Because there is no hole in the part, or the hole ratio is smaller, the pulling force is bigger during the shaping, easily pulls the edge that has already turned over. Flanging and then forming are not practical for such parts.
In view of the above, the up-down forming and processing apparatus for mesh parts of an airbag according to the present embodiment is substantially the same as that of embodiment 1, except that the up-down forming and processing apparatus for mesh parts of an airbag according to the present embodiment is adapted to form a part blank a first and then form a flange.
Specifically, the flanging female die 9 of the up-and-down forming processing device for the mesh part of the automobile air bag is fixedly arranged at one side end of the lower backing plate 10 facing the upper die holder 1; the forming concave die 16 is movably arranged at one side end of the lower backing plate 10 facing the upper die holder 1; and when the upper die pressing mechanism and the lower die pressing mechanism are in a die splitting state (the die splitting state refers to a state before the upper die pressing mechanism and the lower die pressing mechanism are matched), the end part of the forming female die 16 facing the upper die base 1 is higher than the end part of the flanging female die 9 facing the upper die base 1. It should be noted here that, with respect to the flanging female die 9 being fixedly arranged on the lower cushion plate 10, what is fixedly arranged means only that the flanging female die 9 is assembled with the lower cushion plate 10 in place, and no matter the upper pressing mechanism and the lower pressing mechanism are in a die-splitting state or a die-closing state, the relative position of the flanging female die 9 with respect to the lower cushion plate 10 is unchanged, that is, the flanging female die 9 does not generate relative movement with the lower cushion plate 10. The forming die 16 is movable relative to the lower mat 10, i.e., the position of the forming die 16 relative to the lower mat 10 is variable in a floating manner. Generally, the flanging female die 9 and the forming female die 16 are assembled in a detachable mode relative to the lower cushion plate 10, so that the lower cushion plate can be repaired and replaced conveniently.
For example, in an alternative embodiment, the forming die 16 is connected to a movable rod 11 which penetrates through the lower die holder 15 and the lower bolster 10 in sequence. The movable rod 11 can optionally penetrate through the lower cushion plate 10 and the lower die holder 15 and then be connected with the elastic base in the embodiment 1, so that the structure of the whole device can be simplified on the basis of not influencing the function of the forming female die 16.
The specific implementation principle of the up-and-down forming and processing device for the mesh part of the automobile air bag of the embodiment is as follows:
the forming machine is suitable for forming and flanging the part blank A, and particularly for forming the part blank A, the upper part A2 is formed first, and then the lower part A1 is formed.
The part blank A is placed into a positioning hole of the positioning plate 8, the upper die base moves towards the lower die base, the upper discharging plate 4 presses the positioning plate 8 along with descending of the upper die base, the upper die base continues to press downwards, the forming male die 7 contacts the part blank A, the forming male die 7 presses the part blank A to move downwards together, and when the part blank A enters the forming female die 16 along with the forming male die 7, forming is completed. Then, the forming female die 16 descends along with the part blank A along with the continuous downward movement of the upper die base, when the part blank A contacts the flanging female die 9, the top part 12 descends under the action of the flanging male die 6 and the flanging female die 9, and the flanging is completed. Then, along with the resetting of the upper die base, the part which finishes flanging and forming ejects the flanging female die 9 under the action of the ejector rod 13 and the elastic base. Thus, the processes of flanging and forming the parts at one time are completed.
