Description

Technical Field

[0001] This utility model relates to the field of rectangular tube processing technology, specifically to an arc-shaped punching device for rectangular tube processing. Background Technology

[0002] The rectangular tube processing arc punching equipment is used for arc processing and punching on rectangular pipes or fittings.

[0003] Traditional rectangular tube arc punching equipment required manual feeding, which posed a high risk of operation and resulted in low processing efficiency. Summary of the Invention

[0004] To address the problems in the existing technology, this utility model provides an arc-shaped punching device for rectangular tube processing, which uses a mechanical clamping method for feeding, reducing the risk during operation and increasing processing efficiency.

[0005] The technical solution adopted by this utility model to solve its technical problem is an arc-mouth punching device for rectangular tube processing, including a fixed plate, a first servo electric cylinder, an arc-mouth cutting tool, a second servo electric cylinder, an upper mold and a lower mold. The top end of the fixed plate is equipped with a first vertical plate through a first vertical plate. The top of the first vertical plate is connected to a first top plate. The bottom of the first top plate is equipped with a second servo electric cylinder through a fixed seat. The power output end of the second servo electric cylinder is connected to the upper mold. The top of the fixed plate is connected to the lower mold through a support plate near the inner side of the first vertical plate.

[0006] An extension plate is connected to one end of the fixed plate near the bottom. A servo motor is mounted on the top end of the extension plate via a fixed seat. A guide rail is mounted on the top of the extension plate near the center. A lead screw is connected to the power output end of the servo motor. A lead block is sleeved around the lead screw. The bottom end of the lead block is located inside the guide rail. A clamping mechanism is connected to the top of the lead block. The clamping mechanism consists of an L-shaped plate, a clamping plate, a mounting frame, and a third servo electric cylinder. A mounting frame is connected to the upper side of the end of the L-shaped plate. The third servo electric cylinder is mounted on the top of the mounting frame via bolts. The clamping plate is connected to the power output end of the third servo electric cylinder.

[0007] By adopting the above technical solution, the rectangular tube to be punched is placed between the inner wall of the L-shaped plate and the clamping plate. When the third servo electric cylinder works, it drives the clamping plate to move horizontally and clamp the rectangular tube. When the servo motor works, it drives the lead screw to rotate, thereby causing the lead block to move horizontally along the guide rail, thereby driving the clamping mechanism to move, and thus feeding the rectangular tube clamped by the clamping mechanism. This equipment uses a mechanical clamping method for feeding, which reduces the danger during operation and has high processing efficiency.

[0008] Specifically, a first servo electric cylinder is installed on one side of the top of the fixed plate via a mounting base. The power output end of the first servo electric cylinder is connected to a disc-shaped displacement block. A disc-shaped connecting block is installed on one side of the arc-shaped cutting tool. The disc-shaped displacement block and the disc-shaped connecting block are locked together by connecting bolts.

[0009] By adopting the above technical solution, the disc-shaped connecting block and the disc-shaped displacement block can be connected by connecting bolts, and the arc-shaped cutting tool can be easily disassembled by loosening the connecting bolts.

[0010] Specifically, both the upper and lower molds have a bevel at one end that corresponds to the arc-shaped cutting tool.

[0011] Specifically, a second vertical plate is provided at one end of the top of the extension plate, and a bearing is provided at one end of the second vertical plate, with the end of the lead screw located inside the bearing.

[0012] Specifically, a second top plate is welded to the top of the L-shaped plate, and a guide groove is provided through the top of the second top plate, with the top of the clamping plate located inside the guide groove.

[0013] By adopting the above technical solution, the stability of the clamping plate during horizontal movement can be effectively improved by using the guide groove to limit and guide the top of the clamping plate.

[0014] Specifically, both the fixed plate and the extension plate are equipped with foot pads at their bottoms.

[0015] The beneficial effects of this utility model are:

[0016] The present invention discloses an arc-cutting device for processing rectangular tubes. The rectangular tube to be cut is placed between the inner wall of the L-shaped plate and the clamping plate. When the third servo electric cylinder works, it drives the clamping plate to move horizontally to clamp the rectangular tube. When the servo motor works, it drives the lead screw to rotate, so that the clamping mechanism moves horizontally, thereby feeding the rectangular tube clamped by the clamping mechanism. This device uses a mechanical clamping method for feeding, which reduces the danger during operation and has high processing efficiency. Attached Figure Description

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] To enable this equipment to use a mechanical clamping method for feeding, reducing operational risks and improving processing efficiency, such as... Figure 1-4 As shown, the arc-shaped punching equipment for rectangular tube processing according to this utility model includes a fixed plate 1, a first servo electric cylinder 2, an arc-shaped cutting tool 4, a second servo electric cylinder 9, an upper mold 10, and a lower mold 12. The top end of the fixed plate 1 is mounted with a first vertical plate 7 via a first vertical plate 7. The top of the first vertical plate 7 is connected to a first top plate 8. The bottom of the first top plate 8 is provided with a second servo electric cylinder 9 via a fixed seat. The power output end of the second servo electric cylinder 9 is connected to the upper mold 10. The top of the fixed plate 1 is connected to the lower mold 12 via a support plate 11 near the inner side of the first vertical plate 7.

[0025] An extension plate 14 is connected to one end of the fixed plate 1 near the bottom. A servo motor 15 is mounted on the top end of the extension plate 14 via a fixed seat. A guide rail 17 is mounted on the top of the extension plate 14 near the center. A lead screw 18 is connected to the power output end of the servo motor 15. A lead block 19 is sleeved around the lead screw 18. The bottom end of the lead block 19 is located inside the guide rail 17. A clamping mechanism 20 is connected to the top of the lead block 19. The clamping mechanism 20 consists of an L-shaped plate 22, a clamping plate 23, a mounting frame 26, and a third servo electric cylinder 27. The mounting frame 26 is connected to the upper side of the end of the L-shaped plate 22. The third servo electric cylinder 27 is mounted on the top of the mounting frame 26 by bolts. The clamping plate 23 is connected to the power output end of the third servo electric cylinder 27.

[0026] In use, the rectangular tube to be punched is placed between the inner wall of the L-shaped plate 22 and the clamping plate 23. When the third servo electric cylinder 27 works, it drives the clamping plate 23 to move horizontally and clamp the rectangular tube. When the servo motor 15 works, it drives the lead screw 18 to rotate, thereby causing the lead block 19 to move horizontally along the guide rail 17, thereby driving the clamping mechanism 20 to move, and thus feeding the rectangular tube clamped by the clamping mechanism 20. This equipment adopts a mechanical clamping method for feeding, which reduces the danger during operation and has high processing efficiency.

[0027] For example, such as Figure 1-3 As shown, this utility model also includes a first servo electric cylinder 2 installed on one side of the top of the fixed plate 1 via a mounting base. The power output end of the first servo electric cylinder 2 is connected to a disc-shaped displacement block 3. A disc-shaped connecting block 5 is installed on one side of the arc-shaped cutting tool 4. The disc-shaped displacement block 3 and the disc-shaped connecting block 5 are locked together by connecting bolts 6.

[0028] In use, the disc-shaped connecting block 5 and the disc-shaped displacement block 3 can be connected by the connecting bolt 6. The arc-shaped cutting tool 4 can be easily disassembled by loosening the connecting bolt 6.

[0029] For example, such as Figure 1-2 As shown, the present invention also includes that one end of the upper mold 10 and the lower mold 12 are provided with a bevel 13 corresponding to the arc-shaped cutting tool 4.

[0030] In use, the inclined surface 13 facilitates the cooperation with the arc-cutting tool 4, thereby making it convenient to cut an arc at one end of the rectangular tube.

[0031] For example, such as Figure 1 As shown, the present invention also includes a second vertical plate 16 provided at one end of the top of the extension plate 14, a bearing provided at one end of the second vertical plate 16, and the end of the lead screw 18 located inside the bearing.

[0032] During use, the bearing's limiting and guiding effect on the end of the lead screw 18 can effectively improve the stability of the lead screw 18 during rotation.

[0033] For example, such as Figure 4 As shown, the present invention also includes a second top plate 24 welded to the top of the L-shaped plate 22, a guide groove 25 extending through the top of the second top plate 24, and the top of the clamping plate 23 located within the guide groove 25.

[0034] When in use, the guide groove 25 limits and guides the top of the clamping plate 23, which can effectively improve the stability of the clamping plate 23 when moving horizontally.

[0035] For example, such as Figure 1-3As shown, the present invention also includes foot pads 21 at the bottom of both the fixing plate 1 and the extension plate 14.

[0036] When in use, the foot pads 21 can effectively improve the shock absorption effect at the bottom of the device.

[0037] In use, the rectangular tube to be punched is placed between the inner wall of the L-shaped plate 22 and the clamping plate 23. When the third servo electric cylinder 27 works, it drives the clamping plate 23 to move horizontally and clamp the rectangular tube. When the servo motor 15 works, it drives the lead screw 18 to rotate, thereby causing the lead block 19 to move horizontally along the guide rail 17, thereby driving the clamping mechanism 20 to move, and thus allowing the rectangular tube clamped by the clamping mechanism 20 to be loaded. The second servo electric cylinder 9 is used to easily drive the upper mold 10 to press down. The upper mold 10 and the lower mold 12 are used to easily clamp the rectangular tube. This equipment uses a mechanical clamping method for loading, which reduces the danger during operation and has high processing efficiency.

[0038] When the rectangular tube is clamped, the first servo electric cylinder 2 drives the disc-shaped displacement block 3 to move horizontally. When the disc-shaped displacement block 3 moves horizontally, it drives the disc-shaped connecting block 5 and the arc-shaped cutting tool 4 to move horizontally. The arc-shaped cutting tool 4 cooperates with the inclined surface 13 to facilitate the arc-shaped punching operation on the part of the rectangular tube exposed on the inclined surface 13.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
