Description

Technical Field

[0001] The invention relates to the technical field of slitting machines, in particular to a copper wire slitting machine. Background Art

[0002] With the development of modern industry, copper wire has been widely used in many fields, such as electronic equipment, communication equipment, automotive parts, etc. In the copper wire processing process, it is often necessary to cut the copper wire according to a certain length to meet different production needs; and the traditional copper wire slitting mechanism has certain defects when slitting the copper wire, and it is difficult to ensure that the copper wire is fully corrected. In the process of slitting the copper wire, it is easy to cause the copper wire to bend, which affects the accuracy of the subsequent fixed slitting.

[0003] To this end, a Chinese patent with publication number "CN221018421U" announced "a fixed-length slitting machine for copper wire processing", whose main structure includes a base, a mounting seat, a fixed seat, a wire reel, a mounting groove and a conveying mechanism; the fixed-length slitting machine for copper wire processing, by setting a conveying mechanism, can clamp and convey the copper wire with two clamping pieces on the slider, and adjust the conveying length of the copper wire by the moving distance of the slider, so as to accurately cut the required length of the copper wire, straighten the copper wire, and ensure the accuracy of subsequent slitting of the copper wire.

[0004] When the above-mentioned fixed-length slitting machine for copper wire processing is slitting the copper wire, the electric push rod located on the base is started, and the upper blade is pushed to move vertically downward by the telescopic end of the electric push rod, so that the upper blade and the lower blade at the bottom of the knife seat can cooperate to cut the copper wire. Since the relative movement of the upper blade and the lower blade is not symmetrical about the copper wire, the copper wire will still bend during slitting. Summary of the invention

First, start the No. 1 driving motor 7, wind the steel wire to be cut into the copper wire winch wheel 5, when the whole roll of steel wire is wound, pass one end of the steel wire through the two steel wire clamping grooves 109, and place the wire body of the steel wire in the guide groove of the steel wire guide rail 8, and the preliminary cutting procedure can be completed.

[0021] In order to realize the rotational drive function of the steel wire and ensure the straight structure of the steel wire during the transportation process, please refer to Figure 1 , Figure 2 , Figure 4 and Figure 7 , it is necessary to set up a double-rotating wire driving mechanism 10, which is internally provided with a No. 1 gear 105 and a No. 2 gear 106 rotatably installed at the bottom of the workbench 1 and meshing with each other, a No. 2 driving motor 104 that can drive the No. 1 gear 105 to rotate, and two wire driving wheels 108 that can rotate with the No. 1 gear 105 and the No. 2 gear 106 and can produce a directional driving effect on the steel wire. When the No. 2 driving motor 104 is started, the No. 1 gear 105 and the No. 2 gear 106 will present a synchronous reverse rotation state. At this time, the two wire driving wheels 108 will produce a synchronous and unidirectional driving effect on the two symmetrical contact surfaces of the steel wire, thereby driving the steel wire to move toward the guide groove of the steel wire guide rail 8 to ensure the structural shape of the copper wire before slitting and prevent it from bending.

[0022] For the specific structure of the dual-rotation wire drive mechanism 10, please refer to Figure 7 , including an L-shaped connecting plate 101, a first gear 105 and a second gear 106, wherein the longitudinal end of the L-shaped connecting plate 101 is provided with a first fixing plate 102 which is an integral structure with the L-shaped connecting plate 101 and is fixedly mounted on the lower surface of the workbench 1, and the transverse end of the L-shaped connecting plate 101 is provided with a second motor fixing seat 103 which is an integral structure with the L-shaped connecting plate 101, wherein a second driving motor 104 in a longitudinal state is fixedly mounted inside the second motor fixing seat 103, and a first gear 105 is fixedly mounted on the top of the second driving motor 104, and an edge structure of the first gear 105 meshes with a second gear 106, and the upper ends of the first gear 105 and the second gear 106 A No. 3 rotating shaft 107 is fixedly installed on each surface, and the shaft body of each No. 3 rotating shaft 107 is correspondingly installed in a No. 1 shaft body mounting hole 3 through a bearing. A wire driving wheel 108 is fixedly installed on the top of each No. 3 rotating shaft 107. In order to achieve a synchronous driving effect, it is necessary to make the two wire driving wheels 108 symmetrically arranged with respect to the symmetry plane of the wire guide rail 8, and the circumferential surfaces of the two wire driving wheels 108 are provided with wire clamping grooves 109. In order to achieve an effective driving effect on the steel wire, it is necessary to make the size of the clamping area formed by the two wire clamping grooves 109 match the size of the cross-section of the clamped steel wire.

[0023] To achieve a symmetrical pinch-off effect on the wire, see Figure 1 , Figure 2 and Figure 8, it is necessary to set up a reverse symmetrical cutting mechanism 11, which is provided with a piston body 117 that can move synchronously toward the symmetry plane under the action of gas pressure, and a cutting head 1110 that moves with the piston body 117 and can produce a pinching effect on the steel wire. Before work, it is necessary to connect the gas docking channel 1111 with the gas circuit of an air compressor. When the steel wire moves between the two cutting heads 1110, start the air compressor. At this time, the compressed gas instantly enters the active chambers 115 of the two horizontal components. Under the action of the gas, the piston body 117 drives the two cutting heads 1110 to quickly clamp the steel wire, and then, the gas reflux program of the air compressor is started. Under the elastic action of the No. 2 coil spring 118, the piston body 117 will drive the two cutting heads 1110 to reset away from each other, thereby achieving a symmetrical clamping effect on the steel wire. Since the steel wire is cut by two cutting heads 1110 that move synchronously and in opposite directions, it can ensure that the force on the steel wire during cutting is kept on the symmetrical plane, thereby ensuring the structural shape of the steel wire at the cutting position.

In order to prevent the component from rotating, it is necessary to make the structural shape of the cross section of the component telescopic hole 116 and the structural shape of the cross section of the horizontal telescopic rod 119 consistent, both of which are polygonal structures, and the structural dimensions of the cross section of the component telescopic hole 116 match the structural dimensions of the cross section of the horizontal telescopic rod 119. The horizontal telescopic rod 119 is sheathed with a No. 2 coil spring 118 in a compressed state on the outer periphery of the rod body located inside the horizontal component movable cavity 115. The No. 2 coil spring 118 generates elastic pressure on the piston body 117 to move away from the component telescopic hole 116. The horizontal telescopic rod 119 is fixedly installed with a cutting head 1110 at one end located outside the horizontal hollow tube 114.

[0025] In order to keep the steel wire in a straight state during transportation, please refer to Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6, it is necessary to set up a combined linkage mechanism 9, which is provided with a rotatable transverse hollow shaft 91, a polygonal movable plate 97 placed inside the transverse hollow shaft 91 and capable of rotating with the transverse hollow shaft 91, a first rotating disk 910 located inside the transverse hollow shaft 91 and capable of moving with the polygonal movable plate 97, a second rotating disk 911 located inside the transverse hollow shaft 91 and capable of rotating, and a second rotating disk 911 placed between the first rotating disk 910 and the second rotating disk 911 and capable of enabling the first rotating disk 910 to drive the second rotating disk The transmission ball 914 of the rotating disk 911 starts the No. 1 driving motor 7, and the No. 1 driving motor 7 drives the No. 2 rotating disk 911 to rotate through the No. 2 docking flange 916 and the No. 2 rotating shaft 915, and the No. 2 rotating disk 911 will drive the No. 1 rotating disk 910 to rotate through the transmission ball 914 arranged in the ring array, and the No. 1 rotating disk 910 will drive the polygonal movable plate 97 to rotate through the No. 1 rotating shaft 99, and the rotation torque resistance during the rotation process is greater than the No. 1 spiral spring 98. In other words, the pressure of the No. 1 coil spring 98 on the No. 1 rotating disk 910 and the transmission ball 914 is insufficient, and the torque resistance will be transmitted to the transmission ball 914 and the No. 1 rotating disk 910. According to the force analysis, at this time, the transmission ball 914 is in the No. 1 hemispherical groove 912, and the upward component force is greater than the downward pressure of the No. 1 coil spring 98, and the No. 1 rotating disk 910 will move upward, which will cause the transmission ball 914 to break away from the No. 1 rotating disk 910 and rotate relatively. At this time, The torque resistance will not continue to increase, the No. 2 rotating disk 911 is in a rotating phenomenon, and the No. 1 rotating disk 910 is in a reverse phenomenon under the tension of the wire driving wheel 108. Therefore, when setting, the tension of the No. 1 driving motor 7 on the wire and the tension of the wire driving wheel 108 on the wire are required to be in opposite directions, so that the wire is always in a straight state during the transportation process to prevent the wire from deforming during the transportation process. Of course, the two reverse forces need to meet the following requirements: the force will not cause the wire to break.

[0026] For the specific structure of the combined linkage mechanism 9, please refer to Figure 5 and Figure 6, including a transverse hollow shaft 91, one end face of which is provided with a No. 1 docking flange 92 fixedly connected to a rotating end of the copper wire winch wheel 5, the transverse hollow shaft 91 is provided with a polygonal movable cavity 93 at one end close to the No. 1 docking flange 92, the transverse hollow shaft 91 is provided with a No. 1 shaft body through hole 94 at one end located in the polygonal movable cavity 93, the transverse hollow shaft 91 is provided with a cylindrical movable cavity 95 at one end located in the No. 1 shaft body through hole 94, the other end of the transverse hollow shaft 91 is provided with a No. 2 shaft body through hole 96 connecting the cylindrical movable cavity 95 and the external space, the transverse hollow shaft 91 is provided with a No. 2 shaft body through hole 96 connecting the cylindrical movable cavity 95 and the external space, and the transverse hollow shaft 91 is provided with a The polygonal movable plate 97 that moves axially in the movable cavity 93 needs to make the structural shape of the cross section of the polygonal movable cavity 93 consistent with the structural shape of the cross section of the polygonal movable plate 97, both of which are polygonal structures, and the structural dimensions of the cross section of the polygonal movable cavity 93 match the structural dimensions of the cross section of the polygonal movable plate 97. The polygonal movable plate 97 is provided with a No. 1 coil spring 98 in a compressed state on the end face facing the No. 1 docking flange 92, and the other end face of the polygonal movable plate 97 is provided with a No. 1 rotating shaft 99 that is integrally structured with it and passes through the No. 1 shaft body through-hole 94, and one end of the No. 1 rotating shaft 99 extends to the interior of the cylindrical movable cavity 95. , and the No. 1 rotating shaft 99 is provided with a No. 1 rotating disk 910 of an integral structure therewith at one end located inside the cylindrical movable cavity 95, the No. 2 rotating shaft 91 is installed with a No. 2 rotating shaft 915 capable of rotation through a bearing inside the No. 2 shaft body through-hole 96, the No. 2 rotating shaft 915 is provided with a No. 2 rotating disk 911 of an integral structure therewith at one end located inside the cylindrical movable cavity 95, the No. 1 rotating disk 910 is provided with a plurality of No. 1 hemispherical grooves 912 in an annular array inside the end face facing the No. 2 rotating disk 911, the No. 2 rotating disk 911 is provided with a No. 2 hemispherical groove 913 on the end face corresponding to the No. 1 hemispherical groove 912, and each corresponding No. 1 hemispherical groove 913 is provided on the end face corresponding to the No. 1 hemispherical groove 912. A transmission ball 914 is placed inside each of the groove 912 and the second hemispherical groove 913. In order to realize the transmission function of the rotation phenomenon and have the ability to disengage, it is necessary to make the structural radius of the first hemispherical groove 912, the structural radius of the second hemispherical groove 913 and the structural radius of the transmission ball 914 consistent, and the depth of the first hemispherical groove 912 is smaller than the structural radius of the transmission ball 914, and the structural depth of the second hemispherical groove 913 is greater than the structural radius of the transmission ball 914. The other end of the second rotating shaft 915 is provided with a second docking flange 916 with an integral structure therewith, and the second docking flange 916 is fixedly connected to the rotor end of the first drive motor 7.

[0027] The specific working principle of the present invention is as follows: first, start the No. 1 driving motor 7, wind the steel wire to be cut into the copper wire winch wheel 5, and when the whole roll of steel wire is wound, pass one end of the steel wire through the two steel wire clamping grooves 109, and place the wire body of the steel wire in the guide groove of the steel wire guide rail 8, and connect the gas docking channel 1111 with the gas circuit of a gas compressor; Start the No. 2 driving motor 104, the No. 1 gear 105 and the No. 2 gear 106 will present a synchronous counter-rotation state, at this time, the two wire driving wheels 108 will produce a synchronous and unidirectional driving effect on the two symmetrical contact surfaces of the wire, thereby driving the wire to move toward the guide groove of the wire guide rail 8; At the same time, starting the No. 1 drive motor 7 requires the No. 1 drive motor 7 to pull the wire in opposite directions to the wire drive wheel 108. During the operation of the equipment, the rotation torque resistance is greater than the strength of the resistance pressure formed by the No. 1 coil spring 98. The No. 1 coil spring 98 indirectly exerts insufficient pressure on the No. 1 rotating disk 910 and the transmission ball 914. The torque resistance will be transmitted to the transmission ball 914 and the No. 1 rotating disk 910. According to the force analysis, at this time, the transmission ball 914 is in the No. 1 hemispherical groove 912, and the upward component force is greater than the No. 1 hemispherical groove 912. The downward pressure of the No. 1 coil spring 98 will cause the No. 1 rotating disk 910 to move upward, which will cause the transmission ball 914 to separate from the No. 1 rotating disk 910 and rotate relatively. At this time, the torque resistance will not continue to increase, the No. 2 rotating disk 911 is in a rotating phenomenon, and the No. 1 rotating disk 910 is reversed under the pulling force of the wire driving wheel 108, so that the wire is always in a straight state during the transportation process to prevent the wire from being deformed during the transportation process. Of course, the two reverse forces need to meet the following requirements: the force will not cause the wire to break; Start the air compressor. At this time, compressed gas instantly enters the active chamber 115 of the two horizontal components.
