Abstract
The utility model relates to an aluminum piston ring slot tool with good chip breaking and chip removing performance. The aluminum piston ring slot tool consists of a tool body, a PCD (Plasma-Coupled Device) blade, an arc-shaped chip winding slot and various cutting angles designed on the tool. Through the special design of various cutting angles on the tool, the overall strength of the tool can be ensured effectively, the sharpness of the tool is increased, and the service life of the tool is prolonged. When the aluminum piston ring slot tool is used for machining an aluminum piston ring slot, aluminum chips are broken uniformly along a designed chip breaking slot, and the broken aluminum chips are smoothly discharged out of the ring slot of a piston along the chip breaking slot of the tool. By adopting the aluminum piston ring slot tool, the problem of sticking of aluminum chips in the ring slot of the piston in a machining process can be effectively solved. Meanwhile, the surface machining quality of the ring slot of the piston can be well kept.
Description
Technical field
The utility model relates to the processing of a kind of cutter of non-ferrous metals processing, particularly all-aluminium piston, belongs to mechanical manufacturing field.
Background technology
Piston is one of important spare part of vehicle piston internal combustion engine.In order to ensure the premium properties of internal-combustion piston engine, the fit tolerance dimensional requirement of other accessory of piston and internal-combustion piston engine is very strict, especially the processing dimension of piston ring groove.The guarantee of the sealing property of the geomery of piston ring groove and position of related features combustion motor cylinder plays a part particular importance.
Aluminium alloy is one of main material of manufacturing in the piston of vehicle piston internal combustion engine.The toughness of material of the aluminium alloy that piston is used is relatively high, and in the time of fine finishining annular groove, in order to ensure the precision of annular groove, adopt less machine tool feed amount, cause in process aluminium bits do not allow easily broken fall, the meeting of part chip breaking is simultaneously stuck in manufactured annular groove the inside, cannot discharge from annular groove.Chip breaking difficulty can cause the speed that the crumb loading place of board is filled up to accelerate, and crumb loading place need repeatedly be cleared up timely, increases workman's the inefficient operation time.The phenomenon that aluminium bits are stuck in annular groove the inside is the intrinsic problem of Piston Machining industry.Complete system plant requires increasingly stringent, does not allow piston ring groove the inside to contain any aluminium bits.Therefore, piston manufacturer must examine entirely to the cleannes of piston ring groove.
Higher for the manufacture of Si content in the aluminium alloy of aluminium piston, use hard alloy cutter to carry out the machining of aluminium piston, tool wear is fast, and service life is low.At present, piston ring groove cutting process generally adopts and inlays PCD(polycrystalline diamond) blade carry out.The advantages such as it is high that PCD material has hardness, and wearability is good, and thermal conductivity is good, and coefficient of friction is low; Meanwhile, PCD material is hard and crisp, and current technical merit there is no method and use the chip-breaker of this materials processing complexity.
At present, general way is to increase chip breaking and the chip removal that the extra device such as chip-breaking and chip cleaner is considered to be worth doing to realize aluminium in the industry.
Summary of the invention
The purpose of this utility model is: in the situation that not using chip-breaking and piston ring groove chip removing device, by the Creative Design of cutter, make the aluminium bits that produce in piston ring groove process can be cut off smoothly and get rid of in time.
The utility model is for the fine finishining of aluminum piston ring groove.Cutter hub part of the present utility model adopts carbide alloy, the form that smear metal part takes to inlay PCD blade.The utility model comprises cutter hub, and the rake face of cutter hub is provided with a straightway face, is provided with the PCD blade of inclination certain angle on cutter hub.Cutter hub is provided with the chip curling groove of arc, and the PCD blade one end of inlaying connects cutter hub front end, and the other end connects the arc chip curling groove on cutter hub.The PCD blade being obliquely installed and the chip curling groove of arc have formed chip-breaker of the present utility model jointly, and this chip-breaker has good chip breaking and chip removal performance.In the time that cutter is fixed on Working position, the PCD blade that cutter hub is inlayed and processed piston center line out of plumb.Cutter hub of the present utility model is provided with the straightway plane of certain length on the rake face of main cutting edge, and on cutter hub, is provided with three sections of back angles.
Effect of the present utility model is: the aluminium that produces in process bits can become the chip breaking of C type easily, and C type chip breaking meeting is along with PCD knife face slides, and then passes through arc chip curling groove, under the effect of centrifugal force and be thrown out of outside annular groove.
Advantage of the present utility model is: only, by structural design and the optimization of cutter, can solve chip breaking difficult problem and chip removal difficult problem in Piston Machining annular groove process.

Detailed description of the invention
Cutter hub part of the present utility model adopts carbide alloy, the form that smear metal part takes to inlay PCD blade.
Cutter hub of the present utility model is provided with the straightway plane of certain length on the rake face of main cutting edge, and on cutter hub, is provided with three sections of back angle D1, D2 and D3.Straightway face on back angle D1 and rake face forms main cutting edge, and back angle D2 and back angle D3 can avoid cutter and work piece to produce interference.
The utility model comprises cutter hub, and the rake face of cutter hub is provided with a straightway face; On cutter hub, be provided with the PCD blade of inclination certain angle; Cutter hub is provided with arc chip curling groove C; The PCD blade E being obliquely installed and arc chip curling groove C have formed chip-breaker of the present utility model jointly, and this chip-breaker can ensure that process has good chip-breaking performance and chip removal performance.
