Description

Technical Field

[0001] This invention belongs to the field of mechanical equipment technology, and specifically discloses a plate processing device for preparing pressure-bearing heads. Background Technology

[0002] In the manufacturing process of pressure-bearing heads (such as pressure vessel heads and storage tank heads), the first step is to cut a large sheet of metal into a circular or elliptical blank according to the head design. Currently, the industry commonly uses gantry-type CNC cutting equipment or XY-axis transverse sawing machines. These devices typically include: a gantry spanning the width of the sheet, a sawing head (circular saw blade or band saw) mounted on the gantry, and a servo drive system that drives the sawing head to move in the X (transverse) and Y (feed) directions. During cutting, the sheet is placed on a worktable, and the cutting head moves to complete the cutting process.

[0003] However, the aforementioned conventional gantry sawing equipment suffers from the following significant technical problems when processing large-sized thin plates used for pressure-bearing heads: Large-sized thin plates (large aspect ratio, small thickness) have poor rigidity. During sawing, the plate around the cutting area lacks effective support, especially when the saw head moves to the middle or edge of the plate, where it is prone to local collapse under its own weight and the pressure of sawing. Collapse leads to a sharp narrowing of the kerf, causing the saw blade to clamp, or even chip or break, severely affecting cutting safety and continuous processing capacity. Existing devices use very simple methods to fix thin plates: either relying solely on the plate's own weight to press it onto the table, or using several independent pneumatic pressure blocks to apply pressure to the edges. Due to the large area and low rigidity of large-sized thin plates, edge pressing cannot suppress vibration and displacement in the middle of the plate. During high-speed sawing, the plate will exhibit significant chatter and lateral movement. Furthermore, multiple independent pressure blocks require repeated manual adjustments and cannot achieve dynamic fixation following the sawing path, severely restricting automation and production efficiency.

[0004] Therefore, there is an urgent need to provide a plate processing device for the preparation of pressure-bearing heads, which can effectively suppress plate collapse, control cutting deformation, and achieve reliable dynamic fixation near the cutting area during the sawing process of large-size thin plates, thereby improving the blanking accuracy and processing stability of the head blanks. Summary of the Invention

[0005] The purpose of this invention is to solve the problems existing in the background art, and to propose a plate processing device for preparing pressure-bearing heads, comprising two supports, a worktable and an electric saw. A Y-axis ball screw drive device is fixedly installed above each of the two supports. An X-axis ball screw drive device is jointly arranged above the two Y-axis ball screw drive devices. A slide block is laterally driven outside the X-axis ball screw drive device. A sawing mechanism is arranged outside the slide block. Two sets of plate-stabilizing and pressing mechanisms are correspondingly connected to both ends of the worktable via bidirectional drive mechanisms. The two sets of plate-stabilizing and pressing mechanisms include a slide frame slidably installed outside one side of the worktable. One end of the two bidirectional drive mechanisms on the same side is connected to the outer wall of one side of the slide frame. A reciprocating mechanism is arranged inside the slide frame. A slide table is arranged outside the reciprocating mechanism. A frame is fixedly installed on the outer wall of one side of the slide table. Telescopic adjustment components are arranged on both sides inside the frame.

[0006] In the above technical solution, the sawing mechanism further includes a Z-axis lifting drive device, which is fixedly installed outside the slide block, and a frame is fixedly installed at the telescopic end of the Z-axis lifting drive device, and an electric sawing machine is installed on the outside of the frame.

[0007] In the above technical solution, the bidirectional drive mechanism further includes a mounting column, which is fixedly installed inside one end of the workbench, and a mounting groove is provided inside the mounting column. A bidirectional electric telescopic cylinder is fixedly embedded inside the mounting groove. One end of the bidirectional electric telescopic cylinder is connected to the outside of the slide. A clamping cylinder is installed at equal intervals along the horizontal direction at the upper end of the slide. A universal ball bearing is rotatably embedded in the upper part of the clamping cylinder.

[0008] In the above technical solution, the reciprocating mechanism further includes a motor, which is fixedly installed on the outside of one end of the slide, and a screw is fixedly installed on the output end of the motor. The end of the screw away from the motor is rotatably engaged with the inside of the slide, and the slide is threadedly sleeved on the outside of the screw, and the slide is slidably engaged with the inside of the slide.

[0009] In the above technical solution, the telescopic adjustment component further includes an L-shaped base, a second cylinder is provided on the outer wall of one side of the L-shaped base, the end of the second cylinder away from the L-shaped base is connected to the inside of the frame, a first cylinder is fixedly installed on the inner surface of the L-shaped base, a clamping bracket is fixedly installed on the telescopic end of the first cylinder, and stabilizing wheels are rotatably installed on both sides inside the clamping bracket.

[0010] In the above technical solution, a movable seat is fixedly installed on one side of the slide table, a position sensor is fixedly installed on the upper surface of the movable seat, a third cylinder is fixedly installed on the top wall of the movable seat, a connecting frame is fixedly installed on the telescopic end of the third cylinder, and a pressure wheel is rotatably installed inside the connecting frame.

[0011] In the above technical solution, a bidirectional toothed frame is fixedly installed on one side of the connecting frame, and multiple toothed corners are installed on both sides of the bidirectional toothed frame. Rotating shafts are rotatably installed inside the movable seat and near both sides of the bidirectional toothed frame. Anti-slip curved plates are symmetrically fixedly sleeved on the outside of the two rotating shafts, and pressure rollers are fixedly installed at the lower ends of the two anti-slip curved plates.

[0012] In the above technical solution, a gear is further fixedly sleeved on one end of the rotating shaft, and the gear meshes with multiple tooth angles on the outside of the corresponding bidirectional gear frame. A disc is fixedly installed on one end of the pressure roller.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting two opposing telescopic adjustment components inside the frame, effective top pressure support can be provided to the plate below the cutting area during the sawing of large-size thin plates. This significantly suppresses the local collapse caused by the combined effect of the plate's own weight and the sawing pressure, avoids narrowing of the saw kerf and saw blade clamping, and ensures cutting safety and continuous processing capability.

[0014] 2. Through the coordinated action of the bidirectional drive mechanism and the reciprocating mechanism, the clamping component and the sawing path can be followed in real time. Dynamic and multi-point stable constraints can be applied at different cutting positions of the plate, effectively controlling cutting deformation and meeting the high-precision sawing requirements of the pressure-bearing head.

[0015] 3. By setting a movable seat on one side of the slide table, the plate can be pressed against from above during sawing. Through the linkage of the bidirectional gear frame and gears, the disc is pressed against one side of the plate, and the pressing roller achieves a pressing effect on the upper surface of the plate, reducing the generated chatter and lateral movement, significantly improving the stability of the cutting process and the quality of the cut. The entire pressing and supporting process does not require repeated manual adjustment of the position, realizing automated and follow-up plate fixing, greatly improving the production efficiency and automation level of the equipment, and reducing the labor intensity of operators.

[0018] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0020] like Figures 1-7 The plate processing device shown includes two supports 1, a worktable 2, and an electric sawing machine 9. A Y-axis ball screw drive device 5 is fixedly installed above each of the two supports 1. An X-axis ball screw drive device 3 is commonly installed above the two Y-axis ball screw drive devices 5. A slide 6 is laterally driven outside the X-axis ball screw drive device 3. A sawing mechanism is installed outside the slide 6. Two sets of plate-stabilizing and pressing mechanisms are connected to both ends of the worktable 2 via bidirectional drive mechanisms. Each set of plate-stabilizing and pressing mechanisms includes a slide frame 12 slidably installed on one side of the worktable 2. One end of each of the two bidirectional drive mechanisms on the same side is connected to the outer wall of one side of the slide frame 12. A reciprocating mechanism is installed inside the slide frame 12. A slide table 16 is installed outside the reciprocating mechanism. A frame 14 is fixedly installed on the outer wall of one side of the slide table 16. Telescopic adjustment components are installed on both sides inside the frame 14.

[0021] In this embodiment, after the large-sized thin plate to be processed is placed on the worktable 2, the control system first activates the bidirectional drive mechanism, pushing the slides 12 on both sides towards the center of the worktable 2 to perform initial centering and limiting of the plate. Subsequently, the sawing mechanism, driven by the X-axis ball screw drive device 3 and the Y-axis ball screw drive device 5, cuts according to a preset trajectory. At the same time, the plate stabilizing and pressing mechanisms on both sides work synchronously: the bidirectional drive mechanism drives the slides 12 to move along the Y-axis direction according to the Y-axis coordinate of the sawing point, so that the entire mechanism always stays near the cutting area. The reciprocating mechanism inside the slides 12 drives the slide table 16 to move precisely along the X-axis direction, sending the frame 14 and its internal telescopic adjustment components to directly below the sawing point or a designated support point. After reaching the position, the telescopic adjustment components extend from under the plate, providing active support force to the cutting area, thereby suppressing the local collapse of the plate caused by its own weight and cutting pressure.

[0022] In summary, this technology enables precise and real-time following support below the cutting area of ​​the sheet metal. Compared with existing technologies, its advantages lie in effectively solving the problem of local collapse caused by insufficient rigidity during the sawing of large-sized thin plates, avoiding the risks of narrowing the kerf and saw blade clamping, significantly improving the safety and continuous processing capability of the cutting process, and laying the foundation for further improving cutting accuracy.

[0023] The sawing mechanism includes a Z-axis lifting drive device 8, which is fixedly installed outside the slide block 6, and a frame is fixedly installed at the telescopic end of the Z-axis lifting drive device 8. An electric sawing machine 9 is installed on the outside of the frame.

[0024] In this embodiment, during the cutting preparation stage and the cutting process, the Z-axis lifting drive device 8, driven by the external control system, causes its extension end to move linearly in the vertical direction. When cutting is required, the Z-axis lifting drive device 8 extends, driving the frame and electric saw 9 to descend to the preset cutting depth; when cutting is completed or when idle movement is required, the Z-axis lifting drive device 8 retracts, driving the sawing mechanism to rise, causing the saw blade to detach from the board and avoid interference.

[0025] The bidirectional drive mechanism includes a mounting column 4, which is fixedly installed inside one end of the workbench 2. The mounting column 4 has a mounting groove inside, and a bidirectional electric telescopic cylinder 7 is fixedly embedded inside the mounting groove. One end of the bidirectional electric telescopic cylinder 7 is connected to the outside of the slide 12. The upper end of the slide 12 is equipped with clamps 15 at equal intervals along the horizontal direction. Universal ball bearings 13 are rotatably embedded inside the upper part of the clamps 15.

[0026] In this embodiment, the control system controls the extension and retraction of the bidirectional electric telescopic cylinder 7 according to the width of the board and the sawing path. When the bidirectional electric telescopic cylinder 7 extends, it pushes the slide 12 and the clamping sleeve 15 and universal ball bearings 13 on the slide to move towards the edge of the board in the middle of the worktable 2, clamping the board from both sides to achieve positioning. During the sawing process, when the slide 12 moves with the sawing point, the bottom surface of the board contacts the universal ball bearings 13, which can roll flexibly, converting sliding friction into rolling friction.

[0027] By setting multiple omnidirectional ball bearings 13 above the carriage 12, low-friction rolling support is provided for the moving large-sized sheet metal. The beneficial effect is that it ensures the smooth movement of the sheet metal in the Y direction, prevents scratches on the sheet metal surface, and provides auxiliary support for the sheet metal, reducing the risk of deformation caused by the large size of the sheet metal being suspended in the air.

[0028] The reciprocating mechanism includes a motor 10, which is fixedly installed on the outside of one end of the slide 12. A screw 17 is fixedly installed on the output end of the motor 10. The end of the screw 17 away from the motor 10 is rotatably engaged with the inside of the slide 12. The slide table 16 is threadedly sleeved on the outside of the screw 17, and the slide table 16 is slidably engaged with the inside of the slide 12.

[0029] In this embodiment, when it is necessary to fine-tune the position of the frame 14 in the X-axis direction, the control system starts the motor 10. The output shaft of the motor 10 rotates, driving the screw 17 to rotate synchronously. Since the slide 16 is threadedly connected to the screw 17, and the slide 16's rotational freedom is restricted by the carriage 12, the rotational motion of the screw 17 is converted into the linear reciprocating motion of the slide 16 along the interior of the carriage 12. The direction of movement of the slide 16 is determined by the rotational direction of the motor 10, and the speed of movement is determined by the rotational speed of the motor 10.

[0030] Through the above structure, the slide table 16 and its frame 14 can be driven accurately and quickly to the X coordinate position below the sawing point, so as to achieve precise synchronous following between the support point and the cutting point, and provide accurate positioning for the telescopic adjustment component.

[0031] The telescopic adjustment assembly includes an L-shaped base 21. A second cylinder 19 is provided on the outer wall of one side of the L-shaped base 21. The end of the second cylinder 19 away from the L-shaped base 21 is connected to the inside of the frame 14. A first cylinder 18 is fixedly installed on the inner surface of the L-shaped base 21. A clamping frame 20 is fixedly installed on the telescopic end of the first cylinder 18. Stable wheels 22 are rotatably installed on both sides inside the clamping frame 20.

[0032] In this embodiment, after the frame 14 moves below the cutting point, the second cylinder 19 extends first, pushing the L-shaped base 21 horizontally towards the lower surface of the board. Then, the first cylinder 18 extends, driving the clamping bracket 20 on its telescopic end to rise vertically until the stabilizing wheels 22 on both sides inside the clamping bracket 20 press tightly against the lower surface of the board, providing upward support. Since the stabilizing wheels 22 are rotatably mounted, they can rotate with the relative movement of the board during cutting, providing support without hindering the movement of the board. After cutting, the first cylinder 18 and the second cylinder 19 retract sequentially, causing the stabilizing wheels 22 to disengage from the lower surface of the board.

[0033] The stabilizing wheel 22 acts directly below the sawing area, providing the most effective local anti-collapse support; at the same time, the rotating design of the stabilizing wheel 22 avoids sliding friction between the support and the sheet, preventing damage to the sheet surface and ensuring smooth follow-up movement.

[0034] A movable seat 11 is fixedly installed on one side of the slide table 16. A position sensor 32 is fixedly installed on the upper surface of the movable seat 11. A third cylinder 31 is fixedly installed on the top wall of the movable seat 11. A connecting frame 25 is fixedly installed on the telescopic end of the third cylinder 31. A pressure wheel 26 is rotatably installed inside the connecting frame 25. A bidirectional gear frame 24 is fixedly installed on one side of the connecting frame 25. Multiple tooth angles are installed on both sides of the bidirectional gear frame 24. Rotating shafts 30 are rotatably installed inside the movable seat 11 and on both sides near the bidirectional gear frame 24. Anti-slip curved plates 29 are symmetrically fixedly sleeved on the outside of the two rotating shafts 30. Pressure rollers 28 are fixedly installed on the lower ends of the two anti-slip curved plates 29. A gear 23 is fixedly sleeved on the outside of one end of the rotating shaft 30. The gear 23 meshes with multiple tooth angles on the outside of the corresponding bidirectional gear frame 24. A disc 27 is fixedly installed on the outside of one end of the pressure roller 28.

[0035] In this embodiment, after the slide table 16 drives the movable seat 11 to move to the predetermined position following the sawing point, the third cylinder 31 is activated, and its telescopic end extends downward, pushing the connecting frame 25 and the pressure roller 26 rotatably installed therein to move vertically downward. This is the first pressing, with the pressure roller 26 pressing directly against the upper surface of the plate from above. At the same time, the bidirectional gear frame 24 fixed to one side of the connecting frame 25 also moves downward. The tooth angles on both sides of the bidirectional gear frame 24 drive the gears 23 meshing with it to rotate. Since the two gears 23 mesh with the tooth angles on both sides of the bidirectional gear frame 24 respectively, when the bidirectional gear frame 24 moves downward, the two gears 23 will obtain opposite rotation directions. The rotation of each gear 23 will drive the rotating shaft 30 where it is located and the anti-slip curved plate 29 fixedly sleeved on the rotating shaft to swing inward synchronously, i.e., toward the upper end surface of the plate. The pressure roller 28 at the lower end of the anti-slip curved plate 29 and the disc 27 at its end will therefore apply pressure inward and downward from the upper sides of the plate. This is the second layer of compression; the pressure roller 28 and the disc 27 provide auxiliary pressure on the side wall and upper surface of the board, respectively, to further enhance the constraint on the board.

[0036] During this process, position sensor 32 is used to detect the position of the sawing point in real time to ensure that the entire clamping action is triggered at the correct time and position. After the cutting is completed, the third cylinder 31 retracts, pulling the connecting frame 25 and the bidirectional gear frame 24 upward. Through the linkage of gear 23 and anti-slip curved plate 29, the pressure roller 28 and disc 27 open outward, while the pressure roller 26 rises to release all clamping.

[0037] The vertical pressure of the pressure roller 26 effectively suppresses the vertical vibration of the board during high-speed sawing; the auxiliary pressing of the pressure roller 28 and the disc 27 further restricts the lateral movement and warping of the board, achieving all-round dynamic constraint on the cutting area.

[0038] It should be noted that the external control system can be a programmable logic controller (PLC), an embedded motion controller, or a CNC-based numerical control system commonly used in the field of industrial automation.

[0039] Working Principle: First, the large-sized thin sheet material to be processed is placed stably on the worktable 2. The chucks 15 installed at both ends of the worktable 2 and the universal ball bearings 13 above them assist in the flexible horizontal adjustment of the sheet material, reducing friction during movement. The operator activates the bidirectional electric telescopic cylinder 7 embedded inside the mounting column 4 via the control system. Simultaneously, the bidirectional electric telescopic cylinder 7 pushes the slides 12 on both sides towards the center along the outer side of the worktable 2, causing the universal ball bearings 13 above the slides 12 to approach the edge of the sheet material from both sides, completing the initial centering and limiting of the sheet material, preventing overall displacement during subsequent processing. Based on the preset cutting requirements of the end cap blank, the control system calculates and plans the linkage motion trajectory of the X-axis ball screw drive device 3 and the Y-axis ball screw drive device 5. The two Y-axis ball screw drive devices 5 are respectively fixed above the two supports 1, jointly supporting and driving the X-axis ball screw drive device 3 to feed along the Y-axis direction; the X-axis ball screw drive device 3, in turn, drives the external slide 6 to move along the X-axis direction. The Z-axis lifting drive device 8, which is fixed externally to the slide 6, drives the frame and the electric saw 9 to perform vertical lifting and lowering movements in the Z-axis direction for cutting and retraction. The three work together to enable the electric saw 9 to accurately cut the board according to a predetermined trajectory.

[0040] During the movement of the electric sawing machine 9 along the cutting path, in order to suppress the local collapse of the board caused by its own weight and the sawing pressure, two sets of plate stabilizing and pressing mechanisms dynamically follow and support the board synchronously. The bidirectional electric telescopic cylinders 7 on both sides control the slide 12 to move synchronously along the Y-axis direction according to the real-time Y-axis coordinate of the electric sawing machine 9, so that the slide 12 always stays in the area near the sawing point. When the slide 12 moves into place, the motor 10 inside the slide 12 starts and drives the screw 17 to rotate. The slide table 16, which is threaded onto the screw 17, slides back and forth along the X-axis direction inside the slide 12, thereby driving the frame 14 outside the slide table 16 to move precisely to the support point directly below the electric sawing machine 9 or on the sawing path. The telescopic adjustment components set on both sides inside the frame 14 start to work. First, the second cylinder 19 pushes the L-shaped base 21 to extend towards the lower surface of the plate. Then, the first cylinder 18, installed on the inner surface of the L-shaped base 21, drives the clamping frame 20 to rise further, causing the stabilizing wheels 22, rotatably mounted on both sides inside the clamping frame 20, to press tightly against the lower surface of the plate. The stabilizing wheels 22 employ a rotating design, allowing relative rolling at the cutting position of the plate while providing pressure support, avoiding contact and obstruction with the plate. At this time, the stabilizing wheels 22 provide active support force to the sawing area from below, effectively counteracting the collapse caused by downward pressure and gravity, preventing narrowing of the kerf and saw blade clamping.

[0041] To further suppress chatter and lateral movement of the sheet metal during high-speed sawing, a movable seat 11 fixedly installed on one side of the slide table 16 performs the following actions simultaneously: a position sensor 32 fixedly installed on the upper surface of the movable seat 11 detects the position of the sawing point in real time. When the movable seat 11 moves to the set position with the slide table 16, the third cylinder 31 is activated, and its telescopic end pushes the connecting frame 25 and the pressure roller 26 rotatably installed inside the connecting frame 25 downward, so that the pressure roller 26 presses the upper surface of the sheet metal from above, forming a stable constraint in the vertical direction. At the same time as the third cylinder 31 pushes the connecting frame 25 down, the bidirectional gear frame 24 fixedly installed on one side of the connecting frame 25 moves downward simultaneously. Multiple teeth on both sides of the bidirectional gear frame 24 mesh with gears 23 on the rotating shafts 30 on both sides inside the movable seat 11, driving the two gears 23 to rotate in opposite directions. Gear 23 drives the rotating shaft 30 and the externally symmetrically fixed anti-slip curved plates 29 to swing inward, thereby applying a robust counter-pressure from the upper surface of the board to the pressure rollers 28 at the lower end of the two anti-slip curved plates 29 and the disc 27 on the outer side of one end of the pressure rollers 28. The auxiliary reinforcement and the vertical pressure of the counter-pressure rollers 26 firmly fix the board near the sawing area. After all the pressing and supporting structures are in place, the Z-axis lifting drive device 8 controls the electric sawing machine 9 to descend to the set cutting depth. The electric sawing machine 9 starts to rotate the saw blade, and at the same time, the X-axis ball screw drive device 3 and the Y-axis ball screw drive device 5 feed in linkage according to the preset trajectory. During the sawing process, the board stabilizing and counter-pressure mechanism slide 12, slide table 16, frame 14 and its internal telescopic adjustment components and the pressing and clamping components on the moving seat 11, the counter-pressure rollers 26, pressure rollers 28 and discs 27 always move synchronously with the sawing point of the electric sawing machine 9 to ensure dynamic real-time constraint on the cutting area. The omnidirectional ball bearing 13 continuously provides rolling support to the plate during the movement of the carriage 12, reducing frictional resistance.

[0042] After a blank end cap is cut, the Z-axis lifting drive 8 drives the electric saw 9 to rise and retract the blade. Subsequently, the first cylinder 18 and the second cylinder 19 retract sequentially, causing the stabilizing wheel 22 to disengage from the lower surface of the sheet metal. The third cylinder 31 retracts, driving the pressure wheel 26 to rise and release the vertical clamping. Simultaneously, the bidirectional gear frame 24 moves upward, driving the anti-slip curved plate 29 to swing in the opposite direction via the gear 23, causing the pressure roller 28 and the disc 27 to loosen their grip on the side of the sheet metal. The bidirectional electric telescopic cylinder 7 controls the slide 12 to move outward, releasing the overall limit. This completes one processing cycle. The operator can then remove the cut end cap blank and place the next sheet metal, repeating the above steps for continuous production.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
