Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of copper material manufacturing and processing, in particular to a flat copper wire straightening device. BACKGROUND

[0002] Flat copper wire has the characteristics of high electrical conductivity, large current carrying capacity and high space utilization rate, and is widely used in the fields of new energy automobile motor winding, transformer coil, electric reactor and other power equipment. In the production and processing of flat copper wire, the wire body is prone to bending due to the influence of rolling, winding, transportation and other links. If it is directly used for subsequent winding processing, it will lead to uneven interlayer gap of winding and decline of insulation performance, so it must be straightened to ensure that the straightness and cross section flatness meet the processing requirements.

[0003] At present, the mainstream flat copper wire straightening equipment in the industry mainly adopts a multi-roller straightening structure, which specifically includes: a feeding roller group for conveying the wire body, an upper and lower staggered straightening wheel group for correcting longitudinal bending, and a left and right symmetric side wheel group for correcting transverse side bending. Although such equipment can achieve basic shape correction, it still has the following shortcomings: When the flat copper wire is straightened, it is extruded and rubbed by the rollers, and elastic internal stress is generated inside. If it is not eliminated in time, the wire body will appear secondary rebound due to internal stress release in the subsequent storage or processing process, resulting in a decrease in straightness. At the same time, in order to improve the straightening effect, some equipment increases the extrusion force of the rollers on the flat copper wire, which further aggravates the accumulation of internal stress.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0019] Embodiment 1: Please refer to Figure 1 and 6 ~ Figure 8 In the embodiments of the present application, a flat copper wire straightening device comprises a workbench 1, and leg 2 is fixedly installed on the bottom surface of the workbench 1 near the corner. The feeding mechanism 3 is fixedly installed on the top surface of the workbench 1 near the feeding end. The longitudinal straightening mechanism 4 is fixedly installed on the top surface of the workbench 1 and located on the side away from the feeding end of the workbench 1 of the feeding mechanism 3. The transverse straightening mechanism 5 is fixedly installed on the top surface of the workbench 1 and is located on the side away from the longitudinal straightening mechanism 4 of the feeding mechanism 3. The stress relief mechanism 6 is fixedly installed on the top surface of the workbench 1 and is located on the side away from the longitudinal straightening mechanism 4 of the transverse straightening mechanism 5, and the stress relief mechanism 6 comprises: The box body 37 is fixedly installed on the top surface of the workbench 1, a heat insulation plate 54 is fixedly installed at the middle position of the box body 37, an inlet 38 is arranged at one end of the box body 37 close to the transverse straightening mechanism 5, and an outlet 39 aligned with the inlet 38 is arranged at the other end of the box body 37, a through slot 52 aligned with the outlet 39 is arranged on the side surface of the heat insulation plate 54, an oil cooler 40 and a control module 55 are fixedly installed on the top surface of the box body 37, and an infrared temperature detector 53 electrically connected with the control module 55 is installed on the side surface of the heat insulation plate 54 close to the inlet 38; a first stress relief mechanism is arranged between the heat insulation plate 54 and the inlet 38 in the box body 37, a second stress relief mechanism 58 is arranged between the outlet 39 and the heat insulation plate 54, and a cooling oil circulation loop is formed between the first stress relief mechanism, the second stress relief mechanism 58 and the oil cooler 40.

[0020] The flat copper wire sequentially passes through the feeding mechanism 3, the longitudinal straightening mechanism 4, the transverse straightening mechanism 5 and the stress relief mechanism 6 to complete the whole process treatment. In the stress relief mechanism 6, the first stress relief mechanism heats the wire body through the eddy current effect of the coil 51 to release internal stress, the second stress relief mechanism 58 further stabilizes the wire body shape through the mechanical pressure retention of the elastic polyurethane roller 62, and the oil cooler 40 and the cooling oil circulation loop realize cooling of the wire body after heating and heat dissipation of the coil 51.

[0021] Therefore, through the arrangement of the feeding mechanism 3, the longitudinal straightening mechanism 4, the transverse straightening mechanism 5 and the stress relief mechanism 6, the integrated treatment of the flat copper wire guiding, straightening and stress relief is realized, the problem that the existing equipment only straightens but does not relieve stress is solved, the secondary rebound of the wire body is effectively avoided, and the stability of the straightness of the copper wire is significantly improved.

[0022] The oil cooler 40 is selected from mature industrial-grade cooling equipment in the industry, for example, a commonly used "air-cooled oil cooler" or "water-cooled oil cooler" on the market, and the working principle is based on "compressor refrigeration + heat exchanger heat exchange". The cooling oil temperature is collected in real time through the built-in temperature sensor, and the refrigeration power is adjusted through the controller to stabilize the cooling oil temperature in the set interval. This technology has been widely used in the fields of mechanical processing and electronic equipment heat dissipation, and is the prior art. In the stress relief mechanism 6 of the present application, the oil cooler 40 provides temperature-controllable cooling medium for the cooling oil circulation loop, and the specific structure is not improved.

[0023] Example 2: Please refer to Figure 8 andFigure 9 On the basis of Embodiment 1, the first stress relief mechanism comprises a mounting cylinder 50 fixedly mounted on the inner end face of the box body 37 close to the inlet 38, the mounting cylinder 50 is aligned with the inlet 38, a coil 51 is coaxially fixedly mounted in the mounting cylinder 50, and both ends of the coil 51 are sequentially and penetratingly fixedly mounted in the mounting cylinder 50 and the box body 37 to be electrically connected between the upper part of the box body 37 and the control module 55; The coil 51 is a hollow structure, and a plastic pipe joint is fixedly connected between one of the pipe joints close to both ends of the coil 51 and the oil return port of the oil cooler 40.

[0024] The control module 55 inputs alternating current into the coil 51 of the hollow structure, the coil 51 generates an alternating magnetic field, and the flat copper wire passing through the coil 51 self-heats due to the eddy current effect, thereby realizing internal stress release. The infrared temperature detector 53 detects the surface temperature of the wire body in real time and feeds back the data to the control module 55, the control module 55 adjusts the size of the alternating current to stabilize the temperature of the wire body in a suitable temperature range, for example, 250-300℃ (the best stress relief temperature range of red copper). Meanwhile, the cooling oil output by the oil cooler 40 flows into the inside of the coil 51 through the conduit one 56 after passing through the second stress relief mechanism 58, absorbs the heat generated by the coil 51 during operation, and then returns to the oil cooler 40 through the conduit three 59, thereby forming a cooling cycle.

[0025] In this embodiment, the first stress relief mechanism adopts the eddy current heating mode, realizes non-contact heating of the wire body, avoids surface scratches of the wire body caused by traditional contact heating, and realizes precise adjustment of the heating temperature through closed-loop control of the control module 55 and the infrared temperature detector 53, thereby avoiding the situation that the temperature is too high to cause the wire body to have coarse grains or the situation that the temperature is too low to cause incomplete stress relief. The hollow coil 51 establishes a cooling oil circuit, thereby simultaneously realizing wire body heating and coil heat dissipation and prolonging the service life of the coil 51.

The closed-loop control mode of "sensor + PLC + execution element" has been widely used in heating equipment, temperature regulation systems and other fields, which is the prior art.
