Description

Technical Field

[0001] The utility model relates to the technical field of metal sheet processing equipment, in particular to a metal sheet conveying device and an automatic sheet cutting machine. Background Art

[0002] Metal sheets, also known as metal plates, are flat products made from metal raw materials through rolling, stretching or other forming processes. Metal sheets have multiple uses and a wide range of applications. For example, stainless steel sheets are often used in the production of tableware. The difference between metal sheets and metal coils is the thickness. The thickness of metal coils is about 1.5 cm, while the thickness of metal sheets is between 3 and 18 cm. Therefore, metal coils can be packaged in rolls, while metal sheets are packaged in sheet stacks.

[0003] The cutting of metal sheets refers to the process of cutting metal sheets into preset sizes and shapes by punching machines. However, due to the large thickness of metal sheets and their stacking, they cannot be automatically connected to the punching machine by unwinding after being rolled like metal coils. Therefore, the current cutting process of metal sheets still relies on manual operation.

[0004] With respect to the above-mentioned related technologies, the inventors believe that there are the following defects. First, during the manual loading process, due to the weight and volume of the metal sheet, it is difficult for the operator to accurately position it, and it is impossible to ensure that the metal sheet is accurately placed on the punch press mold each time the material is loaded, resulting in poor consistency in the cutting of the metal sheet and reduced accuracy in cutting and cutting of the metal sheet, which has a negative impact on the quality of the final product; secondly, the efficiency of manual loading and unloading is low, and it is difficult to match the high processing speed of the punch press, resulting in a low degree of automation in the cutting of the metal sheet, reducing the overall production efficiency and output; in addition, due to the heavy weight of the metal sheet, the labor intensity of the operator is increased. At the same time, the edges of the metal sheet are sharp, which can easily scratch the operator, increasing the risk of operation. Utility Model Content

[0036] Example 1: Figure 1-8As shown, a metal sheet 7 conveying device includes a frame 1, a material frame 2 for placing the metal sheet 7, a feeding mechanism 3 assembled on the frame 1 and used to move the metal sheet 7, and a picking mechanism 4 assembled on the frame 1 and used to transport the metal sheet 7 from the material frame 2 to the feeding mechanism 3. The picking mechanism 4 includes a bracket 401, an arm 402 and a suction cup 403. The bracket 401 is connected to the frame 1, and the arm 402 is movably assembled with the frame 1. The suction cup 403 is connected to the arm 402 and is used to absorb the surface of the metal sheet 7. Through the cooperation of the feeding mechanism 3 and the picking mechanism 4, the automatic conveying and positioning of the metal sheet 7 is realized, and the automation degree of the production line is improved. The operation reduces manual intervention, so that the cutting speed of the metal sheet 7 can match the high processing speed of the punch 6, thereby improving the overall production efficiency and output. Secondly, the suction cup 403 is used to adsorb the surface of the metal sheet 7 to ensure that the metal sheet 7 can be accurately placed on the punch 6 mold each time it is loaded, thereby improving the consistency and cutting accuracy of the metal sheet 7, and improving the accuracy and consistency of the metal sheet 7 cutting, so that the quality of the final product is improved. Furthermore, the conveying device replaces the manual handling of the operator, which reduces the labor intensity, reduces the labor cost, and reduces the safety hazard: it avoids the operator from directly contacting the sharp edge of the metal sheet, and reduces the risk of scratches and injuries.

[0037] In terms of the specific structure of the movable assembly of the support arm 402 and the frame 1, the material taking mechanism 4 is located above the feeding mechanism 3, and the material taking mechanism 4 also includes a transverse frame 404, which is assembled with the support 401 in a transverse sliding manner, and the support arm 402 is assembled with the transverse frame 404 in a vertical sliding manner. Through the transverse sliding assembly of the transverse frame 404 and the support 401, and the vertical sliding assembly of the support arm 402 and the transverse frame 404, the material taking mechanism 4 can move flexibly in a three-dimensional space, so that the material taking mechanism 4 can quickly and accurately complete the process of taking and placing materials, thereby greatly improving production efficiency. At the same time, due to the reduction of manual intervention, the error rate in the production process is also reduced, and the product quality is further improved.

[0038] It is worth mentioning that in order to facilitate the stacking of metal sheets 7, the horizontal height of the material rack 2 is lower than the horizontal height of the feeding mechanism 3, and the material rack 2 and the feeding mechanism 3 are in the same horizontal direction, preferably, close to the bottom surface of the conveying device, so that the metal sheets 7 can be easily placed on the material rack 2 after cutting, and the number of stacking is increased, reducing the risk of interference between the metal sheets 7 on the material rack 2 and the bracket 401, and increasing the operating space for placing the metal sheets 7 on the material rack 2.

[0039] In terms of the specific structure of the transverse sliding assembly of the transverse frame 404 and the bracket 401, the transverse frame 404 and the bracket 401 are slidably assembled through a gear rack, and the material picking mechanism 4 also includes a transverse rack 405, a transverse gear and a transverse motor 407. The transverse rack 405 is transversely assembled with the bracket 401, and the transverse gear is rotationally assembled with the transverse frame 404. The fixed end of the transverse motor 407 is connected to the transverse frame 404, and the rotating end of the transverse motor 407 is connected to the transverse gear shaft and is used to rotate the transverse gear. The transverse gear is tooth-meshingly assembled with the transverse rack 405. When the transverse gear rotates, it pushes the transverse frame 404 to move along the direction of the transverse gear. Preferably, a slide rail slider is installed between the transverse frame 404 and the bracket 401, the slide rail is connected to one end of the bracket 401 toward the transverse frame 404, and the slide rail is assembled on the bracket 401 along the sliding direction of the slide frame, one end of the slide rail is connected to the bottom wall of the slide frame, and the other end of the slide rail is slidably assembled with the slide rail, and the teeth of the transverse rack 405 are straight teeth. Through the precise tooth meshing assembly of the transverse gear and the transverse rack 405, the movement of the transverse frame 404 on the bracket 401 can achieve high-precision positioning, ensuring that the material picking mechanism 4 can accurately reach the specified position when moving horizontally, thereby improving the accuracy of picking and discharging the metal sheet 7.

[0040] In terms of the specific structure of the vertical sliding assembly of the support arm 402 and the transverse frame 404, the support arm 402 and the transverse frame 404 are slidably assembled through gear racks, and the material picking mechanism 4 also includes a vertical rack 408, a vertical gear, a vertical motor 411 and a U-shaped frame 410. The U-shaped frame 410 is assembled with the sliding frame and is used to support the support arm 402. The support arm 402 slides in the U-shaped frame 410. The vertical rack 408 is vertically assembled on the side wall of the support arm 402 facing the sliding frame. The fixed end of the vertical motor 411 is connected to the sliding frame, and the rotating end of the vertical motor 411 is connected to the vertical gear shaft and is used to rotate the vertical gear. The vertical gear is meshed with the vertical rack 408 for transmission, and is used to realize the vertical sliding assembly of the support arm 402 and the transverse frame 404. The teeth of the vertical rack 408 are helical teeth. The helical tooth design of the helical rack makes the transmission process smoother, reduces impact and vibration, thereby reducing noise, improving the overall operation quality of the equipment, and helping to disperse the load and reduce wear, thereby improving the transmission efficiency. Since the support arm 402 needs to bear the gravity of the metal sheet 7 when moving vertically, the helical rack can withstand a larger load than a straight rack, and has a certain reverse transmission capability. This means that even in the absence of a spring or special device, the helical rack can resist the reverse force to a certain extent, thereby ensuring the stability and safety of the conveying device.

[0041] Preferably, a slide rail slider is installed between the support arm 402 and the U-shaped frame 410, the slide rail is connected to the side wall of the support arm 402 and along the direction of the vertical rack 408, one end of the slider is connected to the inner wall of the U-shaped frame 410, and the other end of the slide rail is slidably assembled with the slide rail. In order to further improve the stability and smoothness of the sliding of the support arm 402, two groups of slide rail sliders are installed between the support arm 402 and the U-shaped frame 410, and the two groups of slide rail sliders are arranged opposite to each other. The two groups of slide rail sliders arranged opposite to each other further enhance the stability, make the movement of the support arm 402 more precise and reliable, and the two groups of slide rail sliders arranged opposite to each other share the load of the support arm 402 during vertical movement, thereby enhancing the bearing capacity of the entire structure.

[0042] In order to improve the stability of the picking mechanism 4 in adsorbing the metal sheet 7 and reduce the direction of the metal sheet 7 falling during the transportation process, a longitudinal portion 4021 is provided along the longitudinal extension of the support arm 402 at one end, and a plurality of groups of suction cups 403 are provided, and the plurality of groups of suction cups 403 are arranged at intervals along the longitudinal portion 4021. It should be noted that the suction cup 403 is an electric suction cup 403 in the prior art. The electric suction cup 403 is an electrically driven vacuum device, which generates negative pressure through a vacuum pump to adsorb and transport the metal sheet 7. Through the plurality of groups of suction cups 403, the suction force of the picking mechanism 4 for adsorbing the metal sheet 7 is improved, the adsorption stability of the picking mechanism 4 on the metal sheet 7 is enhanced, the risk of the metal sheet 7 falling during the transportation process is effectively reduced, and the safety of the entire transportation process is improved.

[0043] It is worth mentioning that after the support arm 402 is provided with the longitudinal portion 4021, the support arm 402 is arranged in an inverted "T" shape, and the longitudinal portion 4021 is parallel to the direction in which the feeding mechanism 3 moves the metal sheet 7. A plurality of groups of suction cups 403 are equidistantly connected to the longitudinal portion 4021 with the support arm 402 as the center, ensuring that the adsorption force of the suction cups 403 on the metal sheet 7 is more evenly distributed, which helps to better fix and carry the metal sheet 7 and reduce the risk of deviation or falling due to uneven adsorption.

[0044] In terms of the specific structure of the feeding mechanism 3, the feeding mechanism 3 includes a support member 301 and a pushing assembly 302. The support member 301 is provided with two groups along the longitudinal direction and is used to support the metal sheet 7. The two groups of support members 301 are arranged opposite to each other. The pushing assembly 302 is assembled with the frame 1 for longitudinal sliding and is located between the two groups of support members 301. The pushing assembly 302 is used to push the metal sheet 7 to move longitudinally. After the support arm 402 moves horizontally to the top of the material rack 2, the support arm 402 moves vertically downward to the suction cup 403 to abut against the metal sheet 7 and absorb the metal sheet 7. Then, the support arm 402 moves vertically upward and then moves horizontally to the top of the feeding mechanism 3. Then, the support arm 402 moves vertically upward and then moves horizontally to the top of the feeding mechanism 3. 2 moves downward until the metal sheet 7 is placed on the top wall of the support 301, then the suction cup 403 releases the metal sheet 7, and the pushing component 302 pushes the metal sheet 7 on the support 301 to move longitudinally. It should be noted that the material rack 2 is arranged in parallel with the support 301, and the two groups of oppositely arranged support members 301 provide a stable supporting surface for the metal sheet 7, and the pushing component 302 is located between the two groups of support members 301, which can accurately push the metal sheet 7 to move longitudinally on the support 301, thereby ensuring the stability and accuracy of the feeding process, enhancing the degree of automation of the equipment, reducing the need for manual intervention, and reducing labor costs.

[0045] In order to reduce the friction component between the metal sheet 7 and the support member 301 and improve the smoothness of sliding of the metal sheet 7, the feeding mechanism 3 also includes a support roller 303, which is rotatably assembled with the inner wall of the support member 301, and at least part of the support roller 303 is exposed on the top wall of the support member 301, and the rolling direction is parallel to the direction in which the pushing component 302 pushes the metal sheet 7 to move longitudinally. There are several groups of support rollers 303. When multiple groups are provided, the support rollers 303 are arranged at equal intervals along the support. It is worth mentioning that the side wall of one group of support members 301 facing the other group of support members 301 is defined as the inner wall of the support member 301, the side wall opposite to the inner wall of the support member 301 is defined as the outer wall of the support member 301, and the vertically upward end of the support member 301 is defined as the top wall of the support member 301. By arranging the support rollers 303 on the inner wall of the support member 301 and directly contacting the metal sheet 7, the friction between the metal sheet 7 and the support member 301 is reduced, so that the metal sheet 7 can slide more smoothly under the action of the pushing component 302, thereby reducing the resistance and improving the feeding efficiency.

[0046] When the pushing component 302 pushes the metal sheet 7 to move longitudinally along the support member 301, since the thrust acting on the metal sheet 7 is at one end of the metal sheet 7, the metal sheet 7 is prone to deviation during the longitudinal movement. In order to solve the problem of deviation of the metal sheet 7 when the pushing component 302 pushes the metal sheet 7 to move longitudinally, the feeding mechanism 3 includes a limiter 304, which is connected to the outer wall of the support member 301 and is used to limit the lateral movement of the metal sheet 7. Through the design of the limiter 304, the metal sheet 7 is transported longitudinally in a straight line according to the predetermined trajectory of the limiters 304 on the two groups of support members 301 during the longitudinal movement. It should be noted that the top wall of the limiter 304 is exposed to the top wall of the support roller 303, and the side wall of the limiter 304 is used to limit the lateral movement of the metal sheet 7, thereby effectively limiting the lateral movement of the metal sheet 7. This enables the metal sheet 7 to be conveyed in a straight line along the predetermined trajectory of the limit members 304 on the two groups of support members 301 when moving longitudinally, thereby ensuring the accuracy and stability of the feeding and reducing the deviation and error during the movement.

[0047] After the stopper 304 is provided, when the material taking mechanism 4 transfers the metal sheet 7 on the material rack 2 to the material feeding mechanism 3, it is easy to interfere with the stopper 304, thereby affecting the smoothness of the metal sheet 7 transfer. In order to solve the problem of interference between the metal sheet 7 and the stopper 304 when the metal sheet 7 is placed on the material feeding mechanism 3, the stopper 304 is assembled with the frame 1 in a horizontal sliding manner. The stopper 304 includes a stopper roller 3041 and a stopper block 3042. The stopper roller 3041 is assembled on the frame 1. The support arm 402 is arranged on the frame 1 and corresponds to one group of support members 301, the limit block 3042 is assembled on the frame 1 and corresponds to another group of support members 301, the rotation axis of the limit roller 3041 is arranged parallel to the Z axis, and the upper end of the limit block 3042 is provided with a guide slope 3043. After the support arm 402 moves horizontally to the top of the material rack 2, the support arm 402 moves vertically downward to the suction cup 403 to abut against the metal sheet 7 and absorb the metal sheet 7, then the support arm 402 moves vertically upward and then moves horizontally to the feeding mechanism 3. At the top, the two groups of limit members 304 move away from each other and move laterally, then the support arm 402 moves downward until the metal sheet 7 is placed on the top wall of the support 301, then the suction cup 403 releases the metal sheet 7, the two groups of limit members 304 approach each other and move laterally, so that the limit members 304 are located on the side walls of the metal sheet 7, thereby playing a role in lateral limiting the metal sheet 7, so that the metal sheet 7 can be smoothly placed on the top wall of the support 301, thereby improving the efficiency and stability of transportation, and the guide slope 3043 enables the metal sheet 7 to slide more smoothly into the predetermined position when placed on the support 301, and the guide slope 3043 plays a role in guiding and positioning, reducing the difficulty and error of placing the metal sheet 7, secondly, since the limit member 304 is assembled with the frame 1 in a transverse sliding manner, the position of the limit member 304 is adjusted according to the metal sheets 7 of different sizes, so that the feeding mechanism 3 can adapt to metal sheets 7 of different specifications and sizes, thereby improving the flexibility and versatility of the equipment.

[0048] In order to accommodate metal sheets 7 of different widths, the material taking mechanism 4 also includes a transverse adjustment screw 305, one end of which is connected to the limit block 3042, and the transverse screw is threadedly connected to the frame 1. The limit block 3042 can be adjusted transversely by adjusting the thread, thereby adapting to metal sheets 7 of different widths and improving production flexibility.

[0049] In order to facilitate the adjustment of the horizontal adjustment screw 305, the material picking mechanism 4 also includes a ruler, a pointer, and a handwheel 306. The handwheel 306 is axially connected to the other end of the horizontal adjustment screw 305. The ruler is connected to the frame 1 parallel to the X-axis. The pointer is connected to the limit and is located directly above the ruler. The lateral movement of the limit member 304 is quantified, so that the staff can intuitively see the adjustment range, thereby more accurately adjusting the position of the limit block 3042 and improving the adjustment accuracy.

[0050] In order to further adapt to metal sheets 7 of different widths, the support roller 303 can always be supported at a position close to the two side walls of the metal sheet 7, and the support member 301 is connected to the limit member 304, so that when the limit member 304 moves laterally, it drives the support member 301 to move laterally together.

[0051] In terms of the specific structure of the horizontal sliding assembly of the limiting roller 3041 and the frame 1, the feeding mechanism 3 also includes a connecting block 307, a sliding block 308, and a transverse cylinder 309. The limiting roller 3041 and the sliding block 308 are rotatably assembled, the fixed end of the transverse cylinder 309 is connected to the sliding block 308, the pushing end of the transverse cylinder 309 is connected to one end of the connecting block 307, one end of the connecting block 307 is connected to the outer wall of the support member 301, and a slide rail slider is installed between the sliding block 308 and the connecting block 307.

[0052] In terms of the specific structure of the pushing component 302, the pushing component 302 includes a lower clamping plate 3022, an upper clamping plate 3021, and a pushing cylinder 3023. The lower clamping plate 3022 is assembled with the machine base through a longitudinal sliding movement of a screw nut. The upper clamping plate 3021 moves back and forth toward the lower clamping plate 3022 to loosen and clamp the metal sheet 7. The lower clamping plate 3022 is protruding upward and is provided with a connecting frame. The upper clamping plate 3021 is rotatably connected to the connecting frame to form a fulcrum of the upper clamping plate 3021. One end of the upper clamping plate 3021 is used to clamp the metal sheet 7 between the lower clamping plate 3022. The other end of the upper clamping plate 3021 is connected to the fixed end of the pushing cylinder 3023. The push rod 3025 of the pushing cylinder 3023 is connected to the lower clamping plate 3022 to realize the back and forth movement of the upper clamping plate 3021 toward the lower clamping plate 3022 to loosen and clamp the metal Sheet 7, the lower clamping plate 3022 is assembled with the machine base in a longitudinal sliding manner to form a first screw nut, the first screw nut includes a first screw and a first nut, the pushing assembly 302 includes a first screw motor 3024, the first screw is a ball screw, the first screw is arranged parallel to the X-axis and is rotatably assembled with the frame 1, the first nut and the first screw are threadedly transmitted, the upper clamping plate 3021 is assembled on the first nut, the first screw motor 3024 is connected to the frame 1 and is used to rotate the first screw, it is worth mentioning that the lower clamping jaw is in a "convex" shape, and the two sides of the lower clamping jaw are used to avoid the two groups of support members 301, which improves the stability of the transportation of the metal sheet 7, automatically controls the clamping, loosening and longitudinal movement of the metal sheet 7, improves the convenience and automation of operation, and at the same time, it also reduces the labor intensity of the operator and improves production efficiency.

[0053] When the pushing component 302 pushes the metal sheet 7 to move longitudinally, the upper clamp and the lower clamp will interfere with the mold of the punch 6, and the part of the metal sheet 7 clamped by the upper clamp and the lower clamp cannot be punched by the punch 6. In order to improve the utilization rate of the metal sheet 7, the pushing component 302 also includes a push rod 3025, and the push rod 3025 is longitudinally slidably assembled with the upper clamp 3021. The push rod 3025 is located between the upper clamp 3021 and the lower clamp 3022 for pushing the metal sheet 7. The pushing component 302 also includes a second screw rod, a second nut, and a second screw rod motor 3026. The second screw rod is a ball screw rod. The second screw rod is arranged parallel to the X-axis and is connected to the lower clamp 3022. Rotate and assemble, the first nut and the first screw are threadedly transmitted, the push rod 3025 is assembled on the second nut, the second screw motor 3026 is connected to the upper clamp and is used to rotate the second screw. Through the screw nut transmission, the amount of the metal sheet 7 pushed by the push rod 3025 toward the punch 6 mold can be accurately controlled. Through the design of the push rod 3025, in addition to the part of the metal sheet 7 clamped by the upper clamp and the lower clamp, the remaining part of the metal sheet 7 is pushed toward the punch 6 mold, so that the part of the sheet that may have been discarded due to clamping can be used for punching, thereby improving the utilization rate of the metal sheet 7, avoiding interference with the punch 6 mold, and ensuring the smooth progress of the punching process.

[0054] In order to adapt to different punch press 6 mold heights, it also includes an adjustment mechanism mounted on the body 101 for vertically moving the material taking mechanism 4. The frame 1 includes the body 101 and the table 102. The table 102 is mounted on the body 101. The feeding mechanism 3 is mounted on the table 102. The adjustment mechanism includes an adjustment motor 501, a synchronization rod 502, a guide rod 503, a worm wheel, and a worm. The worm is arranged parallel to the Z axis. One end of the worm is connected to the table 102, and the other end of the worm is slidably assembled with the body 101. The worm wheel and the worm are meshed for transmission. The adjustment motor 5 01 is connected to the body 101 and is used to rotate the worm gear, one end of the guide rod 503 is connected to the table 102, and the other end of the guide rod 503 is slidably assembled with the body 101 and is used to guide the up and down movement of the table 102. There are two groups of guide rods 503, and the two groups of guide rods 503 are arranged at the longitudinal ends of the table 102. The synchronization rod 502 is used to transmit the unbalanced torque when the two groups of guide rods 503 move vertically, so that the table 102 can rise or fall smoothly, adapt to punch 6 molds of different heights, and improve the adaptability and versatility of the conveying device.

[0055] Embodiment 2, as Figure 1-10As shown, an automatic sheet material cutting machine includes a punching machine 6 and a metal sheet material 7 conveying device in Example 1. The punching machine 6 includes a workbench 601, and the workbench 601 is equipped with a die 602. The end of the support member 301 away from the pushing component 302 abuts against the side wall of the die 602. The top surface of the support member 301 and the top surface of the die 602 are on the same horizontal line. Of course, when the support member 301 is equipped with a support roller 303, the rotation of the adjustment motor 501 is controlled by the adjustment mechanism to make the table 102 move downward, thereby ensuring that the top wall of the support roller 303 and the die 602 are aligned. The top surfaces of the die 602 are on the same horizontal line. By closely combining the metal sheet 7 conveying device with the worktable 601 of the punch press 6, an automated process from conveying to punching of the metal sheet 7 is realized, reducing manual operation links and improving overall work efficiency. Secondly, the top surface of the support member 301 is on the same horizontal line as the top surface of the die 602 or the top wall of the support roller 303 is on the same horizontal line as the top surface of the die 602, ensuring that the metal sheet 7 can be stably placed on the die 602 during the punching process, avoiding punching quality problems caused by improper position.

[0056] When the pushing assembly 302 pushes the metal sheet 7 on the support 301 toward the die 602, the die 603 of the punch press 6 moves toward the die 602, thereby punching the metal sheet 7 into a preset semi-finished product. However, when the processing of the metal sheet 7 is almost completed, the upper and lower jaws interfere with the die 603, and the metal sheet 7 is gradually pushed onto the die 602 for processing through the reciprocating movement of the push rod 3025. At this time, the upper and lower jaws clamp and release the metal sheet 7, and the metal sheet 7 loses the downward pressure, so that the push rod 3025 pushes the metal sheet 7 forward. There is a direction of deviation. Therefore, in order to provide downward pressure on the metal sheet 7 when the push rod 3025 pushes the metal sheet 7, the pushing assembly 302 also includes a pressing roller 3027, a vertical arm 3028, and a swing arm 3029. The vertical arm 3028 is connected to the outer wall of the support member 301, and the vertical arm 3028 is located at one end close to the die 602. One end of the swing arm 3029 is rotatably assembled with the vertical arm 3028, and the other end of the swing arm 3029 is rotatably assembled with the pressing roller 3027. The axis of the pressing roller 3027 is parallel to the axis of the support roller 303. The swing arm 302 The pressing roller 3027 is tilted under the gravity of the pressing roller 3027, and the pressing roller 3027 is located between one group of supporting rollers 303 and another group of supporting rollers 303. In order to facilitate the metal sheet 7 to enter the lower part of the pressing roller 3027, the inclined opening of the swing arm 3029 is arranged toward the side of the pushing component 302. Preferably, in order to increase the downward pressure of the pressing roller 3027, a counterweight is installed on the side of the swing arm 3029 where the pressing roller 3027 is installed. Through the cooperation between the metal sheet 7 conveying device and the punch 6, the metal sheet 7 is automatically clamped and conveyed to the punch 6 mold for cutting. Shearing, after the processing of the metal sheet 7 is completed, the conveying device automatically conveys the next metal sheet 7. The whole process is highly automated, which not only improves the punching quality and work efficiency, but also reduces the safety risks during the punching operation. The design of the downward pressure roller 3027 provides a stable downward force when the processing of the metal sheet 7 is almost completed, which helps to ensure the stability and reliability of the punching process, and ensures that the metal sheet 7 can smoothly and accurately enter the die 602 for punching under the push of the push rod 3025, thereby improving the accuracy and quality of the blanking of the metal sheet 7 and reducing the processing scrap rate.
