Description
Technical field
The utility model relates to a kind of cold upsetting die of car, is specifically related to a kind of bevel gear upsetting molding jig.
Background technology
In at present a lot of industry, particularly automobile industries, be applied to the bevel gear of small dimension much more especially, the preparation method of bevel gear is nothing more than machined or die cast processing at present, at the bottom of bevel gear working (machining) efficiency, the bevel gear process-cycle is long, and bevel gear manufacturing cost is high.
Summary of the invention
The deficiency existing for prior art, the purpose of this utility model is intended to provide a kind of can realize the bevel gear upsetting molding jig that bevel gear carries out cold-heading molding processing on cold-heading equipment.
The utility model is implemented by the following technical programs:
Bevel gear upsetting molding jig, comprise upper die and lower die, it is characterized in that: described patrix is provided with the upper shaping mold cavity on moulding bevel gear top, and described patrix is fixed on the bottom of upper bolster assembly, in upper bolster assembly, be provided with upper ejector pin, upper ejector pin is movable setting above upper shaping mold cavity, described counterdie is provided with the compacted under die cavity of moulding bevel gear bottom, described counterdie is actively installed in die shoe assembly, die shoe assembly comprises mould cylinder and annular voussoir, annular voussoir arranges between mould cylinder endoporus and counterdie cylindrical, annular voussoir cuts into identical some institutes by wedge shape annulus and forms, annular voussoir side be provided with spring eye, in spring eye, place little spring, the cylindrical of annular voussoir is provided with wedge surface, the inner circle of annular voussoir is provided with in conjunction with internal tooth, described mould cylinder endoporus is provided with wedge hole and mates with the wedge surface of annular voussoir, epimere wedge hole and hypomere wedge hole are divided in wedge hole, when the cylindrical of annular voussoir contacts with hypomere wedge hole, annular voussoir is annulus closure, when annular voussoir cylindrical contacts with epimere wedge hole, annular voussoir is annulus and opens under the effect of little spring, described upper die and lower die cylindrical is provided with and the combination external tooth mating in conjunction with internal tooth, annular the top end face of voussoir and the bottom surface of upper bolster assembly over against, the bottom end face of annular voussoir and secondary knock-pin over against, the bottom of described compacted under die cavity is provided with to lead and ejects hole, leads to eject in hole, to be movably equipped with main knock-pin.
The bevel gear upsetting molding jig of technique scheme, can realize bevel gear and on cold-heading equipment, directly carry out cold-heading molding processing, operation principle is: first blank is sent in the compacted under die cavity of counterdie, then patrix moves down, the bottom surface of patrix and the end face of counterdie are adjacent to, the bottom surface of while upper bolster assembly and the top end contact of annular voussoir promote annular voussoir and move down, annular voussoir from epimere wedge hole to the moving process in hypomere wedge hole, ring wedge BOB(beginning of block) annulus is closed, its combination external tooth in conjunction with internal tooth and upper and lower mould cylindrical fastens, upper and lower mould carries out matched moulds, next blank is shaped in airtight shaping mold cavity up and down, after shaping is over, along with moving on patrix, first by secondary knock-pin, annular voussoir is up pushed up upper and lower mould is opened, and then by main knock-pin, workpiece is ejected to compacted under die cavity.Because the utility model has been realized the cold-heading molding processing of bevel gear on cold-heading equipment, so greatly improved bevel gear working (machining) efficiency, shortened the bevel gear process-cycle, reduced bevel gear manufacturing cost.
Accompanying drawing explanation
The utility model has following accompanying drawing:
Fig. 1 is structural representation of the present utility model,
Fig. 2 is the bevel gear outline drawing of the utility model upsetting system.
The specific embodiment
As shown in Figure 1, bevel gear upsetting molding jig of the present utility model, comprise patrix 3 and counterdie 7, described patrix 3 is provided with the upper shaping mold cavity on moulding bevel gear top, described patrix 3 is fixed on the bottom of upper bolster assembly 2, in upper bolster assembly 2, be provided with upper ejector pin 1, upper ejector pin 1 is movable setting above upper shaping mold cavity, described counterdie 7 is provided with the compacted under die cavity of moulding bevel gear bottom, described counterdie 7 is actively installed in die shoe assembly, die shoe assembly comprises mould cylinder 4 and annular voussoir 5, annular voussoir 5 arranges between mould cylinder 4 endoporus and counterdie 7 cylindricals, annular voussoir 5 cuts into identical four institutes by wedge shape annulus and forms, the side of annular voussoir is provided with spring eye, in spring eye, place little spring 6, the cylindrical of annular voussoir 5 is provided with wedge surface, the inner circle of annular voussoir 5 is provided with in conjunction with internal tooth 10, described mould cylinder 4 endoporus are provided with wedge hole and mate with the wedge surface of annular voussoir 5, epimere wedge hole and hypomere wedge hole are divided in wedge hole, when the cylindrical of annular voussoir 5 contacts with hypomere wedge hole, annular voussoir 5 is annulus closure, when the cylindrical of annular voussoir 5 contacts with epimere wedge hole, annular voussoir 5 is annulus and opens under the effect of little spring 6, described patrix 3 and counterdie 7 cylindricals are provided with and the combination external tooth mating in conjunction with internal tooth 10, annular the top end face of voussoir 5 and the bottom surface of upper bolster assembly 2 over against, the bottom end face of annular voussoir 5 and secondary knock-pin 8 over against, the bottom of described compacted under die cavity is provided with to lead and ejects hole, leads to eject in hole, to be movably equipped with main knock-pin 9.
