Description

Technical Field

[0001] The present invention relates to the technical field of pipe processing, and more particularly to a cutting device for pipe processing. Background Art

[0002] A pipe cutting device is a device used to cut pipes to a specified length. It typically consists of a cutting mechanism with a cutting blade. When used, the blade is placed against the pipe and gradually applied pressure. The blade gradually cuts along the pipe surface, creating a cut and cutting the pipe to the specified length.

[0003] When using a pipe processing cutting device to cut pipes, the pipes need to be fixed to prevent the pipes from rotating as the blade rotates during the cutting process, affecting the cutting effect. In the process of fixing pipes, existing cutting devices usually use a single-point clamping method to fix pipes of various sizes, and in order to ensure the fixing effect of the pipes, a large pressure needs to be applied to fix the pipes. Such a fixing method will cause the pipes to be subjected to a large pressure per unit area, so it is easy to cause the pipes to deform during fixing. The pipes will get stuck due to the deformation during the subsequent cutting process, and the deformation of the pipes will also affect the cutting accuracy of the pipes. Summary of the Invention

[0018] (2) This solution forms an arc-shaped contact surface that fits the outer surface of the pipe by making multiple positioning pins, and uses multiple driving springs to apply thrust to ensure that each positioning pin can be tightly attached to the surface of the pipe, thereby achieving a stable and uniform clamping effect, significantly enhancing the adaptability to pipes of different sizes, and enabling it to flexibly adapt to pipes of various specifications and sizes.

[0019] (3) This solution uses an active straightening shaft in conjunction with multiple driven straightening shaft assemblies to straighten the pipe during the pipe cutting operation. Even if the pipe has been straightened in advance, it may still be deformed and bent due to various factors during the subsequent transportation and storage process. This potential bending risk has an adverse effect on the pipe cutting operation. Therefore, immediate straightening can effectively prevent the problem of pipe bending during the cutting preparation stage that may cause damage to the cutting accuracy, further improving the cutting accuracy and overall cutting quality of the pipe.

[0038] The first driven pry plate 323 is rotatably connected to the surface of the third rotating frame 334, and the lower surface of the left end of the first driven pry plate 323 is fixedly connected to the second connecting column 325. The lower surface of the left end of the active pry plate 315 is fixedly connected to the first connecting column 318. The surfaces of the first connecting column 318 and the second connecting column 325 are fixedly sleeved with a plurality of second driven pry plates 324. The right ends of the plurality of second driven pry plates 324 are respectively rotatably connected to the plurality of first rotating frames 321. The active pry plate 315 is fixedly connected to the left end of the first driven pry plate 323. The cross bar 308 is connected. When the active pry plate 315 rotates, the first driven pry plate 323 can be synchronously driven to rotate by connecting the cross bar 308, thereby reducing the number of operating steps in the fixing process. The upper surfaces of the multiple positioning pins 309 are provided with abutment grooves 314, and the end faces of the multiple groups of transversely arranged positioning pins 309 are fixedly connected with rubber strips 307. When the positioning pins 309 abut against the pipe fittings, the rubber strips 307 can prevent the positioning pins 309 from directly contacting the pipe fittings, further reducing the possibility of deformation of the pipe fittings. In addition, the rubber strips 307 can increase friction and improve the fixing effect on the pipe fittings.

[0039] Among them, two brackets 319 are fixedly connected to the left side of the top of the stand 316, and a hanger 326 is fixedly connected between the two brackets 319. Slots 328 are provided on both sides of the interior of the hanger 326. The left end of the upper surface of the active pry plate 315 is fixedly connected to a plug column 327. Two plug blocks 329 are slidably connected to the top of the plug column 327. The ends of the two plug blocks 329 close to each other are respectively fixedly connected to a middle guide pin 331 and two side guide pins 330. The lower surfaces of the multiple positioning pressure plates 310 are fixedly connected to rubber pads 317. The positioning pressure plates 310 are pressed against the When the blocks 329 are aligned with the slots 328, the reset springs 332 will push the blocks 329 into the slots 328, thereby fixing the positions of the multiple positioning plates 310. The surfaces of the two blocks 329 are fixedly connected with handles 320, so that the two handles 320 can be moved in a direction close to each other, so that the two blocks 329 can be disengaged from the slots 328.

[0040] By adopting the above technical solution, when cutting the pipe, the pipe is placed between the movable seat 305 and the fixed seat 306, and the pipe is adjusted so that the cutting portion of the pipe is located directly below the cutting blade on the cutting assembly 2, and then the first motor 301 drives the driving screw 304 to rotate, so as to move the movable seat 305 toward the fixed seat 306 until the plurality of positioning pins 309 are all against the surface of the pipe, and as the movable seat 305 continues to advance, the plurality of positioning pins 309 are all against the surface of the pipe, so that the plurality of positioning pins 309 form The arc surface fits the outer surface of the pipe and multiple driving springs 313 provide thrust so that the positioning pins 309 can be firmly pressed against the surface of the pipe. Then, hold the handle 303 and lift it up to press the multiple positioning pressure plates 310 against the abutment grooves 314. In this way, the positions of the multiple positioning pins 309 are fixed by the friction between the rubber pads 317 and the abutment grooves 314, so that the pipe can be clamped by the multiple positioning pins 309, which can avoid local stress concentration on the pipe and excessive pressure per unit area leading to deformation of the pipe, and can adapt to pipes of various sizes.

[0041] When the handle 303 is lifted up, the plug column 327 will also be driven to move upward, so that the inclined surface of the plug block 329 can be squeezed against the lower surface of the hanger 326, causing the plug block 329 to retract into the plug column 327. At this time, the return spring 332 is in a compressed state, and as the plug block 329 continues to move, the return spring 332 will push the plug block 329 into the slot 328 when the plug block 329 is aligned with the slot 328, thereby fixing the positions of multiple positioning pressure plates 310 to prevent the positioning pressure plates 310 from loosening, and the rubber pad 317 is deformable and elastic, so when the positioning pressure plate 310 is pressed on the abutment groove 314, the friction between the rubber pad 317 and the abutment groove 314 is used to fix the positions of multiple positioning pins 309, thereby maintaining the clamping effect on the pipe fitting. When releasing the fixation of the positioning pin 309, the two gripping handles 320 are held simultaneously and moved toward each other, so that the two inserting blocks 329 can be disengaged from the slots 328 to release the fixation of the positioning pin 309 and facilitate the movement of the pipe fitting.

[0042] like Figure 9 and Figure 10 As shown, a straightening mechanism is arranged on the left side of the cutting table 1, and the straightening mechanism includes a placement rack 401 fixedly connected to the left side of the cutting table 1, and a mounting seat 404 is fixedly connected to the upper surface of the right side of the placement rack 401, and a correction frame 403 is fixedly connected to the upper surface of the mounting seat 404, and a plurality of driven shafts 406 are internally rotatably connected to the correction frame 403, and the surfaces of the plurality of driven shafts 406 are fixedly sleeved with driven correction shafts 405, and the pipe fittings can be straightened by the plurality of driven correction shafts 405 to prevent the pipe fittings from bending before cutting and causing a decrease in the cutting accuracy of the pipe fittings. The left end of the correction frame 403 is internally rotatably connected with a rotating shaft 408, and the surface of the rotating shaft 408 is fixedly sleeved with an active correction shaft 407.

[0043] Among them, a second motor 402 is fixedly connected to the upper surface of the right side of the placement rack 401. The second motor 402 drives the active correction shaft 407 to rotate to realize the movement of the pipe fitting. The output shaft of the second motor 402 is fixedly connected to the front end of the rotating shaft 408. The active correction shaft 407 and the multiple driven correction shafts 405 are staggered with each other.

[0044] By adopting the above technical solution, when cutting the pipe, the pipe is located between the active correction shaft 407 and multiple driven correction shafts 405, and the active correction shaft 407 is driven to rotate by the second motor 402, and the active correction shaft 407 drives the pipe to pass through the correction frame 403. Therefore, during the movement of the pipe, the pipe can be straightened by multiple driven correction shafts 405, which can prevent the pipe from bending before cutting, resulting in a decrease in the cutting accuracy of the pipe and affecting the quality of the pipe cutting.

[0045] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed by the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
