[0040] Working process: When shearing the metal sheet, the shearing machine base 1 is used as the main structure of the metal sheet shearing machine, and the two fixing frames 14 are respectively fixed at the two ends of the two side brackets 13 on both sides of the fixing block 12. The two adjacent suction cup frames 15 first cooperate with the pump suction mechanism to vacuum absorb a metal sheet. As the output end of the servo motor 11 drives the fixing block 12 to rotate 180 degrees, the vacuum-absorbed metal sheet is sent to the shearing component. The shearing component cooperates with the disc knife 16 to cut and shear the thin plate. At the same time, the two adjacent suction cup frames 15 at the other end of the two side brackets 13 vacuum absorb another metal sheet. After the shearing of the previous metal sheet is completed, the servo motor 11 drives the fixing block 12 to rotate 180 degrees, and ... The output end of the servo motor 11 synchronously drives the sheared and unsheared metal sheets to rotate ninety degrees. At this time, the sheared metal sheet stops adsorbing and unloading, and the output end of the servo motor 11 rotates ninety degrees again. The unsheared metal sheet is placed on the shearing assembly for cutting, and the two suction cup frames 15 after unloading vacuum adsorb the new metal sheet again. Such continuous synchronous operation ensures the coordination of the mechanical actions of loading and unloading, reduces the situation where the sheet is difficult to accurately position and the incision deviation occurs, and reduces the probability of the automatic shearing machine jamming and stopping. When the metal sheet is pumped, the output end of the electric push rod 2 first drives the limit frame 21 to slide up, and the multiple air pipes 23 are divided into The plurality of suction cup frames 15 are connected to the connecting box 22. After the metal sheet is placed under the plurality of suction cup frames 15, the distance adjustment component first adjusts the positions of the plurality of suction cup frames 15 so that the plurality of suction cup frames 15 can stably adsorb the metal sheet. The output end of the electric push rod 2 drives the limit frame 21 to slide down so that the plurality of suction cup frames 15 are pressed against the upper surface of the metal sheet. The connecting box 22 cooperates with the connecting component to start pumping. The plurality of suction cup frames 15 vacuum adsorb the metal sheet under them. As the metal sheet is sheared, the control component controls the pumping effect of the suction cup frames 15 at both ends of the side bracket 13 to realize the loading and unloading of the metal sheet and play the role of pumping the metal sheet. When the plurality of suction cup frames 15 are connected to the connecting box 22, the plurality of suction cup frames 15 are connected to the connecting box 22. When the metal sheet is pumped, the adsorption stability of the adsorption points of the metal sheets of different lengths is different. According to the different lengths of the metal sheets, the output end of the electric push rod 2 drives the multiple suction cup frames 15 to slide up on the inner wall of the connecting tube 31 first, and the No. 1 electric slider on the fixed frame 14 drives the sliding frame 3 to slide, and adjusts the distance between the two suction cup frames 15 to find the stable adsorption point of the currently adsorbed metal sheet.

After being sheared, the output end of the servo motor 11 synchronously drives the sheared and unsheared metal sheets to rotate ninety degrees. At this time, the connecting groove 5 connected to the multiple suction cup frames 15 on the sheared metal sheet is blocked by the blocking plate 52, and the adsorption of the sheared metal sheet is stopped. The other connecting groove 5 is still connected to the multiple air pipes 23 close to it to maintain pump suction, so as to realize the unloading of the sheared metal sheet; the output end of the servo motor 11 rotates ninety degrees again, and the unsheared metal sheet is placed at the shearing assembly for cutting.

[0042] When shearing the metal sheet, the metal sheet is pumped and transported to the shearing table 62. A cutting groove is provided in the middle of the shearing table 62, and the disc knife 16 is directly opposite to the cutting groove. As the No. 2 electric slider 6 drives the knife holder 61 to slide down, the disc knife 16 is close to the metal sheet. The disc knife 16 has a power source, which drives the disc knife 16 to rotate quickly. As the No. 3 electric slider drives the rotating disc knife 16 to slide at the bottom of the knife holder 61, the metal sheet on the shearing table 62 can be cut. After the shearing is completed, the two suction cup racks 15 pump the two sheared metal sheets respectively to play the role of shearing the metal sheets.

[0043] When shearing a metal sheet, the cutting part of the metal sheet is prone to shaking, thus affecting the incision. The telescopic rod 7 is fixed to the outer wall of the suction cup frame 15 and connected to the short rod 71. The two suction cup frames 15 slide down along with the output end of the electric push rod 2. The two suction cup frames 15 synchronously drive the two short rods 71 ​​to slide down on the inner walls of the two support frames 73. The two suction cup frames 15 and the two pressing plates 72 are pressed on the upper surface of the cutting part of the metal sheet. The two pressing plates 72 are pressed close to the cutting part of the metal sheet to reduce the shaking when the metal sheet is sheared. At the same time, when cutting metal sheets of different lengths, as the suction cup frame 15 slides away from the pressing plate 72, the telescopic rod 7 The suction cup frame 15 and the short rod 71 are pulled and stretched to connect, so that the pressing plate 72 can slide up and down synchronously with the suction cup frame 15; when cutting the metal sheet, the extrusion block 82 is fixed to the outer wall of the second flow control cylinder 43, and the output end of the servo motor 11 drives the extrusion block 82 on the second flow control cylinder 43 to rotate. Each rotation of the extrusion block 82 will squeeze and trigger the first pressure sensor 81 fixed on the connecting frame 8, and the first pressure sensor 81 sends a signal to the main controller, and the main controller counts once. Each count determines that two metal sheets are processed, which plays a role in counting the processing amount of the metal sheets; when the metal sheets are adsorbed, transported and sheared, First, place multiple metal sheets of the same type in the material picking box 91. The material picking box 91 can be replaced with the same type according to the different types of metal sheets. Multiple metal sheets are pressed onto the sliding plate 92 by gravity. The sliding plate 92 presses down multiple No. 1 elastic members 93 to contract and bear the force. The top metal sheet will be higher than the material picking box 91 by the thickness of a metal sheet. As a result, each time a metal sheet is sucked away from the sliding plate 92, as the gravity on the sliding plate 92 is reduced, the metal sheet at the bottom of the top is elastically pressed by multiple No. 1 elastic members 93 in combination with the sliding plate 92 to be as high as the thickness of a metal sheet on top of the sliding plate 92, thereby playing a role in assisting the loading of metal sheets. At the same time, the receiving table 9 is fixed on The shearing machine base 1 is used to temporarily store the sheared metal sheets. After the metal sheets are sheared in half, they are transferred to the receiving table 9 for temporary storage, which is convenient for unloading the sheared metal sheets. When multiple metal sheets in the material box 91 are continuously loaded, as multiple metal sheets are continuously picked up, the sliding plate 92 slides up to squeeze the trigger block 96 to slide on the inner wall of the trigger box 94, and the No. 2 elastic member 97 is squeezed and contracted. The protrusion on the trigger block 96 squeezes and triggers the No. 2 pressure sensor 95, and the No. 2 pressure sensor 95 sends a signal to the main controller, and the main controller sends a warning signal to remind that the metal sheets in the material box 91 are about to be loaded and the warning is to replenish the materials.
