Description
Technical field
The utility model belongs to lithium battery processing technique field, particularly relates to a kind of li battery shell deep-drawing composite mold.
Background technology
At present, cellular li-ion battery aluminium alloy is more and more thinner, for lithium battery aluminium alloy rectangular enclosure, different according to size, can select two kinds of forming technologies: (1) extruding and ironing forming technology; (2) plate repeatedly load-unload and ironing forming technology.High and be typical high box part for dimension precision requirement, although extrusion process is higher than plate repeatedly load-unload production efficiency, save material, but in extrusion process convex mould very easily unstability, cause shell wall thickness uneven, cannot meet design requirement, battery is thinner, then its shell more should not adopt extrusion process.Therefore for the typical li battery shell of intended size, adopt plate repeatedly load-unload and ironing forming technology to be an effective optimal path, but the defects such as the thinning and drawing crack in local in drawing process will be avoided just must to design a kind of deep-drawing composite mold.
Summary of the invention
The utility model provides a kind of li battery shell deep-drawing composite mold, and its structure is simple, easy to use, effectively to solve in drawing process the problems such as the defects such as the thinning and drawing crack in local cause part defective.
In order to achieve the above object, the utility model is by the following technical solutions: a kind of li battery shell deep-drawing composite mold, it is characterized in that upper bolster is connected with backing plate, punch-die fixed head with straight pin successively by filleted corner screw, punch-die fixed head is provided with punch-die, punch-die is connected with binder stripper, be connected with movable matrix below binder stripper, movable matrix is built with loose plug, be connected with punch bottom punch-die, punch is arranged on above punch retainer, and punch retainer is connected with die shoe.Below die shoe, both sides are provided with pull bar, and on pull bar, cover has disk spring, and runs through and be fixed between mounting plate, bottom plate, and upper bolster, die shoe are connected by the accurate guide pillar be fixed in upper bolster, and accurate guide pillar overcoat is provided with accurate guide pin bushing.
Particularly, described mounting plate both sides are connected with movable matrix with push rod respectively by straight pin, be provided with polyurethane rubber, be connected by push rod with loose plug in the middle of mounting plate.
Particularly, described upper bolster is provided with soket head cap screw and is connected with binder stripper, outer casing spring on soket head cap screw.
The beneficial effects of the utility model are: (1) the utility model utilizes cluster spring to provide the Variable BHF of Li Battery Aluminum Shell drawing and forming, the downstream rate of loose plug and the downstream rate of movable matrix is not only made to form speed difference, and ensure that punch-die is evenly descending, guarantee that blanking is smooth, realize Variable BHF drawing, especially effectively can prevent the thinning and Pull crack defect in local in drawing process.(2) for the typical li battery shell of intended size, adopt plate repeatedly load-unload and ironing forming technology, achieve the batch production of li battery shell.(3) the utility model compact conformation, simple, the li battery shell dimensionally stable of production, qualification rate reaches 98%, achieves good techno-economic effect.
Accompanying drawing explanation

1. mounting plates, 2. disk spring, 3. pull bar in figure, 4. polyurethane rubber, 5. push rod, 6. die shoe, 7. punch retainer, 8,14. straight pins, 9. guide pin, 10. accurate guide pillar, 11. accurate guide pin bushings, 12. upper bolsters, 13,18. soket head cap screws, 15. punch-die fixed heads, 16. backing plates, 17. punch-dies, 19. springs, 20. binder strippers, 21. loose plugs, 22. movable matrixes, 23. punch, 24. push rods.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further explained.
As shown in Figure 1, a kind of li battery shell deep-drawing composite mold, it is characterized in that: upper bolster 12 is connected with backing plate 16, punch-die fixed head 15 with straight pin 14 successively by filleted corner screw 13, punch-die fixed head 15 is provided with punch-die 17, punch-die 17 is connected with binder stripper 20, binder stripper 20 is connected with movable matrix 22 below, movable matrix 22 is built with loose plug 21, be connected with punch 23 bottom punch-die 17, punch 23 is arranged on above punch retainer 7, and punch retainer 7 is connected with die shoe 6.Die shoe 6 below both sides is provided with pull bar 3, and on pull bar 3, cover has disk spring 2, and runs through and be fixed between mounting plate 1, bottom plate.Upper bolster 12, die shoe 6 are connected by the accurate guide pillar 10 be fixed in upper bolster 12, and accurate guide pillar 10 overcoat is provided with accurate guide pin bushing 11.
Particularly, described mounting plate 1 both sides are connected with movable matrix 22 with push rod 24 respectively by straight pin 8, be provided with polyurethane rubber 4, be connected by push rod 5 with loose plug 21 in the middle of mounting plate 1.
Particularly, described upper bolster is provided with soket head cap screw 18 and is connected with binder stripper 20, outer casing spring 19 on soket head cap screw 18.
During work, blank is with guide pin 9 and stock guide location, patrix drive punch-die 17 and holding pad 20 descending, binder stripper 20 first contacts with the blank on movable matrix 22, flanging is realized under the forceful action of disk spring 2, subsequently, punch-die 17 profile and movable matrix 22 interact, complete blanking, along with punch-die 17 continues descending, loose plug 21 and punch-die 17 realize flanging, punch 23 relative uplink, Li Battery Aluminum Shell drawing is started under flanging situation, when top mold frame walks to lower fulcrum, drawing is complete, then patrix fast uplink, now loose plug 21 is thereupon up, namely the Li Battery Aluminum Shell be attached on punch 23 is ejected, waste material unloads by binder stripper 20 subsequently.
Below disclose the utility model with preferred embodiment, so itself and be not used to limit the utility model, all employings are equal to replacement or the technical scheme that obtains of equivalent transformation mode, all drop within protection domain of the present utility model.
