Plate shearing machine tool rest with locking mechanism and tool thereof

Abstract

The invention discloses a plate shearing machine tool rest with a locking mechanism and a tool thereof. The plate shearing machine tool rest comprises an upper tool rest module and a lower tool rest module. The upper tool rest module and the lower tool rest module are fixed to a plate shearing machine platform. The upper tool rest module comprises an upper tool rest body, an upper tool body and tool guide rails, the tool guide rails are fixed to the two sides of the upper tool rest body, and the upper tool body is embedded into grooves of the tool guide rails and slides up and down in a fixed stroke. The lower tool rest module comprises a lower tool rest body and a lower tool body, and the lower tool body is fixed to one side of the lower tool rest body. The plate shearing machine tool rest has the beneficial effects that (1) final motion of an upper blade and a lower blade is reduced through the locking mechanism, the eccentric shearing phenomenon is eliminated, twisting of plates is reduced, and the quality of workpieces is improved; and (2) a step-shaped corrugated surface blade is adopted as the upper blade, the rigidity, hardness, abrasion resistance, fatigue strength, toughness and the like of blade steel are greatly improved, burrs and flangings of machined faces are effectively reduced, and the technical performance and production efficiency of a plate shearing machine are improved.

Description

Technical field [0001] The invention relates to the field of shearing processing machinery, in particular to a shearing machine tool holder with a locking mechanism and its cutter. Background technique [0002] Shearing machine is a common processing equipment used to cut metal materials in the metal processing industry. It is mainly used for cutting sheet metal workpieces. It has the characteristics of simple operation and high work efficiency. In the process of product processing, the shearing machine is the equipment to make the plate reach the specified size by cutting the head, trimming, trimming and other methods. Because the shearing machine has the advantages of being able to cut various lengths of plates and also cut the local defects of the plates, it is widely used in metallurgy, light industry, construction and other fields. [0003] In actual use, many shearing machines work with overload and require high shearing accuracy. The existing shearing equipment has a rather...

AI Technical Summary

Problems solved by technology

During the shearing process, the blade wears a lot and is prone to problems such as flanging. There are defects such as waste of materials and excessive weight of the overall structure. Not only the manufacturing cost increases, but also the transportation and installation become quite difficult.
