Abstract
The utility model relates to a drawing die of a boss shell. The drawing die of the boss shell belongs to the technical field of dies, and comprises an upper die and a lower die which are matched with each other. The stretch die of the boss shell is characterized in that the upper die comprises an upper template, wherein a press convex die is arranged on the bottom portion of the upper template, the lower die comprises a lower template, guide pillars which are used for up and down movement of the upper template are arranged on the left and the right ends of the lower template, a press concave die is arranged on the top portion of the lower template corresponding to the press convex die, an ejector pin is embedded in the middle of the press concave die, and an ejector pin hole is arranged on the press convex die corresponding to the ejector pin. The drawing die of the boss shell is simple in structure, the ejector pin punctures a cold drawing sheet under the interaction of the press convex die and the press concave die and the action of the ejector pin, a round hole is formed on the center of the cold drawing sheet, and the cold drawing sheet stretches along the round hole at the moment, thereby completing processing of the boss shell at last, and effectively preventing the cold drawing sheet from breaking.
Description
Technical field
The utility model relates to a kind of drawing die of boss housing, belongs to technical field of mold.
Background technology
At present, the method that the boss housing usually adopts is: first cold drawn plate being placed between the die mould punch and die mould die that cooperatively interacts, again by power extruding die mould punch and die mould die, thereby is required boss housing with cold drawn sheet metal stretching.This method is adding man-hour, and the boss height of sometimes processing the boss housing is higher, so cold drawn plate breaks easily when extruding, thereby affects the qualification rate of product.
The utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: a kind of drawing die of boss housing is provided, and it is simple in structure, when the higher boss housing of processing boss height, has avoided breaking of cold drawn plate.
The drawing die of boss housing described in the utility model, comprise the upper die and lower die that cooperatively interact, it is characterized in that: patrix comprises cope match-plate pattern, the cope match-plate pattern bottom is provided with the die mould punch, counterdie comprises lower bolster, and two ends, the lower bolster left and right sides are provided with the guide pillar that moves up and down for cope match-plate pattern, and corresponding die mould punch is provided with the die mould die at the lower bolster top, in the embedding of die mould die middle part thimble is arranged, corresponding thimble offers centre hole at the die mould punch.
When practicality, above-mentioned die mould punch and die mould die are decided according to the workpiece shape.During use, cold drawn plate is placed on the die mould die at lower bolster top, then adopt power with cope match-plate pattern along the downward punching press of guide pillar, under the extruding of die mould punch and die mould die, thimble punctures cold drawn plate, is formed centrally therein circular hole, and at this moment cold drawn plate prolongs the circular hole extension, finish at last the processing of boss housing, avoided breaking of cold drawn plate.
In order to make things convenient for the connection of the utility model on punch press, be provided with die shank at the cope match-plate pattern top.
Compared with prior art, the utlity model has following beneficial effect:
Pass through the utility model, it is simple in structure, die mould punch and die mould die cooperatively interact and the effect of thimble under, thimble punctures cold drawn plate, be formed centrally therein circular hole, at this moment cold drawn plate prolongs the circular hole extension, has finished at last the processing of boss housing, has effectively avoided breaking of cold drawn plate.
