Strip steel is also known as steel strip. Its width is generally within 1300mm, and the length varies slightly depending on the size of each coil. By folding and welding the two sides of the strip steel, it can be continuously rolled into a steel pipe. Then, the steel pipe is cut according to requirements to produce steel pipes with different outer diameters or lengths. On the production line of rolling strip steel into steel pipes, it is necessary to cut the linear steel pipes along the line.

[0017] Furthermore, a sixth linear module is installed on the third frame, and the movable end of the sixth linear module is fixedly connected to the upper pressure plate.

[0018] Compared with the prior art, the linear steel pipe continuous floating cutting device of the present invention has the following advantages: (1) The linear steel pipe continuous floating cutting device of the present invention can support the height of the linear steel pipe through the support component, so that the linear steel pipe is kept coaxial with the detection component and the sawing component, so as to meet the sawing of steel pipes with different outer diameter specifications. The detection component detects the consistency of the outer diameter of the steel pipe and whether it needs to be straightened, so as to improve the product quality. After sawing, the conveying component moves the sawed steel pipe away from the sawing component, so as to facilitate continuous production. The cutting device has high cutting efficiency and also has the function of steel pipe quality detection. It can meet the continuous production of different product specifications and has high versatility.

[0019] (2) In the linear steel pipe continuous floating cutting device of the present invention, the transmission gear of the rotating first rotary motor can rotate circumferentially around the periphery of the first gear. The first gear is concentric with the first sleeve. The linear steel pipe is located inside the first sleeve and is concentric with the first sleeve, thereby driving the first back plate, the first sleeve and the cutting component to rotate circumferentially relative to the periphery of the linear steel pipe, so as to achieve the purpose of cutting the linear steel pipe circumferentially.

[0020] (3) The linear steel pipe continuous floating cutting device of the present invention has a cutting motor that can drive the cutting slice to rotate. The rotating cutting slice is used to cut the linear steel pipe. Cutting the steel pipe by the cutting slice can reduce the cutting pressure of the cutting slice on the outside of the steel pipe and prevent the problem of deformation of the cutting end face of the steel pipe due to excessive pressure. The second linear module can push the first sliding plate, the first connecting plate and the cutting slice closer to or away from the linear steel plate in order to meet the cutting requirements. The first spring is a floating elastic structure of the cutting motor and the cutting slice, which prevents the second linear module from forcibly squeezing the cutting slice onto the surface of the steel pipe and causing damage to the cutting slice, thereby improving the service life of the parts. At the same time, the first spring can provide a clamping force for the cutting slice to contact the surface of the steel pipe.

[0021] (4) The linear steel pipe continuous floating cutting device of the present invention is equipped with a trimming component. After the cutting blade cuts the outer periphery of the steel pipe, cutting chips and sharp nicks will remain on the outer periphery of the steel pipe. The trimming component can remove the cutting chips and sharp nicks on the outer periphery of the steel pipe end to prevent scratches to the equipment in the subsequent process or harm to the workers.

[0022] (5) The linear steel pipe continuous floating cutting device of the present invention has one end of the trimming head that can abut against the sawing gap of the linear steel pipe. When the first back plate rotates relative to the steel pipe, the trimming head can simultaneously remove the cutting chips and the sharp nicks adhering to the sawing gap as the steel pipe is sawed. The removal is rigid and the trimming quality is controllable.

[0023] (6) The linear steel pipe continuous floating cutting device of the present invention can release the distance between the adjusting block and the second sliding plate by turning the adjusting bolt, and make the adjusting block move away from the second sliding plate by the third spring, thereby realizing the axial movement of the trimming head relative to the linear steel pipe, which makes it easy for the operator to adjust the position of the trimming head relative to the sawing gap so as to be suitable for slices of different thicknesses. The third linear module is used to drive the adjusting component and the trimming head to move closer to or away from the outer periphery of the steel pipe so as to bring the trimming head into the working position and away from the working position. By turning the adjusting rod, the trimming head can move closer to or away from the outer periphery of the steel pipe, which facilitates the fine adjustment of the working position of the trimming head and meets the production requirements.

[0024] (7) The linear steel pipe continuous floating cutting device of the present invention has two detection units rotating relative to the outer periphery of the steel pipe. The execution ends of the two detection units respectively abut against the outer periphery of the steel pipe. The consistency of the outer diameter of the steel pipe and whether the steel pipe is bent are detected by measuring the fluctuation of the distance between the two execution ends, so as to record the product quality data of each sawing segment, improve the detection efficiency, and ensure product quality.

[0025] (8) The linear steel pipe continuous floating cutting device of the present invention has a ball bearing that is rolled around and connected to the outer periphery of the steel pipe to reduce the friction between the ball bearing and the steel pipe. The fourth spring is a floating structure of the ball bearing and the top rod to prevent the outer periphery of the steel pipe from being squeezed hard against the ball bearing when the steel pipe changes diameter. The retaining ring can limit the outward protrusion limit of the ball bearing to prevent the top rod and the ball bearing from sliding out of the fifth sliding hole. A grating ruler is set on the top rod and a photoelectric probe is set in the fifth sliding hole. When the top rod slides due to the change in the outer diameter of the steel pipe, the floating amount of the top rod can be measured by the grating ruler. During the process of the steel pipe moving relative to the detection unit, the change in the outer diameter of the steel pipe can be measured by the distance between the execution ends of the two opposing detection units. The floating amount of each detection unit can be used to determine whether the steel pipe needs to be straightened.

[0026] (9) The linear steel pipe continuous floating cutting device of the present invention has a conveying motor that can drive the upper pressure roller to rotate, and through differential rotation, the cut steel pipe can be quickly separated from the floating base and transferred to the next process. The third screw can adjust the relative height of the lower pressure plate so that the lower pressure roller can meet the usage requirements of steel pipes with different outer diameters.

[0032] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] like Figures 1-13 As shown, the continuous floating cutting device for linear steel pipes includes a floating base 1 and a support assembly 2, a support frame 4, a clamping assembly 6, and a conveying assembly 7 respectively mounted on it. The floating base 1 can slide on a guide rail 13, which is set on a foundation. A detection assembly 3 and a sawing assembly 5 are respectively arranged on both sides of the support frame 4. The support assembly 2 is located on one side of the detection assembly 3, and the clamping assembly 6 is located between the sawing assembly 5 and the conveying assembly 7. The outer periphery of the linear steel pipe can overlap the upper periphery of the support assembly 2. The detection assembly 3 is used to detect the consistency of the circumferential or axial dimensions of the linear steel pipe, and the clamping assembly 6 is used to clamp... The conveying assembly 7, which holds the outer periphery of the linear steel pipe, can drive the cut steel pipe to move linearly. The supporting assembly 2 can support the height of the linear steel pipe, keeping it coaxial with the detection assembly 3 and the sawing assembly 5, so as to meet the sawing of steel pipes with different outer diameter specifications. The detection assembly 3 detects the consistency of the outer diameter of the steel pipe and whether straightening is required, so as to improve product quality. After sawing, the conveying assembly 7 moves the sawn steel pipe away from the sawing assembly 5 for continuous production. This cutting device has high cutting efficiency and also has the function of steel pipe quality inspection. It can meet the continuous production of different product specifications and has high versatility.

[0034] The sawing assembly 5 includes a first sleeve 51, one end of which is rotatably sleeved onto one side of a support frame 4, and a first gear 52 is fixedly installed on the support frame 4. The inner ring of the first gear 52 is located around the first sleeve 51. A first back plate 53 is fixedly installed at the other end of the first sleeve 51. A first rotary motor 54 is fixedly installed on one side of the first back plate 53. The outer ring of the transmission gear of the first rotary motor 54 meshes with the outer ring of the first gear 52. A cutting assembly is installed on the other side of the first back plate 53. The outer ring of the linear steel pipe is located within the inner ring of the first sleeve 51, and the cutting assembly is used to cut the outer ring of the linear steel pipe. The transmission gear of the rotating first rotary motor 54 can rotate circumferentially around the outer ring of the first gear 52. The first gear 52 is concentric with the first sleeve 51. The linear steel pipe is located inside the first sleeve 51 and is concentric with the first sleeve 51, thereby driving the first back plate 53, the first sleeve 51, and the cutting assembly to rotate circumferentially relative to the outer ring of the linear steel pipe, achieving the purpose of circumferentially cutting the linear steel pipe.

[0035] The cutting assembly includes a slice 55, the middle of which is fixedly mounted to the drive shaft of a cutting motor 56. The cutting motor 56 is fixedly mounted to a first slide plate 57, and a first slide rail 58 is provided on a first back plate 53. One side of the first slide plate 57 is slidably connected to the periphery of the first slide rail 58. A first connecting plate 59 is provided at one end of the first slide plate 57, and a second sliding hole is provided on the first connecting plate 59. A second linear module 510 is mounted on the first back plate 53, and the periphery of the movable rod of the second linear module 510 is located within the second sliding hole. A first spring 511 is provided around the movable rod of the second linear module 510, and the two ends of the first spring 511 are respectively fixedly connected to one end of the movable rod of the second linear module 510 and the first connecting plate 59. The cutting motor 56 can drive... The rotating slice 55 is used to cut the linear steel pipe. Cutting the steel pipe with the slice 55 reduces the cutting pressure on the outer surface of the steel pipe, preventing the steel pipe end face from deforming due to excessive pressure. The second linear module 510 is a linear motor or cylinder of the prior art. The second linear module 510 can push the first slide plate 57, the first connecting plate 59 and the slice 55 closer to or away from the linear steel plate to meet the cutting requirements. The first spring 511 is a floating elastic structure of the cutting motor 56 and the slice 55, which prevents the second linear module 510 from forcibly squeezing the slice 55 onto the surface of the steel pipe and causing damage to the slice 55, thereby improving the service life of the parts. At the same time, the first spring 511 can provide a clamping force for the slice 55 to contact the surface of the steel pipe.

[0036] After the steel pipe is cut by the slicing blade 55, cutting chips and sharp, adhered nicks will remain on the outer edge of the steel pipe. These chips and nicks need to be removed to prevent scratches to subsequent equipment or harm to workers. A trimming assembly is also installed on the first back plate 53. This assembly includes a second sliding plate 512, one side of which is slidably connected to a second slide rail, which is fixedly mounted on the first back plate 53. A second connecting plate is provided on the second sliding plate 512, and a third sliding hole is provided on the second connecting plate. A third linear module is installed on the first back plate 53. The third linear module is... In existing linear motors or push rod cylinders, the periphery of the movable rod of the third linear module is located inside the third sliding hole, and a second spring is provided on the periphery of the movable rod of the third linear module. The two ends of the second spring are respectively fixedly connected to one end of the movable rod of the third linear module and the second connecting plate. A trimming head 513 is provided on the other side of the second sliding plate 512. One end of the trimming head 513 can abut against the sawing gap of the linear steel pipe. When the first back plate 53 rotates relative to the steel pipe, the trimming head 513 can simultaneously remove the cutting chips and sticky sharp edges in the sawing gap as the steel pipe is sawed. The removal is rigid, and the trimming quality is controllable.

[0037] The trimming head 513 is connected to the first back plate 53 via an adjusting assembly. The adjusting assembly includes an adjusting block 514 with a through hole. One end of an adjusting bolt 515 passes through the through hole and is threaded onto the second slide plate 512. A third spring 516 is provided around the adjusting bolt 515. The two ends of the third spring 516 are respectively fixedly connected to the second slide plate 512 and the adjusting block 514. A fourth sliding hole is provided on the adjusting block 514, and a slide seat 517 is slidably connected within the fourth sliding hole. The trimming head 513 is installed at one end of the slide seat 517, and the other end of the slide seat 517 is rotatably sleeved onto one end of an adjusting rod 518. The outer periphery of the adjusting rod 518 is threaded onto an end cap, and the end cap is fixedly connected to the adjusting block 514. 4. By turning the adjusting bolt 515, the distance between the adjusting block 514 and the second slide plate 512 can be released. The third spring 516 causes the adjusting block 514 to move away from the second slide plate 512, thereby realizing the axial movement of the trimming head 513 relative to the linear steel pipe. This makes it easy for the operator to adjust the position of the trimming head 513 relative to the sawing gap so as to accommodate slices 55 of different thicknesses. The third linear module is used to drive the adjusting component and the trimming head 513 closer to or away from the outer periphery of the steel pipe so as to bring the trimming head 513 into the working position and away from the working position. By turning the adjusting rod 518, the trimming head 513 can be moved closer to or away from the outer periphery of the steel pipe, which facilitates the fine adjustment of the working position of the trimming head 513 to meet production requirements.

[0038] The detection assembly 3 includes a second sleeve 31, one end of which is rotatably sleeved onto one side of a support frame 4. A second gear 32 is fixedly installed on the support frame 4, with the inner ring of the second gear 32 located around the second sleeve 31.

A second rotary motor 34 is fixedly installed on one side of the second back plate 33, with the outer periphery of the transmission gear of the second rotary motor 34 meshing with the outer periphery of the second gear 32. Two detection units are installed on the other side of the second back plate 33, facing each other. The outer periphery of the linear steel pipe is located between the two detection units. The second sleeve 31 and the second back plate 33 rotate in the same manner as the first sleeve 51 and the first back plate 53, thereby driving the two detection units to rotate relative to the outer periphery of the steel pipe. The execution ends of the two detection units respectively abut against the outer periphery of the steel pipe. By measuring the fluctuation of the distance between the two execution ends, the consistency of the outer diameter of the steel pipe and whether the steel pipe is bent are detected, so as to record the product quality data of each sawn segment, improve detection efficiency, and ensure product quality.

[0039] Each detection unit is fixedly mounted on a third slide plate 35, and one side of the third slide plate 35 is slidably connected to the periphery of a third slide rail. The third slide rail is fixedly mounted on a second back plate 33. A third connecting plate 36 is mounted on the third slide plate 35. One end of the third connecting plate 36 is detachably mounted to the movable end of a fourth linear module 37, and the fourth linear module 37 is fixedly mounted on the second back plate 33. The fourth linear module 37 is a linear motor or cylinder of the prior art. The fourth linear module 37 is used to drive the detection unit closer to or away from the steel pipe in order to meet the detection of different product specifications and improve the versatility of the equipment.

[0040] The detection unit includes a housing 38, which is fixedly mounted on a third sliding plate 35. A fifth sliding hole is provided in the middle of the housing 38, and a sliding sleeve 39 and a top cover 310 are respectively provided at both ends of the fifth sliding hole. A top rod 311 is slidably connected to the middle of the sliding sleeve 39. A ball bearing 312 is provided at one end of the top rod 311, and the other end of the top rod 311 is elastically connected to the top cover 310 via a fourth spring 313. A grating ruler is provided on the top rod 311. A retaining ring 314 is fitted around the top rod 311, and the retaining ring 314 is slidably connected to the fifth sliding hole. One end of the retaining ring 314 can abut against one end of the sliding sleeve 39. The ball bearing 312 is slidably connected to the outer periphery of the steel pipe, reducing the friction between the ball bearing 312 and the steel pipe. The four springs 313 form a floating structure for the ball bearings 312 and the push rod 311. This prevents the outer periphery of the steel pipe from being forced against the ball bearings 312 when the pipe diameter changes. The retaining ring 314 limits the outward protrusion of the ball bearings 312, preventing the push rod 311 and the ball bearings 312 from sliding out of the fifth sliding hole. A grating ruler is installed on the push rod 311, and a photoelectric probe is installed in the fifth sliding hole. When the push rod 311 slides due to the change in the outer diameter of the steel pipe, the grating ruler can measure the floating amount of the push rod 311. During the movement of the steel pipe relative to the detection unit, the distance between the execution ends of the two opposing detection units can measure the change in the outer diameter of the steel pipe. The floating amount of each detection unit can determine whether the steel pipe needs to be straightened.

[0041] If the top rods 311 of the two detection units slide towards each other, it means that the outer diameter of the steel pipe has increased; if the two detection units slide relative to each other, it means that the outer diameter of the steel pipe has decreased; if the two top rods 311 slide in the same direction, it means that straightening is required; if one top rod 311 does not slide and the other top rod 311 slides relative to each other, it means that rounding is required or there is a structural defect. The specific sliding tolerance of the top rod 311 depends on the actual working conditions, which will not be elaborated here. In order to prevent the grating ruler signal line from getting tangled when the second back plate 33 rotates relative to each other, a conductive slip ring of the prior art is set on the periphery of the connection between the second sleeve 31 and the support frame 4.

[0042] like Figure 1As shown, the lower end of the floating base 1 is equipped with multiple wheel frames along the travel direction. Each wheel frame is equipped with a first central shaft 11, and the two ends of the first central shaft 11 are respectively rotatably sleeved with wheel bodies 12. The outer periphery of each wheel body 12 is tactilely connected to the outer periphery of the guide rail 13. The outer periphery of each wheel body 12 is provided with a first concave annular groove, and the outer periphery of the guide rail 13 is tactilely connected to the first concave annular groove. One side of the floating base 1 is connected to the movable end of the first linear module, and the first linear module is fixedly installed on the foundation. The first linear module is used to drive the floating base 1 to move on the guide rail 13. The first linear module is a push rod cylinder of the prior art. The linear steel pipe is sequentially input from the previous process to the support component 2, the detection component 3, the sawing component 5, and the... The clamping component 6 is used to hold the steel pipe tightly when sawing it. The steel pipe and the sawing component 5 are relatively stationary. The clamping component 6 is used to hold the steel pipe tightly. When the clamping component 6 holds the steel pipe tightly, the air inlet of the first linear module is connected to the outside atmosphere. The linear steel pipe can push the floating base 1 forward. At this time, the sawing component 5 is stationary relative to the steel pipe so as to cut the steel pipe. After the cutting is completed, the clamping component 6 no longer holds the steel pipe, the air inlet of the first linear module is closed, and the external air pump draws a vacuum to make the movable end retract, pulling the floating base 1 to reset so as to continue working. In order to improve the pulling action of the first linear module, a hydraulic cylinder of the existing technology can also be used, and its working mode is the same as that of the push rod cylinder mentioned above.

[0043] The support assembly 2 includes a first support plate 21. The two ends of the first support plate 21 are respectively provided with a first sliding hole and a first threaded hole. A first sliding rod 22 is slidably connected in the first sliding hole, and a first lead screw 23 is threadedly connected in the first threaded hole. The first sliding rod 22 and the first lead screw 23 are respectively sleeved on the first frame 24. The first frame 24 is fixedly installed on the upper end of the floating base 1. A support roller 25 is rotatably arranged on the first support plate 21. The support roller 25 is used to support the periphery of the linear steel pipe. When the operator rotates the first lead screw 23, the first support plate 21 can be raised and lowered. The relative trajectory of the first support plate 21 can be limited by the first sliding rod 22. The support roller 25 supports the linear steel pipe to prevent the steel pipe from falling due to gravity, so as to ensure that the steel pipe is concentric with the detection unit and the sawing assembly 5.

[0044] In implementation, a second concave annular groove is provided around the support roller 25. The outer periphery of the linear steel pipe is rolled into the second concave annular groove to limit the relative position of the outer periphery of the steel pipe. The concave annular groove can meet the needs of steel pipes with different outer diameters, improving the versatility of the device. One end of the support roller 25 is connected to an encoder, which is existing technology. The encoder is used to detect the number of rotations of the support roller 25. The number of rotations of the support roller 25 can be used to calculate the path of the steel pipe through the support roller 25, so as to start the clamping assembly 6 and the sawing assembly 5.

[0045] The clamping assembly 6 includes a second frame 61, which is fixedly mounted on the floating base 1. Two clamping units are mounted on the second frame 61 and face each other. Each clamping unit includes a slide 62, which is slidably connected to the periphery of a platform 63. A second lead screw is rotatably sleeved on the platform 63. The slide 62 is threadedly connected to the periphery of the second lead screw. A clamping motor 64 is mounted at one end of the second lead screw. A fifth linear module 65 is mounted on one side of the slide 62, and a gripper 66 is mounted on the movable end of the fifth linear module 65. The cross-section of the gripper 66 is V-shaped or arc-shaped. One side of the gripper 66 can abut against the outer periphery of the linear steel pipe. In this embodiment, the gripper 66 is V-shaped. The slide table 62 slides on the frame 63 to adjust the relative height of the gripper 66. The fifth linear module 65 is a linear motor or push rod cylinder of the prior art. The fifth linear module 65 is used to drive the gripper 66 to move closer to or away from the outer periphery of the steel pipe. The two opposing grippers 66 can hold the outer periphery of the steel pipe tightly to prevent the steel pipe from moving relative to the sawing component 5 when sawing the steel pipe.

[0046] The conveying assembly 7 includes a third frame 71, on which multiple support rods 72 are mounted, and the support rods 72 are arranged parallel to each other. The upper end of each support rod 72 is fixedly connected to an upper plate 73, and a third lead screw 74 is threadedly connected to the middle of the upper plate 73. The lower end of the third lead screw 74 is rotatably sleeved to a lower pressure plate 75. A lower pressure roller 76 is rotatably sleeved on the lower pressure plate 75. An upper pressure plate 77 is located below the lower pressure plate 75, and an upper pressure roller 78 is rotatably sleeved on the upper pressure plate 77. The lower pressure roller 76 and the upper pressure roller 78 are arranged parallel to each other. The linear steel pipe is located on the upper pressure roller 76. Between the upper pressure roller 78 and the lower pressure roller 76, and the outer periphery of the linear steel pipe is respectively rolled to the outer periphery of the upper pressure roller 78 and the lower pressure roller 76. One end of the upper pressure roller 78 is fixedly connected to the drive shaft of the conveyor motor 711, and the conveyor motor 711 is fixedly installed on the upper pressure plate 77. The conveyor motor 711 can drive the upper pressure roller 78 to rotate, and through differential rotation, it drives the cut steel pipe to quickly leave the floating base 1 and be transferred to the next process. The third screw 74 can adjust the relative height of the lower pressure plate 75 so that the lower pressure roller 76 can meet the usage requirements of steel pipes with different outer diameters.

[0047] The upper pressure plate 77 is provided with multiple limiting sliding holes, and a support rod 72 is slidably connected in each limiting sliding hole. A fifth spring 79 is provided around each support rod 72. The two ends of the fifth spring 79 are fixedly connected to the upper side of the third frame 71 and the lower side of the upper pressure plate 77, respectively. The fifth spring 79 is used to drive the upper pressure plate 77 to move upward, so that the outer periphery of the upper pressure roller 78 is always in contact with the outer periphery of the steel pipe. This meets the needs of steel pipes with different outer diameters while ensuring that the upper pressure roller 78 drives the steel pipe to move. A sixth straight... Line module 710, the movable end of the sixth linear module 710 is fixedly connected to the upper pressure plate 77. The sixth linear module 710 is a push rod cylinder of the prior art. The sixth linear module 710 can drive the upper pressure plate 77 away from the lower pressure plate 75. When the steel pipe is not being cut, it ensures that the upper pressure roller 78 does not contact the outer periphery of the steel pipe. After the steel pipe is cut, the sixth linear module 710 is in an idle rotation state. Its movable rod can move upward elastically with the fifth spring 79. The sixth linear module 710 does not interfere with the upper pressure roller 78 approaching the lower pressure roller 76.

[0048] The control method in this embodiment is controlled by a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. This document is mainly used to protect mechanical devices. The control method and circuit connection will not be explained in detail here. The signals of the encoder and the grating ruler are transmitted to the controller.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
