Abstract
The utility model relates to a pre-deforming piece mould for a hexagonal flange bolt. The pre-deforming piece mould for the hexagonal flange bolt comprises an upper module and a lower mould matched in use with the upper mould. The upper mould is internally provided with a mould cavity which is internally provided with a punching core in interference fit with the mould cavity. The mould cavity is further internally provided with a punching rod above the punching core. The punching core is internally provided with a segment cavity and a cone-shaped cavity communicated with the segment cavity. The lower mould comprises a lower mould shell, a mould piece, a lower mould core and a locking sleeve. The mould piece and the lower mould core are arranged in the lower mould shell sequentially. The lower mould core is locked in the lower mould shell through the locking sleeve. The mould piece is internally provided with a head cylindrical cavity. The lower mould cover is internally provided with a cone-shaped cavity and a long cylindrical cavity communicated with each other sequentially. According to the scheme provided by the utility model, the pre-deforming piece which can cause the subsequent hexagon heads and flanges to be stably deformed can be produced by using the mould. The pre-deforming piece can ensure that dissected hexagon heads are regular, an overlarge rounded corner is avoided at a hexagonal edge close to an end face, and the plate fastening height can be guaranteed.
Description
Technical field
The utility model relates to a kind of mould, relates in particular to a kind of hexagon flange bolt predeformation part mould.
Background technology
The hexagon flange bolt production method is earlier through to after biscuit blanking shaping and the predeformation, adopts crowded method of cutting be shaped turret head and flange face, and the predeformation part often becomes cone shape.After the predeformation part is made cone shape; Squeeze to squeeze when cutting turret head and cut mould and at first begin down to squeeze, squeeze and cut mould in the process and contact with blank that back metal quilt down excises, if the small end of blank is less than the hexagonal diagonal-size from the cone small end; Mould squeezes the position of cutting will be toward moving down; Contact with blank up to the hexagonal die orifice, the position that does not contact with mould just becomes big fillet, and part quality does not reach requirement.In addition, if the big end size of the cone shape of predeformation part if than the size of flange face cylindrical little too much, the flange face cylindrical that squeezes after cutting does not just reach requirement, the bottom that can occur plum blossom shape overlap after the side cut is not excised, and forms the hexagonal breach.The sex change part excises the plum blossom overlap subsequently again through the crowded overlap of cutting back formation plum blossom shape at flange face cylindrical place in advance, so material consumption increases, stock utilization reduces and the part quality instability.
The utility model content
The utility model purpose is for the deficiency that overcomes prior art a kind of hexagon flange bolt predeformation part mould to be provided, and can produce a kind of predeformation part through this mould, and this predeformation part can guarantee postorder turret head, flange steady-state deformation moulding.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of hexagon flange bolt predeformation part mould, comprise patrix, with the counterdie that patrix is used, be provided with die cavity in the patrix, be provided with the benevolence of dashing in the die cavity with the die cavity interference fit; Also be provided with the rod that dashes that is positioned at towards the benevolence top in the said die cavity; The said conical cavity that is provided with segment shape chamber and communicates in the benevolence with segment shape chamber; Said counterdie comprises formwork, matrix, following die and lock tube down; Said matrix, following die are successively set on down in the formwork; Said die down is locked at down in the formwork through lock tube; Be provided with the head cylindrical cavity in the said matrix; Be provided with the cone shape chamber that communicates successively, cylinders bodily form chamber in the die under said.
Preferably, in benevolence, also be provided with slotted hole, said slotted hole communicates with segment shape chamber.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
A kind of hexagon flange bolt predeformation part mould of the utility model scheme; Can produce the predeformation part that send as an envoy to postorder turret head and flange can steady-state deformations through this mould; This predeformation part can guarantee to squeeze the turret head rule after cutting; The hexagonal corner angle avoid occurring excessive fillet by the end, guarantee the stubborn height of plate.
Description of drawings
Below in conjunction with accompanying drawing the utility model technical scheme is described further:
Accompanying drawing 1 is the structural representation of a kind of hexagon flange bolt predeformation part mould of the utility model;
The predeformation part structural representation that accompanying drawing 2 goes out for a kind of hexagon flange bolt predeformation part Mould Machining of the utility model;
Wherein: 1, patrix; 2, counterdie; 3, die cavity; 4, towards benevolence; 5, dash rod; 6, segment shape chamber; 7, conical cavity; 8, following formwork; 9, matrix; 10, following die; 11, lock tube; 12, head cylindrical cavity; 13, cone shape chamber; 14, cylinders bodily form chamber; 15, slotted hole.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
Accompanying drawing 1,2 is the described a kind of hexagon flange bolt predeformation part mould of the utility model, and the counterdie 2 that comprises patrix 1, is used with patrix 1 is provided with die cavity 3 in the patrix 1, be provided with in the die cavity 3 with die cavity 3 interference fit dash benevolence 4; Also be provided with in the said die cavity 3 be positioned at towards benevolence 4 tops dash the rod 5; The said conical cavity 7 that is provided with segment shape chamber 6 and communicates in the benevolence 4 with segment shape chamber 6; Said counterdie 2 comprises formwork 8, matrix 9, following die 10 and lock tube 11 down; Said matrix 9, die 10 is successively set on down in the formwork 8 down; Said die 10 down is locked at down in the formwork 8 through lock tube 11; Be provided with head cylindrical cavity 12 in the said matrix 9; Be provided with the cone shape chamber 13 that communicates successively, cylinders bodily form chamber 14 in the die 10 under said; In benevolence, also be provided with the slotted hole 15 that communicates with segment shape chamber.
Below only be the concrete exemplary applications of the utility model, the protection domain of the utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, all drop within the utility model rights protection scope.
