Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0041] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below with reference to the drawings and specific embodiments.

[0042] Reference Figure 1-4 The utility model provides a plate punching and forming device, comprising a conveying assembly and a frame 1, wherein the conveying assembly is used to convey a plate 2; the frame 1 is arranged at the output end of the conveying assembly; an adjustment assembly, a punching mechanism, a forming mechanism and a cutting assembly are installed on the frame 1 in sequence along the conveying direction of the plate 2;

[0043] The punching mechanism includes a punching bracket 12 and a hydraulic punching assembly. The punching bracket 12 is mounted on the frame 1, and the hydraulic punching assembly is mounted on the punching bracket 12;

[0044] The forming mechanism comprises a forming support 3, a plurality of forming rollers 4 and a plurality of feeding rollers 5; the forming support 3 is mounted on the frame 1, the plurality of forming rollers 4 and the plurality of feeding rollers 5 are rotatably connected to the forming support 3, the forming roller 4 is located directly above the feeding roller 5, and the plurality of forming rollers 4 and the plurality of feeding rollers 5 are arranged one by one; the tapers of the plurality of forming rollers 4 increase in sequence along the conveying direction of the plate 2;

[0045] A driving assembly is installed on the forming bracket 3, and a plurality of feeding rollers 5 are all connected to the driving assembly in a transmission manner; the forming bracket 3 is located between the punching bracket 12 and the cutting assembly; a control system 6 is installed on the frame 1, and the conveying assembly, the hydraulic punching assembly, the cutting assembly, and the driving assembly are all electrically connected to the control system 6; the control system 6 can be set according to the specific use environment, for example, it can be a single-chip microcomputer or controlled by PLC, ARM (Advanced RISC Machine: high-end reduced instruction set machine), FPGA (Field-Programmab le Gate Array: Field Programmable Gate Array) and other methods, which are not specifically limited in this embodiment;

[0046] With such arrangement, the utility model controls the operation of the hydraulic punching assembly through the control system 6 to realize accurate punching of the plate 2. The accurate control of the hydraulic punching assembly makes the punching position accurate and the punching depth consistent, greatly improving the punching accuracy, thereby improving the overall quality of the plate 2; the plate 2 can be accurately positioned and adjusted through the adjustment assembly to ensure that the plate 2 maintains the correct position and posture during the subsequent processing, thereby effectively improving the accuracy of punching and forming, and effectively avoiding quality problems caused by inaccurate position of the plate 2;

[0047] The utility model can realize accurate control of the conveying assembly, hydraulic punching assembly, cutting assembly and driving assembly through the control system 6, and the coordination between the various parts is closer, the degree of automation is higher, and the production efficiency is improved;

[0048] The utility model adopts a design of multiple groups of forming rollers 4 and feeding rollers 5. Through the change of the taper of the forming rollers 4 and the cooperation between the forming rollers 4 and the feeding rollers 5, the plate 2 is subjected to uniform force during the forming process, which effectively avoids the problem of cracking or deformation of the plate 2 and improves the forming effect.

[0049] The utility model conveys the plate 2 through the conveying component, and the plate 2 is adjusted and positioned by the adjustment component, punched by the hydraulic punching component, bent and formed by a plurality of forming rollers 4 and a plurality of feeding rollers 5, and cut by the cutting component, thereby realizing accurate positioning, efficient punching, optimized forming and accurate cutting of the plate 2, thereby realizing the automation and continuity of the plate 2 processing, and significantly improving the efficiency and quality of the plate 2 processing.

[0050] To further optimize the solution, the cutting components include:

[0051] A cutting bracket 7, which is mounted on the frame 1 and is located on a side of the forming bracket 3 away from the punching bracket 12;

[0052] A first hydraulic rod 8, which is mounted on the cutting support 7, with the piston end of the first hydraulic rod 8 facing the frame 1;

[0053] A cutting knife 9, which is mounted on the piston end of the first hydraulic rod 8;

[0054] A positioning plate 10, which is fixedly mounted on the cutting bracket 7, and has a positioning hole 11, and the cutting knife 9 is slidably connected to the outer wall of the positioning plate 10;

[0055] Wherein, the first hydraulic rod 8 is electrically connected to the control system 6;

[0056] With such arrangement, after the sheet 2 is formed by the forming mechanism, it is transported to the cutting assembly; at this time, the control system 6 issues a command to start the first hydraulic rod 8, and the piston end of the first hydraulic rod 8 begins to extend, driving the cutting knife 9 to move toward the frame 1; the cutting knife 9 maintains a sliding connection with the outer wall of the positioning plate 10 during the movement, ensuring that the movement trajectory of the cutting knife 9 is stable and accurate;

[0057] When the cutting knife 9 moves to the position of the positioning hole 11, the sheet 2 is accurately positioned below the cutting knife 9; at this time, the cutting knife 9 continues to press down to cut the sheet 2; after the cutting is completed, the piston end of the first hydraulic rod 8 retracts, driving the cutting knife 9 back to the initial position, ready for the next cutting;

[0058] During the entire cutting process, the positioning holes 11 on the positioning plate 10 play a crucial role. They ensure the accurate positioning of the sheet 2, thus guaranteeing the cutting precision. At the same time, the precise control of the first hydraulic rod 8 makes the cutting process stable and reliable, improving the cutting quality and efficiency.

[0059] For a further optimized solution, the hydraulic punching assembly includes:

[0060] A second hydraulic rod 13, which is installed on the punching bracket 12. The piston end of the second hydraulic rod 13 faces the frame 1;

[0061] A punching head 14, which is installed at the piston end of the second hydraulic rod 13;

[0062] A membrane seat 15, which is installed on the punching bracket 12 and is located directly below the punching head 14;

[0063] Among them, the second hydraulic rod 13 is electrically connected to the control system 6;

[0064] With such a setting, when the sheet 2 is conveyed to the punching position, the control system 6 issues an instruction to start the second hydraulic rod 13. The piston end of the second hydraulic rod 13 starts to extend, driving the punching head 14 to move towards the frame 1. During the movement of the punching head 14, it gradually approaches the sheet 2 until it contacts the sheet 2. At this time, the hydraulic punching assembly provides sufficient punching force to make the punching head 14 penetrate the sheet 2 to complete the punching action. After punching is completed, the piston end of the second hydraulic rod 13 retracts, driving the punching head 14 back to the initial position to prepare for the next punching;

[0065] The membrane seat 15 is located directly below the punching head 14 and is used to support the sheet 2 and prevent the deformation of the sheet 2 during punching. The design of the membrane seat 15 makes the punching process more stable and improves the punching precision.

[0066] For a further optimized solution, the adjustment assembly includes two oppositely arranged positioning wheels 17. The two positioning wheels 17 are installed on the frame 1 through a U-shaped bracket 16, and the sheet 2 extends into the punching bracket 12 along the interval between the two positioning wheels 17;

[0067] With such a setting, when the sheet 2 is fed into the equipment through the conveying assembly, it first contacts the two positioning wheels 17 of the adjustment assembly. The two positioning wheels 17 are oppositely arranged to form a fixed channel, and the sheet 2 extends into the punching bracket 12 along the interval between the two positioning wheels 17. Due to the guiding effect of the positioning wheels 17, the sheet 2 will automatically adjust its position during transportation to keep the interval between it and the positioning wheels 17 consistent, thereby enabling the sheet 2 to maintain the correct position and posture during subsequent processing.

[0068] Further optimized solution, the driving assembly includes two transmission rollers 18 arranged side by side, and the two transmission rollers 18 are rotatably connected to the forming bracket 3, and a reduction motor (not shown in the figure) is installed on the forming bracket 3, and the output shaft of the reduction motor is connected to one of the transmission rollers 18 through a coupling;

[0069] The two transmission rollers 18 are both equipped with first sprockets, which are connected by a chain 19. The feed roller 5 is equipped with second sprockets, which are meshed with the chain 19 for transmission. The reduction motor is electrically connected to the control system 6.

[0070] With such arrangement, when the reduction motor is started, its output shaft drives the transmission roller 18 to rotate, and drives several feed rollers 5 to rotate synchronously through the chain 19; thus, the sheet 2 can be acted upon by the forming roller 4 and the feed roller 5 during the forming process, thereby achieving precise bending and forming.

[0071] To further optimize the solution, the conveying components include:

[0072] A base 20, on which a support rod is mounted;

[0073] A driving shaft 21, the driving shaft 21 is rotatably connected to the support rod, and the plate 2 is wound around the driving shaft 21;

[0074] The feeding motor 22 is mounted on the base 20. The output shaft of the feeding motor 22 and the driving shaft 21 are both equipped with pulleys, and the two pulleys are connected by a transmission belt 23.

[0075] Among them, the feeding motor 22 is electrically connected to the control system 6;

[0076] With such arrangement, when the feeding motor 22 is started, its output shaft drives the pulley to rotate, and then drives the driving shaft 21 to rotate through the transmission belt 23; the rotation of the driving shaft 21 causes the plate 2 to move continuously on the conveying path, and is gradually conveyed from the starting position to each processing station.
