[0028] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0029] In order to achieve the above-mentioned invention object, the utility model provides a copper wire drawing machine, such as Figure 1-Figure 7 As shown, including:

[0030] The operating table 1 is provided with a feeding roller 12, a base 13, a first motor 14, and a receiving roller 15. The feeding roller 12 is rotatably connected to the side of the top of the operating table 1. The base 13 is arranged on the other side of the top of the operating table 1. The base 13 is provided with a first motor 14. The receiving roller 15 is detachably connected to the output end of the first motor 14 coaxially.

[0031] The wire drawing chamber 2 is located at the top of the operating table 1. A first chamber is provided above the wire drawing chamber 2. A slope is provided at the bottom end of the first chamber. The wire drawing chamber 2 is provided with a limit plate 21, a wire drawing die 22, and a pressure plate 23. The limit plates 21 are symmetrically arranged on the two side walls of the first chamber. The bottom end of the pressure plate 23 is fixed to the slope at intervals. The wire drawing die 22 is respectively placed between the limit plate 21 and the pressure plate 23 and between adjacent pressure plates 23. The pressure plate 23 is provided with a slide bar 231 and a buffer pad 232. A groove is provided on the side of the pressure plate 23 facing the wire drawing die 22. A slide bar 231 is provided in the groove. One end of the slide bar 231 is slidably connected with the pressure plate 23. The other end of the slide bar 231 is fixedly connected with a buffer pad 232. The buffer pad 232 is parallel to the pressure plate 23.

[0032] The grinding chamber 3 is located at the top of the operating table 1. A second chamber is provided in the grinding chamber 3. The grinding chamber 3 is provided with multiple third motors 32, grinding wheels 33 and pressure wheels 34. The third motor 32 is provided on the outer wall of the grinding chamber 3. The output end of the third motor 32 passes through the side wall of the grinding chamber 3 toward the inside of the grinding chamber 3. The grinding wheel 33 is coaxially fixed to the output end of the third motor 32. The grinding wheels 33 are arranged at intervals. The pressure wheel 34 is symmetrical to the grinding wheel 33 in upper and lower directions. The pressure wheel 34 is rotatably connected to the inner wall of the grinding chamber 3.

[0033] In this embodiment, the limiting plate 21, the drawing die 22 and the pressure plate 23 are provided with holes adapted to the through hole to facilitate the copper wire to pass through. The copper wire is released from the discharge roller 12, and first passes through the through hole of the drawing chamber 2 to enter the drawing chamber 2. The copper wire passes through the limiting plate 21, the drawing die 22 and the holes in the pressure plate 23 in turn. Copper wires of different sizes can be drawn through the holes of the drawing die 22 of different sizes. During the drawing operation, the copper wire contacts the holes in the drawing die 22, and the copper wire squeezes the drawing die 22 with force. The wire drawing die 22 contacts the buffer pad 232 on the side wall of the pressure plate 23, and the slide bar 231 behind the buffer belt slides with the pressure plate 23 to provide buffering and protection for the wire drawing die 22. The copper wire after wire drawing enters the grinding chamber 3, and the copper wire passes between the grinding wheel 33 and the pressure wheel 34. The third motor 32 is started to drive the grinding wheel 33 to rotate and cooperate with the pressure wheel 34 to grind the residue on the surface of the copper wire. After grinding, the copper wire is wound around the receiving roller 15, and the first motor 14 is started to be wound.

[0034] In an optional embodiment, the wire drawing chamber 2 is further provided with a water pump 24, a water pipe 25 and a water storage chamber 26. The water storage chamber 26 is located at the lower part of the wire drawing chamber 2. The water pump 24 is installed on the outer wall of the wire drawing chamber 2. The water pump 24 is provided with a water pumping pipe 241. One end of the water pumping pipe 241 is connected to the water storage chamber 26. The other end of the water pumping pipe 241 is connected to the input end of the water pump 24. One end of the water pipe 25 is connected to the output end of the water pump 24. A water sprayer is arranged at the other end of the water pipe 25. The water sprayer is located at the top of the wire drawing chamber 2 and faces the slope. A through groove connected to the water storage chamber 26 is provided at the lower end of the slope, and the top of the through groove is covered with a filter 261.

[0035] In this embodiment, when the copper wire is being drawn, the water pump 24 draws water from the water storage chamber 26 through the water pumping pipe 241, and the water delivery pipe 25 delivers water to the sprinkler. The sprinkler sprays and flushes the copper wire surface and the drawing die 22 to cool down and clean the residue on the copper wire surface. After cleaning, excess water is accelerated through the slope to flow into the through groove and into the water storage chamber 26 for recycling, and the residue is left in the filter 261 waiting to be cleaned.

[0036] An optional embodiment further includes an adjusting component, which includes a fourth motor 51 and a slider 52. The fourth motor 51 is arranged on the side of the grinding chamber 3 close to the base 13. The fourth motor 51 is provided with a screw rod 511 and a limit rod 512. The screw rod 511 passes through the top of the slider 52 and is coaxially connected to the output end of the fourth motor 51. The slider 52 is rotatably connected to the screw rod 511. The limit rod 512 passes through both sides of the top of the slider 52. A tensioning wheel 521 is provided at the bottom of the slider 52, and the tensioning wheel 521 is rotatably connected to the slider 52.

[0037] In this embodiment, when the output end of the fourth motor 51 rotates, the screw rod 511 rotates, and the slider 52 is rotationally connected to the screw rod 511. The rotation of the slider 52 is limited by the limit rod 512, and the slider 52 can be controlled to move in translation, thereby controlling the tensioning wheel 521 under the slider 52 to move in translation, so that the copper wire after wire drawing and grinding can be evenly wound on the receiving roller 15.

[0038] The overall working principle: the first electric push rod 11 can adjust the height of the discharge roller 12. When the height is preset, the copper wire is released from the discharge roller 12, and is pulled to the wire drawing chamber 2 through the first guide pulley 27, and enters the room through the through hole of the wire drawing chamber 2, so as to pass through the holes in the limit plate 21, the wire drawing die 22 and the pressure plate 23. The copper wire is drawn when passing through the holes customized by the wire drawing die 22. The copper wire applies force to the wire drawing die 22, so that the wire drawing die 22 squeezes the buffer pad 232, and cooperates with the slide rod 231 for protection. At the same time, the water pump 24 draws water from the water storage chamber 26, and sprays it through the water pumping pipe 241 and the water delivery pipe 25 through the sprinkler. To the copper wire surface and the drawing die 22, the sprayed water is accelerated to flow into the through groove through the slope, and the water can be guided into the water storage chamber 26 through the through groove. The washed residue is isolated by the filter screen 261. When the copper wire after drawing passes through the through hole, the cleaning pad 29 is used to wipe off the excess water, and then the active wheel 18 assists in applying force, and enters the grinding chamber 3 through the second guide wheel 31, and passes through the grinding wheel 33 and the pressure wheel 34 in turn. The excess residue on the surface of the copper wire is polished and falls into the dust collecting cover 35 below, and is collected in the dust collecting box 4. The polished copper wire is evenly rolled up on the receiving roller 15 by the slider 52 in the adjustment component.
