Description
Technical field
The present invention relates to a kind of blade of processing the valve retainer conical surface.
Background technology
Cylinder covers the position that fits with valve-face and is called valve seating, and the temperature during valve seating work is very high, bears the shock loading of very high frequency again, easily wearing and tearing.Therefore, aluminium cylinder lid and most of cast-iron head are all inlayed the valve retainer of being made by alloy cast iron or powder metallurgy or austenitic steel, on cylinder head, inlay valve retainer and can prolong the service life of cylinder head, also there are some cast-iron heads not inlay valve retainer, directly on cylinder head, process.Because the influence of the difference of seat ring material and the working environment of seat ring, the crudy of seat ring requires also very high.
In the actual processing of the engine seat ring conical surface, the reasonable coupling of cutter and use must be paid attention to, because the materials variances of seat ring, can directly have influence on the otherness of final machining status, so selecting rational process tool just to can be ensuing processing creates conditions, otherwise, then directly have influence on the quality of final processing, therefore, process tool is to the crudy important influence of process and workpiece, rationally use the relevant parameter of process tool, select suitable process tool, can realize better product quality.
Summary of the invention
The invention provides a kind of blade of processing the valve retainer conical surface, guarantee the convenient and swift high-speed cutting of blade, prolonged the life-span of blade, and change conveniently the machining accuracy height.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme: the blade of the processing valve retainer conical surface, comprise foursquare blade body, the front side of blade body is provided with one deck cutting tip, and cutting tip is that the material of monolithic construction and employing is a polycrystalline cubic boron nitride; The center of blade is provided with the clamping hole along the blade thickness direction, the clamping hole is divided into leading portion clamping hole, clamping hole, stage casing and back segment clamping hole, leading portion clamping hole is positioned at cutting tip, clamping hole, stage casing and back segment clamping hole are positioned at blade body, leading portion clamping hole and back segment clamping hole are the diameter of the diameter in cylindrical structural and leading portion clamping hole greater than back segment clamping hole, and clamping hole, stage casing is flaring curved-surface structure for transition portion and the clamping hole, stage casing that connects leading portion clamping hole and back segment clamping hole.
The side on four limits of described blade is equipped with 11 ° relief angle
Four angles of described blade are arcuate structure.
Described clamping hole adopts Laser Processing to form.
The present invention is simple in structure, and the function practicality guarantees the convenient and swift high-speed cutting of blade, has prolonged the life-span of blade, and practical all very convenient with replacing, the machining accuracy height.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is a vertical section structure schematic diagram of the present invention.
The specific embodiment
Embodiment: shown in Fig. 1-2, the blade of the processing valve retainer conical surface comprises foursquare blade body 1, and the front side of blade body 1 is provided with one deck cutting tip 2, and cutting tip 2 is a polycrystalline cubic boron nitride for the material of monolithic construction and employing; The center of blade is provided with clamping hole 3 along the blade thickness direction, clamping hole 3 is divided into leading portion clamping hole 6, clamping hole, stage casing 5 and back segment clamping hole 4, leading portion clamping hole 6 is positioned at cutting tip 2, clamping hole, stage casing 5 and back segment clamping hole 4 are positioned at blade body 1, leading portion clamping hole 6 and back segment clamping hole 4 are the diameter of the diameter in cylindrical structural and leading portion clamping hole 6 greater than back segment clamping hole 4, clamping hole, stage casing 5 is flaring curved-surface structure for transition portion and the clamping hole, stage casing 5 that connects leading portion clamping hole 6 and back segment clamping hole 4, and clamping hole 3 adopts Laser Processing to form.It is 11 ° relief angle that the side on four limits of blade is equipped with α.Four angles of blade are arcuate structure.
Blade of the present invention is four sword structures, improved the service life of blade, reduced tool change time, original single dege blade instability, be prone to tipping and damage, whole blade is scrapped after single-blade tipping or damage, works on and can change other blades after one of them blade damages now, for work guarantee normally is provided, improve four to five times the service life of blade.
The cutting tip narrow width of tradition single dege blade welding, littler behind the cutting inclination angle, like this can be because the influence of solder technology cause blade strength not enough, stability is not enough, tipping in use can occur or turn around to cause cutter to scrap.
Because polycrystalline cubic boron nitride (PCBN) hard high-wearing feature, difficult processing, and blade working position (the seat ring conical surface) requires the machining accuracy height, the PCBN(polycrystalline cubic boron nitride that this just requires us to process) blade has very high precision, so the employing Laser Processing.
Especially the processing in clamping hole on the blade, because its required precision height, overall precisions such as axiality, the depth of parallelism, perpendicularity must guarantee in certain limit.And the position of circular arc increasing difficulty of processing, make the difficult assurance of machining accuracy.Adopt Laser Processing, can address the above problem well.
