Description

Technical Field

[0001] This invention relates to the field of copper wire drawing, and more particularly to a copper alloy wire drawing device. Background Technology

[0002] After copper alloy wire is produced, the surface is usually rough. In order to improve the mechanical properties and surface finish of the wire, it is necessary to draw the wire.

[0003] However, existing devices are not convenient for maintaining the angle of the wire entering the drawing die during wire drawing, which can easily cause wire breakage due to stress concentration, reducing the quality of wire drawing. Furthermore, it is not convenient to pass the wire through the drawing die before drawing. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a copper alloy wire drawing device that makes wire threading more convenient, and can keep the angle of the wire entering the drawing die unchanged during wire drawing, making it less likely to break and improving the drawing quality.

[0005] The technical solution is as follows: A copper alloy wire drawing device includes a base platform, a water storage frame fixedly connected to the base platform, a fixing plate fixedly connected to the base platform, a drive motor fixedly connected to one side of the fixing plate, a rotating roller rotatably connected to one side of the fixing plate, the rotating roller being connected to the output shaft of the drive motor, a fixing roller fixedly connected to one side of the fixing plate, a water pump fixedly connected to one side of the fixing plate, a water spray pipe fixedly connected to the water pump, a vertical platform fixedly connected to the bottom surface inside the water storage frame, fastening bolts threadedly connected to the vertical platform, a support frame fixedly connected to the bottom surface inside the water storage frame, a guide wheel rotatably connected to the support frame, the guide wheel having a groove, a wire drawing die placed on the vertical platform, a guiding mechanism provided on the water storage frame for guiding the wire, and a fixing mechanism provided on the guiding mechanism for fixing the wire reel.

[0006] As a further preferred embodiment, the guiding mechanism includes a side plate fixedly connected to one side of the fixed plate. A supporting curved plate is fixedly connected to the water storage frame. A rotating platform is rotatably connected to the supporting curved plate. Rotating frames are rotatably connected to both the rotating platform and the side plate. Torsion springs are connected between the two rotating frames and the rotating platform and the side plate, respectively. Clamping wheels are rotatably connected to the sides of the two rotating frames that are close to each other. Limit grooves are opened on the clamping wheels. Two iron blocks are fixedly connected to the lower part of the rotating platform. The two iron blocks are symmetrically distributed. A magnet is fixedly connected to the supporting curved plate. The magnet is in contact with the side of one of the iron blocks. A handle is fixedly connected to one side of the rotating platform.

[0007] As a further preferred embodiment, the fixing mechanism includes a long rod rotatably connected to the support plate. A rotating gear is fixedly connected to the long rod. A rack and pinion is slidably connected to the support plate, meshing with the rotating gear. A guide plate is fixedly connected to one side of the rack and pinion, and a straight groove is formed on the guide plate. A lever is fixedly connected to the side of the rotating platform away from the handle, and the lever is located in the straight groove on the guide plate. Swing rods are rotatably connected to both sides of the long rod, and a return spring is connected between the swing rods and the long rod. Two ball bearings are rotatably connected to the upper part of each of the two swing rods.

[0008] As a further preferred embodiment, a perforation mechanism is also included. This perforation mechanism is mounted on a vertical platform and is used to assist in wire perforation. The perforation mechanism includes a side block, which is fixedly connected to the side of the vertical platform near the rotating roller. A swing piston cylinder is rotatably connected to the side block, and a torsion spring connects the swing piston cylinder to the side block. A contact tube is fixedly connected to the upper part of the swing piston cylinder, communicating with the swing piston cylinder. The upper end of the contact tube is made of silicone. A piston rod is slidably connected to the swing piston cylinder. A rotating groove rod is fixedly connected to the rotating shaft of the swing piston cylinder, and the rotating groove rod has an oblique groove. A toggle link is fixedly connected to the rack and pinion, and the toggle link cooperates with the rotating groove rod. A horn tube frame is fixedly connected to the side of the vertical platform away from the side block, and the horn tube frame contacts one side of the wire drawing die. A rubber ring is placed inside the horn tube frame.

[0009] As a further preferred embodiment, a rotating mechanism is also included, which is disposed on the water storage frame. The rotating mechanism is used to rotate the wire during threading. The rotating mechanism includes a straight plate frame, which is fixedly connected to the bottom surface of the water storage frame. A rocking frame is rotatably connected to the straight plate frame. The rocking frame has round holes on both sides. Two rotating wheels are rotatably connected to the rocking frame. A transmission gear is fixedly connected to the lower part of one of the rotating wheels. A rotating crank is rotatably connected to the lower part of the rocking frame. A driven gear is fixedly connected to the rotating crank, and the driven gear meshes with the transmission gear. Two crossbars are fixedly connected to the upper part of the straight plate frame.

[0010] The present invention has the following advantages: 1. Two clamping wheels clamp the wire, which can adapt to the wire passing through the clamping wheels at different angles. When the wire is tilted up and down, the two clamping wheels will also tilt to adapt to the angle of the wire. This makes the direction of the wire uniform and unchanged after passing through the clamping wheels, making the wire more stable when drawn by the drawing die.

[0011] 2. When the operator rotates the handle by 90°, the rack and pinion will move horizontally a certain distance away from the fixed plate. Then, the rack and pinion will drive the connecting rod to move horizontally as well. This horizontal movement of the connecting rod will cause the rotating groove rod to rotate 100°. The rotation of the rotating groove rod will then cause the swing piston cylinder and piston rod to rotate together. After the swing piston cylinder and contact tube have rotated 90°, one side of the contact tube will contact the side of the wire drawing die, and the swing piston cylinder and contact tube will stop rotating. The continued rotation of the rotating groove rod will twist the torsion spring, causing the contact tube to press against the side of the wire drawing die. Since one end of the contact tube is made of silicone, the contact between the contact tube and the drawing die is made more tightly. Then, the operator passes one end of the wire through the rubber ring and puts it into the speaker tube frame. The rubber ring will wrap around the wire, so that a sealed space is formed between the piston rod and the wire. Then, the piston rod is pulled horizontally towards the rotating roller. Through the principle of atmospheric pressure, the wire is moved horizontally and passes through the drawing die. Then, the handle is turned to reset, which causes the swing piston cylinder to swing downward to reset. Then, the wire that has passed through the drawing die is further limited and fixed. This makes it easier for the wire to pass through the die.

[0012] 3. Before passing the wire through the drawing die, pass one end of the wire through the round holes on both sides of the rocking frame. The fixed wire will then be held by two rotating wheels. When the wire is pulled for drawing, the wire will cause 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 crank to rotate together through the driven gear. The rotating crank will press against the crossbars on both sides. When the rotating crank presses against one of the crossbars, the rotating crank will tilt, which will in turn cause the rocking frame to tilt. When the rotating crank presses against the other crossbar, the rotating crank will tilt in the opposite direction. This causes the rocking frame to tilt and rock back and forth with small amplitude. Since the two rotating wheels hold the wire, the two rotating wheels will cause the wire to rotate back and forth with small amplitude tilting and rocking of the rocking frame. During copper wire drawing, the reciprocating rotation of the wire can make the contact position between the wire and the die constantly change, reducing stress concentration and making the wire less likely to break during drawing.

Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0027] Example 1

[0028] A copper alloy wire drawing device, such as Figure 1-12 As shown, the device includes a base platform 1, a water storage frame 2 fixedly connected to the base platform 1, a fixing plate 3 fixedly connected to the base platform 1, a drive 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 drive motor 4, a fixing 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 standing platform 73 fixedly connected to the bottom inner surface of the water storage frame 2, a fastening bolt 74 threadedly connected to the standing platform 73, a support frame 75 fixedly connected to the bottom inner surface of the water storage frame 2, a guide wheel 76 rotatably connected to the support frame 75, the guide wheel 76 having a groove, a wire drawing die 8 placed on the standing platform 73, a guiding mechanism provided on the water storage frame 2 for guiding the wire, and a fixing mechanism provided on the guiding mechanism for fixing the wire reel.

[0029] The guiding mechanism includes a side plate 91, which is fixedly connected to one side of the fixed plate 3. A supporting curved plate 92 is fixedly connected to the water storage frame 2. A rotating platform 93 is rotatably connected to the supporting curved plate 92. Rotating frames 94 are rotatably connected to both the rotating platform 93 and the side plate 91. Torsion springs 95 are connected between the two rotating frames 94 and the rotating platform 93 and the side plate 91, respectively. Clamping wheels 96 are rotatably connected to the sides of the two rotating frames 94 that are close to each other. The clamping wheels 96 have limit grooves. Two iron blocks 97 are fixedly connected to the lower part of the rotating platform 93. The two iron blocks 97 are symmetrically distributed. A magnet 98 is fixedly connected to the supporting curved plate 92. The magnet 98 is in contact with the side of one of the iron blocks 97. A handle 99 is fixedly connected to one side of the rotating platform 93.

[0030] The fixing mechanism includes a long rod 101, which is rotatably connected to the supporting curved plate 92. A rotating gear 102 is fixedly connected to the long rod 101. A rack and pinion 103 is slidably connected to the supporting curved plate 92, and the rack and pinion 103 meshes with the rotating gear 102. A guide plate 104 is fixedly connected to one side of the rack and pinion 103, and a straight groove is opened on the guide plate 104. A lever 105 is fixedly connected to the side of the rotating platform 93 away from the handle 99. The lever 105 is located in the straight groove on the guide 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 rods 106 and the long rod 101. Two rotating balls 108 are rotatably connected to the upper part of each of the two swing rods 106.

[0031] In actual operation, first, the water storage frame 2 is filled with water. Then, the operator needs to turn the handle 99 by 90°. This rotation of the handle 99 will cause the rotating platform 93 and one of the clamping wheels 96 to rotate together. Then, the rotation of the rotating platform 93 will cause the two iron blocks 97 to rotate by 90°, so that one iron block 97 is disengaged from the magnet 98, while the other iron block 97 is in contact with the magnet 98. The rotation of the rotating platform 93 will cause the lever 105 to rotate. The rotation of the lever 105 will cause the guide plate 104 to move away from the fixed plate 3. The guide plate 104 moves horizontally, causing the rack and pinion 103 to move horizontally away from the fixed plate 3. The horizontal movement of the rack and pinion 103 causes the rotating gear 102 and the long rod 101 to rotate 90° together. The rotation of the long rod 101 by 90° causes the swing 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 and the winding reel on the rotating roller 5. Then, a portion of the wire is drawn out, passes through the drawing die 8, and a portion of the wire passes through the guide wheel 76 and is guided by the groove on the guide wheel 76. The operator then moves the handle 99 to reset, causing one of the clamping wheels 96 to reset as well. This clamps the wire between the two clamping wheels 96, with the wire positioned within the limiting groove on the clamping wheel 96. The wire is then wound onto the winding reel and tightened. Resetting the handle 99 will ultimately reset the long rod 101 and the swing rod 106. The upward swing of the swing rod 106 will limit the movement of the bead 108 against the side of the reel placed on the rotating roller 5 and the fixed roller 6. The operator then starts the drive motor 4, which will rotate the rotating roller 5. The rotation causes the winding spool placed on top to rotate as well, which in turn pulls the wire continuously through the drawing die 8 to complete the wire drawing. The two clamping wheels 96 clamp the wire and can accommodate the wire passing through the clamping wheels 96 at different angles. When the wire tilts up or down, the two clamping wheels 96 will also tilt to adapt to the angle of the wire. This ensures that the direction of the wire is uniform and unchanged after passing through the clamping wheels 96, making the wire drawing through the drawing die 8 more stable. Then, the water pump 71 draws water from the water storage frame 2 and sprays it onto the drawing die 8 through the water spray pipe 72 to cool the wire.

[0032] Example 2

[0033] Based on Example 1, such as Figure 7-9As shown, it also includes a perforation mechanism, which is mounted on the platform 73. The perforation mechanism assists in wire perforation and includes a side block 111 fixedly connected to the side of the platform 73 near the rotating roller 5. A swing piston cylinder 112 is rotatably connected to the side block 111. A torsion spring 113 connects 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, communicating with the swing piston cylinder 112. The upper part of 14 is made of silicone. A piston 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. An oblique groove is opened on the rotating groove rod 116. A toggle connecting rod 117 is fixedly connected to the rack and pinion 103. The toggle connecting rod 117 cooperates with the rotating groove rod 116. A horn tube frame 118 is fixedly connected to the side of the stand 73 away from the side block 111. The horn tube frame 118 contacts one side of the wire drawing mold 8. A rubber ring 119 is placed inside the horn tube frame 118.

[0034] When the operator rotates the handle 99 by 90°, the rack and pinion 103 moves horizontally a distance away from the fixed plate 3. Then, the rack and pinion 103 drives the actuating link 117 to move horizontally as well. This horizontal movement of the actuating link 117 causes the rotating groove rod 116 to rotate 100°. The rotation of the rotating groove rod 116 causes the swing piston cylinder 112 and piston rod 115 to rotate together. After the swing piston cylinder 112 and contact tube 114 rotate 90°, one side of the contact tube 114 contacts the side of the wire drawing die 8, and the swing piston cylinder 112 and contact tube 114 stop rotating. The continued rotation of the rotating groove rod 116 causes the torsion spring 113 to be twisted, which in turn causes the contact tube 114 to... The wire will be squeezed against the side of the wire drawing die 8. Since one end of the contact tube 114 is made of silicone, the contact tube 114 and the wire drawing die 8 will be in closer contact. Then the operator will pass one end of the wire through the rubber ring 119 and put it into the speaker tube frame 118. The rubber ring 119 will wrap around the wire, so that a sealed space is formed between the piston rod 115 and the wire. Then the piston rod 115 is pulled horizontally towards the rotating roller 5. Through the principle of atmospheric pressure, the wire is moved horizontally and passes through the wire drawing die 8. Then the handle 99 is moved to reset, which causes the swing piston cylinder 112 to swing downward to reset. Then the wire that has passed through the wire drawing die 8 is further limited and fixed. This makes it easier for the wire to pass through the die.

[0035] Example 3

[0036] Based on Example 2, such as Figure 10-12As shown, it also includes a rotating mechanism, which is disposed on the water storage frame 2. The rotating mechanism is used to rotate the wire during threading. The rotating mechanism includes a straight plate frame 121, which is fixedly connected to the bottom surface of the water storage frame 2. A rocking frame 122 is rotatably connected to the straight plate frame 121. The rocking frame 122 has round holes on both sides. Two rotating wheels 123 are rotatably connected to the rocking frame 122. A transmission gear 124 is fixedly connected to the lower part of one of the rotating wheels 123. A rotating crank 125 is rotatably connected to the lower part of the rocking frame 122. A driven gear 126 is fixedly connected to the rotating crank 125. The driven gear 126 meshes with the transmission gear 124. Two crossbars 127 are fixedly connected to the upper part of the straight plate frame 121.

[0037] Before the wire is passed through the drawing die 8, one end of the wire is passed through the round holes on both sides of the rocker frame 122. The fixed wire is then held by two rotating wheels 123. When the wire is pulled for drawing, the wire pulls the two rotating wheels 123 together. The rotation of the rotating wheels 123 drives the transmission gear 124 to rotate. The transmission gear 124 drives the rotating crank 125 to rotate through the driven gear 126. The rotating crank 125 presses against the crossbars 127 on both sides. When the rotating crank 125 presses against one of the crossbars 127... Rotating the crank 125 will tilt it, which in turn will cause the rocker frame 122 to tilt. When the crank 125 presses against another crossbar 127, the crank 125 will tilt in the opposite direction. This causes the rocker frame 122 to tilt and rock back and forth with small amplitude. Since the two rotating wheels 123 hold the wire, the two rotating wheels 123 will drive the wire to rotate back and forth with the rocker frame 122 tilting and rocking back and forth with small amplitude. When drawing copper wire, the reciprocating rotation of the wire can make the contact position between the wire and the mold constantly change, reducing stress concentration and making the wire less likely to break when drawing.
