Abstract
The utility model relates to a kind of mould structure forging tooth for spiral bevel gear bull wheel, comprise upper bolster (1), die shoe (2), upper punch (3), tooth mould (4), counterdie (5), low punch (6), lower push rod (7), low punch step surface (8) higher than pre-designed spiral bevel gear blanking inner hole (9) the upper surface 5-25mm forging tooth, upper punch (3) and low punch (6) guiding clearance monolateral be 0.2-0.8mm.The spiral bevel gear bull wheel blank overlap that the utility model forges, along back cone directional spreding, can be removed by postorder machining processes, without the need to bamboo product edger, improves stock utilization.
Description
Technical field
The utility model relates to a kind of mould structure forging tooth for spiral bevel gear bull wheel.
Background technology
The contour forging technique of current domestic conventional helical bevel gear tooth base fails to forge profile of tooth, and after mould therefor structure forges finished product, often there is larger radial overlap, this process materials utilization rate is low, also need to design special edger simultaneously, carry out forging rear trimming operation, which enhance the production cost of product.
Summary of the invention
The utility model provides the mould structure that spiral bevel gear bull wheel precision forging goes out tooth, and the spiral bevel gear bull wheel blank adopting this mould structure to forge does not need to carry out forging rear trimming operation.
The technical solution adopted in the utility model is: a kind of mould structure forging tooth for spiral bevel gear bull wheel, comprise upper bolster 1, die shoe 2, upper punch 3, tooth mould 4, counterdie 5, low punch 6, lower push rod 7, low punch step surface 8 higher than pre-designed spiral bevel gear blanking inner hole 9 upper surface (10) 5-25mm forging tooth, upper punch 2 and low punch 6 guiding clearance monolateral be 0.2-0.8mm.
Preferably, tooth mould 4 cylindrical is fitted with tooth mould circle stress 11.
Preferably, tooth mould 4 cylindrical and tooth mould circle stress 11 endoporus all have the tapering of 1-3 degree.
Preferably, the Step Shaft first half of low punch 6 is the conical surface.
Preferably, the endoporus of tooth mould 4 is the face of cylinder.
The beneficial effects of the utility model are:
1, the spiral bevel gear bull wheel blank overlap that forges of the utility model is along back cone directional spreding, can be removed by postorder machining processes, without the need to bamboo product edger, improves stock utilization;
2, the utility model has self-steering function, does not need the guiders such as specialized designs guide pillar guide pin bushing or snap close;
3, the utility model tooth mould outside has circle stress structure, can improve the service life of tooth mould.
Accompanying drawing explanation
Fig. 1 is assembling schematic diagram of the present utility model;
Fig. 2 is low punch step surface and plan positional relationship schematic diagram on the spiral bevel gear bull wheel blanking inner hole forging tooth.
In figure, 1. upper bolster, 2. die shoe, 3. upper punch, 4. counterdie, 5. tooth mould, 6. lower push rod, 7. low punch, 8. low punch step surface, the 9. pre-designed spiral bevel gear blank forging tooth, the 10. pre-designed spiral bevel gear blanking inner hole upper surface forging tooth, 11. tooth mould circle stresses.
Detailed description of the invention
The utility model can be used for the forging equipments such as electric screw press, friction press and numerical control electrohydraulic hammer.As shown in Figure 1 and Figure 2, a kind of mould structure forging tooth for spiral bevel gear bull wheel, comprise upper bolster 1, die shoe 2, upper punch 3, tooth mould 4, counterdie 5, low punch 6, lower push rod 7, low punch step surface 8 higher than pre-designed spiral bevel gear blanking inner hole 9 upper surface (10) 5-25mm forging tooth, upper punch 2 and low punch 6 guiding clearance monolateral be 0.2-0.8mm.
Preferably, tooth mould 4 cylindrical is fitted with tooth mould circle stress 11.
Preferably, tooth mould 4 cylindrical and tooth mould circle stress 11 endoporus all have the tapering of 1-3 degree.
Preferably, the Step Shaft first half of low punch 6 is the conical surface.
Preferably, the endoporus of tooth mould 4 is the face of cylinder.
The step surface of the utility model low punch is higher than the pre-designed spiral bevel gear blanking inner hole upper surface 5-25mm forging tooth, in forging process, excess stock can flow along gear back cone direction, avoids and flows thus formation flash of inner hole toward endoporus at blank forming process in which materials; When tooth mould touches precut blanks, the endoporus of upper punch and the Step Shaft of low punch play the guiding role, because guiding clearance is smaller, in order to lead smoothly, generally the Step Shaft first half of low punch is made the conical surface, such targeting part is realized by upper low punch, does not need the guiders such as specialized designs guide pillar guide pin bushing or snap close; Tooth mould outside has circle stress structure, and tooth mould and tooth mould circle stress adopt the mode of hot charging to assemble, and can improve the service life of tooth mould; When upper low punch beat by time and liftable patrix, at this moment lower push rod jack-up low punch, forging can be taken out.
Angle between the overlap in forging back cone direction and wheel blank axis is 2 °-20 °.When the cylindrical of spiral bevel gear bull wheel final products is the face of cylinder, then the angle can determining overlap and axis is 2 °-12 °; When the cylindrical of spiral bevel gear bull wheel final products is the intersecting point dimension that back cone and face cone intersect formation, then the angle can determining overlap and axis is 15 °-20 °.
