[0018] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0020] like Figures 1-6 The rotor coil flat copper wire rolling processing equipment shown includes a base 1, an oil groove 102 is provided on the top of the base 1, an unwinding roller 101 is provided on the top of the base 1, a rolling mechanism 2 is provided on the top of the base 1 above the oil groove 102, and a winding mechanism 3 is provided on the top of the base 1 on the side of the rolling mechanism 2 away from the unwinding roller 101. The calendering mechanism 2 includes two mounting plates 201 that are fixedly connected to the base 1 and symmetrically distributed. At least three sets of calendering components are arranged on the inner side of the mounting plates 201 and arranged from left to right. Auxiliary components are provided on the surface of the calendering components.

[0021] The coil to be processed is wound on the surface of the unwinding roller 101. Before processing, its free end passes through the calendering mechanism 2 and is fixed on the surface of the winding mechanism 3. The winding mechanism 3 is then started to perform calendering operations on it.

[0022] Specifically, the oil tank 102 is filled with lubricating oil, which can be applied to the surface of the coil during the rolling process to improve the rolling effect and avoid excessive friction that could cause burrs on the surface of the coil.

[0023] like Figures 1-6 As shown, the calendering assembly includes two symmetrically distributed calendering rolls 206. Both ends of the two calendering rolls 206 penetrate the mounting plate 201 and are provided with limit blocks 203. The ends of the calendering rolls 206 are rotatably connected to the inner walls of the adjacent limit blocks 203. The lower limit block 203 is fixedly connected to the surface of the mounting plate 201, and the upper limit block 203 is slidably connected to the surface of the mounting plate 201.

[0024] The surface of the calender roll 206 is provided with calendering grooves 207, and the depth of the calendering grooves 207 decreases from left to right.

[0025] One of the mounting plates 201 has an adjusting screw 204 rotatably connected to its surface between two limiting blocks 203. The upper end of the adjusting screw 204 is threaded through the adjacent limiting block 203. The other mounting plate 201 has a guide rod 202 symmetrically distributed with the adjusting screw 204. The limiting block 203 near the guide rod 202 has a guide hole. The surface of the guide rod 202 is slidably connected to the inner wall of the adjacent guide hole.

[0026] The copper wire passes through the rolling groove 207 between the two rolling rollers 206. During the winding process, it is squeezed by the rolling groove 207 to achieve the effect of rolling. The opening depth of the rolling groove 207 decreases from left to right, which can gradually process the copper wire to the required specifications. The step-by-step reduction can reduce the resistance to the movement of the copper wire and reduce the cost of use. During winding, there is no need for a high-power motor 301 to provide excessive traction force. The high tensile force required for one-time forming is distributed into multiple small-scale processing stages, reducing the load on the equipment.

[0027] Furthermore, according to the processing specifications, the corresponding calendering roll 206 can be moved upward by rotating the adjusting screw 204. It should be noted that the adjustment should be carried out in order of increasing depth of the calendering groove 207 to ensure that the calendering roll 206 does not come into contact with the copper wire, thereby realizing calendering operations of various specifications and effectively expanding the applicability of the equipment.

[0028] like Figures 1-6 As shown, several sets of connecting plates 208 are arranged between the two mounting plates 201 and are staggered with the calendering rollers 206. Each set of connecting plates 208 consists of two plates, and a lubricating block 209 is fixedly connected to the opposite side of each set of connecting plates 208. The lower connecting plate 208 is fixedly connected to the opposite side of the two mounting plates 201. The two ends of the upper connecting plate 208 pass through the two mounting plates 201 respectively and are fixedly connected to a fixing rod 214. A connecting rod 205 is fixedly connected to the upper end of the fixing rod 214, and the other end of the connecting rod 205 is fixedly connected to the surface of the upper limiting block 203.

[0029] A connecting pipe 210 is fixedly connected to the bottom of the upper connecting plate 208. The lower end of the connecting pipe 210 passes through two lubrication blocks 209 and the lower connecting plate 208 in sequence and extends into the interior of the oil tank 102. The surface of the connecting pipe 210 is provided with evenly distributed through grooves 211. The interior of the connecting pipe 210 is filled with an adsorption column 213. The lower end of the adsorption column 213 passes through the connecting pipe 210 and is fixedly connected to an adsorption block 212. The lubrication block 209, the adsorption column 213 and the adsorption block 212 are all sponge material components.

[0030] The adsorption blocks 212 and adsorption columns 213 of the sponge material components can adsorb the lubricating oil inside the oil tank 102. The through groove 211 allows the lubricating oil to wet the lubricating blocks 209 through the adsorption columns 213, so that the copper wire passing between the two lubricating blocks 209 can be coated with lubricating oil, which facilitates lubrication and cooling during the rolling process. At the same time, when adjusting the upper rolling roller 206, the upper connecting plate 208 can be moved synchronously through the fixed rod 214 and the connecting rod 205, so that the two lubricating blocks 209 can be separated from each other, which facilitates the passage of copper wire. During the rolling process, the lubricating oil coated on the surface of the copper wire will remain inside the rolling tank 207 when it is squeezed and eventually drips into the oil tank 102 for reuse, avoiding the problem of lubricating oil dripping during the rolling process in traditional rolling equipment, which is not conducive to cleaning.

[0031] like Figures 1-6 As shown, the winding mechanism 3 also includes two fixed plates 305 respectively fixedly connected to one side of the two mounting plates 201. Support plates 307 are fixedly connected to the opposite sides of the two fixed plates 305. An adjusting roller 312 is provided at the bottom of the support plate 307, and an adjusting rod 311 is provided at the top of the support plate 307. The lower end of the adjusting rod 311 passes through the support plate 307 and is rotatably connected to the end of the adjusting roller 312. A spring 308 is sleeved on the outside of the adjusting rod 311. The top end of the spring 308 is fixedly connected to the support plate 307, and the bottom end of the spring 308 is fixedly connected to the outer surface of the adjusting rod 311.

[0032] A reciprocating screw 310 is provided between two fixed plates 305. One end of the reciprocating screw 310 is rotatably connected to the surface of the adjacent fixed plate 305, and the other end of the reciprocating screw 310 passes through the adjacent fixed plate 305 and is provided with a first transmission mechanism 304. A limit rod 309 is fixedly connected between the two fixed plates 305. A slider 306 is threadedly connected to the reciprocating screw 310. A limit through hole is opened on the surface of the slider 306. The other end of the limit rod 309 is slidably connected to the inner wall of the limit through hole. A guide ring 303 is fixedly connected to the bottom of the slider 306.

[0033] A motor 301 is provided on the top of the base 1. The output shaft of the motor 301 is fixedly connected to the other end of the first transmission mechanism 304. A mounting plate is fixedly connected to the side of the first transmission mechanism 304 away from the motor 301. A take-up roller 302 is provided on the other side of the mounting plate. In a preferred embodiment, the take-up roller 302 is coaxially fixedly connected to the mounting plate.

[0034] By starting the motor 301, the first transmission mechanism 304, the mounting plate, and the take-up roller 302 can be rotated, enabling the copper wire to be wound up. The first transmission mechanism 304 is a common technology in existing applications, consisting of two transmission wheels and a transmission belt. By rotating one of the transmission wheels, the other transmission wheel can be rotated synchronously under the action of the transmission belt, thereby achieving the effect of rotating the reciprocating screw 310. The reciprocating screw is a screw that can make the slider reciprocate without changing the rotation direction of the main shaft. The reciprocating screw is represented by two threaded grooves with the same pitch and opposite directions, connected at both ends by a transition curve. By rotating the reciprocating screw, the side of the spiral groove pushes the slider placed in the spiral groove to make axial reciprocating motion. In this process, the slider 306 can be moved back and forth, thereby changing the position of the guide ring 303. The copper wire passes through the guide ring 303 and is then fixed on the take-up roller 302. The reciprocating movement of the guide ring 303 enables the copper wire to be wound up better on the take-up roller 302. During the winding process, the adjusting roller 312 contacts the surface of the copper wire. Specifically, the adjusting roller 312 can roll against the surface of the copper wire, so that when the surface tension of the copper wire changes, the spring 308 applies pressure to it to overcome the possibility of loosening or even falling off due to increased tension, thereby improving the rolling effect.

[0035] Working principle: The coil to be processed is wound onto the surface of the unwinding roller 101. Before processing, its free end passes through the rolling mechanism 2 and is fixed to the surface of the winding mechanism 3. The winding mechanism 3 is started to perform rolling operations. During this process, the copper wire passes through the rolling groove 207 between the two rolling rollers 206. During the winding process, it is squeezed by the rolling groove 207 to achieve the effect of rolling processing. The depth of the rolling groove 207 decreases from left to right, which can gradually process the copper wire to the required specifications. The stepwise decrease can reduce the resistance during the movement of the copper wire. During winding, there is no need for a high-power motor 301 to provide excessive traction force, thereby reducing the operating cost. The high tensile force required for one-time forming is dispersed into multi-stage small-amplitude processing, reducing the load on the equipment. At the same time, the copper wire passing between the two lubrication blocks 209 can be coated with lubricating oil, which facilitates lubrication and cooling during the rolling process. During the adjustment of the upper rolling roller 206, the upper connecting plate 208 can be moved synchronously through the fixed rod 214 and the connecting rod 205, so that the two lubrication blocks 209 can be separated from each other, which facilitates the passage of copper wire. Furthermore, when the lubricating oil coated on the surface of the copper wire is squeezed during the rolling process, it will remain inside the rolling groove 207 and eventually drip into the oil groove 102 for reuse, avoiding the problem of lubricating oil dripping during the rolling process in traditional rolling equipment, which is not conducive to cleaning.
