Description

Technical Field

[0001] The utility model relates to the technical field of copper bar production equipment, in particular to a bending machine for copper bar production. Background Art

[0002] Copper bars play a role in transporting current and connecting electrical equipment in circuits and are widely used in electrical equipment, especially in distribution cabinets. Due to the particularity of the application occasions of copper bars, the copper bars need to be bent according to the on-site use space to meet the installation requirements. However, most of the existing bending devices cannot fix the copper bar plates in multiple directions well. The copper bar plates are prone to shift due to the large force during bending, resulting in poor bending effects of the copper bar plates. At the same time, the production volume of copper bar plates is large, and different bending angles are often required to meet different installation requirements. Content of the Utility Model

[0003] In view of this, the utility model provides a bending machine for copper bar production, which can fix the copper bar plates in multiple directions, making the bending effect of the copper bar plates better. At the same time, it can adapt to copper bar plates of different sizes, and through the stamping of the pressing blocks one and two with different arc surface angles, the angles of the copper bar plates after being bent are different.

[0004] The technical solution is: a bending machine for copper bar production, including a chassis, a first motor, a lead screw, a clamping component and a bending component. The first motor is arranged on the upper part of the chassis. The lead screw is rotatably connected to the chassis, and the lead screw is fixedly connected to the output shaft of the first motor. The clamping component is arranged on the chassis, and the bending component is arranged on the chassis.

[0005] Further, the clamping component includes a sliding plate, a second motor, a first threaded rod, a guide rod, sliders, clamping plates, a pressing frame and springs. The sliding plate is slidably connected to the chassis. The sliding plate is threadedly connected to the lead screw. A second motor is arranged on one side of the sliding plate. The first threaded rod is rotatably connected to the sliding plate, and the first threaded rod is fixedly connected to the output shaft of the second motor. Two threads are arranged on the first threaded rod, and the two threads on the first threaded rod have opposite helix directions. The guide rod is arranged on the sliding plate. Two sliders are slidably connected to the sliding plate. The two sliders are symmetrically arranged. The two sliders are both threadedly connected to the first threaded rod. The two sliders both pass through the guide rod. Clamping plates are arranged on the sides of the two sliders close to each other. The pressing frame is slidably connected to the side of the chassis far from the first motor. An inclined surface is arranged on the upper part of the pressing frame. Four springs are connected between the pressing frame and the chassis.

[0006] Furthermore, the bending component includes a bottom plate, a third motor, a second threaded rod, a limiting rod, a moving block, a first pressing block, and a second pressing block. A bottom plate is provided on one side of the chassis away from the first motor. A third motor is provided on the bottom plate. A second threaded rod is rotatably connected to the bottom plate. The second threaded rod is fixedly connected to the output shaft of the third motor. There are two threads on the second threaded rod, and the two threads on the second threaded rod have opposite helix directions. A limiting rod is provided on the bottom plate. Two moving blocks are slidably connected to the bottom plate. The two moving blocks are symmetrically arranged. Both moving blocks are threadedly connected to the second threaded rod. A first pressing block is clamped on one of the moving blocks. One side of the first pressing block is a convex arc surface. A second pressing block is clamped on the other moving block. One side of the second pressing block is a concave arc surface. The convex arc surface of the first pressing block and the concave arc surface of the second pressing block cooperate with each other.

This can fix the copper busbar plate in multiple directions, making the copper busbar plate more stable during bending, thus making the bending effect of the copper busbar plate better. At the same time, it can also adapt to copper busbar plates of different sizes, and through the stamping of the first pressing block and the second pressing block with different arc surface angles, the angles of the copper busbar plate after bending are different, so that the bending efficiency of the copper busbar plate is higher.

Detailed Embodiment

[0012] The following further describes the present utility model in conjunction with the drawings and embodiments.

[0013] Embodiment 1: A bending machine for copper busbar production, as Figures 1 - 3As shown in the figure, it includes a chassis, a first motor, a lead screw, a clamping component, and a bending component. The first motor is welded to the upper part of the chassis. The lead screw is rotatably connected to the chassis and fixedly connected to the output shaft of the first motor. The clamping component is arranged on the chassis, and the bending component is arranged on the chassis.

[0014] Further, the clamping component includes a sliding plate, a second motor, a first threaded rod, a guide rod, a slider, a clamping plate, a pressing frame, and a spring. The sliding plate is slidably connected to the chassis. The sliding plate is threadedly connected to the lead screw. A second motor is provided on one side of the sliding plate. The first threaded rod is rotatably connected to the sliding plate and fixedly connected to the output shaft of the second motor. There are two threads on the first threaded rod, and the two threads on the first threaded rod have opposite helix directions. A guide rod is provided on the sliding plate. Two sliders are slidably connected to the sliding plate. The two sliders are symmetrically arranged. The two sliders are both threadedly connected to the first threaded rod. The two sliders both pass through the guide rod. Clamping plates are provided on the sides of the two sliders close to each other. A pressing frame is slidably connected to the side of the chassis away from the first motor. An inclined surface is provided on the upper part of the pressing frame. Four springs are connected between the pressing frame and the chassis through hooks.

[0015] Further, the bending component includes a bottom plate, a third motor, a second threaded rod, a limiting rod, a moving block, a first pressing block, and a second pressing block. The bottom plate is provided on the side of the chassis away from the first motor. The third motor is welded to the bottom plate. The second threaded rod is rotatably connected to the bottom plate and fixedly connected to the output shaft of the third motor. There are two threads on the second threaded rod, and the two threads on the second threaded rod have opposite helix directions. The limiting rod is connected to the bottom plate by bolts. Two moving blocks are slidably connected to the bottom plate. The two moving blocks are symmetrically arranged. The two moving blocks are both threadedly connected to the second threaded rod. A first pressing block is clamped on one of the moving blocks. One side of the first pressing block is a convex arc surface. A second pressing block is clamped on the other moving block. One side of the second pressing block is a concave arc surface. The convex arc surface of the first pressing block cooperates with the concave arc surface of the second pressing block.

[0016] First, manually place the copper busbar plate to be processed on the sliding plate, and then manually start Motor 2, Motor 1, and Motor 3. The output shaft of Motor 2 drives the first threaded rod to rotate. The rotation of the first threaded rod drives two sliders and two clamping plates to move towards each other. The two clamping plates will clamp the copper busbar plate. The output shaft of Motor 1 drives the lead screw to rotate. The rotation of the lead screw drives the sliding plate, Motor 2, the first threaded rod, two sliders, and two clamping plates to move towards the pressing frame. The copper busbar plate will contact the bottom plate and the inclined surface of the pressing frame. The copper busbar plate will lift the inclined surface of the pressing frame and extend between the first pressing block and the second pressing block. The copper busbar plate drives the pressing frame to move upward, and the four springs are stretched, causing the pressing frame to press the copper busbar plate. The output shaft of Motor 3 drives the second threaded rod to rotate. The rotation of the second threaded rod drives two moving blocks to move towards each other. The two moving blocks drive the first pressing block and the second pressing block to move towards each other. The convex arc surface of the first pressing block and the concave arc surface of the second pressing block will cooperate with each other to bend the copper busbar plate. At the same time, multiple first pressing blocks and second pressing blocks with different arc surface angles are equipped. When disassembling, just turn the bolts on the first pressing block and the second pressing block. After the copper busbar plate is bent, the output shaft of Motor 3 drives the second threaded rod to rotate in the reverse direction. The reverse rotation of the second threaded rod drives two moving blocks to move away from each other. The two moving blocks drive the first pressing block and the second pressing block to move away from each other. The output shaft of Motor 2 drives the first threaded rod to rotate in the reverse direction. The reverse rotation of the first threaded rod drives two sliders and two clamping plates to move away from each other. The two clamping plates no longer clamp the copper busbar plate. Then, manually remove the copper busbar plate. The four springs will return to their original positions and drive the pressing frame to move downward. The output shaft of Motor 1 drives the lead screw to rotate in the reverse direction. The reverse rotation of the lead screw drives the sliding plate, Motor 2, the first threaded rod, two sliders, and two clamping plates to move away from the pressing frame. Then, manually place the copper busbar plate to be processed on the sliding plate again. By repeating this process, the copper busbar plate can be fixed in multiple directions, making the copper busbar plate more stable during bending, thus making the bending effect of the copper busbar plate better. At the same time, it can also adapt to copper busbar plates of different sizes, and through the stamping of the first pressing block and the second pressing block with different arc surface angles, the angles of the copper busbar plate after bending are different, so that the bending efficiency of the copper busbar plate is higher.

[0017] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
