Description
Technical field
Carbide chip manufacture field is the utility model is related to, more particularly to a kind of indexable knife for shallow hole drilling
Piece.
Background technology
In machining, the semienclosed metal cutting of drilling generally use, chip is difficult to free discharge, squeezed
In the hole of brill, result in blockage, cause the temperature of drill bit drastically to increase, exacerbate bit wear.Therefore, drilling processing need to solve resolution
Bits and this problem of chip removal.For hard alloy shallow hole drilling, can this key issue of preferably chip breaking embody a concentrated reflection of hard
On the chipbreaker structures of alloy indexable insert tip, throw away tip.Chip-breaker not only plays additional deformation to chip, and can also realize control
The curling of cutting is made with fractureing, as long as the inclination angle of the profile of chip-breaker, size and chip-breaker and main cutting edge is suitable, then chip breaking
It is very reliable.It is unreasonable to be currently used for processing the configuration design of the chip-breaker of railway hot rolled rail blade, causes in processing to cutting
The control of bits is bad, has had a strong impact on the service life, production efficiency, quality of materials of lathe and blade.Therefore, to existing shallow bore hole
The chip-breaker of drill blade optimizes improvement, it will help improves chip breaking and the chip removal performance of blade, improves hard alloy shallow bore hole
Bore service life and operating efficiency.
The content of the invention
The purpose of this utility model be to provide it is a kind of help to improve blade chip breaking and chip removal performance be used for shallow hole drilling
Indexable insert tip, throw away tip.
The purpose of this utility model is achieved through the following technical solutions:
A kind of indexable insert tip, throw away tip for shallow hole drilling, the indexable hard alloy of W types that indexable insert tip, throw away tip is adopted international standards
Blade, indexable insert tip, throw away tip center are provided with centre bore, and the main cutting edge side of indexable insert tip, throw away tip is provided with bottom as the disconnected of Gothic
Consider groove to be worth doing, every main cutting edge is provided with multiple chip removal breach.
Further, the radius r of a circular arc of Gothic chip-breaker1For 0.5mm~0.55mm, another circular arc
Radius r2For 0.7mm~0.75mm
Further, the preceding angle number r of the chip-breaker0For 11 °~12 °, the rear angle number α of chip-breaker is 7 °, chip breaking
The cutting edge height h of groove is 0.35mm, and the depth capacity H of chip-breaker is 0.58mm, and the anti-angle θ that considers to be worth doing is 65 °.
Further, the chip removal breach on every main cutting edge is 3, the radius r of chip removal breach01For 0.66mm.
Further, the width Wa of the chip-breaker is 2~2.2mm.
Further, the blade main cutting edge is provided with rib band, the width b of rib bandr1For 0.13~0.15mm.
Chip removal breach on the cutting edge of the utility model indexable insert tip, throw away tip can improve chip removal efficiency during drilling, bicircular arcs
The chip-breaker of shape makes chip crimp twice to fracture, more conducively scrap fallaway, and the rib band at cutting edge cutting edge makes indexable insert tip, throw away tip more
Add wear-resisting, the durability and production efficiency of indexable insert tip, throw away tip can be improved, ensure the surface quality of product to be processed.

Consider groove 4 to be worth doing, as shown in figure 3, the bottom plate of chip-breaker 4 is in Gothic, the radius r of a circular arc1For 0.5mm, another circular arc
Radius r2For 0.75mm, the preceding angle number r of chip-breaker 40For 11 °, the rear angle number α of chip-breaker 4 is 7 °, and blade main cutting edge 2 is set
There are rib band, the width br of rib band1For 0.15mm.The width Wa of chip-breaker 4 is 2.2mm, and the cutting edge height h of chip-breaker 4 is
0.35mm, the depth capacity H of chip-breaker 4 is 0.58mm, and the anti-angle θ that considers to be worth doing is 65 °.Every main cutting edge 2 is provided with 3 chip removal breach
3, the radius r of chip removal breach 301For 0.66mm.
Embodiment 2
The structure of the present embodiment is substantially the same manner as Example 1, and only following parameter is modified, and is specifically:Main cutting
The width b of the rib band of sword 2r1For 0.13mm;One arc radius r of Gothic chip-breaker 41For 0.55mm, another circular arc half
Footpath r2For 0.7mm, the preceding angle number r of chip-breaker 40For 12 °, the width Wa of chip-breaker 4 is 2mm, and depth capacity H is 0.56mm.
