[0002] As a needle-shaped tool, the plug pin is used in various fields of production and life. During the production process of the plug pin, it is often necessary to bend it so that it can meet different usage requirements.

[0003] When bending the pins on the workpiece, some pins need to be bent to form C-shaped pins. During the bending process, the pins need to be bent multiple times because the C-shaped pins have multiple bending points. As a result, most existing equipment bends once and then puts them into another set bending equipment for bending again, which reduces the processing efficiency.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a secondary bending pin insertion machine, which performs a first bend on the pin by setting a fixed frame and a first bending plate that rotate simultaneously. When the first bending plate is close to the supporting surface of the pressure plate, the cooperation of the limit plate and the supporting surface prompts the second bending plate to rotate to bend the pin for the second time, thereby producing a C-shaped pin after the secondary bending.

[0006] The above-mentioned technical purpose of the utility model is achieved through the following technical scheme: a secondary bending pin insertion machine, comprising a frame, a support plate horizontally arranged on the frame, a vertically sliding pressure plate arranged on the frame, the pressure plate and the support plate are arranged correspondingly, a fixing frame for fixing a workpiece is arranged on one side of the support plate, a first vertically rotating bending plate is arranged on the side of the support plate away from the fixing frame, a second vertically rotating bending plate is arranged on the end of the first bending plate away from the support plate, and mutually connected placement grooves are provided on the end faces of the support plate, the rotation axis of the first bending plate is collinear with the right-angled side of the end side of the support plate, and the rotation axis of the second bending plate is collinear with the right-angled side of the end side of the first bending plate away from the support plate.

[0007] The utility model is further configured as follows: the fixing frame is rotatably arranged on the frame body, and the rotation axis of the fixing frame is colinear with the right-angled edge of the end side of the support plate away from the first bending plate.

When the end of the first bending plate away from its rotating shaft is close to the pressure plate, the limit plate on the second bending plate is in contact with the supporting surface of the pressure plate in advance, and the supporting surface is in contact with the inclined extrusion surface. The first bending plate continues to be rotated so that under the action of the supporting surface and the extrusion surface, the limit plate is prompted to rotate and then drive the second bending plate to rotate.

The end surfaces of the support plate 2, the first bending plate 5 and the second bending plate 6 are provided with mutually connected placement grooves 7, the rotation axis of the first bending plate 5 is collinear with the right-angled side of the end side of the support plate 2, the rotation axis of the second bending plate 6 is collinear with the right-angled side of the end side of the first bending plate 5 away from the support plate 2, the rotation axis of the fixed frame 4 is collinear with the right-angled side of the end side of the support plate 2 away from the first bending plate 5, and the pressing surface of the pressure plate 3 has the same width as the top surface of the support plate 2.

[0022] In the above embodiment, it should be noted that the fixing frame 4 is used to fix the workpiece. When the workpiece needs to be bent, the staff fixes the workpiece on the fixing frame 4, the pin hole of the workpiece corresponds to the placement groove 7, and then places the pin in the placement groove 7. The staff pushes the pin into the pin hole and then rotates the fixing frame 4 and the first bending plate 5 at the same time to perform a first bend on the pin. After the first bending plate 5 is bent, the second bending plate 6 is rotated to bend the pin for a second time, thereby producing a C-shaped bent pin.

[0023] refer to Figure 4As shown: a first transmission gear 8 coaxial with the fixed frame 4 is welded at one end, a second transmission gear 9 is welded at the end of the first bending plate 5 away from the first transmission gear 8, the rotation axis of the second transmission gear 9 is colinear with the rotation axis of the first bending plate 5, and two horizontally sliding racks 10 are arranged on the frame body 1, and the two racks 10 are respectively meshed with the first transmission gear 8 and the second transmission gear 9, and a driving member is arranged on the frame body 1 to drive the two racks 10 to slide simultaneously.

[0024] In the above embodiment, it should be noted that the purpose of the driving member is to push the rack 10 to slide, so the driving member can be a linear driving device without further elaboration. After the pin insertion is completed, the two racks 10 are pushed to slide by the driving member, and then the two racks 10 drive the first transmission gear 8 and the second transmission gear 9 to rotate, prompting the fixing member and the first bending plate 5 to rotate, thereby achieving the first bending effect.

[0025] refer to Figure 4 As shown: both ends of the second bending plate 6 are integrally formed with a limit plate 11 perpendicular thereto, the top of the limit plate 11 is higher than the horizontal plane where the second bending plate 6 is located, the end of the limit plate 11 close to the second bending plate 6 is provided with an inclined extrusion surface 12, one end of the extrusion surface 12 is provided with a limit surface 13 perpendicular to the second bending plate 6, and the pressure plate 3 is provided with a support surface 14 corresponding to the limit surface 13.

[0026] In the above embodiment, the driving member pushes the rack 10 to slide, prompting the fixing frame 4 and the first bending plate 5 to rotate to bend the pin.

The first bending plate 5 continues to rotate so that under the action of the supporting surface 14 and the extrusion surface 12, the limit plate 11 is prompted to rotate and then drive the second bending plate 6 to rotate. When the first bending plate 5 is completely fitted with the pressure plate 3, the limit surface 13 on the limit plate 11 is completely fitted with the support surface 14, thereby achieving a secondary bending of the pin.

[0027] Further: an elastic member is fixedly provided on the first bending plate 5 , and an end of the elastic member away from the first bending plate 5 is fixedly connected to the second bending plate 6 , and the elastic member has elastic potential energy for driving the second bending plate 6 away from the first bending plate 5 .

[0028] In the above embodiment, it should be noted that the elastic member can be set as a spring, a coil spring, etc. The elastic member can drive the second bending plate 6 away from the first bending plate 5. The setting of the elastic member can make the driving member push the rack 10 to slide after the pin is bent to reset the fixed frame 4 and the first bending plate 5. At the same time, the elastic member can push the limit plate 11 to drive the second bending plate 6 to reset without affecting the subsequent bending work.

[0029] Working principle:

[0030] The staff fixes the workpiece on the fixing frame 4, and the pin hole of the workpiece corresponds to the placement slot 7. Then the pin is placed in the placement slot 7. The staff pushes the pin into the pin hole, and the driving member pushes the two racks 10 to slide, so that the two racks 10 drive the first transmission gear 8 and the second transmission gear 9 to rotate, prompting the fixing member and the first bending plate 5 to rotate to achieve the first bending. When the end of the first bending plate 5 away from its rotating shaft is close to the pressure plate 3, the limit plate 11 on the second bending plate 6 is in contact with the supporting surface 14 of the pressure plate 3 in advance, and the supporting surface 14 is in contact with the inclined extrusion surface 12. Continue to rotate the first bending plate 5 so that under the action of the supporting surface 14 and the extrusion surface 12, the limit plate 11 is prompted to rotate and then drive the second bending plate 6 to rotate. When the first bending plate 5 is completely fitted with the pressure plate 3, the limit surface 13 on the limit plate 11 is completely fitted with the support surface 14, thereby achieving a secondary bending of the pin, and then producing a C-shaped bent pin.
