Abstract

The invention relates to an overload connection joint mechanism which comprises a sealing connection part and a filtering pressure relief part. One end of the sealing connection part communicates withan oil cylinder in a sealing way; the other end of the sealing connection part is connected with the filtering pressure relief part in a sealing way; the sealing connection part comprises an elasticsealing piece, a pressing connection piece and a connecting oil pipe; and the filtering pressure relief part comprises an oil tank, a filter box and a buffer air bag. The overload connection joint mechanism has the advantages of reliability in sealing, convenience in installing, low technical requirement on installation, and stable performance.

Description

technical field [0001] The invention relates to the slide part of a press, especially the overload connection joint part. Background technique [0002] A press is a device used for stamping in the field of mechanical manufacturing. Generally, in order to avoid damage to the parts caused by the applied force exceeding the rated applied force during stamping, most of the presses use overload protection devices to avoid the above situation, and the overload protection devices are generally connected to oil cylinders for pressure relief. Now a large number of press overload protection devices are connected to the oil cylinder by threaded connection or direct end connection. However, the sealing of the above-mentioned connecting structure is unreliable, which is likely to cause oil leakage and frequent alarms, and requires relatively high installation skills. [0003] Therefore, how to improve the existing overload connection joint mechanism to overcome the above-mentioned exis...
