Description

Technical Field

[0001] The invention belongs to the technical field of enameled wire processing, and in particular relates to a wire drawing device for enameled wire production. Background Art

[0002] Enameled wire is a cable with an outer layer of insulating paint, usually used for windings of motors and transformers. Enameled wire usually needs to be drawn during the production process, and drawing is an important step. Specifically, wire drawing is a continuous stretching process of metal wire (usually copper or aluminum) to turn it into a slender wire with a specific diameter. This process not only changes the diameter of the wire, but also improves the mechanical strength of the wire, making it less likely to break during use; controls the wire diameter to meet specific application requirements; improves electrical conductivity to ensure efficient current transmission; and enhances the insulation performance of the wire to improve its durability and reliability. These characteristics make enameled wire perform well in motors, transformers and other electronic equipment.

[0003] Existing wire drawing usually uses a wire drawing device. First, the enameled wire is manually threaded through a wire drawing die, and then automatically drawn by the wire drawing device. Although the enameled wire can be automatically drawn, each time the reel reels the drawn enameled wire, it is necessary to manually load and unload the material, thereby increasing labor costs. In addition, the wire drawing dies on the existing wire drawing devices are almost all fixedly installed. When enameled wires of different diameters need to be drawn, the staff needs to dismantle the old wire drawing dies and then install different types of wire drawing dies. The operation is not only complicated, but also affects the processing efficiency. Summary of the invention

[0014] Furthermore, the wire drawing mechanism includes a second mounting bracket fixedly connected to the top center of the supporting base frame, the top of the second mounting bracket is fixedly connected to a wire drawing box, one side of the center of the wire drawing box is rotatably connected to a driving shaft, and the other side of the center of the wire drawing box is rotatably connected to a driven shaft, the outer walls of the driving shaft and the driven shaft are fixedly connected to a tower wheel, the rear end of the wire drawing box is fixedly installed with a first motor, the front end of the output shaft of the first motor is fixedly connected to the rear end of the driving shaft, and the center of the wire drawing box is fixedly connected with a stepped seat, and a plurality of mounting grooves are provided on the top of the stepped seat, and the first wire drawing die, the second wire drawing die and the second wire drawing die are respectively installed in the plurality of mounting grooves.

[0015] Through the above technical scheme, when the wire body needs to be drawn to a specified diameter, the first wire drawing die, the second wire drawing die, the third wire drawing die and the fourth wire drawing die are respectively placed in the corresponding installation grooves, the wire body is wound around the two tower wheels and passes through the first wire drawing die, the second wire drawing die, the third wire drawing die, the fourth wire drawing die and the stepped seat, the first motor is started, and the first motor drives the drive shaft to rotate through the output shaft rotation, thereby driving the tower wheel connected to it to rotate, and the other tower wheel rotates accordingly. At this time, the wire body passes through the first wire drawing die, the second wire drawing die, the third wire drawing die and the fourth wire drawing die in sequence.

[0017] The second motor is reset, so that the first baffle is rotated out of the adjacent limiting groove and pressed against the second winding drum, and the piston of the first hydraulic cylinder is continuously pushed down to push the winding drum, and then fixed it by the fixing mechanism, and the first hydraulic cylinder is reset. After the winding drum winds up the drawn wire body, it is lowered to the feeding rack by the first hydraulic cylinder, and automatically rolls to the other side of the feeding rack, thereby completing automatic loading and unloading, and greatly improving the wire drawing efficiency of the enameled wire.

[0018] Furthermore, the wire drawing mechanism includes a wire guide wheel rotatably connected to the top of the front end of the first fixed frame, a screw rod is rotatably connected to one side between the first fixed frame and the second fixed frame, two limit rods are fixedly connected to one side between the first fixed frame and the second fixed frame, the two limit rods are respectively located on both sides of the screw rod, a nut seat is spirally connected to the screw rod, the nut seat is slidably connected to the two limit rods, a third motor is fixedly installed on the rear end of the first fixed frame, the front end of the third motor output shaft is fixedly connected to the rear end of the screw rod, a wire drawing wheel is installed on one side of the nut seat, and the wire body is wound around the wire guide wheel and the wire drawing wheel.

[0019] Through the above technical scheme, the wire body passes through the guide wheel and the wire drawing wheel. When the winding drum automatically reels the drawn wire body, the third motor is started. The third motor drives the lead screw to rotate through the output shaft, thereby driving the nut seat to move, and then driving the wire drawing wheel to move, so as to facilitate the uniform winding of the wire body around the outside of the winding drum, prevent the wire jamming phenomenon, and improve the winding efficiency of the wire body.

[0020] Furthermore, the fixing mechanism includes a fixing seat fixedly connected to the rear end center of the first fixing frame, the front end of the fixing seat is fixedly connected to the first connecting shaft, the front end of the first connecting shaft is rotatably connected to the first fixing head and passes through the first fixing frame, the front end center of the second fixing frame is fixedly connected to the third fixing frame, the top front end of the third fixing frame is fixedly installed with a second hydraulic cylinder, the rear end of the second hydraulic cylinder piston is fixedly connected to the connecting frame, the connecting frame is slidably connected to the third fixing frame, the rear end center of the connecting frame is rotatably connected to the second connecting shaft, one end of the second connecting shaft is fixedly connected to the second fixing head and passes through the second fixing frame, the fourth motor is fixedly installed on the connecting frame, the rear end of the fourth motor output shaft is fixedly connected to the front end of the second connecting shaft, and the first fixed head and the second fixed head respectively squeeze the front and rear ends of the winding drum.

[0021] Through the above technical scheme, when the positioning and lifting mechanism lifts the winding drum to the same horizontal plane as the first fixed head and the second fixed head, the second hydraulic cylinder is started, so that the second hydraulic cylinder pushes the connecting frame through the piston, thereby pushing the second connecting shaft, and then pushing the second fixed head, so that the second fixed head pushes the winding drum, so that the winding drum is pushed to fit with the first fixed head. At this time, the first fixed head and the second fixed head are respectively inserted into the center hole of the winding drum, and fit tightly with the front and rear ends of the center hole of the winding drum. The fourth motor is started, and the fourth motor drives the second connecting shaft to rotate through the output shaft, thereby driving the second fixed head to rotate. Since the first fixed head is rotatably connected to the first connecting shaft, it drives the winding drum to rotate, thereby realizing automatic fixation of the winding drum and automatic winding of the line body without manual intervention, and the automation efficiency is high.

[0022] Furthermore, the wire winding mechanism includes a rotating seat fixedly connected to the front end center of the first fixed frame, the inner wall of the rotating seat is rotatably connected to a rotating sleeve, the front end of the rotating sleeve is fixedly connected to a rotating disk, the rear end of the outer wall of the rotating sleeve is fixedly connected to a first gear, the rear end side of the first fixed frame is fixedly connected to a machine base, a fifth motor is fixedly installed on the top of the machine base, the outer wall of the fifth motor output shaft is fixedly connected to a second gear, the first gear is meshed with the second gear, the front end top of the rotating disk is fixedly connected to a first clamp, the front end top of the rotating disk and the first cylinder is fixedly installed in the first clamp, the front end of the first cylinder piston is fixedly connected to the second clamp and passes through the first clamp, and an arc-shaped opening is opened on the rotating disk.

[0023] Through the above technical scheme, after the drawn wire is wound on the take-up drum, it needs to be unloaded and the fifth motor is started. The fifth motor drives the second gear to rotate through the output shaft, thereby driving the first gear to rotate. The rotation of the first gear drives the rotating sleeve to rotate, and then drives the rotating disk to rotate, and the first clamp and the second clamp are rotated until they contact the wire under the wire drawing wheel. At this time, the first cylinder is started, and the first cylinder pushes the second clamp through the piston, so that the wire is approached between the first clamp and the second clamp through tension. The first cylinder is reset again, driving the second clamp to clamp the wire, and it is cut off by the wire cutting mechanism at this time to complete the winding step of the take-up drum. When the new winding drum is wound at this time, one end of the cut wire body is clamped by the first clamp and the second clamp, and the rotating disk rotates to drive one end of the wire body to rotate around the new winding drum. After a certain number of rotations, and the first clamp and the second clamp are rotated to the initial position, the piston of the first cylinder pushes and resets, so that the first clamp and the second clamp release the clamping of the wire body, and then the new winding drum is wound on the wire body through the fixing mechanism. The mechanism automatically cuts the wound winding drum and automatically winds the wire on the new winding drum. The whole process is automated and no manual operation is required by the staff, which greatly improves the wire drawing efficiency.

[0027] Through the above technical solution, when the winding drum needs to be unloaded after winding, in order to facilitate the winding drum to slide in the two slide grooves, the third cylinder is started at this time, so that the third cylinder pushes the push plate through the piston, so that the push plate pushes the rear end of the winding drum, so that the winding drum is pushed to the position directly above the two slide grooves.

[0028] The beneficial effects of the present invention are as follows: (1) The present invention designs a positioning ejection mechanism, a fixing mechanism, a winding mechanism and a pushing mechanism, and each mechanism cooperates with each other to automatically unload the material from the take-up drum and automatically load the material to the new take-up drum without manual operation by the staff, which not only greatly reduces the labor cost but also improves the wire drawing efficiency; (2) The present invention designs a wire drawing mechanism, and the wire drawing mechanism is provided with a plurality of wire drawing dies.

[0056] The working principle of this embodiment is as follows. When a new batch of wire bodies 203 need to be drawn, the wire bodies 203 are wound on the discharge reel 202, passed through the wire holder 302 and a plurality of straightening wheels 303 in sequence, and then passed through the wire drawing box 402, and then wound through two tower wheels 405. When the wire body 203 needs to be drawn to a specified diameter, it is passed through the set first wire drawing die 409, the second wire drawing die 410, the third wire drawing die 411, the fourth wire drawing die 412 and the stepped seat 407, and the first wire drawing die 409, the second wire drawing die 410, the third wire drawing die 411 and the fourth wire drawing die 412 are placed in the corresponding installation groove 408, and then passed through the guide wire wheel 901 and the wire drawing wheel 906, and then wound on the new winding drum 53. At this time, the winding drum 53 is fixed;

[0057] The first motor 406 is started, and the first motor 406 drives the drive shaft 403 to rotate by rotating the output shaft, and then drives the tower pulley 405 connected thereto to rotate, and the other tower pulley 405 rotates accordingly, drawing the wire body 203 on the reel 202, so that the wire body 203 passes through multiple straightening wheels 303 to be straightened. At this time, the wire body 203 sequentially passes through the first wire drawing die 409, the second wire drawing die 410, the third wire drawing die 411 and the fourth wire drawing die 412, so that the diameter is squeezed and reduced in turn to achieve wire drawing processing, and at the same time, the water pump 416 is started, and the water pump 416 draws the coolant in the cooling box 413 through the first connecting pipe 417, and then transports it to the nozzle 414 through the second connecting pipe 418, and then distributes it through multiple nozzles 415. The first wire drawing die 409, the second wire drawing die 410, the third wire drawing die 411 and the fourth wire drawing die 412 are sprayed for cooling, and the fourth motor 1009 is started at the same time. The fourth motor 1009 drives the second connecting shaft 1007 to rotate through the output shaft rotation, thereby driving the second fixed head 1008 to rotate. Since the first fixed head 1003 is rotatably connected with the first connecting shaft 1002, the winding drum 53 is driven to rotate. At the same time, the third motor 905 is started. The third motor 905 drives the lead screw 902 to rotate through the output shaft rotation, thereby driving the nut seat 904 to move, and then driving the wire drawing wheel 906 to move, so that the wire body 203 is evenly wound around the outer side of the winding drum 53, and the wire body 203 that has been drawn is automatically wound;

[0058] After the winding drum 53 winds up the drawn wire 203, the fifth motor 1106 is started. The fifth motor 1106 drives the second gear 1107 to rotate through the output shaft, thereby driving the first gear 1104 to rotate. The rotation of the first gear 1104 drives the rotating sleeve 1102 to rotate, and then drives the rotating disk 1103 to rotate, and rotate the first clamp 1108 and the second clamp 1110 to contact the wire 203 under the wire drawing wheel 906. At this time, the first cylinder 1109 is started. The first cylinder 1109 pushes the second clamp 1110 through the piston, so that the wire 203 is approached between the first clamp 1108 and the second clamp 1110 through tension. The first cylinder 1109 is reset again, driving the second clamp 1110 to clamp the wire 203, and then the second cylinder is started. 1202, so that the second cylinder 1202 pushes the wire cutter 1203 through the piston, so that the wire cutter 1203 is pushed to quickly cut the wire body 203, and then the first hydraulic cylinder 807 is started, and the first hydraulic cylinder 807 pushes the top plate 808 through the piston, thereby pushing the arc support plate 809, so that the arc support plate 809 is lifted and fits with the winding drum 53, and then the third cylinder 1302 is started, so that the third cylinder 1302 pushes the push plate 1303 through the piston, so that the push plate 1303 pushes the rear end of the winding drum 53, so that the winding drum 53 is pushed to the position just above the two slide grooves 51, and then the first hydraulic cylinder 807 drives the winding drum 53 to descend, so that the winding drum 53 just slides in the two slide grooves 51, and automatically rolls to the other side of the feeding rack 5, and the unloading is completed;

[0059] When it is necessary to load a new winding drum 53, the second motor 805 is started, and the second motor 805 drives the rotating shaft 801 to rotate through the output shaft rotation, thereby driving the two rotating frames 802 to rotate, and then driving the first stop bar 803 and the second stop bar 804 to rotate, so that the first stop bar 803 rotates to the limit groove 52 below it, and the second stop bar 804 rotates out from the adjacent limit groove 52. At this time, the winding drum 53 automatically slides through the inclined surface of the feeding frame 5 and is blocked by the second stop bar 804. Then, the winding drum 53 is lifted to the same horizontal plane as the first fixed head 1003 and the second fixed head 1008 through the first hydraulic cylinder 807, the top plate 808 and the arc support plate 809, and the second hydraulic cylinder 1005 is started, so that the second hydraulic cylinder 1005 pushes the connecting frame 1006 through the piston, thereby pushing the second connecting shaft 1007, and then pushing the second fixed head 1008, so that the second fixed head 1008 pushes The first and second fixed heads 1003 and 1008 are respectively inserted into the center holes of the winding drum 53 and are tightly fitted with the front and rear ends of the center holes of the winding drum 53 to realize automatic fixing of the winding drum 53. After fixing, the first hydraulic cylinder 807 is reset. At this time, the rotating disk 1103 rotates to drive the first clamping head 1108 and the second clamping head 1110 to clamp the cut wire body 203, thereby driving one end of the wire body 203 to rotate around the new winding drum 53. After rotating a certain number of times, and the first clamping head 1108 and the second clamping head 1110 rotate to the initial position, the piston of the first cylinder 1109 is pushed and reset again, so that the first clamping head 1108 and the second clamping head 1110 release the clamping of the wire body 203, and then the new winding drum 53 is used to wind up the wire body 203 through the fixing mechanism 10, and the wire body 203 is wound by the same principle.
