Abstract
The utility model provides a forming turning tool for machining an external conical surface of a piston outer ring, which comprises a turning tool body. An edge arranged at the front end of the turning tool body is made into a corrugated structure, and the spacing of the corrugated structure is 0.10mm +/- 0.03mm, while the height is 0.015mm +/- 0.005mm. The tip and the edge of the forming turning tool can be prevented from being broken effectively, tool wear is reduced, tool durability is enhanced, the edge is in the micro corrugated structure so that durability of the tool can be enhanced effectively, the durability is increased to more than threes time of the original durability as compared with a conventional forming turning tool for the external conical surface, and machining cost ratio is controlled effectively.
Description
Technical field
The utility model relates to the cutter accessory field that machining is used, and specifically is a kind of shaped profile turning cutter of machining piston ring outer conical surface.
Background technology
At present, the second road piston ring excircle face of most engines is designed to cone structure, and the piston ring excircle conical surface adopts shaped profile turning cutter processing usually, and its blade is a planar structure.
Along with the raising that the piston ring wearability requires, the hardness of piston ring material is also more and more higher, processes more and more difficult; Especially when the moulding car piston ring excircle conical surface, point of a knife and blade that shaped profile turning cutter takes place through regular meeting collapse scarce phenomenon, and the piston ring excircle face forms spike or boss, causes piston ring to scrap, and tool life reduces, and causes the cost ratio can not to be in any more.
Summary of the invention
The utility model is to collapse scarce problem in order to solve piston ring excircle conical surface shaped profile turning cutter point of a knife and blade, to improve tool life, the special shaped profile turning cutter that proposes a kind of machining piston ring outer conical surface.
The technical solution of the utility model is for this reason, and a kind of shaped profile turning cutter of machining piston ring outer conical surface comprises the lathe tool body, and the front end of lathe tool body is provided with blade, it is characterized in that: the blade of lathe tool front end is made into corrugated structure.
Improvement to such scheme is: the corrugated structure of described blade is that spacing is 0.10 ± 0.03mm, highly is the corrugated structure of 0.015 ± 0.005mm.
Beneficial effect:
The utility model is designed to the corrugated structure of spacing 0.10 ± 0.03mm, height 0.015 ± 0.005mm with the blade of shaped profile turning cutter, and it is scarce to prevent effectively that point of a knife and blade from collapsing, and reduces tool wear, improves tool life.Its blade adopts small corrugated structure, can effectively improve tool life, compares with conventional piston ring excircle conical surface shaped profile turning cutter, and tool life is brought up to original more than 3 times, has controlled the processing cost ratio effectively.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is an A point enlarged diagram of the present utility model.
Fig. 3 is the enlarged diagram B that A is ordered among Fig. 2 of the present utility model.
The specific embodiment
The utility model such as Fig. 1, Fig. 2, shown in Figure 3.
The front end of the utility model lathe tool body 1 is provided with blade 2, and blade 2 makes into corrugated structure.
According to the roughness requirement of part, each conical surface blade is designed to the small ripple sword of several spacings 0.097, height 0.015.
Claims (2)
1. the shaped profile turning cutter of a machining piston ring outer conical surface comprises the lathe tool body, and the front end of lathe tool body is provided with blade, it is characterized in that: the blade of lathe tool front end is made into corrugated structure.
2. the shaped profile turning cutter of a kind of machining piston ring outer conical surface according to claim 1 is characterized in that: the corrugated structure of described blade is that spacing is 0.10 ± 0.03mm, highly is the corrugated structure of 0.015 ± 0.005mm.
