Description

Technical Field

[0001] This utility model relates to the field of pipe cutting technology, specifically a multi-angle steel pipe cutting device. Background Technology

[0002] Steel pipes are classified into round, square, rectangular, and irregular-shaped steel pipes according to their cross-sectional shape. Multi-angle steel pipe cutting is a processing technology widely used in many fields such as industrial production and construction. It is generally cut with a circular saw blade cutting machine. The motor provides power to the saw blade, making it rotate at high speed. The saw blade is usually round with sharp serrations on its edges, used to cut steel pipes. The worktable is used to place the steel pipes, and the clamps fix the steel pipes on the worktable to ensure that the steel pipes do not move during the cutting process.

[0003] Chinese patent CN212495754U discloses an environmentally friendly multi-angle steel pipe cutting device for power engineering, comprising a base plate. A working groove is formed on the left end of the upper surface of the base plate. A dual-axis motor is fixedly connected to the bottom side wall of the inner cavity of the working groove. Rotating shafts are fixedly connected to both the front and rear output ends of the dual-axis motor. A threaded rod is fixedly connected to the outer end of each rotating shaft. The outer end of the threaded rod is rotatably connected to the front and rear side walls of the inner cavity of the working groove. A movable block is screwed onto the outer wall of the threaded rod. The outer side of the movable block contacts the inner side of the working groove. A fixed connection is made to the upper surface of the movable block. A connecting plate is attached, and a fixed bending plate is fixedly connected to the inner side of the connecting plate. A rubber bending plate is fixedly connected to the inner side of the fixed bending plate. A fixing block is fixedly connected to the right end of the upper surface of the base plate. A fixing groove is opened on the left side of the fixing block. A clamping tube is fixedly connected inside the fixing block. The steel pipe is fixed by the interaction of the dual-axis motor, rotating shaft, threaded rod, moving block, connecting plate, fixed bending plate, rubber bending plate, fixing block and clamping tube. The angle of the cutting disc is adjusted by the interaction of the servo motor, working shaft, first gear, second gear, ball bearing and placement column.

[0004] However, the technical solution of this patent has the following problems:

[0005] This patent uses the combined action of a dual-axis motor, rotating shaft, threaded rod, moving block, connecting plate, fixed bending plate, rubber bending plate, fixing block and clamping tube to fix the steel pipe. The angle of the cutting disc is adjusted by the combined action of a servo motor, working shaft, first gear, second gear, ball bearing and placement column. However, it cannot perform rapid angle adjustment and secondary fixation at the same time, cannot reduce the wear of the rotating mechanism, and cannot immediately perform continuous and rapid feeding after cutting.

[0006] Therefore, those skilled in the art have provided a multi-angle steel pipe cutting device to solve the above problems. Utility Model Content

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model uses an electric rotary table to drive a multi-angle rotating device to rotate, which in turn drives a connecting block to rotate, and the connecting block to rotate an arc plate. The multi-angle rotating device performs multi-angle rotation and cuts the steel pipe. The output ends of the first and second cylinders of the fixing mechanism extend simultaneously, so that the anti-slip pads at the output ends of the first and second cylinders move towards the arc plate, quickly clamping the arc plate. This allows the multi-angle rotating device to be quickly fixed after rotating to a preset angle. The fixing mechanism is used to fix the multi-angle rotating device a second time, making the multi-angle rotating device more stable when cutting the steel pipe. At the same time, it reduces the wear of the electric rotary table used to drive the multi-angle rotating device, improves the service life of the electric rotary table, and avoids the situation where only the electric rotary table restricts rotation when the multi-angle rotating device stops rotating for cutting.

[0018] 2. By extending the output end of the sixth cylinder of the auxiliary clamping device of the rotating feeding device, the fourth clamping block moves towards the third clamping block, quickly clamping the steel pipe. Then, the output end of the fifth cylinder of the rotating feeding device shortens, causing the right side of the inclined plate to rotate towards the lower right of the frame. Next, the output end of the sixth cylinder shortens, causing the fourth clamping block to move away from the third clamping block, quickly releasing the cut steel pipe. This allows the cut steel pipe to fall along the inclined plate onto the belt conveyor and be transported away by the belt conveyor, which is beneficial for continuous and rapid feeding.

An arc-shaped slot 5 is provided on the upper side of the frame 1, and the connecting block 41 is slidably connected to the arc-shaped slot 5. The upper side of the connecting block 41 is fixedly mounted with an arc plate 42. On the lower side of the multi-angle rotating device 3 away from the electric rotary table 2, the arc plate 42 is fixedly installed on the lower side of the connecting block 41.

Anti-slip pads 45 are fixedly installed on the output ends of the first cylinder 43 and the second cylinder 44. The length of the arc plate 42 is the same as the length of the arc groove 5.

[0028] The electric rotary table 2 rotates, driving the multi-angle rotating device 3 to rotate. The multi-angle rotating device 3 rotates, driving the connecting block 41 to rotate. The connecting block 41 rotates, driving the arc plate 42 to rotate. The multi-angle rotating device 3 performs multi-angle rotation and cuts the steel pipe. The output ends of the first cylinder 43 and the second cylinder 44 of the fixing mechanism 4 extend simultaneously, causing the anti-slip pads 45 at the output ends of the first cylinder 43 and the second cylinder 44 to move towards the arc plate 42, quickly clamping the arc plate 42, so that the multi-angle rotating device 3 is quickly fixed after rotating to the preset angle.

[0029] The multi-angle rotating device 3 performs multi-angle rotation and cuts steel pipes. The fixing mechanism 4 is used to fix the multi-angle rotating device 3 for a secondary purpose, making the multi-angle rotating device 3 more stable when cutting steel pipes.

The rotation bracket 31 adjusts the angle of the multi-angle rotation device 3. The output end of the third cylinder 36 extends and drives the irregular bracket 32 ​​to rotate towards the front of the frame 1. The rotation of the irregular bracket 32 ​​drives the motor 33, gearbox 34 and saw blade 35 to rotate towards the front of the frame 1 at the same time. The rotation of the output shaft of the motor 33 is transmitted through the gearbox 34, which causes the saw blade 35 to rotate for cutting. Repeated operation can be used for continuous cutting.

[0036] The steel pipe is transported between the first clamping block 63 and the second clamping block 64 by a robotic arm or manually. The output end of the fourth cylinder 62 of the fixed clamping device 6 extends, driving the second clamping block 64 to move towards the first clamping block 63, thereby quickly clamping the steel pipe.

[0040] The output end of the sixth cylinder 84 of the auxiliary clamping device of the rotating feeding device 8 extends, driving the fourth clamping block 86 to move towards the third clamping block 85, quickly clamping the steel pipe. The output end of the fifth cylinder 83 of the rotating feeding device 8 shortens, driving the right side of the inclined plate 82 to rotate towards the lower right of the frame 1.
