Description
Technical Field
[0001] This utility model relates to the field of metal processing technology, specifically to a metal bending machine with an anti-dropping structure. Background Technology
[0002] A bending machine is an industrial machine used to bend metal or plastic materials. It is commonly used in the manufacture of metal products, pipes, fittings, steel structures, and other products. A bending machine typically consists of a machine body, bending dies, and a control system. During operation, the sheet metal or pipe to be processed is placed on the machine tool. Then, by adjusting the fixtures and dies on the machine tool, the material is bent to the required angle and shape. The control system is usually set through a control panel to set the bending angle and speed to ensure the accuracy and stability of the bending process. Bending machines are widely used in the automotive, aerospace, construction, electronics, and furniture industries.
[0003] According to Chinese patent CN221870016U, a bending machine with anti-deviation mechanism is proposed. In this device, after the metal material is placed on the worktable, the hydraulic press is activated. The conical block on the hydraulic press moves forward and abuts against the roller at the end of the Z-shaped rod. At this time, the two sets of Z-shaped rods can adjust the clamping diameter. Then the hydraulic press is turned off, and the Z-shaped rods clamp and fix the metal material on the worktable, so that deviation will not occur during bending.
[0004] However, this patent still has some shortcomings. In the process of bending metal parts, some metal parts with uneven surfaces are often encountered. In the process of clamping and fixing the metal by the clamping rods in this device, since the surfaces of the two clamping rods are smooth planes, they cannot stably clamp and fix the uneven metal parts. In the process of clamping and fixing the uneven metal parts, when bending the metal parts, the metal parts are prone to loosening and falling off, thus affecting the stability of the bending process. To this end, we propose a metal part bending machine with an anti-fall-off structure. Utility Model Content
[0005] The purpose of this invention is to provide a metal bending machine with an anti-fall-off structure, which solves the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a metal bending machine with an anti-fall-off structure, comprising a mounting plate and a positioning component disposed on the top of the mounting plate. The positioning component includes a rectangular column disposed above the mounting plate. A first L-shaped plate is fixedly connected to the top side wall of the rectangular column. A sleeve is fixedly connected to the bottom of the inner wall of the first L-shaped plate. A spring is fixedly connected to the bottom of the inner wall of the sleeve. A pressing rod is fixedly connected to the other end of the spring. A limit block is slidably connected to one side inner wall of the first L-shaped plate. A second L-shaped plate is fixedly connected to the top of the limit block. A connecting frame is fixedly connected to the top of the rectangular column. An electric push rod is fixedly connected to the top of the inner wall of the connecting frame. The output end of the electric push rod is fixedly connected to the top of the second L-shaped plate. By setting the positioning component, it is convenient to press the outer wall of the metal part by multiple pressing rods, thereby achieving clamping and fixing of metal parts with uneven surfaces, thus improving the stability of the metal part during the bending process.
[0007] Preferably, the positioning assembly further includes a rectangular frame fixedly connected to the top of the mounting plate. A crossbar is fixedly connected to the inner wall of the rectangular frame, and a displacement block is slidably connected to the outer wall of the crossbar. The top of the displacement block is fixedly connected to the bottom of the rectangular column. A support frame is fixedly connected to the top of the mounting plate. A forward / reverse motor is fixedly connected to the inner wall of the top of the support frame. An output shaft is fixedly connected to the output end of the forward / reverse motor. A gear is fixedly connected to the outer wall of the other end of the output shaft. A rack meshes with the outer wall of the gear. A connecting block is fixedly connected to the side wall of the rack. The other end of the connecting block is connected to the rectangular column. The outer wall of the rectangular column is fixedly connected. During the bending process of the metal part, in order to facilitate the adjustment of the clamping distance between the two rectangular columns according to the length of the metal part, the operator turns on the forward and reverse motor to make the output shaft rotate. During the rotation of the output shaft, the gear rotates and meshes with the rack. The gear moves the rectangular column through the connecting block, and the displacement block at the bottom of the rectangular column moves laterally along the outer wall of the crossbar. This makes it easy to adjust the distance between the two rectangular columns and effectively clamp and fix the metal part according to its length.
[0008] Preferably, the top of the mounting plate is further provided with a bending assembly. The bending assembly includes a U-shaped plate fixedly connected to the top of the mounting plate. A drive motor is fixedly connected to the top outer wall of the U-shaped plate. A lead screw is fixedly connected to the output end of the drive motor. The other end of the lead screw is rotatably connected to the inner wall of the U-shaped plate. A sleeve block is threadedly connected to the outer wall of the lead screw. A cylinder is fixedly connected to the bottom of the sleeve block. A bending block is fixedly connected to the output end of the cylinder. By setting the bending assembly, after the metal part is fixed, when it needs to be bent, the operator turns on the cylinder, causing the output end of the cylinder to push the bending block downward, so that the bending block can bend the surface of the metal part. When it is necessary to adjust the bending position of the metal part, the operator turns on the drive motor, causing the lead screw to rotate. During the rotation of the lead screw, the sleeve block will move laterally along the outer wall of the lead screw, thereby driving the bending block to move, thus facilitating the adjustment of the bending position of the metal part.
[0009] Preferably, the bottom of the mounting plate is fixedly connected with four support legs of equal size. The four support legs are fixedly connected at equal intervals at the four corners of the bottom of the mounting plate. By setting four support legs at the bottom of the mounting plate, a stable support function for the mounting plate can be achieved.
[0010] Preferably, the bottom outer wall of the displacement block is adapted to the inner wall of the rectangular frame, and the bottom inner wall of the displacement block is slidably connected to the outer wall of the crossbar. By setting the rectangular frame and the crossbar, it is easy to limit the displacement block during the movement process and make it move smoothly.
[0011] Preferably, the bottom outer wall of the extrusion rod is adapted to the inner wall of the sleeve, and the bottom of the extrusion rod is fixedly connected to one end of the spring.
[0012] Preferably, there are two rectangular columns, both of equal size, symmetrically distributed along the center plane of the rectangular frame. By setting two rectangular columns, the metal part can be clamped and fixed according to its length during the adjustment of the distance between the two rectangular columns, preventing the metal part from falling off during the bending process.
[0013] Preferably, the top of the socket block is slidably connected to the top of the inner wall of the U-shaped plate, and the bottom of the socket block is fixedly connected to the top of the cylinder.
[0014] This invention provides a metal parts bending machine with an anti-detachment structure. This metal parts bending machine with an anti-detachment structure has the following advantages:
[0015] (1) This metal bending machine with an anti-fall-off structure, by setting a positioning component, needs to position the metal part during the bending process to prevent it from falling off. The operator places one end of the metal part to be bent on the side of the first L-shaped plate, so that the end face of the extrusion rod contacts the outer wall of the end face of the metal part. Then, by activating the electric push rod, the output end of the electric push rod pushes the second L-shaped plate downwards, causing the limiting block to slide on the inner wall of the side of the first L-shaped plate. When the second L-shaped plate moves downwards, it causes the sleeve to move, allowing the extrusion rod inside the sleeve to extrude force on the surface of the metal. By setting multiple extrusion rods, surface extrusion can be achieved. Uneven metal parts are clamped and fixed to prevent them from falling off during bending, thus improving the processing efficiency of the device. During the bending process, to facilitate adjustment of the clamping distance between the two rectangular columns according to the length of the metal part, the operator turns on the forward and reverse motor to rotate the output shaft. During the rotation of the output shaft, the gear rotates and meshes with the rack. The gear moves the rectangular columns through the connecting block, causing the displacement block at the bottom of the rectangular column to move laterally along the outer wall of the crossbar. This facilitates adjustment of the distance between the two rectangular columns and effectively clamps and fixes the metal part according to its length.
[0016] (2) The metal bending machine with anti-drop structure, by setting up a bending assembly, after the metal part is fixed, when it needs to be bent, the operator opens the cylinder to cause the output end of the cylinder to push the bending block to move downward, so that the bending block can bend the surface of the metal part. When it is necessary to adjust the bending position of the metal part, the operator opens the drive motor to cause the lead screw to rotate. During the rotation of the lead screw, the sleeve block will move laterally along the outer wall of the lead screw, thereby driving the bending block to move, so as to facilitate the adjustment of the bending position of the metal part.

[0024] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.
[0025] A preferred embodiment of the metal bending machine with an anti-detachment structure provided by this utility model is, for example... Figures 1 to 6As shown: A metal bending machine with an anti-fall-off structure includes a mounting plate 1 and a positioning assembly 31 disposed on the top of the mounting plate 1. The positioning assembly 31 includes a rectangular column 318 disposed above the mounting plate 1. A first L-shaped plate 3111 is fixedly connected to the top side wall of the rectangular column 318. A sleeve 3112 is fixedly connected to the bottom of the inner wall of the first L-shaped plate 3111. A spring 3113 is fixedly connected to the bottom of the inner wall of the sleeve 3112. A pressing rod 3114 is fixedly connected to the other end of the spring 3113. A limit block 3115 is slidably connected to one side inner wall of the first L-shaped plate 3111. A second L-shaped plate 3116 is fixedly connected to the top of the limit block 3115. A connecting frame 3117 is fixedly connected to the top of the rectangular column 318. An electric push rod 3118 is fixedly connected to the top of the inner wall of the connecting frame 3117. The output end of the electric push rod 3118 is fixedly connected to the top of the second L-shaped plate 3116. By setting the positioning assembly 31... During the bending process of metal parts, in order to prevent the metal parts from falling off during bending, it is necessary to position the metal parts. At this time, the operator places one end of the metal part to be bent on the side of the first L-shaped plate 3111, so that the end face of the extrusion rod 3114 contacts the outer wall of the end face of the metal part. Then, by activating the electric push rod 3118, the output end of the electric push rod 3118 pushes the second L-shaped plate 3116 downward, so that the limiting block 3115 slides on the inner wall of the side of the first L-shaped plate 3111. When the second L-shaped plate 3116 moves downward, it will cause the sleeve 3112 to move, so that the extrusion rod 3114 in the sleeve 3112 can extrude the surface of the metal. By setting multiple extrusion rods 3114, it is possible to clamp and fix the metal parts with uneven surfaces, so as to avoid falling off during the bending process and improve the processing effect of the device.
[0026] The positioning assembly 31 also includes a rectangular frame 311 fixedly connected to the top of the mounting plate 1. A crossbar 3110 is fixedly connected to the inner wall of the rectangular frame 311, and a displacement block 319 is slidably connected to the outer wall of the crossbar 3110. The top of the displacement block 319 is fixedly connected to the bottom of the rectangular column 318. A support frame 312 is fixedly connected to the top of the mounting plate 1. A forward and reverse motor 313 is fixedly connected to the inner wall of the top of the support frame 312. An output shaft 314 is fixedly connected to the output end of the forward and reverse motor 313. A gear 315 is fixedly connected to the outer wall of the other end of the output shaft 314. A rack 316 meshes with the outer wall of the gear 315. A connecting block 317 is fixedly connected to the side wall of the rack 316. The other end of the connecting block 317 is connected to the rectangular column. The outer wall of 318 is fixedly connected. During the bending process of the metal part, in order to facilitate the adjustment of the clamping distance between the two rectangular columns 318 according to the length of the metal part, the operator turns on the forward and reverse motor 313 to make the output shaft 314 rotate. During the rotation of the output shaft 314, the gear 315 rotates. During the rotation of the gear 315, it meshes with the rack 316 and moves the rectangular column 318 through the connecting block 317. This causes the displacement block 319 at the bottom of the rectangular column 318 to move laterally along the outer wall of the crossbar 3110, thereby facilitating the adjustment of the distance between the two rectangular columns 318 and effectively clamping and fixing the metal part according to its length.
[0027] A preferred embodiment of the metal bending machine with an anti-detachment structure provided by this utility model is, for example... Figures 1 to 6 As shown: A bending assembly 32 is also provided on the top of the mounting plate 1. The bending assembly 32 includes a U-shaped plate 321 fixedly connected to the top of the mounting plate 1. A drive motor 322 is fixedly connected to the top outer wall of the U-shaped plate 321. A lead screw 323 is fixedly connected to the output end of the drive motor 322. The other end of the lead screw 323 is rotatably connected to the inner wall of the U-shaped plate 321. A sleeve block 324 is threadedly connected to the outer wall of the lead screw 323. A cylinder 325 is fixedly connected to the bottom of the sleeve block 324. A bending block 326 is fixedly connected to the output end of the cylinder 325. By setting the bending assembly 32, bending can be achieved by bending metal... After the component is fixed, when it needs to be bent, the operator turns on the cylinder 325, causing the output end of the cylinder 325 to push the bending block 326 downward, so that the bending block 326 can bend the surface of the metal component. When it is necessary to adjust the bending position of the metal component, the operator turns on the drive motor 322, causing the lead screw 323 to rotate. During the rotation of the lead screw 323, the sleeve block 324 will move laterally along the outer wall of the lead screw 323, thereby driving the bending block 326 to move, so as to facilitate the adjustment of the bending position of the metal component.
[0028] Furthermore, the bottom of the mounting plate 1 is fixedly connected with four support legs 2. The four support legs 2 are of equal size and are fixedly connected at the four corners of the bottom of the mounting plate 1 at equal intervals. By setting four support legs 2 at the bottom of the mounting plate 1, a stable support function for the mounting plate 1 can be achieved.
[0029] Furthermore, the bottom outer wall of the displacement block 319 is adapted to the inner wall of the rectangular frame 311, and the bottom inner wall of the displacement block 319 is slidably connected to the outer wall of the crossbar 3110. By setting the rectangular frame 311 and the crossbar 3110, it is easy to limit the displacement block 319 during the movement process, so that it can move smoothly.
[0030] Furthermore, the bottom outer wall of the extrusion rod 3114 is adapted to the inner wall of the sleeve 3112, and the bottom of the extrusion rod 3114 is fixedly connected to one end of the spring 3113.
[0031] Furthermore, there are two rectangular columns 318, both of equal size, symmetrically distributed along the central plane of the rectangular frame 311. By setting two rectangular columns 318, the metal parts can be clamped and fixed according to their length during the adjustment of the spacing between the two rectangular columns 318, preventing the metal parts from falling off during the bending process.
[0032] In addition, the top of the socket block 324 is slidably connected to the top of the inner wall of the U-shaped plate 321, and the bottom of the socket block 324 is fixedly connected to the top of the cylinder 325.
[0033] Working principle: During the bending process of metal parts, in order to prevent the metal parts from falling off during the bending process, it is necessary to position the metal parts. At this time, the operator places one end of the metal part to be bent on the side of the first L-shaped plate 3111, so that the end face of the extrusion rod 3114 contacts the outer wall of the end face of the metal part. Then, by activating the electric push rod 3118, the output end of the electric push rod 3118 pushes the second L-shaped plate 3116 downward, so that the limiting block 3115 slides on the inner wall of the side of the first L-shaped plate 3111. When the second L-shaped plate 3116 moves downward, it will cause the sleeve 3112 to move, so that the extrusion rod 3114 in the sleeve 3112 can extrude the surface of the metal. By setting multiple extrusion rods 3114, it is possible to clamp and fix the metal parts with uneven surfaces, so as to avoid falling off during the bending process of the metal parts with uneven surfaces and improve the processing effect of the device.
[0034] During the bending process of the metal part, in order to facilitate the adjustment of the clamping distance between the two rectangular columns 318 according to the length of the metal part, the operator turns on the forward and reverse motor 313 to cause the output shaft 314 to rotate. During the rotation of the output shaft 314, the gear 315 is driven to rotate. During the rotation of the gear 315, it meshes with the rack 316 and moves the rectangular column 318 through the connecting block 317. This causes the displacement block 319 at the bottom of the rectangular column 318 to move laterally along the outer wall of the crossbar 3110, thereby facilitating the adjustment of the distance between the two rectangular columns 318 and effectively clamping and fixing the metal part according to its length.
[0035] After the metal part is fixed, when it needs to be bent, the operator turns on the cylinder 325, causing the output end of the cylinder 325 to push the bending block 326 downward, so that the bending block 326 bends the surface of the metal part. When it is necessary to adjust the bending position of the metal part, the operator turns on the drive motor 322, causing the lead screw 323 to rotate. During the rotation of the lead screw 323, the sleeve block 324 will move laterally along the outer wall of the lead screw 323, thereby driving the bending block 326 to move, so as to facilitate the adjustment of the bending position of the metal part.
[0036] The above description is merely an illustrative embodiment of this utility model and is not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model. Furthermore, it should be noted that the components of this utility model are not limited to the overall application described above. Each technical feature described in the specification of this utility model can be used individually or in combination as needed. Therefore, this utility model naturally covers other combinations and specific applications related to this application.
