Abstract

The invention discloses a stamping die edge block for silicon steel sheets and a processing technique thereof. The processing technique of the edge block comprises planning-milling and linear cuttingprocedures. In addition, in the whole process flow, the common dimensions of the edge block are firstly processed and then the critical dimensions of the edge block are processed. The stamping die edgeblock for silicon steel sheets has a wider main body in replacement of the long and narrow body of the prior edge block. In addition, the bland of the die edge block is proportioned in singe piece,th us reducing the release of the total stress and deformation correspondingly. The stamping die edge block for silicon steel sheets and the processing technique thereof can better solve the problem ofstress release and ensure the machining precision of the die edge block, thereby ensuring that high quality silicon steel sheets are produced through the die edge block.

Description

A kind of processing technology of punching mould edge block of silicone steel sheet
Technical field
The present invention relates to a kind of processing technology of diel of silicon steel sheet, more particularly, relate to a kind of processing technology of punching mould edge block of silicone steel sheet.
Background technology
In the diel field, one secondary mould generally is divided into punch and die, all contain the sword piece in punch and the die, punch sword piece and die sword piece coupling, punch moves downward, cooperate the raw material that will be placed on the die to be stamped into part by punch sword piece and die sword piece ground, this shows that the machining accuracy of sword piece (punch sword piece and die sword piece) of diel is of crucial importance for the part quality that punching out goes out.Some present motor the insides need electrode silicon steel sheet 1 (shown in Figure 1), and the precision of electrode silicon steel sheet 1 directly influences the quality of motor, and electrode silicon steel sheet 1 is exactly by the diel punching out, so the precision of the sword piece of this diel just seems important unusually.At present the punch of the diel of electrode silicon steel sheet 1 and die all by several mould sword pieces around be assembled (shown in Figure 2).Present electrode silicon steel sheet mould sword piece 5 (shown in Figure 5) and technology thereof have following correlated characteristic: 1) blanks of mould sword piece 5 is that (shown in Figure 3) joined by many companies; 2) mould sword piece 5 profiles are all finished by wire cutting machine; 3) mould sword piece 5 profiles are curved, and intermediate width is little; 4) cut critical size on the technology earlier, cut non-key size at last.
In production practices, 3 features with mold sword piece 5 and technology thereof have shown shortcoming, influenced its precision: 1) because the blanks of mould sword piece 5 is that many companies join, so the internal stress that produces when early stage machined, transportation and heat treatment all is not easy to discharge, together discharge when making the online cutting of too much stress, increased distortion.2) because mould sword piece 5 profiles are all finished by wire cutting machine,, be easy to generate distortion so stress release does not have rule; 3) because mould sword piece 5 profiles are curved, intermediate width is little, and workpiece is a thin-and-long, and the distortion meeting that stress release produces in the process is more a lot of greatly than the distortion that non-long and narrow workpiece produces, and is difficult to solve by processing technology.4), cause stress release, cutting critical size distortion before making during the non-key size of cutting after the institute because first cutting critical size on the technology cuts non-key size at last.
Summary of the invention
The present invention aims to provide a kind of processing technology of punching mould edge block of silicone steel sheet, can solve the stress release problem preferably, guarantees the machining accuracy of described mould sword piece, thereby guarantees to produce high-quality silicon steel sheet.
