Description

Technical Field

[0001] The invention relates to the technical field of terminal stamping dies, in particular to a stamping die for wire harness power terminal stamping equipment. Background Art

[0002] As electronic components continue to emerge, the electrical performance requirements for wiring harnesses are becoming higher and higher. Wire harness terminals play an extremely important role in wiring harnesses and the entire electrical system. Wire harness terminals refer to an electronic component that connects the wires in the wire harness. They are also called wire harness terminals. They are usually stamped from metal sheets. After the terminals are fixedly connected to the ends of the wire harnesses, they are inserted into the electronic components to electrically connect the electronic components to the wire harnesses.

[0003] The raw material of the wiring harness terminal is generally a metal coil. During production, the metal coil is first placed on the stamping equipment for continuous stamping. After the shape of the terminal is stamped out, the material with the stamped shape is processed into a formed terminal. At present, after the stamping die has stamped the metal material many times, metal debris will remain on the surface of the stamping die. If it is not cleaned in time, the metal debris will cause the surface of the stamped part to be uneven and even affect the service life of the stamping die. The staff needs to clean and maintain the stamping die at regular intervals, and the stamping operation of the terminal needs to be stopped during the maintenance phase, which makes it difficult for the stamping equipment to perform continuous stamping operations.

[0004] On the other hand, a patent with the search announcement number CN111922177B discloses a wire harness terminal stamping and forming processing equipment and a forming and processing technology. The device can improve the continuity and work efficiency of production, and at the same time ensure that the shape of the terminal is not prone to errors during the production process. However, the device is difficult to avoid the problem of stamping waste jumping up. During the stamping operation, due to insufficient material rigidity, stamping vibration or mold magnetization, the waste that falls off during stamping will jump out of the mold at the moment the upper and lower molds are separated, which not only affects the staff's collection of the remaining materials, but also some of the jumping waste will fall on the mold, affecting the next stamping operation of the mold. To this end, we provide a stamping die for a wire harness terminal stamping equipment to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to make up for the deficiencies of the prior art and provide a stamping die for a wiring harness electrical terminal stamping device, comprising a base, a material receiving and releasing assembly being provided on one side of the base, the material receiving and releasing assembly comprising a support frame three fixed on the base, a limiting block being fixed on a side of the support frame three away from the base, a pressure die being fixed on the inner wall of the limiting block, a rotation mechanism being provided inside the base, the rotation mechanism comprising a rotating tube, the rotating tube being rotatably connected to the base, a square plate being fixed to the middle part of the rotating tube, stamping mechanisms being provided on both sides of the square plate, the stamping mechanism comprising a stamping die, and the stamping die being adapted to the pressure die.

[0008] Before the stamping operation, the raw material metal strip is installed at the output end of the raw material unwinder, and then one end of the metal strip is passed through the bottom of the limit block and fits on the outer surface of the limit block, and then one end of the metal strip is installed on the finished product unwinder. During stamping, the metal strip is moved by controlling the raw material unwinder and the finished product unwinder, and the stamping die cooperates with the pressure die to continuously stamp the metal strip. Two baffle plates are set to limit the metal to prevent the metal strip from shifting during movement. The waste generated during stamping will fall below through the discharge pipe, making it convenient for the staff to collect the waste.

[0009] The stamping mechanism also includes four limit rods fixed on the square plate, a movable frame is fixed on one side of the stamping die close to the square plate, the four limit rods are slidably connected to the movable frame, and semi-annular rails are fixed on both sides of the movable frame. When the semi-annular rail on the left side of the rotating tube and the semi-annular rail on the right side of the rotating tube are closed, a full-annular rail is formed, and the axis center line of the full-annular rail coincides with the axis center line of the rotating tube.

[0010] The rotation mechanism also includes a press fixed on the right side of the base, a U-shaped plate is fixed on the telescopic end of the press, and the U-shaped plate is slidably connected to the inner bottom wall of the base, two connecting frames are fixed above the U-shaped plate, and the inner walls of the two connecting frames are fixed with toggle sliders, and the two toggle sliders are respectively slidably connected to the two semi-annular rails close to the side of the limit block. When stamping, the press is controlled to drive the two toggle sliders on the U-shaped plate to move, and the two toggle sliders will respectively toggle the two semi-annular rails close to the side of the pressure die, so that the movable frame drives the stamping die to approach the pressure die, and the stamping die cooperates with the pressure die to stamp the raw material.

[0011] A gear 1 is fixed to the outer surface of the rotating tube, a motor is fixed to the outer surface of the base, a gear 2 is fixed to the output end of the motor, the gear 2 is meshed with the gear 1, a support frame 1 is fixed to the right side of the base, a high-pressure air gun is installed on the outer surface of the support frame 1, two limit sliders are fixed on the top of the base, the two limit sliders are respectively slidably connected to the two semi-annular rails on the side away from the limit block, when the two stamping dies need to be rotated, the semi-annular rails on the left and right sides of the rotating tube are closed first, the motor is controlled to drive the gear 2 to rotate, the rotation of the gear 2 drives the rotating tube to rotate 180 degrees through the gear 1, so that the stamping dies on the left and right sides of the square plate are rotated.

[0012] The stamping mechanism also includes an extrusion frame, which is slidably connected to the outer surface of the stamping die, and four sliding rods 1 are fixed to the outer surface of the extrusion frame, and four fixed blocks are fixed to the outer surface of the stamping die, and the four fixed blocks are respectively slidably connected to the four sliding rods 1, and the outer surfaces of the four sliding rods 1 are each sleeved with a telescopic spring 1, one end of the four telescopic springs 1 is fixed to the extrusion frame, and the other ends of the four telescopic springs 1 are respectively fixed to the four fixed blocks. When the stamping die approaches the pressure-bearing die for stamping operation, the extrusion frame will first press the raw material to prevent the raw material from sliding sideways during the stamping process. After the stamping die is moved out of the pressure-bearing die, the extrusion frame is reset by the spring pressure of the four telescopic springs 1.

[0013] A movable plate is fixed on the outer surface of the diverter box, and two sliding bars are fixed on the side of the stamping die close to the movable plate, and the two sliding bars are slidably connected to the movable plate, and the two sliding bars are fixed with baffles at one end away from the stamping die, and the outer surfaces of the two sliding bars are sleeved with telescopic springs two, and the two telescopic springs two are fixedly connected between the movable plate and the stamping die, and a wedge plate one is fixed on the bottom surface of the movable plate. When the movable frame drives the stamping die to approach the pressure die, the movement of the stamping die will push the movable plate to move through the baffle, so that the five jacking tubes move with the stamping die.

[0014] The inner wall of the movable frame is fixed with an extrusion roller, and a limiting assembly is arranged under the extrusion roller, and the limiting assembly includes an inclined pressure frame and a fixed plate, and the inclined pressure frame corresponds to the position of the extrusion roller, and a wedge plate 2 is fixed on one side of the inclined pressure frame, and the fixed plate is fixed on the outer surface of the square plate, and two sliding bars 3 are fixed on the outer surface of the fixed plate, and the two sliding bars 3 are both slidably connected with the inclined pressure frame, and the outer surfaces of the two sliding bars 3 are both sleeved with telescopic springs 3, and the two telescopic springs 3 are fixedly connected between the inclined pressure frame and the fixed plate. After stamping, the movable frame drives the stamping die to move away from the pressure die. At this time, since the wedge plate 1 is limited by the wedge plate 2, five jacking tubes will extend out of the stamping die, and the five jacking tubes will limit the stamping waste in the pressure die, so that the stamping waste is separated from the stamping die, and prevent the stamping waste from being brought out by the stamping die.

[0015] Compared with the prior art, the stamping die of the wiring harness power terminal stamping equipment has the following beneficial effects:

[0016] 1. The present invention is provided with a stamping mechanism and a limiting assembly. After the stamping die cooperates with the pressure die to stamp the raw material, the five ejector tubes in the stamping die are limited and remain in the pressure die, and the stamping die will be away from the pressure die, so that the waste after stamping is separated from the stamping die, and at the same time, the air flow impacts the waste in the pressure die through the air outlet holes on the end face of the ejector tube, so that the waste can be discharged to the outside through the discharge pipe, which is convenient for the staff to collect the waste uniformly, and at the same time avoids the problem of waste jumping up and affecting subsequent stamping operations.

[0017] 2. The present invention is provided with a rotation mechanism and a stamping mechanism. After the stamping die close to the pressure die has been stamping for a long time, the rotating tube is controlled to rotate 180 degrees to rotate the two stamping dies. After the rotation, the stamping die close to the pressure die continues to perform the stamping operation, while the stamping die away from the pressure die will be cleaned by the high-pressure gas blown out by the high-pressure air gun to blow off the metal debris remaining on the surface of the stamping die. Therefore, the device can still perform stamping operations during the process of cleaning and maintaining the stamping die, and can perform continuous stamping operations.

[0018] Other advantages, objectives and features of the present invention will be set forth in part in the following description and, in part, will be apparent to those skilled in the art based on an examination of the following or may be taught from the practice of the present invention.

[0042] See also Figure 3 and Figure 4 The material unwinding and rewinding assembly 4 also includes a support frame 401 fixed on the left side of the base 1, and a raw material unwinding machine 402 and a finished product unwinding machine 403 are installed above the support frame 401. The raw material unwinding machine 402 is located on the left side of the limit block 404, and the finished product unwinding machine 403 is located above the limit block 404. Baffle plates 407 are fixed on both sides of the limit block 404, and two material discharge pipes 408 are fixedly connected to the outer surface of the limit block 404.

[0043] Before the stamping operation, the raw material metal strip is installed at the output end of the raw material unwinder 402, and then one end of the metal strip passes through the bottom of the limit block 404 and fits on the outer surface of the limit block 404, and then one end of the metal strip is installed on the finished product unwinder 403. During stamping, the metal strip is moved by controlling the raw material unwinder 402 and the finished product unwinder 403, and the stamping die 301 cooperates with the pressure die 406 to continuously stamp the metal strip. Two baffle plates 407 are provided to limit the metal to prevent the metal strip from shifting during movement. The waste generated during stamping will fall below through the discharge pipe 408, which is convenient for the staff to collect the waste.

[0044] Please refer to Figure 5 , Figure 6 , Figure 7 and Figure 8 The rotation mechanism 2 also includes a vent pipe 203, which is fixed to the inner wall of the rotating tube 201. A rotary air pipe joint 204 is installed at one end of the vent pipe 203. The rotary air pipe joint 204 is fixed to the outer surface of the base 1. The stamping mechanism 3 also includes a spring air pipe 313 fixedly connected to the vent pipe 203. One end of the spring air pipe 313 away from the vent pipe 203 is fixedly connected to a diverter box 312. The outer surface of the diverter box 312 is fixedly connected to five jacking tubes 311. The five jacking tubes 311 all penetrate the stamping die 301 and are slidably connected to the stamping die 301. The outer surface and end face of each jacking tube 311 are provided with air outlet holes. The external gas is pressurized and flows into the vent pipe 203 through the rotary air pipe joint 204. The gas in the vent pipe 203 will flow into the jacking tube 311 through the spring air pipe 313 and the diverter box 312. When the jacking tube 311 extends from the stamping die 301 and is located at the pressure die 406, the air outlet holes on the outer surface of the jacking tube 311 will spray air to clean the metal debris remaining in the pressure die 406. At the same time, the air outlet holes on the end face of the jacking tube 311 will spray air to blow the stamping waste remaining in the pressure die 406, so that the stamping waste falls to the outside through the discharge pipe 408.

[0045] The stamping mechanism 3 also includes four limit rods 303 fixed on the square plate 202. A movable frame 302 is fixed on one side of the stamping die 301 close to the square plate 202. The four limit rods 303 are slidably connected to the movable frame 302. Semi-annular rails 317 are fixed on both sides of the movable frame 302. When the semi-annular rail 317 on the left side of the rotating tube 201 and the semi-annular rail 317 on the right side of the rotating tube 201 are closed, a full-annular rail is formed, and the axis center line of the full-annular rail coincides with the axis center line of the rotating tube 201.

[0046] The rotation mechanism 2 also includes a press 208 fixed on the right side of the base 1, a U-shaped plate 209 is fixed to the telescopic end of the press 208, the U-shaped plate 209 is slidably connected to the inner bottom wall of the base 1, two connection frames 210 are fixed above the U-shaped plate 209, and the inner walls of the two connection frames 210 are fixed with toggle sliders 211, and the two toggle sliders 211 are respectively slidably connected to the two semi-circular rails 317 near the side of the limit block 404. When stamping, the press 208 is controlled to drive the two toggle sliders 211 on the U-shaped plate 209 to move, and the two toggle sliders 211 will respectively toggle the two semi-circular rails 317 near the side of the pressure die 406, so that the movable frame 302 drives the stamping die 301 to approach the pressure die 406, and the stamping die 301 cooperates with the pressure die 406 to stamp the raw material. When the U-shaped plate 209 is controlled to drive the toggle slider 211 to move so that the semi-circular rails 317 on the left and right sides of the rotating tube 201 are closed into full-circular rails, the full-circular rails can slide with the toggle slider 211 .

[0047] Please refer to Figure 6 , Figure 7 and Fig. 9 A gear 205 is fixed to the outer surface of the rotating tube 201, a motor 206 is fixed to the outer surface of the base 1, a gear 207 is fixed to the output end of the motor 206, the gear 207 is meshed with the gear 205, a support frame 212 is fixed to the right side of the base 1, a high-pressure air gun 213 is installed on the outer surface of the support frame 212, and two limit sliders 214 are fixed on the top of the base 1, and the two limit sliders 214 are respectively slidably connected to the two semi-annular rails 317 on the side away from the limit block 404.

[0048] When the two stamping dies 301 need to be rotated, the semi-circular tracks 317 on the left and right sides of the rotating tube 201 are first closed, and the motor 206 is controlled to drive the gear 2 207 to rotate. The gear 2 207 rotates through the gear 1 205 to drive the rotating tube 201 to rotate 180 degrees, so that the stamping dies 301 on the left and right sides of the square plate 202 are rotated, and the stamping die 301 on the left side of the square plate 202 (the side close to the pressure die 406) performs the stamping operation, while the stamping die 301 on the right side of the square plate 202 is cleaned by the high-pressure gas blown out by the high-pressure air gun 213 to blow off the metal debris attached to the surface of the stamping die 301. By setting a limiting slider 214, when the two stamping dies 301 are rotated, the limiting slider 214 will limit the semi-circular track 317 on the right side of the rotating tube 201 to prevent the stamping die 301 on the right side of the rotating tube 201 from sliding out.

[0049] Please refer to Fig. 9 and Fig.10The stamping mechanism 3 also includes an extrusion frame 304, which is slidably connected to the outer surface of the stamping die 301. Four slide bars 305 are fixed to the outer surface of the extrusion frame 304. Four fixed blocks 306 are fixed to the outer surface of the stamping die 301. The four fixed blocks 306 are slidably connected to the four slide bars 305 respectively. The outer surfaces of the four slide bars 305 are sleeved with telescopic springs 307. One end of the four telescopic springs 307 is fixed to the extrusion frame 304, and the other end of the four telescopic springs 307 is fixed to the four fixed blocks 306 respectively. When the stamping die 301 is close to the pressure die 406 for stamping, the extrusion frame 304 will first press the raw material to prevent the raw material from sliding sideways during the stamping process. After the stamping die 301 is removed from the pressure die 406, the extrusion frame 304 is reset by the spring pressure of the four telescopic springs 307.

[0050] Please refer to Fig.11 and Fig.13 , a moving plate 310 is fixed on the outer surface of the shunt box 312, two slide bars 308 are fixed on the side of the stamping die 301 close to the moving plate 310, the two slide bars 308 are slidably connected to the moving plate 310, the two slide bars 308 are fixed with a stopper 316 at one end away from the stamping die 301, the outer surfaces of the two slide bars 308 are sleeved with telescopic springs 309, the two telescopic springs 309 are fixedly connected between the moving plate 310 and the stamping die 301, and a wedge plate 314 is fixed on the bottom surface of the moving plate 310. When the movable frame 302 drives the stamping die 301 to approach the pressure die 406, the stamping die 301 moves and pushes the moving plate 310 to move through the stopper 316, so that the five push tubes 311 move with the stamping die 301.

[0051] Please refer to Fig.11 and Fig.12 A squeezing roller 315 is fixed to the inner wall of the movable frame 302, and a limiting assembly 5 is arranged below the squeezing roller 315. The limiting assembly 5 includes an inclined pressure frame 501 and a fixed plate 503. The inclined pressure frame 501 corresponds to the position of the squeezing roller 315. A wedge plate 2 502 is fixed to one side of the inclined pressure frame 501. The fixed plate 503 is fixed to the outer surface of the square plate 202. Two sliding rods 3 504 are fixed to the outer surface of the fixed plate 503. The two sliding rods 3 504 are both slidably connected to the inclined pressure frame 501. The outer surfaces of the two sliding rods 3 504 are both sleeved with telescopic springs 3 505. The two telescopic springs 3 505 are fixedly connected between the inclined pressure frame 501 and the fixed plate 503.

[0052] Please refer to Fig.11When stamping starts, the movable frame 302 drives the stamping die 301 to move close to the pressure die 406, and the squeezing roller 315 in the movable frame 302 no longer squeezes the inclined pressure frame 501. The inclined pressure frame 501 moves upward under the spring pressure of the two telescopic springs 3 505, and the inclined pressure frame 501 drives the wedge plate 2 502 to move to a height compatible with the wedge plate 1 314.

[0053] Please refer to Fig.14 During stamping, the movable frame 302 drives the stamping die 301 to extend into the pressure die 406. At this time, the wedge plate 1 314 squeezes the wedge plate 2 502 and passes over the wedge plate 2 502. Then the wedge plate 2 502 will limit the wedge plate 1 314.

[0054] Please refer to Fig.15 After stamping, the movable frame 302 drives the stamping die 301 to move away from the pressure die 406. At this time, since the wedge plate 1 314 is limited by the wedge plate 2 502, the five push tubes 311 will extend from the stamping die 301. The five push tubes 311 will limit the stamping waste in the pressure die 406, separate the stamping waste from the stamping die 301, and prevent the stamping waste from being brought out by the stamping die 301.

[0055] After the movable frame 302 drives the stamping die 301 to continue to move away from the pressure die 406, the extrusion roller 315 in the movable frame 302 will extrude the inclined pressure frame 501, so that the inclined pressure frame 501 drives the wedge plate 2 502 to move downward, canceling the limit of the wedge plate 1 314 by the wedge plate 2 502, and the movable plate 310 is driven by the spring tension of the telescopic spring 2 309 to reset the five push tubes 311, so that the five push tubes 311 are retracted into the stamping die 301.

[0056] Working principle: When stamping the raw material, the press machine 208 is controlled to drive the two toggle sliders 211 on the U-shaped plate 209 to move. The two toggle sliders 211 will respectively toggle the two semi-annular rails 317 close to the side of the pressure die 406, so that the movable frame 302 drives the stamping die 301 close to the pressure die 406, and the stamping die 301 cooperates with the pressure die 406 to stamp the raw material. After stamping, the movable frame 302 is controlled to drive the stamping die 301 away from the pressure die 406. At this time, since the wedge plate 1 314 is limited by the wedge plate 2 502, the five push tubes 311 will extend from the stamping die 301, and the five push tubes 311 will limit the stamping waste in the pressure die 406, so that the stamping waste is separated from the stamping die 301, and at the same time, the external air The body passes through the rotary air pipe joint 204, the vent pipe 203, the spring air pipe 313 and the diverter box 312 in sequence, and finally the air flow is ejected through the air outlet on the end face of the push tube 311, and the air flow will impact the waste in the pressure die 406, so that the waste can be discharged to the outside through the discharge pipe 408. After the movable frame 302 drives the stamping die 301 to continue to move away from the pressure die 406, the squeezing roller 315 in the movable frame 302 will squeeze the inclined pressure frame 501, so that the inclined pressure frame 501 drives the wedge plate 2 502 to move downward, canceling the limit of the wedge plate 2 502 on the wedge plate 1 314, and the movable plate 310 is driven by the spring tension of the telescopic spring 2 309 to reset the five push tubes 311, so that the five push tubes 311 are retracted into the stamping die 301, and the stamping operation is completed.

[0057] After the stamping die 301 near the pressure die 406 has been stamped for a long time, the press machine 208 is controlled to drive the two toggle sliders 211 to move, so that the two toggle sliders 211 will respectively toggle the two semi-annular tracks 317 near the pressure die 406, so that the semi-annular track 317 on the left side of the rotating tube 201 and the semi-annular track 317 on the right side of the rotating tube 201 are closed into a full annular track, and then the motor 206 is controlled to drive the gear 2 207 to rotate, so that the gear 2 207 drives the rotating tube 201 to rotate 180 degrees through the gear 1 205, so that the two stamping dies 301 are rotated. After the rotation, the stamping die 301 near the pressure die 406 continues to perform the stamping operation, while the stamping die 301 away from the pressure die 406 will be cleaned by the high-pressure gas blown out by the high-pressure air gun 213, and the metal debris remaining on the surface of the stamping die 301 will be blown off.

[0058] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
