Shearing assembly and shearing machine

Abstract

The invention provides a shearing assembly and a shearing machine, and relates to the technical field of shearing machines. The shearing assembly comprises a movable cutter assembly, a fixed cutter assembly and a power source; the movable cutter assembly comprises a movable cutter holder and a movable cutter installed on the movable cutter holder; the movable cutter is provided with a shearing cutting edge consisting of a transverse cutting edge and a longitudinal cutting edge; and the orthographic projection of the shearing cutting edge in the y-axis direction is in a step shape. The y-axis direction is the moving direction of the movable cutter assembly; the longitudinal cutting edge is provided with a front end close to the feeding side and a rear end close to the discharging side; and in the z-axis direction, the front end and the rear end are the same in position or the rear end is located in the positive direction of the front end. The z-axis direction is perpendicular to the x-axis direction and the y-axis direction; the x-axis direction is a feeding direction; in the z-axis direction, the direction from the fixed cutter to the movable cutter is set to be the positive direction; and according to the shearing assembly, on the basis that the step-shaped shearing cutting edge is adopted, the material can be sheared into a plurality of blocks at a time, and higher production efficiency is achieved.

Description

technical field [0001] The present application relates to the technical field of shearing machines, in particular to a shearing assembly and a shearing machine. Background technique [0002] The shearing machine is suitable for metal recycling processing plants, scrapped car dismantling sites, smelting and casting industries, for cold shearing, pressing and flanging of various shapes of steel and various metal materials, as well as powder products, plastics, glass steel, insulation, etc. Press molding of materials and rubber. The most commonly used metal shears are crocodile shears and gantry shears. [0003] The scrap steel shearing machine is provided with two blade assemblies, and the material is cut through the relative movement of the two blade assemblies. Some scrap steel shearing machines use bent blades to cut materials. For example, Chinese patent 201310704426.0 discloses a stepped combined shearing edge, which consists of an upper shearing edge and a lower sheari...

AI Technical Summary

Problems solved by technology

This type of shearing machine has the following defects: reference figure 1 The cutting edge 11 of the moving knife 10 and the cutting edge 21 of the fixed knife 20 are concave-convex and opposite to each other. When the moving knife structure or the fixed knife structure is subjected to lateral displacement due to force, it may cause abnormal wear of the blade.
