Abstract
Description
Technical Field
[0001] This utility model belongs to the field of copper processing equipment, and specifically relates to a bending device for copper processing. Background Technology
[0002] Copper tubing is a common type of copper material in daily life, serving as a primary material for conductive and heat dissipation components in electronic products. Copper tubing processing typically involves bending, a traditional method often performed manually, which is inefficient and labor-intensive. A utility model patent with authorization publication number CN212664594U discloses a bending device for copper processing. While this device improves bending efficiency, the copper tubing is fitted and clamped at both ends in insert sleeves, limiting its applicability to bending copper tubing of specific lengths and making it unsuitable for industrial processing of copper materials of varying diameters and lengths. Utility Model Content
[0003] In order to overcome the shortcomings of the existing technology, this utility model aims to provide a bending device for copper material processing. This device can perform fast and efficient bending operations on copper tubes and can adapt to the processing of copper tubes of different lengths and diameters. It is very convenient to use and can significantly improve the processing efficiency of copper tubes.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] A bending device for copper processing includes a worktable and a top block. The top block is movably mounted on the worktable and fixedly connected to the actuating part of a bending drive assembly. Two sets of clamping assemblies are symmetrically installed on the worktable on both sides of the top block. Each clamping assembly includes a first clamping wheel and a second clamping wheel. The first clamping wheel is vertically mounted on the worktable, and a swing plate is provided below the first clamping wheel. One end of the swing plate is horizontally mounted on the worktable about the axle of the first clamping wheel, and the other end of the swing plate is fixedly provided with an end plate. A screw is mounted on the end plate along the length of the swing plate. One end of the screw is equipped with a crank handle, and the other end is rotatably connected to a push plate, which is slidably mounted on the swing plate. The second clamping wheel is mounted on the push plate opposite to the first clamping wheel. The two sides of the copper tube are clamped and fixed between the two clamping wheels of the two sets of clamping assemblies.
[0006] Preferably, the top block has a semi-circular design.
[0007] Preferably, the bending drive assembly is an electric push rod, and the top block is fixed on the piston rod of the electric push rod.
[0008] Preferably, the swing plate has a groove along its length, and the bottom of the push plate is slidably formed in the groove.
[0009] Preferably, the second pressing wheel is mounted on the movable plate, and a slide rod is vertically fixed to the movable plate. The slide rod moves through the push plate and has a limiting block fixed at its extended end. A spring is sleeved on the slide rod, and the two ends of the spring abut against the push plate and the movable plate, respectively.
[0010] Preferably, the top block and the second pressing wheel are located on the same side of the copper tube; the first pressing wheel and the swing plate are rotatably mounted on the same rotating shaft, and a torsion spring connected to the swing plate is sleeved on the rotating shaft for driving the swing plate to rotate and then reset.
[0011] Preferably, a baffle is fixed on the worktable to limit the rotation of the swing plate during its reset.
[0012] The beneficial effects of this utility model are as follows:
[0013] 1. In the initial installation of the copper tube, the swing plate is in a vertical position to the copper tube. After the copper tube is placed horizontally on the two first clamping rollers on the left and right, the two cranks are rotated and turned to drive the corresponding screws and push plates to move, thereby bringing the two second clamping rollers closer together and clamping the copper tube. This clamps and fixes the left and right ends of the copper tube between the two sets of clamping rollers. When the electric push rod drives the top block to extend and bend, the middle of the copper tube will bend in a V-shape. When the copper tube is bent, the clamping rollers on both sides will keep the copper tube clamped, and the two swing plates will rotate and swing towards the center of the worktable, thereby ensuring the stability of the copper tube when bending.
[0014] 2. When the push plate of this application drives the second clamping wheel to approach the copper tube for clamping, it will compress the spring. Under the action of the spring force, the clamping of the copper tube by the two clamping wheels will be stable during the bending process of the copper tube.
[0015] 3. After the copper tube is removed after the bending operation is completed, the swing plate, the second pressure wheel and other structures will rotate horizontally to both sides around the pivot point to reset under the elastic force of the torsion spring until the swing plate abuts against the baffle, thus preparing for the next bending operation.

[0017] Figure 2 This is a schematic diagram of the clamping assembly of this utility model. Detailed Implementation
[0018] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of application of this utility model.
[0019] like Figure 1-2As shown, this utility model proposes a bending device for copper material processing, including a worktable 1 and a top block 22. The top block 22 is movably mounted on the worktable 1 and fixedly connected to the actuating part of the bending drive assembly. In this embodiment, the top block 22 has a semi-circular design, which avoids damage to the copper tube when bending it against the middle of the tube. The bending drive assembly adopts an electric push rod 21, and the top block 22 is fixed on the piston rod of the electric push rod 21.
[0020] Two sets of clamping assemblies are symmetrically installed on the worktables 1 on both sides of the top block 22. The clamping assemblies include a first clamping wheel 3 and a second clamping wheel 5. The first clamping wheel 3 is vertically installed on the worktable 1. A swing plate 4 is provided below the first clamping wheel 3. One end of the swing plate 4 is horizontally mounted on the worktable 1 with the wheel axle of the first clamping wheel 3 as the center. An end plate 41 is fixed to the other end of the swing plate 4. A screw 6 is installed on the end plate 41 along the length of the swing plate 4. A crank 61 is installed on one end of the screw 6, and the other end is rotatably connected to a push plate 7. The push plate 7 is slidably mounted on the swing plate 4. The top block 22 and the second clamping wheel 5 are located on the same side of the copper tube. In a specific implementation, a groove 42 is opened on the swing plate 4 along its length. The bottom of the push plate 7 is slidably opened in the groove 42. The push plate 7 can improve its stability during movement by cooperating with the groove 42.
[0021] In this application, during the initial installation of the copper tube, the swing plate 4 is in a vertical position relative to the copper tube. After the copper tube is placed horizontally on the two first clamping rollers on the left and right, the two cranks 61 are rotated and turned respectively, which drives the corresponding screws 6 and push plates 7 to move, thereby causing the two second clamping rollers 5 to approach and clamp the copper tube, thus clamping and fixing the left and right ends of the copper tube between the two sets of clamping rollers. When the electric push rod 21 drives the top block 22 to extend and bend, the middle part of the copper tube will be bent in a V-shape. When the copper tube is bent, the clamping rollers on both sides will keep the copper tube clamped, and the two swing plates 4 will rotate and swing towards the middle of the worktable 1, thereby ensuring the stability of the copper tube when bending.
[0022] Furthermore, the second clamping wheel 5 is mounted on the movable plate 51, and a slide rod 72 is vertically fixed to the movable plate 51. The slide rod 72 movably passes through the push plate 7 and has a limiting block 71 fixed at its extended end. A spring 73 is sleeved on the slide rod 72, and both ends of the spring 73 abut against the push plate 7 and the movable plate 51, respectively. The slide rod 72 limits the movement of the movable plate 51, maintaining the stability of the movement of the second clamping wheel 5. The two sides of the copper tube are clamped and fixed between the two clamping wheels of the two sets of clamping assemblies.
[0023] When the push plate 7 of this application drives the second clamping roller 5 to approach the copper tube for clamping, it will compress the spring 73. Under the elastic force of the spring 73, the clamping of the copper tube by the two clamping rollers will be stable during the bending process of the copper tube.
[0024] Furthermore, the first clamping wheel 3 and the swing plate 4 are rotatably mounted on the same rotating shaft 31. A torsion spring connected to the swing plate 4 is sleeved on the rotating shaft 31 to drive the swing plate 4 to rotate outward and reset. A baffle 11 is fixed on the worktable 1 to limit the rotation of the swing plate 4 during reset.
[0025] After the copper tube is removed during the bending operation, the swing plate 4, the second pressure wheel 5 and other structures will rotate horizontally to both sides around the pivot 31 to reset under the elastic force of the torsion spring until the swing plate 4 abuts against the baffle 11, preparing for the next bending operation.
[0026] When using this invention, the copper tube is placed horizontally between the two first clamping rollers 3 on the left and right. The crank handle 61 is then rotated to rotate the screw 6, causing the two second clamping rollers 5 to press against the copper tube, compressing the spring 73. Then, the electric push rod 21 drives the top block 22 to extend for bending. The middle of the copper tube will deform into a V-shape. Under the elastic force of the spring 73, the clamping rollers on both sides will hold the copper tube in place, while the two swing plates 4 will rotate and swing towards the center of the worktable 1. During this process, the torsion spring deforms. After the bending operation is completed, the crank handle 61 is rotated in the opposite direction to release the copper tube clamping. After removing the copper tube, the torsion spring will cause the swing plates 4, the second clamping rollers 5, and other structures to rotate and reset, preparing for the next bending operation.
