Description

Technical Field

[0001] This utility model relates to the technical field of wire rod pulling device with positioning and clamping structure, and particularly to a wire rod pulling device with positioning and clamping structure. Background Technology

[0002] In the metal processing industry, wire rod, as a common raw material, often needs to be processed into metal wires of specific specifications. In this process, the wire rod drawing device is crucial. It is responsible for unwinding, positioning, clamping, and drawing the coiled wire rod as required, providing a foundation for subsequent processing steps such as wire drawing and cutting. As the application fields of metal products continue to expand, from steel bar manufacturing in the construction field to precision wire production in the electronics industry, the performance requirements for wire rod drawing devices are increasing. In the manufacturing of high-precision products, such as metal wires used in aerospace components, stringent standards are imposed on the positioning accuracy and clamping stability during wire rod drawing. In large-scale production scenarios, such as the processing of ordinary metal wires for construction, the device is required to have the ability to operate efficiently and continuously. Therefore, the development of wire rod drawing devices with positioning and clamping structures to meet the different needs of various industries, precision, and efficiency has become a key link in promoting the development of the metal processing industry.

[0003] Existing wire rod pulling devices with positioning and clamping structures often lack a pre-correction step with positioning blocks, causing the wire to enter the clamping assembly directly after being pulled out of the coil. Due to the initial bending, the clamping position is deviated. At the same time, most devices use a single-sided drive or single clamping plate structure. During the clamping process, the wire is easily affected by asymmetrical forces and deviates to one side. To address this, we propose a wire rod pulling device with a positioning and clamping structure. Utility Model Content

[0004] The purpose of this utility model is to provide a wire rod pulling device with a positioning clamping structure to solve the problem mentioned in the background art that the positioning block pre-correction step is often missing, causing the metal wire to directly enter the clamping assembly after being pulled out of the coil, resulting in a clamping position deviation due to initial bending. At the same time, most devices adopt a single-sided drive or single clamping plate structure, and during the clamping process, the metal wire is easily affected by asymmetrical forces and deviates to one side.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wire rod pulling device with a positioning and clamping structure, comprising a base plate, a support frame fixedly installed on the top of the base plate, a wire feeding post provided on the top right side of the support frame, a metal wire provided on the outer wall of the wire feeding post, and clamping and positioning components provided on the top and bottom of the support frame, the clamping and positioning components comprising a positioning block, a motor and a sliding rod, the motor being connected to a moving block via a bidirectional screw, and the moving block being connected to a clamping plate and a V-groove plate via a connecting plate.

[0006] As a preferred embodiment, the positioning block is fixedly installed on the bottom right side of the support frame, the outer wall of the metal wire is slidably connected to the inner wall of the positioning block, the motor is fixedly installed on the upper back of the support frame, and one end of the bidirectional screw is fixedly connected to the output end of the motor.

[0007] As a preferred embodiment, the other end of the bidirectional screw is rotatably connected to the upper right front inner wall of the support frame, the outer wall of the bidirectional screw is rotatably connected to the upper right rear inner wall of the support frame, the slide rod is fixedly installed on the upper left inner wall of the support frame, and two sets of the moving blocks are provided.

[0008] As a preferred embodiment, one set of the movable blocks is slidably connected to the outer wall of the slide rod, and another set of the movable blocks is threadedly connected to the outer wall of the bidirectional screw. The corresponding sides of the two sets of movable blocks are respectively fixedly connected to both ends of the connecting plate. The clamping plate is fixedly connected to the bottom of the connecting plate. The V-groove plate is fixedly installed on the outer wall of the clamping plate. The outer wall of the metal wire is in contact with the outer wall of the V-groove plate.

[0009] As a preferred embodiment, the top of the base plate is provided with a cutting assembly, the cutting assembly including a support plate, the support plate being fixedly installed on the top of the base plate and located on the left side of the support frame, the top of the support plate being fixedly connected to a connecting block, and the top of the connecting block being provided with a cutting groove.

[0010] As a preferred embodiment, a placement groove is provided at the middle position of the cutting groove, the outer wall of the metal wire is in contact with the inner wall of the placement groove, a hydraulic cylinder is fixedly installed on the top left side of the support frame, a cutter is fixedly connected to the lower end of the hydraulic cylinder, and the outer wall of the cutter is slidably connected to the inner wall of the cutting groove.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. Through the set clamping and positioning components, the metal wire passes through the positioning groove of the positioning block and enters the clamping and positioning components after the path is initially corrected. This can effectively eliminate the initial bending of the coiled metal wire and make the metal wire enter the clamping and positioning components in a straighter state. Then, the operator starts the motor to drive the bidirectional screw to rotate. The two sets of moving blocks move closer synchronously along the slide bar. The connecting plate pushes the clamping plate and the V-groove plate to clamp the metal wire. When the metal wire is embedded in the V-groove plate, the two inclined surfaces automatically position it to the center. The clamping accuracy of the metal wire can be ensured without manual calibration. At the same time, it is compatible with diameter fluctuations within a certain range, which improves the applicability and automation of the device.

[0013] 2. With the setting of the cutting component, when the metal wire slides on the inner wall of the placement groove, the placement groove provides precise radial positioning for it, limiting the deviation of the metal wire. When the hydraulic cylinder drives the cutter to slide down along the inner wall of the cutting groove, the cutting groove provides guidance for the vertical movement of the cutter, ensuring that the cutter moves along a fixed path. The two work together to ensure that the metal wire is cut at the preset position with small cutting position error, which can meet the requirements of high-precision processing.

[0021] 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 protection scope of the present utility model.

[0022] Please see the appendix Figure 1 - Appendix Figure 4A wire rod pulling device with a positioning and clamping structure includes a base plate 1, a support frame 2 fixedly installed on the top of the base plate 1, a wire feeding post 3 provided on the top right side of the support frame 2, a metal wire 4 provided on the outer wall of the wire feeding post 3, and clamping and positioning components 5 provided on the top and bottom of the support frame 2. The clamping and positioning components 5 include a positioning block 501, a motor 502 and a sliding rod 508. The motor 502 is connected to a moving block 504 through a bidirectional screw 503. The moving block 504 is connected to a clamping plate 506 and a V-groove plate 507 through a connecting plate 505. The positioning block 501 is fixedly installed on the bottom right side of the support frame 2. The outer wall of the metal wire 4 is slidably connected to the inner wall of the positioning block 501. The motor 502 is fixedly installed on the upper back of the support frame 2. One end of the bidirectional screw 503 is fixedly connected to the output end of the motor 502.

[0023] The wire feeding post 3 is used to store the coiled metal wire 4 as the source of the metal wire 4. During operation, the metal wire 4 is gradually released from its outer wall, similar to a wire feeding frame, so that the metal wire 4 is unfolded in an orderly manner. A disc is rotatably connected to the bottom of the wire feeding post 3.

[0024] The other end of the bidirectional screw 503 is rotatably connected to the upper right front inner wall of the support frame 2, and the outer wall of the bidirectional screw 503 is rotatably connected to the upper right rear inner wall of the support frame 2. The slide rod 508 is fixedly installed on the upper left inner wall of the support frame 2. Two sets of moving blocks 504 are provided. One set of moving blocks 504 is slidably connected to the outer wall of the slide rod 508, and the other set of moving blocks 504 is threadedly connected to the outer wall of the bidirectional screw 503. The corresponding sides of the two sets of moving blocks 504 are fixedly connected to the two ends of the connecting plate 505. The clamping plate 506 is fixedly connected to the bottom of the connecting plate 505. The V-groove plate 507 is fixedly installed on the outer wall of the clamping plate 506. The outer wall of the metal wire 4 is in contact with the outer wall of the V-groove plate 507.

[0025] The top of the support frame 2 has a hollowed-out section to provide moving space for the clamping plate 506 and the V-groove plate 507. The outer wall of the positioning block 501 has a positioning groove through which the metal wire 4 passes.

[0026] Specifically, through the clamping and positioning component 5, the metal wire 4 passes through the positioning groove of the positioning block 501, and enters the clamping and positioning component 5 after the path is initially corrected, eliminating the initial bending of the coiled metal wire 4. The motor 502 is started to drive the bidirectional screw 503 to rotate, and the two sets of moving blocks 504 move closer to each other along the slide bar 508. The connecting plate 505 pushes the clamping plate 506 and the V-shaped groove plate 507 to clamp the metal wire 4. When the metal wire 4 is embedded in the V-shaped groove plate 507, the two inclined surfaces are automatically positioned to the center to ensure clamping accuracy, accommodate certain diameter fluctuations, and improve the applicability and automation of the device.

[0027] Please see the appendix Figure 1 Appendix Figure 5 and appendix Figure 6 A cutting assembly 6 is provided on the top of the base plate 1. The cutting assembly 6 includes a support plate 601, which is fixedly installed on the top of the base plate 1 and located on the left side of the support frame 2. A connecting block 602 is fixedly connected to the top of the support plate 601. A cutting groove 603 is provided on the top of the connecting block 602. A placement groove 604 is provided in the middle of the cutting groove 603. The outer wall of the metal wire 4 is in contact with the inner wall of the placement groove 604. A hydraulic cylinder 605 is fixedly installed on the top left side of the support frame 2. A cutter 606 is fixedly connected to the lower end of the hydraulic cylinder 605. The outer wall of the cutter 606 is slidably connected to the inner wall of the cutting groove 603.

[0028] The hydraulic cylinder 605 serves as the power source for the cutting action. It drives the piston through hydraulic oil, converting hydraulic energy into the linear motion of the cutter 606. The outer wall of the piston rod is slidably connected to the top inner wall of the support frame 2.

[0029] Specifically, through the cutting component 6, when the metal wire 4 slides on the inner wall of the placement groove 604, the placement groove 604 provides precise radial positioning and limits the offset. When the hydraulic cylinder 605 drives the cutter 606 to slide down along the inner wall of the cutting groove 603, the cutting groove 603 guides the vertical movement of the cutter 606. The two work together to ensure that the metal wire 4 is cut at the preset position with small error, meeting the requirements of high-precision processing.

[0030] The working principle of this utility model is as follows: This utility model is a wire rod pulling device with a positioning and clamping structure. First, the operator places a coiled metal wire 4 onto the wire feeding post 3, with the end of the metal wire 4 extending from the outer wall of the wire feeding post 3. The end of the metal wire 4 is then passed through the positioning groove of the positioning block 501, and then sequentially introduced into the V-shaped groove plate 507 and the placement groove 604 of the clamping and positioning assembly 5, ensuring that the path of the metal wire 4 is aligned with the center of each assembly. Then, the operator starts the motor 502, whose output end drives the bidirectional screw 503 to rotate. The rotation of the bidirectional screw 503 drives two sets of moving blocks 504 to move towards each other. The two sets of moving blocks 504 then push the two sets of clamping plates 506 and the two sets of V-shaped groove plates 507 to close together through the two sets of connecting plates 505. The metal wire 4 will be embedded in the V-grooves of the two sets of V-groove plates 507. The inclined surfaces on both sides will automatically position it to the center and clamp it, completing precise clamping. After the clamping is stable, the operator will drive the mechanism to pull the metal wire 4. The disc at the bottom of the wire feeding column 3 will rotate accordingly, and the metal wire 4 will be gradually released from the coil. At this time, the metal wire 4 will slide on the inner wall of the placement groove 604. The placement groove 604 provides radial positioning to limit its deviation. At the same time, the cutter 606 is waiting at the top of the cutting groove 603. When the metal wire 4 is pulled to the preset length, the operator will start the hydraulic cylinder 605. The hydraulic oil will push the piston rod to drive the cutter 606 to slide vertically down the inner wall of the cutting groove 603. The cutter 606 will cooperate with the placement groove 604 to cut the metal wire 4 at the preset position.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
