Description
Technical field
The utility model relates to a kind of improvement of coiling tooth class blank forging method, a kind ofly specifically coil the forging mould of tooth class blank with the many forgings of a machine, be applicable to be arranged on the rough forging of forging dish tooth class on electric screw press, base and shapingly simultaneously to carry out, once can process two pieces blank.
Background technology
General employing electric screw press forging dish tooth class and axle tooth class blank, as Figure 16, be the cross-sectional shape of first speed driven gear: 305N5-37105AMP at present; Mould adopts upper and lower compound open die, and electric screw press to be provided with on forcing press frock under frock and forcing press, and patrix is fixed on forcing press bottom frock by top board, and counterdie is fixed on frock top under forcing press by lower platen; Described patrix is made up of patrix positioning boss, upper mould body and patrix guide ledges, patrix positioning boss is fixedly installed on the top of mould body, suitable with frock on forcing press, patrix guide ledges is located at the bottom of mould body, and the middle part of patrix guide ledges is provided with a upper die head; Described counterdie is made up of lower mould body, counterdie positioning boss and counterdie direction recess, counterdie positioning boss is fixedly installed on the bottom of lower mould body, suitable with frock under forcing press, the top of lower mould body is provided with the counterdie direction recess suitable with patrix guide ledges, the lower mode cavity suitable with upper die head is provided with at the middle part of counterdie direction recess, the lower mould body of the center of lower mode cavity is provided with material returned jogger hole, and upper die head and lower mode cavity are all suitable with the shape of first speed driven gear: 305N5-37105AMP.Its production method is: (1), choose bar: the bar of diameter 70; (2), blanking: take sawing machine blanking, cutting stock weight 2.6Kg; (3), heat, adopt middle frequency furnace, heat induced boiler tube single-piece discharging formula; (4) pneumatic hammer of, base: 250Kg, upper and lower planar aerial tup pneumatic hammer is equipped with, the bar heated is placed in pneumatic hammer lower ram plane, operative employee pulls pneumatic hammer to hit action bars back and forth, upper ram hits the bar on lower ram, bar is hit about diameter about the 118mm of thickness, because not hitting bottom dead centre when pneumatic hammer hits, made blank dimension only has and operates by the eyesight of operative employee, the weight of action bars and experience, and thickness and the diameter of base differ, directly affects the product quality of shaping link; (5), forge shaping: adopt 1000T electric screw press (single-piece forges method); (6), trimming: because pneumatic hammer base is irregular, forge mould and cannot adopt enclosed non-trimming mould, take open type to have overlap mould only, 160T punch press must be adopted to be cut away by unnecessary burr after causing forging; (7), punching, the forging forged out is put into punching machine lower mold chamber, click punch press stroke switch, when punch press hits, penetrate forging centre by upper punch, by die-cut for excess stock in the middle of forging.Its process mould weak point is: when adopting this frock explained hereafter flow process production lot forging, 1, must a pneumatic hammer base flow process be increased more, and base is irregular, has a strong impact on follow-up finish-forging product quality; 2, because base effect is undesirable, finish-forging die can only take open die, and forging can produce burr, can only increase a punch press trimming flow process more; 3, often hit and once can only forge a forging blank, per tour normally produces about about 2500, and class's output is not high, and efficiency is low, flow process is more, technique is loaded down with trivial details, it is too many to occupy workman, and production cost remains high.
