Description

Technical Field

[0001] The invention relates to the technical field of wire drawing machine equipment, and in particular to a wire drawing machine used for producing ultra-fine copper wires. Background Art

[0002] Wire drawing machines are widely used in machinery manufacturing, hardware processing, petrochemical, plastics, bamboo and wood products, wire and cable and other industries. They are important equipment for copper wire production. The aperture size of the wire drawing die, its core component, directly determines the diameter of a single copper wire. By finely adjusting the aperture of the wire drawing die, copper wire products of different diameters can be obtained.

[0003] A Chinese patent discloses a multi-mode hot wire drawing machine, the publication number is: CN117244954B, and the technical solution disclosed in the patent document is as follows: it includes a machine body, a rotating wheel component, a heating component, a lubricating component and a mold component; the rotating wheel component includes a passive wheel and a driving wheel rotatably connected to the machine body, the passive wheel includes a plurality of wheel bodies with the same outer diameter and each wheel body can rotate relatively independently, the driving wheel is a three-stage tower wheel and each stage of the tower wheel body is independently controlled by a motor, and each stage of the tower wheel body is provided with 2 to 4 metal wire mold tracks; the mold component includes a mounting mold frame and a wire drawing die arranged between the heating box and the driving wheel.

[0004] In order to solve the problem of easy wire breakage in the existing structure, the existing technology is to subject the metal wire on the tower wheel body to different pulling forces and reduce the wire taking-up speed of the take-up wheel body to reduce the wire breakage rate. However, since the position of the wire drawing die in the wire drawing machine is fixed, the diameter of the metal wire will decrease after passing through the wire drawing die. During this process, the metal wire inlet end of the wire drawing die will exert a large force on the metal wire. When producing ultra-fine copper wire, wire breakage will still occur. For this reason, we propose a wire drawing machine for the production of ultra-fine copper wire. Summary of the invention

DETAILED DESCRIPTION

[0041] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] See attached Figure 1-10, a wire drawing machine for producing ultra-fine copper wires, comprising a machine body 1, on which an unwinding drum 2, a driving wheel 5 and a winding drum 6 are arranged, a passive wheel assembly 3 and a die assembly 4 are arranged between the unwinding drum 2 and the driving wheel 5, the unwinding drum 2, the passive wheel assembly 3, the die assembly 4, the driving wheel 5 and the winding drum 6 are arranged on the front of the machine body 1 from left to right in sequence, the copper wire reel is installed on the unwinding drum 2, and then the copper wire is wound around the copper wire wire die path of the passive wheel assembly 3, and then passed through the wire drawing die of the die assembly 4, and finally wound around the copper wire wire die path of the driving wheel 5, and then passed through the wire drawing die of the die assembly 4 again and wound around the copper wire wire die path of the passive wheel assembly 3, after repeating the above winding action to a suitable number of times, the end of the copper wire is fixed to the surface of the winding drum 6, the winding drum 6 winds up the copper wire, and the copper wire passes through several wire drawing dies in sequence to be thinned to a desired diameter;

[0043] The die assembly 4 includes a support plate 41 arranged on the front of the body 1, and a slide groove 42 adapted to the number of copper wire dies is opened on the support plate 41. A slider 43 carrying the wire drawing die is slidably connected in the slide groove 42. One side of the slider 43 is connected to the inner wall of the slide groove 42 through a decompression spring 44. A plurality of adapted wire drawing dies are installed on the slider 43. During the copper wire drawing process, when the copper wire is subjected to excessive tension, the wire drawing die and the slider 43 will be driven to move along the slide groove 42. At this time, a plurality of decompression springs 44 are compressed, and decompression is performed in turn to avoid excessive tension on the copper wire during the ultra-fine copper wire drawing process, resulting in breakage.

[0044] When the copper wire returns to normal after being subjected to tension, the slider 43 and the wire drawing die are reset under the action of the decompression spring 44, so as to facilitate the next decompression.

[0045] In this embodiment, the passive wheel assembly 3 includes a dynamic passive wheel 32 and a fixed passive wheel 33. Before wire drawing, the copper wire on the copper wire reel is first wound around the bottom of the copper wire mold path of the dynamic passive wheel 32, and then passed through the wire drawing die and wound backward to the copper wire mold path of the active wheel 5, and then wound to the copper wire mold path of the fixed passive wheel 33 after passing through the wire drawing die. After winding for a suitable number of times, the end of the copper wire is fixed to the outer wall of the winding drum 6;

[0046] The moving and driven wheels 32 are rotatably connected to the machine body 1, and the axle of the fixed and driven wheels 33 passes through the moving and driven wheels 32 and is connected to the machine body 1, and the wheel portion is arranged on the side of the moving and driven wheels 32 away from the machine body 1. When the copper wire is subjected to excessive tension, the wire drawing die and the slider 43 move along the slide groove 42. At this time, the copper wire follows the movement of the slider 43 and will move away from the moving and driven wheels 32. At this time, the moving and driven wheels 32 can rotate counterclockwise to feed the wire, and the copper wire on the copper wire reel is pulled to unwind, thereby preventing the copper wire between the copper wire reel and the slider 43 from being subjected to a large tension and breaking.

[0047] In this embodiment, a through groove 45 penetrating the bottom of the support plate 41 is provided at the bottom of the slide groove 42 near one side of the body 1, and a connecting block 46 connected to the bottom of the slider 43 is slidably connected in the through groove 45, and a gear rod 47 is connected to the bottom of the connecting block 46. When the copper wire is subjected to excessive tension, the wire drawing die and the slider 43 move along the slide groove 42, and the gear rod 47 is driven to move to the right through the connecting block 46;

[0048] A ratchet unit cooperating with the toothed rod 47 is provided on the moving and driven wheels 32. The toothed rod 47 moves to the right, which drives the moving and driven wheels 32 to rotate counterclockwise through the ratchet unit to feed the wire, thereby preventing the copper wire between the copper wire reel and the slider 43 from being broken by a large tensile force.

[0049] When the toothed rod 47 of the ratchet unit is reset to the left, the moving driven wheel 32 will not rotate. At this time, the copper wire between the copper wire reel and the slider 43 will not be subjected to tension and will not break.

[0050] In this embodiment, the ratchet unit includes a ratchet gear 31 rotatably connected to the front of the body 1, and an inner ratchet 311 is provided inside the ratchet gear 31. The rightward movement of the gear rod 47 drives the ratchet gear 31 to rotate counterclockwise.

[0051] The ratchet unit also includes a plurality of ratchet teeth 322 for matching with the inner ratchet teeth 311. The plurality of ratchet teeth 322 are circumferentially arranged on the side of the moving and driven wheels 32 and are rotatably connected thereto. One side of the ratchet teeth 322 is connected to the side wall of the moving and driven wheels 32 through a support spring 323. When the ratchet gear 31 rotates counterclockwise, the inner ratchet teeth 311 inside it push the ratchet teeth 322, further causing the moving and driven wheels 32 to rotate counterclockwise. The moving and driven wheels 32 rotate counterclockwise to feed the wire, thereby preventing the copper wire between the copper wire reel and the slider 43 from being subjected to a large tensile force and being broken.

[0052] When the gear rod 47 is reset to the left, the ratchet gear 31 rotates clockwise, and the ratchet tooth 322 is rotated by the inner ratchet tooth 311. The driven wheel 32 does not rotate, and the copper wire between the copper wire reel and the slider 43 is not subjected to tension and will not break.

[0053] In this embodiment, a plurality of receiving grooves 321 for accommodating the ratchet teeth 322 and the support springs 323 are opened on one side of the dynamic and passive wheels 32. When the ratchet teeth 322 rotate, they will be transferred into the receiving grooves 321, providing space for the rotation of the ratchet teeth 322, and the rotation of the ratchet teeth 322 can be limited in cooperation with the support springs 323.

[0054] In this embodiment, a track 48 for the gear rod 47 to slide is provided on the front side of the body 1, so that the movement of the gear rod 47 is more stable. A return spring 49 connected to one end of the gear rod 47 is provided in the track 48. No decompression spring 44 is provided in the slide groove 42 with the through groove 45 to avoid the decompression spring 44 getting stuck in the through groove 45 when compressed. The reset of the slider 43 in the slide groove 42 is achieved by the return spring 49.

[0055] In the present embodiment, the elastic coefficient of the pressure relief spring 44 gradually decreases from the pressure relief spring 44 close to the body 1 to the pressure relief spring 44 far from the body 1. When the copper wire is subjected to excessive tension, the compression amount from the pressure relief spring 44 close to the body 1 to the pressure relief spring 44 far from the body 1 can gradually increase, that is, the distance that the slider 43 can move from the slider 43 close to the body 1 to the slider 43 far from the body 1 gradually increases. The excessive tension on the copper wire increases gradually and will not increase instantly, which can effectively reduce the occurrence of wire breakage.

[0056] In this embodiment, the driving wheel 5 is in a gradually increasing tower shape in the direction away from the body 1, and an adapted number of copper wire die tracks are provided on the driving wheel 5 and the driven wheel assembly 3 to facilitate the thinning process of the copper wire.

[0057] In this embodiment, a driving assembly for driving the winding drum 6 to rotate and a traveling assembly for driving the winding drum 6 to move are provided on the back thereof. The driving assembly drives the winding drum 6 to rotate to wind up the copper wire, and the traveling assembly slowly approaches the driving wheel 5, that is, the winding drum 6 slowly approaches the driving wheel 5 when winding up the copper wire, so as to avoid the copper wire between the driving wheel 5 and the winding drum 6 being subjected to excessive tension and broken when the outer wall diameter of the winding drum 6 gradually increases during the winding process, and there is no need to use a complex control mechanism to control the winding speed of the winding drum 6, which greatly saves equipment cost and control accuracy required;

[0058] The driving assembly includes a driving motor 611 connected to the winding drum 6, and a reduction unit is provided on the driving motor 611. The driving motor 611 is used to drive the winding drum 6 to rotate to reel the copper wire, and the driving motor 611 controls the walking assembly to walk slowly through the reduction unit;

[0059] The walking assembly includes a walking block 621 that slides along the support rail 622 on the side wall of the machine body 1. The walking block 621 is rotatably connected to the shaft of the winding drum 6. The back of the walking block 621 is rotatably connected to a walking gear 623 that cooperates with a reduction unit. The back of the support rail 622 is provided with a rack 624 that meshes with the walking gear 623. The driving motor 611 drives the walking gear 623 to rotate slowly through the reduction unit. With the cooperation of the rack 624, the walking gear 623 drives the walking block 621 to move slowly toward the driving wheel 5. At this time, the walking block 621 drives the winding drum 6 to move slowly toward the driving wheel 5, so as to avoid excessive increase in tension on the copper wire between the driving wheel 5 and the winding drum 6 during the winding process and cause it to break.

[0060] In this embodiment, the reduction unit includes a first gear 612 arranged on the outer wall of the output end of the driving motor 611, the outer wall of the first gear 612 is meshedly connected with the second gear 613, the outer wall of the rotating shaft of the second gear 613 is provided with a third gear 614, the outer wall of the third gear 614 is meshedly connected with the fourth gear 615, and the outer wall of the rotating shaft of the fourth gear 615 is provided with a fifth gear 616 meshedly connected with the traveling gear 623. The driving motor 611 drives the second gear 613 to rotate through the first gear 612, and further makes the third gear 614 drive the fourth gear 615 to rotate. At this time, the fifth gear 616 drives the traveling gear 623 to rotate, and at this time the traveling block 621 can drive the winding drum 6 to move slowly toward the driving wheel 5.

[0061] In this embodiment, the diameter of the second gear 613 is larger than that of the first gear 612, the diameter of the third gear 614 is smaller than that of the second gear 613, the diameter of the fourth gear 615 is larger than that of the third gear 614, the diameter of the fifth gear 616 is smaller than that of the fourth gear 615, and the diameter of the traveling gear 623 is larger than that of the fifth gear 616. By using multiple gears with different diameters, the rotation speed of the traveling gear 623 is reduced, so that the traveling block 621 can drive the winding drum 6 to move slowly toward the driving wheel 5, thereby preventing the winding drum 6 from moving too fast toward the driving wheel 5, causing the wiring harness to loosen when winding.

[0062] Working principle: Select a suitable wire drawing die and install it on the slider 43. After the copper wire on the copper wire reel is wound, start the drive motor 611, and the reel 6 reels the copper wire.

[0063] When the tension on the copper wire is too large, the slider 43 drives the wire drawing die to move in the slide groove 42, and gradually compresses the plurality of pressure relief springs 44. At this time, the tension on the copper wire gradually increases and does not increase instantly, which can effectively reduce the occurrence of wire breakage.

[0064] When the tension on the copper wire is too large, the driven wheel 32 can rotate counterclockwise to feed the wire, and the copper wire on the copper wire drum is pulled to unwind the wire, thereby preventing the copper wire between the copper wire drum and the slider 43 from being broken due to a large tension.

[0065] When the winding drum 6 is winding the copper wire, the walking block 621 drives the winding drum 6 to move slowly toward the driving wheel 5 to avoid the copper wire between the driving wheel 5 and the winding drum 6 being subjected to excessive tension and breaking due to the gradual increase in the outer wall diameter of the winding drum 6 during the winding process.
