Problems solved by technology

Take the straight groove broach as an example, which is a kind of broach used for rough machining and grooving. After the straight groove broach has been used for a period of time, it needs to grind its rake face. There will be a burr that turns to the flank at the position. The conventional method of removing the burr is to use a bamboo piece to scrape against the direction of the blade, or use a copper piece to scrape off the burr, but t

Abstract

The invention provides a method for removing burrs of a straight slot broach. In the method, two times of blasting shot in different angles are carried out on a back cutter surface of a cutter tooth through a shot blasting device; shot material used for a first time of blasting shot is carbonic acid clay glass or plastic sand; shot material used for a second time of blasting shot is aluminum oxide; when blasting shot, the shot blasting is sequentially performed on the back cutter surface of each cutter tooth. Due to different shot blasting angles and different shot materials in two times of blasting shot, the effect of cooperatively removing the burrs can be achieved. The method is capable of effectively removing the burrs on the back cutter surface of the cutter tooth, guaranteeing integrity and sharpness of a cutting edge and improving the durability and the working efficiency of a cutter.

Description

Technical field [0001] The invention relates to the field of tool repair in metal chips, in particular to a method for removing burrs on a straight groove broach. Background technique [0002] The broach is a shaped tool used for broaching. The surface of the broach is provided with multiple rows of teeth, and the size and shape of each row of teeth increase and change from the cutting end to the cutting end. When the broach is in broaching motion, each tooth will cut a certain thickness of metal from the workpiece, and finally obtain the required size and shape. Broaches often process round holes, spline holes, keyways, planes, etc. in batch or mass production because of their high work efficiency. During the broaching process, the broach bears different tensile, torsional, compressive, and impact loads and stresses, and its microscopic metallographic structure will change with the increase of use time, so after a period of use The broach needs to be sharpened in time. Take t...
