Industrial automatic cutting device

Abstract

The invention relates to a shearing device and particularly discloses an industrial automatic cutting device comprising a pair of oppositely arranged conveying rollers, a connecting rod and a cuttingtable. A gap is reserved between the two conveying rollers, and a to-be-cut part can pass through the gap. One side of the gap is opposite to the cutting table. The connecting rod is arranged over thecutting table. Cutters are installed on the connecting rod along the rod surface. The industrial automatic cutting device is characterized by further comprising a first pushing oil cylinder, a secondpushing oil cylinder and a transmission chain structure; the first pushing oil cylinder is fixedly connected to the cutting table; the pushing end of the first pushing oil cylinder is hinged to the connecting rod; and a button type pressure increasing valve is installed on the first pushing oil cylinder and is located on the rotation path of the end, away from the cutters, of the connecting rod.According to the technical scheme, the cutting angles of the cutters are adjusted periodically, thus the cutting angle of the whole cutting process is limited within a fixed range, load change and local deformation of the cut position of a metal sheet are reduced, and precision of metal surface analysis is promoted.

Description

technical field [0001] The invention belongs to the technical field with an international classification number of B23D15, and in particular relates to a shearing device. Background technique [0002] In the experiment on the analysis of large-area stainless steel flake surface samples, due to the large size of the metal flakes, the experiment cannot be carried out directly, and the number is difficult to meet the experimental needs. According to the experimental sample rules, large-sized flake samples can be cut and prepared into uniform samples for experiments. In order to reduce the sampling amount and ensure the accuracy of the experimental results, the size of the sample needs to be small and the uniformity should be good. During the sample preparation process, impurities should not be mixed and the shape of the sample should not be changed. Therefore, the requirements for sample preparation are very stringent. [0003] Based on the above technical problems, the Chine...

Problems solved by technology

[0004] During the implementation of the above-mentioned technical solution, technicians can extend the length of the cutting knife to adapt to the wide metal sheet, but since the connecting rod is installed on the machine base, the rotation center of the connecting rod is fixed, and the upper cutting on the connecting rod The knife rotates around a fixed center, causing the cutting angle of the upper cutter to gradually decrease when cutting the metal sheet, that is, the load on the shearing part of the metal sheet is always changing, resulting in a large change in the internal structure of the metal sheet cutting part, cutting Changing the angle all the time will easily lead to different deformation degrees of the cut parts of the rotating metal sheet, which also affects the accuracy of the experimental analysis
