Description

Technical Field

[0001] This utility model relates to the field of metal wire processing technology, specifically a metal wire drawing and forming device. Background Technology

[0002] Metal wire drawing is a metal plastic processing process in which wire rod or wire blank is pulled out from the die hole of a drawing die under the action of drawing force to produce small cross-section steel wire or non-ferrous metal wire. Various metals and alloys with different cross-sectional shapes and sizes can be produced by drawing. The drawn wires are dimensionally accurate and have a smooth surface. Moreover, the drawing equipment and dies used are simple and easy to manufacture.

[0003] Currently, in the wire drawing process, when the diameter of the wire is changed, the wire is pulled out by the hole wall as it passes through the die, resulting in a large number of wire lines. This leads to poor appearance of the finished wire, and the uneven surface is more susceptible to oxidation by air. Utility Model Content

[0030] Preferably, the two grinding wheels with rotating parts are arranged in a mirror-symmetrical manner.

[0031] This invention provides a metal wire drawing and forming device. It has the following beneficial effects:

[0032] This invention, by starting a drive motor, drives the first and second take-up and take-up rollers at both ends to rotate, thereby driving the metal wire to be processed to pass around each metal wire auxiliary roller shaft, through a high-frequency heating coil, and through a wire drawing diameter adjustment component. After passing under a cooling nozzle, the metal wire is first heated and softened by the high-frequency heating coil, then thinned by the wire drawing diameter adjustment component, and then cooled by the cooling nozzle. After the metal wire is thinned, it enters the wire drawing bright surface component for bright surface polishing, which removes the vertical lines that appear on the surface when it is thinned, making the surface bright, improving the product appearance, reducing the surface contact area with air, and reducing the oxidation area. Compared with existing metal wire drawing equipment, it has positive effects.

[0033] The first transmission turntable at the front end of the output shaft is driven by a drive motor to rotate. The first transmission belt drives the internal working of the wire drawing bright surface component. The second transmission belt drives the second transmission turntable, thereby linking the rotation of the take-up and release roller drive shaft. The differential locks at both ends of the transmission shaft control the rotation and the right-angle transmission box changes the driving direction, causing the first take-up and release roller and the second take-up and release roller at the upper end to rotate, thereby driving the metal wire to move.

[0034] In this system, rotating the adjustment knob in the wire drawing diameter adjustment assembly causes the coaxial gear in the limiting assembly to rotate in conjunction with the rotating shaft of the wire drawing roller. Since the coaxial gear and the limiting gear ring are interlocked, but the limiting gear ring cannot rotate, the coaxial gear, in order to rotate and break free from the interlocking clamping of the limiting gear ring, uses the force of the two adjacent contacting tooth inclined surfaces to rotate and interlock, pushing the limiting slide at the rear end to push the limiting spring, causing the limiting slide to slide. When the sliding reaches the point where the teeth disengage from each other's tooth grooves, the coaxial gear rotates, thereby enabling the first and second synchronous gears to mesh and rotate synchronously, allowing the two wire drawing rollers to adjust synchronously. By using the different diameters of the connecting wire drawing grooves, the finished diameter of the drawn metal wire can be adjusted and changed. Compared with existing metal wire drawing equipment, this system has the advantage of convenient adjustment.

[0035] The process involves rotating the material threading fixing bolt to allow the material threading lever to slide within the material threading lever groove, thus opening the polishing abrasive wheel belt. Once the metal wire has passed through the two metal tensioning inlets, the material threading lever is reset, and the material threading fixing bolt is rotated to fix its position. Then, the mounting base fixing bolt is rotated to allow the tightening support rod mounting base to slide within the abrasive wheel belt tightening groove, tightening the polishing abrasive wheel belt until it contacts the surface of the metal wire. The mounting base fixing bolt is then rotated to fix the tightening support rod mounting base in its current position. Subsequently, one of the rotating disks is driven to rotate via the first transmission belt, and the two rotating disks are synchronized via the synchronous drive rod. Since the rotating components of the two abrasive wheel belts are mirror-symmetrical, the contact surfaces between the two polishing abrasive wheel belts and the metal wire are also symmetrical.

[0051] 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.

[0052] like Figures 1 to 3As shown, this utility model embodiment provides a metal wire drawing and forming device, including a worktable 1. A first take-up and release roller 2 and a second take-up and release roller 3 are rotatably mounted at both ends of the upper surface of the worktable 1. An integrated mounting frame 4 is fixedly mounted on the upper surface of the worktable 1. A wire drawing diameter adjustment component 5 is fixedly mounted on the upper end of the worktable 1 and below the integrated mounting frame 4. A wire drawing bright surface component 6 is fixedly mounted on the upper end of the worktable 1 and on one side of the integrated mounting frame 4. Metal wire auxiliary rollers 9 are fixedly mounted on the upper end of the worktable 1 and the end of the integrated mounting frame 4 near the first take-up and release roller 2, between the integrated mounting frame 4 and the wire drawing bright surface component 6, and on both the wire drawing bright surface component 6 and the second take-up and release roller 3. A high-frequency heating coil 16 is fixedly mounted on the lower end of the integrated mounting frame 4 and on the side of the integrated mounting frame 4 near the first take-up and release roller 2. A cooling nozzle 15 is fixedly mounted on the lower end of the integrated mounting frame 4 and on the other side of the integrated mounting frame 4.

[0053] Through the above technical solution, this utility model, by starting the drive motor 7, drives the first take-up and release rollers 2 and the second take-up and release rollers 3 at both ends to rotate, thereby driving the metal wire to be processed to pass around each metal wire auxiliary roller 9, through the high-frequency heating coil 16, the wire drawing diameter adjustment component 5, and below the cooling nozzle 15. First, the passing metal wire is heated and softened by the high-frequency heating coil 16, then thinned by the wire drawing diameter adjustment component 5, and then cooled by the cooling nozzle 15. After the metal wire is thinned, it enters the wire drawing bright surface component 6 for bright surface polishing, which removes the vertical lines that appear on the surface when it is thinned, making the surface bright, improving the product appearance, reducing the surface contact area with air, and reducing the oxidation area. Compared with existing metal wire drawing equipment, it has positive effects.

[0054] like Figure 4As shown, a drive motor 7 is fixedly installed on the upper surface of the workbench 1, located on one side of the brushed bright finish component 6. A transmission mounting plate 8 is fixedly installed on the side of the workbench 1. A first transmission turntable 10 and a second transmission turntable 11 are rotatably mounted on the side of the transmission mounting plate 8 away from the drive motor 7, respectively, from top to bottom. The rear end of the first transmission turntable 10 is coaxially connected to the output shaft of the drive motor 7. A second transmission belt 13 is rotatably sleeved on the first transmission turntable 10 and the second transmission turntable 11. Two take-up and release roller drive shaft mounting brackets 17 are fixedly installed on the lower surface of the workbench 1. The two take-up and release rollers... A take-up and release roller drive shaft 18 is rotatably mounted on the drive shaft mounting bracket 17. A third rotating turntable 19 is integrally and coaxially mounted on the take-up and release roller drive shaft 18. A third transmission belt 14 is rotatably sleeved on the second transmission turntable 11 and the third rotating turntable 19. A transmission shaft differential lock 20 is provided at both ends of the take-up and release roller drive shaft 18 and on the lower surface of the worktable 1. A right-angle transmission box 21 is provided at both ends of the take-up and release roller drive shaft 18 and on the lower surface of the worktable 1. The upper output shafts of the two right-angle transmission boxes 21 are coaxially connected to the lower rotating shafts of the first take-up and release roller 2 and the second take-up and release roller 3, respectively.

[0055] Through the above technical solution, the first transmission turntable 10 at the front end of the output shaft is driven by the drive motor 7 to rotate. The first transmission belt 12 drives the internal working of the wire drawing bright surface assembly 6. The second transmission belt 13 drives the second transmission turntable 11, thereby linking the rotation of the take-up and release roller drive shaft 18. The differential lock 20 at both ends of the transmission shaft controls the rotation, and the right angle transmission box 21 changes the driving direction, causing the first take-up and release roller 2 and the second take-up and release roller 3 at the upper end to rotate, thereby driving the metal wire to move.

[0056] like Figure 1 , Figures 5 to 6 As shown, the wire drawing diameter adjustment assembly 5 includes: a wire drawing roller mounting bracket 501, a wire drawing roller rotating shaft 502, a wire drawing roller 503, a wire drawing groove 504, an adjustment knob 505, and an adjustment limit assembly 506; two wire drawing roller rotating shafts 502 are rotatably mounted between the two wire drawing roller mounting brackets 501, and wire drawing rollers 503 are fixedly mounted on both wire drawing roller rotating shafts 502, and several wire drawing grooves 504 are opened on both wire drawing rollers 503; an adjustment knob 505 is coaxially fixedly mounted on one end of the upper wire drawing roller rotating shaft 502 and located outside the wire drawing roller mounting bracket 501, and an adjustment limit assembly 506 is provided on the other end of the upper wire drawing roller rotating shaft 502 and located outside the other wire drawing roller mounting bracket 501; the diameter of the wire drawing groove 504 changes linearly from one cross-section to another on the side of the wire drawing roller 503.

[0057] like Figure 5 , Figures 7 to 9 As shown, the adjusting limiting assembly 506 includes: a limiting assembly outer plate 5061, a first synchronous gear 5062, a second synchronous gear 5063, an elastic gear housing 5064, a coaxial gear 5065, a limiting gear sliding table 5066, a limiting gear sliding groove 5067, a limiting sliding cylinder 5068, a limiting flange 5069, a limiting gear ring 50610, and a limiting spring 50611; the first synchronous gear 5062 and the second synchronous gear 5063 are rotatably mounted on one side surface of the limiting assembly outer plate 5061 from top to bottom, and the elastic gear housing 5064 is fixedly mounted on the other side of the limiting assembly outer plate 5061; the outer end surface of the inner wall of the elastic gear housing 5064... A limiting gear sliding table 5066 is fixedly installed on the surface. A limiting gear sliding groove 5067 is opened on the side of the limiting gear sliding table 5066. A limiting slide cylinder 5068 is slidably sleeved on the limiting gear sliding table 5066. A plurality of limiting flanges 5069 are integrally provided on the inner wall of the limiting slide cylinder 5068. A limiting gear ring 50610 is fixedly installed at the front end of the limiting slide cylinder 5068. A coaxial gear 5065 is coaxially fixedly installed at the rear end of the first synchronous gear 5062. A limiting spring 50611 is provided between the limiting slide cylinder 5068 and the inner wall of the elastic gear housing 5064. The teeth of the coaxial gear 5065 and the limiting gear ring 50610 are staggered.

[0058] Through the above technical solution, by rotating the adjustment knob 505 in the wire drawing diameter adjustment assembly 5, the coaxial gear 5065 in the limiting assembly 506 is rotated in conjunction with the rotating shaft 502 of the wire drawing roller. Since the coaxial gear 5065 and the limiting gear ring 50610 are interlocked, but the limiting gear ring 50610 cannot rotate, the coaxial gear 5065 wants to rotate to get rid of the interlocking and clamping of the limiting gear ring 50610. It uses the force of the two adjacent contacting tooth inclined surfaces to rotate and interlock, pushing the limiting slide at the rear end. The cylinder 5068 pushes the limiting spring 50611, causing the limiting cylinder 5068 to slide. When it slides until the teeth disengage from each other's tooth grooves, the coaxial gear 5065 rotates, thereby causing the first synchronous gear 5062 and the second synchronous gear 5063 to mesh and rotate synchronously, so that the two wire drawing rollers 503 can be adjusted synchronously. By using the different diameters of the through grooves of the connecting wire drawing groove 504, the diameter of the finished metal wire can be adjusted and changed. Compared with existing metal wire drawing equipment, it has the advantage of convenient adjustment.

[0059] like Figure 1 , Figures 10 to 11As shown, the brushed bright finish assembly 6 includes: a bright finish assembly housing 601, a grinding wheel belt rotating component 602, a synchronous drive rod 603, and a first drive belt limiting roller 604; the grinding wheel belt rotating component 602 is rotatably mounted on both sides of the bright finish assembly housing 601, and a plurality of synchronous drive rods 603 are fixedly connected between the two grinding wheel belt rotating components 602; the first drive belt limiting roller 604 is rotatably mounted on the inner wall of one side of the bright finish assembly housing 601 and located on one side of the grinding wheel belt rotating component 602; the grinding wheel belt rotating component 602 and the first transmission turntable 10 are rotatably sleeved with a first transmission belt 12 around the first drive belt limiting roller 604.

[0060] like Figure 10 , Figures 12 to 14 As shown, the grinding wheel belt rotating component 602 includes: a rotating disk 6021, a metal tensioning inlet hole 6022, a material feeding lever groove 6023, a grinding wheel belt tightening groove 6024, a fixed grinding wheel belt support rod 6025, a material feeding lever 6026, a material feeding fixing bolt 6027, a tightening support rod mounting base 6028, a mounting base fixing bolt 6029, a tightening support rod 60210, and a polishing grinding wheel belt 60211; the rotating disk 6021 has a metal tensioning inlet hole 6022 in the middle, and a semi-arc-shaped material feeding lever groove 6023 is formed on the rotating disk 6021 and on one side of the metal tensioning inlet hole 6022; the rotating disk 6021 has a grinding wheel belt tightening groove 6024; a material feeding lever 6026 is slidably disposed in the material feeding lever groove 6023, and the material feeding lever 6026... A material-passing fixing bolt 6027 is provided inside the outer end of 026. A tightening support rod mounting seat 6028 is slidably provided inside the tightening groove 6024 of the grinding wheel belt. A mounting seat fixing bolt 6029 is provided inside the outer end of the tightening support rod mounting seat 6028. A tightening support rod 60210 is fixedly installed inside the tightening support rod mounting seat 6028. Two fixed grinding wheel belt support rods 6025 are fixedly installed inside the rotating disk 6021. The two fixed grinding wheel belt support rods 6025 and the tightening support rod 60210 are distributed in three equal parts from the center. A polishing grinding wheel belt 60211 is rotatably sleeved on the two fixed grinding wheel belt support rods 6025 and the tightening support rod 60210, passing around the material-passing lever 6026. The two grinding wheel belt rotating parts 602 are arranged in a mirror symmetry.

[0061] Through the above technical solution, by rotating the material-feeding fixing bolt 6027, the material-feeding lever 6026 slides within the material-feeding lever groove 6023, disengaging the polishing abrasive wheel belt 60211. When the metal wire passes through the two metal tensioning inlets 6022, the material-feeding lever 6026 is reset, the material-feeding fixing bolt 6027 is rotated to fix its position, and then the mounting base fixing bolt 6029 is rotated to allow the tightening support rod mounting base 6028 to slide within the abrasive wheel belt tightening groove 6024, tightening the polishing abrasive. The wheel belt 60211 brings the polishing wheel belt 60211 into contact with the surface of the metal wire. The rotating mounting base fixing bolt 6029 fixes the tightening support rod mounting base 6028 in the current position. Then, one of the rotating disks 6021 is driven to rotate through the first transmission belt 12, and the two rotating disks 6021 are synchronized through the synchronous drive rod 603. Since the two grinding wheel belt rotating parts 602 are mirror symmetrical, the surfaces of the two polishing wheel belts 60211 in contact with the metal wire are also symmetrical.

[0062] Working principle:

[0063] This invention, by starting the drive motor 7, drives the first take-up and release rollers 2 and the second take-up and release rollers 3 at both ends to rotate, thereby driving the metal wire to be processed to pass around each metal wire auxiliary roller 9, through the high-frequency heating coil 16 and the wire drawing diameter adjustment component 5, and below the cooling nozzle 15. First, the passing metal wire is heated and softened by the high-frequency heating coil 16, then thinned by the wire drawing diameter adjustment component 5, and then cooled by the cooling nozzle 15. After the metal wire is thinned, it enters the wire drawing bright surface component 6 for bright surface polishing, which polishes away the vertical lines that appeared when the wire was thinned, making the surface bright, improving the product appearance, reducing the surface contact area with air, and reducing the oxidation area. Compared with existing metal wire drawing equipment, this invention has positive effects.

[0064] The first transmission turntable 10 at the front end of the output shaft is driven by the drive motor 7 to rotate. The first transmission belt 12 drives the internal working of the wire drawing bright surface assembly 6. The second transmission belt 13 drives the second transmission turntable 11, thereby linking the rotation of the take-up and release roller drive shaft 18. The drive direction is controlled by the differential lock 20 at both ends of the transmission shaft and changed by the right angle transmission box 21, so that the first take-up and release roller 2 and the second take-up and release roller 3 at the upper end rotate, thereby driving the metal wire to move.

[0065] In this process, rotating the adjustment knob 505 in the wire drawing diameter adjustment assembly 5 causes the coaxial gear 5065 in the limiting assembly 506 to rotate in conjunction with the rotating shaft 502 of the wire drawing roller. Since the coaxial gear 5065 and the limiting gear ring 50610 are interlocked, but the limiting gear ring 50610 cannot rotate, the coaxial gear 5065, in order to rotate and break free from the interlocking clamping of the limiting gear ring 50610, uses the force of two adjacent contacting tooth inclined surfaces to rotate and interlock, thus pushing the limiting slide cylinder 506 at the rear end. 8. Push the limit spring 50611 to make the limit slide cylinder 5068 slide. When it slides until the teeth disengage from each other, the coaxial gear 5065 rotates. This causes the first synchronous gear 5062 and the second synchronous gear 5063 to mesh and rotate synchronously, so that the two wire drawing rollers 503 can be adjusted synchronously. By using the different diameters of the through grooves of the wire drawing groove 504, the diameter of the finished metal wire can be adjusted and changed. Compared with the existing metal wire drawing equipment, it has the advantage of convenient adjustment.

[0066] Specifically, by rotating the material-threading fixing bolt 6027, the material-threading lever 6026 slides within the material-threading lever groove 6023, disengaging the polishing abrasive wheel belt 60211. When the metal wire passes through the two metal tensioning inlets 6022, the material-threading lever 6026 is reset, the material-threading fixing bolt 6027 is rotated to fix its position, and then the mounting base fixing bolt 6029 is rotated to allow the tightening support rod mounting base 6028 to slide within the abrasive wheel belt tightening groove 6024, tightening the polishing abrasive wheel belt 60211. 211, make the polishing wheel belt 60211 contact the surface of the metal wire, rotate the mounting base fixing bolt 6029 to fix the tightening support rod mounting base 6028 in the current position, and then drive one of the rotating disks 6021 to rotate through the first transmission belt 12, and then synchronize the two rotating disks 6021 through the synchronous drive rod 603. Since the two grinding wheel belt rotating parts 602 are mirror symmetrical, the surfaces of the two polishing wheel belts 60211 in contact with the metal wire are also symmetrical.
