There are two wedge blocks 242 and they are symmetrically distributed with the lower module 22 as the center.

[0043] An elastic member 254 is provided on the side of the pressure block 251 away from the tension spring 252. The pressure block 251 has an inclined surface and a groove 2511 is formed on the side of the pressure block 251 near the fixing plate 253. A connecting rod 255 is fixedly connected to the lower surface of the slider 12. Two groups of pressure blocks 251 are provided, symmetrically distributed front-to-back around the lower module 22. Multiple elastic members 254 are designed as curved strips and are arranged in an array along the longitudinal direction of the pressure block 251.

[0044] The slider 12 is internally rotatably connected to a screw rod 14 , the outer surface of the screw rod 14 is sleeved with a connecting rod, and the end of the connecting rod away from the slider 12 is rotatably connected to a crankshaft 15 , and the outer end of the crankshaft 15 is rotatably connected to the inside of the frame 11 .

[0045] The process of conveying the plate:

[0046] During actual use, the sheet material to be processed is fed to the upper surface of the lower roller 232. Both the upper roller 236 and the lower roller 232 are electrically driven. The lower roller 232 is provided with multiple groups and extends a long distance away from the frame 11. When the sheet material is placed on the upper surface of the lower roller 232, the lower roller 232 automatically rotates and moves the sheet material on its upper surface toward the lower module 22. Accordingly, the upper roller 236 and the lower roller 232 rotate in opposite directions. After the upper roller 236 contacts the sheet material, it will also move the sheet material toward the lower module 22.

[0047] In the initial state, the side of the bottom frame 231 is rotatably connected to the connecting rod 233 via a shaft. A strong torsion spring 234 is sleeved on the outer surface of the shaft and connected to the interior of the connecting rod 233. This strong torsion spring 234 maintains a small angle between the bottom frame 231 and the connecting rod 233, while remaining unaffected by external forces. This reduces the distance between the bottom frame 231 and the top frame 235, allowing thinner plates to pass through. Two sets of connecting rods 233 are provided, with two connecting rods 233 per set, as shown on one side.

[0048] The top frame 235 adopts a segmented design, the connecting rod 233 on the side away from the frame 11 is the rear connecting rod 233, and the side close to the frame 11 is the front connecting rod 233. The top frame 235 in the middle section between the front connecting rod 233 and the rear connecting rod 233 is set horizontally, and the top frame 235 of the horizontal section is in a horizontal state with the bottom frame 231. The rear connecting rod 233 on the top frame 235 to its end section adopts an arc design, and the side of the arc section away from the frame 11 is higher, and the overall curvature is gentle, which is conducive to the smooth entry of the plate into the space between the upper roller 236 and the lower roller 232.

[0049] When a thicker sheet of material is conveyed from lower roller 232 until it moves below upper roller 236, upper roller 236, located between the two curved sections of upper frame 235, also follows its curvature, assuming an overall curved position. The sheet's lower surface abuts the top of lower roller 232. As its upper surface approaches upper roller 236, the sheet's outer edge near upper die assembly 13 contacts the outer surface of one of the inclined upper rollers 236. As the sheet continues to move toward upper die assembly 13, the sheet's thickness exceeds the initial gap between the horizontal upper roller 236 and lower roller 232, causing the upper roller 236 and upper frame 235 to be lifted upward by the sheet. During this process, the distance between upper frame 235 and bottom frame 231 increases, widening the angle between connecting rod 233 and bottom frame 231. The strong torsion spring 234, connected to connecting rod 233, rotates around the shaft along with the connecting rod 233 and undergoes elastic deformation.

[0050] At this point, the front end of the sheet has entered the flat section of the top frame 235. The distance between the upper roller 236 and the lower roller 232 is equal to the thickness of the sheet. The upper surface of the sheet aligns with the bottom edge of the upper roller 236, and the lower surface of the sheet aligns with the top edge of the lower roller 232. The upper roller 236 and the lower roller 232 rotate in opposite directions. The outer surfaces of the upper roller 236 and the lower roller 232 have a large friction force. This friction force moves the sheet placed between the upper roller 236 and the lower roller 232 toward the upper die 13. The lower roller 232 is higher from the workbench 21 than the lower die 22, so that the sheet can be smoothly moved to the upper surface of the lower die 22 for stamping.

[0051] The process of adjusting the punching force according to the thickness of the sheet:

[0052] As the sheet material enters the loading member 23, the connecting rod 233 rotates clockwise around the shaft by a certain angle. At this time, the gear 246 fixedly connected to the outer surface of the connecting rod 233 rotates clockwise synchronously. The rotation of the gear 246 drives the transmission gear 245 meshing with it to rotate counterclockwise. The end of the transmission gear 245 away from the frame 11 is fixedly connected to a worm 244 rotatably connected via the shaft seat, which drives the worm 244 to rotate counterclockwise. The worm 244 rotates the double-threaded rod 241 inside the support seat through the worm gear 243. Because the threads on both sides of the outer surface of the double-threaded rod 241 are arranged in opposite directions, when the double-threaded rod 241 rotates, the two wedge blocks 242 meshing with each other through the threads move toward each other.

[0053] Because the oblique edge of the wedge block 242 fits against the side of the lower die 22, when the wedge block 242 moves toward the lower die 22, the wedge block 242 converts the horizontal force applied to the lower die 22 into a vertical force, causing the lower die 22 to move slightly upward under the positioning of the positioning pin 211 (in the initial state, the lower die 22 is connected to the upper surface of the workbench 21 via the positioning pin 211, ensuring the horizontal fixation of the lower die 22. The workbench 21 is magnetically connected to the lower die 22, and a certain suction force is maintained between the lower die 22 and the upper surface of the workbench 21). The initial gap between the upper roller 236 and the lower roller 232 increases by the thickness of the plate. At this time, when the distance between the lower die 22 and the upper die 13 decreases, the impact force will gradually increase as the distance decreases. This is because during this process, the mold closing speed is relatively stable. As the distance decreases, the distance that the upper mold assembly 13 works on the lower mold assembly 22 per unit time is shortened. According to the impulse theorem, when the momentum change remains unchanged, a smaller action distance means that the impact force will increase.

[0054] When the thickness of the plate is equal to the distance between the upper roller 236 and the lower roller 232 in the initial state, the plate will not cause the top frame 235 and the upper roller 236 to be lifted upward when the plate is loaded, and the angle of the connecting rod 233 will not change, that is, the adjustment part 24 will not change as a result. The lower mold assembly 22 is in the initial position. At this time, the distance between the lower mold assembly 22 and the upper mold assembly 13 is suitable for the plate of this thickness, that is, the punching force of the plate of this thickness is suitable in this case, and no additional adjustment is required.

[0055] The process of the horizontal positioning member 25 correcting the position of the plate:

[0056] When the plate enters between the upper die group 13 and the lower die group 22, and the plate fits with the upper surface of the lower die group 22, the stamping part 1 is started to start the stamping operation. The driving unit arranged on the outer surface of the frame 11 is connected to the crankshaft 15 for transmission. The connecting rod sleeved on the outer surface of the crankshaft 15 drives the screw 14 to rotate. The screw 14 is connected to the slider 12 through the die handle, driving the slider 12 to slide on the outer surface of the frame 11 as a whole. When the crankshaft 15 drives the connecting rod upward, the slider 12 is at the top dead point. At this time, the distance between the upper die group 13 and the lower die group 22 is the largest. When the crankshaft 15 rotates to drive the connecting rod downward, the slider 12 drives the upper die group 13 downward for stamping.

[0057] During the downward stamping process of the upper die assembly 13, a connecting rod 255 is fixedly connected to the lower surface of the slider 12. The connecting rod 255 is L-shaped, and its height is greater than the thickness of the upper die assembly 13. As the upper die assembly 13 moves downward, the bottom end of the connecting rod 255 contacts the oblique edge of the pressing block 251. Two pressing blocks 251 are arranged symmetrically about the lower die assembly 22. The top of each pressing block 251 is provided with an oblique surface, which is higher on the side closer to the lower die assembly 22. When the upper die assembly 13 moves downward, the bottom end of the connecting rod 255 contacts the oblique edge of the pressing block 251. Due to the oblique surface design of the pressing block 251, the vertical downward force applied by the connecting rod 255 is converted into a horizontal force, driving the pressing block 251 toward the lower die assembly 22.

[0058] As the connecting rod 255 moves downward, the distance the pressing block 251 moves toward the center also gradually increases. The pressing blocks 251 on both sides move toward the center synchronously until they press the two sides of the plate placed on the upper surface of the lower mold 22 to correct the position. The elastic members 254 provided on the outer surface of the pressing block 251 can fit with the side edges of the plate. The elastic members 254 can be designed in the form of curved strips, with multiple members arranged in an array in the longitudinal direction. When the pressing block 251 corrects the position of the plate above the lower mold 22, the curved strips above the height of the lower mold 22 do not contact the side edges of the lower mold 22. Their curved surfaces contact the side edges of the plate, squeezing the plate into position from both sides, which helps to eliminate gaps. The curved strips below the height of the lower mold 22 are tightly attached to the side edges of the lower mold 22 and undergo elastic deformation. When the height of the lower module 22 changes due to different plate thicknesses, the elastic member 254 on the outer surface of the pressing block 251 is a plurality of longitudinally arranged arc-shaped strips that can accommodate plates of different heights placed above the lower module 22 .

[0059] When the connecting rod 255 continues to move downward, the distance between the upper mold 13 and the lower mold 22 decreases. At this time, the outer surface of the bottom end of the connecting rod 255 slides into the groove 2511 inside the pressure block 251, and the cross bar at the bottom end of the connecting rod 255 engages with the groove 2511. The fixed plate 253 is fixedly connected to the upper surface of the workbench 21, and the fixed plate 253 and the pressure block 251 are connected by the tension spring 252. When the bottom end of the connecting rod 255 enters the groove 2511, the pressure block 251 moves toward the fixed plate 253 according to the trajectory of the slide groove 212 under the action of the tension spring 252, and restores its initial state (after positioning, the elastic member 254 is restored to its initial position to avoid the elastic member 254 being punched during the punching process of the plate. At the same time, it also avoids the elastic member 254 from affecting the upper mold 13 and the lower mold 22).

[0060] The process of punching the sheet metal:

[0061] At the same time, the lower surface of the upper die 13 begins to fit with the upper surface of the sheet, and the connecting rod 255 continues to press downward. Since the open ends on both sides of the groove 2511 are designed with curved surfaces, and the bottom end of the connecting rod 255 is located at the open end position of the groove 2511 (the width of the inclined surface of the pressing block 251 is greater than the width of the groove 2511, when the bottom end of the connecting rod 255 fits with the inner wall of the groove 2511, the connecting rod 255 is located at the curved surface position of the open end of the groove 2511), after the connecting rod 255 is subjected to force, its L-shaped bottom end slides out from the side to the outside of the pressing block 251, and is in a slightly tilted state. The upper die 13 and the lower die 22 cooperate with each other, and under the action of the crankshaft 15 and the connecting rod, the sheet is instantly punched. After the punching is completed, the sheet moves away from the base frame 231 under the action of the lower roller 232. After the punching is completed, the sheet is unloaded by the external unloading cylinder.

[0062] In summary, the above-mentioned process of loading, correction and punching has the following advantages:

[0063] Advantage 1: During the loading process, a double-layer conveyor is set in the loading part 23, which is divided into two layers, the upper roller 236 and the lower roller 232. The upper roller 236 and the lower roller 232 rotate in opposite directions and are both electrically controlled, and can convey the plate between the upper roller 236 and the lower roller 232 to the lower module 22.

[0064] Advantage 2: The top frame 235 and the bottom frame 231 are rotatably connected through two connecting rods 233. Taking one side as an example, a parallelogram structure is formed between the top frame 235, the bottom frame 231 and the two connecting rods 233. The horizontal section of the top frame 235 always remains parallel to the bottom frame 231, and can clamp the upper and lower sides of the plate to prevent the plate from warping and deformation.

[0065] Advantage three: the adjusting member 24 can adjust the height of the lower die 22 through the inclination angle of the connecting rod 233, that is, the thickness of the plate. If the plate is thin and the punching force is met, the height of the lower die 22 does not need to be adjusted. The thicker the plate, the larger the angle between the connecting rod 233 close to the lower die 22 and the base frame 231 becomes (no more than ninety degrees at most). The greater the rotation degree of the gear 246 fixedly connected to the outer surface of the connecting rod 233, the transmission gear 245 and the worm 244 are driven to rotate. The worm gear 243 sleeved on the outer end of the double-headed threaded rod 241 engages with it and rotates synchronously, and finally squeezes the wedge blocks 242 on both sides towards the lower die 22 at the same time. The oblique edge of the wedge block 242 converts the horizontal force into the vertical direction, so that the lower die 22 moves upward for a distance, thereby reducing the distance between the upper die 13 and the lower die 22. During this process, the height of the lower die 22 can be adjusted according to the different thicknesses of the plates to meet the requirement that the thicker the plate, the greater the punching force required (when the distance between the upper die 13 and the lower die 22 decreases, the mold closing speed remains unchanged, and the plate is compressed or formed in a shorter time, which means that the force acting on the plate will be more concentrated, resulting in an increase in the impact force).

[0066] Advantage 4: The connecting rod 255 in the horizontal positioning member 25 is set on the lower surface of the slider 12. The length of the connecting rod 255 is greater than the thickness of the upper mold group 13. Before the stamping part 1 stamps the plate, the connecting rod 255 is pressed down to move the pressure blocks 251 on both sides toward the middle lower mold group 22, so as to correct the position of the plate on the upper surface of the lower mold group 22.

[0067] Advantage 5: The elastic member 254 is composed of multiple longitudinally distributed curved strips. This ensures that when the lower die 22 is at different heights, there is always a curved strip that is higher than the lower die 22. The outer surface of the curved strip that is higher than the upper surface of the lower die 22 is in contact with the plate. At the same time, alignment and correction are performed from both sides to meet the needs of using lower dies 22 at different heights. After correction is completed, the connecting rod 255 engages with the interior of the groove 2511, and the pressure block 251 is reset by the action of the tension spring 252, avoiding damage to the elastic member 254 during the stamping process and avoiding inaccurate stamping precision caused by the elastic member 254 being located between the upper die 13 and the lower die 22.
