Description

Technical Field

[0001] This utility model relates to the field of steel pipe processing technology, and in particular to a steel pipe cutting device with a protective structure. Background Technology

[0002] Steel pipes are hollow steel materials whose length is much greater than their diameter or circumference. They are used not only for transporting fluids and powdery solids, exchanging heat, and manufacturing mechanical parts and containers, but also as an economical steel material. Using steel pipes to manufacture building structural frames, pillars, and mechanical supports can reduce weight. Steel pipe cutting machines are mechanical devices developed to meet the demands of modern society for steel pipes, cutting them during the processing of steel pipes. Existing cutting devices can smoothly cut away burrs, improving convenience.

[0003] In the existing technology, general steel pipe cutting equipment has a relatively simple structure. During processing, it is easy to clamp and fix the steel pipe. The steel pipe may vibrate and deflect excessively due to the collision with the cutting head, which will affect the processing quality and work efficiency, and may even endanger personal safety. Therefore, its applicability is low. Utility Model Content

[0004] This utility model discloses a steel pipe cutting device with a protective structure, which aims to solve the technical problem that when general steel pipe cutting equipment is used for processing, the clamping and fixing of steel pipes is relatively simple, and the steel pipes may experience excessive vibration and deflection due to collision with the cutting head.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A steel pipe cutting device with a protective structure includes a base. Two symmetrically positioned fixing frames are fixedly connected to the top of the base, and the same clamping assembly is mounted on each fixing frame. A mounting frame is fixedly connected to the top of the base, and the same protective cutting assembly is mounted on both the top of the base and the mounting frame. Two symmetrically positioned support frames are fixedly connected to the top of the base, and the same conveying module is mounted on each support frame. The clamping assembly includes a fixing ring, which is fixedly connected to the inner walls of both fixing frames. A motor is mounted on the top of the fixing ring, and the output end of the motor is connected to a gear via a coupling. A rotating ring is movably connected to the inner wall of the fixing ring, and a gear is fixedly connected to the outer wall of the rotating ring. A gear ring meshes with a gear. The rotating ring has multiple circumferentially spaced arc-shaped grooves, each containing a sliding rod. A fixed ring has multiple circumferentially spaced sliding grooves, each containing a sliding block. Each sliding block is fixedly connected to a corresponding sliding rod. One side of each sliding block is fixedly connected to a mounting component. The inner wall of each mounting component is fixedly connected to multiple circumferentially spaced springs. The ends of multiple springs in the same row furthest from their respective mounting components are fixedly connected to the same fixing component. Each fixing component has multiple equally spaced circular holes, each containing a movably connected thin rod. The outer wall of each thin rod is fixedly connected to a roller.

[0007] The system incorporates a clamping assembly. A motor drives a gear to rotate, which in turn meshes with a rotating gear ring, causing the rotating ring to rotate. An arc-shaped groove forces a sliding rod to slide, causing multiple mounting components to move towards the center and clamp the steel pipe. During the steel pipe transport process, as the components move within the assembly, springs push the fixing components, bringing the rollers into contact with the outer wall of the steel pipe. The rolling action of the rollers reduces wear on the steel pipe during transport. When vibrations occur, the tension and compression of multiple springs dampen the vibrations and increase stability during cutting.

[0008] In a preferred embodiment, the mounting frame has a mounting groove, and a collection chamber is fixedly connected to the mounting groove. The collection chamber has a second circular hole and multiple third circular holes. A connecting pipe is fixedly connected to the second circular hole, and a sliding rod is slidably connected to each of the multiple third circular holes. A collection box is provided below the mounting frame, and a fourth circular hole is provided on the collection box. The end of the connecting pipe away from the collection chamber is fixedly connected to the fourth circular hole. A negative pressure pump is provided on one side of the collection box and is fixedly connected to the collection box. The top of the multiple sliding rods is fixedly connected to the same movable plate, and a cutting machine is fixedly connected to the bottom of the movable plate. Protective baffles are fixedly connected to the outer walls of the opposite sides of the movable plate. A hydraulic rod is provided at the bottom of the mounting frame, and the driving end of the hydraulic rod passes through one of the third circular holes and is fixedly connected to the bottom end of the corresponding sliding rod.

[0009] Equipped with protective cutting components, the moving plate is pulled by a hydraulic rod using a sliding rod, causing the cutting machine to descend and cut the steel pipe. Protective baffles on both sides of the moving plate can block sparks generated during cutting, increasing the safety of the device. At the same time, a negative pressure pump can create negative pressure inside the collection box and collection chamber, collecting the waste residue and exhaust gas generated during cutting into the collection box, preventing pollution to the working environment, reducing manpower consumption during cleaning, and improving the safety and convenience of the device.

[0010] In a preferred embodiment, the conveying module includes two symmetrical mounting frames, each fixedly connected to an adjacent support frame. A second motor is fixedly connected to the top of one support frame. A circular hole five is provided on the mounting frame closest to the second motor, and a threaded rod is movably connected within the circular hole five. Pulleys are fixedly connected to the outer walls of both the threaded rod and the second motor, and the outer walls of the two pulleys are slidably connected to the same belt. Two movable blocks are threadedly connected to the outer wall of the threaded rod. A circular hole six is ​​provided on the inner wall of the other mounting frame, and a limit rod is fixedly connected within the circular hole six. Two movable blocks are slidably connected to the outer wall of the limit rod. Circular holes seven are provided on each of the movable blocks, and the same transmission wheel is movably connected to each of the two opposing circular holes seven.

[0011] By incorporating a conveyor module, a motor drives a threaded rod via a belt, and the two movable blocks move in opposite directions through the bidirectional thread, enabling the conveyor wheels to transport steel pipes of different diameters, thus increasing the convenience and applicability of the device.

[0012] As can be seen from the above, the steel pipe cutting device with protective structure provided by this utility model has the technical effect of stably clamping and damping the steel pipe during processing, avoiding excessive vibration and deflection of the steel pipe, improving processing quality and work efficiency, and enhancing applicability.
