Description

Technical Field

[0001] The present invention relates to a field of intelligent tension adjustment device for a copper wire intermediate drawing machine and a method thereof. Background Art

[0002] The main function of the copper wire drawing machine is to stretch large-diameter copper wire into small-diameter copper wire. The copper wire drawing machine is widely used in the fields of wires and cables, communications electronics, automotive accessories, etc. It has high precision and high reliability, and can meet the needs of various copper wire drawing, providing a strong guarantee for the production of efficient and high-quality products.

[0003] During the intermediate drawing process of the existing intermediate drawing machine, the main machine controls the operation of the stretching head, the motor drives the stretching head to rotate at high speed, and the working pressure of the stretching head is controlled by the hydraulic system, so that the copper wire is gradually stretched through the stretching head, and finally the required small diameter copper wire is formed.

[0004] During the stretching process, the hydraulic system is controlled by pressure, and the hydraulic pressure is controlled by pressure to adjust the tension of the tension frame. When the air pressure is unstable, the tension adjustment of the tension frame fluctuates, and during the stretching process, the surface of the copper wire will be squeezed by iron filings, and the surface of the copper wire will be concave, affecting the quality of the copper wire. Summary of the Invention

[0005] The purpose of the present invention is to provide an intelligent tension adjustment device and adjustment method for a copper wire intermediate drawing machine in order to solve the problem that when the air pressure is unstable, the tension adjustment of the tension frame fluctuates when the tension is adjusted by pressure, and the surface of the copper wire is squeezed by iron filings during the stretching process, resulting in a concave state on the surface of the copper wire, which affects the quality of the copper wire.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an intelligent tension adjustment device for a copper wire drawing machine and an adjustment method thereof, comprising a fixed plate, two tension frames are arranged inside the fixed plate, a fixed cylinder is fixed at the end of the tension frame, a rotating shaft is arranged inside the fixed cylinder, a piston cylinder is arranged on one side of the outer side of the rotating shaft, a connecting plate is arranged on the other side of the rotating shaft, both ends of one side of the connecting plate are rotatably connected to a brush column, a mounting plate is fixed to the middle part of the fixed plate, a cylinder is installed on the top of the mounting plate, and the top of the cylinder is rotatably connected to two connecting rods, the copper wire passes through the guide roller, the No. 1 roller, and the No. 2 roller, and the end of the copper wire is connected to the external take-up roller, the copper wire is pulled to move by the rotation of the take-up roller, and the cylinder is started to pull the connecting rod downward.

[0007] As a further solution of the present invention: a fixing frame is fixed on one side of the mounting plate, and the connecting rod pulls the ends of crank No. 1 and crank No. 2 to move the end of crank No. 1 toward the position of the fixing frame, the top of the fixing frame is rotatably connected to roller No. 1, and the inner wall of the fixing cylinder is provided with a sliding groove.

[0008] As a further solution of the present invention: the head end of the tension frame is rotatably connected to one side of the fixed frame, the No. 1 crank pulls the No. 2 crank to move toward the position of the fixed frame, and the No. 2 crank pulls the tension frame toward the position of the fixed frame, so that the distance between the No. 2 roller and the No. 1 roller in the tension frame is changed, and the end of the connecting rod is rotatably connected to the No. 1 crank and the No. 2 crank.

[0009] As a further solution of the present invention: the end of the No. 1 crank is rotatably connected to the fixed frame, and the end of the No. 2 crank is rotatably connected to the tension frame. By mechanically adjusting the distance between the No. 2 roller and the No. 1 roller, tension adjustment fluctuations are prevented when adjusting the tension frame.

[0010] As a further solution of the present invention: a slider is fixed on one side of the outer side of the rotating shaft, and a circulating curved groove is provided on the other side of the outer side of the rotating shaft. When the rotating shaft slides left and right, it drives the connecting plate to slide left and right, and the connecting plate drives the brush column to slide left and right to clean the copper wire and the copper chips on the surface of the No. 2 roller. The slider is slidably connected to the inside of the slide groove, and a spray pipe is provided on the top of the piston cylinder.

[0011] As a further solution of the present invention: a plurality of guide rollers are provided on the top of the interior of the fixed plate, and a copper wire is provided on the outside of the guide roller. When the rotating shaft slides left and right, the piston cylinder is pushed to spray oil from the spray pipe onto the No. 2 roller and the copper wire to lubricate the copper wire and prevent it from breaking. An oil tank is provided on one side of the piston cylinder inside the fixed plate.

[0012] As a further solution of the present invention: a one-way valve is provided on the top of the oil tank, and the rotating shaft slides left and right. Since the slider on the outside of the rotating shaft is slidably connected to the slide groove, the rotating shaft pulls the piston cylinder when it slides left and right, and the piston cylinder sucks out the oil inside the oil tank. The other side of the oil tank is connected to the piston cylinder.

[0013] As a further solution of the present invention: the outer side of the fixed cylinder is rotatably connected to the No. 2 roller, the inner wall of the No. 2 roller is fixed with an extrusion column, and the extrusion column is slidably connected to the inside of the circulation curved groove.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The connecting rod is pulled downward by the provided cylinder, and the connecting rod pulls the ends of the No. 1 crank and the No. 2 crank, so that the end of the No. 1 crank moves toward the position of the fixed frame. The No. 1 crank pulls the No. 2 crank to move toward the position of the fixed frame. The No. 2 crank pulls the tension frame toward the position of the fixed frame, so that the distance between the No. 2 roller and the No. 1 roller in the tension frame is changed. The distance between the No. 2 roller and the No. 1 roller is adjusted mechanically to prevent tension adjustment fluctuations when adjusting the tension frame.

[0016] 2. The No. 2 roller rotates with the rotating ring, which squeezes the circular curved groove inside the shaft through the squeezing column, causing the shaft to slide left and right. Because the slider on the outside of the shaft is slidingly connected to the sliding groove, the left and right sliding of the shaft pulls the piston cylinder, which draws oil from the oil tank. The left and right sliding of the shaft pushes the piston cylinder, causing the oil to be sprayed from the spray pipe onto the No. 2 roller and the copper wire, lubricating the copper wire and preventing breakage. The left and right sliding of the shaft drives the connecting plate to slide left and right, which in turn drives the brush column to slide left and right, cleaning the copper wire and copper chips on the surface of the No. 2 roller.

The copper wire 404 passes through the guide roller 101, the No. 1 roller 202, and the No. 2 roller 3, and the end of the copper wire 404 is connected to the external take-up roller. The copper wire 404 is pulled to move by the rotation of the take-up roller. The cylinder 4 is started to pull the connecting rod 401 downward. A fixing frame 201 is fixed to one side of the mounting plate 2. The connecting rod 401 pulls the ends of the No. 1 crank 203 and the No. 2 crank 204, so that the end of the No. 1 crank 203 moves toward the position of the fixing frame 201.

[0025] The top of the fixed frame 201 is rotatably connected to the No. 1 roller 202, and the inner wall of the fixed cylinder 206 is provided with a slide groove 207. The head end of the tension frame 205 is rotatably connected to one side of the fixed frame 201.

[0027] Please refer to Figure 2 、 3 4. A slider 305 is fixed on one side of the outer side of the rotating shaft 303, and a circulating curved groove 304 is provided on the other side of the outer side of the rotating shaft 303. When the rotating shaft 303 slides left and right, it drives the connecting plate 306 to slide left and right, and the connecting plate 306 drives the brush column 307 to slide left and right to clean the copper wire 404 and the copper chips on the surface of the second roller 3. The slider 305 is slidably connected to the inside of the slide groove 207. A spray pipe 309 is provided on the top of the piston cylinder 308. A plurality of guide rollers 101 are provided on the top of the fixed plate 1. Copper wire 404 is provided on the outer side of the guide roller 101. When the rotating shaft 303 slides left and right, the piston cylinder 308 is pushed to spray oil from the spray pipe 309 to the second roller 3 On the copper wire 404, the copper wire 404 is lubricated to prevent it from breaking. An oil tank 402 is provided on one side of the piston cylinder 308 inside the fixed plate 1, and a one-way valve 403 is provided on the top of the oil tank 402. The rotating shaft 303 slides left and right. Because the slider 305 outside the rotating shaft 303 is slidingly connected to the slide groove 207, the rotating shaft 303 pulls the piston cylinder 308 when it slides left and right. The piston cylinder 308 sucks out the oil inside the oil tank 402. The other side of the oil tank 402 is connected to the piston cylinder 308. The outer side of the fixed cylinder 206 is rotatably connected to the No. 2 roller 3. The inner wall of the No. 2 roller 3 is fixed with an extrusion column 302, and the extrusion column 302 is slidingly connected to the inside of the circulation curve groove 304.

[0028] In this embodiment, the rotating shaft 303 slides left and right. Because the slider 305 on the outside of the rotating shaft 303 is slidably connected to the slide groove 207, the sliding movement of the rotating shaft 303 pulls the piston cylinder 308, which draws the oil from the oil tank 402. The sliding movement of the rotating shaft 303 pushes the piston cylinder 308, causing the oil to be sprayed from the spray pipe 309 onto the second roller 3 and the copper wire 404, lubricating the copper wire 404 and preventing breakage. The sliding movement of the rotating shaft 303 drives the connecting plate 306 to slide left and right, which drives the brush column 307 to slide left and right, cleaning the copper wire 404 and the surface of the second roller 3.

[0029] Working principle: The copper wire 404 passes through the guide roller 101, the No. 1 roller 202, and the No. 2 roller 3, and the end of the copper wire 404 is connected to the external take-up roller. The copper wire 404 is pulled by the rotation of the take-up roller to move, and the cylinder 4 is started to pull the connecting rod 401 downward. The connecting rod 401 pulls the ends of the No. 1 crank 203 and the No. 2 crank 204, so that the end of the No. 1 crank 203 moves toward the position of the fixed frame 201. The No. 1 crank 203 pulls the No. 2 crank 204 to move toward the position of the fixed frame 201. The No. 2 crank 204 pulls the tension frame 205 toward the position of the fixed frame 201, so that the distance between the No. 2 roller 3 and the No. 1 roller 202 in the tension frame 205 is changed. The distance between the No. 2 roller 3 and the No. 1 roller 202 is mechanically adjusted to prevent tension adjustment fluctuations when adjusting the tension frame.

[0030] The movement of the copper wire 404 drives the contacting roller 3, which in turn rotates the rotating ring 301. The rotating ring 301 squeezes the circular curved groove 304 inside the rotating shaft 303 via the squeezing column 302, causing the rotating shaft 303 to slide left and right. Because the slider 305 outside the rotating shaft 303 is slidably connected to the sliding groove 207, the sliding movement of the rotating shaft 303 pulls the piston cylinder 308, which draws oil from the oil tank 402. The sliding movement of the rotating shaft 303 pushes the piston cylinder 308, causing the oil to be sprayed from the spray pipe 309 onto the roller 3 and the copper wire 404, lubricating the copper wire 404 and preventing breakage. The sliding movement of the rotating shaft 303 drives the connecting plate 306 left and right, which in turn drives the brush column 307 left and right, cleaning copper chips from the copper wire 404 and the surface of the roller 3.
