Blade clamping structure of novel plate shearing machine

Abstract

The invention relates to a blade clamping structure of a novel plate shearing machine. The structure comprises an upper blade, a lower blade and a base, wherein a groove is formed in the base; the lower blade is arranged in the groove; wedged blocks are respectively arranged at the left and right sides of the lower blade; and the upper blade fitting the lower blade is arranged in an edge of the lower blade. At present, in the assembly of blades in general plate shearing machines, the blades are directly fixed on a tool post by using screws, so that the requirements on assembly and later tool replacement are higher; and the tool adjusting structure is complex, so that the blade adjustment is troublesome, both time and labor are wasted, and the tool gap is difficultly adjusted. The lower blade is free of screw holes; the installation positioning and the gap adjustment are both dependent on a mutual locking effect of the V-shaped groove and the inclined wedges, so that the effects of stability and reliability are achieved, the manual assembly time is shortened, and the tool replacement degree is high; and in addition, the structure has such characteristics as easy adjustment of the tool gap, capability of making up the straightness defect in the tool machining and convenience for tool installation and disassembly.

Description

technical field [0001] The invention relates to the technical field of corrugated sheet shearing machines, in particular to a novel shearing machine blade clamping structure. Background technique [0002] In the machining industry, the development of cutting tools has entered the era of the development of mechanical clamping tools, but most of the machine clamping tools used in the machining industry currently have the following two problems: one is due to the clamping and adjustment of the blade. Complexity makes it difficult to manufacture the tool, the number of teeth that can be arranged is small, the operation is inconvenient in actual use, and the cutting efficiency is difficult to improve; secondly, due to the complex structure of the tool adjustment, the adjustment of the blade is difficult, time-consuming and laborious, and the tool clearance is difficult to adjust. Affecting the straightness of the machining tool can lead to abnormal wear of the tool, reduced servi...

[0002] In the machining industry, the development of cutting tools has entered the era of the development of mechanical clamping tools, but most of the machine clamping tools used in the machining industry currently have the following two problems: one is due to the clamping and adjustment of the blade. Complexity makes it difficult to manufacture the tool, the number of teeth that can be arranged is small, the operation is inconvenient in actual use, and the cutting efficiency is difficult to improve; secondly, due to the complex structure of the tool adjustment, the adjustment of the blade is difficult, time-consuming and laborious, and the tool clearance is difficult to adjust. Affecting the straightness of the machining tool can lead to abnormal wear of the tool, reduced service life, and also affects the production quality of the finished product; the third is that the existing blade is directly fixed on the tool holder with screws when assembling. High requirements are placed on both assembly and post-tool change
