Traditional devices are usually designed for wires of specific specifications and are difficult to adapt to irregular wires of different shapes and sizes, resulting in poor equipment versatility. During the drawing process, various components of the device may become loose or displaced due to uneven force, affecting the drawing quality and efficiency. The impact force and vibration generated during the drawing process may cause damage to the wire surface or wear on the equipment. The buffer design of traditional devices often cannot meet the requirements of high-precision drawing.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figures 1-5 As shown, a non-standard wire drawing device includes a movable guide rail 1 and a movable base 2, with a drawing adjustment component 3 provided on the top of the movable base 2.

[0027] The pull-out adjustment assembly 3 includes a lower fixed seat 301 set on the top of the movable seat 2. The lower fixed seat 301 is connected to an upper fixed seat 302 by fastening bolts. One end of the lower fixed seat 301 and the upper fixed seat 302 is connected to a limiting member 307. One end of the limiting member 307 that passes through the lower fixed seat 301 and the upper fixed seat 302 is connected to an adjustment frame 306. The inner wall of the adjustment frame 306 is connected to a cross shaft 310. The outer wall of the cross shaft 310 is connected to a universal joint 311. One end of the outer wall of the cross shaft 310 near the inner side of the universal joint 311 is connected to a movable ball 312. Both ends of the movable ball 312 away from the cross shaft 310 are connected to limiting blocks 313. The ends of the two limiting blocks 313 away from the movable ball 312 are connected to rollers 314 by connecting rods. Both ends of the two rollers 314 are connected to moving rods 315.

[0028] The lower fixed seat 301 and the upper fixed seat 302 are both threadedly fixed to the adjusting frame 306 through the limiting member 307. The adjusting frame 306 is threadedly fixed to the universal joint 311 through the cross shaft 310. The cross shaft 310 is threadedly fixed to two limiting blocks 313. The limiting blocks 313 are threadedly fixed to two rollers 314 through the connecting rod. The rollers 314 are rotatably connected to two moving rods 315. The inner sides of the lower fixed seat 301 and the upper fixed seat 302 are provided with adjusting grooves 303. The two adjacent moving rods 315 are slidably connected inside the adjusting grooves 303.

[0029] By rotating the cross shaft 310, combined with the sliding of the limiting block 313 and the roller 314 in the adjusting groove 303, the angle of the positioning rod 308 on the inner side of the upper and lower fixed seats 301 and 302 is finely adjusted so that the guide hole of the positioning rod 308 is precisely aligned with the wire inlet direction of the shaped wire, ensuring a smooth drawing process.

[0030] A positioning rod 308 is connected to the bottom of the adjusting frame 306, and a positioning frame 309 is connected to the bottom of the positioning rod 308. An air spring 318 is connected to the top of the inner side of the positioning frame 309, and an L-shaped fixing plate 319 is connected to the bottom of the air spring 318. A fixing cylinder 320 is connected to one end of the L-shaped fixing plate 319, and a first rounded corner pull plate 321 is connected to the end of the fixing cylinder 320 away from the L-shaped fixing plate 319 via a connecting rod. The inner side of the positioning frame 309 away from the L-shaped fixing plate... One end of 319 is connected to a clamping block 322, and the inner side of the clamping block 322 is engaged with a second rounded corner pull plate 323. One end of the first rounded corner pull plate 321 and the second rounded corner pull plate 323 are both glued with multiple magnetic suction pieces 324; the top of the universal joint 311 is connected to a positioning block 316, the top of the positioning block 316 is connected to a buffer spring 317, the top of the buffer spring 317 is connected to an adjusting block 304, and the top of the adjusting block 304 is threadedly fixedly connected to a locking piece 305;

[0031] The positioning frame 309 is fixedly connected to the air spring 318, and the air spring 318 is fixedly connected to the L-shaped fixing plate 319. The L-shaped fixing plate 319 is connected to the inner side of the positioning frame 309 by fastening bolts. The L-shaped fixing plate 319 is rotatably connected to the fixing cylinder 320. The fixing cylinder 320 is threadedly fixedly connected to the first rounded corner pull plate 321 by a connecting rod. The positioning frame 309 is threadedly fixedly connected to the clamping block 322. The magnetic suction pieces 324 at one end of the first rounded corner pull plate 321 and the second rounded corner pull plate 323 attract each other. The adjusting block 304 is movably connected to the positioning block 316 by a buffer spring 317. The positioning block 316 is threadedly fixedly connected to the top of the universal joint 311 by a mounting rod.

[0032] According to the specifications and shape of the irregular wire to be drawn, a suitable first rounded corner drawing plate 321 and a second rounded corner drawing plate 323 are selected. The surface of the magnetic suction plate 324 is ensured to be clean and the suction force is normal. The first rounded corner drawing plate 321 is connected to the L-shaped fixing plate 319 via the fixing cylinder 320 and the connecting rod. Ensuring a secure threaded connection without loosening, the second rounded corner drawing plate 323 is installed onto the clamping block 322 and then threadedly fixed to the positioning frame 309 via the clamping block 322. Ensure the second rounded corner pull plate 323 is correctly positioned and the magnetic suction piece 324 faces inward. Based on the approximate dimensions of the shaped wire, manually rotate the L-shaped fixing plate 319 to initially adjust the distance between the first rounded corner pull plate 321 and the second rounded corner pull plate 323, making it slightly larger than the dimensions of the shaped wire. By rotating the cross shaft 310, adjust the overall angle of the positioning rod 308 so that it is basically consistent with the wire inlet direction. Insert the shaped wire to be pulled through the inlet and pass it through the positioning rod. The guide hole 308 is placed between the first rounded corner drawing plate 321 and the second rounded corner drawing plate 323. By observation, it is determined whether the shaped wire is centered between the two drawing plates. If it is off-center, it can be coarsely adjusted by finely adjusting the angle of the L-shaped fixing plate 319 or the angle of the positioning rod 308. Continue to rotate the L-shaped fixing plate 319 to bring the first rounded corner drawing plate 321 closer to the second rounded corner drawing plate 323. The magnetic attraction plate 324 is used to firmly clamp the shaped wire. Ensure that the shaped wire is not loose between the two drawing plates and is not deformed due to excessive clamping force.

[0033] When the drawing equipment is started, the moving seat 2 begins to move on the moving guide rail 1, driving the entire drawing adjustment assembly 3 to perform the drawing motion. During the drawing process, the buffer spring 317 and the air spring 318 respectively play a buffering role. The buffer spring 317 is connected between the positioning block 316 and the adjusting block 304, and can absorb the impact caused by slight changes in the size of the irregular wire or fluctuations in the drawing resistance. The air spring 318 is connected between the L-shaped fixing plate 319 and the positioning frame 309, and can provide elastic support for the rotation of the L-shaped fixing plate 319 and absorb the vibration generated during the drawing process, protecting the equipment and the wire. The L-shaped fixing plate 319 is rotated in the opposite direction to increase the distance between the first rounded corner drawing plate 321 and the second rounded corner drawing plate 323, so that the attraction force of the magnetic suction plate 324 disappears, thereby releasing the clamped irregular wire, removing the residue on the first rounded corner drawing plate 321 and the second rounded corner drawing plate 323, and ensuring that the surface of the magnetic suction plate 324 is clean.

[0034] It should be noted that this utility model is a non-standard wire drawing device. In use, the movable seat 2 can move back and forth through the movable guide rail 1 to adapt to wires of different lengths. The lower fixed seat 301 and the upper fixed seat 302 are fixed together by fastening bolts to form a stable frame. The air spring provides elastic buffering, allowing the L-shaped fixed plate to rotate freely within a certain angle range. The rotation of the L-shaped fixed plate will drive the first rounded corner drawing plate to rotate. Multiple magnetic plates 324 are respectively attached to the first rounded corner drawing plate 321 and the second rounded corner drawing plate 323 for clamping non-standard wires during the drawing process. By rotating the cross shaft 310, the universal joint 311 and the movable ball 312 are driven to rotate, thereby changing the overall angle of the positioning rod 308. Since the limiting block 313 is connected to the movable ball 312, the limiting block will also rotate accordingly. By rotating the roller 314, the movable rod 315 can be driven to move back and forth in the adjusting groove 303, thereby fine-tuning the angle of the positioning rod 308 on the inner side of the fixed seat. After adjustment, the wire is drawn back and forth through the roller 314. The adjusting block 304 is locked by the locking member 305 to ensure that the angle of the positioning rod 308 is fixed. The buffer spring 317 is connected between the positioning block 316 and the adjusting block 304 to buffer the angle and prevent it from changing due to impact. By rotating the L-shaped fixing plate 319, the position of the fixing cylinder 320 can be changed, thereby adjusting the angle and position of the first rounded corner pull plate 321. Since the second rounded corner pull plate 323 is fixed on the positioning frame 309, the angle and position of the first rounded corner pull plate 321 can be adjusted by changing the position of the first rounded corner pull plate 321. The distance between the two plates can be adjusted to accommodate irregularly shaped wires of different sizes and shapes. The irregularly shaped wire is placed between the first rounded corner drawing plate 321 and the second rounded corner drawing plate 323. Through the mutual attraction of the magnetic suction piece 324, the irregularly shaped wire is firmly clamped between the two drawing plates, ensuring that the wire will not move or deform during the drawing process. During the drawing process, the buffer spring 317 and the air spring 318 play a buffering role, absorbing the impact force and vibration generated during the drawing process, and protecting the equipment and the wire.
