Abstract
The utility model discloses a hot forming mold of a spiral bevel gear. The hot forming mold comprises an upper mold punch, a lower mold punch, metal powder, a mold core and a female mold cavity, an electric heating sleeve is sheathed on the outer wall of the lower end of the lower mold punch, and a heat-insulating jacket is arranged on the outer wall of the electric heating sleeve; the lower end of the upper mold punch is attached to the inner wall of the lower mold punch, the upper end of the lower mold punch is locked into the female mold cavity, and a temperature sensor is arranged in the side wall of the female mold cavity; and the metal powder is arranged between the bottom of the upper mold punch and the lower mold punch, and the mold core is arranged in the mold cavity of the upper mold punch. According to the hot forming mold of the spiral bevel gear, the metal powder is evenly spread in a tooth spacelots by adopting an internal expansion type forming mode and is heated in the tooth spaceslot, so the metal powder is evenly hot-molten and formed, and the positive and negative sides of spiral teeth can be evenly stressed and have the consistent density. Not only can the service life of the mold be prolonged, but also pressure can be saved.
Description
Technical field
The utility model relates to a kind of gear forming mould, is specifically related to a kind of spiral bevel gear hot briquetting mould.
Background technology
Spiral bevel gear be a kind of can high speed, high pulling torque, low noise ground be at the machine driving class part of not parallel between centers transmission campaign and power.Current spiral bevel gear is all the cylindrical screw gear, adopts and uses at normal temperatures bottom punch, to cavity space, metal dust is carried out to machine-shaping to the forming method of pressing.Because easily cause the just negative unbalance stress of helical tooth, easily cause the damage of mould in this moulding process, die life is short, and the pressure loss is serious.
Along with the continuous progress of science and technology, increasing field need to adopt spiral bevel gear, and especially helical angle surpasses 20
.the demand of circular cone very large.But being washed into the type method, traditional upper and lower mould can't process qualified spiral bevel gear, even produce reluctantly product, and its overload, acceleration, the performance such as durable is also very poor, does not reach application target.
So, how to produce qualified spiral bevel gear, make the just negative stressed even of helical tooth, the long service life of mould, oneself becomes the task of top priority in spiral bevel gear mould field.
The utility model content
The purpose of this utility model is to overcome the defect existed in prior art, provides the just negative stressed of a kind of helical tooth evenly can improve the quality of products, and can extend again the long spiral bevel gear hot briquetting mould of die life.
For achieving the above object, the technical solution of the utility model is a kind of spiral bevel gear hot briquetting mould of design, it is characterized in that, described hot briquetting mould comprises upper punch, bottom punch, metal dust, core rod and cavity space, be set with the electrical heating sleeve pipe on the outer wall of bottom punch lower end, on the outer wall of electrical heating sleeve pipe, be provided with heat insulation sheath; The lower end of upper punch is close on the inwall of bottom punch, and the upper end of bottom punch locks onto in cavity space, in the sidewall of cavity space, is provided with temperature sensor; Be provided with metal dust between the bottom of upper punch and bottom punch, in the die cavity of upper punch, be provided with core rod.
Wherein preferred technical scheme is that described bottom punch is structure wide at the top and narrow at the bottom, the outer wall of upper punch structure wide at the top and narrow at the bottom.
Advantage of the present utility model and beneficial effect are: this spiral bevel gear hot briquetting mould is to adopt the internal expansion type molding mode, make metal dust be expanded to uniformly among teeth groove, and heated in groove, that metal dust obtains uniform hot melt shaping, can make the just negative stressed even of helical tooth, consistent in density simultaneously.Both extend die life, saved again pressure.The utility model is mainly used in helical angle and surpasses 20
.the moulding of trochoid spiral angular wheel.
The accompanying drawing explanation
Fig. 1 is the structural representation of the utility model spiral bevel gear hot briquetting mould.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is further described.Following examples are only for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1, the utility model is a kind of spiral bevel gear hot briquetting mould, this hot briquetting mould comprises upper punch 1, bottom punch 2, metal dust 3, core rod 4 and cavity space 5, be set with electrical heating sleeve pipe 6 on the outer wall of bottom punch 2 lower ends, be provided with heat insulation sheath 7 on the outer wall of electrical heating sleeve pipe 6; The lower end of upper punch 1 is close on the inwall of bottom punch 2, and the upper end of bottom punch 2 locks onto in cavity space 5, is provided with temperature sensor 8 in the sidewall of cavity space 5; Be provided with metal dust 3 between the bottom of upper punch 1 and bottom punch 2, be provided with core rod 4 in the die cavity of upper punch 1.
In the utility model, preferred embodiment is that described bottom punch 2 is structure wide at the top and narrow at the bottom, the outer wall of upper punch 1 structure wide at the top and narrow at the bottom.
In the utility model, the manufacture method of spiral bevel gear mould is: first the lower end of upper punch 1 is inserted in bottom punch 2, add metal dust 3 between the bottom of upper punch l and bottom punch 2, then bottom punch 2 is locked onto in cavity space 5, core rod 4 is set in the die cavity of upper punch l again, be set with the heating muff 6 that powers on the outer wall of bottom punch 2 lower ends, be provided with heat insulation sheath 7 on the outer wall of electrical heating sleeve pipe 6, before punching press, first bottom punch 2 is heated, by the temperature sensor 8 test heating-up temperatures in the sidewall that is arranged on cavity space 5, and there is temperature-control circuit to control the heating-up temperature of electrical heating sleeve pipe 6.
The utility model adopts the molding mode of internal expansion type heated type, and metal dust is expanded among teeth groove uniformly, can make the just negative stressed even of helical tooth, institutional framework consistent in density by heating simultaneously.Both extend die life, saved again pressure.The utility model is mainly used in helical angle and surpasses 20
.the moulding of trochoid spiral angular wheel.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
