Abstract

A precision shearing die of rod material for press is composed of upper and lower die plates, upper and lower fixed cutter carriers, upper and lower cutting blades, and the upper and lower clamp units consisting of clamping block, clamping spring, screw bolt and fixed block.

Description

technical field [0001] The invention relates to a bar precision shearing die, which belongs to a bar precision shearing die used on a general press. Background technique [0002] At present, in the field of mechanical processing, the blanking of bars still adopts the method of shearing by a press. Although this method has the advantages of high blanking efficiency and low material loss rate. However, because the mold cannot be used for cutting and blanking, the use of this press cannot improve the section quality of the precision forging blank and reduce the cutting deformation. Therefore, it has the disadvantages of low blanking precision, poor cross-sectional quality of the blank and many cross-sectional defects of cutting. Contents of the invention [0003] The purpose of the present invention is to solve the technical difficulties of low precision blanking blank, poor section quality of the blank and many section defects in the shearing bar of the existing press, and ...
