Description

Technical Field

[0002] During the bending process of metal sheets, due to the elastic deformation of the material, the angle after bending often rebounds, resulting in a deviation between the bending angle and the expected angle. In order to improve the bending accuracy, it is necessary to compensate for the rebound.

[0003] Traditional bending dies often have poor results when performing springback compensation operations. Due to the rebound characteristics of the material, after the bending process, the workpiece often rebounds to a certain extent, resulting in a deviation between the bending angle and the design requirements. When dealing with this springback phenomenon, traditional dies lack an effective springback compensation mechanism and cannot accurately compensate for the springback, which affects the precision and quality of the product. In addition, it is also difficult to adjust the bending angle of traditional bending dies. In actual production, it is often necessary to adjust the bending angle according to different product requirements, but the angle adjustment mechanism of traditional dies is relatively complicated, requiring a lot of time and effort to adjust, and the accuracy of the adjustment is difficult to guarantee.

A bending die with a rebound compensation function comprises: a workbench 1, a bending motor 2 is installed at the bottom of the workbench 1, a bending frame 3 is fixedly connected to the driving end of the bending motor 2, a bending plate 4 is fixedly connected to the top of the bending frame 3, a bending rod 5 is fixedly connected to the top of the bending plate 4, a compensation cylinder 6 is installed at the top of the bending plate 4, a compensation push plate 7 is slidably connected to the compensation cylinder 6, a push plate guide groove 8 is provided at the top of the bending plate 4, a fixed die 9 is fixedly connected to the top of the workbench 1, an adjustment die 10 is arranged at the top of the workbench 1, an anti-collision cylinder 11 is installed at the bottom of the workbench 1, an anti-collision telescopic rod 12 is slidably connected to the top of the anti-collision telescopic rod 12, a one-way disc 13 is rotatably connected to the top of the anti-collision telescopic rod 12, and the one-way disc 13 is clamped with the adjustment die 10. The bending die with a rebound compensation function provided by this patent can effectively compensate for the rebound of the material, ensure that the angle after bending is highly consistent with the design requirements, and greatly improve the accuracy and quality of the product.

[0021] The bottom of the workbench 1 is fixedly connected with a limiting gear sleeve 14, the surface of the one-way disc 13 is hinged with a limiting block 15, and a compression spring 16 is fixedly connected between the limiting block 15 and the one-way disc 13. A triangular groove 17 is provided inside the adjusting mold 10, and a reset spring 18 is fixedly connected inside the triangular groove 17. The other end of the reset spring 18 is fixedly connected with a triangular plate 19, and an adjusting rod 20 is fixedly connected to the triangular plate 19. A lifting hole 21 is provided on the one-way disc 13. When the bending angle needs to be adjusted, the adjusting rod 20 is pulled to move the triangular plate 19 upward, and the adjusting rod 21 is adjusted at the same time. 0 slides inside the lifting hole 21, so that the position of the one-way disc 13 does not change, but after rotating the adjusting rod 20, the one-way disc 13 is driven to rotate in the opposite direction, so that the limiting gear sleeve 14 no longer limits the rotation of the one-way disc 13. After rotating to the specified position, the limiting block 15 clamps the inner surface of the limiting gear sleeve 14 again, so that it does not rotate forward, which is convenient for subsequent bending work. At the same time, since the triangular plate 19 can drive the adjusting mold 10 to rotate, it can reach the desired angle position at the same time, put down the adjusting rod 20, and complete the adjustment. The angle of the adjusting mold 10 can be adjusted by pulling and rotating the adjusting rod 20 throughout the process, which is simple and quick.

[0022] A guide plate 22 is fixedly connected to the top of the workbench 1 , and a limiting column 23 is fixedly connected to the top of the workbench 1 . The steel pipe can enter the bending area more quickly through the guide plate 22 and the limiting column 23 .

[0023] A fixed plate 24 is fixedly connected to the right side of the workbench 1, a threaded rod 25 is threadedly connected to the fixed plate 24, a movable plate 26 is rotatably connected to the left side of the threaded rod 25, and a rotating handle 27 is fixedly connected to the right side of the threaded rod 25.

[0026] The working principle of a bending die with springback compensation function provided by the utility model is as follows:

[0027] The steel pipe is placed in the bending area on the workbench 1, clamped between the fixed mold 9 and the adjusting mold 10, the bending motor 2 is started, driving the bending frame 3 to rotate, and the bending disk 4 rotates accordingly, thereby driving the bending rod 5 to bend it. After the bending reaches the specified angle, the folded steel pipe is close to the adjusting mold 10, the anti-collision cylinder 11 is started, and the one-way disc 13 rises. The adjusting mold 10 is raised through the clamping restriction, so that the adjusting mold 10 will not affect the work of the compensation push plate 7 during the subsequent rebound compensation work. After the adjusting mold 10 rises, the compensation cylinder 6 is started, and the pushing distance of the compensation push plate 7 is set according to the material of the steel pipe and the angle difference to offset the elastic recovery that occurs after the material is bent, so as to improve the bending accuracy and consistency.
