[0029] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0030] like Figures 1 to 7As shown in the embodiment of the present invention, a metal sheet shearing machine includes a shearing machine base 1; a servo motor 11 is fixedly connected to the top surface of the middle part of the shearing machine base 1; a fixing block 12 is fixedly connected to the output end of the servo motor 11; side brackets 13 are fixedly connected to both sides of the fixing block 12; fixing frames 14 are fixedly connected to both ends of the two side brackets 13; suction cup frames 15 are provided on the sides of the multiple fixing frames 14; a pump suction mechanism is provided on the fixing block 12, which is used for vacuum adsorption of the metal sheet; a disc blade 16 is provided on the shearing machine base 1; a shearing assembly is provided on the shearing machine base 1, which is used to cooperate with the disc blade 16 to cut the metal sheet; when shearing the metal sheet, the shearing machine base 1 serves as the main structure of the metal sheet shearing machine, the two fixing frames 14 are respectively fixed to the ends of the two side brackets 13 on both sides of the fixing block 12, and the two adjacent suction cup frames 15 first cooperate with the pump suction mechanism to vacuum adsorb a piece of metal sheet. As the output of the servo motor 11 drives the fixed block 12 to rotate 180 degrees, the vacuum-adsorbed metal sheet is sent to the shearing assembly. The shearing assembly, in conjunction with the disc cutter 16, performs a cutting operation on the sheet. Simultaneously, two suction cups 15, located close to each other on the other ends of the two side supports 13, vacuum-adsorb another metal sheet. After the previous metal sheet is cut, the output of the servo motor 11 synchronously drives both the cut and uncut metal sheets to rotate 90 degrees. At this point, the suction of the cut metal sheet stops, and the output of the servo motor 11 rotates 90 degrees again. The uncut metal sheet is placed at the shearing assembly for cutting, while the two suction cups 15 vacuum-adsorb a new metal sheet again. This continuous synchronous operation ensures the coordination of the loading and unloading mechanical actions, reduces the possibility of inaccurate positioning of the sheet and resulting in cutting deviations, and decreases the probability of jamming and stopping in the automated shearing machine.

[0031] like Figure 1 , Figures 3 to 6As shown, the pump suction mechanism includes an electric actuator 2, a limiting frame 21, a connecting box 22, air pipes 23, a distance adjustment assembly, a connecting assembly, and a control assembly. The electric actuator 2 is fixed to the top of the fixed block 12. The limiting frame 21 is fixed to the output end of the electric actuator 2. The connecting box 22 is fixed to the top of the middle part of the limiting frame 21. Four air pipes 23 are fixed to the four corners of the connecting box 22, and the connecting box 22 can be connected to the suction cup frame 15 through the air pipes 23. Multiple distance adjustment assemblies are respectively set on multiple fixed frames 14. The distance adjustment assemblies are used to adjust the distance between two suction cup frames 15, and the suction cup frames 15 are mounted on the fixed frames 14 through the distance adjustment assemblies. The connecting assembly is set on the shearing machine base 1, and the connecting assembly is located above the connecting box 22. The connecting assembly is used to connect with the connecting box 22 to control the pump suction of the suction cup frame 15. The control assembly is set on the connecting box 1. The control component, located on the upper surface of the connecting box 22, controls the loading and unloading of the metal sheet. When the metal sheet is pumped, the output end of the electric actuator 2 first drives the limit frame 21 to slide upward. Multiple air pipes 23 connect multiple suction cup frames 15 to the connecting box 22. After the metal sheet is placed under the multiple suction cup frames 15, the distance adjustment component first adjusts the position of the multiple suction cup frames 15 so that the multiple suction cup frames 15 can stably adsorb the metal sheet. The output end of the electric actuator 2 drives the limit frame 21 to slide downward, so that the multiple suction cup frames 15 press against the upper surface of the metal sheet. The connecting box 22 then cooperates with the connecting component to start pumping. The multiple suction cup frames 15 vacuum adsorb the metal sheet below it. 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, realizing the loading and unloading of the metal sheet and playing the role of pumping the metal sheet.

[0032] like Figure 1 , Figure 3 and Figure 4 As shown, the distance adjustment assembly includes a sliding frame 3 and a connecting cylinder 31. The sliding frame 3 is slidably connected to the fixed frame 14 via a first electric slider. The connecting cylinder 31 is fixed to the end of the sliding frame 3 away from the fixed frame 14, and the suction cup frame 15 is slidably connected to the inner wall of the connecting cylinder 31. When pumping metal sheets of different lengths, the adsorption stability of the adsorption points of 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 multiple suction cup frames 15 to slide upwards on the inner wall of the connecting cylinder 31. The first electric slider on the fixed frame 14 drives the sliding frame 3 to slide, adjusting the distance between the two suction cup frames 15 to find the stable adsorption point of the currently adsorbed metal sheet. At this time, the output end of the electric push rod 2 drives multiple suction cup frames 15 to slide downwards on the inner wall of the connecting cylinder 31, and presses the multiple suction cup frames 15 onto the upper surface of the metal sheet, controlling the two suction cup frames 15 to vacuum adsorb the metal sheet, thereby achieving the effect of stable adsorption of metal sheets of different lengths.

[0033] like Figures 1 to 6As shown, the connecting assembly includes a support plate 4, an air pump 41, a first flow control cylinder 42, and a second flow control cylinder 43. The support plate 4 is fixed to the outer wall of the shearing machine base 1. The air pump 41 is fixed to the support plate 4 and is located directly above the connecting box 22. The first flow control cylinder 42 is fixed to the output end of the air pump 41. The second flow control cylinder 43 is fixed to the upper surface of the connecting box 22, and the air pump 41 can be controlled by the first flow control cylinder 42 and the second flow control cylinder 43. The cylinders 43 are connected, and the first flow control cylinder 42 is rotatably connected to the inner wall of the second flow control cylinder 43. When pumping the metal sheet, the support plate 4 is fixed to the outer wall of the shearing machine base 1 to support the air pump 41. The air pump 41 serves as a power source to cooperate with the first flow control cylinder 42 to pump the second flow control cylinder 43. The second flow control cylinder 43 is connected to multiple suction cup frames 15 through multiple air pipes 23, so that the air pump 41 can cooperate with multiple suction cup frames 15 to pump and load multiple metal sheets synchronously.

[0034] The control component includes a connecting groove 5, air guide holes 51, and a sealing plate 52; two connecting grooves 5 are formed on the sealing plate 52; two air guide holes 51 are formed in the connecting grooves 5, and the first flow control cylinder 42 can be connected to the air pipe 23 through the air guide holes 51; the sealing plate 52 is fixedly attached to the sealing plate 52; when two metal sheets are adsorbed and transferred, one metal sheet is located below the shearing component for shearing, and the other metal sheet is located at the initial feeding point. The air pump 41 is connected to multiple air pipes 23 through the first flow control cylinder 42, the two connecting grooves 5, and multiple air guide holes 51 to realize the pumping of the two metal sheets; after the metal sheets are sheared, the servo motor 1 The output of 1 synchronously drives the sheared and unsheared metal sheets to rotate 90 degrees. At this time, the connecting groove 5 connected by multiple suction cup frames 15 on the sheared metal sheet is blocked by the sealing plate 52, stopping the adsorption of the sheared metal sheet. The other connecting groove 5 is still connected to multiple air pipes 23, which are close to it, to pump and realize the unloading of the sheared metal sheet. The output of servo motor 11 rotates 90 degrees again. The unsheared metal sheet is now placed at the shearing component for cutting. Both connecting grooves 5 are kept connected. After unloading, the two suction cup frames 15 vacuum adsorb the new metal sheet again. This cycle is repeated to realize the synchronous control of loading and unloading of metal sheets.

[0035] like Figures 1 to 3As shown, the shearing assembly includes a second electric slider 6, a blade holder 61, and a shearing table 62. The second electric slider 6 is slidably connected to the shearing machine base 1. The blade holder 61 is fixed to the outer wall of the second electric slider 6, and the disc blade 16 is slidably connected to the bottom of the blade holder 61 via a third electric slider. The shearing table 62 is fixed to the shearing machine base 1 and is located at the blade holder 61. When shearing a thin metal sheet, the thin metal sheet is pumped and transferred to the shearing table 62, and the shearing table 62 has a central opening. The cutting groove is directly opposite the disc cutter 16. As the second electric slider 6 drives the cutter holder 61 to slide down, the disc cutter 16 approaches the metal sheet. The disc cutter 16 has its own power source, which drives the disc cutter 16 to rotate rapidly. As the third electric slider drives the rotating disc cutter 16 to slide at the bottom of the cutter holder 61, it can cut and shear the metal sheet on the shearing table 62. After shearing, the two suction cups 15 pump the two cut metal sheets respectively, which plays the role of shearing the metal sheet.

[0036] like Figure 1 , Figure 3 and Figure 4 As shown, a telescopic rod 7 is fixedly connected to the outer wall of the suction cup frame 15; a short rod 71 is fixedly connected to the end of the telescopic rod 7 away from the suction cup frame 15; a pressure plate 72 is fixedly connected to the bottom end of the short rod 71; a support frame 73 is fixedly connected to one side of the fixed frame 14, and the end of the support frame 73 away from the fixed frame 14 is slidably connected to the outer wall of the short rod 71; when shearing a thin metal sheet, the cut edge of the thin metal sheet is prone to vibration, which affects the cut. 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 move with the output of the electric push rod 2. As the end slides down, the two suction cup frames 15 simultaneously drive the two short rods 71 ​​to slide down onto the inner walls of the two support frames 73. The two suction cup frames 15 and the two pressing plates 72 are all pressed onto the upper surface of the metal sheet cutting area. The two pressing plates 72 are pressed close to the cutting area of ​​the metal sheet to reduce the vibration of the metal sheet during shearing. At the same time, when cutting metal sheets of different lengths, as the suction cup frames 15 slide away from the pressing plates 72, the telescopic rod 7 is pulled and extended to connect the suction cup frames 15 and the short rods 71, so that the pressing plates 72 can slide up and down synchronously with the suction cup frames 15.

[0037] like Figure 1 , Figure 3 , Figure 5 and Figure 6As shown, a connecting frame 8 is fixed to the outer wall of the support plate 4; a first pressure sensor 81 is fixed to the outer wall of the connecting frame 8; and an extrusion block 82 is fixed to the outer wall of the second flow control cylinder 43. When cutting the metal sheet, the extrusion block 82 is fixed to the outer wall of the second flow control cylinder 43. As the output end of the servo motor 11 drives the extrusion block 82 on the second flow control cylinder 43 to rotate, the extrusion block 82 will extrude and trigger the first pressure sensor 81 fixed on the connecting frame 8 for each rotation. The first pressure sensor 81 then sends a signal to the main controller, which counts once. Each count determines that two metal sheets have been processed, thus serving as a count of the amount of metal sheet processed.

[0038] like Figure 1 , Figure 2 and Figure 7 As shown, a receiving platform 9 and a picking box 91 are fixedly connected to the upper surface of the shearing base 1, with the picking box 91 and the shearing platform 62 being arranged opposite each other. A sliding plate 92 is slidably connected to the inner wall of the picking box 91. A first elastic element 93 is fixedly connected to the bottom end of the sliding plate 92. When adsorbing, transferring, and shearing metal sheets, multiple metal sheets of the same type are first placed in the picking box 91. The picking box 91 can be replaced with the same type according to different types of metal sheets. Multiple metal sheets are pressed down on the sliding plate 92 by gravity, and the sliding plate 92 presses down on multiple first elastic elements 93 to contract and bear force. The topmost metal sheet is higher than the material box 91 by the thickness of one metal sheet. As each metal sheet is sucked away by the sliding plate 92, the weight on the sliding plate 92 decreases, and the bottom metal sheet is pushed up by the elastic force of multiple first elastic elements 93 to the height of one metal sheet on the sliding plate 92, which plays a role in assisting the feeding of the metal sheet. At the same time, the receiving table 9 is fixed on the shearing machine base 1 to temporarily place the sheared metal sheet. After the metal sheet is cut in half, it is transferred to the receiving table 9 for temporary storage, which facilitates the unloading of the sheared metal sheet.

[0039] A trigger box 94 is fixedly connected to the inner wall of the feeding box 91; a second pressure sensor 95 is fixedly connected to the inner wall of the trigger box 94; a trigger block 96 is slidably connected to the inner wall of the trigger box 94, and a protrusion is fixedly connected to the side of the trigger block 96 near the second pressure sensor 95; a second elastic element 97 is fixedly connected between the inner walls of the feeding box 91 and the trigger box 94; when multiple metal sheets are continuously fed into the feeding box 91, as multiple metal sheets are continuously picked up, the sliding plate 92 slides up and presses the trigger block 96 to slide on the inner wall of the trigger box 94, the second elastic element 97 is compressed and contracted, and the protrusion on the trigger block 96 presses and triggers the second pressure sensor 95, which then sends a signal to the main controller, which issues a warning signal to remind that the feeding of metal sheets in the feeding box 91 is about to end, thus indicating the need for replenishing materials.

[0040] Working process: When shearing thin metal sheets, the shearing machine base 1 serves as the main structure of the thin metal sheet shearing machine. Two fixed frames 14 are respectively fixed to the two ends of the two side supports 13 on both sides of the fixed block 12. Two adjacent suction cup frames 15 first work with the pump suction mechanism to vacuum-adsorb a thin metal sheet. As the output end of the servo motor 11 drives the fixed block 12 to rotate 180 degrees, the vacuum-adsorbed thin metal sheet is sent to the shearing assembly. The shearing assembly, in conjunction with the disc blade 16, performs the shearing operation on the thin sheet. At the same time, two adjacent suction cup frames 15 on the other end of the two side supports 13 vacuum-adsorb another thin metal sheet. After the first thin metal sheet is sheared, as the servo motor 11 outputs, the fixed block 12 rotates 180 degrees, sending the vacuum-adsorbed thin metal sheet to the shearing assembly. The shearing assembly, in conjunction with the disc blade 16, performs the shearing operation on the thin sheet. The output of the servo motor 11 synchronously drives the sheared and unsheared metal sheets to rotate 90 degrees. At this time, the sheared metal sheet stops being suctioned and fed. The output of the servo motor 11 rotates 90 degrees again, and the unsheared metal sheet is placed at the shearing assembly for cutting. The two suction cup frames 15 after feeding then vacuum-suction the new metal sheet again. This synchronous operation continues to ensure the coordination of the loading and unloading mechanical actions, reduce the situation where the sheet is difficult to accurately position and the cutting deviation occurs, and reduce the probability of the automated shearing machine jamming and stopping. When pumping the metal sheet, the output of the electric push rod 2 first drives the limit frame 21 to slide upward, and multiple air pipes 23 are distributed. Do not connect the multiple suction cup holders 15 to the connecting box 22. After the metal sheet is placed under the multiple suction cup holders 15, the adjusting component first adjusts the position of the multiple suction cup holders 15 so that the multiple suction cup holders 15 can stably adsorb the metal sheet. The output end of the electric push rod 2 drives the limiting frame 21 to slide down, so that the multiple suction cup holders 15 press against the upper surface of the metal sheet. The connecting box 22 then cooperates with the connecting component to start pumping. The multiple suction cup holders 15 vacuum adsorb the metal sheet below it. As the metal sheet is sheared, the control component controls the pumping effect of the suction cup holders 15 at both ends of the side bracket 13, realizing the loading and unloading of the metal sheet and playing the role of pumping the metal sheet; when different lengths When the metal sheet is pumped, the adsorption stability of the adsorption point of the metal sheet of different lengths is different. According to the different lengths of the metal sheet, the output end of the electric push rod 2 drives multiple suction cups 15 to slide upwards on the inner wall of the connecting cylinder 31. The first electric slider on the fixed frame 14 drives the sliding frame 3 to slide, and the distance between the two suction cups 15 is adjusted to find the stable adsorption point of the metal sheet being adsorbed. At this time, the output end of the electric push rod 2 drives multiple suction cups 15 to slide downwards on the inner wall of the connecting cylinder 31, and presses multiple suction cups 15 onto the upper surface of the metal sheet, controlling the two suction cups 15 to vacuum adsorb the metal sheet, so as to achieve the effect of stable adsorption of metal sheets of different lengths.

[0041] When pumping thin metal sheets, the support plate 4 is fixed to the outer wall of the shearing machine base 1, supporting the air pump 41. The air pump 41 acts as a power source, cooperating with the first flow control cylinder 42 to pump into the second flow control cylinder 43. The second flow control cylinder 43 is connected to multiple suction cup frames 15 through multiple air pipes 23, enabling the air pump 41 to cooperate with multiple suction cup frames 15 to pump and load multiple thin metal sheets simultaneously. When adsorbing and transferring two thin metal sheets, one thin metal sheet is located below the shearing assembly for shearing, while the other thin metal sheet is located at the initial loading point. The air pump 41 is connected to multiple air pipes 23 through the first flow control cylinder 42, two connecting slots 5, and multiple air guide holes 51 to achieve pumping of the two thin metal sheets. Waiting for the thin metal sheets to be loaded... After being sheared, the output of the servo motor 11 synchronously drives the sheared and unsheared metal sheets to rotate 90 degrees. At this time, the connecting groove 5 connected by multiple suction cup frames 15 on the sheared metal sheet is blocked by the sealing plate 52, stopping the adsorption of the sheared metal sheet. The other connecting groove 5 is still connected to multiple air pipes 23 that are close to it, and the sheared metal sheet is unloaded. The output of the servo motor 11 rotates 90 degrees again, and the unsheared metal sheet is placed at the shearing component for cutting. Both connecting grooves 5 remain connected. After unloading, the two suction cup frames 15 vacuum adsorb the new metal sheet again. This cycle is repeated to achieve the synchronous control of loading and unloading of metal sheets.

[0042] When shearing the metal sheet, the metal sheet is pumped and transferred to the shearing table 62. The shearing table 62 has a cutting groove in the middle, and the disc cutter 16 is directly opposite the cutting groove. As the second electric slider 6 drives the cutter holder 61 to slide down, the disc cutter 16 gets close to the metal sheet. The disc cutter 16 has its own power source, which drives the disc cutter 16 to rotate quickly. As the third electric slider drives the rotating disc cutter 16 to slide at the bottom of the cutter holder 61, it can cut the metal sheet on the shearing table 62. After shearing, the two suction cups 15 pump the two cut metal sheets respectively, which plays the role of shearing the metal sheet.

[0043] When shearing thin metal sheets, the cut edge is prone to vibration, affecting the cut. A 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 with the output end of the electric actuator 2, simultaneously driving the two short rods 71 ​​down onto the inner walls of the two support frames 73. The two suction cup frames 15 and the two pressing plates 72 press against the upper surface of the cut edge of the thin metal sheet. The two pressing plates 72 are close to the cut edge of the thin metal sheet, reducing vibration during shearing. Simultaneously, when cutting thin metal sheets of different lengths, as the suction cup frames 15 slide away from the pressing plates 72, the telescopic rod 7... The extended suction cup frame 15 and short rod 71 are connected, allowing the pressing plate 72 to 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. As the output 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 extrude and trigger the first pressure sensor 81 fixed on the connecting frame 8. The first pressure sensor 81 then sends a signal to the main controller, which counts once. Each count determines that two metal sheets have been processed, thus counting the amount of metal sheets processed. When the metal sheet is adsorbed, transferred, and sheared... First, multiple metal sheets of the same type are placed in the picking box 91. The picking box 91 can be replaced with the same type of metal sheet depending on the type of metal sheet. The multiple metal sheets are then pressed onto the sliding plate 92 by gravity. The sliding plate 92 presses down on multiple elastic elements 93, causing them to contract and bear force. The topmost metal sheet will be higher than the picking box 91 by the thickness of one metal sheet. As each metal sheet is picked up from the sliding plate 92, the weight on the sliding plate 92 decreases, and the bottommost metal sheet is pushed up by the elastic force of the multiple elastic elements 93, thus assisting in the feeding of the metal sheets. At the same time, the receiving platform 9 is fixed. The shearing base 1 is used to temporarily place the sheared metal sheets. After the metal sheets are cut in half, they are transferred to the receiving table 9 for temporary storage, which facilitates the unloading of the sheared metal sheets. When multiple metal sheets are continuously fed into the picking box 91, as multiple metal sheets are continuously picked up, the sliding plate 92 slides up and squeezes the trigger block 96 to slide on the inner wall of the trigger box 94. The second elastic element 97 is squeezed and contracted. The protrusion on the trigger block 96 squeezes and triggers the second pressure sensor 95. The second pressure sensor 95 then sends a signal to the main controller. The main controller issues a warning signal to remind that the feeding of metal sheets in the picking box 91 is about to end, thus indicating the need for replenishing materials.
