DETAILED DESCRIPTION
[0018] The technical solution is further described below in conjunction with specific embodiments. It should be noted that the words indicating directions such as up, down, left, and right mentioned in this article are only for the position of the structure shown in the corresponding drawings. The serial numbers of the parts in this article, such as first, second, etc., are only used to distinguish the objects described and do not have any order or technical meaning. The words such as connection and coupling in this application include direct and indirect connection (coupling) unless otherwise specified.
[0019] Embodiment 1: A silver-plated copper wire auxiliary stretching device, such as Figure 1-Figure 4As shown, it includes a processing table 10, a mounting base plate 101, a first bracket 102, a second bracket 11, a gear mounting disk 13 and an extrusion wheel 131. The processing table 10 is connected to the mounting base plate 101 on one side, and is connected to a group of first brackets 102 on the other side, wherein the first bracket 102 away from the motor 16 (mentioned below) is slidably arranged along the axial direction of the reciprocating screw 17 through a slide groove; the mounting base plate 101 is connected to the second bracket 11, and the second bracket 11 is connected to a pair of gear mounting disks 13 that are symmetrically rotated up and down, and the two gear mounting disks 13 are driven by gear meshing, and a self-locking adjustment locking mechanism is connected to the gear mounting disk 13 located at the bottom, and the gear mounting disk 13 is connected to 6 openings that are evenly rotated in the circumferential direction. The extrusion wheels 131 with wire grooves are pressed and matched with each other on the upper and lower gear mounting plates 13. The wire groove diameters of the extrusion wheels 131 are set to 6 sizes. The wire groove diameters of each group of extrusion wheels 131 that are pressed and matched with each other on the upper and lower gear mounting plates 13 correspond to each other. By adjusting the locking mechanism, the gear mounting plate 13 can be rotated so that the extrusion wheels 131 rotate with the gear mounting plate 13. When each group of upper and lower extrusion wheels 131 with the same wire grooves are in contact, they just form a diameter through hole of the silver-plated copper wire. Under the tension of the wire receiving end, the silver-plated copper wire is stretched and thinned to the required diameter through the through-hole limiting extrusion between the extrusion wheels 131 and the auxiliary transmission function of the extrusion wheels 131.
[0020] like Figure 3 and Figure 4 As shown, the adjustment locking mechanism includes a worm wheel 12, a worm 121 and a rotating wheel 122. The gear mounting plate 13 located below is keyed to the worm wheel 12 through a rotating shaft. A worm 121 that cooperates with the worm wheel 12 is mounted on the mounting base plate 101 through a bracket, and a rotating wheel 122 is connected to the end of the worm 121. Manually rotate the rotating wheel 122 to drive the worm 121 to rotate, thereby rotating the worm wheel 12, thereby driving the gear mounting plate 13 to rotate, thereby rotating the extrusion wheel 131 with wire grooves of different diameters. When the upper and lower extrusion wheels 131 are in contact, an extrusion through hole for the silver-plated copper wire is formed, which is convenient for subsequent stretching operations.
[0021] As a more preferred implementation scheme, the adjustment locking mechanism includes a group of plug-in holes and plug-in columns, the hole is opened on the gear mounting plate 13, and the plug-in column is slidably plugged into the second bracket 11. When the gear mounting plate 13 and the extrusion wheel 131 are rotated to the required position, the plug-in column slidably plugged on the second bracket 11 is inserted into the hole on the gear mounting plate 13, thereby fixing the position of the gear mounting plate 13 and the extrusion wheel 131.
[0022] like Figure 5 and Figure 6As shown, it also includes a sponge wheel 14, a lubricating oil pump 15 and a lubricating oil pipe 151.

The side wall of the second bracket 11 is provided with a lubricating oil pump 15. The lubricating oil pump 15 and the sponge wheel 14 are connected by a lubricating oil pipe 151. Lubricating oil is injected into the sponge wheel 14 through the lubricating oil pump 15 and the lubricating oil pipe 151, which can prevent the extrusion wheel 131 from scraping off the silver coating of the silver-plated copper wire and clean some impurities on the extrusion wheel 131.
[0023] like Figure 7 and Figure 8 As shown, it also includes a motor 16, a pulley assembly 161, a reciprocating screw rod 17, a guide rod 171, a bushing 172, a winding drum 173, a spur gear 174 and a long gear 175. The processing table 10 is installed with a motor 16, and a long gear 175 and a reciprocating screw rod 17 with a bidirectional thread are rotatably connected between the first bracket 102. The reciprocating screw rod 17 and the long gear 175 are connected and transmitted to the motor 16 through the pulley assembly 161. The pulley assembly 161 uses a tooth surface for transmission to increase transmission friction; the reciprocating screw rod 17 is threadedly connected with a bushing 172, and a guide block for changing the direction of the reciprocating screw rod 17 at the end thereof is arranged in the bushing 172. The first bracket 102 is connected with a guide rod 171, and the bushing 172 is slidably connected to the guide rod 171. A winding drum 173 is sleeved on the outer wall of the bushing 172. When the winding drum 173 needs to be taken and placed, the first bracket 102 away from the motor 16 is slid out along the slide groove in the direction away from the processing table 10 to facilitate the removal of the winding drum 173 from the bushing 172. A spur gear 174 is connected to one side of the winding drum 173, and the spur gear 174 is meshed with the long gear 175 for transmission. After starting the motor 16, under the transmission of the pulley assembly 161, the reciprocating screw rod 17 and the long gear 175 rotate, and the guide block in the bushing 172 slides back and forth along the thread of the reciprocating screw rod 17, thereby driving the bushing 172 and the winding drum 173 to slide left and right along the guide rod 171. At the same time, the long gear 175 rotates to drive the spur gear 174 and the winding drum 173 to rotate, thereby realizing the stretching and winding of the silver-plated copper wire.

A guide groove 176 is provided on the guide rod 171. The connecting rod 18 is hinged on the first bracket 102 away from the motor 16. The paint brush 181 and the paint pump 182 are installed at the end of the connecting rod 18 for applying a protective layer to the surface of the silver-plated copper wire. The guide block 183 is slidably inserted in the guide groove 176. The guide block 183 and the connecting rod 18 A stretching rod 184 is connected between them, and a torsion spring 185 is connected between the connecting rod 18 and the first bracket 102. When the bushing 172 slides to the left end along the guide rod 171, it will gradually squeeze the guide block 183 to make it slide down into the guide groove 176, so that the stretching rod 184 will pull the connecting rod 18, the paint brush 181 and the paint pump 182 downward to approach the silver-plated copper wire on the winding reel 173. When the paint brush 181 contacts the silver-plated copper wire, a protective coating can be applied to the surface of the silver-plated copper wire.
[0025] like Fig.11 As shown, an annealing box 19 and a material guide sleeve 191 are also included. The annealing box 19 is provided on the processing table 10. The material guide sleeve 191 is rotatably inserted in the annealing box 19. The silver-plated copper wire is passed through the material guide sleeve 191. The annealing box 19 works and can anneal the silver-plated copper wire before winding it up, so as to better wind the silver-plated copper wire.
[0026] like Fig.12 As shown, a heat dissipation fan 20 is also included. The heat dissipation fan 20 is arranged at the lower right side of the processing table 10. A heat dissipation hole 201 is opened on the panel of the processing table 10 above the heat dissipation fan 20.
