Detailed description of the invention
The technical problem solved to make the utility model, technical scheme and beneficial effect are clearly understood, below in conjunction with embodiment, are further elaborated to the utility model.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
The utility model provides a kind of carbide alloy pressed compact shoulder hole processing broad, as seen in figures 3-6, for processing the carbide alloy pressed compact shoulder hole forming bottom outlet, comprise the flat blade 2 of handle of a knife 1 and one installation, flat blade 1 is welded in the cannelure of handle of a knife 1 in the mode of brazing, the dual-side of flat blade 2 forms circumference sword 3, and the symmetrical centre that base forms two sections of shear blades, 4, two sections of shear blades 4 is provided with central recess 5.Flat blade 2 adopts Hardmetal materials to make, and handle of a knife 1 is made for cylindrical 45# steel.
Embodiment 1: a kind of carbide alloy pressed compact shoulder hole processing broad, as seen in figures 3-6, for processing rigid alloy pressed compact band shoulder hole, carbide alloy pressed compact is processed with bottom outlet, the diameter of bottom outlet is 10mm, and counter bore diameter is 20mm, and the shoulder hole degree of depth is 10mm.
In the present embodiment, the blade 2 length A of carbide alloy pressed compact shoulder hole processing broad is 39mm, and width B is 19.10mm, and thickness H is 3.3mm, arranges changeover portion, offer central channel between blade 2 liang of shear blades.The width L of central recess 5 is compared with the little 1mm of pressed compact bottom diameter, and namely the width L of central recess is 9mm, and circumference edge clearance angle α is 11 °, and shear blade relief angle β is 11 °, and fall the fillet of R1 at the intersection place of knife face and cutter hub after shear blade 4.Handle of a knife 1 length is 78mm, and diameter is 10mm, and handle of a knife 1 end has the cannelure of 20mm, and groove width is 3.3mm, and blade 2 is embedded in the cannelure of handle of a knife 1, and mosaic mode is brazing welding.Under processing operating mode, the cutter of the present embodiment due to blade be flat, circumference sword 3 has wider chip pocket when cutting, central recess 5 corresponds to the bottom outlet of carbide alloy pressed compact, when shear blade 4 cuts, cutting swarf can be discharged in time from bottom outlet, and overcoming cutting swarf in conventional helical chip removal mode can only from the defect of axially discharging, avoid extruding pressed compact inwall and the edge of machine-shaping, improve product percent of pass.
On the other hand, the cutter that the utility model provides is brazed shank tool, and blade adopts Hardmetal materials to make, and handle of a knife is made up of cylindrical 45# steel, has so both efficiently solved because pressed compact hardness is high, the problem that tool wear is large, can reduce material cost.
