Abstract
The invention discloses a forming die for hexagon flange bolts with teeth. The forming die comprises an upper die and a lower die. An upper die core is arranged at the bottom of the upper die, a hexagonal die cavity and a flange inclined cavity which are communicated with each other are sequentially disposed in the upper die core, a lower die core is arranged in the lower die, a rod cavity, a rounding conical cavity, a tapping thread diameter cavity and a chamfering cavity which are communicated with each other are sequentially arranged in the lower die core, and a plurality of retaining grooves which are annularly arrayed are uniformly distributed on an end surface of the lower die core. The forming die in the scheme has the advantages that structures inside the upper die and the lower die are designed, machining process including turning and the like is omitted during machining, materials are saved, cost is reduced, the production speed of the die is fast, approximately 70pc of products can be produced every minutes, the production speed is increased by 7 times as compared with traditional production, production efficiency and precision are high, the inside of metal texture is changed when a metal material plastically deforms by the aid of the cold heading forming technology, mechanical performances of the products are improved, and the quality of the products is guaranteed.
Description
Technical field
The present invention relates to kind of a mould, relate in particular to a kind of hexagonal flange and wear tooth bolt mould.
Background technology
The hexagonal flange is worn the tooth bolt and is comprised bolt head, flange and bolt shank; Said flange bearing surface is provided with locking tooth, and bolt shank is provided with screw thread; Traditional technology through cold-heading coning after, utilize punch ram, trimming for forming; Need that the multiple tracks car is repaiied, the punch press manufacturing procedure, production process is various, and difficulty of processing is big; Can produce in one minute about 10pc, the production efficiency low quality can not guarantee, is in use broken easily.And turning process causes the raw material significant wastage, and cost is higher, and quality is also unstable.
Summary of the invention
Technical problem to above-mentioned existence the objective of the invention is: proposed the high and hexagonal flange that save material of a kind of production efficiency and worn tooth bolt mould.
Technical solution of the present invention is achieved in that a kind of hexagonal flange wears tooth bolt mould, comprises upper die and lower die, and said patrix bottom is provided with upper cores, in upper cores, is provided with the hexagonal die cavity, the flange beveled chamber that communicate successively; Be provided with down die in the said counterdie; Be provided with the bar portion shape chamber, turbination chamber, tapping shape chamber, footpath and the chamfering shape chamber that communicate in the said die down successively; Be uniformly distributed with the back stop slot of a plurality of circular array on the said die end face down.
Preferably, the inclined-plane angle in flange beveled chamber is 120 °～130 °.
Preferably, said back stop slot quantity is 39.
Preferably, said chamfering shape chamber angle is 50 °.
Preferably, said patrix outer wall is provided with steam vent.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
Hexagonal flange of the present invention is worn tooth bolt mould, through the cold-heading molding technology structure in patrix and the counterdie is designed, and makes the hexagonal flange wear the one-shot forming of tooth bolt; Exempt from processing technologys such as turning, practiced thrift material, reduced cost; And adopt this die production speed fast, and can produce about 70pc in one minute, compare traditional production and improved about 7 times; Production efficiency is high, and precision is high, and metal material generation plastic deformation changed metal structure inside when the cold-heading molding technology was; Improve mechanical performance of products, guaranteed product quality.
Description of drawings
Below in conjunction with accompanying drawing technical scheme of the present invention is described further:
Accompanying drawing 1 is worn patrix structural representation in the tooth bolt mould for a kind of hexagonal flange of the present invention;

The specific embodiment
Below in conjunction with accompanying drawing the present invention is described.
Accompanying drawing 1,2,3 is worn tooth bolt mould for a kind of hexagonal flange of the present invention, comprises patrix 1, counterdie 2, and said patrix 1 bottom is provided with upper cores 3, in upper cores 3, is provided with the hexagonal die cavity 5, the flange beveled chamber 6 that communicate successively; The inclined-plane angle in flange beveled chamber is 130 °; Be provided with down die 4 in the said counterdie 2; Be provided with the bar portion shape chamber 7, turbination chamber 8, tapping shape chamber 9, footpath and the chamfering shape chamber 10 that communicate in the said die 4 down successively; Said chamfering shape chamber angle is 50 °; Be laid with the back stop slot 11 of 39 circular array on the end face of said die 4 down; Said patrix 1 outer wall is provided with steam vent 12, and the heat that produces in patrix 1 course of work can in time be got rid of, and guarantees product quality.During mold work, workpiece 13 is taken out from a last station, put into counterdie shape chamber, from the top down it is carried out punching press through patrix again, make the workpiece bar that contracts mold the product that the die cavity shape is complementary.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
