Abstract
This utility model is related to a kind of five metals machining tool, particularly a kind of hard alloy bulb milling cutter.The hard alloy bulb milling cutter, including bulb, shank, the bulb is fixedly connected with shank, it is characterized in that the bulb is provided with four equally distributed peripheral cutting edges, four peripheral cutting edges intersect at the summit of bulb, there is between adjacent peripheral cutting edge backlash.Four peripheral cutting edges meet at bulb center, improve the chisel edge intensity at bulb center, improve milling efficiency.The grooved of backlash described in the utility model adopts Open architecture, is more beneficial for the discharge of chip, and open backlash designs chip removal is more smooth, and chip space is bigger.Diameter of the bulb cross-sectional diameter described in the utility model less than shank cross section.The design of necking down can reduce the chip to workpiece and impact.This utility model relative to prior art, with advantages below：Reasonable in design, bulb intensity are high, easy to use, and chip impact is little, and chip removal is more smooth, and chip space is bigger.
Description
Technical field
This utility model is related to a kind of five metals machining tool, is a kind of sintered carbide ball suitable for mechanical processing industry
Head milling cutter.
Background technology
In terms of hard processing and milling, also in the starting stage, compare same kind of products at abroad and also there is no small difference in the current country
Away from.Manufacture field in HRC50～60 is always external product and is leading us, and traditional backlash is usually that 2 swords cross center,
In high-speed cutting, the cutter of user is easily impacted by bigger, and chip removal is also not smooth enough, improves use cost.
The content of the invention
Technical problem to be solved in the utility model is to overcome the above-mentioned deficiency in the presence of prior art, and provides one
Kind of reasonable in design, easy to use, chip impact is little, and chip removal is more smooth, chip space it is bigger with new backlash designs
Hard alloy bulb milling cutter.
This utility model solves the technical scheme that adopted of above-mentioned technical problem：The hard alloy bulb milling cutter, including
Bulb, shank, the bulb are fixedly connected with shank, it is characterized in that the bulb is provided with four equally distributed periphery cuttings
Sword, four peripheral cutting edges intersect at the summit of bulb, have backlash between adjacent peripheral cutting edge.Four peripheral cutting edges are handed over
In bulb center, the chisel edge intensity at bulb center is substantially increased, milling efficiency is improve.
Backlash described in the utility model adopts Open architecture and is located at behind peripheral cutting edge rotation direction, more favorably
In the discharge of chip, open backlash designs chip removal is more smooth, and chip space is bigger.
Diameter of the bulb cross-sectional diameter described in the utility model less than shank cross section.The design of necking down can reduce to work
The chip impact of part.
Bulb described in the utility model is made using 0.4 micron of ultra-fine grain bar of high-quality.
Bulb described in the utility model is provided with multi-layer wear-resistant composite coating.
This utility model relative to prior art, with advantages below：Reasonable in design, bulb intensity are high, user
Just, chip impact is little, and chip removal is more smooth, and chip space is bigger.

Specific embodiment
Embodiment:
Referring to Fig. 1, Fig. 2, the present embodiment hard alloy bulb milling cutter：Including bulb 1, shank 2, backlash 3, peripheral cutting edge
5.Bulb 1 is fixedly connected with shank 2, and bulb 1 is provided with four equally distributed peripheral cutting edges 5, four 5 phases of peripheral cutting edge
Meet at the summit 4 of bulb 1（Central point）, there is between adjacent peripheral cutting edge 5 backlash 3, bulb 1 is designed using necking down, i.e. ball
Diameter of 1 cross-sectional diameter less than 2 cross section of shank.
Backlash described in the utility model 3 is located at behind 5 rotation direction of peripheral cutting edge.
Bulb of the present utility model 1 is designed as four peripheral cutting edges 5 and meets at 1 center of bulb, substantially increases in bulb 1
The intensity of the heart, while the grooved of backlash 3 adopts Open architecture, is more beneficial for the discharge of chip.In high-speed cutting, three all
Side cutting edge hands over the design at center double than traditional structure intensity, and open backlash designs chip removal is more smooth, holds bits
Space is bigger.Necking down design can reduce the chip to workpiece and impact.
Simple deformation or the combination of every this utility model embodiment technical scheme and technical characteristic, is deemed to fall this
The protection domain of utility model.
