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.

[0018] See also Figure 1-4The utility model provides a technical solution: an automatic tool for bending and feeding material, including a lifting frame 1, and four rollers with a locking structure are provided on the bottom plate of the lifting frame 1. The rollers facilitate the flexible movement and positioning of the tool. A lifting plate 2 is provided inside the lifting frame 1, and a push plate 3 is provided inside the lifting plate 2. A U-shaped frame 4 is welded and fixed on the top of the push plate 3. A cylinder 5 is fixedly installed in the middle of the top of the U-shaped frame 4 by bolts. An upper clamping seat 6 driven by the output end of the cylinder 5 is provided inside the U-shaped frame 4, and a lower clamping seat 7 is fixedly installed on the top of the push plate 3 by screws. Several groups of corresponding clamping ports are provided on the corresponding sides of the upper clamping seat 6 and the lower clamping seat 7. The clamping port is an arc-shaped structure, and a lifting mechanism 8 is provided on the outside of one side of the lifting plate 2. The bottom of 2 is provided with a pushing mechanism 9 for pushing the push plate 3 to move laterally. The corresponding arc-shaped clamping openings of the upper clamping seat 6 and the lower clamping seat 7 of this structure can be adaptively adjusted by the cylinder 5 to ensure the stable clamping of tubular blanks of different diameters, so as to improve the versatility and precision control of processing, and the lifting mechanism 8 can drive the lifting plate 2 to move up and down in the lifting frame 1 to smoothly lift the tubular blank to the worktable height of the bending machine, and the pushing mechanism 9 can drive the push plate 3 to move laterally back and forth inside the lifting plate 2 to send the blank to the predetermined position of the bending opening, thereby forming a mechanism that can both vertically lift and horizontally push the blank, realizing the automation of the entire process of receiving, lifting, positioning and feeding the tubular blank into the bending machine, significantly improving the efficiency and accuracy of loading, and improving To solve the problems of high labor intensity, low efficiency and poor processing consistency in traditional manual loading, the clamping openings on the upper clamping seat 6 are provided with elastic clamps 61 with an arc-shaped structure. The elastic clamps 61 are made of spring steel or an alloy material with good elastic memory effect, which ensures a firm and soft clamping of the tubular blank and avoids material damage during the clamping process. Both ends of the elastic clamp 61 are provided with limit shafts 62, and the connection between the limit shaft 62 and the elastic clamp 61 is movably connected by a pin shaft, and both sides of the edge of the clamping opening of the upper clamping seat 6 are welded and fixed with limit sleeves 63, and the limit shaft 62 is movably inserted into the interior of the limit shaft 62. The elastic clamp 61 of this structure and the limit shaft 62 and the limit sleeve 63 matched therewith together constitute a The adaptive clamping structure, the elastic clamp 61 can freely expand and contract within a limited range, which not only realizes the adaptive clamping of pipes with different diameters, but also ensures the appropriate and uniform distribution of the clamping force, thereby improving the clamping stability and processing accuracy. An elastic pad 64 is provided between the back side of the elastic clamp 61 and the inner wall of the clamping opening of the upper clamp seat 6. The elastic pad 64 can be made of highly elastic materials such as rubber or polyurethane, and the elastic pad 64 is an arc-shaped structure. The elastic clamp 61 of this structure can not only further improve the clamping stability of the tubular blank and prevent sliding through the buffering characteristics of the elastic pad 64, but also effectively reduce the damage that may be caused to the surface of the pipe during the clamping process, thereby protecting its surface finish. The pushing mechanism 9 includes a push rod 91, a connecting rod 92 and a hydraulic push rod 93.The push rods 91 are symmetrically fixed on both sides of the bottom of the push plate 3 and pass through the outside of the bottom end of the lifting plate 2. The lifting plate 2 is symmetrically provided with horizontal openings that cooperate with the push rod 91 structure. The connecting rod 92 is connected and fixed between the bottom ends of the push rods 91, and the hydraulic push rod 93 is fixed in the middle of the bottom of the lifting plate 2, and the output end of the hydraulic push rod 93 is fixedly connected to the middle of the connecting rod 92. When the hydraulic push rod 93 is working, its linear pushing effect is transmitted to the push rods 91 on both sides through the connecting rod 92. The push rod 91 slides smoothly in the horizontal openings at the bottom of the lifting plate 2, thereby driving the push plate 3 to move horizontally. This ensures that the blank can be accurately and smoothly pushed to the specified position of the bending machine while being firmly clamped by the upper clamping seat 6 and the lower clamping seat 7, greatly improving the automation level and operation accuracy of loading, and also reducing the intensity of manual operation. The lifting mechanism 8 includes a motor 81, a screw rod 82 and a threaded sleeve 83. The screw rod 82 passes through two support blocks Fixed to one side of the outside of the lifting frame 1, both ends of the screw rod 82 are connected to the inner side of the support block through bearings, and the motor 81 is fixed to the support block at the top of the screw rod 82 by screws. The threaded sleeve 83 is sleeved on the outside of the screw rod 82 through a threaded structure, and one side of the threaded sleeve 83 is fixedly connected to one side of the lifting plate 2 through a connecting block. A guide column 10 is provided on the other side of the outside of the lifting frame 1, and the external movable sleeve of the guide column 10 is provided with a movable sleeve 11, and one side of the movable sleeve 11 is fixedly connected to the other side of the lifting plate 2 through a connecting piece. After the motor 81 of this structure is started, it can drive the threaded sleeve 83 to move linearly, and then drive the lifting plate 2 up and down. At the same time, the parallelogram mechanism composed of the guide column 10 and the movable sleeve 11 ensures the stability and stability of the lifting plate 2 during the vertical lifting process, thereby ensuring that the tubular blank remains stable during the process of lifting to the height of the bending machine worktable, avoiding shaking or tilting, and improving the accuracy and safety of loading.

[0019] Working principle: When using the automatic tool for bending and loading, first start the motor 81 of the lifting mechanism 8, and rotate to drive the screw rod 82 to rotate. The threaded sleeve 83 outside the screw rod 82 moves up and down along the thread, thereby driving the lifting plate 2 to lift synchronously. At the same time, the mechanism composed of the guide column 10 and the movable sleeve 11 ensures the stability of the lifting process. When loading is required, the cylinder 5 works to push the upper clamping seat 6 up and down. Through the cooperation of the elastic clamp 61 and the lower clamping seat 7, tubular blanks of different diameters are adaptively clamped. Here, the limit shaft 62 and the limit sleeve 63 ensure appropriate clamping force. Then start the hydraulic push rod 93, and its linear thrust is transmitted to the push rods 91 on both sides through the connecting rod 92. The push rod 91 slides in the horizontal opening of the lifting plate 2, and the push plate 3 moves back and forth accordingly, and finally the firmly clamped tubular blank is accurately pushed to the predetermined position of the bending machine. The entire loading process integrates the cooperation of vertical lifting and horizontal pushing, realizes automatic loading, and thus completes a series of tasks.
