[0002] In the process of automobile manufacturing, some parts directly become automobile parts after stamping, and some parts need to go through processes such as welding, machining, or painting after stamping before becoming automobile parts. As one of the key devices, the performance of the stamping part bending device directly affects the production efficiency, quality, and cost of automobile parts.

[0003] For example, in the patent with the authorized publication number CN215467239U in the prior art, the utility model discloses a bending and forming device for automobile hardware stamping parts, including a workbench. A strip-shaped groove is formed through the top and bottom of the workbench. A material pushing mechanism is fixedly installed at the bottom of the workbench. The material pushing mechanism includes a first mounting plate and a second mounting plate. The tops of the first mounting plate and the second mounting plate are vertically fixedly installed at the bottom of the workbench.

A motor is fixedly installed on one side of the first mounting plate, and the output end of the motor is fixedly connected to a threaded shaft.

[0004] However, it is found in the use of this device that it is not convenient to realize the alternate bending processing of two groups of stamping parts, which increases the time occupied by taking and placing the stamping parts and reduces the stamping processing efficiency. Content of the Utility Model

[0005] To solve the above technical problems, the utility model provides a bending device for automobile stamping parts that is convenient for loading and unloading another group of stamping parts while bending one group of stamping parts, thereby improving work efficiency.

The two sets of lower dies are both slidably installed on the guide rail. A driving device is arranged inside the base, and the driving device is used to drive the two sets of lower dies to move towards each other. The supporting plate is installed at the right part of the base through the supporting device, and the supporting device is used to drive the supporting plate to move up and down. The two sets of upper dies are both installed at the bottom end of the supporting plate, and the two sets of upper dies respectively match the positions of the two sets of lower dies; place the stamping part on one of the lower dies, and then drive the two sets of lower dies to move towards each other through the driving device, so that the lower die with the stamping part moves below one of the upper dies. Then drive the supporting plate to move downward through the supporting device, so that the supporting plate drives the two sets of upper dies to move downward, so that one of the upper dies presses and bends the stamping part on the lower die. The other lower die moves to the left part of the base. By placing the stamping part to be processed on the left lower die, when the driving device drives the two sets of lower dies to move towards each other again, the bent stamping part moves to the left part of the base through the lower die, and the stamping part to be bent is conveyed to below the upper die through the other lower die. At this time, collect the bent stamping part and place the stamping part to be bent on the lower die, and so on in a cycle, so as to improve the convenience of feeding and discharging of one set of stamping parts while bending the other set of stamping parts, and improve work efficiency.

After the second bevel gear rotates, drive the two sets of support shafts to rotate towards each other through the meshing with the two sets of first bevel gears. After the two sets of support shafts rotate towards each other, drive the two sets of first telescopic rods to swing towards each other, so that the two sets of first telescopic rods drive the two sets of lower dies to move towards each other, improving the convenience of moving and conveying the stamping part by the two sets of lower dies.

[0008] Preferably, the support device includes a lifting device, multiple groups of guide columns, a connecting plate, multiple groups of second telescopic rods, and multiple groups of springs.

The tops of the multiple groups of second telescopic rods are all connected to the bottom of the connecting plate. The multiple groups of springs are respectively sleeved on the outer side walls of the multiple groups of second telescopic rods. By driving the connecting plate to move downward through the lifting device, the connecting plate drives the support plate to move downward, so that the upper die and the lower die cooperate to bend the stamping part.

The multiple groups of pushing blocks are respectively installed in the multiple through holes of the support plate and the upper die in a vertically sliding manner. The moving ends of the multiple groups of second cylinders are respectively connected to the tops of the multiple groups of pushing blocks. After the upper die bends the stamping part, the second cylinders push the pushing blocks to move downward, so that the pushing blocks push the bent stamping part downward, avoiding the stamping part from sticking to the bottom of the upper die and improving the convenience of the lower die to move and convey the stamping part.

[0011] Preferably, it further includes multiple groups of limiting parts, which are respectively arranged on the outer edges of the two lower dies. By providing the multiple groups of limiting parts, the limiting effect of the stamping part placed on the lower die is improved, and the bending processing accuracy of the stamping part is improved.
