[0024] Example 1 See also Figures 1 to 6 The present invention provides a construction steel pipe cutting machine, comprising a base 1, a cutting mechanism 2 rotatably arranged on the base 1, the cutting mechanism 2 comprising a mounting frame 2-1 rotatably arranged on the base 1, a motor 2-2 and a saw blade 2-3 rotatably driven by the motor 2-2 arranged on the mounting frame 2-1; A swing gear 2-4 is fixedly arranged on both sides of the mounting frame 2-1, and the swing gear 2-4 is fan-shaped. The rotation axis of the swing gear 2-4 is coaxial with the rotation axis of the mounting frame 2-1. One side of each swing gear 2-4 is respectively engaged with a driving gear 2-5, and each driving gear 2-5 is rotatably arranged on the base 1, and the two driving gears 2-5 are coaxially fixed through a connecting rod; The base 1 is also provided with a clamping mechanism 3 for clamping the steel pipe; A driving gear 2 - 5 close to the clamping mechanism 3 is linked to the clamping mechanism 3 .

[0025] The clamping structure includes a fixing frame 3-1 fixedly arranged on the base 1, a rotating drum 3-2 is rotatably arranged on the fixing frame 3-1, and a clamping unit 3-3 is fixedly arranged at each end of the rotating drum 3-2; A rotating worm wheel 3-4 is coaxially fixed in the middle of the rotating drum 3-2, and a rotating worm 3-5 is rotatably arranged on the fixed frame 3-1. The rotating worm 3-5 is meshed with the rotating worm wheel 3-4. One end of the rotating worm 3-5 extends to the outside of the fixed frame 3-1 and is coaxially fixed with a rotating hand wheel 3-6.

[0026] The steel pipe to be cut is placed in the drum 3-2, so that one end of the steel pipe to be cut is exposed to a suitable length, and the steel pipe is clamped by the clamping unit 3-3. The user rotates the rotating hand wheel 3-6. Since the rotating hand wheel 3-6 is coaxially fixed with the rotating worm 3-5, the rotation of the rotating hand wheel 3-6 will drive the rotating worm 3-5 to rotate. The rotating worm 3-5 is meshed with the rotating worm wheel 3-4 coaxially fixed in the middle of the drum 3-2. According to the transmission principle of the worm gear, the rotation of the rotating worm 3-5 will drive the rotating worm wheel 3-4 to rotate, thereby driving the drum 3-2 to rotate on the fixed frame 3-1.

[0027] The rotation drives the steel pipe to rotate during the rotation. When the saw blade 2-3 cuts the steel pipe, the contact point between the saw blade 2-3 and the steel pipe is constantly changing. Compared with the one-way cutting of the saw blade 2-3 when the steel pipe is fixed, the rotating steel pipe can make the cutting force of the saw blade 2-3 on the steel pipe more evenly distributed. For example, when cutting a thicker-walled steel pipe, if the steel pipe does not rotate, the saw blade 2-3 is prone to vibrate during the cutting process due to excessive local force, resulting in wavy lines on the cut surface. The rotation of the steel pipe can effectively reduce this situation and make the cut surface smoother.

[0028] At the same time, the rotation of the steel pipe enables the saw blades 2-3 to cut into the steel pipe material from different angles, avoiding material tearing and excessive extrusion that may occur during fixed cutting, which helps to form a neater incision on the cutting edge and reduce the generation of burrs.

[0029] Since the rotation of the steel pipe makes the cutting process of the saw blade 2-3 smoother, the saw blade 2-3 can cut more material per unit time. For example, when cutting steel pipes of the same diameter and wall thickness, the cutting method of rotating the steel pipe can appropriately increase the feed speed of the saw blade 2-3 without significantly affecting the cutting quality. This can effectively shorten the cutting time and improve work efficiency for batch cutting of construction steel pipes.

[0030] The rotation of the steel pipe can change the relative motion state between the saw blade 2-3 and the steel pipe, making the resistance of the saw blade 2-3 more stable during the cutting process. This stable resistance helps to maintain the cutting performance of the saw blade 2-3 and reduce the jamming of the saw blade 2-3 caused by excessive resistance. The saw blade 2-3 can cut into and remove the steel pipe material more stably, thereby speeding up the cutting process.

[0031] A driving gear 2-5 near the clamping mechanism 3 is linked to the rotating worm 3-5.

[0032] Furthermore, a transmission shaft is arranged between the driving gear 2-5 and the rotating worm 3-5, and universal couplings are arranged at both ends of the transmission shaft. The couplings can make the driving gear 2-5 and the rotating worm 3-5 not on the same axis, and can realize continuous rotation of the two connected axes when there is an axis angle, and reliably transmit torque and motion.

[0033] When the user turns the rotating handwheel 3-6, the driving gear 2-5 will be driven to rotate synchronously, and the two driving gears 2-5 will respectively drive the swinging gear 2-4 to rotate, thereby driving the mounting frame 2-1 to swing around the rotating axis on the base 1, so that the saw blade 2-3 can automatically cut the steel pipe. The user only needs to control the rotation rhythm and direction of the rotating handwheel 3-6 and continuously input power to the driving gear 2-5, and the saw blade 2-3 will continue to cut along the predetermined path. There is no need for manual intervention in the feeding, angle adjustment and other operations of the saw blade 2-3, and the cutting process is continuous and efficient.

[0034] The clamping unit 3-3 includes a chuck 3-7 fixedly arranged at one end of the rotating drum 3-2, and two claws 3-8 are slidably arranged on the chuck 3-7. The two claws 3-8 are arranged opposite to each other, and a cross bar 3-9 is fixedly arranged at one end opposite to each claw 3-8, and a V-shaped groove is arranged at the other end.

[0035] Place the steel pipe between the claws 3-8 corresponding to the two chucks 3-7, and move the claws 3-8 so that the V-groove of the claws 3-8 fits tightly against the outer wall of the steel pipe. The V-groove design can better adapt to the shape of the round steel pipe, increase the contact area and friction, and ensure a secure clamping.

[0036] Two control rods 3-10 are rotatably arranged on the chuck 3-7, and the two control rods 3-10 are respectively located on both sides of the claw 3-8, and spiral grooves are respectively arranged at the two ends of each control rod 3-10; A through hole is respectively formed at the two ends of the crossbar 3-9, and a convex block is arranged in the through hole, and the convex block slides in the spiral groove; A driven gear 3-11 is fixedly arranged in the middle of each control rod 3-10.

[0037] By rotating the two control rods 3-10, the spiral groove and the protrusion are linked to make the cross bar 3-9 drive the claws 3-8 to move smoothly towards each other, thereby driving the claws 3-8 to move to one side of the steel pipe, and the V-shaped groove of the claws 3-8 gradually fits the outer wall of the steel pipe.

[0038] The spiral grooves at both ends of the control rod 3-10 are arranged relatively to ensure that the two claws 3-8 clamp the steel pipe synchronously, avoid unilateral excessive clamping causing the steel pipe to deviate, make the steel pipe always coaxial with the rotating drum 3-2, and ensure the stability of the steel pipe during rotation.

[0039] A shaft sleeve 3-12 is slidably arranged on each of the rotating drums 3-2, and a plurality of annular grooves 3-13 are arranged in an array on the outer side of the shaft sleeve 3-12. An input gear 3-14 is rotatably arranged on the fixed frame 3-1, and the teeth of the input gear 3-14 mesh with one of the grooves 3-13; The design of the groove 3-13 can ensure that the sleeve 3-12 will not affect the input gear 3-14 when it rotates, and when the input gear 3-14 rotates, it can drive the sleeve 3-12 to move along the axis of the drum 3-2; Two racks 3-18 are fixedly provided at one end of the sleeve 3-12 close to the chuck 3-7, and each rack 3-18 is respectively meshed with an adjacent driven gear 3-11.

[0040] When the sleeve 3-12 moves, it drives the control rod 3-10 to rotate through the rack 3-18. With the help of the spiral groove and the protrusion, the cross bar 3-9 drives the claws 3-8 to move smoothly towards each other, thereby driving the claws 3-8 to move to one side of the steel pipe, and the V-shaped groove of the claws 3-8 gradually fits the outer wall of the steel pipe.

[0041] A clamping worm wheel 3-15 is also rotatably arranged on the fixed seat, and the clamping worm wheel 3-15 is coaxially fixed with the input gear 3-14, and one side of the clamping worm wheel 3-15 is meshed with the clamping worm 3-16; The two clamping worms 3-16 are coaxially fixed via a connecting rod; A clamping hand wheel 3-17 is coaxially fixedly arranged on one of the clamping worms 3-16.

[0042] The operator rotates the clamping hand wheel 3-17 to make the two clamping worms 3-16 rotate synchronously, driving the clamping worm wheel 3-15 meshing with it to rotate, and the clamping worm wheel 3-15 is coaxial with the input gear 3-14, thereby driving the input gear 3-14 to rotate. The teeth of the input gear 3-14 act on the groove 3-13 outside the sleeve 3-12, causing the sleeve 3-12 to slide on the drum 3-2, and the rack 3-18 at the end of the sleeve 3-12 follows, driving the driven gear 3-11 meshing with it to rotate, and finally through the control rod 3-10, the spiral groove and other transmissions, the claws 3-8 move smoothly towards each other, and the V-shaped groove fits tightly against the outer wall of the steel pipe to achieve clamping.

[0043] When the present invention is used, the steel pipe to be cut is placed in the rotating drum 3-2, so that one end of the steel pipe to be cut is exposed to a suitable length, and the steel pipe is clamped by the clamping unit 3-3. The user rotates the rotating hand wheel 3-6. Since the rotating hand wheel 3-6 is coaxially fixed with the rotating worm 3-5, the rotation of the rotating hand wheel 3-6 drives the rotating worm 3-5 to rotate, thereby driving the rotating drum 3-2 to rotate on the fixed frame 3-1. When the user turns the rotating handwheel 3-6, the driving gear 2-5 will be driven to rotate synchronously, and the two driving gears 2-5 will respectively drive the swinging gear 2-4 to rotate, thereby driving the mounting frame 2-1 to swing around the rotating axis on the base 1, so that the saw blade 2-3 can automatically cut the steel pipe. The user only needs to control the rotation rhythm and direction of the rotating handwheel 3-6 and continuously input power to the driving gear 2-5, and the saw blade 2-3 will continue to cut along the predetermined path. There is no need for manual intervention in the feeding, angle adjustment and other operations of the saw blade 2-3, and the cutting process is continuous and efficient.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
