[0002] Stainless steel pipe is a hollow, long, round steel bar widely used in industrial pipelines and mechanical components in the petroleum, chemical, medical, food, light industry, and instrumentation industries. Furthermore, its light weight, while maintaining the same bending and torsional strength, makes it widely used in the manufacture of mechanical parts and engineering structures. It is also commonly used in furniture and kitchenware. When bending stainless steel pipe, a stainless steel pipe bending device is required.

[0003] However, research has shown that the existing stainless steel tube bending device still has the following defects:

[0004] The clamp on the existing Miaojia DW32 digital display pipe bender is connected to the bending machine body through a pin. When placing the steel pipe between the clamp and the semicircular plate, the clamp needs to be removed first. After the steel pipe is placed, the clamp is installed so that the steel pipe is located between the clamp and the semicircular plate. After bending the steel pipe, the clamp still needs to be removed from the bending machine body before the steel pipe can be removed. The steps of removing the clamp each time are relatively cumbersome, and the removed clamp and pin need to be held by hand or placed elsewhere, which is relatively inconvenient. Therefore, it is necessary to optimize a stainless steel pipe bending device through technological innovation and design optimization. Utility Model Content

[0005] The clamp on the existing Miaojia DW32 digital display pipe bending machine is connected to the bending machine body through a pin. When placing the steel pipe between the clamp and the semicircular plate, the clamp needs to be removed first. After the steel pipe is placed, the clamp can be installed so that the steel pipe is located between the clamp and the semicircular plate.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the present invention to clearly and completely describe the technical solutions in the present invention. In addition, the forms of the various structures described in the following embodiments are merely examples. The instrument placement rack involved in the present invention is not limited to the various structures described in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0028] This embodiment introduces the specific structure of a stainless steel tube bending device. Figures 1-4 As shown, a stainless steel tube bending device comprises:

[0029] The bending machine body 1 has a semi-circular disc 2 installed on the top of the bending machine body 1;

[0030] Clamping block 3, which is located on one side of the semicircular plate and is used to cooperate with the semicircular disc 2 to clamp the steel pipe;

[0031] The fixed block 4 is fixed to one side of the top of the bending machine body 1. A sliding groove 11 is provided on the top of the fixed block 4. A moving mechanism capable of moving the clamping block 3 is provided in the sliding groove 11.

[0032] The reset mechanism is located inside the sliding groove 11 and is used to reset the clamping block 3.

[0033] The clamping block 3 on the bending machine body 1 is connected to the bending machine body 1 through a pin. When placing the steel pipe between the clamping block 3 and the semicircular plate, the clamp needs to be removed first. After the steel pipe is placed, the clamp is installed so that the steel pipe is located between the clamping block 3 and the semicircular plate. After bending the steel pipe, the clamp still needs to be removed from the bending machine body 1 before the steel pipe can be removed. The steps of removing the clamping block 3 each time are relatively cumbersome, and the removed clamping block 3 and pin need to be held by hand or placed elsewhere, which is relatively inconvenient.

[0034] The moving mechanism includes a sliding block 12 that slides in a sliding groove 11. A rotating rod 9 is provided on one side of the sliding block 12. The end of the rotating rod 9 away from the sliding block 12 passes through the fixed block 4. The rotating rod 9 can rotate and slide on the sliding block 12. The sliding block 12 can be pulled to move by the rotating rod 9, and the sliding block 12 will drive the clamping block 3 to move.

[0035] A fixed post 13 is fixed to the top of the sliding block 12. The fixed post 13 passes through the clamping block 3, and the clamping block 3 can rotate on the fixed post 13. A baffle 5 is fixed to the top of the fixed post 13, and the clamping block 3 rotates slightly as the steel pipe bends, facilitating a close fit with the steel pipe. A fixed plate 6 is provided within the sliding groove 11, and a notch 18 is provided on the fixed plate 6. A protrusion 14 is fixed to the rotating rod 9. The rotating rod 9 and the protrusion 14 can pass through the notch 18, ensuring that the protrusion 14 and the notch 18 are aligned. By pushing the rotating rod 9, the protrusion 14 passes through the notch 18. When the rotating rod 9 drives the sliding block 12 to move close to the rotating disk, the rotating rod 9 is rotated. At this time, the protrusion 14 on the rotating rod 9 is misaligned with the notch 18, causing the fixed plate 6 to block the protrusion 14 and prevent the clamping block 3 from moving. The rotating rod 9 passes through the fixed block 4 and is fixed to a rotating plate 8 at one end. The rotating plate 8 is provided with anti-slip grooves to facilitate the rotation and pulling of the rotating rod 9 through the rotating plate 8. An arc-shaped groove 15 is provided on the sliding block 12, and a sliding rod 16 slides in the arc-shaped groove 15. A connecting rod 17 is fixed on the rotating rod 9, and the connecting rod 17 is fixedly connected to the sliding rod 16 to facilitate limiting the rotation angle of the rotating rod 9, so that the protrusion 14 on the rotating rod 9 can be more accurately aligned with the notch 18 on the fixed plate 6. By cooperating with the protrusion 14 and the notch 18 on the fixed plate 6, the clamping block 3 can be limited without removing the clamping block 3 every time.

[0036] When the steel pipe needs to be removed, the rotating rod 9 needs to be rotated and then pulled, so that the rotating rod 9 drives the sliding block 12 and the clamping block 3 to move.

[0037] The reset mechanism includes a movable plate 10 disposed inside a rectangular groove, a rotating rod 9 passing through the movable plate 10, and a rotational connection between the rotating rod 9 and the movable plate 10. A spring 19 is provided between the fixed plate 6 and the movable plate 10. The rotating rod 9 can drive the movable plate 10 to slide in the sliding groove 11, and the movable plate 10 will squeeze the spring 19. When the fixed plate 6 is no longer blocking the protrusion 14, under the action of the spring 19, the movable plate 10 will drive the sliding block 12 and the clamping block 3 to move by themselves through the rotating rod 9. A guide column 7 is provided on the side of the fixed plate 6 away from the sliding block 12. The two ends of the guide column 7 are respectively fixed to the fixed plate 6 and the fixed block 4. The guide column 7 passes through the movable plate 10, and the movable plate 10 can slide on the guide column 7. The spring 19 is sleeved on the outside of the guide column 7 to improve the stability of the movable plate 10 during movement and prevent the spring 19 from falling off between the movable plate 10 and the fixed plate 6.

[0038] Among them, the model of the bending machine body 1 is Miaojia DW32 digital display pipe bending machine.

[0039] When the staff needs to bend the steel pipe, the steel pipe is placed between the clamping block 3 and the semicircular plate, ensuring that the protrusion 14 and the notch 18 are in the same direction. By pushing the rotating rod 9, the protrusion 14 passes through the notch 18, and the moving plate 10 squeezes the spring 19. The rotating rod 9 drives the sliding block 12 to move close to the rotating disk and clamp the steel pipe. The rotating rod 9 is rotated. At this time, the protrusion 14 on the rotating rod 9 is misaligned with the notch 18, so that the fixed plate 6 blocks the protrusion 14 to prevent the clamping block 3 from moving. The bending machine body 1 is opened, and the bending machine body 1 drives the semicircular plate to bend the steel pipe. After the bending is completed, the bending machine body 1 is closed and the rotating rod 9 is rotated in the opposite direction. When the fixed plate 6 no longer blocks the protrusion 14, under the action of the spring 19, the moving plate 10 will drive the sliding block 12 and the clamping block 3 to move by themselves through the rotating rod 9, making it easy to remove the steel pipe.

[0040] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all possible embodiments. However, any obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
