After compressing the sheet to a specified thickness, it is necessary to maintain the sheet for a period of time to stabilize its deformation. In traditional designs, the load during the stabilization process is completely borne by the hydraulic cylinder, which causes the sealing components inside the hydraulic cylinder to be in a high-load state for a long time, which will affect the sealing life.

Driven by the hydraulic cylinder, the pressure beam slides linearly up and down along the vertical arm, at the lower end of the pressure beam a pressure plate for cold pressing the sheet material is fixed, and in the vertical arm a vertical stabilizing guide rod is also fixed, and in both ends of the pressure beam magnetic locking devices are fixed for being sleeved on the outside of the stabilizing guide rod, for locking the position of the pressure beam after reaching the cold pressing position, thereby reducing the sealing pressure of the hydraulic cylinder.

This makes it convenient to disassemble and transport the pressure plate, and the pressure plate can be adjusted to a suitable horizontal plane by adjusting the position of the spring pressure cover, effectively avoiding skewing.

[0010] The advantages and positive effects of the utility model are as follows: the stacked plates are placed on the upper end surface of the chassis, and then the hydraulic cylinder is started to press the pressure plate downward; when the plates are compressed to a specified thickness, they need to be maintained for a period of time, at which time the electromagnet can be started through the electrical control cabinet so that it is magnetically fixed on the stable guide rod, thereby reducing the oil pressure seal load of the hydraulic cylinder, effectively improving the service life of the hydraulic cylinder and ensuring the accurate compression thickness; the transverse sliding block can be tightly attached to the stable guide rod under the action of the spring to ensure the stability and reliability of the magnetic attraction.

[0019] Preferably, an electrical control cabinet 16 matching the magnetic lock 19 is also fixedly provided on the chassis 10 for controlling the start and stop of the magnetic lock 19 .
