Description
Technical field
The invention belongs to lithium battery processing technique field, relate in particular 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) repeatedly pull and stretch and ironing forming technology of plate.High and be typical high box part for dimension precision requirement, although extrusion process is than plate, repeatedly deep-drawing technique production efficiency is high, save material, but in extrusion process convex mould unstability very easily, cause shell wall thickness inhomogeneous, cannot meet design requirement, battery is thinner, and its shell more should not adopt extrusion process.Therefore for the typical li battery shell of intended size, adopt plate repeatedly pull and stretch and ironing forming technology be an effective optimal path, but to avoid the defect such as local attenuation and drawing crack in drawing process just must a kind of deep-drawing composite mold of design.
Summary of the invention
The invention provides a kind of li battery shell deep-drawing composite mold, it is simple in structure, easy to use, has effectively solved in drawing process the defect such as local attenuation and drawing crack and has caused the problems such as part is defective.
In order to achieve the above object, the technical solution adopted in the present invention is: a kind of li battery shell deep-drawing composite mold, it is characterized in that upper bolster passes through filleted corner screw and is connected successively with backing plate, punch-die fixed head with straight pin, punch-die fixed head is provided with punch-die, punch-die is connected with binder stripper, below binder stripper, be connected with movable matrix, loose plug is housed in movable matrix, punch-die bottom is connected with punch, 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 connect by the accurate guide pillar being fixed in upper bolster, and accurate guide pillar overcoat is provided with accurate guide pin bushing.
Concrete, described mounting plate both sides are connected with movable matrix with push rod by straight pin respectively, in the middle of mounting plate, are provided with polyurethane rubber, by push rod, are connected with loose plug.
Concrete, on described upper bolster, be provided with soket head cap screw and be connected with binder stripper, outer casing spring on soket head cap screw.
The invention has the beneficial effects as follows: (1) the present invention utilizes cluster spring that the Variable BHF of Li Battery Aluminum Shell drawing and forming is provided, not only make the downstream rate of loose plug and the downstream rate of movable matrix form speed difference, and guarantee that punch-die is evenly descending, guarantee that blanking is smooth, realize Variable BHF pull and stretch, especially in drawing process, can effectively prevent local attenuation and Pull crack defect.(2) for the typical li battery shell of intended size, adopt plate repeatedly pull and stretch and ironing forming technology, realized the batch production of li battery shell.(3) compact conformation of the present invention, simple, the li battery shell dimensionally stable of production, qualification rate reaches 98%, has obtained good techno-economic effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
