[0003] At present, with the development of science and technology, traditional straight ping pins no longer meet design requirements. Ping pins need to be bent into different angles to meet assembly needs. However, ping pins are very thin and small, and bending them is very time-consuming and laborious. In addition, it is not easy to control the angle of bending, and production efficiency is slow. Summary of the Invention

[0005] An automatic bending device for square needles, comprising a frame body, a pressing portion mounted on the frame body, and a bending portion for bending, wherein a breaking portion is further mounted on the frame body;

[0006] The pressing part includes a pressing bracket fixedly connected to the frame body, and a first driving element and a first guide block mounted on the pressing bracket. The output end of the first driving element is fixedly connected to the first pressing block, and the first pressing block slides in the first guide block. A fixed block, a supporting block, and a second pressing block are also mounted on the frame body. The second pressing block is used to press the parts.

[0007] The bending portion includes at least two groups of first slide rails fixedly connected to the frame body, a first sliding seat sliding on the first slide rails, and a second driving element driving the first sliding seat to slide, the first sliding seat is fixedly connected to at least two groups of second slide rails, the second slide rails are slidably connected to the second sliding seat, the second sliding seat is connected to the third driving member, and the second sliding seat is fixedly connected to the bending block.

[0008] Furthermore, it also includes a breaking portion and a feeding portion for interrupting the parts;

[0009] The feeding part includes a feeding bracket and a material belt arranged on the feeding bracket, the material belt is wound on the feeding bracket through a material roll, and a plurality of square pins are arranged on the material belt;

[0010] The breaking part includes a breaking bracket fixed on the frame body and a fourth driving element and a blade block fixed on the breaking bracket. The output end of the fourth driving element is connected to the breaking block. When the material strip passes through the blade block, the fourth driving element drives the breaking block to press down and cut the material strip.

[0011] Furthermore, the pressing block is provided with a plurality of first pressing teeth at one end away from the first driving element, and the first pressing teeth are used to peel the square needle from the material strip.

[0012] Furthermore, the fixing block is fixedly connected to the supporting block, and the fixing block is further provided with a second pressing tooth cooperating with the first pressing tooth. When the first pressing tooth presses down to peel off the pin, the pin can be fixed together with the second pressing tooth.

[0013] Furthermore, the support block is provided with a groove for accommodating the material strip, and the material strip slides in the groove.

[0014] Furthermore, the crushing bracket is also fixedly connected to a second guide block for guiding the crushing block.

[0015] Beneficial effects of the utility model:

[0016] The feeding part of the utility model feeds the material strip into the pressing part along the groove of the supporting block. The pressing block of the pressing part peels the pin from the material strip and presses it tightly with the fixed block. Then the bending part drives the bending block to bend the pin. The material strip moves forward and is broken and recycled through the breaking part. The ping pin can be bent quickly, the production efficiency is accelerated, the bending is performed by automated machinery, and the yield rate is improved. BRIEF DESCRIPTION OF THE DRAWINGS
