Hydraulic press protection device against overload

The tonnage that the press can withstand is certain. Once it exceeds the limit, it will damage the machinery and equipment, just as each person can bear the same weight. Therefore, presses and hydraulic presses are generally designed and manufactured. Overload device to prevent excessive weight. The following Jicheng Machinery Co., Ltd. to the crank press as an example to introduce our customers:

In addition to the main components of the working mechanism, transmission system and airframe, the crank press also has some auxiliary devices. These auxiliary devices play a very important role in ensuring the process needs and the normal operation of the press, ensuring safe production and expanding the scope of equipment use. The important role.

Press overload protection The crank press load exceeds the allowable load overload. There are many causes of overload, such as improper press selection, improper mold adjustment, blank thickness, blank overlap, or debris falling into the mold cavity.

Overloading can cause damage to the press, such as damage to the connecting rod thread, bending of the screw, bending, twisting or breaking of the crankshaft, deformation or cracking of the fuselage, and the crank press is a machine that is relatively prone to overload.

To prevent overloading, various overload protection devices have been developed. In general, large-scale presses adopt hydraulic pressure protection devices, and medium and small-sized presses use oil pressure or pressure collapse protection devices.
