Abstract
The invention discloses a precise combination broach. The precise combination broach is prepared from, by weight, 72-85 parts of tungsten boride, 5-8 parts of niobium disilicide, 0.08-0.1 part of Al, 0.08-0.1 part of Fe, 1-1.5 parts of Mo, 1.3-2.5 parts of hydroxy iron powder, 1.3-2.2 parts of TiC, 0.8-2.1 parts of hydroxy iron powder, 0.08-0.1 part of Mn and 0.2-0.6 part of amide. The broach obtained through the broach material formula and the processing process has a series of excellent performance such as high strength and hardness, good abrasion resistance and red hardness, the small thermal expansion coefficient, the high elasticity modulus and good chemical stability, and the operation is widely applied to various broaches.
Description
Technical field
The present invention relates to a kind of precision combination broach.
Background technology
Forming tool for broaching.Multiple rows of cutter tooth is had on tool surface, the size and dimension of each row's cutter tooth is from incision end
Increase successively and change to cutting out end.When broaching motion made by broaching tool, each cutter tooth just cuts certain thickness gold from workpiece
Belong to, finally give required size and dimension.Broaching tool be usually used in batch and a large amount of produce in processing circular hole, splined hole, keyway,
Plane and profiled surface etc., productivity ratio is very high.The difference at finished surface position pressed by broaching tool, is divided into inside broach and broach for external bracing；By work
The difference of force way when making, is divided into broaching tool and push broach.Push broach is usually used in the type hole after calibrating heat treatment.
But because broaching tool toughness of material is not high enough, hardness is low, after a period of time, local would tend to occur and scratch defect
When, for example, cutter tooth cutting edge has the breach damaged；Broaching tool shape of chip pocket after multiple sharpening causes rough step
Shape, to cause chip curling smoothly not squeeze bad. cutter tooth and scuffing finished surface etc..
