[0002] In the modern automotive manufacturing industry, as process development levels continue to improve, cost reduction becomes a crucial consideration. Reducing process development and manufacturing costs, particularly minimizing the initial investment in process development while ensuring output, has gradually become an important research topic.
[0003] Existing stamped parts often have certain problems when bending. The bending process of stamped parts is often not uniform and stable, the bending effect is relatively poor, and it is easy to cause the stamped parts to shift in position, which affects the dimensional deviation of the stamped parts, resulting in substandard quality. This reduces the bending operation of stamped parts and is inconvenient to use. In order to address the above problems, a pre-clamping bending fixture for stamped parts is proposed for improvement and upgrading. Utility Model Content

Two bending cylinders are rotatably installed inside the upper part of the bending machine base, and a stamped sheet metal part is provided on the upper surface of the bending machine base. Limiting components are provided on both sides of the stamped sheet metal part. A bending module is provided above the stamped sheet metal part and is located inside a mounting plate. Limiting plates are symmetrically provided on the front and rear sides of the outer wall of the mounting plate, and one end of the limiting plate is engaged with the outer wall of the bending module.
[0007] Furthermore, the moving component includes a dual-axis motor, connecting rods, and a first bevel gear. The dual-axis motor is fixedly installed inside the bending machine base, and threaded rods are fixedly connected to both ends of the dual-axis motor.

[0008] Furthermore, both first bevel gears are meshed with second bevel gears, and both second bevel gears have threaded rods fixedly connected to their upper ends. Both threaded rods are rotatably installed inside the bending machine, and both the first bevel gears and the second bevel gears are rotatably installed inside the bending machine.
[0009] Furthermore, the outer walls of the two connecting rods are rotatably disposed inside the limiting sleeve, and the lower end of the limiting sleeve is fixedly connected to the inside of the bending machine.

[0010] Furthermore, two sets of positioning shafts are symmetrically arranged on the front and rear sides of the outer wall of the bending machine platform, and a return spring is connected to the outer wall of the positioning shaft.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This utility model device includes a dual-axis motor, connecting rods, a first bevel gear, a threaded rod, a bending module, a bending cylinder, a return spring, and a positioning pin. The dual-axis motor drives two connecting rods to rotate, which in turn drives the first bevel gear to rotate.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0023] like Figure 1 - Figure 4 As shown in the figure, this embodiment provides a pre-clamping bending fixture for stamped parts, including a bending machine 1. The bending machine 1 is equipped with a moving component 2. Two bending cylinders 7 are rotatably installed inside the upper end of the bending machine 1. A stamped sheet metal part 5 is provided on the upper surface of the bending machine 1. Limiting components 6 are provided on both sides of the stamped sheet metal part 5. A bending module 3 is provided above the stamped sheet metal part 5 and is located inside the mounting plate 9. Limiting plates 4 are symmetrically provided on the front and rear sides of the outer wall of the mounting plate 9, and one end of the limiting plate 4 is snapped onto the outer wall of the bending module 3.
[0024] Preferably, the moving component 2 includes a dual-axis motor 21, connecting rods 22, and first bevel gears 24. The dual-axis motor 21 is fixedly installed inside the bending machine base 1, and threaded rods 26 are fixedly connected to both ends of the dual-axis motor 21. One end of each of the two threaded rods 26 is fixedly connected to a first bevel gear 24. Both first bevel gears 24 are meshed with second bevel gears 25. The upper ends of both second bevel gears 25 are fixedly connected to threaded rods 26. Both threaded rods 26 are rotatably installed inside the bending machine base 1. Both first bevel gears 24 and second bevel gears 25 are rotatably installed inside the bending machine base 1. The outer walls of the two connecting rods 22 are rotatably disposed inside the limiting sleeve 23, and the lower end of the limiting sleeve 23 is fixedly connected to the inside of the bending machine base 1. The outer walls of the two threaded rods 26 are threadedly connected to both ends of the mounting plate 9.
[0025] The dual-axis motor 21 drives the two connecting rods 22 to rotate, and then the two connecting rods 22 drive the first bevel gear 24 to rotate, so that the first bevel gear 24 drives the threaded rod 26 on the second bevel gear 25 to rotate stably. Thus, the two threaded rods 26 drive the bending module 3 on the mounting plate 9 to descend stably and perform a bending operation on the pre-clamped stamping part. When the stamping part is bent onto the two bending cylinders 7, the two bending cylinders 7 rotate, and at the same time drive the positioning pin 81 to rotate, which stretches the return spring 8 on the positioning shaft 82 and then resets it, making it convenient to perform the bending operation on the stamping part.
[0026] Preferably, two sets of positioning shafts 82 are symmetrically arranged on the front and rear sides of the outer wall of the bending machine base 1, and a return spring 8 is connected to the outer wall of the positioning shaft 82. The other end of the return spring 8 is connected to the positioning pin 81, and the positioning pin 81 is fixedly installed on the bending cylinder 7. A hinge plate 83 is arranged below the two sets of positioning shafts 82, and one end of the hinge plate 83 is located on one side of the bending cylinder 7. The limiting component 6 includes a mounting base 61, a cylinder 62, and a clamping plate 63. There are two mounting bases 61, and a cylinder 62 is fixedly arranged inside the mounting base 61. One end of each cylinder 62 is fixedly connected to the clamping plate 63. Two guide telescopic rods 64 are symmetrically arranged on the inner wall of the clamping plate 63, and one end of the guide telescopic rod 64 is connected to the inside of the mounting base 61.
[0027] By driving the cylinders 62 inside the two mounting bases 61 to work, the two cylinders 62 drive the clamping plate 63 to move relative to each other to limit the stamping part. At the same time, the guide telescopic rod 64 is used to limit the relative movement of the clamping plate 63.
[0028] The working principle and process of this utility model are as follows: First, the operator places the stamped sheet metal part on the bending machine 1. At this time, the cylinders 62 inside the two mounting seats 61 are driven to move the clamping plates 63 relative to each other to limit the stamped part. At the same time, the guide telescopic rods 64 limit the relative movement of the clamping plates 63. After the stamped part is pre-clamped and limited, the external power supply is turned on, and the dual-axis motor 21 inside the bending machine 1 drives the two connecting rods 22 to rotate. Then, the two connecting rods 22 drive the first bevel gear 24 to rotate. The first bevel gear 24 drives the threaded rod 26 on the second bevel gear 25 to rotate stably. As a result, the two threaded rods 26 drive the bending module 3 on the mounting plate 9 to descend stably and perform a bending operation on the pre-clamped stamping part. When the stamping part is bent onto the two bending cylinders 7, the two bending cylinders 7 rotate, which at the same time drives the positioning pin 81 to rotate and stretch the return spring 8 on the positioning shaft 82. After the stamping part is bent, the bending cylinder 7 returns to its original position. The hinge plate 83 is set to limit the rotation of the bending cylinder 7, which is beneficial to the relative stability when bending the pre-clamped stamping part.
