Description

Technical Field

[0001] The invention relates to the technical field of wire stranding equipment, in particular to a copper enameled wire stranding device. Background Art

[0002] Copper enameled wire is often used to make electromagnetic coils, which are key components for generating electromagnetic force. For example, this type of enameled wire coil is needed in the clutch of automobile air conditioners. When current passes through the electromagnetic coil, a magnetic field is generated around the coil to attract or release the drive plate to achieve the engagement and disengagement of the clutch. In addition, in the process of making the clutch, in order to increase the electromagnetic force generated by the enameled wire coil, it is usually necessary to connect multiple copper enameled wire coils in parallel. The process of connecting coils in parallel is the process of fixing the wire ends of the coils together through a twisting process. Since the surface of the copper enameled wire has an insulating layer, when the enameled wire is twisted, the insulating layer on the surface of the copper enameled wire needs to be scraped out first, and then twisted.

[0003] The existing copper enameled wire twisting device scrapes off the insulating layer on the surface of the enameled wire with a scraper and then directly performs the twisting process. However, part of the insulating layer will still adhere to the surface of the enameled wire after being scraped off. Therefore, some insulating layer debris will be twisted into the enameled wire during twisting, resulting in poor contact of the enameled wire ends, causing heating of the wire ends during subsequent use, which poses a certain safety risk. Therefore, it does not meet the existing needs. In this regard, we propose a copper enameled wire twisting device. Summary of the invention

[0004] The present invention provides a copper enameled wire twisting device, which has the function of shaking the enameled wire after the insulating layer on the surface of the enameled wire is scraped off, so as to shake off the insulating layer debris on the surface of the enameled wire and prevent the insulating layer debris from being twisted into the enameled wire, thereby preventing the enameled wire ends from having poor contact, preventing the risk of the wire ends heating up, and improving the beneficial effect of safety. It solves the problem that the existing copper enameled wire twisting device mentioned in the above background technology directly performs the twisting process after the insulating layer on the surface of the enameled wire is scraped off with a scraper, but part of the insulating layer will still adhere to the surface of the enameled wire after being scraped off. Therefore, some insulating layer debris will be twisted into the enameled wire during the twisting, resulting in poor contact of the enameled wire ends, causing the wire ends to heat up during subsequent use, and posing certain safety risks.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Embodiment 1: This embodiment is intended to promote the solution of the existing copper enameled wire stranding device. After the insulation layer on the surface of the enameled wire is scraped off with a scraper, the stranding process is directly carried out. However, part of the insulation layer will still adhere to the surface of the enameled wire after being scraped off. Therefore, when stranding, some debris from the insulation layer will be twisted into the enameled wire, causing poor contact of the enameled wire ends, causing the wire ends to heat up during subsequent use, which has certain safety risks. Please refer to Figures 1 to 10 A copper enameled wire stranding device, comprising a housing 101, a stranding plate 102 for stranding wires is arranged inside the housing 101, a scraping mechanism 100 for scraping off the insulating layer of the enameled wires is arranged inside the housing 101, a motor 202 for driving the stranding plate 102 to rotate is arranged inside the housing 101, the scraping mechanism 100 comprises an upper scraper 103 and a lower scraper 104, a vertical plate 201 is arranged inside the housing 101, the upper scraper 103 and the lower scraper 104 are slidably mounted on the vertical plate 201, and the lower scraper 104 The upper scraper 103 and the lower scraper 104 are connected to the motor 202 for transmission, and move synchronously. A wire shaking mechanism 200 is arranged on the vertical plate 201, and the wire shaking mechanism 200 includes a No. 1 tension spring 232 arranged on the side of the vertical plate 201. The upper scraper 103 and the lower scraper 104 move in the opposite direction after scraping off the insulating layer on the surface of the enameled wire. The No. 1 tension spring 232 accumulates force. Under the action of the No. 1 tension spring 232, the upper scraper 103 and the lower scraper 104 move quickly away from the stranding plate 102, and at the same time shake off the insulating layer debris on the surface of the enameled wire.

[0031] It should be noted that the stranding plate 102 is provided with a through hole for inserting the enameled wire. When stranding the wire, the worker holds the coil, and under the action of the motor 202, the stranding plate 102 can move while rotating (the connection structure between the motor 202 and the stranding plate 102 is prior art and is therefore not drawn in the figure), thereby twisting the wire ends of the coil together.

[0032] For details, please refer to Figure 5 , lower plates 226 are installed at both ends of the lower scraper 104, upper plates 217 are installed at both ends of the upper scraper 103, a positioning rod 209 is installed on the lower plate 226, and the upper plate 217 is slidably mounted on the positioning rod 209, a No. 2 tension spring 210 is connected between the lower plate 226 and the upper plate 217, and the No. 2 tension spring 210 is mounted on the positioning rod 209, an upper cross bar 215 is installed on one side of the upper plate 217, and a lower cross bar 221 is installed on the side of the lower plate 226 away from the lower scraper 104, a guide groove 227 is opened on the vertical plate 201, and the upper cross bar 215 and the lower cross bar 221 are slidably mounted in the guide groove 227, and a collecting box 213 for collecting the enameled wire skin is provided on the side of the vertical plate 201, and the collecting box 213 is located directly below the enameled wire.

[0033] Among them, please refer to Figure 7The guide groove 227 includes a No. 1 horizontal groove 228, an oblique groove 229 and a No. 2 horizontal groove 230. The No. 1 horizontal groove 228, the oblique groove 229 and the No. 2 horizontal groove 230 are connected in sequence. When the upper cross bar 215 and the lower cross bar 221 slide from the No. 1 horizontal groove 228 into the oblique groove 229 respectively, the upper scraper 103 and the lower scraper 104 jointly clamp the enameled wire. When the upper cross bar 215 and the lower cross bar 221 slide in the No. 2 horizontal groove 230 respectively, the upper scraper 103 and the lower scraper 104 jointly scrape off the insulating layer on the surface of the enameled wire.

[0034] Among them, a pair of guide grooves 227 are provided, which are respectively used to guide the upper cross bar 215 and the lower cross bar 221. In order to achieve the effect that when the upper cross bar 215 and the lower cross bar 221 slide from the No. 1 horizontal groove 228 into the oblique groove 229 respectively, the upper scraper 103 and the lower scraper 104 jointly clamp the enameled wire, the distance between a pair of No. 2 horizontal grooves 230 is smaller than the distance between a pair of No. 1 horizontal grooves 228.

[0035] Also, please refer to Figure 5 A No. 1 slide groove 216 is provided inside the casing 101, and a No. 1 slider 205 is slidably installed on the No. 1 slide groove 216. A pull rod 220 for pulling the lower scraper 104 to move is installed on the No. 1 slider 205. A pull plate 218 is provided on the lower scraper 104, and the pull rod 220 is slidably plugged with the pull plate 218. A driving gear 203 is installed on the output shaft of the motor 202, and a support plate 212 is provided inside the casing 101. A pair of transmission rods 219 are rotatably installed on the support plate 212, and one end of the pair of transmission rods 219 are respectively installed with a No. 1 transmission gear 204 and a No. 2 transmission gear 214, and the No. 1 transmission gear 204 and the No. 2 transmission gear 214 are respectively meshed with the driving gear 203.

A reset gear 206 is installed on the other end of the transmission rod 219 connected to the No. 2 transmission gear 214, and the reset gear 206 is meshed with the lower teeth of the rack 208. Both the forward gear 207 and the reset gear 206 are set as incomplete gears. When the forward gear 207 is meshed with the rack 208, the rack 208 moves away from the stranded wire plate 102, and when the reset gear 206 is meshed with the rack 208, the rack 208 moves toward the stranded wire plate 102.

[0037] Please note that, please refer to Fig.10, the forward gear 207 and the reset gear 206 are both configured as incomplete gears, and the forward gear 207, the reset gear 206 and the rack 208 are not meshed at the same time. Specifically, scraping the insulation layer of the enameled wire includes the following process: when the forward gear 207 is meshed with the rack 208, the rack 208 moves in a direction away from the stranding plate 102, at which time the upper scraper 103 and the lower scraper 104 jointly scrape the insulation layer on the surface of the enameled wire; when the reset gear 206 is meshed with the rack 208 (at this time the upper scraper 103 and the lower scraper 104 still clamp the enameled wire), the rack 208 moves toward the stranding plate 102, and the upper scraper 103 and the lower scraper 104 will make the enameled wire clamped. The enameled wire is bent; when the forward gear 207, the reset gear 206 and the rack 208 are not engaged, the upper scraper 103 and the lower scraper 104 are quickly reset under the action of the No. 1 tension spring 232, and the previously bent enameled wire is quickly straightened, and at the same time, the insulating layer debris attached to the surface of the enameled wire is shaken off; then the forward gear 207 is engaged with the rack 208 again, and the rack 208 moves away from the stranding plate 102, the upper scraper 103 and the lower scraper 104 are disengaged from the enameled wire, and then the stranding plate 102 is stranded; after the stranding is completed, the reset gear 206 is engaged with the rack 208 again, and the upper scraper 103 and the lower scraper 104 are reset through the rack 208.

[0038] Please refer to Figure 6 , Figure 8 A No. 2 slide groove 211 is provided on the side of the vertical plate 201, and a No. 2 slider 233 is slidably installed in the No. 2 slide groove 211. A rotating plate 235 is hinged on the No. 2 slider 233, and a torsion spring 234 is provided at the bottom end of the rotating plate 235. One end of the torsion spring 234 is connected to the rotating plate 235, and the other end of the torsion spring 234 is connected to the No. 2 slider 233. A mounting plate 231 is installed on the side of the vertical plate 201, one end of the No. 1 tension spring 232 is fixedly connected to the mounting plate 231, and the other end of the No. 1 tension spring 232 is fixedly installed on the No. 2 slider 233.

[0039] Please refer to Figure 5 , Fig. 9 A sleeve 223 is provided at one end of the lower cross bar 221, a wedge block 222 is slidably installed in the sleeve 223, a No. 1 compression spring 236 is provided in the sleeve 223, one end of the No. 1 compression spring 236 is connected to one end of the wedge block 222, and the wedge block 222 is intermittently engaged with the rotating plate 235.

[0040] In this embodiment: after the motor 202 is started, the forward gear 207 is driven to rotate by meshing the driving gear 203 and the No. 1 transmission gear 204. At this time, the forward gear 207 is meshed with the rack 208, while the reset gear 206 is not meshed with the rack 208. The upper cross bar 215 and the lower cross bar 221 slide from the No. 1 horizontal groove 228 into the oblique groove 229. Under the action of the No. 2 tension spring 210, the upper scraper 103 and the lower scraper 104 jointly clamp the enameled wire, and then scrape off the insulating layer on the surface of the enameled wire. After the insulating layer is scraped off, the forward gear 207 is no longer meshed with the rack 208, and the reset gear 206 is meshed with the rack 208, so the rack 208 moves in the opposite direction. At this time, the wedge Block 222 is engaged with rotating plate 235, wedge block 222 drives slider No. 233 to move, tension spring No. 1 232 is stretched and stored, when reset gear 206 is not engaged with rack 208, tension spring No. 1 232 is reset, and slider No. 233 is quickly pulled to move, further driving wedge block 222 to move quickly, and then lower scraper 104 is driven to move quickly through lower cross bar 221, at this time, the enameled wire is quickly pulled by upper scraper 103 and lower scraper 104, and the insulating layer debris on the surface of the enameled wire is shaken off, so as to prevent the debris from being twisted into the enameled wire head during subsequent twisting, and to prevent the enameled wire head from heating up due to poor contact, thereby improving the reliability and safety of the enameled wire head after twisting.

[0041] Embodiment 2: This embodiment is intended to promote the solution of the problem that the upper scraper 103 and the lower scraper 104 will pull the enameled wire when scraping off the insulation layer of the enameled wire, and the enameled wire coil needs to be fixed manually. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figures 1 to 10 A fixing plate 301 is installed on the side of the housing 101 , a positioning column 305 is installed on the fixing plate 301 , a pressing plate 302 for pressing and fixing the enameled wire is slidably installed on the positioning column 305 , and the pressing plate 302 is transmission-connected to the upper cross bar 215 .

[0042] Please refer to Figure 1 A No. 2 compression spring 304 is provided on the positioning column 305, and the bottom end of the No. 2 compression spring 304 is in conflict with the pressure plate 302. Connecting rods 303 are respectively installed at both ends of the pressure plate 302. When the upper cross bar 215 is located in the No. 1 horizontal groove 228, one end of the connecting rod 303 is in conflict with the upper cross bar 215. When the upper cross bar 215 is located in the oblique groove 229, the pressure plate 302 presses the enameled wire onto the fixed plate 301 under the action of the connecting rod 303. A rubber pad 306 is provided at the bottom of the pressure plate 302. When the pressure plate 302 presses the enameled wire, the rubber pad 306 prevents the enameled wire from sliding.

[0043] In the present embodiment: when the upper cross bar 215 slides from the No. 1 horizontal groove 228 to the oblique groove 229, the upper cross bar 215 and the connecting rod 303 no longer conflict with each other. At this time, the pressure plate 302 presses the end of the enameled wire onto the fixed plate 301 under the action of the No. 2 compression spring 304, so that in the process of scraping and twisting the enameled wire, it is no longer necessary to manually hold and fix the enameled wire, which reduces manpower operation and improves the practicality of the device.

[0044] Embodiment 3: This embodiment is intended to further solve the problem of removing the insulating layer debris attached to the surface of the enameled wire. This embodiment is an improvement made on the basis of Embodiment 2. For details, please refer to Figures 1 to 10 An airbag 401 is arranged on the side of the vertical plate 201, a one-way valve 402 is arranged at the air inlet of the airbag 401, a hose 403 is installed at the air outlet of the airbag 401, one end of the hose 403 is located directly above the enameled wire, and a fixing sleeve 404 for fixing the hose 403 is installed on the upper scraper 103. When the upper cross bar 215 slides in the second horizontal groove 230, one end of the upper cross bar 215 contacts the airbag 401, and the airbag 401 blows off the insulating layer debris on the surface of the enameled wire through the hose 403, wherein the airbag 401 is arranged as a rubber airbag with a spring inside, and the airbag 401 can automatically recover under the action of the spring after being exhausted.

[0045] It should be noted that the one-way valve 402 includes a sleeve and a rotating plate hinged in the sleeve. The rotating plate is rotated in one direction by a spring, so the gas can only pass through the one-way valve 402 in one direction. The specific structure and principle of the one-way valve 402 are well known to those skilled in the art and will not be elaborated here.

[0046] In the present embodiment: when the upper cross bar 215 slides in the second horizontal groove 230, one end of the upper cross bar 215 contacts the airbag 401. At this time, the airbag 401 exhausts air outwards through the hose 403. The gas blown out by the hose 403 blows off the insulating layer debris attached to the surface of the enameled wire, preventing the debris from being rolled into the enameled wire ends, thereby further improving the reliability and safety of the enameled wire ends after twisting.

[0047] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0048] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
