Description

Technical Field

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

[0002] This stainless steel seamless pipe cutting device is a specialized processing equipment designed for the characteristics of stainless steel seamless pipes, such as high hardness, easy blade sticking, and easy burr deformation at the cut. It mainly consists of a clamping and positioning mechanism, a cutting execution component, a feed adjustment mechanism, and a waste collection component. The device can stably clamp steel pipes of different diameters, limit the cutting position, and complete the pipe cutting through mechanical cutting. It controls the cutting feed speed to reduce problems such as burrs, edge collapse, and pipe wall deformation at the cut. It is suitable for cutting seamless steel pipes of different specifications, reduces pipe slippage during clamping, and simultaneously collects cutting debris and waste, improving the quality of the cut surface and processing efficiency, thus meeting the needs of batch cutting and processing of stainless steel pipes.

[0003] However, existing seamless steel pipe cutting devices lack a positioning and clamping structure for the steel pipe during use. They rely solely on the cutting force generated by the downward pressure of the cutting blade to achieve the positioning and clamping of the steel pipe. This can easily lead to slippage, displacement, and vibration during the steel pipe cutting process, resulting in tilted cut surfaces and large burrs, thus affecting the cutting quality and finished product qualification rate of the steel pipe. Summary of the Invention

[0004] The purpose of this invention is to provide a cutting device for stainless steel seamless pipes. By setting a fixing part, it solves the problem that existing seamless pipe cutting devices lack a positioning and clamping structure for the steel pipe during use. They rely solely on the cutting force generated by the downward pressure of the cutting blade to achieve the positioning and clamping of the steel pipe. This leads to phenomena such as movement, displacement, and vibration during the cutting process, resulting in tilted cut surfaces and large burrs, which affect the cutting quality and finished product qualification rate of the steel pipe.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a cutting device for seamless stainless steel pipes, comprising a worktable and a guide roller assembly disposed on the top of the worktable, with a steel pipe rotatably connected to the guide roller assembly.

Two fixing blocks are fixedly connected to the outer wall of several slide rods. A connecting rod is rotatably connected to each of the two fixing blocks. Two connecting rods are hinged to each of the two connecting rods. The tops of the two corresponding connecting rods are hinged to the upper slide plate, and the bottoms of the two corresponding connecting rods are hinged to the lower slide plate. The two upper guide rollers and the two lower guide rollers are in contact with the steel pipe.

[0006] Furthermore, the moving part includes a moving component disposed on a worktable; and a power component disposed on the moving component.

[0009] Furthermore, the moving component includes a slide groove formed on the top of the workbench, two slide rods are fixedly connected in the slide groove, and a slide plate is slidably connected to the outer wall of the two slide rods. A screw is rotatably connected in the slide groove, the screw passes through the slide plate, the outer wall of the screw is threadedly connected to the slide plate, a protective component is provided on the screw, and the left end of the screw extends outside the workbench. The protective component includes two telescopic protective sleeves provided on the outer wall of the screw.

[0010] Furthermore, the power assembly includes a motor fixedly connected to the left side of the worktable, and the output shaft of the motor is fixedly connected to a screw via a coupling.

[0011] Furthermore, the reinforcement assembly includes a bottom frame fixedly connected to the top of the slide plate one, two guide rollers one rotatably connected to the top of the bottom frame, a plurality of slide rods three fixedly connected to the top of the bottom frame, a slide plate two slidably connected to the outer walls of the plurality of slide rods three, and two guide rollers two fixedly connected to the bottom of the slide plate two.

[0012] Furthermore, the limiting component includes a top plate two fixedly connected to the top of several sliding rods three, and a knob screw is threadedly connected to the top plate two, the bottom end of the knob screw being rotatably connected to the sliding plate two.

[0013] The present invention has the following beneficial effects: 1. The fixing part of this invention is the core stable structure for steel pipe cutting operations. After the steel pipe is initially positioned, it can perform secondary clamping and limiting of the steel pipe at the cutting position. It can comprehensively constrain the displacement, offset and high-frequency vibration of the steel pipe, changing the single fixing method of traditional cutting that only relies on the pressure of the cutting blade. This part effectively makes up for the lack of positioning stability of traditional cutting devices, prevents the problems of movement and shaking during steel pipe cutting from the root, effectively avoids quality defects such as tilted cutting surface and large burrs, greatly improves the flatness and accuracy of steel pipe cutting, steadily improves the qualification rate of steel pipe cutting products, and provides a solid structural guarantee for cutting operations. 2. The moving part of this invention plays a core role in the feeding and cutting position adjustment of the steel pipe. It can drive the clamped and fixed steel pipe to move smoothly and accurately, flexibly adjust the cutting point of the steel pipe, and adapt to the cutting needs of steel pipes of different lengths and specifications. This part realizes automated feeding of steel pipes, replacing the manual adjustment method, effectively improving the accuracy of steel pipe position adjustment and work efficiency, while ensuring the stability of the steel pipe displacement process, avoiding misalignment or loosening of the steel pipe during the adjustment process, ensuring the accuracy of the cutting position each time, adapting to batch and standardized steel pipe cutting production operations, and improving the adaptability and production efficiency of the equipment. 3. The reinforcing part of this invention serves as a pre-clamping and positioning structure for the steel pipe. It can complete the initial wrapping clamping and fixing before the steel pipe is cut, pre-positioning and pre-reinforcing the steel pipe, effectively regulating the placement of the steel pipe, and preventing the steel pipe from tilting or shifting before processing. This part can work with the fixing part to form a double clamping protection system, strengthening the overall fixing effect of the steel pipe layer by layer, further improving the structural stability of the entire steel pipe cutting process. At the same time, it can be adapted to the clamping and positioning of seamless steel pipes with different outer diameter specifications, improving the versatility of the equipment. It controls the basic cutting accuracy from the pre-positioning stage, laying a good foundation for subsequent accurate cutting and eliminating cutting defects.

[0022] It should be noted that the control of the cutting device 114, electric push rod 221 and motor 321 in this application can all be achieved by using a program set in the control panel and inputting relevant parameters as needed for automated control. This control method can be achieved using existing technologies, such as PLC.

[0023] In use, the steel pipe 113 can first be passed through the guide rollers 412 and 415 on the bottom frame 411 and the slide plate 414, then through the upper guide roller 214 and lower guide roller 216 on the upper slide plate 213 and the lower slide plate 215, and finally the steel pipe 113 contacts the guide roller group 112; then, the knob screw 422 on the top plate 421 is rotated downwards, the knob screw 422 will drive the slide plate 414 and the two guide rollers 415 at its bottom, and the four slide rods 413... Under the guidance of the guide rollers, the steel pipe 113 moves smoothly downwards, allowing the two guide rollers 415 to cooperate with the two guide rollers 412 on the base frame 411, thus completing the initial clamping of the steel pipe 113. After the steel pipe 113 is clamped, the motor 321 can be started. The motor 321, through the screw 314 and guided by the two slide rods 312, causes the slide plate 313 to drive the steel pipe 113 clamped on the base frame 411 to move under the guidance of the guide roller group 112 until the appropriate cutting distance is adjusted. Before cutting, the electric push rod 221 can be activated. The electric push rod 221 will drive the upper slide plate 213 and its two upper guide rollers 214 to move closer to the top of the steel pipe 113. During the movement of the upper slide plate 213, its two sides can be hinged through the two connecting rods 218 and multiple connecting rods 219, so that the lower slide plate 215 can drive its two lower guide rollers 216 to move closer to the upper slide plate 213 and its two upper guide rollers 214. Under the guidance of the four sliding rods 211, the steel pipe 113 is clamped and fixed again. This effectively prevents the steel pipe 113 from moving, shifting, and vibrating during cutting, and avoids the problems of tilted cut surface and excessive burrs. After the steel pipe 113 is fixed and stable, the cutting device 114 can be activated. With the cooperation of the guide roller group 112, the cutting device 114 can keep the steel pipe 113 rotating during the cutting process, thereby ensuring the flatness of the cut surface and the cutting quality.
