Technical Field

[0001] The utility model relates to the technical field of bender, in particular to a bender for copper jumper wires. Background Art

[0002] The background technology of the benders for copper jumpers involves many aspects, among which the main concern is how to achieve accurate and reliable bending while maintaining the performance of the copper wire. As a common conductive material, copper wire has the advantages of hard texture, corrosion resistance, high temperature resistance, high pressure resistance, light weight, good thermal conductivity, and high low-temperature strength. However, when the copper wire is bent, if there are problems such as oxidation or pollution on its surface, these adverse factors may cause the copper wire to wrinkle during the bending process, thereby affecting its use effect. Therefore, it is particularly important to design a bender that can cope with these problems. In the design of the bender, the physical properties of the copper wire, such as strength, flexibility, resistance to thermal deformation and impact resistance, need to be considered. The bender needs to be able to accurately control the angle and shape of the bend to ensure that the copper jumper can maintain its original electrical and mechanical properties after bending. At the same time, the bender also needs to have sufficient durability and stability to cope with long-term and high-intensity use.

[0003] In the prior art, when bending a copper wire, since the tool itself is relatively hard, it is very likely that the copper wire will be wrinkled during the bending process; therefore, it does not meet the existing needs. In this regard, we propose a bender for copper jumper wires. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment 1: This embodiment is intended to promote the solution of the problem in the prior art that when bending the copper wire 360, since the tool itself is relatively hard, it is very likely that the copper wire 360 ​​will be wrinkled during the bending process. Figure 1-Figure 5 A bender for copper jumper wires includes a workbench 110, a mounting column 130 is fixedly installed on one side of the workbench 110, an insertion port 140 is opened in the middle of the mounting column 130, a processing component 370 is installed in the middle of the insertion port 140, and a bending column 120 is fixedly installed on the other side of the workbench 110, and a plurality of bending columns 120 are fixedly installed.

[0024] The bending column 120 includes a fixed column 150 fixedly installed in the middle of the workbench 110, a support rod 190 is hinged on the side of the fixed column 150, a connecting plate 200 is connected to the side of the support rod 190, the connecting plate 200 is hinged to the fixed column 150, a clamping plate 160 is installed on the side of the support rod 190, one end of the clamping plate 160 is inserted in the limiting groove 170, a limiting spring 180 is installed in the limiting groove 170, the other end of the clamping plate 160 is inserted in the clamping groove 210, one end of the limiting spring 180 is fixedly connected to the clamping plate 160, and the other end of the limiting spring 180 is fixedly connected to the inner wall of the limiting groove 170.

[0025] When the copper wire 360 ​​needs to be bent, the staff first inserts the copper wire 360 ​​into the mounting column 130 through the insertion port 140. Then, when the copper wire 360 ​​passes through the mounting column 130, through the setting of the processing component 370, when the copper wire 360 ​​moves, the wheels 340 on both sides of the clamping rod 290 will smooth the copper wire 360. Then the staff bends the copper wire 360 ​​through the bending column 120. During the bending process, since the copper wire 360 ​​is a hollow tube, if the bending column 120 is too hard, the copper wire 360 ​​will be squeezed and flattened. When the copper wire 360 ​​is bent, the bending degree of the copper wire 360 ​​will be different due to different forces.

[0026] During the bending process, when the staff applies force, the card plate 160 will squeeze the limit spring 180, and then expand and contract in the limit groove 170. Through the hinge connection between the connecting plate 200 and the fixed column 150, the card plate 160 will shrink in the card groove 210. Since the material of the card plate 160 is set to rubber material, the copper wire 360 ​​will not be damaged during the bending process of the copper wire 360, which can improve the utilization rate of the copper wire 360.

[0027] In the present embodiment: by setting the bending column 120, when the copper wire 360 ​​is bent, since the bending column 120 can be extended and retracted when subjected to force, when the copper wire 360 ​​is bent, the occurrence of wrinkles on the copper wire 360 ​​during the bending process is avoided as much as possible, thereby improving the utilization rate of the copper wire 360, and solving the problem mentioned in the above background technology that when bending the copper wire 360, the tool itself is relatively hard, so wrinkles are likely to appear on the copper wire 360 ​​during the bending process, thereby greatly improving the qualified rate and utilization rate of the copper wire 360 ​​during the bending process.

[0028] Embodiment 2: This embodiment is intended to promote the solution of the problem that, in the prior art, if the copper wire 360 ​​is not straightened before being bent, the copper wire 360 ​​is likely to be flattened or broken when being bent. This embodiment is an improvement made on the basis of Embodiment 1. For details, please refer to Figure 1-Figure 5 The processing assembly 370 includes a snap-fit ​​groove 350 connected to the side of the insertion port 140, and a fixing frame 220 is installed on both sides of the snap-fit ​​groove 350. A fixing block 240 is fixedly connected to the middle of the fixing frame 220, and a connecting rod 230 is fixedly installed in the middle of the fixing block 240. The connecting rod 230 is inserted in the middle of the fixing frame 220.

[0029] The end of the connecting rod 230 is hinged with a mounting block 250 through a rotating shaft 260. The mounting block 250 is fixedly mounted on the side of the rotating rod 270. A clamping rod 290 is inserted into the side of the rotating rod 270. The end of the clamping rod 290 is fixedly connected to a limiting plate 280. A partition 310 is fixedly mounted at the bottom of the clamping rod 290. A connecting box 320 is installed at the bottom of the partition 310.

[0030] An extrusion spring 300 is sleeved on the side of the clamping rod 290, one end of the extrusion spring 300 is fixedly connected to the rotating rod 270, and the other end of the extrusion spring 300 is fixedly connected to the partition 310. A mounting frame 330 is fixedly installed on the side of the connecting box 320, a rotating wheel 340 is rotatably installed in the middle of the mounting frame 330, a copper wire 360 ​​is inserted in the middle of the locking groove 350, and the rotating wheel 340 is intermittently in contact with the copper wire 360.

[0031] In the present embodiment, if the copper wire 360 ​​is not straightened before being bent, the copper wire 360 ​​is likely to be broken or flattened during the bending process. When straightening the copper wire 360, the staff directly inserts the copper wire 360 ​​from the insertion port 140 into the engaging groove 350, and then through the setting of the processing component 370, during the movement of the copper wire 360, the copper wire 360 ​​is flattened by the rotation of the rotating wheels 340 on both sides, so as to avoid the copper wire 360 ​​from being broken or flattened during subsequent bending as much as possible, thereby greatly improving the utilization rate of the copper wire 360.
