Description

Technical Field

[0001] This utility model relates to the field of steel pipe processing, specifically a feeding device for steel pipe cutting. Background Technology

[0002] Steel pipes are tubular materials made of steel and can be used to transport fluids, withstand pressure, and manufacture structural components. Due to their high strength, good toughness, and excellent processing performance, they are widely used in industries such as construction, machinery manufacturing, petrochemicals, aerospace, and automobile manufacturing. In actual use, steel pipes need to be cut and processed to adapt to different environments and functions.

[0003] Currently, most steel pipe feeding is still done manually, requiring people to place each steel pipe onto the processing table and push it for cutting. However, manual feeding is not only slow, affecting the efficiency of cutting, but also carries certain risks during the manual feeding and cutting process. Therefore, a steel pipe cutting feeding device is proposed to solve the above problems. Utility Model Content

It solves the problem that most existing steel pipe feeding methods are still manual, requiring manual placement of each steel pipe on the processing table and pushing it for cutting. Manual feeding is not only slow and affects cutting efficiency, but also involves certain risks during the manual feeding and cutting process.

[0017] Furthermore, the interiors of both the first and second conveyor wheels are arc-shaped, and both are wider on the outside and narrower on the inside. Both the first and second conveyor wheels are equipped with cushioning pads inside.

[0018] The beneficial effect of adopting the above-mentioned further solution is that it adapts the conveyor wheel to the shape of the steel pipe and prevents the steel pipe from sliding relative to the conveyor wheel during conveying, thus affecting the conveying effect.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] In the embodiments, by Figure 1-4A feeding device for cutting steel pipes is provided. This utility model includes a first support frame 1, a placement frame 2 fixedly connected to the top of the first support frame 1, a rotating device 3 inside the first support frame 1, a connecting shaft 4 fixedly connected to the inside of the rotating device 3 and rotatably connected to the inside of the first support frame 1, two transfer frames 5 fixedly connected to the outside of the connecting shaft 4 and symmetrically distributed from left to right, a limiting frame 6 fixedly connected to the outside of the first support frame 1, a second motor 7 fixedly connected to the outside of the limiting frame 6, a first conveying wheel 8 located inside the limiting frame 6 fixedly connected to the outside of the output shaft of the second motor 7, a second support frame 9 arranged on the right side of the first support frame 1, two transmission devices 10 symmetrically distributed from front to back arranged inside the second support frame 9, two second conveying wheels 11 fixedly connected to the outside of each of the two transmission devices 10, and a cutting machine 12 arranged on the outside of the second support frame 9.

[0028] The rotating device 3 includes a first motor 31 fixedly connected to the inside of the first support frame 1. A worm gear 32, which is rotatably connected to the inside of the first support frame 1, is fixedly connected to the outside of the output shaft of the first motor 31. A worm wheel 33, which meshes with the worm gear 32, is fixedly connected to the outside of the connecting shaft 4. The first motor 31 is a DC motor.

[0029] In this embodiment, during actual use, the start of the first motor 31 will drive the worm 32 to rotate, and under the action of the thread, the worm wheel 33 will rotate, thereby causing the connecting shaft 4 inside the worm wheel 33 to rotate tensilely, and then causing the two transfer frames 5 to rotate, so as to collect the steel pipe on the rear side or pour the steel pipe into the limiting frame 6 on the front side.

[0030] The interiors of the two transfer frames 5 are inclined, and the interior of the placement frame 2 has two clearance slots. The two transfer frames 5 are located inside the two clearance slots respectively.

[0031] In this embodiment, during actual use, when the transfer frame 5 rotates backward, the steel pipe will roll onto the transfer frame 5 along the inclined slope. As the transfer frame 5 rotates forward, the steel pipe will roll down into the limiting frame 6 along the inner side of the inclined transfer frame 5. The clearance groove in the placement frame 2 provides space for the transfer frame 5 to rotate back and forth without affecting the placement of the steel pipe.

[0032] The single transmission device 10 includes a third motor 101 fixedly connected to the outside of the second support frame 9. The output shaft of the third motor 101 is fixedly connected to the outside of a first transmission wheel 102. The outside of the second support frame 9 is rotatably connected to a fixed shaft 103. The outside of the fixed shaft 103 is fixedly connected to a second transmission wheel 104 connected to the first transmission wheel 102 via a transmission belt. The output shaft of the third motor 101 and the outside of the fixed shaft 103 are respectively fixedly connected to two second conveying wheels 11.

[0033] In this embodiment, during actual use, the start of the third motor 101 will drive the first transmission wheel 102 to rotate, and under the action of the transmission belt, the second transmission wheel 104 will rotate, and the fixed shaft 103 inside the second transmission wheel 104 will rotate, while the two second conveyor wheels 11 above will rotate.

[0034] The first conveyor wheel 8 and the second conveyor wheel 11 are both arc-shaped inside, and both are wider on the outside and narrower on the inside. Both the first conveyor wheel 8 and the second conveyor wheel 11 are equipped with a buffer pad inside.

[0035] In this embodiment, during actual use, the steel pipe is conveyed to the right by the rotation of the first conveying wheel 8 driven by the second motor 7 from the limiting frame 6, and the steel pipe passes between the two second conveying wheels 11 to further move the steel pipe to the right.

[0036] Among them, the baffle of the limiting frame 6 is set with the front higher than the back, and the inner right wall of the limiting frame 6 is provided with a clearance hole. The axis of symmetry of the two second conveying wheels 11 is on the same horizontal plane as the central axis of the first conveying wheel 8.

[0037] In this embodiment, during actual use, the clearance hole provides space for the steel pipe to pass through, and the conveying wheels on the same horizontal plane ensure the direction and stability of the steel pipe conveying. When the steel pipe rolls from the transfer frame 5 into the limiting frame 6, the high setting of the limiting frame 6 can prevent the steel pipe from falling.

[0038] Working principle:

[0039] When cutting steel pipes, a batch of steel pipes can first be placed flat on the placement frame 2. The placement frame 2 is slightly tilted forward, and the steel pipes cannot move due to the obstruction of the edge of the transfer frame 5. The first motor 31 is started to rotate the transfer frame 5, and some of the steel pipes on the placement frame 2 roll down into the transfer frame 5. As the transfer frame 5 returns to its original position, some steel pipes will roll into the transfer frame 5. At this time, the transfer frame 5 is rotated forward, and the steel pipes will roll down into the limiting frame 6. The transfer of the transfer frame 5 can ensure the number of steel pipes passing through each time and prevent a large number of steel pipes from falling into the limiting frame 6. The second motor 7 drives the rotation of the first conveying wheel 8 to transport the steel pipes to the right and make the steel pipes extend into the four second conveying wheels 11 for further transport. The steel pipes moving to the right can pass through the holes of the second support frame 9 and extend to the bottom of the cutting machine 12 for cutting.
