TECHNICAL FIELD

[0001] The utility model relates to steel structure processing technical field, concretely is a round pipe cutting mechanism with clamping structure. BACKGROUND

[0002] Steel structure is the structure of steel material composition, is one of main building structure types. The structure is mainly composed of the steel beam, steel column, steel truss and other components made of section steel and steel plate, and adopts rust removal and rust prevention technology such as silanization, pure manganese phosphating, washing and drying, galvanizing. Welding, bolts or rivets are usually used to connect between each component or part. Because its weight is lighter, and the construction is simple, it is widely used in large factory, venue, super high-rise, bridge and other fields, in industrial production and construction and many other fields, as a kind of commonly used basic material, round pipe is often needed to be cut according to specific design and construction requirements before use.

[0003] The existing cutting mechanism only has cutting function, so clamping and cutting are separate steps, and two people are needed to operate to complete round pipe cutting, which leads to too long cutting operation time, reduces work efficiency, and the existing cutting mechanism is cut by manually moving cutting equipment to align cutting position, or because of the vibration of equipment, the shaking of cutter head or the shaking of manual holding, the cutting position is offset to produce error, which reduces the precision and quality of cutting. SUMMARY

[0004] The utility model discloses a main purpose is to solve the above-mentioned existing cutting efficiency is low and the technical problem of cutting position offset, provide a kind of round pipe cutting mechanism with clamping structure.

[0005] The specific solution of this utility model is as follows: a circular tube cutting mechanism with a clamping structure, including a cutting structure, a mounting plate, a driving mechanism mounted on the top of the mounting plate, a cutter mounted on the bottom of the mounting plate, and a push block mounted on one side of the cutter. A first inclined surface is provided on one side of the push block. A clamping structure is installed below the cutting structure, including a base, a fixing block mounted on the top of the base, a first semi-circular groove on one side of the fixing block, and a first cutting inlet at the top of the fixing block. The first cutting inlet extends downwards along the height direction of the fixing block to the bottom and communicates with the first semi-circular groove. A movable block is slidably mounted on the top of the base and is parallel to the base. On one side of the fixed block, a second semi-circular groove is provided on the side of the movable block. A second cutting inlet is provided at the top of the movable block, extending downwards along the height direction of the movable block to the bottom and communicating with the second semi-circular groove. A second inclined surface is provided on one side of the movable block. When the mounting plate moves downwards, the first inclined surface and the second inclined surface press against each other, causing the movable block to move horizontally toward the fixed block, and the cutter is inserted into the first and second cutting inlets. When the movable block and the fixed block coincide, the first and second semi-circular grooves form a circular structure, and the first and second cutting inlets form a straight line. A spring-loaded structure is provided on one side of the movable block, which is used to automatically return the movable block to its original position when it loses the pressure of the push block.

[0006] According to the above technical solution, the moving block is pushed closer to the fixed block by the pusher to achieve the effect of clamping the steel pipe, while the cutter cuts into the steel pipe through the first and second cutting inlets to complete the cutting work.

[0007] Furthermore, the rebound structure includes a stop block fixed to the top of the base, the stop block being located on one side of the moving block, a slide rod being installed at the end of the moving block away from the second semi-circular groove, the other end of the slide rod passing through the stop block and connected to a limit block, a spring being fitted on the surface of the slide rod, and the spring being fitted between the limit block and the stop block; the bottom end of the push block is provided with a first clearance groove, which is used to ensure that the push block is not blocked by the slide rod when pushing the moving block.

[0008] According to the above technical solution, when the moving block moves closer to the fixed block using a spring, it drives the sliding rod to move to one side, allowing the spring to perform elastic storage. After the push block is raised, the moving block returns to its original position, making it easier to clamp the next steel pipe.

[0009] Furthermore, the top of the fixing block is provided with a second clearance groove, which extends downward along the height direction of the fixing block to the bottom. The second clearance groove is located on one side of the first cutting entrance and communicates with the first cutting entrance. A concave mounting block is installed at the bottom of the mounting plate, and the concave mounting block is located directly above the second clearance groove. The surface of the cutter is provided with several fixing holes. The concave mounting block is detachably connected to the cutter in the groove, and the concave mounting block can be inserted into the second clearance groove.

[0010] According to the above technical solution, a cutter is placed in the groove of the concave mounting block, and then a bolt is passed through the mounting block and then through the fixing hole for fixation, which facilitates disassembly and replacement later.

[0011] Furthermore, the mounting plate is provided with sleeves at the four corners of the bottom end, and guide rods are provided at the four corners of the top end of the base. When the mounting plate moves downward, the sleeves slide onto the guide rods.

[0012] According to the above technical solution, the sleeve slides inside the guide rod when it moves downward, which has a guiding effect and improves the stability during extrusion cutting.

[0013] Furthermore, the bottom end of the cutter has a V-shaped structure, with symmetrical bevels on both sides of the V-shape.

[0014] According to the above technical solution, the V-shaped structure with symmetrical inclined planes on both sides makes it easier to insert into the steel pipe for cutting.

[0015] Furthermore, the drive mechanism is a hydraulic cylinder drive.

[0016] According to the above technical solution, driving the mounting plate to move via a hydraulic rod is more stable and reliable.

[0017] Compared with the prior art, the present invention has the following advantages: 1. The round tube cutting mechanism with clamping structure can accurately position the round tube in the circular structure when the moving block and the fixed block overlap, by cooperating the first semi-circular groove and the first cutting entrance on the fixed block and the second semi-circular groove and the second cutting entrance on the moving block. This keeps the round tube in a fixed and accurate position. At the same time, the moving block can work synchronously with the cutter when it moves, so that clamping and cutting can be carried out simultaneously, saving operation time and greatly improving work efficiency.

[0018] 2. The circular tube cutting mechanism with clamping structure guides the cutter through the first cutting inlet, the second cutting inlet, the sleeve, and the guide rod, which can effectively reduce the vibration and shaking generated during the cutting process, thereby reducing the error of the cutting position and improving the cutting quality and accuracy.

[0019] 3. The round tube cutting mechanism with clamping structure allows for detachable installation of the cutter via a concave mounting block, facilitating later maintenance and replacement and further improving its practicality. Attached Figure Description

[0025] See Figures 1-4 This embodiment is a circular tube cutting mechanism with a clamping structure. The cutting structure includes a mounting plate 1, a driving mechanism mounted on the top of the mounting plate 1 for driving the mounting plate 1 to move vertically up and down, a cutter 2 mounted on the bottom of the mounting plate 1, and a push block 3 parallel to one side of the cutter 2. The push block 3 has a first inclined surface 4 on the side near the cutter 2. A clamping structure is mounted directly below the cutting structure for fixing the steel pipe and providing guidance for the cutter 2 to cut the steel pipe. The clamping structure includes a base 5, a fixing block 6 welded to the top of the base 5, a first semi-circular groove 7 on one side of the fixing block 6, and a first cutting entrance 8 at the top of the fixing block 6. The first cutting entrance 8 extends downward along the height direction of the fixing block 6 to the bottom and communicates with the first semi-circular groove 7. A movable block 9 is slidably mounted on the top of the base 5 and is parallel to one side of the fixing block 6. The movable block 9 is close to the fixing block 6. The fixed block 6 has a second semi-circular groove 10 on one side, and the top of the movable block 9 has a second cutting inlet 11. The second cutting inlet 11 extends downward along the height direction of the movable block 9 to the bottom and communicates with the second semi-circular groove 10. The movable block 9 has a second inclined surface 12 on the side away from the fixed block 6. When the mounting plate 1 moves downward, the first inclined surface 4 and the second inclined surface 12 press against each other, causing the movable block 9 to move towards the fixed block 6. The cutter 2 is inserted into the first cutting inlet 8 and the second cutting inlet 11 to cut the steel pipe located in the first semi-circular groove 7 and the second semi-circular groove 10. When the movable block 9 and the fixed block 6 overlap, the first semi-circular groove 7 and the second semi-circular groove 10 form a circular structure, and the first cutting inlet 8 and the second cutting inlet 11 form a straight line. The movable block 9 has a spring-loaded structure on one side. This spring-loaded structure is used to return to its original position after the movable block 9 loses the pressure of the pusher 3, so as to carry out the next steel pipe cutting.

[0026] Furthermore, the rebound structure includes a stop block 13 welded to the top of the base 5. The stop block 13 is located on one side of the moving block 9. A slide rod 14 is welded to one end of the moving block 9 away from the second semicircular groove 10. The other end of the slide rod 14 passes through the stop block 13 and is welded to a limit block 15. A spring 16 is fitted on the surface of the slide rod 14. The spring 16 is fitted between the limit block 15 and the stop block 13. The bottom end of the push block 3 is provided with a first clearance groove 17, so that the push block 3 will not be blocked by the slide rod 14 when it continues to move downward.

[0027] Furthermore, the top of the fixing block 6 is provided with a second clearance groove 18, which extends along the height direction of the fixing block 6 to the bottom. The second clearance groove 18 is located on one side of the first cutting entrance 8 and communicates with the first cutting entrance 8. A concave mounting block 19 is welded to the bottom of the mounting plate 1, and the concave mounting block 19 is located directly above the second clearance groove 18. The surface of the cutter 2 is provided with three fixing holes 20, which are threaded holes. The concave mounting block 19 is detachably connected to the cutter 2 in the groove, which improves the convenience of replacing the cutter 2 later. The bolt 21 passes through the concave mounting block 19 and is threadedly connected to the fixing hole 20 of the cutter 2, thereby fixing the cutter 2. The concave mounting block 19 can be inserted into the second clearance groove 18 so as not to affect the normal operation of the cutter 2.

[0028] Furthermore, sleeves 22 are welded to the four corners at the bottom of the mounting plate 1, and guide rods 23 are welded to the four corners at the top of the base 5. When the mounting plate 1 moves downward, the sleeves 22 slide onto the surface of the guide rods 23 to achieve a guiding effect, which improves the stability of the mounting plate 1 during cutting.

[0029] Furthermore, the bottom of the cutter 2 has a V-shaped structure with symmetrical bevels on both sides, which improves the working efficiency of the cutter 2 when cutting. The sharp end and sharp bevels make it easier to cut.

[0030] Furthermore, the drive mechanism is driven by hydraulic cylinder 24, which is a mature existing technology and improves the stability during operation.

[0031] The working principle of this embodiment is as follows: During installation, the base 5 is first fixed on the ground, then the sleeve 22 is aligned with the guide rod 23 and the mounting plate 1 is fixed above the base 5. Next, the side of the cutter 2 with the fixing hole 20 is placed into the groove of the concave mounting block 19 and installed by bolt 21. During operation, the steel pipe is inserted between the first semicircular groove 7 and the second semicircular groove 10. Then, the hydraulic cylinder 24 is controlled to drive the mounting plate 1 to move downward. At this time, the push block 3 is pressed against the first inclined surface 4 on the moving block 9 through the second inclined surface 12, so that the moving block 9 moves towards the fixed surface. Block 6 moves and clamps the steel pipe. When the moving block 9 moves, it drives the slide rod 14 to move to one side. At the same time, the limiting block 15 squeezes the spring 16, causing the spring 16 to perform an elastic storage movement. Simultaneously, the cutter 2 inserts into the first cutting entrance 8 and the second cutting entrance 11 and then cuts the steel pipe. After completing one cut, the hydraulic cylinder 24 is controlled to drive the mounting plate 1 to move upward. Conversely, the spring 16 performs an elastic reset movement, pushing the limiting block 15 to one side, causing the slide rod 14 to drive the moving block 9 away from the fixed block 6. Repeating the above operations can complete the batch cutting of steel pipes.
