Abstract
The utility model discloses a spinning forming die for semi-finished gears. The spinning forming die comprises an upper die and a lower die, as well as a thickening spinning wheel used together with the upper and lower die, and a forming spinning wheel, wherein a positioning column is mounted in the middle of the lower die, is in tight fit with the lower die, and is in clearance fit with the central hole of a gear blank piece; ring-shaped steps are arranged at corresponding parts of the outer sides of both the lower end surface of the upper die and the upper end surface of the lower die; and the shapes of the ring-shaped steps are matched with those of tooth-shaped parts of the semi-finished gears. The spinning forming die can greatly improve the production efficiency, the material utilization ratio and the performance of the gears.
Description
Technical field
The utility model relates to the technological equipment field, relates in particular to a kind of gear semi-finished product mould pressing mould.
Background technology
Gear is most popular mechanical transmission part in the industries such as aircraft, automobile, agricultural machinery, lathe, processing mode commonly used first adopts casting to make blank, again through car, mill, the gold such as mill cuts and is processed into the gear semi-finished product, then mill teeth, roll flute etc. are processed as finished product.Such processing mode manufacturing cycle is long, cost is high, and stock utilization is low.
Summary of the invention
For addressing the above problem, a kind of gear semi-finished product mould pressing mould of the present utility model, can be with the conglobate gear blank spare of sheet material punching for the thinner gear of transverse tooth thickness, be the gear blank spare outside that form of gear tooth position thickens, mechanical strength improves through spinning again, be processed into punching press or milling profile of tooth after the gear semi-finished product, thereby greatly enhance productivity and stock utilization.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of gear semi-finished product of the utility model mould pressing mould, comprise patrix, counterdie, and the spinning roller that thickens that is mated use, the shaping spinning roller, a locating dowel is installed in the middle part of described counterdie, described locating dowel and counterdie are tight fit, the centre bore of locating dowel and gear blank spare is for movingly, and described patrix lower surface is provided with ring-shaped step with corresponding position, the outside, described counterdie upper surface, and described ring-shaped step shape is mated with gear semi-finished product toothed section profile.
The utility model further improves and is: the described working face that thickens spinning roller is the circular groove face
The further improvement of the utility model also is: the working face of described shaping spinning roller is the face of cylinder, the half-finished toothed section thickness matching of face of cylinder height and gear.
The beneficial effects of the utility model are: can be the gear blank spare outside that form of gear tooth position thickens, mechanical strength improves, with car, mill, grind machining relatively production efficiency improve more than three times, stock utilization improves more than 20%, and intensity and the hardness of the tissue density of material, product surface all are significantly improved.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
In order to deepen that understanding of the present utility model is further described the utility model below in conjunction with embodiment and accompanying drawing, this embodiment only is used for explaining the utility model, does not consist of the restriction of the utility model protection domain.
as shown in Figure 1: a kind of gear semi-finished product mould pressing mould of the present utility model, comprise patrix 1, counterdie 2, and be mated use thicken spinning roller 5, shaping spinning roller 6, a locating dowel 3 is installed in middle part at counterdie 2, described locating dowel 3 is tight fit with counterdie 2, the centre bore of locating dowel 3 and gear blank spare 9 is for movingly, described patrix 1 lower surface is provided with ring-shaped step 4 with described counterdie 2 corresponding positions, the outside, upper surfaces, described ring-shaped step 4 shapes and gear semi-finished product toothed section profile coupling, the described working face that thickens spinning roller 5 is circular groove face 7, the working face of described shaping spinning roller 6 is the face of cylinder 8, the face of cylinder 8 height and the half-finished toothed section thickness matching of gear.
when the utility model is implemented, the operator is arranged on gear blank spare 9 on locating dowel 3, after patrix 1 clamps gear blank spare 9 with counterdie 2, spindle unit by the vertical spinning machine drives and fast rotational, thicken spinning roller 5 under the radial direction mechanism parts of vertical spinning machine drive along gear blank spare 9 radial feeds, make the 9 lateral step 4 continuous plastic deformations of top and bottom pointwise of gear blank spare and after thickening under the effect of arc groove face 7, thickening spinning roller withdraws from, gear blank spare 9 radial feeds of shaping spinning roller 6 after under the radial direction mechanism parts driving of vertical spinning machine, the edge thickens, be spun into the gear semi-finished product under 8 effects of the face of cylinder.
After the utility model is implemented, making the gear blank spare outside is that form of gear tooth position thickens, mechanical strength improves, with car, mill, grind machining relatively production efficiency improve more than three times, stock utilization improves more than 20%, and intensity and the hardness of the tissue density of material, product surface all are significantly improved.
