Description

Technical Field

[0001] This invention relates to the field of seamless steel pipe processing technology, specifically to a cutting device for seamless steel pipe processing. Background Technology

[0002] Seamless steel pipes, with their excellent properties such as high strength, corrosion resistance, and good sealing performance, are widely used in various fields such as petroleum, chemical industry, machinery manufacturing, and construction engineering. Cutting is one of the key processes in the production and application of seamless steel pipes; its processing accuracy, efficiency, and stability directly affect the progress of subsequent processes and the quality of the final product. Currently, existing seamless steel pipe cutting devices have many shortcomings, making it difficult to meet the demands for efficient and precise processing: Firstly, the feeding, cutting, and unloading processes are not seamlessly connected, relying heavily on manual assistance for feeding or segmented processing, which prevents continuous batch processing and results in low production efficiency. Secondly, the cutting mechanism has poor adaptability; most devices can only accommodate seamless steel pipes of a single diameter. For steel pipes of different diameters, special clamps must be replaced or the equipment structure adjusted, making the operation cumbersome and time-consuming. Furthermore, the positioning accuracy and angle adjustment flexibility of the cutting mechanism are insufficient, easily leading to tilted cuts and numerous burrs. The quality issues are as follows: First, the design of the steel pipe fixing and support structure is unreasonable, resulting in poor clamping stability. During the cutting process, the steel pipe is prone to shaking or shifting, which not only affects the flatness of the cut but may also damage the cutting tool. Second, there is a lack of an intermittent feeding mechanism that matches the cutting rhythm. The conveying of the cut steel pipe and the next cutting action are prone to conflict, making it impossible to achieve precise coordination of the processing rhythm. Third, the waste collection method generated by cutting is relatively crude. Waste is prone to accumulate in the processing area, which not only pollutes the processing environment but may also affect the normal operation of the equipment and increase equipment maintenance costs.

[0003] Therefore, developing a seamless steel pipe cutting device that can achieve continuous feeding, precise cutting, stable clamping, intermittent feeding, and easy waste collection has become a technical problem that needs to be solved in this field. Summary of the Invention

[0012] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention constructs an integrated processing flow of continuous feeding, precise cutting, and intermittent unloading through the coordinated design of a steel pipe feeding machine, a slitting mechanism, a rotating mechanism, and an unloading conveyor belt. The steel pipe feeding machine can continuously transport raw steel pipes to the processing area. After the slitting mechanism completes one cut, the unloading conveyor belt intermittently transports the finished steel pipes to the next process according to the cutting rhythm, without affecting the next cut, effectively avoiding process interruption and significantly improving batch processing efficiency.

[0013] 2. The slitting mechanism adopts a dual-axis moving robotic arm combined with an adjustable electric disc cutter. The dual-axis moving robotic arm can drive the slitting mechanism to achieve precise positioning, ensuring the accuracy of the cutting position. The height of the electric disc cutter can be adjusted by the first electric telescopic rod, and the second electric telescopic rod can drive the rotating rod to adjust the cutting angle of the electric disc cutter. It can flexibly adapt to seamless steel pipes of different diameters and specifications without the need to change special clamps, reducing the complexity of operation. At the same time, the rotating mechanism drives the steel pipe to rotate at a uniform speed, which, together with the cutting action of the electric disc cutter, makes the cut evenly stressed, effectively reducing defects such as burrs and tilting, and improving cutting accuracy and cut quality.

[0014] 3. The lifting and rotating mechanisms work together to achieve stable fixation and support for the steel pipe. The lifting mechanism, through the telescopic adjustment of the first and second electric push rods, and the linkage of the connecting rod and rotating rod, can flexibly adjust the support height and support range of the bracket to adapt to the bottom support requirements of steel pipes of different diameters. In the rotating mechanism, the clamping shell and the fixing block close into a ring structure, achieving stable clamping of the steel pipe under the drive of the third electric push rod. At the same time, the limiting roller can limit the radial displacement of the steel pipe, avoiding shaking or displacement of the steel pipe during the cutting process, thus ensuring cutting stability and reducing the risk of equipment damage and safety accidents.

[0015] In summary, this invention achieves unified electrical control of components such as the dual-axis mobile robotic arm, cutting mechanism, lifting mechanism, rotating mechanism, and discharge conveyor belt through a controller, realizing automated operation of the entire process of feeding, clamping, supporting, cutting, and unloading without frequent manual intervention and adjustment. This not only reduces human error but also significantly reduces the labor intensity of operators and improves the stability and consistency of the processing. Attached Figure Description

[0027] The following mainly introduces the working principle and process, and the specific work is as follows.

[0028] Step 1: In use, the steel pipe product is pushed to the position of the rotating mechanism 7 by the steel pipe feeding machine 9, so that one end of the steel pipe product is on the discharge conveyor belt 8. The controller 2 sequentially starts the discharge conveyor belt 8, the third electric push rod 75, the first electric push rod 64 and the second electric push rod 68. The third electric push rod 75 extends itself to push the clamping housing 74 to move backward. Under the limiting action of the second slot rod 73, the clamping housing 74 and the fixing block 78 are closed outside the steel pipe product. The first electric push rod 64 extends itself to push the first connecting seat 65 to move downward. Then, the first connecting seat 65 drives the rear end of the rotating rod 66 to move upward with the pin joint of the connecting rod 63 as the apex. The rotating rod 66 drives the third mounting seat 67 to move upward and unfold. The second electric push rod 68 extends itself to push the second connecting seat 69. Under the limiting action of the first slot rod 612, the second connecting seat 69 drives the bracket 610 to move upward to support the bottom of the steel pipe product. Step 2: The operator controls the controller 2 to sequentially activate the dual-axis mobile robotic arm 3, the first electric telescopic rod 42, and the second electric telescopic rod 46. The dual-axis mobile robotic arm 3 drives the cutting mechanism 4 to move in the dual-axis direction, so that the first electric telescopic rod 42 extends to drive the first mounting base 43 to move downward, thereby causing the first mounting base 43 to drive the rotating rod 44 and the electric disc cutter 45 to make fine adjustments. The second electric telescopic rod 46 extends to push the rotating rod 44 to rotate inward with the pivot point of the first mounting base 43 as the apex, thereby causing the rotating rod 44 to drive the electric disc cutter 45 to move inward and contact the outer wall of the steel pipe product. The motor 715 drives the two second pulleys 716 to rotate. Since the first pulley 714 and the second pulley 716 are connected by belt transmission, the first pulley 714 is driven by the rotational force of the second pulley 716. The rotating shaft 712 drives the second gear 713 to rotate. Under the rotational force of the second gear 713, the first gear 711 drives the rotating roller 710 to rotate. This causes the steel pipe product inside the rotating mechanism 7 to rotate under the rotational force of the rotating roller 710 and under the limiting action of the limiting roller 77, so that the electric disc cutter 45 cuts the steel pipe product. The cut steel pipe product is then transported to the next process via the discharge conveyor belt 8. Since the steel pipe feeder 9 can continuously feed the steel pipe, the slitting mechanism 4 can cut the steel pipe product. When the discharge conveyor belt 8 transports the cut steel pipe product, the slitting mechanism 4 performs the next cut on the steel pipe product. Therefore, there will be a certain time interval when the discharge conveyor belt 8 transports the cut steel pipe product, thus completing intermittent feeding. That is, this technical solution can achieve the effect of continuous cutting and intermittent feeding of steel pipe products.
