Abstract

The invention relates to the technical field of press machine lubricating devices, in particular to a lubricating device for a press machine balancer piston. The lubricating device comprises a vertically-mounted balancer cylinder. An upper end cover and a lower end cover are respectively arranged at two ends of the balancer cylinder. A piston is mounted in the balancer cylinder in a sliding manner. A piston rod mounted on the piston penetrates through the lower end cover. A sealing piece is arranged between the piston rod and the lower end cover. An annular oil storage groove is reserved on the piston. An oil inlet is arranged on the upper end cover and corresponding to the annular oil storage groove. An oil leaking device is arranged between the piston and the balancer cylinder, and connected with the annular oil storage groove. A sealing device for preventing oil-leakage is arranged between the piston and the balancer cylinder. The sealing device is mounted on the piston and positioned on one side of the lower end cover. The lubricating device has the advantages of good lubricating effect, all-around automatic lubrication, high lubricating efficiency, simple operation, reliability and convenience in application.

Description

technical field [0001] The invention relates to the technical field of lubricating devices for presses, in particular to a lubricating device for a piston of a press balancer. Background technique [0002] Traditional presses are generally equipped with a balancer that balances the weight of the slider and the mold. The balancer can prevent the impact and wear of the transmission system of the press when the slider falls due to its own weight, and it can also prevent the failure of the brake or the connecting rod. When broken, the slider will fall and cause accidents, so it is one of the important components in the use of the press. The reliability of the balancer is related to the safety performance of the whole press; [0003] The balancer generally adopts a structure in which the piston is slidingly installed in the cylinder. The smooth sliding of the piston in the balancer cylinder is the key to the reliable operation of the balancer. This requires ensuring the operating...
