[0002] After the copper alloy wire is produced, its surface is usually rough. In order to improve the mechanical properties and surface finish of the wire, wire drawing treatment is required for the wire.

[0003] However, the existing devices are not convenient for keeping the angle of the wire entering the wire drawing die unchanged during wire drawing, and are prone to wire breakage due to stress concentration, reducing the wire drawing quality. Moreover, it is not convenient to pass the wire through the wire drawing die before wire drawing. Summary of the Invention

Rotating frames are rotatably connected to the rotating table and the side plates respectively. Torsion springs are connected between the two rotating frames and the rotating table and the side plates respectively. Clamping wheels are rotatably connected to the side of the two rotating frames close to each other. A limiting groove is formed in the clamping wheel. Two iron blocks are fixedly connected to the lower part of the rotating table. The two iron blocks are symmetrically distributed. A magnet is fixedly connected to the supporting bent plate. The magnet is in contact with the side of one of the iron blocks. A handle rod is fixedly connected to one side of the rotating table.

[0007] As a further preferred scheme, the fixing mechanism includes a long rod, which is rotatably connected to the supporting bent plate, a rotating gear is fixedly connected to the long rod, a rack bent rod is slidably connected to the supporting bent plate, the rack bent rod is meshed with the rotating gear, one side of the rack bent rod is fixedly connected to a guide straight plate, a straight groove is provided on the guide straight plate, a shift rod is fixedly connected to the side of the rotating platform away from the handle rod, the shift rod is located in the straight groove on the guide straight plate, swing rods are rotatably connected to both sides of the long rod, a return spring is connected between the swing rod and the long rod, and two rotating balls are rotatably connected to the upper parts of the two swing rods.

[0008] As a further preferred scheme, it also includes a perforation mechanism, which is arranged on a stand, and is used to assist in perforating the wire. The perforation mechanism includes a side block, and the side block is fixedly connected to a side of the stand close to the rotating roller. A swing piston cylinder is rotatably connected to the side block, and a torsion spring is connected between the swing piston cylinder and the side block. A contact tube is fixedly connected to the upper part of the swing piston cylinder, and the contact tube is communicated with the swing piston cylinder. The upper end of the contact tube is made of silicone material, and a piston pull rod is slidably connected to the swing piston cylinder, and a rotating groove rod is fixedly connected to the rotating shaft of the swing piston cylinder, and an oblique groove is opened on the rotating groove rod, and a toggle connecting rod is fixedly connected to the rack bending rod, and the toggle connecting rod cooperates with the rotating groove rod, and a trumpet tube rack is fixedly connected to the side of the stand away from the side block, and the trumpet tube rack contacts one side of the wire drawing die, and a rubber ring is placed in the trumpet tube rack.

[0009] As a further preferred scheme, it also includes a rotating mechanism, which is arranged on the water storage frame, and is used to rotate the wire when threading. The rotating mechanism includes a straight plate frame, which is fixedly connected to the inner bottom surface of the water storage frame, and the straight plate frame is rotatably connected to a shaking frame, and circular holes are opened on both sides of the shaking frame, and the shaking frame is rotatably connected to two rotating wheels, one of which is fixedly connected to a transmission gear at the lower part of the rotating wheel, and a rotating curved rod is rotatably connected to the lower part of the shaking frame, and a driven gear is fixedly connected to the rotating curved rod, and the driven gear is meshed with the transmission gear, and two cross bars are fixedly connected to the upper part of the straight plate frame.

[0010] The present invention has the following advantages: 1. The two clamping wheels clamp the wire, which can adapt to the wire passing through the clamping wheels at different angles. When the wire tilts up and down, the two clamping wheels will also tilt to adapt to the angle of the wire. In this way, after the wire passes through the clamping wheels, the direction of the wire is unified and unchanged, making the wire drawing through the wire drawing die more stable.

[0011] 2. When the operator turns the handle rod by 90°, the rack bent rod will move horizontally away from the fixed plate by a certain distance. Then the rack bent rod will drive the toggle link to move horizontally together. The horizontal movement of the toggle link will drive the rotating groove rod to rotate by 100°. The rotation of the rotating groove rod will drive the swinging piston cylinder block and the piston pull rod to rotate together. When the swinging piston cylinder block and the contact pipe rotate by 90°, one side of the contact pipe will contact one side of the wire drawing die, and the swinging piston cylinder block and the contact pipe will stop rotating. The continuous rotation of the rotating groove rod will cause the torsion spring to be twisted, and then the contact pipe will squeeze the side of the wire drawing die. Since one end of the contact pipe is made of silica gel, the contact between the contact pipe and the wire drawing die will be closer. Then the operator passes one end of the wire through the rubber ring and places it into the horn pipe holder. The rubber ring will wrap the wire, forming a sealed space between the piston pull rod and the wire. Then, pull the piston pull rod horizontally towards the rotating roller. According to the principle of atmospheric pressure, drive the wire to move horizontally and pass through the wire drawing die. Then turn the handle rod back to its original position, driving the swinging piston cylinder block to swing downward and return to its original position. Then, continue to limit and fix the wire passing through the wire drawing die, which can make it easier for the wire to pass through the die.

[0012] 3. Before passing the wire through the wire drawing die, pass one end of the wire through the round holes on both sides of the rocking frame successively. Then the fixed wire will be clamped by two rotating wheels. When the wire is pulled for wire drawing, the pulling of the wire will drive the two rotating wheels to rotate together. The rotation of the rotating wheels will drive the transmission gear to rotate together. The transmission gear will drive the rotating curved rod to rotate together through the driven gear. The rotation of the rotating curved rod will successively squeeze the cross bars on both sides. When the rotating curved rod squeezes one of the cross bars, the rotating curved rod will tilt, and then drive the rocking frame to tilt. When the rotating curved rod squeezes the other cross bar, the rotating curved rod will tilt in the opposite direction. This makes the rocking frame tilt and rock back and forth in small amplitudes. Since the two rotating wheels clamp the wire, the two rotating wheels will drive the wire to rotate back and forth as the rocking frame tilts and rocks back and forth in small amplitudes. When drawing copper wire, making the wire rotate back and forth can continuously change the contact position between the wire and the die, reduce stress concentration, and make it not easy for the wire to break during wire drawing.

[0027] Embodiment 1

[0028] A wire drawing device for copper alloy wire, as Figure 1-12 shown, includes a bottom table 1, a water storage frame 2 fixedly connected to the bottom table 1, a fixing plate 3 fixedly connected to the bottom table 1, a driving motor 4 fixedly connected to one side of the fixing plate 3, a rotating roller 5 rotatably connected to one side of the fixing plate 3, the rotating roller 5 being connected to the output shaft of the driving motor 4, a fixed roller 6 fixedly connected to one side of the fixing plate 3, a water pump 71 fixedly connected to one side of the fixing plate 3, a water spray pipe 72 fixedly connected to the water pump 71, a vertical platform 73 fixedly connected to the inner bottom surface of the water storage frame 2, a fastening bolt 74 threadedly connected to the vertical platform 73, a vertical frame 75 fixedly connected to the inner bottom surface of the water storage frame 2, a guide wheel 76 rotatably connected to the vertical frame 75, a groove being formed on the guide wheel 76, a wire drawing die 8 being placed on the vertical platform 73, a guiding mechanism being arranged on the water storage frame 2, the guiding mechanism being used for guiding the wire, and a fixing mechanism being arranged on the guiding mechanism, the fixing mechanism being used for fixing the wire reel.

[0029] The guiding mechanism includes side plates 91, the side plates 91 being fixedly connected to one side of the fixing plate 3, a supporting bent plate 92 fixedly connected to the water storage frame 2, a rotating table 93 rotatably connected to the supporting bent plate 92, rotating frames 94 rotatably connected to both the rotating table 93 and the side plates 91, torsion springs 95 being connected between the two rotating frames 94 and the rotating table 93 and the side plates 91 respectively, clamping wheels 96 rotatably connected to the mutually approaching sides of the two rotating frames 94, limiting grooves being formed on the clamping wheels 96, two iron blocks 97 fixedly connected to the lower part of the rotating table 93, the two iron blocks 97 being symmetrically distributed, a magnet 98 fixedly connected to the supporting bent plate 92, the magnet 98 being in contact with the side surface of one of the iron blocks 97, and a handle rod 99 fixedly connected to one side of the rotating table 93.

[0030] The fixing mechanism includes a long rod 101, the long rod 101 is rotatably connected to the support bent plate 92, a rotating gear 102 is fixedly connected to the long rod 101, a rack bent rod 103 is slidably connected to the support bent plate 92, the rack bent rod 103 meshes with the rotating gear 102, a guiding straight plate 104 is fixedly connected to one side of the rack bent rod 103, a straight groove is formed in the guiding straight plate 104, a dial rod 105 is fixedly connected to the side of the rotating table 93 away from the handle rod 99, the dial rod 105 is located in the straight groove on the guiding straight plate 104, swing rods 106 are rotatably connected to both sides of the long rod 101, a return spring 107 is connected between the swing rod 106 and the long rod 101, and two rotating beads 108 are rotatably connected to the upper parts of the two swing rods 106.

[0031] In actual work, first, fill the water storage frame 2 with water. Then, the operator needs to pull the handle rod 99 to rotate the handle rod 99 by 90°. The rotation of the handle rod 99 by 90° will drive the rotating table 93 and one of the clamping wheels 96 to rotate together. Then, the rotation of the rotating table 93 by 90° will drive the two iron blocks 97 to rotate by 90° together, causing one of the iron blocks 97 to disengage from the magnet 98 and the other iron block 97 to contact the magnet 98. The rotation of the rotating table 93 by 90° will drive the lever 105 to rotate together. The rotation of the lever 105 by 90° will drive the guiding straight plate 104 to move horizontally away from the fixed plate 3. The horizontal movement of the guiding straight plate 104 will drive the rack bent rod 103 to move horizontally away from the fixed plate 3 together. The horizontal movement of the rack bent rod 103 will drive the rotating gear 102 and the long rod 101 to rotate by 90° together. The rotation of the long rod 101 by 90° will drive the swinging rod 106 to swing downward by 90°. Then, the operator places the take-up reel that needs to be drawn on the fixed roller 6, places the winding reel on the rotating roller 5, then pulls out a part of the wire, passes the wire through the wire drawing die 8, and makes a part of the wire pass through the guiding wheel 76 and be guided by the groove on the guiding wheel 76. Then, the operator pulls the handle rod 99 back to its original position, driving one of the clamping wheels 96 back to its original position and making the two clamping wheels 96 clamp the wire in the middle, and the wire is located in the limiting groove on the clamping wheel 96. Finally, wind the wire around the winding reel, then tighten the wire. The reset of the handle rod 99 will ultimately drive the long rod 101 and the swinging rod 106 to reset. The upward swinging reset of the swinging rod 106 will cause the rotating ball 108 to limit the side of the wire reel placed on the rotating roller 5 and the fixed roller 6. Then, the operator starts the driving motor 4. The driving motor 4 will drive the rotating roller 5 to rotate. The rotation of the rotating roller 5 will drive the winding reel placed on it to rotate together, thereby pulling the wire continuously through the wire drawing die 8 to complete the wire drawing of the wire. The two clamping wheels 96 clamp the wire and can adapt to the wire passing through the clamping wheels 96 at different angles. When the wire is tilted up and down, the two clamping wheels 96 will also tilt to adapt to the angle of the wire. In this way, after the wire passes through the clamping wheels 96, the direction of the wire is unified and unchanged, making the wire drawing through the wire drawing die 8 more stable. Then, the water pump 71 pumps the water in the water storage frame 2 and sprays it to the wire drawing die 8 through the water spray pipe 72 to cool the wire.

[0032] Embodiment 2

[0033] On the basis of Embodiment 1, as Figure 7-9As shown, it also includes a perforating mechanism, which is arranged on the stand 73 and is used to assist in perforating the wire. The perforating mechanism includes a side block 111, which is fixedly connected to the side of the stand 73 close to the rotating roller 5. A swing piston cylinder 112 is rotatably connected to the side block 111, and a torsion spring 113 is connected between the swing piston cylinder 112 and the side block 111. A contact tube 114 is fixedly connected to the upper part of the swing piston cylinder 112, and the contact tube 114 is communicated with the swing piston cylinder 112. The contact tube 114 is connected to the swing piston cylinder 112. The upper end of 14 is made of silicone, a piston pull rod 115 is slidably connected to the swing piston cylinder 112, a rotating groove rod 116 is fixedly connected to the rotating shaft of the swing piston cylinder 112, and an oblique groove is opened on the rotating groove rod 116, a toggle connecting rod 117 is fixedly connected to the rack bending rod 103, and the toggle connecting rod 117 cooperates with the rotating groove rod 116, a horn tube rack 118 is fixedly connected to the side of the stand 73 away from the side block 111, the horn tube rack 118 is in contact with one side of the wire drawing die 8, and a rubber ring 119 is placed in the horn tube rack 118.

[0034] When the operator pulls the handle bar 99 and rotates it 90°, the rack bent rod 103 will move horizontally for a distance away from the fixed plate 3, and then the rack bent rod 103 will drive the toggle connecting rod 117 to move horizontally together. The horizontal movement of the toggle connecting rod 117 will drive the rotating slot rod 116 to rotate 100°. The rotation of the rotating slot rod 116 will drive the swing piston cylinder 112 and the piston pull rod 115 to rotate together. After the swing piston cylinder 112 and the contact tube 114 rotate 90°, one side of the contact tube 114 will contact one side of the wire drawing die 8, and the swing piston cylinder 112 and the contact tube 114 will stop rotating. The continued rotation of the rotating slot rod 116 will cause the torsion spring 113 to be twisted, thereby causing the contact tube 114 to rotate. It will squeeze the side of the wire drawing die 8. Since one end of the contact tube 114 is made of silicone, the contact between the contact tube 114 and the wire drawing die 8 will be closer. Then the operator will pass one end of the wire through the rubber ring 119 and put it into the trumpet tube holder 118. The rubber ring 119 will wrap the wire, so that a closed space is formed between the piston pull rod 115 and the wire. Then the piston pull rod 115 is pulled horizontally in the direction close to the rotating roller 5. Through the principle of atmospheric pressure, the wire is driven to move horizontally and pass through the wire drawing die 8. Then the handle rod 99 is pulled to reset, and the swing piston cylinder body 112 is driven to swing downward and reset. Then the wire that has passed through the wire drawing die 8 will continue to be limited and fixed, so that the wire can pass through the die more easily.

[0035] Example 3

[0036] On the basis of Example 2, Figure 10-12As shown, it also includes a rotating mechanism, which is arranged on the water storage frame 2, and is used to rotate the wire when threading. The rotating mechanism includes a straight plate frame 121, and the straight plate frame 121 is fixedly connected to the inner bottom surface of the water storage frame 2. A shaking frame 122 is rotatably connected to the straight plate frame 121, and round holes are opened on both sides of the shaking frame 122. Two rotating wheels 123 are rotatably connected to the shaking frame 122, and a transmission gear 124 is fixedly connected to the lower part of one of the rotating wheels 123. A rotating curved rod 125 is rotatably connected to the lower part of the shaking frame 122, and a driven gear 126 is fixedly connected to the rotating curved rod 125. The driven gear 126 is meshed with the transmission gear 124, and two cross bars 127 are fixedly connected to the upper part of the straight plate frame 121.

[0037] Before the wire is passed through the wire drawing die 8, one end of the wire is passed through the round holes on both sides of the rocking frame 122 respectively, and then the fixed wire will be clamped by the two rotating wheels 123. When the wire is pulled for wire drawing, the pulling of the wire will drive the two rotating wheels 123 to rotate together, and the rotation of the rotating wheel 123 will drive the transmission gear 124 to rotate together, and the transmission gear 124 will drive the rotating crank rod 125 to rotate together through the driven gear 126. The rotation of the rotating crank rod 125 will squeeze the cross bars 127 on both sides in turn. When the rotating crank rod 125 squeezes one of the cross bars 127, , the rotating curved rod 125 will tilt, thereby driving the rocking frame 122 to tilt. When the rotating curved rod 125 squeezes the other cross bar 127, the rotating curved rod 125 will tilt in the opposite direction, so that the rocking frame 122 can tilt and rock back and forth with a small amplitude. Since the two rotating wheels 123 clamp the wire, the two rotating wheels 123 can drive the wire to rotate back and forth as the rocking frame 122 tilts and rocks back and forth with a small amplitude. When drawing the copper wire, the reciprocating rotation of the wire can continuously change the contact position between the wire and the mold, thereby reducing stress concentration and making it less likely for the wire to break when drawing the wire.

[0038] The technical principles of the embodiments of the present invention are described above in conjunction with specific embodiments. These descriptions are only for explaining the principles of the embodiments of the present invention and cannot be interpreted in any way as limiting the protection scope of the embodiments of the present invention. Based on the explanations herein, those skilled in the art can think of other specific implementation methods of the embodiments of the present invention without creative work, and these methods will fall within the protection scope of the embodiments of the present invention.
