Description

A kind of mold production band sawing machine

【Technical field】

The utility model is related to a kind of technical fields of mold production band sawing machine.

【Background technology】

Mold in process of production, generally requires and mold production is carried out by band sawing machine to cut into one with metal bar material Measured length, of the prior art, the clamping device of band sawing machine to the fixation of metal bar material is pressed respectively against by two grip slippers It realizes and grips on the front and rear sides of metal bar material, and hold-down mechanism is not provided on the upside of metal bar material, work as metal Bar material residue to it is a certain amount of when, the position of grip slipper clamping metal bar material is reduced, in the cutting force by saw blade from band It is skidded off in the stationary fixture of blade saw machine tool, particularly hollow bar material, clamping is tightly easily deformed very much.

When using band saw cutter cut-out metal material, the tooth top in the sawtooth of band saw cutter is attached with chip and generates product sometimes Bits knurl.If generating the built-up edge, it is thicker to occur cutting plane repeatedly, and built-up edge comes off from tooth top, according to circumstances sometimes Hinder sword because impact is generated in tooth top.Therefore, by the rotating brush that is rotated up in the side orthogonal with band saw cutter direction of travel come into Row is attached to the removing of the chip on band saw cutter.

However, the high size of tooth of multiple sawtooth of band saw cutter and the tooth pitch of each sawtooth are not necessarily constant, and straight-tooth And the configuration relation of the side set of left and right is nor constant, thus the abrasion of above-mentioned rotating brush also not necessarily becomes constant, sometimes Such as partial wear and form shape as polygon.As a result, in the chip for using rotating brush be attached on band saw cutter During removal, rotating brush sometimes relative to band saw cutter close to or away from direction on (rotating brush relative to band saw cutter lap The direction for becoming larger or becoming smaller) vibration is generated, so as to sometimes because the interference of rotating brush and band saw cutter leads to rotating brush to far from band saw It substantially bounces in the direction of knife.So as to which smear removal effect is poor, hairbrush service life is short.
