Description

Technical Field

[0001] This utility model relates to the field of steel pipe processing technology, and more specifically, to a bending device for irregularly shaped stainless steel pipes. Background Technology

[0002] Stainless steel shaped pipes are a general term for steel pipes with cross-sectional shapes other than round pipes, including welded shaped pipes and seamless shaped pipes. Due to the material, stainless steel shaped pipes are generally made of 304 or higher grade, while 200 and 201 grades have higher hardness and are more difficult to form.

[0003] Existing technologies disclose some patent documents for steel pipe bending devices. Chinese patent application number CN202321792987.6 discloses a steel pipe bending device that can be easily fixed, including a workbench, a fixing plate, and a bending table. The top of the workbench is provided with an L-shaped bracket, and the L-shaped bracket is provided with a first cylinder. The first cylinder is connected to a bending component. The fixing plate is provided on both sides of the top of the workbench. The opposite side walls of the fixing plate are provided with multiple fixing grooves. The fixing grooves are provided with support rods. The support rods are provided with multiple first springs. The first springs are arranged around the outer wall of the support rods. The first springs are provided with first arc-shaped plates. The bending table is provided between the fixing plates. The bending table is provided with a groove, and the groove is provided with multiple bending grooves laterally.

[0004] In the aforementioned patent, the bending groove is not easy to replace, which makes it difficult to bend the steel pipe into different states, resulting in poor ease of use. Therefore, we propose a bending device for irregularly shaped stainless steel pipes. Utility Model Content

[0005] Technical problems to be solved

[0006] To address the problems existing in the prior art, the purpose of this utility model is to provide a bending device for irregularly shaped stainless steel pipes. This utility model uses the rotation of a bidirectional screw to cause two screw nuts to move simultaneously inward or outward. When the bidirectional screw reverses, the two screw nuts move outward. The movement of the screw nuts drives the slide to move, and the movement of the slide drives the clamping plate to move. When the two clamping plates no longer hold the bending groove, the bending groove can be replaced. By replacing different bending grooves, it is convenient to bend the steel pipe to different degrees.

[0022] (1) When the bending groove needs to be replaced, the output end of the servo motor is started to rotate. The rotation of the output end of the servo motor drives the transmission wheel to drive. The transmission wheel and the transmission belt drive the bidirectional screw to rotate. The rotation of the bidirectional screw causes the two screw nuts to move inward or outward at the same time. When the bidirectional screw reverses, the two screw nuts move outward. The movement of the screw nuts drives the slide to move. The movement of the slide drives the clamping plate to move. When the two clamping plates no longer clamp the bending groove, the bending groove can be replaced. By replacing different bending grooves, it is convenient to bend the steel pipe to different degrees.

The steel pipe is clamped and fixed by the movement of the positioning plate. After the steel pipe is fixed, the extension ends of the second cylinders are activated to extend, and the bending part is pushed to move downward by the extension of the extension ends of the second cylinders. The steel pipe is bent by the movement of the bending part. Attached Figure Description

[0033] Workbench 1;

[0034] Bending groove 14 is provided on worktable 1;

[0035] Mounting bracket 18 is fixedly connected to workbench 1. A second cylinder 19 is mounted on mounting bracket 18. The extended end of the second cylinder 19 moves through mounting bracket 18, and a bending member 20 is fixedly connected to the extended end of the second cylinder 19.

[0036] In this embodiment, the mounting bracket 18 is for the convenience of installing the second cylinder 19. When the second cylinder 19 is activated, the extended end extends, which pushes the bending member 20 downward. The movement of the bending member 20, in conjunction with the bending groove 14, bends the steel pipe. In this invention, the rotation of the bidirectional lead screw 5 causes the two lead nuts 6 to move inward or outward simultaneously. When the bidirectional lead screw 5 reverses, the two lead nuts 6 move outward. The movement of the lead nuts 6 drives the slide 7 to move, and the movement of the slide 7 drives the clamping plate 9 to move. When the two clamping plates 9 no longer clamp the bending groove 14, the bending groove 14 can be replaced. By replacing different bending grooves 14, it is convenient to bend the steel pipe to different degrees.

[0037] Specifically, the clamping mechanism includes a power component and a clamping component, both of which are mounted on the worktable 1 and are connected to each other.

[0039] Specifically, the clamping assembly includes a receiving groove 3, a bidirectional lead screw 5, a lead screw 6, a slide block 7, and a clamping plate 9. The receiving groove 3 is opened on the worktable 1. The bidirectional lead screw 5 is rotatably connected to the receiving groove 3. There are two lead screws 6, two slide blocks 7, and two clamping plates 9. The two lead screws 6 are threaded to the surface of the bidirectional lead screw 5. The two slide blocks 7 are respectively fixedly connected to the surface of the two lead screws 6, and the two slide blocks 7 are slidably engaged with the receiving groove 3. The two clamping plates 9 are respectively fixedly connected to the two slide blocks 7.

[0040] In this embodiment, the receiving groove 3 is provided to facilitate the rotational connection of the bidirectional lead screw 5. The receiving groove 3 is slidably engaged with the slide block 7. The rotation of the bidirectional lead screw 5 causes the two lead nuts 6 to move inward or outward simultaneously. When the bidirectional lead screw 5 reverses, the two lead nuts 6 move outward. The movement of the lead nuts 6 drives the slide block 7 to move, and the movement of the slide block 7 drives the clamping plate 9 to move. When the two clamping plates 9 no longer clamp the bending groove 14, the bending groove 14 can be replaced.

[0041] Specifically, the power assembly includes a mounting base 10, a servo motor 11, transmission wheels 12, and a transmission belt 13. The mounting base 10 is fixedly connected to the bottom of the worktable 1. The servo motor 11 is mounted on the side of the mounting base 10. There are two transmission wheels 12, which are respectively fixedly connected to the output end of the servo motor 11 and the surface of the bidirectional lead screw 5. The transmission belt 13 is sleeved on the surface of the two transmission wheels 12 and is connected to the two transmission wheels 12 in a transmission connection.

[0042] In this embodiment, the mounting base 10 is for the convenience of installing the servo motor 11. The output end of the servo motor 11 is started to rotate, and the rotation of the output end of the servo motor 11 drives the transmission wheel 12 to drive, and the transmission wheel 12 and the transmission belt 13 drive the bidirectional lead screw 5 to rotate.

[0043] Specifically, sliding grooves 4 are provided on both the front and rear sides of the receiving groove 3, and sliders 8 are fixedly connected to both the front and rear sides of the two sliding blocks 7. The four sliders 8 slide in cooperation with the two sliding grooves 4.

[0044] In this embodiment, the groove 4 is provided to facilitate sliding engagement with the slider 8. The sliding engagement between the groove 4 and the slider 8 facilitates the stable movement of the slide block 7.

[0045] Specifically, four support plates 15 are fixedly connected to the workbench 1, and a first cylinder 16 is installed on each of the four support plates 15. The extended ends of the four first cylinders 16 move through the four support plates 15, and a positioning plate 17 is fixedly connected to the extended ends of two of the first cylinders 16.

[0046] In this embodiment, the support plate 15 is for the purpose of facilitating the installation of the first cylinder 16. The extension ends of the four first cylinders 16 are activated to extend, and the extension ends of the first cylinders 16 push the positioning plate 17 to move inward. The movement of the positioning plate 17 clamps and fixes the steel pipe.

[0047] Specifically, each of the four corners of the bottom of the workbench 1 is fixedly connected with a support leg 2.

[0048] In this embodiment, the workbench 1 is fixedly connected to four corners at the bottom of each of the four corners, and the workbench 1 is supported by the support legs 2.

[0049] Working principle: When the bending groove 14 needs to be replaced, the output end of the servo motor 11 is started to rotate. The rotation of the output end of the servo motor 11 drives the transmission wheel 12 to drive. The transmission wheel 12 and the transmission belt 13 drive the bidirectional lead screw 5 to rotate. The rotation of the bidirectional lead screw 5 causes the two lead nuts 6 to move inward or outward at the same time. When the bidirectional lead screw 5 reverses, the two lead nuts 6 move outward. The movement of the lead nuts 6 drives the slide 7 to move. The movement of the slide 7 drives the clamping plate 9 to move. When the two clamping plates 9 no longer clamp the bending groove 14, the bending groove 14 can be replaced. By replacing different bending grooves 14, it is convenient to bend the steel pipe to different degrees.
