Description

Technical Field

[0001] The present invention relates to the technical field of wire and cable hook shaping, and specifically relates to a wire and cable hook forming machine. Background Art

[0002] Existing wire and cable hooks need to be bent by a bending machine before they can be formed. The bending machines include manual and automatic types. However, whether manual or automatic, the bending principle is basically the same, that is, the lever principle is used to bend the raw materials. However, the existing equipment does not have an adjustment function and cannot adjust the placement gap according to the actual thickness of the raw materials, resulting in poor adaptability of the bending machine.

[0003] Chinese Patent CN220532838U discloses a cable hook bending machine, including a base. The top of the base is in contact connection with a setting column. A bending mechanism is provided on the top of the setting column, and a connection mechanism is provided between the setting column and the base; the bending mechanism includes a fixed column fixedly connected to the top of the setting column. An outer wall of the fixed column is fixedly provided with a bearing. An outer wall of the bearing is fixedly provided with a turntable. An inner wall of a chute opened on one side of the top of the turntable is rotatably connected with a screw rod. An outer wall of the screw rod is threadedly connected with a slider. The top of the slider is fixedly connected with a mounting plate. One side of the top of the mounting plate is fixedly provided with an arc-shaped baffle. The other side of the top of the mounting plate is rotatably connected with a movable pulley. An outer wall of the turntable is fixedly provided with a push handle.

[0004] The above solution enables the size of the gap for placing raw materials to be adjusted arbitrarily. However, when bending the raw materials, it can only adapt to simple-shaped bends, so it cannot be applied to the processing of wire and cable hooks with multi-directional bends. At the same time, the above solution is a manual operation, and the bent hooks need to be manually taken out and loaded, resulting in a large working intensity. At the same time, some existing wire and cable hooks are also provided with rubber pads on the outside. The rubber pads will hinder the bending machine in the existing bending process, thereby causing the bending to be impossible. Summary of the Invention

[0005] In view of the above problems, a wire and cable hook forming machine is provided. By opening a bending groove on the processing panel and arranging a shaping block on the inner side of the semi-surround formed by the bending groove, when the hook is shaped for the first time, the lifting frame rises in the vertical direction. Driven by the lifting frame, the two first bending rollers rise synchronously with the lifting frame, and each first bending roller is tightly attached to the side wall of the hook under the elastic force of the spring. In the second bending process, when the second bending roller rotates with the pressing rod, an arc-shaped sweeping area is formed. The second bending roller bends the hook twice by rotating. In this way, the forming machine of the present invention can not only bend the hook with a rubber pad, but also adapt to the shaping requirements of hooks with different diameters.

[0006] To solve the problems of the existing technology, the present invention provides a wire hook forming machine, which includes a processing panel. Horizontally and fixedly arranged on the processing panel is a receiving rail for receiving the hook before processing. A bending groove is formed on the processing panel. The bending groove is of a "U" - shaped structure. A first bending unit is also arranged on the processing panel. The first bending unit includes a shaping block arranged on the processing panel. The lower part of the shaping block is of an arc - shaped structure. The center of the circle of the lower part of the bending groove is concentric with the center of the arc - shaped structure of the shaping block. The shaping block is located inside the semi - enclosed area formed by the bending groove. Two first bending rollers are arranged in the bending groove. The two first bending rollers are symmetrically arranged with respect to the shaping block. A lifting block is arranged at the end of each first bending roller. A lifting frame that moves vertically is arranged on one side of the lifting block. There is a gap between the lifting block and the lifting frame. A spring with both ends fixedly connected to the lifting block and the lifting frame respectively is arranged in the gap. When the lifting frame moves up and down vertically, the two first bending rollers move synchronously along the extending direction of the bending groove on both sides of the shaping block in the bending groove.

[0007] Preferably, when the lifting frame moves vertically, it successively has the highest position, the middle position, and the lowest position from top to bottom in the vertical direction. When the lifting frame is at the highest position, the hook is completed with the second bending, and neither of the two first bending rollers contacts the hook. When the lifting frame is at the middle position, the hook is completed with the first bending and is in a "U" - shaped structure. At the same time, the two first bending rollers located on both sides of the shaping block respectively contact the two vertical structures of the hook. When the lifting frame is at the lowest position, the horizontal end surfaces formed by the upper parts of the circumferences of the two first bending rollers are coplanar with the upper end surface of the receiving roller. The hook located on the receiving roller is in a straight line shape, and the bottom of the shaping block does not contact the hook.

[0008] Preferably, the straight - line distance in the vertical direction between the upper end surface of the receiving rail and the lower part of the shaping block is 2 cm.

[0009] Preferably, a second bending unit is also arranged on the processing panel. The second bending unit includes two support blocks. The two support blocks are respectively located on both sides of the shaping block. An upper - pressing unit for performing the second bending on the hook after the first shaping is arranged on the upper part of the support block. When the upper - pressing unit presses the hook, the upper part of the support block provides support for the lower part of the bent hook.

[0010] Preferably, the upper - pressing unit includes a first rotary driver horizontally arranged on the processing panel. A pressing rod is arranged at the end of the first rotary driver. A second bending roller is arranged at the end of the pressing rod far from the first rotary driver. When the second bending roller rotates with the pressing rod, an arc - shaped sweeping area is formed. The minimum straight - line distance between the inner ring of the arc - shaped sweeping area and the upper part of the support block is 1 cm.

[0011] Preferably, a clamping unit is provided on the side wall of the forming block, and the clamping unit includes a clamping groove opened on the side wall of the forming block along the thickness direction of the processing panel, a clamping plate is provided in the clamping groove for movement along the extension direction of the clamping groove, and an electric push rod for pushing the clamping plate to move is provided at the end of the clamping plate, and before the hook is bent for the second time, the clamping plate and the support block jointly clamp the hook.

[0012] Preferably, the shaping block passes through the processing panel along the thickness direction of the processing panel, and a movable frame is provided on the side of the processing panel away from the receiving rail. The movable frame is fixedly connected to the shaping block, and a slide is provided at the lower part of the movable frame. The slide drives the shaping block to move along the direction of the processing panel through the movable frame.

[0013] Preferably, a bidirectional coil spring is provided at the connection between the electric push rod and the clamping plate, and the clamping plate is in a horizontal state when no thrust is applied in the vertical direction.

[0014] Preferably, a gear is provided between the two support blocks, meshing teeth are provided on the sides of the two support blocks close to each other, the gear meshes with the meshing teeth on the two support blocks respectively, and a second rotary driver for driving the gear to rotate is provided at the end of the gear.

[0015] Preferably, a third rotary driver is vertically arranged on the mobile frame, and an output end of the third rotary driver is vertically downward. A threaded rod is fixedly arranged on the output end of the third rotary driver, and the threaded rod passes through the lifting frame in a vertical direction and cooperates with the lifting frame thread. A guide rod is arranged in parallel on one side of the threaded rod, and the guide rod passes through the lifting frame and cooperates with the lifting frame in a sliding manner.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. By opening a bending groove on the processing panel and arranging a shaping block on the inner side of the semi-enclosed area formed by the bending groove, when the hook is shaped for the first time, the lifting frame rises in the vertical direction. Driven by the lifting frame, the two first bending rollers rise synchronously with the lifting frame, and each first bending roller is tightly attached to the side wall of the hook under the elastic force of the spring. The distance between the upper end face of the receiving rail and the lower part of the shaping block in the vertical direction is greater than 2 cm, so that hooks with rubber pads of different sizes can be put into the forming machine of the present invention for processing, and in the second bending process, the second bending roller forms an arc sweeping area when rotating with the lower pressure rod, and the minimum straight-line distance between the inner ring of the arc sweeping area and the upper part of the support block is 1 cm, so that the second bending roller can also bend hooks of different sizes. In this way, the forming machine of the present invention can not only bend hooks with rubber pads, but also shape hooks of different diameters.

[0018] 2. By setting the clamping plate, the clamping plate is pushed out by the electric push rod according to a preset program before the hook is bent for the second time. At the same time, the sliding table drives the shaping block to retract into the processing panel through the moving frame. During the retraction of the shaping block, the support block on the shaping block jointly clamps the hook. In this way, when the second bending roller bends the hook for the second time, the reaction force during the bending of the hook will not act on the rubber pad, avoiding damage to the rubber pad installed on the hook during bending.

[0019] 3. When the hook is bent for the second time, the sliding table drives the moving frame to drive the shaping block to slide out from the processing panel. At the same time, the electric push rod also drives the clamping plate to retract, so that the clamping plate and the support block no longer clamp the hook. Subsequently, the lifting frame drives the first bending roller to rise from the middle position to the highest position in the vertical direction. During this process, the first bending roller needs to pass through the clamping plate. Therefore, a bi-directional coil spring is set at the connection between the clamping plate and the electric push rod. When the first bending roller passes through the clamping plate, it can push the clamping plate to rotate. When the first bending roller passes through the clamping plate, the clamping plate returns to the horizontal state again under the action of the bi-directional coil spring. When the first bending roller moves to the highest position, the first bending roller no longer contacts the hook. At this time, the hook is hung on the support block. Subsequently, the second rotary driver is started, and the second rotary driver drives the gear to rotate. The gear drives the two support blocks to retract. In this way, the support block no longer supports the hook, and the hook drops under the action of gravity, thus realizing the automatic discharging of the molding machine.

Detailed implementation manners

[0033] To further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be described in further detail below with reference to the drawings and specific implementation manners.

[0034] Refer to Figures 1 - 4 and Figure 11:A wire hook forming machine, including a processing panel 1, on which a receiving rail 11 for receiving the hook 3 before processing is horizontally and fixedly arranged; a bending groove 12 is formed on the processing panel 1, and the bending groove 12 is of a "U" - shaped structure. A first bending unit 2 is also arranged on the processing panel 1. The first bending unit 2 includes a shaping block 21 arranged on the processing panel 1. The lower part of the shaping block 21 is of an arc structure. The center of the lower part of the bending groove 12 is concentric with the center of the arc structure of the shaping block 21. The shaping block 21 is located inside the semi - enclosure formed by the bending groove 12. Two first bending rollers 22 are arranged in the bending groove 12. The two first bending rollers 22 are symmetrically arranged with respect to the shaping block 21. An elevating block 24 is arranged at the end of each first bending roller 22. An elevating frame 23 that moves vertically is arranged on one side of the elevating block 24. There is a gap between the elevating block 24 and the elevating frame 23. A spring 25 whose two ends are respectively fixedly connected to the elevating block 24 and the elevating frame 23 is arranged in the gap. When the elevating frame 23 moves up and down vertically, the two first bending rollers 22 move synchronously along the extending direction of the bending groove 12 in the bending groove 12 on both sides of the shaping block 21.

[0035] When the existing hook 3 bending machine bends the hook 3, it can only bend the body of the hook 3, that is, the hook 3 is in a single - wire state. And some existing wire hooks 3 are also provided with rubber pads 31. If the rubber pad 31 is combined and installed with the hook 3 after the hook 3 is bent and formed, it will be difficult to install the rubber pad 31 because there are clamping interfaces on the rubber pad 31, and when the hook 3 and the rubber pad 31 are combined, the hook 3 needs to be inserted into the clamping interface of the rubber pad 31. And the easier assembly method is to pass the straight - state hook 3 through the clamping interface of the rubber pad 31 when the hook 3 is in a straight state. However, the existing bending machines cannot adapt to bending the hook 3 with a rubber pad 31.

[0036] In order to enable the forming machine to adapt to bending the hook 3 with a rubber pad 31, the forming machine is further optimized. The specific structure and working process are as follows:

[0037] A plurality of extension rods 26 are fixedly arranged at the end of the elevating block 24. A spring 25 is sleeved outside each extension rod 26. The extension rods 26 penetrate through the elevating frame 23 along the horizontal direction and are in sliding fit with the elevating frame 23.

[0038] This cable hook 3 needs to go through two bending processes to be finally formed. First, the first forming process will be introduced. The first forming process is undertaken by the first bending unit 2. A linear driver is provided at one end of the receiving roller. The linear driver can push the hook 3 sleeved with a rubber sleeve into the receiving rail 11. A limiting plate is provided at the other end of the receiving rail 11. When the end of the linearly shaped hook 3 contacts the limiting plate, it is limited. In this way, the positioning of the hook 3 is completed, ensuring that after the first bending process, the hook 3 is in a symmetrical "U" - shaped structure.

[0039] The moving path of the lifting frame 23 in the vertical direction has a lowest position and a highest position. When the hook 3 is just pushed onto the receiving rail 11 and positioned, the lifting frame 23 is at the lowest position. At this time, the upper parts of the two first bending rollers 22 contact the lower part of the hook 3. The horizontal end faces formed by the upper parts of the two first bending rollers 22 are coplanar with the upper end face of the receiving rail 11, and at this time, the lower part of the shaping block 21 does not contact the upper part of the hook 3. In this way, the forming machine can adapt to the processing of hooks 3 with various diameters, as long as the thickness of the hook 3 sleeved with the rubber pad 31 is less than the minimum distance between the shaping block 21 and the receiving rail 11 in the vertical direction. The preferred solution here is that the linear distance between the upper end face of the receiving rail 11 and the lower part of the shaping block 21 is 2 cm, so that it can adapt to various hooks 3 equipped with rubber pads 31. Subsequently, the first bending operation on the hook 3 starts. The lifting frame 23 rises in the vertical direction, and the two first bending rollers 22 rise synchronously under the drive of the lifting frame 23. Each first bending roller 22 is tightly attached to the side wall of the hook 3 under the elastic force of the spring 25. Only in this way can the bent hook 3 be better formed. It should be noted that the groove width of the bending groove 12 is larger than the diameter of the first bending roller 22, so that the distance between the first bending roller 22 and the shaping block 21 can be adjusted flexibly. At the same time, the width of the bending groove 12 should not be set too large because the elastic force of the spring 25 is limited. When the first bending roller 22 moves upward along the vertical structure of the bending groove 12, the bending force on the hook 3 is all provided by the spring 25 at this time. Although as the first bending roller 22 rises, the moment of the first bending roller 22 on the hook 3 becomes longer, making the hook 3 easier to deform. There is also an intermediate position between the highest position and the lowest position of the lifting frame 23. During the first bending process, the first bending roller 22 stops moving after rising to the intermediate position. In this way, the first bending of the hook 3 is completed. In this way, the forming machine of the present invention can not only bend the hook 3 with a rubber pad 31, but also adapt to the shaping requirements of hooks 3 with different diameters.

[0040] However, the elastic force of the spring 25 will attenuate after long-term use. Thus, the width of the bending groove 12 is restricted so that when the spring 25 attenuates, the first bending roller 22 can always move upward along the periphery of the bending roller and still has a shaping effect on the hook 3. The hook 3 processed in this way is not a standard "U" - shaped structure. There will be a certain inclination in the original vertical structure of the hook 3 under standard conditions, but the inclination angle is usually within 5 degrees, which does not affect the actual use. Of course, according to the usage requirements, a spring 25 with a larger elastic coefficient can also be selected during actual use, and the spring 25 can be replaced regularly to achieve stable correction of the shaping of the hook 3.

[0041] Refer to Figures 1 - 11 : When the lifting frame 23 moves in the vertical direction, it successively has the highest position, the middle position, and the lowest position from top to bottom in the vertical direction. When the lifting frame 23 is at the highest position, the hook 3 completes the secondary bending, and neither of the two first bending rollers 22 contacts the hook 3. When the lifting frame 23 is at the middle position, the hook 3 completes the first bending and forms a "U" - shaped structure. At the same time, the two first bending rollers 22 located on both sides of the shaping block 21 respectively contact the two vertical structures of the hook 3. When the lifting frame 23 is at the lowest position, the horizontal end surfaces formed by the upper parts of the circumferences of the two first bending rollers 22 are coplanar with the upper end surface of the receiving roller, and the hook 3 located on the receiving roller is in a straight line, and the bottom of the shaping roller does not contact the hook 3.

[0042] Refer to Figures 1 - 11 : The straight - line distance in the vertical direction between the upper end surface of the receiving rail 11 and the lower part of the shaping block 21 is 2 cm.

[0043] Refer to Figures 1 - 11 : A second bending unit 4 is also provided on the processing panel 1. The second bending unit 4 includes two support blocks 41. The two support blocks 41 are respectively located on both sides of the shaping block 21. An upper pressing unit 42 for performing secondary bending on the hook 3 after the first shaping is provided on the upper part of the support block 41. When the upper pressing unit 42 presses the hook 3, the upper part of the support block 41 provides support for the lower part of the bent hook 3.

[0044] After the hook 3 completes the first shaping, the hook 3 has not yet formed a hook - like structure, while after the secondary shaping, the hook 3 forms a hook - like structure, thus completing the shaping.

[0045] Refer to Figure 2 、 Figure 5 and Figure 6The pressing unit 42 includes a first rotary driver 423 horizontally arranged on the processing panel 1, a pressing rod 421 is arranged at the end of the first rotary driver 423, a second bending roller 422 is arranged on the end of the pressing rod 421 away from the first rotary driver 423, and the second bending roller 422 forms an arc sweeping area when rotating with the pressing rod 421, and the minimum straight-line distance between the inner ring of the arc sweeping area and the upper part of the support block 41 is 1 cm.

[0046] If the lower pressure rod 421 drives the second bending roller 422 to rotate one circle, the moving area formed by the second bending roller 422 is a ring structure. In this way, during the actual bending operation, the arc sweeping area formed by the lower pressure rod 421 driving the second bending roller 422 to rotate has an inner ring and an outer ring. The diameter of most hooks 3 is less than 1 cm, so the second bending unit 4 can perform secondary bending on hooks 3 of different diameters. During the secondary bending, the first rotary driver 423 drives the lower pressure rod 421 to rotate, and the lower pressure rod 421 drives the second bending roller 422 to rotate out of the processing panel 1 and contact the hook 3. Then the first rotary driver 423 continues to drive the lower pressure rod 421 to rotate, so that the second bending roller 422 begins to bend the hook 3, thereby realizing the second bending process. After the secondary bending is completed, the first rotary driver 423 drives the lower pressure rod 421 to rotate and reset.

[0047] Reference Figures 8 - 10 A clamping unit 43 is arranged on the side wall of the shaping block 21, and the clamping unit 43 includes a clamping groove 433 opened on the side wall of the shaping block 21 along the thickness direction of the processing panel 1, and a clamping plate 431 is arranged in the clamping groove 433 for movement along the extension direction of the clamping groove 433, and an electric push rod 432 for pushing the clamping plate 431 to move is arranged at the end of the clamping plate 431. Before the hook 3 is bent for the second time, the clamping plate 431 and the support block 41 jointly clamp the hook 3.

[0048] Reference Figure 3 and Figure 7 : The shaping block 21 penetrates the processing panel 1 along the thickness direction of the processing panel 1, and a moving frame 5 is arranged on the side of the processing panel 1 away from the receiving rail 11. The moving frame 5 is fixedly connected to the shaping block 21, and a slide 51 is arranged at the lower part of the moving frame 5. The slide 51 drives the shaping block 21 to move along the direction of the processing panel 1 through the moving frame 5.

[0049] Before the hook 3 undergoes the secondary bending, the electric push rod 432 pushes out the clamping plate 431 according to a preset program, causing the clamping plate 431 to contact the hook 3. Since a rubber pad 31 is installed on the hook 3, the pushing distance of the clamping plate 431 can be preset according to the straight-line distance from the side wall of the rubber pad 31 to the side wall of the hook 3 on the same side. At the same time, the sliding table 51 drives the shaping block 21 to retract into the processing panel 1 through the moving frame 5. During the retraction of the shaping block 21, the support block 41 on the shaping block 21 jointly clamps the hook 3. In this way, when the second bending roller 422 performs the secondary bending on the hook 3, the reaction force during the bending of the hook 3 will not act on the rubber pad 31, avoiding damage to the rubber pad 31 installed on the hook 3 during bending. When the moving frame 5 moves, the first bending roller 22 moves along the thickness direction of the processing panel 1 together with the moving frame 5.

[0050] Refer to Figures 1 - 11 : A bi-directional coil spring is provided at the connection between the electric push rod 432 and the clamping plate 431. When the clamping plate 431 is not subjected to a vertical thrust, it is in a horizontal state.

[0051] Refer to Figure 6 : A gear 44 is provided between the two support blocks 41. Meshing teeth are provided on the sides of the two support blocks 41 that are close to each other. The gear 44 meshes with the meshing teeth on the two support blocks 41 respectively. A second rotary driver 45 for driving the gear 44 to rotate is provided at the end of the gear 44.

[0052] When the secondary bending of the hook 3 is completed, blanking is required. Before blanking, the sliding table 51 drives the moving frame 5 to drive the shaping block 21 to slide out from the processing panel 1, and at the same time, the electric push rod 432 also drives the clamping plate 431 to retract, so that the clamping plate 431 and the support block 41 no longer clamp the hook 3. Subsequently, the lifting frame 23 drives the first bending roller 22 to rise from the middle position to the highest position along the vertical direction. During the process of the first bending roller 22 rising from the middle position to the highest position, the first bending roller 22 needs to pass through the clamping plate 431. In this way, a bi-directional coil spring is provided at the connection between the clamping plate 431 and the electric push rod 432. When the first bending roller 22 passes through the clamping plate 431, it can push the clamping plate 431 to rotate. When the first bending roller 22 passes through the clamping plate 431, the clamping plate 431 returns to the horizontal state again under the action of the bi-directional coil spring. When the first bending roller 22 moves to the highest position, the first bending roller 22 no longer contacts the hook 3. At this time, the hook 3 is hung on the support block 41. Subsequently, the second rotary driver 45 is started, and the second rotary driver 45 drives the gear 44 to rotate. The gear 44 drives the two support blocks 41 to retract. In this way, the support block 41 no longer supports the hook 3, and the hook 3 then drops under the action of gravity, thus realizing the automatic discharging of the molding machine.

[0053] Refer to Figure 3 andFigure 9 : A third rotation driver 54 is vertically arranged on the moving frame 5. The output end of the third rotation driver 54 is vertically downward. A threaded rod 52 is fixedly arranged on the output end of the third rotation driver 54. The threaded rod 52 penetrates through the lifting frame 23 in the vertical direction and is in threaded cooperation with the lifting frame 23. A guide rod 53 is arranged in parallel on one side of the threaded rod 52. The guide rod 53 penetrates through the lifting frame 23 and is in sliding cooperation with the lifting frame 23.

[0054] The third rotation driver 54 is preferably a servo motor. After the third rotation driver 54 is started, the third rotation driver 54 can drive the lifting frame 23 to lift through the threaded rod 52.

[0055] Working principle: There are two shaping processes in total for shaping the hook 3. In the first shaping process, the straight hook 3 is first pushed into the receiving rail 11 and limited by the receiving rail 11. Subsequently, the lifting frame 23 rises in the vertical direction. The two first bending rollers 22 rise synchronously under the drive of the lifting frame 23. Each first bending roller 22 is tightly attached to the side wall of the hook 3 under the elastic force of the spring 25. Only in this way can the bent hook 3 be better formed. It should be noted that the groove width of the bending groove 12 is larger than the diameter of the first bending roller 22, so that the distance between the first bending roller 22 and the shaping block 21 can be adjusted flexibly. At the same time, the width of the bending groove 12 should not be set too large, because the elastic force of the spring 25 is limited. When the first bending roller 22 moves upward along the vertical structure of the bending groove 12, the bending force on the hook 3 is all provided by the spring 25 at this time. Although as the first bending roller 22 rises, the moment of the first bending roller 22 on the hook 3 becomes longer, making the hook 3 easier to deform. There is also an intermediate position between the highest position and the lowest position of the lifting frame 23. During the first bending process, the first bending roller 22 stops moving after rising to the intermediate position. In this way, the first bending of the hook 3 is completed.

[0056] During the secondary bending, the first rotation driver 423 drives the pressing rod 421 to rotate. The pressing rod 421 drives the second bending roller 422 to rotate out from the processing panel 1 and contact the hook 3. Subsequently, the first rotation driver 423 continues to drive the pressing rod 421 to rotate. In this way, the second bending roller 422 begins to bend the hook 3, thus realizing the secondary bending process.
