Abstract
The invention discloses a sealing cover inner-outer flanging forming die which consists of an upper die part and a lower die part, wherein the upper die part consists of a punch die for the inner-outer flanging forming; the lower die part comprises a concave die, a convex die, an ejector and a lower template; the concave die is arranged on the lower template; a die hole matched with the convex die and the workpiece inner flanging is arranged in the concave die; the convex die is arranged in the die hole; the bottom end of the convex die is fixed on the lower template, and the upper end passes through the die hole and extends upward; and the ejector is arranged in the die hole and sleeved on the periphery of the convex die to cooperate with the punch die. The sealing cover inner-outer flanging forming die disclosed by the invention has a simple structure and is convenient to operate; and when in work, along with the downward moving of the punch die, a workpiece is subjected to one-step forming under the joint effect of the punch die, the concave die, the convex die and the ejector, the processing efficiency is high, the production cost is reduced, and great economic benefits are obtained.
Description
Technical field
The present invention relates to a kind of flanging molding die, relate in particular to a kind of inside and outside flanging molding die for seal cover production.
Background technology
In seal cover part processing as shown in Figure 1, blank is the round-disk shape workpiece with centre bore, processing this kind seal cover part needs this blank workpiece is carried out interior flanging, process takes to turn over first flanging 10 usually at present, after turn over the processing step of in-flanges 11, production efficiency is lower, can not satisfy the production requirement of part far away.
Summary of the invention
Technical problem for above-mentioned existence the objective of the invention is: proposed a kind of simple in structure, easy to operate, the inside and outside flanging molding die of the high one-shot forming seal cover of production efficiency.
Technical solution of the present invention is achieved in that the inside and outside flanging molding die of a kind of seal cover, and this mould is comprised of part of the upper die and part of the lower die, and described part of the upper die is comprised of the punch-die that is used for interior flanging moulding; Described part of the lower die comprises that die, punch, ejector and lower bolster form; Described die is arranged on the lower bolster, is provided with the nib suitable with described punch and workpiece in-flanges in the die; Described punch is arranged in the nib, and the bottom of punch is fixed on the lower bolster, and the upper end is passed nib and extended upward; Also be provided with ejector in the described nib, periphery and described punch-die that this ejector is set in punch are used; During work, along with described punch-die is descending, workpiece is finished the moulding of workpiece under the acting in conjunction of punch-die, die, punch and ejector.
Preferably, this mould also comprises push rod, and described push rod passes lower bolster and punch is connected on the ejector.
Because the utilization of technique scheme, the present invention compared with prior art has following advantages:
The inside and outside flanging molding die of a kind of seal cover of the present invention, simple in structure, easy to operate, during work, along with punch-die is descending, workpiece is under the acting in conjunction of punch-die, die, punch and ejector, workpiece is realized one-shot forming, working (machining) efficiency is high, reduces production costs, and obtains preferably economic benefit.

Accompanying drawing 2 is the structural representation of the inside and outside flanging molding die of a kind of seal cover of the present invention;
Wherein: 1, punch-die; 2, die; 3, ejector; 4, punch; 5, lower bolster; 6, nib; 7, push rod; 8, workpiece; 10, flanging; 11, in-flanges; 12, centre bore.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described.
Accompanying drawing 1 is the inside and outside flanging molding die shaping workpiece structure chart of a kind of seal cover of the present invention, and this workpiece comprises flanging 10, in-flanges 11 and centre bore 12.
Accompanying drawing 2 is the inside and outside flanging molding die of a kind of seal cover of the present invention, and this mould is comprised of part of the upper die and part of the lower die, and described part of the upper die is comprised of the punch-die 1 that is used for interior flanging moulding; Described part of the lower die comprises that die 2, ejector 3, punch 4 and lower bolster 5 form; Described die 2 is arranged on the lower bolster 5, is provided with the nib 6 suitable with described punch 4 and workpiece in-flanges in the die 2; Described punch 4 is arranged in the nib 6, and the bottom of punch 4 is fixed on the lower bolster 5, and the upper end is passed nib 6 and extended upward; Also be provided with ejector 3 in the described nib 6, periphery and described punch-die 1 that this ejector 3 is set in punch 4 are used; During work, blank is positioned on the punch 4, and by blank centre bore and punch 4 location, the part of the upper die is descending, punch-die 1 contact blank, and promote blank and rod jacking device 3 moves downward, punch-die 1 working portion is exerted pressure to each face of blank at this moment; Along with patrix continue descending, blank under the acting in conjunction of punch-die 1, die 2, punch 4 and ejector 3, one-shot forming workpiece 8.
Deviate from smoothly die 2 for assurance workpiece 8, this mould also comprises push rod 7, and described push rod 7 passes lower bolster 5 and is connected on the ejector 3 with punch 4, promotes ejectors 4 by push rod 7 and moves upward, and workpiece 8 is ejected from die 2.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics; its purpose is to allow the personage that is familiar with technique can understand content of the present invention and is implemented; can not limit protection scope of the present invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
