Description

Technical Field

[0001] This utility model relates to the field of copper alloy strip processing technology, specifically a copper alloy strip drawing device. Background Technology

[0002] Copper alloy strips are commonly used as battery connectors. The production and processing of copper alloy strips requires applying tension to the strip through a mold, causing it to undergo plastic deformation through the mold holes, thereby changing the cross-sectional dimensions and improving performance. Therefore, a drawing device is required.

[0003] A Chinese patent with authorization announcement number CN117259493A discloses a copper busbar drawing and straightening device, including two support plates, which are welded to both sides of the upper surface of the workbench. Two first electric push rods are also included, with one end welded to one surface of each of the two support plates and the other end of each rod welded to a connecting plate. Each connecting plate has a placement groove on one surface, and several connecting shafts are embedded inside each groove. Traction rollers are embedded on the circumferential side of each connecting shaft, and the traction rollers rotate in conjunction with the circumferential side of the connecting shafts. Through the connecting plate and traction roller structure, the copper busbar can be moved forward in the same position during the drawing process, avoiding lateral bending of the copper busbar during drawing, thus improving the practicality and straightening efficiency of the device.

[0004] However, the above-mentioned equipment still has some problems. In practical applications, it cannot position the drawing length of the copper alloy strip, which will lead to inaccurate drawing length, affect product consistency, and thus prevent continuous processing of the copper alloy strip. Therefore, a copper alloy strip drawing device is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background technology, this utility model proposes a copper alloy strip drawing device.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A copper alloy strip drawing device of this utility model includes a worktable. A rectangular groove is formed inside one end of the worktable. A mounting frame is slidably installed inside the rectangular groove. A positioning plate is installed on one side of the top of the mounting frame. A mounting plate is installed on one side of the mounting frame. An electrode plate is installed on one side of the mounting plate. One side of the electrode plate and one side of the positioning plate are on the same horizontal line. A slide rail is formed inside the edge of the worktable. A sliding block is slidably installed inside the slide rail. A locking screw is rotatably installed through the sliding block. One end of the locking screw is connected to the slide rail. The inner walls of the bottom sides are pressed together. A connecting plate is installed on one side of the sliding block, and an electrode plate is installed on one side of the connecting plate. Several scale lines are equidistantly engraved on the top side of the worktable, located on one side of the slide rail. An indicator needle is mounted on the other side of the sliding block, with the tip of the indicator needle on the same horizontal line as one side of the electrode plate. An indicator light is installed on one side of the mounting frame. The position of the sliding block is adjusted according to the required drawing length so that the indicator needle points to the corresponding scale line, thereby determining the drawing length. When the copper alloy strip is drawn to the point where the electrode plate contacts the electrode plate, the external cutting component can automatically cut the copper alloy strip through the circuit connection, greatly improving the accuracy and efficiency of the drawing operation.

[0007] Preferably, a first motor is installed on one side of the workbench, and a threaded rod is installed at the output end of the first motor. A screw hole and a positioning hole are respectively opened through the bottom end of the mounting frame. One end of the threaded rod passes through the screw hole and is rotatably installed inside one side of the rectangular groove. A sliding positioning hole passes through the two sides of the rectangular groove and a guide rod is fixedly installed. When the first motor is started, the threaded rod rotates. Due to the positioning effect of the guide rod, the mounting frame will move in a straight line along the rectangular groove, thereby realizing the drawing operation of the copper alloy strip.

[0008] Preferably, a cylinder is installed on the top side of the mounting frame, and a fixing plate is installed on the actuating end of the cylinder. Friction pads are installed on the bottom side of the fixing plate and inside the top of the mounting frame. Before the drawing operation, one end of the copper alloy strip is placed on the top of the mounting frame and attached to one side of the positioning plate. The cylinder is activated, pushing the fixing plate downward, so that the friction pads are tightly attached to the copper alloy strip, thereby firmly fixing one end of the copper alloy strip inside the mounting frame. The friction pads increase the friction between the fixing plate and the copper alloy strip, effectively preventing the copper alloy strip from sliding or falling off during the drawing process, improving the stability during the drawing process, and ensuring that the drawing operation can be carried out smoothly.

[0009] Preferably, two fixed plates are symmetrically installed on the other end of the top side of the workbench. A telescopic rod is installed on one side of each fixed plate, and a support frame is installed on the working end of each telescopic rod. Three feeding rollers are installed equidistantly inside the support frame through pin engagement. The distance between the feeding rollers can be adjusted by the telescopic rod to accommodate copper alloy strips of different widths, so that the copper alloy strip can be fed smoothly and stably during the drawing process, reducing friction and resistance during the feeding process.

[0010] Preferably, one end of the workbench has an upward-opening groove. A connecting cavity is installed on one side of the groove. A rotating shaft is rotatably mounted through one side of the connecting cavity. An installation ring is installed at one end of the rotating shaft. Four support columns are equidistantly installed on the outer side of the installation ring. A connecting block is installed at one end of each support column. A shaping groove with different dimensions is opened inside each connecting block. A worm gear is installed at the other end of the rotating shaft. A second motor is installed inside one side of the connecting cavity. A rotating shaft is installed at the output end of the second motor. A worm is installed on the outer side of the rotating shaft. The worm gear and the worm mesh with each other. When the shaping groove needs to be changed according to the drawing size of the copper alloy strip, the second motor starts, driving the rotating shaft to rotate through the worm gear transmission, thereby rotating the installation ring and rotating the shaping groove of the appropriate size to the working position. This enables the rapid and accurate alternation of the shaping groove according to different drawing sizes, without the need to frequently replace the entire shaping component, greatly improving the efficiency of the drawing operation.

[0011] Preferably, a control panel is installed on one side of the workbench. The electrode plate, electrode sheet, indicator light, and first motor are connected to the power supply in a circuit. The indicator light is connected to the control panel via a signal line. The control panel is used to control the operation of the first motor. The control panel is electrically connected to other electrical components inside the device. The entire drawing device can be centrally controlled through the control panel, including starting and stopping the first motor, adjusting the drawing speed, and monitoring the drawing length, thereby improving the automation level of the device.

[0012] The advantages of this utility model are:

[0013] 1. In this utility model, the locking screw is loosened, the sliding block is slid to allow the indicator to align with the target length value on the scale line, and the screw is tightened to fix it. At this time, the distance between the electrode plate and the positioning plate is the set pulling length. During pulling, the copper alloy strip is pulled until the electrode plate contacts the electrode plate to form a complete circuit. The indicator light illuminates and transmits the signal to the control panel. The control panel controls the first motor to stop rotating and simultaneously triggers the external cutting component to cut the copper alloy strip, thereby achieving precise control of the pulling length and improving the accuracy and efficiency of the operation.

[0014] 2. The output end of the second motor of this utility model drives the rotating shaft to rotate, the worm gear to rotate, the worm gear drives the worm wheel to rotate, and then the rotating shaft to rotate. The rotating shaft drives the mounting ring to rotate, and the four support columns installed at equal intervals on the outside of the mounting ring will rotate accordingly. The shaping grooves of different sizes inside the connecting block of one end of the support column are rotated to the working position in sequence. This realizes the rapid and accurate alternation of the shaping grooves according to different drawing dimensions, without the need to frequently replace the entire shaping component, thus improving the efficiency of the drawing operation.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figure 1-3 As shown, a copper alloy strip drawing device includes a worktable 1. A rectangular groove 2 is formed inside one end of the worktable 1. A mounting frame 201 is slidably installed inside the rectangular groove 2. A positioning plate 202 is installed on one side of the top of the mounting frame 201. A mounting plate 203 is installed on one side of the mounting frame 201. An electrode plate 204 is installed on one side of the mounting plate 203. One side of the electrode plate 204 and one side of the positioning plate 202 are on the same horizontal line. A slide rail 205 is formed inside the edge of the worktable 1. A sliding block 206 is slidably installed inside the slide rail 205. A locking screw 207 is rotatably mounted inside the sliding block 206. One end of the locking screw 207 abuts against the bottom inner wall of the slide rail 205. A connecting plate 208 is mounted on one side of the sliding block 206, and an electrode plate 209 is mounted on one side of the connecting plate 208. Several scale lines 210 are equidistantly engraved on the top side of the worktable 1, located on one side of the slide rail 205. An indicator needle 211 is mounted on the other side of the sliding block 206. The tip of the indicator needle 211 is on the same horizontal line as one side of the electrode plate 209. An indicator light 212 is mounted on one side of the mounting frame 201.

[0024] A first motor 3 is installed on one side of the workbench 1. A threaded rod 301 is installed at the output end of the first motor 3. A screw hole and a positioning hole are respectively opened through the bottom end of the mounting frame 201. One end of the threaded rod 301 passes through the screw hole and is rotatably installed inside one side of the rectangular groove 2. A sliding positioning hole passes through the two sides of the rectangular groove 2 and a guide rod 302 is fixedly installed.

[0025] A control panel 6 is installed on one side of the workbench 1. The electrode plate 204, electrode sheet 209, indicator light 212, and first motor 3 are connected to the power supply as a circuit. The indicator light 212 is connected to the control panel 6 through a signal line. The control panel 6 is used to control the operation of the first motor 3. The control panel 6 is electrically connected to other electrical components inside the device. During operation, in practical applications, the drawing length of the copper alloy strip cannot be positioned, which will lead to inaccurate drawing length, affect product consistency, and thus prevent continuous processing of the copper alloy strip. According to the process requirements, the drawing length of the copper alloy strip is determined by loosening the locking screw 207, sliding the block 206 along the slide rail 205, aligning the indicator needle 211 with the target length value on the scale line 210, tightening the locking screw 207, and fixing the sliding block 206 on the slide rail 205. At this time, the distance between the electrode sheet 209 and the positioning plate 202 is the set drawing length.

[0026] Start the first motor 3. The output end of the first motor 3 drives the threaded rod 301 to rotate. Under the positioning action of the guide rod 302, the mounting frame 201 will move in a straight line along the rectangular groove 2, thereby realizing the pulling operation of the copper alloy strip fixed on the mounting frame 201.

[0027] During the drawing process, when the copper alloy strip is drawn to the point where the electrode sheet 209 contacts the electrode plate 204, a complete circuit is formed, and the indicator light 212 lights up. The indicator light 212 transmits the signal to the control panel 6 through the signal line. After receiving the signal, the control panel 6 controls the first motor 3 to stop moving. At the same time, the external cutting component can cut the copper alloy strip, realizing precise control of the drawing length and greatly improving the accuracy and efficiency of the drawing operation.

[0028] Please see Figure 1 , 2 As shown in Figures 4 and 5, a cylinder 303 is installed on the top side of the mounting frame 201, and a fixing plate 304 is installed on the working end of the cylinder 303. Friction pads 305 are installed on the bottom side of the fixing plate 304 and inside the top of the mounting frame 201.

[0029] Two fixed plates 4 are symmetrically installed on the other side of the top side of the workbench 1. A telescopic rod 401 is installed on one side of each fixed plate 4. A support frame 402 is installed on the working end of each telescopic rod 401. Three feeding rollers 403 are installed at equal intervals inside the support frame 402 through a pin engagement.

[0030] The workbench 1 has an upward-opening groove 5 at one end. A connecting cavity 501 is installed on one side of the groove 5. A rotating shaft 502 is rotatably mounted through one side of the connecting cavity 501. An mounting ring 503 is installed at one end of the rotating shaft 502. Four support columns 504 are equidistantly installed on the outer side of the mounting ring 503. A connecting block 505 is installed at one end of each support column 504. A shaping groove 506 is opened inside each connecting block 505. The dimensions of the shaping grooves 506 are all different. A worm gear 507 is installed at the other end of the rotating shaft 502. A second motor 508 is installed inside one side of the connecting cavity 501. A rotating shaft 509 is installed at the output end of the second motor 508. A worm gear is installed on the outer side of the rotating shaft 509. 510, the worm gear 507 and the worm 510 mesh with each other; during operation, in the production and processing of copper alloy strip, it is necessary to apply tension to the copper alloy strip through the mold to make it plastically deform through the mold hole, thereby changing the cross-sectional size and improving the performance. Therefore, a drawing device is required. Before the copper alloy strip drawing operation, one end of the copper alloy strip is placed on the top of the mounting frame 201 and made to fit against one side of the positioning plate 202. At this time, the cylinder 303 is started. The action end of the cylinder 303 pushes the fixed clamping plate 304 downward. The friction pad 305 fits tightly against the copper alloy strip. The increased friction force is used to firmly fix one end of the copper alloy strip inside the mounting frame 201 to prevent the copper alloy strip from sliding or falling off during the drawing process and to ensure the stability of the subsequent drawing operation.

[0031] According to the width of the copper alloy strip to be drawn, the telescopic rod 401 is adjusted to change the distance between the feeding rollers 403 so as to match the width of the copper alloy strip. During the drawing process, the feeding rollers 403 play a role in stable and smooth feeding, effectively reducing friction and resistance during the feeding process, and ensuring that the copper alloy strip can smoothly enter the drawing process.

[0032] When the shaping slot 506 needs to be changed according to the drawing size of the copper alloy strip, the second motor 508 is started. The output end of the second motor 508 drives the rotating shaft 509 to rotate, and the worm 510 rotates accordingly. Since the worm wheel 507 and the worm 510 mesh with each other, the worm 510 drives the worm wheel 507 to rotate, which in turn causes the rotating shaft 502 to rotate. The rotating shaft 502 drives the mounting ring 503 to rotate, and the four support columns 504 installed at equal intervals on the outside of the mounting ring 503 will rotate accordingly. The shaping slots 506 of different sizes inside the connecting block 505 at one end of the support column 504 are rotated to the working position in sequence. This realizes the rapid and accurate alternation of the shaping slots 506 according to different drawing sizes, without the need to frequently replace the entire shaping component, thus improving the efficiency of the drawing operation. The first motor 3 and the second motor 508 are both servo motors.

[0033] Working principle: Determine the drawing length of the copper alloy strip according to the process requirements, loosen the locking screw 207, slide the block 206 along the slide rail 205, so that the indicator needle 211 is aligned with the target length value on the scale line 210, tighten the locking screw 207, and fix the sliding block 206 on the slide rail 205. At this time, the distance between the electrode plate 209 and the positioning plate 202 is the set drawing length.

[0034] Before performing the copper alloy strip drawing operation, place one end of the copper alloy strip on the top of the mounting frame 201 so that it is in contact with one side of the positioning plate 202. At this time, start the cylinder 303. The action end of the cylinder 303 pushes the fixing clamp 304 downward. The friction pad 305 is in close contact with the copper alloy strip. The increased friction force is used to firmly fix one end of the copper alloy strip inside the mounting frame 201 to prevent the copper alloy strip from sliding or falling off during the drawing process, and to ensure the stability of the subsequent drawing operation.

[0035] According to the width of the copper alloy strip to be drawn, the telescopic rod 401 is adjusted to change the distance between the feeding rollers 403 so as to match the width of the copper alloy strip. During the drawing process, the feeding rollers 403 play a role in stable and smooth feeding, effectively reducing friction and resistance during the feeding process, and ensuring that the copper alloy strip can smoothly enter the drawing process.

[0036] Start the first motor 3. The output end of the first motor 3 drives the threaded rod 301 to rotate. Under the positioning action of the guide rod 302, the mounting frame 201 will move in a straight line along the rectangular groove 2, thereby realizing the pulling operation of the copper alloy strip fixed on the mounting frame 201.

[0037] During the drawing process, when the copper alloy strip is drawn to the point where the electrode sheet 209 contacts the electrode plate 204, a complete circuit is formed, and the indicator light 212 lights up. The indicator light 212 transmits the signal to the control panel 6 through the signal line. After receiving the signal, the control panel 6 controls the first motor 3 to stop moving. At the same time, the external cutting component can cut the copper alloy strip, realizing precise control of the drawing length and greatly improving the accuracy and efficiency of the drawing operation.

[0038] When the shaping slot 506 needs to be changed according to the drawing size of the copper alloy strip, the second motor 508 is started. The output end of the second motor 508 drives the rotating shaft 509 to rotate, and the worm 510 rotates accordingly. Since the worm wheel 507 and the worm 510 mesh with each other, the worm 510 drives the worm wheel 507 to rotate, which in turn causes the rotating shaft 502 to rotate. The rotating shaft 502 drives the mounting ring 503 to rotate, and the four support columns 504 installed at equal intervals on the outside of the mounting ring 503 will rotate accordingly. The shaping slots 506 of different sizes inside the connecting block 505 at one end of the support column 504 are rotated to the working position in sequence. This realizes the rapid and accurate alternation of the shaping slots 506 according to different drawing sizes, without the need to frequently replace the entire shaping component, thus improving the efficiency of the drawing operation. The first motor 3 and the second motor 508 are both servo motors.
