[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-2 This utility model provides an embodiment of a bending machine for processing shock absorber plates for new energy electric tricycles, including a processing table 1. A base 2 is fixedly connected to the upper surface of the processing table 1. A through groove 3 is opened at the center of the upper surface of the base 2. A bending component 4 is provided on the rear side of the upper surface of the processing table 1. The bending component 4 includes a low-speed stepper motor and a spindle-shaped cam. When the low-speed stepper motor starts, it can drive the spindle-shaped cam to rotate. A plate 5 is provided above the base 2. A bolt 6 is threadedly connected inside the plate 5. A clamping adapter is threadedly connected to the upper end of the bolt 6. The clamping adapter cooperates with the bolt 6 to clamp and fix the plate 5. The bottom surface of the spindle-shaped cam is in contact with the upper surface of the clamping adapter. When the low-speed stepper motor starts and drives the spindle-shaped cam to rotate, it will squeeze the clamping adapter downward, causing the plate 5 to undergo elastic deformation under the pressure of the spindle-shaped cam and bend downward. This is a prior art in this field and will not be described in detail here.

[0033] Reference Figures 3-4A telescopic rod 7 is fixedly connected to the upper surface of the processing table 1. A return spring 8 is fixedly connected inside the telescopic rod 7. The top end of the return spring 8 is fixedly connected to the top inner surface of the telescopic rod 7, and the bottom end of the return spring 8 is fixedly connected to the bottom inner surface of the telescopic rod 7. When the upper end of the telescopic rod 7 is pressed and moves downward, it will squeeze the return spring 8, causing the return spring 8 to compress and generate elastic potential energy. When the pressure on the telescopic rod 7 is removed, the telescopic rod 7 will return to its original position under the action of the elastic potential energy of the return spring 8. A support block 9 is fixedly connected to the upper end of the telescopic rod 7. A hexagonal groove 10 is opened at the center of the upper surface of the support block 9. The bolt 6 is connected to the hexagonal groove 10. The internal insertion of the bolt 6 involves inserting the bottom end of the bolt 6 into the hexagonal groove 10 after the plate 5 is placed above the base 2. This limits the movement of the bolt 6 and the plate 5, ensuring that the plate 5 is stably placed at the center of the base 2. When the bending component 4 starts bending the plate 5, as the plate 5 gradually bends downward, the movement of the plate 5 is guided and limited by the cooperation between the support block 9 and the bolt 6. This ensures that the center of the plate 5 can only move in a straight line in the up and down direction, preventing the plate 5 from shifting in the left and right directions during the bending process. This would cause the curvature of the left and right ends of the plate 5 to be inconsistent, affecting the bending and forming effect of the damping plate.

[0034] A snap-fit ​​box 11 is fixedly connected to the outer side of the upper end of the telescopic rod 7. When the telescopic rod 7 is compressed or extended, the snap-fit ​​box 11 can move synchronously. A snap-fit ​​unit is provided on the inner wall surface of the through groove 3. The snap-fit ​​unit includes a fixed box 111. A snap-fit ​​spring 112 is fixedly connected to the inner surface of the fixed box 111 away from the telescopic rod 7. A snap-fit ​​block 113 is fixedly connected to the end of the snap-fit ​​spring 112 near the telescopic rod 7. When the snap-fit ​​block 113 moves into the fixed box 111, it can squeeze the snap-fit ​​spring 112, causing the snap-fit ​​spring 112 to compress and generate elastic potential energy. The upper end of the snap-fit ​​block 113 near the telescopic rod 7 has a chamfered structure. 113 is inserted into the interior of the fixing box 111. The end of the locking block 113 away from the locking spring 112 is locked into the interior of the locking box 11. At this time, the locking block 113 can lock and fix the upper end of the telescopic rod 7. The upper surface of the fixing box 111 is provided with a moving groove 114. The moving groove 114 is slidably connected to the interior of the moving groove 114. The bottom end of the connecting block 115 is fixedly connected to the upper surface of the locking block 113. The operator can pull the locking block 113 through the connecting block 115, so that the locking block 113 can move linearly in the left and right directions, thereby allowing the locking block 113 to quickly leave the interior of the locking box 11 and release the locking and fixing of the upper end of the telescopic rod 7.

[0035] As the plate 5 gradually bends, it compresses the support block 9, causing the support block 9 to move downwards and compressing the telescopic rod 7, causing the upper end of the telescopic rod 7 to move downwards. At this time, the snap-fit ​​box 11 will move synchronously. During the movement of the snap-fit ​​box 11, it will press against the inclined surface of the snap-fit ​​block 113, causing the snap-fit ​​block 113 to enter the interior of the fixing box 111. After the plate 5 is bent, the snap-fit ​​block 113 will be aligned with the interior of the snap-fit ​​box 11. At this time, the snap-fit ​​block 113 will move into the interior of the snap-fit ​​box 11 under the action of the elastic potential energy of the snap-fit ​​spring 112, snap-fitting and fixing the upper end of the snap-fit ​​box 11 and the telescopic rod 7, thereby canceling the elastic potential energy of the return spring 8. This prevents the elastic potential energy of the return spring 8 from continuously acting on the plate 5 when the plate 5 is bent and shaped, which would increase the internal stress of the plate 5 and affect the forming effect and service life of the plate 5.

[0036] Reference Figure 3 and Figure 5 The upper surface of the support block 9 has a groove 12. An elastic element 13 is fixedly connected to the bottom surface of the groove 12. A heat insulation plate 14 is fixedly connected to the upper end of the elastic element 13. The heat insulation plate 14 is inserted into the groove 12. An electric heating block 15 is fixedly connected to the upper surface of the heat insulation plate 14. When the electric heating block 15 moves downward, it will squeeze the elastic element 13 through the heat insulation plate 14, causing the elastic element 13 to compress and generate elastic potential energy. The upper surface of the electric heating block 15 is in contact with the bottom surface of the plate 5. When the plate 5 is placed above the base 2 and the bottom of the bolt 6 is inserted into the hexagonal groove 10, the upper surface of the electric heating block 15 is in contact with the bottom surface of the plate 5. At this time, electricity can be supplied to the electric heating block 15, causing the electric heating block 15 to generate heat and bend the plate 5. Preheating is performed to improve the ductility of the plate 5, making it easier to bend. As the plate 5 gradually bends, the electric heating block 15 will move accordingly under the elastic potential energy of the elastic element 13, avoiding obstruction to the bending of the plate 5. At the same time, when the electric heating block 15 is heating, the heat insulation plate 14 can isolate the generated heat, preventing the heat from being transferred to the elastic element 13, which would cause the elastic element 13 to overheat and affect its use. A heat dissipation vent 16 is provided on the side of the groove 12 away from the hexagonal groove 10. The heat dissipation vent 16 passes through the support block 9, allowing the space where the elastic element 13 is located to circulate with the outside air for heat dissipation, preventing the space where the elastic element 13 is located from being sealed, which would cause heat to accumulate in the sealed space and cause the elastic element 13 to overheat.

[0037] Working principle: The plate 5 is placed on the base 2, and the bottom end of the bolt 6 is inserted into the hexagonal slot 10. Through the cooperation of the support block 9, the hexagonal slot 10, and the bolt 6, the movement of the center of the plate 5 is limited, preventing the plate 5 from shifting in the left or right direction during bending, which would affect the bending and forming effect of the plate 5. Then, the bending component 4 is activated to bend the plate 5. As the plate 5 gradually bends, it will squeeze the support block 9 and the telescopic rod 7, causing them to move downwards, and compress the return spring 8 to generate elastic potential energy, preventing damage to the bending of the plate 5. When the plate 5 is bent and shaped, the locking block 113 will be locked into the locking box 11 under the elastic potential energy of the locking spring 112, locking and fixing the upper end of the telescopic rod 7, preventing the elastic potential energy of the return spring 8 from continuously acting on the plate 5, which would affect the shaping of the plate 5. When the bottom end of the bolt 6 is inserted into the hexagonal groove 10, the upper end of the electric heating block 15 will be in contact with the bottom surface of the plate 5. At this time, the electric heating block 15 can be powered to generate heat, preheating the bent part of the plate 5, improving the ductility of the plate 5, and making it easier to bend.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
