Abstract
The utility model relates to the technical field of machinery, and particularly relates to a one-step forming die for a lithium battery aluminum cover plate. The one-step forming die comprises an upper die base, rotating shafts, a forming male die, a stripper plate, a female die plate, a lower die base, a male die guide block, a lower die inclined wedge and an inclined wedge guide block, wherein each rotating shaft is arranged on each of the left side and the right side on the top of the forming male die; the inclined wedge guide block is fixed in the center of the top of the lower die base; the lower die inclined wedge is sleeved on the outer side of the inclined wedge guide block; the male die guide block is fixed on the top of the lower die base; and the female die plate is sleeved on the outer side of the male die guide block. Compared with the prior art, the one-step forming die has the advantages that due to a structural design of a swinging forming male die during punching, a clearance and a forming angle of the lithium battery aluminum cover plate during forming are changed gradually from large to small, so that a negative angle edge of which the angle is less than 90 degrees of the lithium battery aluminum cover plate is formed by a step; and therefore, scratches on the surface of the lithium battery aluminum cover plate are reduced, the yield of the die is increased, and the punching cost is reduced.
Description
Technical field
The utility model relates to field of mechanical technique, specifically a kind of one-time-shaped mould of lithium battery Aluminum cover.
Background technology
Along with developing of automobile industry, increasing to the demand of lithium battery Aluminum cover, and existing mould can't be realized Hyundai Motor desired high production capacity of industry and low cost of stamping.Particularly for four limits the lithium battery Aluminum cover less than 90 degree negative angle moulding is arranged, existing diel needs the moulding of 2-3 operation ability.For the production capacity that improves mould and reduce cost of stamping, must reduce the mould operation.Therefore, design a kind of can one-shot forming be vital less than the mould on 90 degree negative angle limits.
Summary of the invention
The purpose of the utility model is the deficiency that overcomes prior art, provide a kind of can one-time formed lithium battery Aluminum cover less than the mould on 90 degree negative angle limits.
In order to achieve the above object; The utility model comprises patrix base, rotating shaft, forming convax mould, stripper, concave template, counterdie base, punch guide pad, counterdie wedge and wedge guide pad; It is characterized in that: the top of forming convax mould is embedded on the fixed head of patrix base bottom; The and arranged on left and right sides at forming convax mould top respectively is provided with a rotating shaft, and the bottom of forming convax mould embeds in the stripper; Counterdie base top central authorities are fixed with the wedge guide pad, and the counterdie wedge is set in the wedge guide pad outside, and the punch guide pad is fixed on the counterdie base top and is positioned at the outside of counterdie wedge, and concave template is set in the outside of punch guide pad.
The utility model is compared with prior art; Adopt the structural design of the forming convax mould of swinging in the punching course; Realize the forming process intermediate gap and the descending gradual change of moulding angle of lithium battery Aluminum cover; Thereby realize that the lithium battery Aluminum cover less than 90 degree negative angle limit one-shot formings, has not only reduced the scratch on lithium battery Aluminum cover surface, also improved mould production capacity, reduced cost of stamping.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the work sketch map of the utility model.
Referring to Fig. 1,1 is the patrix base; 2 is rotating shaft; 3 is forming convax mould; 4 is stripper; 5 is concave template; 6 is the counterdie base; 7 is the punch guide pad; 8 is the counterdie wedge; 9 is the wedge guide pad.
The specific embodiment
Combine accompanying drawing that the utility model is done further describes at present.
Referring to Fig. 1, the utility model comprises patrix base, rotating shaft, forming convax mould, stripper, concave template, counterdie base, punch guide pad, counterdie wedge and wedge guide pad.The top of forming convax mould 3 is embedded on the fixed head of patrix base 1 bottom, and the and arranged on left and right sides at forming convax mould 3 tops respectively is provided with a rotating shaft 2, and the bottom of forming convax mould 3 embeds in the stripper 4; Counterdie base 6 center of top are fixed with wedge guide pad 9, and counterdie wedge 8 is set in wedge guide pad 9 outsides, and punch guide pad 7 is fixed on counterdie base 6 tops and is positioned at the outside of counterdie wedge 8, and concave template 5 is set in the outside of punch guide pad 7.
The utility model is when work; Punch press is descending, and stripper 4 contact counterdie wedges 8 and the top plan that makes top plan that counterdie wedge 8 comes downwards to counterdie wedge 8 and concave template 5 are on same plane, and then forming convax mould 3 begins descending; When moulding punch 3 touches punch guide pad 7; Driven in rotation axle 2 rotates, and in the forming convax mould 3 descending forming processes, the gap is descending to gradually change like this; At utmost reduce the galled spots of lithium battery Aluminum cover, that has also realized the lithium battery Aluminum cover spends negative angle limit one-shot formings less than 90.Punch press is up, and whole process and just in time opposite when descending realizes that demoulding punch press and patrix get back to original state, treats next stroke, the end-of-job of the utility model.
