Abstract

An improved reverse drawing die is characterized in that an upper die plate is connected with a concave die, the upper end of a top rod slidably matching with a lower die plate is provided with a blank holder matching with the concave die, the lower die plate is connected with a convex die matching with the concave die, and the convex die is formed by connecting a die head and a die body. The reverse drawing die can match with die heads with various shapes, and when the shape of the front end of a drawn workpiece is required to be changed, a user only needs to replace a die head with corresponding shape. In addition, when the die head is worn and can not be used, the user only needs to change the die head. The improved reverse drawing die is reasonable in structure, can greatly reduce matching cost and using cost of the concave die, and leads the concave die to be adjusted conveniently and easily.

Description

Improved negative drawing mould
Technical field
The utility model relates to the sheet metal tubular mould that stretches, specifically a kind of negative drawing mould.
Background technology
The basic structure of existing a kind of negative drawing mould is: link between cope match-plate pattern and the die, the blank holder of taking a seat and match with die in the push rod upper end that is slidingly matched with lower bolster, be connected with the punch that cooperates with die on the lower bolster, punch is holistic column.Because after sheet metal is stretched and is tubular, the shape of its front end is determined by the shape of nose of punch, therefore punch is that the deficiency of a global existence is: 1, single punch can only process the single workpiece of front end shape, for the variform requirement of different workpieces front end, need to be equipped with a plurality of punch, the cost of mould is big; 2, wear up to can not use the time when the head of punch, whole punch all needs to scrap replacing, the use cost height of punch.
The utility model content
The purpose of this utility model is to provide a kind of improved negative drawing mould, and the cost of manufacture and the use cost of this drawing die are low.
For achieving the above object, the utility model adopts following scheme: improved negative drawing mould, link between cope match-plate pattern and the die, the blank holder of taking a seat and match with die in the push rod upper end that is slidingly matched with lower bolster, be connected with the punch that cooperates with die on the lower bolster, punch is made of die head and the connection of mould body two parts.
By such scheme as seen, the negative drawing mould that the utility model provides can be equipped with the die head of multiple shape, when the workpiece front end shape need that is stretched changes, only need to change the die head of respective shapes, in addition, when die head wears up to can not use the time, only need to change die head.
The utility model is rational in infrastructure, and it can reduce the supporting cost and the use cost of punch greatly, and punch adjustment replacing is convenient, easy.
Description of drawings
Accompanying drawing is the structural representation of the utility model one embodiment.
The specific embodiment
Further specify the utility model below in conjunction with embodiment and accompanying drawing.
Referring to accompanying drawing
Link between cope match-plate pattern 1 and the die 2, the blank holder 3 with taking a seat and match with die 2 in push rod 6 upper ends that lower bolster 7 is slidingly matched is connected with the punch that cooperates with die 2 on the lower bolster 7, and punch is made of die head 4 and the connection of mould body 5 two parts.The mode that die head 4 and mould body 5 connect is: the bottom of die head 4 has boss 4a, and boss 4a has external screw thread, and the front end of mould body 5 has screwed hole 5a, passes through thread connection between boss 4a and screwed hole 5a.

Claims (2)

1. improved negative drawing mould, link between cope match-plate pattern and the die, blank holder with taking a seat and match with die in the push rod upper end that lower bolster is slidingly matched is connected with the punch that cooperates with die on the lower bolster, it is characterized in that: punch is made of die head and the connection of mould body two parts.
2. according to the described improved negative drawing mould of claim 1, it is characterized in that: the bottom of die head has boss, and boss has external screw thread, and the front end of mould body has screwed hole, passes through thread connection between boss and screwed hole.
