Abstract
The utility model discloses a hexagonal bolt head one-step molding mold, which comprises an upper mold and a lower mold. The upper mold is further connected with a punch, cavities in the shape of a bolt head and in the shape of a rod are formed on a mold core of the lower mold, a punch top end outer chamfer structure is formed on the periphery of the top end of the punch, the center of the top end of the punch is outwards convex to form a bolt head inner hexagonal structure, and a punch top end inner chamfer is disposed on the inner hexagon structure. The inner chamfer and the outer chamfer structure are disposed at the end of the punch so that a bolt head can be molded at one step when in punching, an inner chamfer, an outer chamfer and a head mark can be molded simultaneously, and then the hexagonal bolt head one-step molding mold is extremely convenient, reduces processing procedures, increases production efficiency, can not waste materials, and simultaneously guarantees quality of products.
Description
Technical field
The utility model relates to a kind of mould, particularly relates to a kind of one-time-shaped mould of inside and outside chamfering of standard component hexagonal king-bolt, belongs to the precision machinery technology field.
Background technology
Fig. 1 is traditional inside and outside chamfering shaping schematic view of bolt head.
As shown in Figure 1: the outer chamfering 1 of traditional hexagon bolt head and interior chamfering 2 all are to come out by lathe tool 3 turning of lathe, at first screw is fixed by special fixture, then with outer chamfering 1 part of lathe elder generation processing bolt head, interior chamfering 2 parts of tool changing processing bolt head again after outer chamfering 1 processes, like this processing not only time-consuming, take material, also increased processing cost, prolong the delivery period of product simultaneously, in addition, the leader of hexagon bolt head is to make out in the bundle bar, and its quality stability is very unreliable.
The utility model content
In order to overcome the deficiencies in the prior art, but the purpose of this utility model is to provide the hexagon bolt head one-time forming mold of the inside and outside chamfering of a kind of one-shot forming hex bolts simple in structure.
The utility model is achieved through the following technical solutions:
A kind of hexagon bolt head one-time forming mold, comprise upper die and lower die, wherein, also be connected with drift on the patrix, the mould heart of counterdie then is formed with the die cavity of bolt head and bar portion shape, it is characterized in that, chamfering structure outside drift top periphery forms the drift top, and centre, drift top forms the interior hexagonal structure of bolt head to outer lug, and interior hexagonal structure is provided with chamfering in the drift top.
Further, on the end face on described drift top, also be formed with the leader structure.
The beneficial effects of the utility model are: in the utility model is provided with by the end at drift chamfering and outside chamfering structure, make it when bolt head is carried out punching press, can be once with the bolt head moulding, chamfering and outer chamfering and leader in it of moulding simultaneously also, very convenient, reduced manufacturing procedure, improved production efficiency, and waste material has not also guaranteed the quality of product simultaneously.
Description of drawings
Fig. 1 is traditional inside and outside chamfering shaping schematic view of bolt head;
Fig. 2 is the structural representation of the utility model one embodiment;
Fig. 3 is the A portion enlarged drawing of Fig. 2.
Main Reference numeral implication is among the figure:
1, the outer chamfering 1 of bolt head ', the outer chamfering 2 on drift top, the interior chamfering of bolt head
2 ', the interior chamfering 3 on drift top, lathe tool 4, patrix
5, counterdie 6, drift 7, die cap
8, main mould 9, cushion block 0, hex bolts
The specific embodiment
Below in conjunction with accompanying drawing, describe the specific embodiment of the present utility model in detail:
Fig. 2 is the structural representation of the utility model one embodiment; Fig. 3 is the A portion enlarged drawing of Fig. 2.
As shown in Figures 2 and 3: hexagon bolt head one-time forming mold, comprise patrix 4 and counterdie 5, wherein, also be connected with drift 6 on the patrix 4, drift 6 drives by driver part and moves up and down, die cap 7 is contained at the mould heart position of counterdie 5, main mould 8 and cushion block 9, wherein, die cap 7, main mould 8 and cushion block 9 are provided with successively from the top down, be formed centrally the die cavity of bolt head shape in the die cap 7, the center of main mould 8 and cushion block 9 then is communicated as one, be formed with the die cavity of bolt shank shape, die cap 7, the center of main mould 8 and cushion block 9 forms the die cavity of hex bolts 0 shape jointly, form the outer chamfering 1 ' structure on drift top in drift 6 top peripheries, and centre, drift 6 top is to outer lug, form the interior hexagonal structure of bolt head, and interior hexagonal structure be provided with chamfering 2 in the drift top ', in addition, on the end face on drift top, also can be formed with the leader structure, this leader structure can get on the sign setting of needed hexagon socket head cap screw by electrode at the nose of punch of patrix, just leader can be got to the head of hexagon socket head cap screw when the hexagon socket head cap screw head one-time forming.
The pneumatic actuation parts, punch press is descending, and drift is descending thereupon, makes bolt moulding in the die cavity of the core rod of counterdie 5, simultaneously can disposable outer chamfering and the interior chamfering of bolt head and all one-shot formings of sign on the end face with bolt head.So promptly not fewly again during waste material reduce manufacturing procedure, improved the efficient of producing this series products.
Below disclose the utility model with preferred embodiment, so it is not in order to restriction the utility model, and all employings are equal to replaces or technical scheme that the equivalent transformation mode is obtained, all drops within the protection domain of the present utility model.
Claims (2)
1. hexagon bolt head one-time forming mold, comprise upper die and lower die, wherein, also be connected with drift on the patrix, the mould heart of counterdie then is formed with the die cavity of bolt head and bar portion shape, it is characterized in that, chamfering structure outside drift top periphery forms the drift top, and centre, drift top forms the interior hexagonal structure of bolt head to outer lug, and interior hexagonal structure is provided with chamfering in the drift top.
2. hexagon bolt head one-time forming mold according to claim 1 is characterized in that, also is formed with the leader structure on the end face on described drift top.
