[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] When bending, existing bending devices are not easy to accurately control the bending degree and bending position of parts, and bending errors are prone to occur. Especially when batch producing parts, the bending degrees of multiple parts may be inconsistent, such as the bending degree is too large or too small, or the bending position is offset, affecting the quality of the parts.

[0022] To solve the defects of the above bending device during use, please refer to Figure 1-Figure 5The utility model provides a bending prefabrication processing device for automobile sheet parts, which can determine the bending angle and bending position of the parts, reduce bending errors, and improve the accuracy of the equipment in bending parts. The bending prefabrication processing device is based on a processing table 1. A bending mechanism 2 is provided at one end of the top of the processing table 1. The bending mechanism 2 is arranged to be fixedly mounted on a hydraulic cylinder 21 on the top of the processing table 1. The output end of the hydraulic cylinder 21 is fixedly connected to a bending head 22. Driving the hydraulic cylinder 21 can drive the bending head 22 to move. A main positioning plate 3 is slidably installed on the other end of the top of the processing table 1, and a main shifting member 8 for driving the main positioning plate 3 to slide is provided at the end of the processing table 1. Two bending rollers 6 are symmetrically slidably installed on the processing table 1. The bending rollers 6 are arranged between the bending mechanism 2 and the main positioning plate 3. The two bending rollers 6 are used to support the parts. The bending head 22 pushes the parts to bend the parts. The main positioning plate 3 is used to determine the bending angle of the parts. When bending, the bending head 22 pushes the parts each time to ensure the accuracy and consistency of the bending angle and avoid the situation where the bending angle is too large or too small. , and the bottom of the processing table 1 is provided with an adjusting mechanism 7 that drives the two bending rollers 6 to slide in opposite directions. The spacing between the two bending rollers 6 can be adjusted through the adjusting mechanism 7, thereby expanding the adjustable range of the bending degree of the part. A secondary positioning plate 4 is slidably installed on one side of the top of the processing table 1, and a secondary shifting member 5 is provided on the side of the processing table 1 for driving the secondary positioning plate 4 to slide. The secondary positioning plate 4 is used to position the part, thereby determining the bending position of the part. When bending, one end of the part is placed against the secondary positioning plate 4 so that the bending position of the part is aligned with the center line of the two bending rollers 6. Subsequent parts can be bent directly against the secondary positioning plate 4, which can enhance the accuracy of the part position bending. The position of the part bending can also be adjusted by adjusting the position of the secondary positioning plate 4. The bending degree and bending position of the part are determined by the main positioning plate 3 and the secondary positioning plate 4, thereby improving the accuracy of the equipment in bending parts.

[0023] By controlling the distance between the main positioning plate 3 and the bending roller 6, the bending degree of the part can be controlled. In order to conveniently control the distance between the main positioning plate 3 and the bending roller 6, a support 81 fixedly mounted on the end of the processing table 1 is provided. A support plate 82 is rotatably mounted on the support 81, and a fastening bolt 84 is installed on the side of the support 81.

The upper end of the support plate 82 is rotatably mounted in the connecting seat 83. When adjusting the position of the main positioning plate 3, rotating the support plate 82 to cooperate with the connecting seat 83 can drive the main positioning plate 3 to slide, slide the main positioning plate 3 to the specified position, tighten the fastening bolt 84 to fix the support plate 82, and the support plate 82 can support the main positioning plate 3, thereby driving the bending mechanism 2 to bend the part until it is against the main positioning plate 3.

[0024] By controlling the distance between the auxiliary positioning plate 4 and the bending roller 6, the bending position of the part can be adjusted. A screw rod 51 is provided which is threadedly connected to the bottom of the auxiliary positioning plate 4. A strip groove 52 is provided on the processing table 1 for the screw rod 51 to rotate. The bottom of the auxiliary positioning plate 4 is slidably installed in the strip groove 52, and one end of the screw rod 51 passes through the processing table 1 and is fixedly connected to a knob. Turning the knob drives the screw rod 51 to rotate, and the rotation of the screw rod 51 can drive the auxiliary positioning plate 4 to slide, so that the position of the auxiliary positioning plate 4 can be adjusted. When bending, the end of the part can be placed against the auxiliary positioning plate 4.

[0025] The two levers 73 are connected to each other by means of a lever 74, and the lever 74 is connected to the bottom of the lever 74 so that the lever 74 can move relative to the top of the lever 74.

[0026] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. In addition, the present invention is mainly used to protect mechanical devices, so the control method and circuit connection are no longer explained in detail in the present invention.
