Its main function is to bend, fold, or curve the sheet materials into the required shapes. This kind of machine is widely used in industrial manufacturing and the construction industry for producing various types of parts, components, and structures.

[0003] When the existing automatic bending machine bends the sheet material, generally, the sheet material is supported manually for the bending operation. When the sheet material is large, its own weight will also increase, and it is quite laborious to support it only manually, increasing the physical consumption of the staff. Moreover, when the existing sheet material is bent, most of them do not have a structure for preventing the sheet material from being scratched. As a result, when the bottom end of the sheet material moves on the inner wall of the bending seat during the bending process by the bending head, it will cause scratches to the bottom end of the sheet material. For this reason, a device for preventing sheet materials from being scratched in a bending machine is proposed to solve the above problems. Summary of the Utility Model

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Refer to Figures 1 - 3 An embodiment provided by the present utility model: A device for preventing sheet scratching in a bending machine includes a machine body 1. A control panel 2 is provided at the top of the outer wall of the machine body 1. The control panel 2 is a prior art, and signals are transmitted to the electric telescopic rod 3 through the control buttons on its surface, so as to control the telescopic movement of the electric telescopic rod 3 to drive the bending seat 6 by the fixed seat 4 to bend the sheet. Two groups of electric telescopic rods 3 are fixedly connected to the surface of the machine body 1. The bottom end of the outer wall of the electric telescopic rod 3 is fixedly connected to a fixed seat 4. A bending head 5 is detachably installed on the surface of the fixed seat 4. Mounting seats are provided on the surfaces of the fixed seat 4 and the bending head 5, and bolts are used to connect and fix the fixed seat 4 and the bending head 5, so that the bending head 5 can stably descend to bend the sheet. A bending seat 6 is fixedly connected to the surface of the inner side wall of the machine body 1. An anti-scratch component 7 is provided inside the bending seat 6.

[0031] Refer to Figures 1 - 3The surface of the machine body 1 is provided with a support assembly 8, and the support assembly 8 includes a fixed block 81, which is fixedly connected to the surface of the inner side wall of the machine body 1, and the outer wall of the fixed block 81 is fixedly connected to the outer wall of the bending seat 6. The inner wall of the fixed block 81 is slidably connected with a sliding plate 82, and the inner wall of the fixed block 81 is provided with a cavity, and sliders are provided on both sides of the sliding plate 82, so that the sliding plate 82 can only move on the inner wall of the fixed block 81 and cannot be separated from its inner wall. The bottom end of the outer wall of the sliding plate 82 is fixedly connected with two sets of moving The moving wheel 83 has a rod body at the top of the outer wall of the moving wheel 83 and a wheel at the bottom, so that the sliding plate 82 can be supported after the inner wall of the fixed block 81 is extended and unfolded. A guide groove is provided at the bottom end of the fixed block 81, and the moving wheel 83 is slidably connected to the inner wall of the empty groove. By providing an empty groove at the bottom end of the fixed block 81, the sliding plate 82 will drive the moving wheel 83 to move synchronously when it is pulled outward, thereby avoiding the moving wheel 83 being blocked by the fixed block 81 when it moves with the sliding plate 82.

[0032] Reference Figures 2 - 3 The inner wall of the sliding plate 82 is elastically connected to the rotating rod 84 by a volute spring 86, one end of the volute spring 86 is fixedly connected to the outer wall of the bottom end of the rotating rod 84, and the other end of the volute spring 86 is fixedly connected to the bottom end of the inner wall of the sliding plate 82. The function of the volute spring 86 is to automatically reset the position of the rotating rod 84 after rotation, and the volute spring 86 drives the card block 87 to be elastically supported in the downward direction by the volute spring 86. One end of the rotating rod 84 is fixedly connected to the card block 87, and the other end of the rotating rod 84 is fixedly connected to the baffle 85. The surface of the baffle 85 is provided with a handle, which can drive the baffle 85, the rotating rod 84 and the card block 87 to rotate synchronously. The bottom end of the inner wall of the fixed block 81 is provided with a plurality of groups of sliding grooves, and the card block 87 contacts the inner wall of the sliding groove, and the mutual contact between the two The locking plate 87 is in contact with the inner wall of the fixed block 81, thereby fixing the sliding plate 82 at multiple positions where the inner wall of the fixed block 81 moves outward, and the shape of the slide groove is a quarter circle of the block 87 rotating around the center point of the rotating rod 84, so that the block 87 can slide on the inner wall of the fixed block 81 when rotating, and the block 87 is slidably connected to the inner wall of the sliding plate 82. A notch is provided at the corresponding block 87 position of the sliding plate 82, so that the block 87 can move on the inner wall of the sliding plate 82, thereby canceling the fixation between the sliding plate 82 and the fixed block 81, and the inner side wall of the baffle 85 contacts the outer wall of the sliding plate 82. The contact between the two can push the plate on the surface of the sliding plate 82 through the baffle 85 after the plate is placed, thereby preventing the plate from tilting and moving on its surface.

[0033] Reference Figure 1 and Figure 4, the scratch-proof component 7 includes a guide block 71. The guide block 71 is elastically connected to the inner wall of the bending seat 6 through a limit spring 72. One end of the limit spring 72 is fixedly connected to the outer wall of the guide block 71, and the other end of the limit spring 72 is fixedly connected to the inner wall of the bending seat 6. The function of the limit spring 72 is that after the contact wheel 73 is squeezed by the plate, it can apply elastic support to the contact wheel 73. The surface of the guide block 71 is rotatably connected with a contact wheel 73. The contact wheel 73 is made of a hard material, and a rubber layer is attached to its surface, so as to reduce the scraping of the bottom end of the plate. The guide block 71 is slidably connected to the inner wall of the bending seat 6, and the contact wheel 73 is slidably connected to the inner wall of the bending seat 6. When the plate is bent by the bending head 5 on the inner wall of the bending seat 6, the outer wall of the plate will squeeze multiple contact wheels 73, so that the contact wheels 73 drive the guide block 71 to move on the inner wall of the bending seat 6, so that the inner wall of the bending seat 6 presents a V shape for the plate bending. At the same time, the bottom end of the plate is also protected.

[0034] Working principle: When processing the plate, first, the position of the sliding plate 82 can be moved according to the length of the plate. By grasping the handle on the outer wall of the baffle 85, the baffle 85 is rotated to drive the rotating rod 84 and the block 87 on the surface of the rotating rod 84 to rotate synchronously. And during the rotation of the rotating rod 84, the scroll spring 86 will be elastically compressed, and the block 87 will also disengage from the inner wall of the chute at the current position of the fixed block 81 and move on the inner wall of the sliding plate 82. At this time, the baffle 85 will also rotate to be flush with the surface of the sliding plate 82. At this time, the sliding plate 82 can be removed from the inner wall of the fixed block 81, and the sliding plate 82 is supported by the moving wheel 83. When adjusted to the appropriate position, the baffle 85 is released, and the rotating rod 84 will be elastically acted on by the scroll spring 86 to restore it and the baffle 85 and the block 87 to the initial position, so that the block 87 will contact the inner wall of the chute at the current position of the inner wall of the fixed block 81, so as to fix the position of the sliding plate 82 after extending in the inner wall of the fixed block 81. Therefore, during the process of bending the plate, there is no need for manual lifting of the plate.

[0035] Meanwhile, during the process of bending the sheet metal through the folding elbow 5, the sheet metal will move towards the middle in the V-shaped groove of the bending seat 6. As a result, when the sheet metal deforms according to the V-shaped groove, its outer wall will come into contact with the outer walls of multiple contact wheels 73. Thus, the bottom end of the bent part of the sheet metal is protected by the multiple contact wheels 73, preventing scratches from being generated at the bottom during the friction with the inner wall of the bending seat 6. At the same time, when the contact wheels 73 come into contact with the sheet metal, they will drive the guide blocks 71 to move on the inner wall of the bending seat 6, and the limiting springs 72 will be elastically compressed. Therefore, when the sheet metal is not being bent, the multiple contact wheels 73 will completely enter the inner wall of the bending seat 6, enabling the sheet metal to make complete contact with the inner wall of the bending seat 6. After the processing is completed, the multiple guide blocks 71 will be elastically actuated by the limiting springs 72 and drive the contact wheels 73 to return to their initial positions.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
