Description

Technical Field

[0001] The utility model relates to the technical field of safety bolts for press machines, and more particularly to a safety bolt structure for press machines. Background Art

[0002] The main function of the press safety bolt is to prevent accidental startup and protect the safety of maintenance personnel. The press safety bolt structure is mainly composed of a mounting frame and a latch. The mounting frame is usually fixed on the top of the press. When the mobile end of the press rises and stops, the mounting frame will dock with the mobile end, and then the two will be fixed by inserting the latch, thereby achieving a fixing effect on the mobile end of the press, thereby preventing the mobile end of the press from accidentally falling and avoiding personal injury.

[0003] When using the existing press safety bolt structure, the press is usually stopped and the personnel manually insert the pin to fix the mounting frame and the mobile end of the press. The operation is cumbersome and makes the device inconvenient and inefficient to use. In view of this, we propose a press safety bolt structure. Utility Model Content
