Abstract
The utility model discloses a forming mould for a car steering wheel bolt, which comprises an upper plum-blossom punch needle, an upper punch jacking sleeve, an upper punch-die sleeve, an upper punch thimble sleeve, an upper punch thimble pad, a jacking pin, a jacking pin pad, a lower mould core and a lower mould thimble, wherein the quincunx physical dimension of an upper punch thimble is the required inner twelve-corner quincunx size of products; the upper punch thimble is excellently matched with an upper mould jacking sleeve, so as to ensure that the upper mould jacking sleeve can freely move and the upper punch thimble can be accurately positioned; and the lower mould core is made of hard alloy materials. By using the forming mould, the inner twelve-corner quincunx with required depth can be formed in cold heading manner, the punching head is prevented from being broken, and the damage to the mould, because the quincunx is formed again and the product is not dropped off in time when the product is pulled out and the punching head is retreated, is avoided. The working efficiency is greatly increased, the waste of raw materials is reduced, the inner fiber of metal is not changed by the cold heading of the deeper twelve-corner quincunx, the excellent metal streamline is acquired, and the quality of the products can be ensured.
Description
Technical field
The utility model relates to a kind of cold-heading mould, relates in particular to a kind of car steering wheel bolt forming mould.
Background technology
Advanced several years, the automobile manufacture industry of China develops rapidly, and its production technology and kind requirement to all kinds of automobile securing members is more and more higher, especially also needs a large amount of nonstandard products to adapt to the needs of industry development.As certain car steering wheel bolt, its head has the through hole of an interior plum blossom driving and a φ 9.6, and the car steering wheel passes this product, and the car steering wheel can not be pulled out after the bolting; Common heading portion of head elder generation for this series products, but plum blossom this processing technology existed certain defective in plum blossom preform hole was gone out again in getting out on the machined lathe then, because this metal material can destroy the machine direction of metal inside even destroy metallic crystalline structure after removing material through machined, thereby the mechanical property and the plastic deformation performances such as intensity, rigidity of metal product have been reduced.So this kind processing method, inefficiency, waste of raw materials is serious, influences product quality.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of car steering wheel bolt mould of cold upset forming.
For solving the problems of the technologies described above, a kind of car steering wheel of the utility model bolt mould comprises no-float upper punch ejector sleeve and last plum blossom towards pin and last ejecting structure, describedly goes up plum blossom and towards needle set interior quincunx with the shape of product coupling is arranged.
Described car steering wheel bolt mould, it also comprises the upper punch ejector sleeve.Because the utility model car steering wheel bolt mould upper punch thimble is quincunx and the interior plum blossom appearance and size of the car steering wheel bolt of required processing is complementary, make this mould can process required car steering wheel bolt easily, the plum blossom pre-manufactured hole is not realized the bolt size in not needing to bore with machined again, and the life-span of this mould reaches tens thousand of workpieces, therefore use this Mould Machining car steering wheel bolt, the product percent of pass height has improved work efficiency greatly, has improved product quality.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments:
Fig. 1 is the structural representation of the utility model car steering wheel bolt mould product two operations,
The specific embodiment
From Fig. 1 as seen, this special-purpose this mould of steering wheel bolt mould comprises that plum blossom is towards pin, 2 upper punch ejector sleeves, 3 upper punch die sleeves, 4 upper punch tailstock barrels, 5 upper punch thimble pads, 6 knock pins, 7 knock pin pads and 8 lower mold core and 9 counterdie thimbles on 1, and the quincunx physical dimension of upper punch thimble is exactly 12 jiaos of plum blossom sizes in the product requirement.
Finish the special-purpose steering wheel bolt of car two station production processes from top to bottom.
Claims (2)
1. car steering wheel bolt mould comprises that no-float upper punch ejector sleeve and last plum blossom towards pin and last ejecting structure, is characterized in that: describedly go up plum blossom and towards needle set interior quincunx with the shape of product coupling arranged.
2. car steering wheel bolt mould according to claim 1 is characterized in that it also comprises the upper punch ejector sleeve.
