[0002] Long, straight workpieces are generally made of metal and have a wide range of applications. When the ends of long, straight workpieces need to be bent, a bending machine can be used for processing. Currently, the loading and unloading racks of bending machines are generally installed on both sides of the bending machine. This installation greatly increases the space occupancy rate and places high demands on the installation in the workshop. Furthermore, many loading and unloading racks are currently fixed to the base and cannot be adjusted, resulting in low flexibility. Therefore, an improved technology is urgently needed to solve this problem existing in the current technology. Summary of the Invention

[0014] Please see Figure 1-4 This utility model provides a technical solution: a loading and unloading rack for long straight plate workpieces, including a side frame, a stacking rack 7 and an unloading rack 8. There are two side frames, and the stacking rack 7 and the unloading rack 8 are movably arranged between the two side frames. The side frame includes a lower support frame 1 and an upper support frame 2. The upper support frame 2 is located on the upper surface of the lower support frame 1. The inner side of the upper support frame 2 is open. The upper surface of the upper support frame 2 is provided with two upper guide rails 3 and one upper rack 4 along the length direction. The upper surface of the lower support frame 1 is provided with two lower guide rails 5 and one lower rack 6 along the length direction. Several fixing plates 15 are provided at the bottom of the lower support frame 1 to connect the lower support frame 1 to the ground or base of the installation area with bolts. Limit blocks 20 are provided at both ends of the upper guide rails 3 and the lower guide rails 5 to limit the upper slide 9 and the lower slide 12 and prevent them from falling off the guide rails. The stacking rack 7 is provided with upper slide seats 9 at both ends. The bottom of the upper slide seat 9 is slidably connected to the upper guide rail 3 via a slider. The upper slide seat 9 is provided with an upper servo motor 10. The output shaft of the upper servo motor 10 is provided with a first gear 11. The first gear 11 meshes with the corresponding upper rack 4. The stacking rack 7 is provided with a number of first support plates 16. A number of dividing columns 17 are provided on the upper surface of the support plates. The first support plates 16 are used to support the rods, and the dividing columns 17 are used to separate the rods for stacking. The discharge rack 8 is provided with sliding seats 12 at both ends. The bottom of the sliding seats 12 is slidably connected to the lower guide rail 5 through a slider. The sliding seats 12 are provided with a lower servo motor 13. The output shaft of the lower servo motor 13 is provided with a second gear 14. The second gear 14 meshes with the corresponding lower rack 6. The discharge rack 8 is movably positioned above the stacking rack 7. The upper surface of the discharge rack 8 is provided with several second support plates 18. The two ends of the second support plates 18 are provided with limit plates 19. The second support plates 18 are used to support the long straight plate workpiece after bending at both ends. The limit plates 19 prevent the long straight plate workpiece from falling.

[0015] Installation method and operating principle: First, install the lower guide rail 5 and lower rack 6 on the upper surface of the lower support frame 1. Install the lower servo motor 13 on the sliding seats 12 at both ends of the discharge rack 8. The output shaft of the lower servo motor 13 passes through the sliding seats 12 and is fitted with the second gear 14. Then, slide the sliding seats 12 at both ends of the discharge rack 8 to the lower guide rail 5 via sliders. At this time, the second gear 14 meshes with the lower rack 6. Install the upper support frame 2 above the lower support frame 1. Install the upper guide rail 3 and upper rack 4 on the upper surface of the upper support frame 2. Install the upper servo motor 10 on the upper sliding seats 9 at both ends of the stacking rack 7. The output shaft of the upper servo motor 10 passes through the upper sliding seats 9 and is fitted with the first gear 11. Then, slide the upper sliding seats 9 at both ends of the stacking rack 7 to the upper guide rail 3 via sliders to complete the installation. During operation, the rods are stacked on the stacking rack 7 and separated by the dividing columns 17. The stacking rack 7 moves to a predetermined position, where the rods are clamped and lifted by the suspension gripper mechanism and moved to the bending machine. After bending by the bending machine, the bent rods are lifted again by the suspension gripper mechanism and then moved to the discharge rack 8 and released. At this point, both ends of the rods are bent and hang down naturally, completing the stacking and discharge of the rods. During the feeding and discharging process, the discharge rack 8 moves along the lower guide rail 5 via the lower servo motor 13, the second gear 14, and the lower rack 6. Each time material is discharged, the discharge rack 8 moves a distance equal to the thickness of a straight rod. The stacking rack 7 moves along the upper guide rail 3 via the upper slide 9 via the upper servo motor 10, the first gear 11, and the upper rack 4. When the discharge rack 8 stacks a predetermined number of processed rods, it moves backward to the outermost position, and the push rack 7 moves inward. When loading, the stacking rack 7 moves outward, and the discharge rack 8 moves inward. This utility model has a reasonable structure. The side frame consists of a lower support frame 1 and an upper support frame 2, forming a two-layer structure. The stacking rack 7 is slidably connected at both ends to the upper guide rail 3 on the upper surface of the upper support frame 2 via upper sliding seats 9. The discharge rack 8 is slidably connected at both ends to the lower guide rail 5 on the upper surface of the lower support frame 1 via lower sliding seats 12. Furthermore, the upper sliding seats 9 at both ends of the stacking rack 7 engage with the upper rack 4 on the upper surface of the upper support frame 2 via an upper servo motor 10 and a first gear 11. The lower sliding seats 12 at both ends of the discharge rack 8 engage with the upper rack 4 on the upper surface of the lower support frame 1 via a lower servo motor 13 and a second gear 14. The end rack 4 is engaged, enabling the lateral movement of the stacking rack 7 and the discharge rack 8, thus facilitating the unloading of materials from the stacking rack 7 and the unloading of materials from the discharge rack 8, greatly improving flexibility and convenience. Furthermore, both the stacking rack 7 and the discharge rack 8 are connected to the two side racks of the same group, significantly saving space. At the same time, when the suspension gripper mechanism picks up materials, the stacking rack 7 moves to adapt to the clamping position. When discharging materials through the suspension gripper mechanism after bending, the discharge rack 8 moves to adapt to the unloading position. Moreover, for the suspension gripper mechanism, only the feeding clamping position, clamping height, and unloading position need to be set, making operation more convenient.
