Description

Technical Field

[0001] This utility model relates to the technical field of copper wire processing equipment, and in particular to a copper wire straightening device. Background Technology

[0002] Copper wire, as a linear conductor made of pure copper or high-purity copper alloy, has become a core material in fields such as power transmission, electronic manufacturing, new energy, and high-end equipment due to its excellent conductivity, ductility, and corrosion resistance. However, copper wire is prone to residual stress during processing such as drawing, annealing, and stranding, which can lead to bending, wavy deformation, or local torsion of the wire. This directly affects the welding quality of electronic components, the transmission efficiency of power cables, and the assembly accuracy of precision equipment. For example, bent copper wire may cause short circuit risks in integrated circuit packaging and can lead to local overheating in high-voltage cables. Therefore, straightening devices are needed to straighten copper wire to facilitate subsequent use.

[0003] However, most existing straightening equipment directly straightens copper wires by squeezing them with straightening rollers. This method is prone to incomplete straightening or re-bending after straightening, thus reducing the straightening effect. In addition, different straightening rollers need to be changed for copper wires of different diameters, which is cumbersome and affects the straightening effect. In view of this, this utility model is proposed. Utility Model Content

[0004] To overcome the technical defects of existing technologies, this utility model provides a copper wire straightening device, which features good straightening effect and convenient operation. The copper wire can be moved by the wire pulling assembly, allowing it to pass through the heating assembly and the straightening assembly. The heating assembly heats the copper wire, and the straightening assembly straightens it, thereby improving the stress release effect and thus the straightening effect. Furthermore, the straightening roller in the straightening assembly has straightening grooves of different diameters, which can be flexibly adjusted according to the diameter of the copper wire, thus straightening copper wires of different diameters and improving the versatility of this structure.

[0005] The technical solution adopted by this utility model includes a workbench, a heating component, a wire pulling component, and a straightening component. The heating component, the wire pulling component, and the straightening component are all installed on the upper end of the workbench, and the straightening component is located between the heating component and the wire pulling component. In use, the structure is first placed at the location of use, and then one end of the copper wire to be straightened is passed through the heating component and the straightening component and snapped onto the wire pulling component. The wire pulling component can pull the copper wire to move, the heating component can heat the copper wire to release the internal stress of the copper wire, and the straightening component can straighten the copper wire. At the same time, the straightening component can be adjusted according to the diameter of the copper wire, improving the versatility and flexibility of this structure.

[0006] To straighten copper wires of different diameters, this invention improves upon the following: the straightening assembly includes a moving box, an adjusting threaded rod, a stepper motor, a slider, a mounting bracket, a bidirectional threaded rod, a self-locking motor, a lifting block, a rotating bearing, a rotating shaft, and a straightening roller. The moving box is fixedly installed at the upper center of the worktable. The adjusting threaded rod is rotatably engaged inside the moving box. The stepper motor is fixedly installed at one end of the moving box, and its output end is fixedly connected to one end of the adjusting threaded rod. The slider is slidably engaged inside the moving box and threadedly sleeved on the adjusting threaded rod. The mounting bracket is fixedly installed on both sides of the upper end of the slider. The frame is U-shaped. The bidirectional threaded rod is rotatably engaged on the mounting frame. The self-locking motor is fixedly mounted on the upper end of the mounting frame, and the output end of the self-locking motor is fixedly connected to the upper end of the bidirectional threaded rod. The mounting frame has a lifting groove. The lifting block is slidably engaged on the lifting groove and threadedly sleeved on the bidirectional threaded rod. The rotating bearing is embedded in the middle of one side of the lifting block, and the outer side of the rotating bearing is fixedly connected to the lifting block. The two ends of the rotating shaft are fixedly connected to the inner side of the rotating bearing. The straightening roller is fixedly mounted on the rotating shaft, and the outer side of the straightening roller has an array of straightening grooves with different diameters.

[0007] In order to place this structure at the place of use, the present invention is improved by: a support frame is fixedly installed on both sides of the lower end of the workbench, and a soft pad is fixedly installed on the lower end of the support frame.

[0008] To enable heating of the copper wire before straightening, the present invention includes the following improvements: the heating component includes a mounting base, which is fixedly installed on one side of the upper end of the workbench and located on one side of the straightening component; the heating box is fixedly installed on the upper end of the mounting base, the heating box is made of heat-insulating material, and semi-circular electric heaters are fixedly installed on both sides inside the heating box; and a conveying groove is provided in the middle of the upper end of the mounting base, the conveying groove being located between the electric heaters.

[0009] In order to enable the copper wire to be pulled, the present invention includes the following improvements: the wire pulling assembly includes a vertical plate, which is fixedly installed on the other side of the upper end of the workbench, and a connecting shaft is rotatably engaged between the vertical plates. A conveyor wheel is fixedly installed on the connecting shaft, and an anti-slip pad is fixedly installed on the outer side of the conveyor wheel. The present invention also includes the following improvements: a control motor is fixedly installed on one side of the vertical plate, and the output end of the control motor is fixedly connected to one end of the connecting shaft.

[0010] The beneficial effects of this utility model are:

[0011] 1. The stepper motor can drive the adjusting screw rod to rotate, which in turn drives the slider to move in the moving box, allowing the straightening roller to be adjusted laterally. This allows the copper wire to pass through straightening grooves of different diameters, ensuring that copper wires of different diameters can be straightened. This not only facilitates user operation but also improves the versatility of the structure.

[0012] 2. The electric heater can heat the copper wire, thereby releasing the internal stress of the copper wire, making it easier to straighten and less prone to springback, thus improving the straightening effect of the copper wire. At the same time, the conveying groove can complete the guidance and conveying of the copper wire. Attached Figure Description
