Description

Technical Field

[0002] The hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swinging motion). In the process of metallurgy, the foundry needs to use hydraulic cylinders to make the metallurgical equipment perform linear reciprocating motion as required.

The new type of heavy metallurgical equipment hydraulic cylinder can unload the external force through the design of the buffer pad to reduce the violent vibration inside, and through the design of the auxiliary mechanism, when the hydraulic cylinder body is hit by the outside, the first connecting block can be driven to move, the first connecting block can be driven to move the connecting plate, the connecting plate can be driven to move the connecting rod, and the connecting rod can be driven to move the second connecting block. At this time, the spring is compressed, and the auxiliary mechanism on the other side has the opposite working principle, so as to achieve the effect of reducing the force of the hydraulic cylinder body inside the protective frame.

At the same time, dust and debris in the external air are also easily attached to the surface of the telescopic rod, which is easy to cause damage to the surface of the telescopic rod during the telescopic movement.

[0004] Therefore, we proposed a heavy-duty metallurgical equipment hydraulic cylinder with full enclosure protection to solve the above problems. Utility Model Content
