Abstract
The utility model discloses a special riveting pressure bolt mould, comprising an upsetting lower mould and an ejection pin. A through hole is arranged at the center of the upsetting lower mould and the ejection pin can have right-left movements inside the through hole of the upsetting lower mould. A mould sheet with an inner straight tooth is connected with the front end of the upsetting lower mould. The inner hole diameter and the tooth pitch of the mould sheet are matched with the straight tooth of the special riveting pressure bolt which needs to be machined. Because the mould sheet with an inner straight tooth is connected with the upsetting lower mould in the utility model, the special riveting pressure bolt is conveniently machined by the mould without using the hobbing machine to process the straight tooth machining; ten thousands of work pieces can be machined during the service life of the mould sheet with the straight tooth. The product qualification ratio becomes high if the utility model is used to machine the special riveting pressure bolt, improving the work efficiency greatly and the service life of the mould.
Description
Technical field
The utility model relates to a kind of mould, relates in particular to a kind of special-purpose riveting 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 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 the special-purpose riveting bolt of certain car, one section short straight-tooth is arranged under its head, it mainly uses on stamping parts of automobile.By to the distortion of straight-tooth riveting, make to be bolted on the assembly; Usually go out short cylindrical straight-tooth base for the first upsetting of short straight-tooth on this series products, on screw-rolling machine, roll out straight burr then.But this processing technology exists certain defective, because this product straight-tooth length is too short, thereby when rolling straight-tooth, product is very easily scurried out from cylindrical die roll, cause the straight-tooth size to be difficult to control and cause product rejection, therefore the full short cylindrical straight-tooth base because upsetting in advance is shaped in addition can shorten life-span of mould, several thousand products of general production, mould has just been scrapped; So this kind processing method, the percent defective height, inefficiency, die life is short.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of product passing rate of processing height, improves long special-purpose riveting bolt mould of work efficiency and die life
For solving the problems of the technologies described above, special-purpose riveting bolt mould of the present utility model, but comprise that the center has the upset counterdie of through hole and the knock pin of move left and right in upset counterdie central through hole, the matrix of straight-tooth in the front end of upset counterdie also is connected with band, the straight-tooth of the special-purpose riveting bolt of the internal orifice dimension of this matrix and tooth pitch and required processing is complementary; The upset counterdie is connected by hot pressing with the interior straight-tooth matrix of band; Knock pin becomes movingly with described upset counterdie; The straight-tooth matrix adopts Hardmetal materials in upset counterdie and the band.
Because the special-purpose riveting bolt of the utility model mould will be connected to the upset counterdie with the matrix of interior straight-tooth, make this mould can process required special-purpose riveting bolt easily, do not need to have realized the processing of straight-tooth with gear-hobbing machine again, and the life-span of straight-tooth matrix reaches tens thousand of workpieces in this band, therefore use the special-purpose riveting bolt of this Mould Machining, the product percent of pass height has improved work efficiency greatly, has improved die life.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments:
Fig. 1 is the structural representation before the processing of the special-purpose riveting bolt of the utility model mould product,
Fig. 2 is the structural representation after the processing of the special-purpose riveting bolt of the utility model mould product.
The specific embodiment
Fig. 1 is the structural representation before the processing of the special-purpose riveting bolt of the utility model mould product, this special-purpose riveting bolt mould comprises that the center has the upset counterdie 2 and the knock pin in upset counterdie 23 of through hole, but this knock pin 3 move left and right in the central through hole of upset counterdie 2, to eject the workpiece of cold-heading molding, the matrix 1 of straight-tooth in the front end of upset counterdie 2 also is connected with band, the internal orifice dimension of this matrix 1 and tooth pitch are complementary with the straight-tooth of the special-purpose riveting bolt that need are processed; Straight-tooth matrix 1 is connected by hot pressing in upset counterdie 2 and the band; 2 one-tenth of knock pin 3 and upset counterdies are movingly; Straight-tooth matrix 1 adopts Hardmetal materials in upset counterdie 2 and the band, and upper trimming die 4 pushing tow workpiece 5 enter mould.
Fig. 2 is the structural representation after the processing of the special-purpose riveting bolt of the utility model mould product, after upper trimming die 4 pushing tow workpiece 5 entered mould, workpiece 5 cold-heading moldings, upper trimming die 4 retreated and pushing tow knock pin 3, eject the workpiece 5 of cold-heading molding, so far finish the production process of special-purpose riveting bolt.
Claims (5)
