[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0022] Please refer to the appendix. Figures 1-6 This utility model provides a support bar end stamping and bending device for stamping and bending support bar 1. Symmetrical through holes 2 are provided on support bar 1 (e.g., ...). Figure 1 and Figure 2 As shown), it includes a base plate 3, with support rods 4 symmetrically and vertically fixed on the rear side of the top of the base plate 3, a top plate 5 horizontally fixed at the top of the two support rods 4, a base 6 fixed on the top of the base plate 3, a rectangular hole 7 opened on the top of the base 6, an automatic feeding component fixed inside the base 6, a positioning clamping component fixed between the top plate 5 and the automatic feeding component, a first stamping and bending component fixed on the top plate 5, and a second stamping and bending component fixed on the top of the base plate 3.

[0023] The positioning and clamping assembly includes a vertically arranged first electric push rod 8, the bottom of which is fixed to the top of the top plate 5. A first connecting plate 9 is fixed to the bottom of the output shaft of the first electric push rod 8. An upper clamping block 10 is fixed to the bottom of the first connecting plate 9. The upper clamping block 10 has symmetrically opened slots 11 at its bottom. Specifically, when the first electric push rod 8 is running, it can drive the upper clamping block 10 to rise and fall through the first connecting plate 9, thereby pressing and fixing the support bar 1.

[0024] The automatic feeding assembly includes a vertically arranged second electric push rod 12. The bottom of the second electric push rod 12 is fixed to the top of the base plate 3. The second electric push rod 12 is located inside the base 6. The top of the output shaft of the second electric push rod 12 is fixed to a second connecting plate 13. The top of the second connecting plate 13 is fixed to a lower clamping block 14. The lower clamping block 14 vertically penetrates the rectangular hole 7. The top of the lower clamping block 14 is symmetrically fixed with positioning pins 15. The two positioning pins 15 are located directly below the two opening slots 11. The two positioning pins 15 can vertically penetrate the through hole 2. Specifically, when the second electric push rod 12 is running, it can drive the lower clamping block 14 to rise and fall through the second connecting plate 13. With the use of the upper clamping block 10, the support bar 1 can be effectively clamped and fixed. Under the positioning action of the positioning pins 15, the support bar 1 can be effectively prevented from shifting during the stamping and bending process. Thus, the stability of the positioning and clamping of the support bar 1 can be greatly improved during the stamping and bending process.

[0025] The first stamping and bending assembly includes a vertically arranged third electric push rod 16. The bottom of the third electric push rod 16 is fixed to the top of the top plate 5. The third electric push rod 16 is located behind the first electric push rod 8. The bottom end of the output shaft of the third electric push rod 16 is fixed with a third connecting plate 17. The bottom of the third connecting plate 17 is fixed with an upper stamping block 18. Specifically, when the upper clamping block 10 and the lower clamping block 14 clamp and fix the support bar 1, the third electric push rod 16 runs and drives the upper stamping block 18 to move down through the third connecting plate 17, performing a stamping and bending operation on the rear side of the support bar 1 itself.

[0026] The second stamping and bending assembly includes two vertically arranged support plates 19. The bottoms of the two support plates 19 are symmetrically fixed to the top sides of the base plate 3. A fourth electric push rod 20 is longitudinally fixed to the top of each support plate 19. A side stamping block 21 is fixed to the front end of the output shaft of each fourth electric push rod 20. Specifically, when the rear side of the support bar 1 is stamped and bent, the fourth electric push rod 20 runs, driving the side stamping block 21 to move forward, so that the two ends of the support bar 1 can be stamped and bent. That is, the device can have the function of stamping and bending the support bar 1 itself and its two ends. After the stamping and bending is completed, when the second electric push rod 12 runs and drives the lower clamping block 14 to move down and be stored inside the base 6, the stamped and bent support bar 1 completes the automatic unloading and feeding operation. That is, the device can also conveniently unload and feed the stamped and bent support bar 1, which is convenient to use.

[0027] It should be noted that this device is electrically connected to an external controller and 220V AC mains power. The controller can be an existing technology device such as a computer. In this invention, the precise control principle of the first electric actuator 8, the second electric actuator 12, the third electric actuator 16, and the fourth electric actuator 20 is to achieve motion conversion through the mechanical cooperation of a servo motor and a lead screw. The status is monitored in real time with the help of devices such as encoders, and finally the controller dynamically adjusts the output according to the deviation, thereby achieving precise control of position, speed, and force within the millimeter or even micrometer range.

[0028] The usage process of this utility model is as follows: During use, the operator first places the support strip 1 to be stamped and bent on top of the lower clamping block 14, aligning the two through holes 2 on the support strip 1 with the two positioning pins 15 penetrating the top of the lower clamping block 14. Then, the first servo motor 8 is started to control the upper clamping block 10 to move downwards, coordinating with the use of the lower clamping block 14 to position and clamp the support strip 1. Then, the third electric push rod 16 operates, driving the upper stamping block 18 downwards via the third connecting plate 17, thus stamping and bending the rear side of the support strip 1. When the support bar 1 is bent by stamping, the fourth electric push rod 20 moves, driving the side stamping block 21 forward, thus performing stamping and bending operations on both ends of the support bar 1. In other words, the device can perform stamping and bending operations on the support bar 1 itself and both ends. After the stamping and bending is completed, the second electric push rod 12 moves, driving the lower clamping block 14 to move down and be stored inside the base 6. The stamped and bent support bar 1 completes the automatic unloading and feeding operation. In other words, the device can also conveniently unload and feed the stamped and bent support bar 1, making it convenient to use.

[0029] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art can modify this utility model or modify it into an equivalent technical solution using the technical solution described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solution of this utility model are within the scope of protection claimed by this utility model.
