Abstract

The utility model relates to an inwards and outwards flanging forming die for a sealed cap. The inwards and outwards flanging forming die for the sealed cap is composed of an upper die part and a lower die part, wherein the upper die part is composed of a punch-die used for inwards and outwards flanging forming, and the lower die part is composed of a concave die, a terrace die, an ejector and a lower die plate. The concave die is arranged on the lower die plate. A die hole is formed in the concave die, wherein the die hole is matched with the terrace die and an inwards flanging edge of a workpiece. The terrace die is arranged in the die hole. The bottom end of the terrace die is fixed on the lower die plate. The upper end of the terrace die penetrates through the die hole and extends upwards. The ejector is further arranged in the die hole. The ejector is arranged on the periphery of the terrace die in a sleeved mode and can be used in cooperation with the punch-die. The inwards and outwards flanging forming die for the sealed cap is simple in structure and convenient to operate. When the inwards and outwards flanging forming die for the sealed cap is in working, along with the downward movement of the punch-die and under the collective action of the punch-die, the concave die, the terrace die and the ejector, once-forming of the workpiece is achieved. Machining efficiency is high, manufacture cost is reduced and good economic benefits are gained.

Description

The inside and outside flanging molding die of a kind of seal cover
Technical field
The utility model relates to a kind of flanging molding die, relates 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.
The utility model content
The utility model purpose is to provide a kind of simple in structure, easy to operate in order to overcome the deficiencies in the prior art, the inside and outside flanging molding die of the one-shot forming seal cover that production efficiency is high.
For achieving the above object, the technical solution adopted in the utility model is: 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 utility model compared with prior art has following advantages:
The inside and outside flanging molding die of a kind of seal cover of the utility model scheme, 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.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Accompanying drawing 1 is the inside and outside flanging molding die shaping workpiece structure chart of a kind of seal cover of the present utility model;
Accompanying drawing 2 is the structural representation of the inside and outside flanging molding die of a kind of seal cover of the present utility model;
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
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
Accompanying drawing 1 is the inside and outside flanging molding die shaping workpiece structure chart of a kind of seal cover of the present utility model, 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 described in the utility model, 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.
Below only be concrete exemplary applications of the present utility model, protection domain of the present 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.
