Description

Technical Field

[0001] This utility model relates to a straightening device, specifically a straightening device for a copper rod, and belongs to the field of copper rod straightening technology. Background Technology

[0002] A copper rod is a rod-shaped product made of pure copper or copper alloys. It has excellent electrical and thermal conductivity, ductility, corrosion resistance, and mechanical properties. A copper rod straightening machine is a device designed to address the bending deformation that may occur in copper rods during processing or use. Its main function is to gradually straighten the bent parts of the copper rod. The working principle of a copper rod straightening machine typically involves the movement of a series of rollers. As the copper rod moves through the machine, it is rolled by a series of rollers in turn, thereby achieving the purpose of adjusting the curvature.

[0003] Current copper rod straightening machines straighten copper rods by directly inserting them between two sets of rollers. The rotation of the rollers straightens the copper rods. To reduce friction between the copper rods and the rollers, lubrication is usually required at the contact points. Currently, lubrication is done by applying lubricant to the rollers with a brush. Applying lubricant one by one is slow and uneven, and it is difficult to control the amount of lubricant applied, which can easily lead to waste. Utility Model Content

[0004] The purpose of this invention is to provide a straightening device for copper rods to solve the above problems. It can apply lubricant evenly to the entire rod when the roller rotates, ensuring smooth conveying of the copper rod to the roller and facilitating straightening.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a straightening device for a copper rod, comprising a base plate, a first rolling mechanism, and a second rolling mechanism. The first rolling mechanism and the second rolling mechanism are mounted opposite to each other on the base plate. A lubrication mechanism is mounted on the base plate, and the lubrication mechanism includes two fixed plates. Two fixed plates are fixedly connected opposite to each other on the base plate. Two pull rods are slidably connected opposite to each other on the two fixed plates. Each of the opposite ends of the two pull rods is fixedly connected to a box that abuts against the surface of the base plate. A sponge pad is placed inside each of the two boxes. The opposite sides of the two sponge pads abut against the first rolling mechanism and the second rolling mechanism, respectively. A rotating ring is rotatably connected to each of the two pull rods. A limit block is fixedly connected to each of the two rotating rings. A vertical groove corresponding to the limit block is formed on each of the two fixed plates. A first spring is clamped between each of the two boxes and the fixed plates.

[0006] Preferably, the lubrication mechanism further includes pressure plates, and pressure plates that abut against the sponge pads are placed on both of the boxes, and the cross-sections of the two sponge pads are both L-shaped.

[0007] Preferably, the lubrication mechanism further includes oil leakage holes, and multiple oil leakage holes are equally spaced on both pressure plates.

[0008] Preferably, the lubrication mechanism further includes slide rods, and two slide rods are fixedly connected to the opposite sides of the two boxes about the pull rod. The two sets of slide rods are slidably connected to the two fixed plates respectively, and the two slide rods are located inside the two sets of first springs respectively.

[0009] Preferably, the first rolling mechanism includes multiple rotating shafts, and multiple rotating shafts are fixedly connected at equal intervals on the base plate. Each of the multiple rotating shafts is rotatably connected to a first roller, and one side of one of the sponge pads abuts against the multiple first rollers.

[0010] Preferably, the second rolling mechanism includes multiple slide rails. The base plate has slide rails equidistantly spaced between two adjacent first rollers. Each of the multiple slide rails has a slider slidably connected inside. Each of the multiple sliders has a second roller rotatably connected to it. Each of the multiple sliders has a lead screw rotatably connected to its side. The lead screw is threaded to the base plate. The end of the lead screw is fixedly connected to a rudder. The top surfaces of the first rollers and the second rollers are on the same plane. The bottom surfaces of the first rollers and the second rollers are on the same plane.

[0011] Preferably, two sets of scraping mechanisms are installed on the base plate. Each scraping mechanism includes two sets of mounting seats. A mounting seat fixed to the base plate is provided between two adjacent first rollers and two adjacent second rollers. A sliding shell is fixedly connected to each of the mounting seats. A scraper is slidably connected to the inside of the sliding shell. A second spring is clamped between two opposing scrapers and the sliding shell. One set of scrapers abuts against the first rollers, and the other set of scrapers abuts against the second rollers.

[0012] Preferably, the end of the scraper has an arc-shaped structure, and the width of the scraper is equal to the inner width of the first roller and the second roller.

[0013] Preferably, two sets of positioning mechanisms are installed on the base plate. The positioning mechanism includes two fixed frames. The base plate is fixedly connected to two fixed frames. The inner side of each of the two fixed frames is provided with two parallel rollers. The inner shafts of the two sets of rollers are rotatably connected to the fixed frames. The ends of the two sets of inner shafts are threadedly connected to nuts that abut against the fixed frames.

[0014] The beneficial effects of this utility model are as follows: When the first rolling mechanism and the second rolling mechanism need to be lubricated, lubricating oil is poured into the inside of the box, and the sponge pad absorbs the lubricating oil. The limiting block on the rotating ring is rotated to align the limiting block with the slide groove. At this time, the first spring opens and pushes the two boxes toward the first rolling mechanism and the second rolling mechanism. The two sponge pads respectively abut against the sides of the first rolling mechanism and the second rolling mechanism. The pressing plate squeezes the sponge pads, which helps the lubricating oil to be absorbed to the ends of the sponge pads. As the first rolling mechanism and the second rolling mechanism roll, they rub against the sponge pads, thus lubricating both of them. This reduces the friction between the first rolling mechanism and the second rolling mechanism and the copper rod, making the movement of the copper rod smoother when straightening.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6 As shown, a straightening device for a copper rod includes a base plate 1, a first rolling mechanism 2, and a second rolling mechanism 4. The first rolling mechanism 2 and the second rolling mechanism 4 are mounted opposite each other on the base plate 1. A lubrication mechanism 5 is mounted on the base plate 1. The lubrication mechanism 5 includes two fixed plates 502, which are fixedly connected to the base plate 1. Two pull rods 507 are slidably connected to the two fixed plates 502. The opposite ends of the two pull rods 507 are fixedly connected to a contact point that abuts against the surface of the base plate 1. The two boxes 501 each contain a sponge pad 504 inside. The opposite sides of the two sponge pads 504 respectively abut against the first rolling mechanism 2 and the second rolling mechanism 4. The two pull rods 507 each have a rotating ring 508 rotatably connected to them. The two rotating rings 508 each have a fixed limit block 509 fixedly connected to them. The two fixing plates 502 each have a vertically opened groove 510 corresponding to the limit block 509. The two boxes 501 and the fixing plates 502 each have a first spring 506 clamped between them.

[0024] As a technical optimization of this utility model, the lubrication mechanism 5 further includes a pressure plate 503. Each of the two boxes 501 has a pressure plate 503 that abuts against the sponge pad 504. The cross-section of each of the two sponge pads 504 is L-shaped, which facilitates squeezing the lubricating oil inside the box 501 into the end of the sponge pad 504. The lubrication mechanism 5 also includes an oil leakage hole 511. Multiple oil leakage holes 511 are equally spaced on each of the two pressure plates 503, which facilitates adding lubricating oil to the sponge pad 504.

[0025] As a technical optimization of this utility model, the lubrication mechanism 5 further includes slide rods 505. Two slide rods 505 are fixedly connected to the opposite sides of the two boxes 501 about the pull rod 507. The two sets of slide rods 505 are slidably connected to the two fixed plates 502 respectively. The two slide rods 505 are located inside the two sets of first springs 506 respectively, which increases the stability of the box 501 when it moves.

[0026] As a technical optimization of this utility model, the first rolling mechanism 2 includes multiple rotating shafts 201, and multiple rotating shafts 201 are fixedly connected at equal intervals on the base plate 1. First rollers 202 are rotatably connected to each of the multiple rotating shafts 201, and one side of one of the sponge pads 504 abuts against the multiple first rollers 202. The second rolling mechanism 4 includes multiple slide rails 403, and slide rails 403 are equally spaced on the base plate 1 between adjacent first rollers 202. Sliding sliders 404 are slidably connected inside each of the multiple slide rails 403. Each of the multiple sliders 404 is rotatably connected to a second roller 401, and each of the multiple sliders 404 is rotatably connected to a lead screw 405 on its side. The lead screw 405 is threadedly connected to the base plate 1, and a rudder disk 402 is fixedly connected to the end of the lead screw 405. The top surfaces of the first roller 202 and the second roller 401 are located on the same plane, and the bottom surfaces of the first roller 202 and the second roller 401 are located on the same plane. A copper rod is inserted between the first roller 202 and the second roller 401, and the copper rod is straightened as the two rollers roll.

[0027] As a technical optimization of this utility model, two sets of scraping mechanisms 6 are installed on the base plate 1. Each scraping mechanism 6 includes two sets of mounting seats 603. Mounting seats 603 fixed to the base plate 1 are provided between two adjacent first rollers 202 and two adjacent second rollers 401. Sliding housings 601 are fixedly connected to each of the mounting seats 603. Scraper blades 602 are slidably connected to the inside of each sliding housing 601. Each pair of opposing scraper blades 602 is clamped between itself and the sliding housing 601. The second spring 604 has one set of scrapers 602 that abut against the first roller 202, and another set of scrapers 602 that abut against the second roller 401. The ends of the scrapers 602 are arc-shaped, and the width of the scrapers 602 is equal to the inner width of the first roller 202 and the second roller 401. As the first roller 202 and the second roller 401 rotate, the scrapers 602 scrape away the debris on the sides of the first roller 202 and the second roller 401, preventing the copper rod from being dented when it is crushed.

[0028] As a technical optimization of this utility model, two sets of positioning mechanisms 3 are installed on the base plate 1. The positioning mechanism 3 includes two fixed frames 301. The base plate 1 is fixedly connected to two fixed frames 301. The inner side of each of the two fixed frames 301 is provided with two parallel rollers 302. The inner shafts 303 that pass through the fixed frames 301 are rotatably connected to the inside of each of the two sets of rollers 302. The ends of the two sets of inner shafts 303 are threadedly connected to nuts 304 that abut against the fixed frames 301. This achieves the limitation of the copper rod when it enters and exits, and avoids deviation.

[0029] In use, the base plate 1 is installed on the workbench. The copper rod to be straightened is passed between two rollers 302 to achieve initial positioning and prevent deviation. Then, the copper rod is inserted between the first roller 202 and the second roller 401. As the copper rod contacts the first roller 202 and the second roller 401, they roll, and the rolling motion of the first roller 202 and the second roller 401 straightens the copper rod. The straightened copper rod then passes through two rollers 302 in another set, completing the straightening process. The rotatable rudder 402 causes the lead screw 405 to move the slider 404 within the slide rail 403, thereby adjusting the distance between the second roller 401 and the first roller 202. This allows for adjustments to different distances. The diameter of the copper rod is straightened, and the distance between the two rollers 302 is adjusted by turning the nut 304 to complete the adjustment of the distance between the two rollers 302 in the same set; then, when the first roller 202 and the second roller 401 roll, the scraper 602 located inside the sliding housing 601 always abuts against the two adjacent first rollers 202 and second rollers 401, so as to scrape away the debris on the side walls of the first rollers 202 and second rollers 401, and avoid the copper rod from being crushed by contact with debris, which would cause dents and affect the integrity of the copper rod. The second spring 604 can buffer the scraper 602 to avoid excessive resistance and wear on the scraper 602, the first rollers 202 and the second rollers 401; finally, the first roller 202... When the first roller 202 and the second roller 401 do not require lubrication, the pull rod 507 can be pulled to move the box body 501 towards the fixed plate 502. The first spring 506 contracts, and the limiting block 509 on the rotating ring 508 passes over the slide groove 510 on the fixed plate 502, rotating the limiting block 509 by ninety degrees. This achieves the limiting block 509 limiting the pull rod 507, preventing the box body 501 from returning to its original position. Furthermore, the box body 501 causes the sponge pad 504 to move away from the first roller 202 and the second roller 401. Since the sponge pad 504 is no longer in contact with the first roller 202 and the second roller 401, it cannot provide lubrication, reducing the rotational resistance of the first roller 202 and the second roller 401. When lubrication of the first roller 202 and the second roller 401 is required, lubricating oil can be poured into the box. Inside body 501, sponge pad 504 absorbs lubricating oil. Rotating the limiting block 509 on the rotating ring 508 aligns the limiting block 509 with the slide groove 510. At this time, the first spring 506 opens and pushes the two boxes 501 toward the first roller 202 and the second roller 401. The two sponge pads 504 respectively abut against the sides of the first roller 202 and the second roller 401. Pressing the pressure plate 503 squeezes the sponge pads 504, which helps the lubricating oil to be absorbed to the ends of the sponge pads 504. As the first roller 202 and the second roller 401 roll, they rub against the sponge pads 504, thus lubricating them and reducing the friction between the first roller 202 and the second roller 401 and the copper rod, making the movement of the copper rod smoother when straightening.
