locking machine.

Features of pipe shrinking machine:
(1) The upper part is provided with a holding part for stacking embryo tubes, and the front part is provided with a channel to guide the embryo tubes one by one to the front and fall to the bottom;
(2) A pushing device is arranged at the bottom of the blanking groove, which is provided with a receiving mechanism to receive the embryo tubes falling from the chute one by one, and a pushing feeding mechanism;
(3) The feeding device is provided with a movable claw cylinder which moves the embryo tube from the feeding position to the working position;
(4) The clamping device is provided with a clamping claw cylinder for clamping and positioning the embryo tube at the working position;
(5) The pushing positioning device is provided with a positioning die which can push forward and retreat at one end of the embryo tube;
(6) The double rotating shaft forging device is provided with a body which can advance and retreat, in which a roller group is arranged in a ring, and a rotatable mold holder is arranged on the inner side of the roller group, the mold holder is provided with a radial groove, two guide blocks are parallel arranged on both sides of the groove, and two separate moulds are arranged between the two guide blocks, and the outer side of the mold is provided with a roller group In addition, the center rotating shaft column can be set in two mold cavities, and then combined with the structure mentioned above, a new practical heat conduction pipe shrinking machine is formed.
