Description

Technical Field

[0001] The utility model relates to an efficient automatic steel pipe cutting device, belonging to the technical field of cutting devices. Background Art

[0002] A steel pipe is a steel product with a hollow cross-section, and its length is much greater than the diameter or circumference. It is divided into circular, square, rectangular and special-shaped steel pipes according to the cross-sectional shape; it is divided into carbon structural steel pipes, low-alloy structural steel pipes, alloy steel pipes and composite steel pipes according to the material; it is divided into steel pipes for conveying pipelines, engineering structures, thermal equipment, petrochemical industries, mechanical manufacturing, geological drilling, high-pressure equipment, etc. according to the use; it is divided into seamless steel pipes and welded steel pipes according to the production process, among which seamless steel pipes are further divided into hot-rolled and cold-rolled (drawn) types, and welded steel pipes are further divided into straight-seam welded steel pipes and spiral-seam welded steel pipes.

[0003] The Chinese published patent (publication number: CN 205032795 U) discloses an automatic steel pipe cutting device, including a first cylinder, a second cylinder, a third cylinder and a feeding trough. The first cylinder is fixedly connected to a baffle, the second cylinder is fixedly connected to an upper pressing plate, and a lower pressing box is fixedly provided corresponding to the bottom of the upper pressing plate. Grooves are correspondingly provided at the top of the lower pressing box and the bottom end of the upper pressing plate. A distance sensor is fixedly provided at the side of the top end of the lower pressing box. The third cylinder is fixedly connected to a cutting grinder. The utility model has a simple structure, convenient operation and strong practicability; through the first cylinder, the second cylinder, the third cylinder and the distance sensor are all signal-connected to a control terminal, and the control terminal controls each part to work to automatically cut the steel pipe, with strong cutting precision and improved cutting quality; through the grooves correspondingly provided at the top of the lower pressing box and the bottom end of the upper pressing plate, and multiple grooves are provided to place multiple steel pipes and then fix and cut them, and multiple steel pipes can be cut simultaneously, effectively improving the cutting efficiency;

[0004] The above device mainly relies on the feeding trough and the downward pressure of the cylinder to fix the steel pipe. However, there are many types and sizes of steel pipes. When the size of the steel pipe changes, since the inner size of the feeding trough is relatively fixed and cannot be adjusted synchronously with the size of the steel pipe, it may cause that when the cylinder presses down to fix the steel pipe, the steel pipe cannot be stably placed inside the feeding trough, so that the steel pipe may be offset as a whole due to the centrifugal force of the rotating blade during cutting and move out of the cutting range of the blade, thus affecting the normal cutting work.

[0005] Therefore, an efficient automatic steel pipe cutting device is proposed. Content of the Utility Model

[0006] In view of this, the utility model provides an efficient automatic steel pipe cutting device to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial option.

[0007] The technical solution of the utility model is realized as follows: An efficient automatic steel pipe cutting device, including a support frame, a first mounting frame is fixedly installed at the top of the support frame, a second mounting frame is fixedly installed at the top of the first mounting frame, a third mounting frame is fixedly installed at the top of the second mounting frame, cylinders are fixedly installed on both the front and rear sides of the top of the third mounting frame, and cutting machines are fixedly installed at the bottoms of the cylinders;

[0008] A fixing mechanism is arranged on the surface of the support frame. The fixing mechanism includes a motor and a lead screw. The motor is fixedly installed at the bottom of the support frame. The two lead screws are respectively arranged on the left and right sides of the top of the first mounting frame. Nuts are threadedly connected to the surfaces of the two lead screws.

Driven gears are movably connected to both the left and right sides of the top of the support frame. The surface of the driving gear meshes with the surface of the toothed ring. The surfaces of the two driven gears both mesh with the surface of the toothed ring. The tops of the two driven gears are fixedly connected to the bottoms of the two lead screws.

[0010] Further preferably, sliding grooves are respectively opened on both the left and right sides of the top of the second mounting frame. The two mounting rods respectively penetrate through the inner cavities of the two sliding grooves and extend to the top of the second mounting frame.

[0011] Further preferably, limiting rods are fixedly installed on both the left and right sides of the top of the first mounting frame. The inner surfaces of the two nuts are slidably connected to the surfaces of the two limiting rods.

[0012] Further preferably, moving grooves are respectively opened on both the left and right sides of the top of the first mounting frame. The bottoms of the two moving blocks are slidably connected to the inner cavities of the two moving grooves.

[0016] Since the embodiment of the present utility model adopts the above technical solutions, it has the following advantages:

[0017] 1. By setting the fixing mechanism in the present utility model, the motor outputs power, and through the cooperation of the driving gear, the toothed ring and the driven gear, the lead screw rotates. At this time, the screw block and the fixing block move downward, and the connecting rod flips. At this time, the moving block is pushed inward by the connecting rod, and drives the mounting rod and the fixing plate to move inward, and completes the fixing work of the steel pipe. Since the mounting rod and the fixing plate have adjustable characteristics, it is convenient to fix steel pipes of different sizes, improving the fixable range, and effectively avoiding the situation that due to the change of the size of the steel pipe, the inner diameter of the fixture cannot be adjusted, which affects the normal cutting work of the steel pipe.

[0018] 2.

By setting the limiting rod, the movement of the screw block can be limited to prevent the screw block from shifting during movement, thus affecting the limiting work of the steel pipe. By setting the moving groove, the movement of the moving block can be limited to prevent the moving block from changing direction during movement, thus causing the problem that the steel pipe cannot be fixed. By setting the annular groove and the slider, the toothed ring can be supported and limited, effectively preventing the toothed ring from deviating in direction during rotation, thus affecting the transmission of subsequent components and resulting in the situation that the steel pipe cannot be fixed. By setting the cutting groove, it can be avoided that when the cutting machine cuts the steel pipe downward, due to the obstruction of the second mounting frame, the normal cutting work is affected. By setting the anchor bolts, the overall equipment can be stabilized, ensuring the stability of the overall position of the equipment during the cutting of the steel pipe.

Therefore, the drawings and the description are considered to be exemplary in nature rather than restrictive.

[0029] The embodiments of the present utility model will be described in detail below with reference to the drawings.

[0030] Embodiment 1

[0031] As Figure 1-6 shown, the embodiment of the present utility model provides an efficient automatic steel pipe cutting device, including a support frame 1, a first mounting bracket 3 is fixedly installed on the top of the support frame 1, a second mounting bracket 4 is fixedly installed on the top of the first mounting bracket 3, a third mounting bracket 5 is fixedly installed on the top of the second mounting bracket 4, cylinders 6 are fixedly installed on both the front and rear sides of the top of the third mounting bracket 5, and cutting machines 7 are fixedly installed at the bottoms of the cylinders 6;

[0032] A fixing mechanism 2 is arranged on the surface of the support frame 1. The fixing mechanism 2 includes a motor 201 and a lead screw 205. The motor 201 is fixedly installed at the bottom of the support frame 1. The two lead screws 205 are arranged on the left and right sides of the top of the first mounting frame 3. Threaded blocks 206 are threadedly connected to the surfaces of the two lead screws 205. Fixed blocks 207 are fixedly installed on the inner sides of the two threaded blocks 206. Connecting rods 208 are movably connected to the outer sides of the two fixed blocks 207. The inner sides of the four connecting rods 208 are movably connected to moving blocks 209. Mounting rods 210 are fixedly installed on the tops of the two moving blocks 209. Fixing plates 211 are fixedly installed on the inner sides of the two mounting rods 210. The output end of the motor 201 is fixedly connected to a driving gear 202. A toothed ring 203 is arranged on the top of the support frame 1. The left and right sides of the top of the support frame 1 are movably connected to driven gears 204. The surface of the driving gear 202 meshes with the surface of the toothed ring 203. The surfaces of the two driven gears 204 both mesh with the surface of the toothed ring 203. The tops of the two driven gears 204 are fixedly connected to the bottoms of the two lead screws 205.

[0033] By arranging the fixing mechanism 2, the motor 201 outputs power, and through the cooperation of the driving gear 202, the toothed ring 203 and the driven gears 204, the lead screw 205 rotates. At this time, the threaded block 206 and the fixed block 207 move downward, and the connecting rod 208 is flipped. At this time, the moving block 209 is pushed inward by the connecting rod 208, and the mounting rod 210 and the fixing plate 211 are driven to move inward, and the fixing work of the steel pipe is completed. Since the mounting rod 210 and the fixing plate 211 have adjustable characteristics, it is convenient to fix steel pipes of different sizes, improving the fixable range and effectively avoiding the situation that the inner diameter of the fixture cannot be adjusted due to the change of the size of the steel pipe, which affects the normal cutting work of the steel pipe.

[0034] Embodiment 2

[0035] Such as Figure 2-5As shown, in one embodiment, sliding grooves 212 are formed on both the left and right sides at the top of the second mounting bracket 4. Both mounting rods 210 penetrate through the inner cavities of the two sliding grooves 212 and extend to the top of the second mounting bracket 4. Limiting rods 213 are fixedly installed on both the left and right sides at the top of the first mounting bracket 3. The inner surfaces of the two screw blocks 206 are slidably connected to the surfaces of the two limiting rods 213. Moving grooves 214 are formed on both the left and right sides at the top of the first mounting bracket 3. The bottoms of the two moving blocks 209 are slidably connected to the inner cavities of the two moving grooves 214. An annular groove 215 is formed at the top of the support frame 1. Sliders 216 are fixedly installed at the bottoms of the toothed rings 203. The bottoms of the seven sliders 216 are slidably connected to the inner cavity of the annular groove 215. Cutting grooves 8 are formed on both the front and rear sides at the top of the second mounting bracket 4. The two cutting grooves 8 and the two cutting machines 7 are in the same vertical direction. Bottom plates 9 are fixedly installed on both the left and right sides at the bottom of the support frame 1. Anchor bolts 10 are threadedly connected to the front and rear sides of the tops of the two bottom plates 9.

[0036] By providing the sliding grooves 212, the movement of the mounting rods 210 can be limited to prevent the mounting rods 210 from shifting during movement, thus affecting the fixing of the steel pipe. By providing the limiting rods 213, the movement of the screw blocks 206 can be limited to prevent the screw blocks 206 from shifting during movement, thus affecting the limiting of the steel pipe. By providing the moving grooves 214, the movement of the moving blocks 209 can be limited to prevent the direction of the moving blocks 209 from changing during movement, thus avoiding the problem of being unable to fix the steel pipe. By providing the annular groove 215 and the sliders 216, the toothed rings 203 can be supported and limited, effectively preventing the toothed rings 203 from deviating in direction during rotation, thus affecting the transmission of subsequent components and resulting in the situation of being unable to fix the steel pipe. By providing the cutting grooves 8, it can be avoided that when the cutting machine 7 cuts the steel pipe downward, the normal cutting work is affected due to the obstruction of the second mounting bracket 4. By providing the anchor bolts 10, the overall equipment can be stabilized, ensuring the stability of the overall position of the equipment during the cutting of the steel pipe.

[0037] When the utility model works: First, place the steel pipe inside the fixing plate 211. Then, through the output of the motor 201, the driving gear 202 rotates at this time, and drives the toothed ring 203 to rotate synchronously. As the toothed ring 203 rotates, the driven gear 204 rotates synchronously, and the lead screw 205 rotates along with it. At this time, the screw block 206 moves downward along the surface of the lead screw 205, and synchronously drives the fixing block 207 to move downward. As the fixing block 207 moves, the connecting rod 208 flips, and pushes the moving block 209 to move inward. At this time, the moving block 209 drives the mounting rod 210 and the fixing plate 211 to move inward synchronously, and completes the fixing work of the steel pipe. Then, drive the cutting machine 7 to move downward through the cylinder 6. At this time, the cutting machine 7 enters the working state, and drives the blade inside it to rotate. As the cylinder 6 continuously drives the cutting machine 7 to move downward, and makes the cutting machine 7 contact the surface of the steel pipe, thus completing the cutting work of the steel pipe.

[0038] The above is only the specific implementation manner of the utility model, but the protection scope of the utility model is not limited thereto. Any person skilled in the art in the technical field disclosed by the utility model can easily think of various changes or substitutions within the technical scope disclosed by the utility model, and these should all be covered within the protection scope of the utility model. Therefore, the protection scope of the utility model should be subject to the protection scope of the claimed rights.
