Detailed Description

In order to make the objects, contents and advantages of the present invention clearer, the following description will be made in further detail with respect to the embodiments of the present invention.

The utility model provides a pair of general bending and flanging die, characterized by: the device comprises an upper template 1, a convex die holder 2, a combined convex die 3, a screw 4, a screw 5, a screw 6, a combined external flanging concave die 7, a hole flanging convex die 8, a forming concave die 9, a screw 10, a transition rod 11, an air cushion rod 12, a transition plate 13, a concave die holder 14, a lower template 15, a forming convex die 16 and a forming convex die 17;

the lower end of the male die holder 2 is fixedly connected with the lower end of the upper die plate 1 through a screw 5, the combined male die 3 is fixed at the lower end of the male die holder 2 through a screw 4, the combined external flanging female die 7 is fixed at the upper part of the female die holder 14 through a screw 6, the hole flanging male die 8 is pressed on the female die holder 14, the female die holder 14 is fixed on the lower die plate 15 through a screw 10, the internal shape of the forming female die 9 is matched with the hole flanging male die 8, and the external shape of the forming female die 9 is matched with the;

the transition rod 11, the transition plate 13 and the air cushion rod 12 are sequentially arranged in the lower template 15, and the transition rod 11 is contacted with the bottom of the forming female die 9 and can jack the forming female die;

the forming male die 16 and the forming male die 17 are used for forming special-shaped packages at different positions of a part, are respectively pressed on the die holder 14 and are matched with the forming female die 9;

the utility model discloses utilize punching press lathe air cushion pressure adjustable function, provide the condition for merging the punching press process. The utility model provides a general bending, take shape, compound mould of three processes of turn-ups reduces to one set of mould by three sets of moulds, has reduced mould quantity, has reduced manufacturing cost, has improved production efficiency.

The working process is as follows:

1. placing a part blank on a forming female die 9, positioning by using a hole flanging male die 8, and bending (2-R104, R96) the part by combining the male die 3 and the forming female die 9 to form when a punch slide block descends;

2. the slide block continues to move downwards, the combined male die 3 is matched with the forming female die 9, the combined appearance flanging female die 7 and the hole flanging male die 8, and appearance flanging and long round hole flanging steps of the part are completed;

3. the slide block continues to move downwards, and the combined male die 3 is matched with the forming male die 16 and the forming male die 17 to complete the forming of the part special-shaped bag.
