Abstract
The utility model discloses a battery steel shell molding and reshaping compound die and is applied to the technical field of manufacture of thin-wall battery steel shells. The battery steel shell molding and reshaping compound die comprises a reshaping concave die and a molding concave die, wherein the molding concave die is arranged on the upper end face of the reshaping concave die, a molding boss which surrounds the inner wall of the molding concave die by one circle is arranged at the upper opening end of the molding concave die in an extending mode, a reshaping boss which surrounds the inner wall of the reshaping concave die by one circle is arranged at the upper opening end of the reshaping concave die in the extending mode, and the diameter of the reshaping boss is smaller than that of the molding boss. Due to the fact that the concave dies in molding and reshaping are compounded to a pair of lower dies which can simultaneously achieve the molding and the reshaping by one pulling, the battery steel shell molding and reshaping compound die has the advantages of reducing process steps, simplifying die structure, saving die cost and improving production efficiency.
Description
Technical field
The utility model relates to a kind of thin wall battery shell production mould, especially relates to a kind of battery steel shell moulding, shaping compound die.
Background technology
At present, during in the end one (moulding) stretching of general thin wall battery box hat, thick inconsistent of thick and wall section material due to upper one process part processing bottom material, after the one-off drawing moulding, the external diameter at 3～5mm place, box hat bottom tends to than the large 0.02～0.03mm of body part external diameter, causes the bottom external diameter overproof.
See also illustrated in figures 1 and 2ly, Fig. 1 is the schematic diagram of the shaping step of traditional thin wall battery box hat, and Fig. 2 is the schematic diagram of the shaping work step of traditional thin wall battery box hat.Traditional solution is all in the shaping step back, then sets up the shaping work step one.The internal diameter of shaping counterdie is set to the left and right than the little 0.02mm of compact dimensions, makes the bottom of box hat remake the stretching of a 5～8mm in this size, thereby corrects the dimension overproof of this part.
Obvious, traditional solution exists work step more, and mould structure is complicated, the shortcoming that die cost is high and production efficiency is low.
The utility model content
The purpose of this utility model is to provide a kind of battery steel shell moulding, shaping compound die, it has the advantages that work step is few, mould structure is simple, cost is low and production efficiency is high, to solve the problem that in prior art, the thin wall battery box hat in the end stretches and exists together.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of battery steel shell moulding, shaping compound die, it comprises correcting die and molding concave die, wherein, the recessed film of described moulding is arranged on the upper surface of correcting die, the upper open end of described molding concave die is extended with the moulding boss around its inwall one circle, the upper open end of described correcting die is extended with the shaping boss around its inwall one circle, and the diameter of described shaping boss is less than the diameter of moulding boss.
Especially, the upper open end of described molding concave die offers the step surface around its inwall one circle, is fixed with a hard alloy profiled member on described step surface, elongation moulding boss on described hard alloy profiled member.
Especially, the upper open end of described correcting die offers the step surface around its inwall one circle, is fixed with a hard alloy shaping piece on described step surface, extends the shaping boss on described hard alloy shaping piece.
Especially, described moulding boss and shaping boss are the smooth surface structure.
The beneficial effects of the utility model are that described battery steel shell moulding, shaping compound die compared with prior art with the die of moulding and two work steps of shaping, are combined into a secondary counterdie, make one-off drawing just can complete simultaneously moulding and shaping two procedures.Thereby reduced work step, simplified mould structure, saved die cost, improved again production efficiency.
Description of drawings
Fig. 1 is the schematic diagram of the shaping step of traditional thin wall battery box hat,
Fig. 2 is the schematic diagram of the shaping work step of traditional thin wall battery box hat.
Fig. 3 is the battery steel shell moulding that provides of the utility model specific embodiment 1, the structural representation of shaping compound die.
The specific embodiment
Further illustrate the technical solution of the utility model below in conjunction with accompanying drawing and by the specific embodiment.
See also shown in Figure 3ly, Fig. 3 is the battery steel shell moulding that provides of the utility model specific embodiment 1, the structural representation of shaping compound die.
In the present embodiment, a kind of battery steel shell moulding, shaping compound die comprise correcting die 1 and molding concave die 2, the recessed film 2 of described moulding is arranged on the upper surface of correcting die 1, the openend of described molding concave die 2 offers the step surface around its inwall one circle, be fixed with a hard alloy profiled member 3 on described step surface, elongation moulding boss 4 on described hard alloy profiled member 3.The openend of described correcting die 1 offers the step surface around its inwall one circle, be fixed with a hard alloy shaping piece 5 on described step surface, extend shaping boss 6 on described hard alloy shaping piece 5, and the diameter of described shaping boss 6 is 17.98 ㎜, the diameter of described moulding boss 4 is 18 ㎜, and described moulding boss 4 and shaping boss 6 are the smooth surface structure.
Above-mentioned battery steel shell moulding, shaping compound die have not only reduced work step, have simplified mould structure, and have saved die cost, have improved production efficiency.
Above embodiment has just set forth basic principle of the present utility model and characteristic; the utility model is not limited by above-mentioned example; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various variations and change, and these variations and change all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
