[0003] When using a traditional stamping device, the die is usually installed on the operating table of the stamping machine using bolts, and then the metal plate is placed on the die. By applying external force, the metal plate is plastically deformed under the action of the die to obtain the required shape and size. Therefore, when installing or removing the die, the bolts need to be tightened repeatedly, which has low operating efficiency and poor flexibility.

[0004] When placing or removing the identification metal plate, the operator usually reaches between the operating table and the hydraulic press to insert the metal plate into the groove on the mold. When removing the formed metal plate, it is inconvenient to take it out due to the limited operating space between the hydraulic press and the operating table, resulting in low operating efficiency.

[0036] Specifically, Figure 2 , Figure 4 , Figure 6 , Figure 7 and Figure 8As shown, the driving structure 3 includes a mounting plate 301 and a first rotating shaft 302 rotatably connected to the center position of the mounting plate 301, the mounting plate 301 is fixedly connected to the bottom surface of the bottom plate 202, a motor 309 is fixedly connected to the bottom surface of the mounting plate 301, an output shaft of the motor 309 is fixedly connected to the first rotating shaft 302, a driving rod 303 is fixedly connected to the first rotating shaft 302, both ends of the driving rod 303 are rotatably connected to a second rotating shaft 304, a connecting rod 305 is rotatably connected to the second rotating shaft 304, and two slide plates 307 are slidably connected to the inside of the bottom plate 202.

Since the motor 309 is installed on the bottom plate 202 through the mounting plate 301, it is easy to disassemble. At the same time, it is easy to disassemble the mounting plate 301 to repair the parts inside the bottom plate 202. It has strong flexibility. The first rotating shaft 302 drives the driving rod 303 to rotate. Since the two ends of the driving rod 303 are respectively connected to the connecting rod 305 through a second rotating shaft 304, the driving rod 303 drives the connecting rods 305 at both ends to rotate counterclockwise. Since the other end of the connecting rod 305 is always connected to the center position of the slide plate 307 through the driving column 306, during the counterclockwise rotation of the driving rod 303, the two The ends of the connecting rods 305 connected to the driving rod 303 move to both sides respectively, and the other ends of the two connecting rods 305 drive the driving column 306 to move toward the center position of the first rotating shaft 302. At this time, the driving column 306 drives the slide plate 307 to slide toward the center position along the guide rod 308, so as to facilitate the subsequent clamping and fixation of the lower mold 8. At the same time, when the mold needs to be replaced, it is only necessary to drive the motor 309 to drive the first rotating shaft 302 to rotate clockwise. At the same time, the distance that the clamp slides toward the center position can be controlled by controlling the rotation angle of the first rotating shaft 302, so as to facilitate the fixation of lower molds 8 of different sizes, which is highly practical.

[0037] Specifically, Figure 2 , Figure 6 , Figure 7 and Figure 8As shown, the fixed structure 4 includes a fixed plate 401 and a first connecting rod 402 slidably connected to the fixed plate 401, each of the two slide plates 307 is fixedly connected to a fixed plate 401, the fixed plate 401 is slidably connected to the bottom plate 202, the end of the first connecting rod 402 is fixedly connected to a first clamping plate 403, a spring 405 is fixedly connected between the back of the first clamping plate 403 and the fixed plate 401, a nut 404 is threadedly connected to the first connecting rod 402, the nut 404 and the outer wall of the fixed plate 401 are in conflict with each other, the fixed plate 401 and the first connecting rod 402 are both in a "U" shape, the two fixed plates 401 are symmetrically arranged, and the two fixed There is a lower mold 8 in contact between the plates 401; when the two slide plates 307 drive the two fixed plates 401 to clamp towards the middle, the first clamping plate 403 on the fixed plate 401 clamps the two sides of the lower mold 8, and the installation of the lower mold 8 is completed at this time, and the firmness is strong. If the size of the lower mold 8 is too small, the small-sized lower mold 8 is first placed between the two first clamping plates 403. The two first clamping plates 403 initially clamp the lower mold 8 under the reset action of the spring 405, and then the nut 404 on the first connecting rod 402 is rotated to move it to the two sides of the lower mold 8, so that the nut 404 and the outer wall of the fixed plate 401 are in contact with each other, and the small-sized lower mold 8 is fixed at this time, which is easy to operate and flexible.

[0038] Specifically, Figure 1-Figure 3 , Figure 5 , Figure 6 , Figure 8 and Fig. 9As shown, the adjustment structure 5 includes a slide groove 501 and an adjustment plate 502 slidably connected to the inside of the slide groove 501. The two guide frames 201 are both provided with a slide groove 501. The adjustment plate 502 is threadedly connected with a limit rod 503. The end of the limit rod 503 and the inner wall of the slide groove 501 conflict with each other. The adjustment plate 502 is fixedly connected with two mounting brackets 504 by screws 505. The adjustment plate 502 is a "U"-shaped structure, and the mounting bracket 504 is an "L"-shaped structure. The mounting bracket 504 is matched with a clamping structure 6. After the lower mold 8 is installed on the equipment, the upper mold 9 is installed. The limit rod 503 on the outer side of the adjustment plate 502 is first rotated so that the end of the limit rod 503 is no longer in contact with the slide groove. The inner wall of the groove 501 is in conflict, and then the adjustment plate 502 is slid along the slide groove 501 so that the center point of the adjustment plate 502 is on the same straight line with the center point of the lower mold 8, and then the limit rod 503 is rotated in the opposite direction to limit the position of the adjustment plate 502. At the same time, since the length of the adjustment plate 502 can be adjusted within a certain range, it is convenient to adjust the length of the adjustment plate 502 according to the size of the upper mold 9, so as to adapt to upper molds 9 of different sizes. At the same time, the position between the mounting frame 504 and the adjustment plate 502 can be adjusted according to the thickness of the lower mold 8, and fixed with screws 505, and ensure that the upper mold 9 is located directly above the lower mold 8, avoiding the need to repeatedly align the upper mold 9 and the lower mold 8 when placing the metal plate, thereby improving operating efficiency.

[0039] Specifically, Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 8 and Fig. 9As shown, the clamping structure 6 includes a mounting rod 601 and a tension spring 603 running through the mounting rod 601, each of the four mounting frames 504 is fixedly connected with a mounting rod 601, a support plate 602 is slidably connected between two symmetrical mounting rods 601, a tension spring 603 is fixedly connected between the top surface of the support plate 602 and the mounting frame 504, a second connecting rod 606 is slidably connected to one of the support plates 602, and the end of the second connecting rod 606 is fixedly connected with a second The clamping plate 605, the center position of the second clamping plate 605 is rotatably connected with a screw rod 604, the screw rod 604 is threadedly connected to the support plate 602, the other support plate 602 is fixedly connected with a rubber pad 607, the second clamping plate 605 is fixedly connected with another rubber pad 607, the two rubber pads 607 are in contact with the upper mold 9, the cross section of the mounting rod 601 is a "T"-shaped structure, and the end of the screw rod 604 is fixedly connected with a knob 608; when adjusting the two adjustment plates 502, the two support plates 602 are driven to move to the center position of the lower mold 8, and then one hand takes the upper mold 9, so that the bottom surface of the upper mold 9 is flush with the bottom surface of the support plate 602, and then the other hand turns the knob 608 at the end of the screw rod 604, and then the screw rod 604 drives the second clamping plate 605 and the second connecting rod 606 to move in the direction of the upper mold 9, until the rubber pad 607 on the other support plate 602 and the rubber pad 607 on the second clamping plate 605 are both in contact with the upper mold 9, at this time, the installation of the upper mold 9 is completed, and the firmness is strong. During the stamping process, the hydraulic press drives the stamping plate to move downward, and the bottom surface of the stamping plate first contacts the surface of the upper mold 9, and then drives the support plate 602 to stretch the tension spring 603, so that the support plate 602 slides downward along the mounting rod 601 until it contacts the metal plate on the lower mold 8, and then completes the processing of the metal plate, and then drives the upper mold 9 to move to the initial position under the reset force of the tension spring 603, which is convenient for processing the next metal plate and has strong flexibility.

[0040] When the present invention is used, the lower die 8 is mounted on the operating table of the punching machine body 1. First, the lower die 8 is placed at the center of the bottom plate 202. Then, the motor 309 on the bottom surface of the bottom plate 202 drives the first rotating shaft 302 to rotate counterclockwise. Since the motor 309 is mounted on the bottom plate 202 through the mounting plate 301, it is easy to disassemble. At the same time, it is easy to disassemble the mounting plate 301 to repair the parts inside the bottom plate 202. The first rotating shaft 302 drives the driving rod 303 to rotate. Since the two ends of the driving rod 303 are respectively A second rotating shaft 304 rotates to connect the connecting rod 305, and then the driving rod 303 drives the connecting rods 305 at both ends to rotate counterclockwise. Since the other end of the connecting rod 305 is always connected to the center position of the slide plate 307 through the driving column 306, during the counterclockwise rotation of the driving rod 303, the ends of the two connecting rods 305 connected to the driving rod 303 move to both sides respectively, and the other ends of the two connecting rods 305 drive the driving column 306 to move toward the center position of the first rotating shaft 302. At this time, the driving column 306 drives the slide plate 307 along The guide rod 308 slides toward the center position, so as to facilitate the subsequent clamping and fixing of the lower mold 8. At the same time, when the mold needs to be replaced, it is only necessary to drive the motor 309 to drive the first rotating shaft 302 to rotate clockwise. At the same time, the sliding distance of the clamp toward the center position can be controlled by controlling the rotation angle of the first rotating shaft 302, so as to facilitate the fixing of lower molds 8 of different sizes. It is highly practical. When the two slide plates 307 drive the two fixing plates 401 to clamp in the middle, the first clamping plate 403 on the fixing plate 401 clamps the two sides of the lower mold 8. The lower mold 8 is installed and fixed. If the size of the lower mold 8 is too small, the small-sized lower mold 8 is placed between the two first clamping plates 403. The two first clamping plates 403 initially clamp the lower mold 8 under the reset action of the spring 405. Then, the nut 404 on the first connecting rod 402 is rotated to move it to both sides of the lower mold 8, so that the nut 404 and the outer wall of the fixing plate 401 are in conflict with each other. At this time, the small-sized lower mold 8 is fixed. The operation is simple and the flexibility is strong.

[0041] After the lower mold 8 is installed on the equipment, the upper mold 9 is installed. First, the limiting rod 503 on the outer side of the adjustment plate 502 is rotated so that the end of the limiting rod 503 no longer conflicts with the inner wall of the slide groove 501, and then the adjustment plate 502 is slid along the slide groove 501 so that the center point of the adjustment plate 502 and the center point of the lower mold 8 are on the same straight line, and then the limiting rod 503 is rotated in the opposite direction to limit the position of the adjustment plate 502. At the same time, since the length of the adjustment plate 502 can be adjusted within a certain range, it is convenient to adjust the length of the adjustment plate 502 according to the size of the upper mold 9, so as to adapt to upper molds 9 of different sizes. At the same time, the position between the mounting frame 504 and the adjusting plate 502 can be adjusted according to the thickness of the lower mold 8, and the screw 505 is used to fix it, and it is ensured that the upper mold 9 is located directly above the lower mold 8, avoiding the need to repeatedly align the upper mold 9 and the lower mold 8 when placing the metal plate, thereby improving the operation efficiency.

[0042] When adjusting the two adjustment plates 502, the two support plates 602 are driven to move toward the center of the lower mold 8, and then one hand takes the upper mold 9 so that the bottom surface of the upper mold 9 is flush with the bottom surface of the support plate 602. Then the other hand turns the knob 608 at the end of the screw rod 604, and then the screw rod 604 drives the second clamping plate 605 and the second connecting rod 606 to move toward the upper mold 9 until the rubber pad 607 on the other support plate 602 and the rubber pad 607 on the second clamping plate 605 are aligned with the upper mold 9. The upper die 9 is in contact with the tool 9, and the installation of the upper die 9 is completed at this time, which is strong in firmness. During the stamping process, the hydraulic press drives the stamping plate to move downward, and the bottom surface of the stamping plate first contacts the surface of the upper die 9, thereby driving the support plate 602 to stretch the tension spring 603, so that the support plate 602 slides downward along the installation rod 601 until it contacts the metal plate on the lower die 8, thereby completing the processing of the metal plate, and then driving the upper die 9 to move to the initial position under the reset force of the tension spring 603, which is convenient for processing the next metal plate, and has strong flexibility;

[0043] When taking out the processed marking metal plate on the lower mold 8, the telescopic end of the hydraulic rod 203 on the punching machine body 1 extends outward, and drives the bottom plate 202 to slide outward along the inner wall of the guide frame 201 through the connecting plate 204 until it slides to the maximum distance. At this time, the upper mold 9 and the lower mold 8 are effectively misaligned, which is convenient for taking the metal plate, while increasing the operating space and improving the operating efficiency.
