Abstract
The invention discloses a diamond tool bit for machining an automobile aluminum alloy wheel. The tool bit is round, the width of a cutting edge strip of the tool bit is 0.2 mm, and the main rear angle of the cutting edge strip of the tool bit is -2 degrees. The tool bit is made of diamond, and the tool bit is welded to a hard alloy tool bar. Due to the fact that the design that the traditional tool width is 0 mm and the main rear angle is 7 degrees is changed, an extrusion cutting strip is formed by the wheel in the cutting process, the surface of an aluminum alloy casting is subjected to compressional deformation quickly in the high-speed cutting process, and thus the purpose of repairing needle holes and the purpose of loosening are achieved. For the reason that the tool bit is made of diamond, when the tool bit with extremely-high hardness is used for cutting low hardness products such as the aluminum alloy wheel, the brightness of the surfaces of the products can be improved quickly, and hence the effect that the surface of the wheel is as bright as a sixpence can be achieved. By changing the structure and the material of the tool bit, the casting defects are overcome and the product appearance is improved.
Description
Technical field
The present invention relates to auto parts and components field of machining, relate in particular to a kind of aluminum alloy wheel of vehicle machining diamond segment.
Background technology
Machining is that aluminum wheel of vehicle manufactures important production link.Wheel generally completes mechanical processing process after heat treatment completes on numerically controlled lathe and numerical control machining center.In aluminum vehicle wheel Tutrning Process, the general hard alloy cutter that adopts is processed, and the feature of this cutter is sharper, and tread is generally designed to 0mm, and primary clearance is 7 °, is easy to cut, but does not have repair to wheel blanks outward appearance spoke part.Owing to having completed melting, casting, heat treatment step before wheel machining, by the impact of the many factors such as technique, weather, equipment, can not accomplish that degasification thoroughly removes the gred to aluminium liquid in fusion process, therefore after product has been cast, pin hole, the defect such as loose is often there is on surface, can there is bubble in surface treatment process after mechanical machining is complete in above defect, have a strong impact on product appearance and even often cause product rejection.What require automotive wheel along with domestic and international market improves constantly, and people no longer meet the use value that wheel possesses as a practical part, and requires that it has higher exterior quality, and the existence of above problem obviously can not meet the demand in market; Adopt the wheel surface brightness of hard alloy cutter processing general in addition, can not meet the requirement that client is more and more higher to shiny appearance degree, therefore aluminum wheel of vehicle industry needs constantly bring forth new ideas mechanical processing technique and equipment.
Summary of the invention
The object of the invention is to overcome existing aluminum alloy wheel of vehicle industry generally adopts carbide cutter tool to carry out the defect of machining, a kind of energy multiple wear wheel casting flaw is provided, the process tool of wheel shiny appearance degree, specifically a kind of aluminum alloy wheel of vehicle machining diamond segment can be improved simultaneously.
The concrete scheme realizing above technology is: a kind of aluminum alloy wheel of vehicle machining diamond segment, and this cutter head is rounded, and cutter head cutting edge bandwidth is 0.2mm, and cutter head cuts land primary clearance and is-2 °; Cutter head material is diamond, and cutter head is welded on carbide alloy knife bar.Owing to changing the design of the wide 0mm of conventional knives, primary clearance 7 °, make wheel in working angles, form an extruding and cut band, make aluminium alloy castings surface in by the process of high-speed cutting by rapid crimp, thus reach and repair pin hole and loose object.Do cutter head owing to have employed diamond, this cutter head with extreme hardness, when the relatively low product of this hardness of the wheel that cuts aluminum alloy, can make the brightness of product surface be promoted rapidly, thus reach the as bright as a sixpence effect of wheel surface.Change on cutter head structure and material is realized it make up casting flaw by above, highlight the object of product appearance.
Accompanying drawing explanation
Fig. 1 is front view of the present invention;
Fig. 2 is top view of the present invention;
Fig. 3 is the enlarged drawing at Front view 1 position.
Concrete embodiment
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of aluminum alloy wheel of vehicle machining diamond segment, this cutter head 1 is rounded, and it is 0.2mm that cutter head cuts land 2 width, cuts land 2 primary clearance and is-2 °; Cutter head 1 material is diamond, and cutter head 1 is welded on carbide alloy knife bar 3.This cutter head has the effect making up casting flaw, highlight product appearance brightness.
