Description

Technical Field

[0002] In the field of heavy equipment manufacturing, large hydraulic presses are key production equipment. The accuracy of their multi-cylinder synchronous control directly affects the workpiece forming quality and equipment operation stability. Traditional multi-cylinder synchronous structures generally use synchronous valves to distribute oil to achieve coordinated action of each cylinder.

[0003] However, in actual working conditions, the dynamic load and mechanical vibration generated when the hydraulic press is working can easily cause the threaded connection between the synchronous valve and the oil distribution pipe to loosen. This loosening will not only damage the oil circuit sealing and delivery, causing uneven oil distribution, but also directly affect the synchronous action of each cylinder.

[0004] Therefore, how to achieve vibration resistance and anti-loosening of the connection structure between the synchronizing valve and the oil distribution pipe has become an urgent technical problem to be solved. Utility Model Content
