Description

Technical Field

[0001] The utility model relates to the technical field of four-pin machining, and specifically relates to a four-pin twisting and cutting equipment. Background Technique

[0002] A four-pin usually refers to a needle-shaped component with four edges or corners, usually made of copper material. In the production of automotive connectors, twisting and cutting can make the four-pin meet specific shape and size requirements to accurately match the design specifications of the connector, ensuring tight connection and good contact with other components. Therefore, a twisting and cutting equipment is required.

[0003] A Chinese patent with the publication number CN217848602U discloses a four-pin twisting and cutting structure, a traction chute, in which four-pin workpieces are placed. A stamping groove is formed on the upper surface of the bearing plate, and a groove is formed on one side of the upper surface of the bearing plate. A guide seat is installed inside the groove, and a limiting slide rail is installed on one side inside the groove. Through the setting of the transmission component, the toothed slider makes a reciprocating up and down movement. Under the meshing with the semi-gear, the rotating bushing drives the inner core to rotate, and then the four-pin workpiece inside the inner core rotates 90 degrees. Since the positioning pressure block has fixed the strip, the four-pin workpiece is directly separated from the strip by the torsion generated by the inner core and the positioning pressure block, without damaging the mold cutting edge.

[0004] However, there are still some problems in the above-mentioned twisting and cutting structure. In practical applications, inaccurate twisting angles of the four-pins will directly affect the matching accuracy between the connector and other components. In the prior art, the twisting angle cannot be accurately controlled, reducing the consistency and reliability of the product and affecting the stability of electrical signal transmission. Therefore, a four-pin twisting and cutting equipment is proposed for the above problems. Content of the Utility Model

[0005] In order to make up for the deficiencies of the prior art and solve the problems proposed in the background technique, the utility model proposes a four-pin twisting and cutting equipment.

Detailed implementation manners

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-4As shown in the figure, a four-pin twisting and cutting device includes a workbench 1. On one side of the workbench 1, a bracket 2 is installed. At the top of the bracket 2, an arc-shaped plate 3 is installed. Inside the arc-shaped plate 3, an arc-shaped groove 4 is opened. Inside one end of the arc-shaped groove 4, a sliding block 5 is slidably installed. On one side of the sliding block 5, an electrode plate 6 is installed. On the top side of the sliding block 5, a driving motor 7 is installed. At the output end of the driving motor 7, a gear 8 is installed. On the outer wall of the arc-shaped plate 3, a rack 9 is installed, and the gear 8 meshes with the rack 9. At the bottom side of one end of the sliding block 5, a connecting rod 10 is installed. At the bottom end of the connecting rod 10, a connecting block 11 is fixedly connected. Inside the connecting block 11, a through hole 12 is opened. Inside the other end of the arc-shaped groove 4, a slider 13 is slidably installed. On one side of the slider 13, an electrode piece 14 is installed. Inside the slider 13, a locking screw 15 is rotatably installed. On one side of the workbench 1, a control panel 33 is installed; during operation, in practical applications, inaccurate twisting angles of the four pins will directly affect the fitting accuracy between the connector and other components. In the prior art, the twisting angle cannot be accurately controlled, reducing the consistency and reliability of the product and affecting the stability of electrical signal transmission. First, according to the required twisting angle of the four pins, the slider 13 is driven to drive the electrode piece 14 to slide along the arc-shaped groove 4 to a suitable position, and then it is fixed by the locking screw 15. Subsequently, the driving motor 7 is started through the control panel 33. The driving motor 7 drives the gear 8 to rotate. Since the gear 8 meshes with the rack 9, the rotation of the gear 8 will drive the sliding block 5 to drive the electrode plate 6 to slide in the arc-shaped groove 4. When the sliding block 5 moves, the connecting rod 10 and the connecting block 11 drive one end of the copper wire to move, and the twisting of the copper wire is realized with the cooperation of the arc-shaped block 24. When the electrode plate 6 comes into contact with the electrode piece 14, an electrical signal will be generated and transmitted to the control panel 33. The control panel 33 controls the driving motor 7 to stop rotating, realizing the accurate presetting of the twisting angle of the four pins, ensuring the consistency and reliability of the product, and improving the transmission effect of electrical signals.

[0024] Please refer to Figures 1-5 As shown in the figure, on the other side of one end of the workbench 1, a wire unwinding motor 30 is installed. At the output end of the wire unwinding motor 30, a rotating shaft 31 is installed. On the outer wall of the rotating shaft 31, a wire unwinding roller 32 is installed. On the outer wall of the wire unwinding roller 32, a copper wire is assembled.

[0025] A support base 16 is installed on the top side of the workbench 1. A placement groove 17 is formed inside the support base 16. A tool groove 18 is formed through the placement groove 17 at one end of the support base 16. A support frame 25 is installed in the middle of the top side of the workbench 1. A telescopic rod 26 is installed on the top side of the support frame 25. Guide rods 27 are slidably installed through the inner parts of the two ends of the top side of the support frame 25. The bottom ends of the guide rods 27 and the acting ends of the telescopic rod 26 are fixedly connected to form a fixed frame 28. A number of rollers 29 are installed inside the fixed frame 28 through pin shaft cooperation. An L-shaped frame 19 is installed at the edge of one end of the top side of the workbench 1. A cylinder 20 is installed on the top side of the L-shaped frame 19. An installation frame 21 is installed at the acting end of the cylinder 20. A cutting motor 22 is installed on one side of the installation frame 21. A cutting tool 23 is installed at the output end of the cutting motor 22. The cutting tool 23 is located directly above the tool groove 18. An arc-shaped block 24 is installed on one side of the workbench 1 and on one side of the support base 16. During work, in the production of automotive connectors, by twisting and cutting the material, the four-pin needles can meet specific shape and size requirements to accurately match the design specifications of the connectors, ensuring tight connection and good contact with other components. Therefore, a twisting and cutting equipment is needed. Start the unwinding motor 30. The unwinding motor 30 drives the rotating shaft 31 to rotate, so that the unwinding roller 32 installed on the outer wall of the rotating shaft 31 rotates, realizing the automatic unwinding of the copper wire material. The copper wire passes through the placement groove 17 of the support base 16 from the output end of the unwinding roller 32, and then one end of it passes through the through hole 12 of the connecting block 11. Before the twisting process, the telescopic rod 26 pushes the fixed frame 28 to move downward in cooperation with the guide rods 27. The rollers 29 in the fixed frame 28 press on the copper wire to guide and firmly fix the copper wire to prevent it from moving or shaking during the processing. After the copper wire is twisted to form the four-pin needles, the cylinder 20 pushes the installation frame 21 to move downward, and at the same time the cutting motor 22 drives the cutting tool 23 to rotate. The cutting tool 23 cuts the four-pin needles. The cutting tool 23 is exactly located directly above the tool groove 18 to ensure the accuracy and stability of the cutting. The arc-shaped block 24 plays an auxiliary supporting and guiding role for the copper wire during the twisting process, ensuring the stability and precision of the processing.

[0026] Working principle: First, according to the required twisting angle of the four-pin needles, drive the electrode plate 14 with the slider 13 to slide along the arc-shaped groove 4 to a suitable position, and then fix it with the locking screw 15.

[0027] Start the unwinding motor 30. The unwinding motor 30 drives the rotating shaft 31 to rotate, thereby causing the unwinding roller 32 mounted on the outer wall of the rotating shaft 31 to rotate, realizing the automatic unwinding of the copper wire material. The copper wire passes through the placement groove 17 of the support base 16 from the output end of the unwinding roller 32, and then one end of it penetrates through the through hole 12 of the connecting block 11. Before the twisting process, the telescopic rod 26 pushes the fixing frame 28 to move downward in cooperation with the guide rod 27. The roller 29 in the fixing frame 28 presses on the copper wire to guide and firmly fix the copper wire, preventing it from moving or shaking during the processing;

[0028] Subsequently, start the driving motor 7 through the control panel 33. The driving motor 7 drives the gear 8 to rotate. Since the gear 8 meshes with the rack 9, the rotation of the gear 8 will drive the sliding block 5 to drive the electrode plate 6 to slide in the arc-shaped groove 4. When the sliding block 5 moves, it causes the connecting rod 10 and the connecting block 11 to drive one end of the copper wire to move, and the twisting of the copper wire is realized in cooperation with the arc-shaped block 24. When the electrode plate 6 contacts the electrode piece 14, an electrical signal will be generated and transmitted to the control panel 33. The control panel 33 controls the driving motor 7 to stop rotating, realizing the accurate preset twisting angle of the four-pin needle, which can ensure the consistency and reliability of the product and improve the transmission effect of the electrical signal;

[0029] After the copper wire is twisted to form a four-pin needle, the air cylinder 20 pushes the mounting frame 21 to move downward, and at the same time, the cutting motor 22 drives the cutter 23 to rotate. The cutter 23 cuts the four-pin needle. The cutter 23 is exactly above the knife groove 18 to ensure the accuracy and stability of the cutting. The arc-shaped block 24 plays an auxiliary supporting and guiding role for the copper wire during the twisting process, ensuring the stability and precision of the processing.
