Description

Technical Field

[0001] The utility model relates to the technical field of production of freight elevator car accessories, in particular to a punching tool for producing anti-collision strips of freight elevator cars. Background Art

[0002] The anti-collision strip of the freight elevator car plays an important role in the safe operation of the freight elevator. Its main functions include: 1) Protect the freight elevator car: The primary function of the anti-collision strip is to reduce the collision between the goods and the freight elevator car during the handling process, thereby reducing the degree of damage to the freight elevator car. Whether it is human operation error or the inertia of the goods themselves, the anti-collision strip can absorb the impact force to a certain extent and effectively protect the freight elevator car. 2) Extend the service life of the freight elevator: Due to the existence of the anti-collision strip, the wear degree of the freight elevator car will be reduced, thereby extending the service life of the freight elevator. This is undoubtedly an economical maintenance method for long-term operation of freight elevators. 3) Improve operation efficiency: The anti-collision strip can also reduce the friction between the goods and the freight elevator car, making the handling of goods smoother, thereby improving the operation efficiency of the freight elevator. 4) Reduce noise: The design of the anti-collision strip often has a certain degree of elasticity, which can produce a buffer when the goods collide, thereby reducing the generation of noise. This is especially important for places that need to be kept quiet, such as hospitals, libraries, etc. 5) Enhanced safety: The use of anti-collision strips can also reduce the risk of accidents caused by collisions to a certain extent and improve the safety of cargo handling.

[0003] During the production process, the anti-collision strips for freight elevators need to be cut using punching tools. The traditional punching tools for the production of anti-collision strips for freight elevators have shortcomings when used. First, it does not have the function of pulling the cut material, and cannot quickly pull the cut material to the front side after cutting; second, it can only punch a single anti-collision strip, which cannot meet the needs of batch punching, and the punching efficiency is relatively low. Therefore, it is necessary to optimize and improve its structure. Utility Model Content
