Description

Technical Field

[0001] This invention relates to the field of polishing and wire drawing machine technology, and in particular to a wire drawing and polishing machine with tension adjustment function. Background Technology

[0002] Wire drawing and polishing, as an important surface treatment process, is widely used in the processing of metal and plastic workpieces to remove surface defects, improve smoothness, or create specific texture effects. In actual production, the size, shape, and processing requirements of workpieces vary, placing higher demands on the adaptability of equipment.

[0003] Chinese patent CN202894950U discloses a grinding and polishing device for a wire drawing machine, including a frame, a polishing wheel, a straightening cylinder, and a polishing motor. The straightening cylinder and polishing motor are mounted on the frame, and the grinding wheel is located below the straightening cylinder. The polishing motor is connected to the polishing wheel via a first pulley, and a lifting device is connected to the polishing wheel and is also connected to the frame. Grinding, wire drawing, and polishing of the steel pipe surface are performed on the same production line, improving overall processing accuracy, significantly reducing production costs, and increasing production efficiency.

[0004] However, the above invention has the following shortcomings: differences in workpiece size and polishing wire drawing path often require the contact area between the polishing wire and the workpiece to be adjusted accordingly. Due to structural limitations, existing equipment cannot flexibly adjust the effective contact area of ​​the polishing wire to suit workpiece characteristics. When the effective contact area increases due to process requirements or workpiece size, the polishing wire may become suspended or poorly adhered in the center of the contact area, resulting in the effective contact surface not fully and evenly adhering to the workpiece surface. This not only reduces polishing efficiency and consistency but may also cause workpiece surface damage or abnormal wear of the polishing wire due to uneven local pressure. Summary of the Invention

A telescopic rod is fixedly connected to each of the two adjacent fixed blocks. A telescopic spring is sleeved on each of the multiple telescopic rods. The two ends of the telescopic spring are fixedly connected to the two adjacent fixed blocks respectively. An L-shaped rod is fixedly connected to the sliding rod. Two rotating rollers are rotatably connected to the bottom of the L-shaped rod. A strip block is fixedly connected to the extrusion roller near the rotating roller. The two rotating rollers are in contact with the two sides of the strip block respectively.

[0007] Preferably, each of the sliding plates is fixedly connected to a motor, and the output ends of the two motors are respectively fixedly connected to the top of the drive roller.

[0008] Preferably, each of the fixed plates is provided with a compression spring, and the two ends of the compression spring are fixedly connected to the fixed plate and the U-shaped slide rod, respectively.

[0009] Preferably, the extrusion unit includes a fixed rod fixedly connected to each sliding plate, a movable rod slidably connected to the fixed rod, a driven roller rotatably connected to the movable rod, a mounting block fixedly connected to one end of the movable rod, a rotating shaft rotatably connected to the mounting block, a fixing strip fixedly connected to the bottom end of the rotating shaft, a strip-shaped hole provided on the fixing strip, a cylindrical rod slidably connected to the U-shaped slide rod, and the top end of the cylindrical rod extending into the strip-shaped hole.

[0012] Preferably, the drive unit includes a second hydraulic cylinder fixedly connected to the fixed frame, the output end of the second hydraulic cylinder fixedly connected to one of the sliding plates, fixed racks fixedly connected to both sliding plates, a fixed column fixedly connected to the top interior of the fixed frame, a rotating gear rotatably connected to the bottom end of the fixed column, and both fixed racks meshing with the rotating gear.

[0013] Preferably, two guide rods are fixedly connected to the fixing frame, and the two sliding plates are slidably connected to the two guide rods.

[0014] Preferably, the conveying assembly has two fixed baffles fixedly connected to it, one end of each fixed baffle is rotatably connected to a rotating plate, a cylindrical block is fixedly connected to each of the two rotating plates, a connecting strip is fixedly connected to each of the two sliding plates, and an elongated hole is opened on each of the connecting strips, with the top ends of the two cylindrical blocks extending into the two elongated holes respectively.

[0015] This invention provides a wire drawing and polishing machine with tension adjustment function, which has the following improvements and advantages compared with the prior art: Firstly, this invention, through the setting of the wire drawing unit, activates the first hydraulic cylinder to drive the sliding rod and rotating roller to move. The movement of the rotating roller can cause the polishing wire drawing strip to elongate, thereby increasing the contact area between the polishing wire drawing strip and the workpiece. The movement of the sliding rod drives the L-shaped rod to move, the movement of the L-shaped rod drives the two rotating wheels to move, and the movement of the two rotating wheels drives the strip block and one of the extrusion wheels to move. Under the combined action of the telescopic rod and the telescopic spring, multiple extrusion wheels can be spread out at equal intervals. As the polishing wire drawing strip elongates, multiple extrusion wheels can uniformly extrude pressure on the contact surface of the polishing wire drawing strip, thereby improving the uniform support and pressing effect of the polishing wire drawing strip, and thus improving the polishing wire drawing effect on the workpiece.

[0016] Secondly, this invention, through the arrangement of the extrusion unit, causes the polishing wire to elongate, driving the driven roller towards the fixed plate. The driven roller then moves the movable rod, mounting block, rotating shaft, and fixing bar. The movement of the fixing bar moves the cylindrical rod, U-shaped slide rod, and multiple extrusion wheels, ensuring that the multiple extrusion wheels fully compress the polishing wire into contact with the workpiece. When the extrusion wheels stop moving, the elongation of the polishing wire causes the driven roller, movable rod, and mounting block to continue moving. The movement of the mounting block drives the rotating shaft and fixing bar to rotate, and the fixing bar drives the torsion spring to rotate and undergo elastic deformation. As the deformation of the torsion spring increases, the pressure of the extrusion wheels on the polishing wire increases, thereby increasing the contact area of ​​the polishing wire and evenly pressing the contact area of ​​the polishing wire onto the workpiece, improving the wire drawing effect. At the same time, the two sets of extrusion wheels can clamp the workpiece, improving its stability.

[0017] Thirdly, this invention, through the setting of the drive unit, activates the second hydraulic cylinder to drive one of the sliding plates to move. The movement of one of the sliding plates drives one of the fixed racks to move. The movement of one of the fixed racks drives another fixed rack and another sliding plate to move through a rotating gear. This allows the two sliding plates to slide closer or further apart simultaneously. The movement of the sliding plates drives the polishing and drawing strips to move, thereby adjusting the spacing between the two polishing and drawing strips according to the width of the workpiece. This enables polishing and drawing of workpieces of different widths. The movement of the sliding plates drives the connecting strip to move, the movement of the connecting strip drives the cylindrical block to move, and the movement of the cylindrical block drives the rotating plate to rotate. The two rotating plates can center the workpiece, realizing the ability to adjust the spacing of the polishing and drawing strips while adaptively adjusting the spacing of the rotating plates.

[0021] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] This invention provides an improved wire drawing and polishing machine with tension adjustment function. The technical solution of this invention is as follows: like Figures 1 to 8 As shown, this embodiment of the invention provides a wire drawing and polishing machine with tension adjustment function, including a frame 1, a fixed frame 11 fixedly connected to the top of the frame 1, a conveying assembly 5 fixedly connected to the top of the fixed frame 11, and further including: The wire drawing mechanism is located on the fixed frame 11; The wire drawing mechanism includes a drive unit, a wire drawing unit, and an extrusion unit. The wire drawing unit includes two sliding plates 13 mounted above the frame 1. A drive roller 15 is rotatably connected to each sliding plate 13. A first hydraulic cylinder 112 is fixedly connected to each sliding plate 13. A sliding rod 16 is slidably connected to each sliding plate 13. The output end of the first hydraulic cylinder 112 is fixedly connected to the sliding rod 16. A rotating roller 17 is rotatably connected to the sliding rod 16. A driven roller 110 is located below the sliding plate 13. The drive roller 15, the rotating roller 17, and the driven roller 110 are all tensioned together. A polishing ribbon 111 is attached to the bottom of the sliding plate 13. A fixing plate 2 is fixedly connected to the bottom of the sliding plate 13. A U-shaped slide rod 21 is slidably connected to the fixing plate 2. Multiple extrusion rollers 22 are provided below the sliding plate 13. One end of the U-shaped slide rod 21 is fixedly connected to the extrusion roller 22 near the drive roller 15. Two fixing blocks 23 are fixedly connected to each of the multiple extrusion rollers 22. A telescopic rod 24 is fixedly connected to two adjacent fixing blocks 23. A telescopic spring 25 is sleeved on each of the multiple telescopic rods 24. The two ends of the telescopic spring 25 are fixedly connected to two adjacent fixing blocks 23 respectively. Next, an L-shaped rod 29 is fixedly connected to the sliding rod 16. Two rotating wheels 28 are rotatably connected to the bottom of the L-shaped rod 29. A strip block 27 is fixedly connected to the extrusion wheel 22 near the rotating roller 17. The two rotating wheels 28 contact the two sides of the strip block 27 respectively. Through the setting of the wire drawing unit, the first hydraulic cylinder 112 is activated to drive the sliding rod 16 and the rotating roller 17 to move. The movement of the rotating roller 17 can drive the polishing wire drawing strip 111 to extend, thereby increasing the contact area between the polishing wire drawing strip 111 and the workpiece, improving the wire drawing effect on the workpiece. The movement of rod 16 drives the movement of L-shaped rod 29, which in turn drives the movement of two rotating wheels 28. The movement of the two rotating wheels 28 drives the movement of strip block 27 and one of the pressing wheels 22. With the cooperation of telescopic rod 24 and telescopic spring 25, the multiple pressing wheels 22 can be spread out at equal intervals. As the polishing and drawing ribbon 111 elongates, the multiple pressing wheels 22 can evenly press the contact surface of the polishing and drawing ribbon 111, thereby improving the uniform support and pressing effect of the polishing and drawing ribbon 111, and thus improving the polishing and drawing effect of the workpiece.

[0023] Furthermore, each sliding plate 13 is fixedly connected to a motor 14, and the output ends of the two motors 14 are respectively fixedly connected to the top of the drive roller 15. Through the setting of the motors 14, the motors 14 drive the drive roller 15 to rotate, and the drive roller 15 drives the polishing and drawing strip 111, the rotating roller 17 and the driven roller 110 to rotate. The rotation of the polishing and drawing strip 111 can polish and draw the workpiece.

[0024] Furthermore, each fixed plate 2 is provided with a compression spring 26, and the two ends of the compression spring 26 are fixedly connected to the fixed plate 2 and the U-shaped slide rod 21 respectively; through the setting of the compression spring 26, the compression spring 26 can drive the U-shaped slide rod 21 to reset.

[0025] Furthermore, the extrusion unit includes a fixed rod 18 fixedly connected to each sliding plate 13, a movable rod 19 slidably connected to the fixed rod 18, a driven roller 110 rotatably connected to the movable rod 19, a mounting block 3 fixedly connected to one end of the movable rod 19, a rotating shaft 31 rotatably connected to the mounting block 3, a fixing strip 32 fixedly connected to the bottom end of the rotating shaft 31, the fixing strip 32 having a strip-shaped hole, a cylindrical rod 34 slidably connected to the U-shaped sliding rod 21, the top end of the cylindrical rod 34 extending into the strip-shaped hole, and a torsion spring 33 sleeved on each rotating shaft 31, the two ends of the torsion spring 33 being fixedly connected to the mounting block 3 and the fixing strip 32 respectively; through the arrangement of the extrusion unit, the polishing tape 111 extends, driving the driven roller 110 to move towards the fixed plate 2, the driven roller 110 drives the movable rod 19 and the mounting block 3 to move, and the movement of the mounting block 3 drives the rotating shaft 31 and the fixed rod 32 to move. The movement of the fixed strip 32 causes the cylindrical rod 34 and the U-shaped slide bar 21 to move. The movement of the U-shaped slide bar 21 causes multiple extrusion rollers 22 to move, so that the multiple extrusion rollers 22 can fully compress the polishing and drawing strip 111 into contact with the workpiece. When the extrusion rollers 22 stop moving, the extension of the polishing and drawing strip 111 causes the driven roller 110, the movable rod 19 and the mounting block 3 to move continuously. The movement of the mounting block 3 causes the rotating shaft 31 and the fixed strip 32 to rotate. The fixed strip 32 causes the torsion spring 33 to rotate and undergo elastic deformation. As the deformation of the torsion spring 33 increases, the pressure of the extrusion rollers 22 on the polishing and drawing strip 111 also increases. This increases the contact area of ​​the polishing and drawing strip while uniformly pressing the contact area of ​​the polishing and drawing strip 111 onto the workpiece, improving the drawing effect on the workpiece. At the same time, the two sets of extrusion rollers 22 can clamp the workpiece, improving the stability of the workpiece.

[0026] Furthermore, a return spring 113 is provided inside the fixed rod 18, and the two ends of the return spring 113 are fixedly connected to the fixed rod 18 and the movable rod 19 respectively; through the setting of the return spring 113, the return spring 113 can drive the movable rod 19, the mounting block 3, the rotating shaft 31 and the fixed bar 32 to reset.

[0027] Furthermore, the drive unit includes a second hydraulic cylinder 4 fixedly connected to the fixed frame 11. The output end of the second hydraulic cylinder 4 is fixedly connected to one of the sliding plates 13. Fixed racks 43 are fixedly connected to both sliding plates 13. A fixed column 41 is fixedly connected inside the top of the fixed frame 11. A rotating gear 42 is rotatably connected to the bottom end of the fixed column 41. Both fixed racks 43 mesh with the rotating gear 42. By setting up the drive unit, starting the second hydraulic cylinder 4 drives one of the sliding plates 13 to move. The movement of one of the sliding plates 13 drives one of the fixed racks 43 to move. The movement of one of the fixed racks 43 drives the other fixed rack 43 and the other sliding plate 13 to move through the rotating gear 42. This allows the two sliding plates 13 to slide closer or further apart at the same time. The movement of the sliding plates 13 drives the polishing wire 111 to move. Thus, the spacing between the two polishing wire 111 can be adjusted according to the width of the workpiece, thereby enabling polishing and wire drawing of workpieces of different widths.

[0028] Furthermore, two guide rods 12 are fixedly connected to the fixed frame 11, and the two sliding plates 13 are slidably connected to the two guide rods 12; the setting of the guide rods 12 improves the stability of the sliding plates 13.

[0029] Furthermore, two fixed baffles 51 are fixedly connected to the conveying assembly 5. A rotating plate 52 is rotatably connected to one end of each fixed baffle 51. A cylindrical block 53 is fixedly connected to each of the two rotating plates 52. A connecting strip 54 is fixedly connected to each of the two sliding plates 13. An elongated hole is opened on each connecting strip 54. The top ends of the two cylindrical blocks 53 extend into the two elongated holes respectively. Through the setting of the conveying assembly 5, the conveying assembly 5 can convey the workpiece. The movement of the sliding plate 13 drives the movement of the connecting strip 54, the movement of the connecting strip 54 drives the movement of the cylindrical block 53, and the movement of the cylindrical block 53 drives the rotation of the rotating plate 52. The two rotating plates 52 can center the workpiece, realizing the adjustment of the spacing of the polishing ribbon 111 while adaptively adjusting the spacing of the rotating plates 52.

[0030] Working principle: Motor 14 drives drive roller 15 to rotate, drive roller 15 drives polishing wire 111, rotating roller 17 and driven roller 110 to rotate. The rotation of polishing wire 111 can polish and draw the workpiece. Start the first hydraulic cylinder 112 to drive sliding rod 16 to move, sliding rod 16 drives rotating roller 17 to move, rotating roller 17 drives polishing wire 111 to extend, polishing wire 111 extends and drives driven roller 110 to move towards fixed plate 2, driven roller 110 drives moving rod 19 to move, moving rod 19 drives return spring 113. The tension and elastic deformation increase the contact area between the polishing wire 111 and the workpiece, improving the wire-drawing effect. The movement of the movable rod 19 moves the mounting block 3, which in turn moves the rotating shaft 31 and the fixing bar 32. The fixing bar 32 moves the cylindrical rod 34, which in turn moves the U-shaped slide bar 21. The U-shaped slide bar 21 then moves multiple extrusion rollers 22, ensuring that the polishing wire 111 fully contacts the workpiece. The movement of the U-shaped slide bar 21 compresses the extrusion spring 26, causing it to undergo elastic deformation. When the extrusion roller 22 stops moving, the extension of the polishing ribbon 111 causes the driven roller 110, the movable rod 19, and the mounting block 3 to move continuously. The movement of the mounting block 3 drives the rotating shaft 31 and the fixing strip 32 to rotate. The fixing strip 32 drives the torsion spring 33 to rotate and undergo elastic deformation. As the deformation of the torsion spring 33 increases, the pressure of the extrusion roller 22 on the polishing ribbon 111 also increases. The movement of the sliding rod 16 drives the L-shaped rod 29 to move. The movement of the L-shaped rod 29 drives the two rotating rollers 28 to move. The movement of the two rotating rollers 28 drives the strip block 27 and one of the extrusion rollers. The movement of the 22-axis, in conjunction with the telescopic rod 24 and the telescopic spring 25, allows multiple extrusion rollers 22 to unfold at equal intervals. As the polishing wire 111 elongates, the multiple extrusion rollers 22 can uniformly extrude the contact surface of the polishing wire 111, thereby improving the uniform support and pressing effect of the polishing wire 111. This increases the contact surface of the polishing wire while uniformly pressing the contact surface of the polishing wire 111 onto the workpiece, improving the wire drawing effect on the workpiece. At the same time, the two sets of extrusion rollers 22 can clamp the workpiece, improving the stability of the workpiece.The conveying assembly 5 can convey the workpiece. Activating the second hydraulic cylinder 4 moves one of the sliding plates 13, which in turn moves one of the fixed racks 43. This movement of the fixed rack 43, through a rotating gear 42, moves the other fixed rack 43 and the other sliding plate 13, allowing the two sliding plates 13 to slide closer or further apart simultaneously. The movement of the sliding plates 13 moves the polishing and brushing ribbons 111, thus adjusting the spacing between the two polishing and brushing ribbons 111 according to the width of the workpiece. This allows for polishing and brushing of workpieces of different widths. The movement of the sliding plates 13 moves the connecting strip 54, which in turn moves the cylindrical block 53. The cylindrical block 53 then rotates the rotating plate 52, allowing the two rotating plates 52 to center the workpiece. This achieves adaptive adjustment of the spacing of the rotating plates 52 while simultaneously adjusting the spacing of the polishing and brushing ribbons 111.
