Device for blanking blanks of circular saw

Abstract

The invention provides a device for blanking blanks of a circular saw. The device comprises a rack, wherein, a rotary working table is arranged on the rack; a vertical regulating device and a horizontal regulating device are arranged on the rotary working table; a rotation driving device is mounted at the other end of the rack; the rotation driving device is connected with an upper shearing wheelof an upper tool apron via an upper transmission connecting rod; a lifting device is arranged at the upper part of the upper tool apron and connected with the upper tool apron; the rotation driving device is connected with a lower shearing wheel of a lower tool apron via a lower transmission connecting rod; the lower tool apron is fixedly connected with the rack; the upper shearing wheel is matched with the lower shearing wheel; and an acute angle is formed by projecting the axes of the upper shearing wheel and the lower shearing wheel onto a vertical plane. By dispensing with the procedures of annealing and roughing after blanking, the device provided by the invention can simplify the procedures for processing circular saw blades, improve the efficiency and save raw materials; and the processed blanks of the circular saw has the advantages of neat and smooth edges and high quality.

Description

technical field [0001] The invention relates to a metal cutting device, in particular to a blanking device for cutting circular blanks required by circular saws. Background technique [0002] At present, the sawing industry generally adopts the gas cutting method for blanking. The process of processing circular saw blades by gas cutting method is: sheet metal - gas cutting blanking - annealing - rough turning - tooth punching. The disadvantages are as follows: first, the processing technology is complicated. The processing accuracy is poor. Since gas cutting is a kind of thermal cutting, the cut material is easily deformed, and the structure of the material may also change. Usually, in order to restore the original performance of the plate, annealing is required after cutting. Gas cutting The edge of the circular plate coming out is not neat, and it must be processed through rough turning; the second is that the utilization rate of raw materials is low and the cost increases...
