Abstract

The invention relates to a combined cutter for uniform shearing of a pipe body, comprising an upper shearing knife that can move up and down and a fixed lower shearing knife, the upper shearing knife includes an upper knife body and an upper blade, and the lower shearing knife The cutting knife includes a lower knife body and a lower knife edge, and both the upper knife edge and the lower knife edge have arc-shaped knife edges; the invention also relates to a working method for uniformly cutting a pipe body with a combined knife. In the tube body shearing combination tool of the present invention, the arc-shaped edge of the upper blade and the arc-shaped edge of the lower blade work together to make the shearing force more uniform, and it is easy to complete the cutting. The heat generated during the cutting process is small, the wear of the upper blade and the lower blade is small, and the phenomenon of chipping is avoided or reduced. Therefore, the structure design of the present invention is simple and reasonable, the cutting quality and cutting efficiency are high, the tool life is long, and the production cost is low. application prospects.

Description

technical field [0001] The invention relates to a pipe body uniform shearing combined cutter and a working method thereof. Background technique [0002] In the process of making a precision composite alloy tube element equipped with flammable powder and cutting it into small sections, the requirements for the cutting incision are high, the heat generated during the shearing process should be small, and the densely drawn drug core in the tube is not After the block is dropped, the cut pipe body must have good end surface flatness and high roundness. At present, for a composite alloy tube with a flammable powder core, it is necessary to avoid excessive heat during cutting and ignite the core in the tube, resulting in scrapping. Therefore, the sawing mode of repeated friction and heat generation cannot be used, and only shearing can be used. In the existing shearing production, the knives used are all flat-edged knives, which cut in one direction. When shearing, due to the sma...
