Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, specifically to a continuous sheet metal cutting device. Background Technology

[0002] In sheet metal processing, continuous sheet metal cutting equipment is a key device for achieving batch cutting of sheet metal to a fixed length. Its cutting accuracy, continuous operation efficiency, and ease of operation directly affect the overall production capacity and product quality of sheet metal processing.

[0003] Existing sheet metal cutting devices generally suffer from the following problems: First, the lack of an automatic positioning and pad support mechanism linked to the conveying action during sheet metal cutting makes the sheet metal prone to skewed cuts due to positioning deviations. Furthermore, the pad needs to be manually reset after cutting, which cannot adapt to the continuous conveying rhythm and severely restricts cutting efficiency. Second, the cutting unit mostly relies on a single power source for lifting and lowering, requiring additional power for reset after cutting, which not only increases the complexity of the equipment structure but also increases energy consumption. Third, most devices cannot flexibly adjust the cutting length. When cutting sheet metal of different specifications and sizes, the positioning components need to be disassembled and reassembled, which is cumbersome and has low adjustment accuracy. Utility Model Content

[0004] The technical problem to be solved by this utility model is that existing plate cutting devices have large positioning deviations, low continuous cutting efficiency, cumbersome resetting of cutting units, and non-adjustable cutting length. The invention achieves linkage between plate conveying and positioning, automatic resetting of the pad, unpowered springback of the cutting unit, and flexible adjustment of cutting length, thereby improving cutting accuracy, continuous operation efficiency, and equipment versatility.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0006] A continuous plate cutting device includes a rotating frame with a drive roller rotating on it. A material plate is conveyed between the drive rollers. A gantry-type cutting frame is provided on one side of the rotating frame. A cutting table is provided at the bottom of the cutting frame. A stamping column connected to an external circulating lifting power mechanism is provided at the top. An automatic springback cutting unit is also provided between the inner walls of the cutting frame. When the stamping column is at its lowest position, it fits exactly with the cutting unit.

[0007] The cutting frame is provided with a connecting frame on the side away from the rotating frame. A linkage unit that rotatably engages with the end of the material plate is provided on the connecting frame. A rotating column is provided between the connecting frame and the rotating frame. A lifting and rebounding rotating cylinder is rotatably connected to the upper part of the rotating column. A pad is fixed at the top of the rotating cylinder. The linkage unit and the material plate work together to drive the pad to rotate between the stamping column and the cutting unit. When the material plate is cut, the pad automatically rotates to the outside of the cutting frame and is in the initial position.

[0008] As an improvement, the cutting unit includes a mounting plate that is lifted and disposed between the inner walls of the cutting frame. The two ends of the mounting plate are slidably connected to the grooves reserved in the inner wall of the cutting frame. A compression spring is connected between the bottom end of the groove and the bottom surface of the mounting plate. A cutter is provided in the middle of the bottom surface of the mounting plate. When the mounting plate is at its highest position, the bottom end of the cutter is close to the surface of the material plate.

[0009] As an improvement, the linkage unit includes a rotating seat mounted on the connecting frame. An inclined baffle is rotatably connected to the end of the rotating seat. The bottom end of the baffle is close to the end of the material plate, and the top part is away from the material plate. A top rod that is laterally slidably disposed on one side of the connecting frame is connected to the top of the baffle. The end of the top rod close to the cutting frame is slidably connected to the side wall of the pad. A telescopic spring is connected between the side wall of the connecting frame and the side wall of the pad.

[0010] As an improvement, the connecting frame is provided with a cutting length adjustment unit for adjusting the position of the rotating seat on the connecting frame. The cutting length adjustment unit includes a fixed shaft set at the end of the rotating seat, and the end of the fixed shaft passes through the movable groove reserved on the connecting frame and is threaded with a fixing bolt.

[0011] As an improvement, the upper part of the rotating column is provided with a central column that is rotatably connected to the inner wall of the rotating cylinder, and a spring is provided on the lower side of the bottom end of the rotating cylinder to surround the central column, with the bottom end of the spring being fixedly connected to the top of the rotating column.

[0012] As an improvement, the cutting table is provided with a slide fixed between the inner walls of the cutting frame on the side near the connecting frame. The slide is located directly below the material plate to be cut and is inclined from top to bottom, with its bottom end flush with the material plate collection station.

[0013] The advantages of this utility model compared with the prior art are as follows:

[0014] 1. This utility model achieves the linkage between material plate conveying positioning and automatic reset of the pad by cooperating with the linkage unit (baffle, top rod, telescopic spring) and pad and rebound spring: the material plate pushes the baffle to drive the pad to rotate to the cutting position. After cutting, the material plate is separated from the baffle, and the telescopic spring and rebound spring pull the pad to reset. No manual intervention is required, which perfectly matches the continuous conveying rhythm and significantly improves the continuous cutting efficiency.

[0015] 2. The cutting unit of this utility model uses a compression spring to achieve automatic rebound. During cutting, the cutting blade is driven by the downward pressure of the stamping column. After cutting, the compression spring directly pushes the mounting plate and the cutting blade to reset. No additional power source is required, which simplifies the equipment structure and reduces energy consumption.

[0016] 3. The cutting length adjustment unit of this utility model, through the cooperation of a fixed shaft, a moving groove, and a fixing bolt, allows the position of the rotating seat to be adjusted along the moving groove simply by loosening the bolt, thereby changing the positioning length of the material plate. The adjustment operation is convenient and highly accurate, and can adapt to the cutting needs of different specifications of plates. Attached Figure Description

[0025] The present invention will now be described in further detail with reference to the accompanying drawings.

[0026] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3 As shown, a continuous cutting device for sheet metal includes a rotating frame 1. Several transmission rollers 2 are rotatably mounted on the rotating frame 1 via deep groove ball bearings. Material sheets 3 (such as solid wood sheets, aluminum alloy sheets, and plastic sheets waiting to be cut) are conveyed between the transmission rollers 2. A portal-type cutting frame 4 is fixed to one side of the rotating frame 1 by bolts. A cutting table 5 is welded and fixed to the bottom of the cutting frame 4. A stamping column 6 is provided on the top of the cutting frame 4. An external circulating lifting power mechanism is connected to the top of the stamping column 6.

[0027] An automatic rebound cutting unit 7 is provided between the inner walls of the cutting frame 4. The two ends of the mounting plate 71 of the cutting unit 7 are slidably connected to the slide groove 72 reserved in the inner wall of the cutting frame 4. A compression spring 73 (a cylindrical spiral compression spring is selected to ensure that the mounting plate can be stably pushed back after cutting) is welded and fixed between the bottom end of the slide groove 72 and the bottom surface of the mounting plate 71. A cutter 74 is fixed in the middle of the bottom surface of the mounting plate 71 by bolts. When the mounting plate 71 is at its highest position, the distance between the bottom end of the cutter 74 and the surface of the material plate 3 is ≤1mm, ensuring that the material can be quickly contacted during cutting.

[0028] Please see the appendix Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 Appendix Figure 5 and attached Figure 6 As shown, a connecting frame 8 is fixed to the side of the cutting frame 4 away from the rotating frame 1 by bolts. The connecting frame 8 is provided with a linkage unit 9 that cooperates with the end of the material plate 3. The rotating seat 91 of the linkage unit 9 is installed on the connecting frame 8 through the cutting length adjustment unit 13. The cutting length adjustment unit 13 includes a fixed shaft 131 provided at the end of the rotating seat 91. The end of the fixed shaft 131 passes through the moving groove 132 reserved on the connecting frame 8 and is threaded with a fixing bolt 133.

[0029] A baffle 92 is rotatably connected to the end of the rotating seat 91 via a pin. The baffle 92 is inclined at 45°, with its bottom end close to the end of the material plate 3 and its upper part away from the material plate 3. A top rod 93 is connected to one side of the top of the baffle 92 via a pin. The top rod 93 is laterally slidably mounted on one side of the connecting frame 8 via a linear bearing. The end of the top rod 93 close to the cutting frame 4 is slidably connected to the side wall of the pad 12 via a slider. A telescopic spring 94 (a cylindrical helical telescopic spring is selected to ensure that the pad can be pulled back to its original position) is connected between the side wall of the connecting frame 8 and the side wall of the pad 12 via a hook.

[0030] A rotating column 10 is bolted between the connecting frame 8 and the rotating frame 1. A central column 101 is welded to the upper part of the rotating column 10. The central column 101 is rotatably connected to the inner wall of the rotating cylinder 11 through a rolling bearing. A spring 102 (a torsion spring is selected to ensure that the rotating cylinder can automatically return to its original position after rotation) is provided around the lower side of the bottom of the rotating cylinder 11. The bottom end of the spring 102 is welded to the top of the rotating column 10. The top end of the rotating cylinder 11 is welded to the bottom surface of the pad 12 to ensure that the pad rotates synchronously when the rotating cylinder rotates.

[0031] A slide table 14 (a steel plate with a polytetrafluoroethylene wear-resistant layer on the surface) is welded and fixed on the side of the cutting table 5 near the connecting frame 8. The slide table 14 is located directly below the material plate 3 to be cut, and the bottom of the slide table 14 is flush with the collection station of the material plate 3 (such as a collection frame or conveyor roller) to realize the automatic collection of the cut material plate.

[0032] In specific implementation of this utility model: according to the preset length of the material plate 3 to be cut, loosen the fixing bolt 133 of the cutting length adjustment unit 13, push the rotating seat 91 along the moving groove 132, measure the distance between the rotating seat 91 and the cutter 74 with a tape measure, and after reaching the preset length, tighten the fixing bolt 133 to complete the cutting length adjustment.

[0033] The material plate 3 is placed on the transmission roller 2, which drives the material plate 3 to be conveyed towards the cutting frame 4. When the end of the material plate 3 contacts the baffle 92, it pushes the baffle 92 to rotate around the rotating seat 91. The baffle 92 drives the push rod 93 to move laterally. The push rod 93 pushes the pad 12 to rotate around the central column 101 until the pad 12 moves between the stamping column 6 and the cutting unit 7. At this time, the material plate 3 stops conveying (the transmission roller can be paused by a limit switch, or the positioning can be achieved by the friction between the material plate and the baffle). The external cylinder drives the stamping column 6 to move downward. The stamping column 6 fits against the mounting plate 71 and drives it to descend along the slide 72. The compression spring 73 is compressed, and the cutter 74 contacts the material plate 3 and completes the cutting.

[0034] After cutting, the cylinder drives the stamping column 6 to reset upwards, the compression spring 73 rebounds, pushing the mounting plate 71 and the cutter 74 to the initial position. At the same time, the transmission roller 2 resumes conveying, and the cut material plate 3 continues to move towards the connecting frame 8. The end disengages from the baffle 92, the telescopic spring 94 pulls the pad 12 to reset, and the rotating drum 11 drives the pad 12 to rotate to the initial position outside the cutting frame 4 under the action of the return spring 102. The cut material plate 3 slides down the slide table 14 to the collection station, and the subsequent material plates 3 repeat the above process to achieve continuous cutting.

[0035] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
