Punch safety door anti-falling device

Abstract

The invention relates to a punch safety door anti-falling device. The punch safety door anti-falling device comprises a safety door and guide rails, the guide rails are mounted on the two sides of thefront end of a punch body, the safety door capable of ascending and descending in the up-down direction is mounted on the guide rails, anti-falling assemblies are transversely mounted on one sides ofthe upper ends of the guide rails and comprise mounting bottom plates and air cylinders, front supporting plates are vertically mounted at the ends, facing the guide rails, of the upper sides of themounting bottom plates, blocking pins are arranged on the front supporting plates in a transversely penetrating mode, one ends of the blocking pins are axially connected with extending rods of the aircylinders mounted on the upper sides of the mounting bottom plates, and the other ends of the blocking pins extend into the safety door along with pushing out of the air cylinders. The punch safety door is prevented from falling through a simple mechanism, structure disassembling and assembling are easy, the reliable and durable effects are achieved, and safety accidents are avoided.

Description

technical field [0001] The invention relates to the field of punch press structures, in particular to an anti-drop device for a safety door of a punch press. Background technique [0002] The punching machine includes upper and lower worktables, and the processing operation is carried out by driving the upper worktable to move up and down. During the working process of the punch press, the downward movement of the upper table will generate a huge momentum. The work space between the upper and lower workbenches of the current punch press is all exposed, and the staff operates near the punch press, so there is a certain potential safety hazard. Once the body of the staff is sandwiched between the upper and lower workbenches It will cause serious production accidents, and there are serious safety hazards, so now many punching machines are equipped with safety doors that can be opened, and the opening methods of the safety doors are mostly lifting and opening. [0003] For exa...

AI Technical Summary

Problems solved by technology

[0004] But now there is a problem that when the safety door is raised to the upper position, it is locked by the electric hoist, oil cylinder, and air cylinder to prevent it from falling, but these methods are not safe. If the power failure or the pipeline of the oil cylinder is broken All can cause the safety door to fall automatically. If the operator is just at the lower end of the safety door, it will cause a safety accident. Therefore, it is necessary to design a reliable safety door anti-drop mechanism.
