[0051] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field to which the present invention belongs; the terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention; the term "and / or" used herein includes any and all combinations of one or more related listed items.

[0052] Embodiment 1: Figures 1 to 9 As shown, the equipment for steel pipe cutting of the present application includes an operating table 10, a cutting mechanism 30, a feeding mechanism 40, two clamping mechanisms 20, two abutting softwares 50, a power assembly and a control unit.

[0053] The two clamping mechanisms 20 are arranged opposite to each other on the operating table 10 , and the clamping mechanisms 20 include side clamping plates 21 and a first driving component 22 .

[0054] The bottom ends of the side clamping plates 21 are hinged on the operating table 10 , and the sides of the two side clamping plates 21 that are away from each other are hinged to the top ends of the first driving components 22 .

[0055] The bottom end of the first driving component 22 is hinged on the operating table 10 , and the first driving component 22 can drive the tops of the two side clamping plates 21 to move away from or closer to each other.

[0056] It should be noted that the first driving component 22 is an automatic telescopic structure, for example, the first driving component 22 can be a telescopic cylinder.

[0057] It should be noted that when the first driving component 22 is extended to the maximum length, the tops of the two side clamping plates 21 are in contact with each other, and the two side clamping plates 21 can form an angle.

[0058] The cutting mechanism 30 and the feeding mechanism 40 are both disposed on the operating table 10 , and the cutting mechanism 30 and the feeding mechanism 40 are respectively located on both sides of the clamping mechanism 20 .

[0059] The cutting mechanism 30 includes a bracket 31 , a second driving component 32 , a mounting seat 33 and a cutting blade 34 .

[0060] The bracket 31 is installed on the operating table 10 .

[0061] The top of the second driving component 32 is connected to the bracket 31 , and the bottom of the second driving component 32 is connected to the mounting seat 33 .

[0062] It should be noted that the second driving component 32 is an automatic telescopic structure along the vertical direction. For example, the second driving component 32 can be a telescopic cylinder.

[0063] The cutting blade 34 is mounted on the mounting seat 33 .

[0064] Preferably, a cutting groove 11 is formed on the operating table 10 , and the cutting groove 11 is located below the cutting knife 34 .

[0065] The feeding mechanism 40 includes an electric slide rail 41 and a pushing block 42 .

[0066] The electric slide rail 41 is installed on the operating table 10 , and the electric slide rail 41 is located between the two side clamping plates 21 .

[0067] The top of the electric slide rail 41 and the top surface of the operating table 10 are located on the same plane.

[0068] One end of the electric slide rail 41 extends to the cutting groove 11 , and the other end of the electric slide rail 41 extends out of the operating table 10 . The pushing block 42 is slidably disposed on the electric slide rail 41 .

[0069] It should be noted that the pushing block 42 is located on the top surface of the electric slide rail 41, and the seamless steel pipe 60 can be placed on the electric slide rail 41. The pushing block 42 can be controlled to slide by the electric slide rail 41, thereby pushing the seamless steel pipe 60 to move. The cooperation method between the electric slide rail 41 and the pushing block 42 is the existing technology and will not be repeated here.

[0070] The two abutting soft bodies 50 are respectively disposed on the surfaces of the two side clamping plates 21 close to each other, and the material of the abutting soft bodies 50 is rubber.

[0071] It should be noted that the interference soft body 50 in this example can be in the shape of a long strip corresponding to the side clamping plate 21, and the length of the interference soft body 50 is selected according to actual needs, which will not be described in detail here.

[0072] It can be understood that when the seamless steel pipe 60 is placed between the two side clamping plates 21, the first driving component 22 controls the two side clamping plates 21 to move closer to each other, thereby clamping the seamless steel pipe 60.

[0073] The power assembly is used to provide energy for the operation of the equipment, preferably an AC power supply or a battery; the control unit is used to control the coordinated operation of various components of the equipment, preferably a programmable logic controller; all of which are prior arts and will not be described in detail here.

[0074] When the device for cutting steel pipes in the embodiment of the present application is actually operated, the steps are as follows:

[0075] S1: placing the seamless steel pipe 60 on the electric slide rail 41, ensuring that the seamless steel pipe 60 is located between the two side clamping plates 21;

[0076] S2: The control unit controls the first driving component 22 to work, so that the tops of the two side clamping plates 21 are close to each other until the seamless steel pipe 60 is clamped;

[0077] S3: Control the electric slide rail 41 to work, and the push block 42 slides on the electric slide rail 41, driving the seamless steel pipe 60 to move to a predetermined position in the direction of the cutting knife 34;

[0078] S4: The control unit controls the second driving component 32 to operate, so that the cutting knife 34 descends to cut the seamless steel pipe 60;

[0079] S5: After the cutting is completed, the cutting knife 34 rises and resets, and the first driving component 22 is controlled to work, so that the tops of the two side clamping plates 21 are separated from each other, and the seamless steel pipe 60 is released. If necessary, the above steps can be repeated for multiple cuttings.

[0080] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0081] 1. The side clamping plate 21 automates the clamping, feeding and cutting process, significantly improving the efficiency of steel pipe cutting. At the same time, it can adapt to seamless steel pipes 60 of various shapes and thicknesses, and adapt to more scenarios;

[0082] 2. The rubber-made resistance soft body 50 effectively protects the surface of the seamless steel pipe 60 from being scratched, thereby improving product quality.

[0083] Embodiment 2: In the above embodiment, the interference soft body 50 is an integral structure. Deformation of one end of the interference soft body 50 may affect the clamping effect of other parts, and the overall setting of the interference soft body 50 is difficult to stably clamp the uneven seamless steel pipe 60 (for example, the wavy seamless steel pipe 60); the embodiment of the present application is optimized on the basis of the above embodiment.

[0084] like Figure 4 and Figure 5 As shown, the interference software 50 in this embodiment includes a plurality of first softwares 51 and a plurality of second softwares 52 , and the first softwares 51 and the second softwares 52 are alternately arranged on the corresponding side clamping plates 21 in sequence.

[0085] It should be noted that the multiple first software 51 can be 3, 4, 5, 6, 7 first software 51, etc., and the multiple second software 52 can be 3, 4, 5, 6, 7 second software 52, etc. The specific number of the first software 51 and the second software 52 is selected according to actual needs and will not be described in detail here.

[0086] The adjacent first software 51 and second software 52 are arranged at intervals.

[0087] It should be noted that, in this embodiment, the first soft body 51 and the second soft body 52 have smooth convex surfaces on their surfaces away from the corresponding side clamping plates 21 .

[0088] It should be noted that the interval between the adjacent first software 51 and the second software 52 is selected according to actual needs and will not be described in detail here.

[0089] The elastic coefficient of the second soft body 52 is smaller than the elastic coefficient of the first soft body 51 .

[0090] It should be noted that the elastic coefficient of the second software 52 and the elastic coefficient of the first software 51 are selected according to actual needs and will not be described in detail here.

[0091] It can be understood that when the seamless steel pipe 60 is placed between the two side clamps 21, multiple first soft bodies 51 and multiple second soft bodies 52 are staggered in sequence to contact the surface of the seamless steel pipe 60, thereby increasing the contact area and contact points with the seamless steel pipe 60, and the friction between the resisting soft bodies 50 and the seamless steel pipe 60 is relatively large, thereby improving the stability and reliability of clamping; since the elastic coefficients of the first soft bodies 51 and the second soft bodies 52 are different, they can be deformed according to different clamping requirements to better adapt to the shape and size of the steel pipe; during the clamping process, the first soft body 51 provides the main clamping force to ensure that the seamless steel pipe 60 is stable and motionless; and the second soft body 52, through its lower elastic coefficient and smooth convex surface, can better adapt to the tiny bumps on the surface of the seamless steel pipe 60, thereby improving the fit and protection effect of the clamping.

[0092] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0093] 1. Multiple first soft bodies 51 and second soft bodies 52 are arranged alternately, which can stably clamp the uneven or irregularly shaped seamless steel pipe 60, thereby improving the stability and reliability of the clamping. The stable clamping effect helps to reduce the shaking and deviation of the seamless steel pipe 60 during the cutting process, thereby improving the cutting accuracy and consistency;

[0094] 2. The lower elastic coefficient and the smooth convex surface setting of the second soft body 52 effectively reduce the indentation and scratches on the surface of the seamless steel pipe 60, and protect the surface quality of the seamless steel pipe 60;

[0095] 3. Increase the friction between the resisting soft body 50 and the seamless steel pipe 60, and further reduce the shaking and deviation of the seamless steel pipe 60 during the cutting process.

[0096] Embodiment 3: In the above embodiment, left and right deviations may occur during the movement of the seamless steel pipe 60, which reduces the accuracy and consistency of subsequent cutting; the embodiment of the present application is optimized to a certain extent on the basis of the above embodiment.

[0097] like Figure 5 As shown, a first pressure sensor 512 is disposed inside the first software 51 .

[0098] A rubber ball 511 is movably embedded in the first soft body 51 , and the rubber ball 511 can contact the seamless steel pipe 60 .

[0099] The material of the rubber ball 511 is rubber, and the elastic coefficient of the rubber ball 511 is smaller than the elastic coefficient of the first soft body 51 .

[0100] It should be noted that the matching method of the rubber ball 511 and the first soft body 51 can refer to the setting method of the bull's eye wheel, which will not be described in detail here.

[0101] It can be understood that when the seamless steel pipe 60 is clamped between the two side clamps 21, as the first driving component 22 is driven, the first soft body 51 gradually approaches the steel pipe and applies a clamping force through the rubber ball 511. The control unit adjusts the working state of the first driving component 22 according to the received pressure data to ensure that the clamping force is always maintained within an appropriate range. At this time, the rubber ball 511 is in a locked state; since the elastic coefficient of the rubber ball 511 is small, it can better adapt to the shape of the surface of the seamless steel pipe 60 to ensure the fit of the clamping; when the seamless steel pipe 60 needs to move, the first driving component 22 controls the resistance between the rubber ball 511 and the seamless steel pipe 60, so that the rubber ball 511 can rotate, thereby assisting the seamless steel pipe 60 to move.

[0102] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0103] 1. Through real-time monitoring and feedback of the first pressure sensor 512, the clamping force can be accurately controlled to prevent damage to the seamless steel pipe 60 or cutting deviation caused by clamping too tight or too loose;

[0104] 2. The introduction of the rubber ball 511 increases the adaptability of the clamping, so that the equipment can better adapt to seamless steel pipes 60 of different shapes and sizes;

[0105] 3. The combination of the rubber ball 511 and the first soft body 51 effectively reduces the indentations and scratches on the surface of the seamless steel pipe 60, thereby protecting the surface quality of the seamless steel pipe 60;

[0106] 4. The seamless steel pipe 60 is assisted in moving by a plurality of rubber balls 511, so that the seamless steel pipe 60 is unlikely to deviate left or right during the movement, thereby ensuring the accuracy and consistency of subsequent cutting.

[0107] Embodiment 4: In the above embodiments, it is possible that the contact area between the first soft body 51 and the second soft body 52 and the seamless steel pipe 60 is small. In this case, the friction between the interfering soft body 50 and the seamless steel pipe 60 is small, which may cause the seamless steel pipe 60 to rotate to a certain extent, affecting the cutting accuracy. The embodiments of the present application are optimized based on the above embodiments.

[0108] like Figure 8 As shown, the second soft body 52 is hollow inside and filled with an inner medium 53 .

[0109] The inner medium 53 is a fluid.

[0110] The inner medium 53 may be gas, water or a non-Newtonian fluid.

[0111] It should be noted that, in this embodiment, the volume of the inner medium 53 and the pressure inside the second software 52 are selected according to actual needs and will not be elaborated here.

[0112] Further, such as Figures 6 to 8 As shown, two storage boxes 70 are disposed on the operating table 10 , and the storage boxes 70 correspond to the conflicting software 50 one by one.

[0113] A pumping assembly 71 is installed inside the storage box 70 . The input end of the pumping assembly 71 extends to the bottom of the storage box 70 , and the output end of the pumping assembly 71 is connected to a hose 72 .

[0114] The storage box 70 stores the inner medium 53 .

[0115] The pumping component 71 may be a fluid pump.

[0116] The side clamping plate 21 is hollow inside, and the internal space of the side clamping plate 21 is a communication cavity 211 , and a second pressure sensor 212 is disposed in the communication cavity 211 .

[0117] The communication cavity 211 is communicated with the interiors of all the second soft bodies 52 disposed on the corresponding side clamping plates 21 .

[0118] One end of the hose 72 away from the pumping assembly 71 is in communication with the corresponding communication cavity 211 , so that the volume of the internal medium 53 inside the second software 52 can be controlled by the pumping assembly 71 .

[0119] It can be understood that the pumping component 71 extracts the internal medium 53 from the storage box 70, transports it to the connecting cavity 211 of the side clamp 21 through the hose 72, and then enters the interior of the second soft body 52; by controlling the working state of the pumping component 71 (such as pumping speed, working time, etc.), the volume of the internal medium 53 inside the second soft body 52 can be adjusted, thereby changing its hardness and supporting force, and at the same time changing the contact area between the second soft body 52 and the seamless steel pipe 60; at the same time, the second pressure sensor 212 can monitor the pressure changes in the connecting cavity 211 in real time, and provide feedback signals for the control system; according to actual needs and changes in the working environment, the working state of the pumping component 71 can be adjusted in real time, so that the second software 52 can quickly adapt and maintain the best support effect.

[0120] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0121] 1. By dynamically adjusting the volume and pressure of the inner medium 53, the second software 52 can adapt to seamless steel pipes 60 of different shapes, sizes and weights, thereby improving the adaptability and flexibility of the equipment;

[0122] 2. The setting of the inner medium 53 provides a stable supporting force for the second soft body 52, enhances its bearing capacity and stability, and enables the second soft body 52 to fit the seamless steel pipe 60 more closely;

[0123] 3. Through the coordinated use of the pumping assembly 71 and the second pressure sensor 212, the volume and pressure of the internal medium 53 are automatically adjusted and controlled, thereby improving the automation level and intelligence of the equipment;

[0124] 4. By controlling the internal pressure and volume of the second soft body 52, the contact area and the resistance between the second soft body 52 and the seamless steel pipe 60 are controlled, thereby adjusting the clamping effect of the seamless steel pipe 60, which is more flexible to use;

[0125] 5. The inner medium 53 can be used to provide pressure support, shock absorption or serve as a medium for energy transfer.

[0126] Embodiment 5: If the surface flatness of the seamless steel pipe 60 in the above embodiment is too low, it may cause the second soft body 52 and the seamless steel pipe 60 to have a low fit. The embodiment of the present application is optimized to a certain extent on the basis of the above embodiment.

[0127] like Fig. 9 As shown, a diaphragm 521 is disposed inside the second soft body 52 , and the diaphragm 521 divides the internal space of the second soft body 52 into chamber one and chamber two, wherein chamber one is located on the side of chamber two away from the seamless steel pipe 60 .

[0128] The inner medium 53 in this embodiment is filled in the chamber one, and the communication cavity 211 is communicated with the chamber one.

[0129] The second chamber is a closed space, and the interior of the second chamber is filled with magnetic fluid 522 .

[0130] It can be understood that the magnetic fluid 522 enables the second soft body 52 to have a certain magnetism while maintaining flexibility. This magnetism can be used to adsorb the seamless steel pipe 60 with ferromagnetic properties. At the same time, the magnetic fluid 522 in the two relatively conflicting soft bodies 50 can also be magnetically attracted to each other. Even for the seamless steel pipe 60 that does not have ferromagnetic properties, it can play a better coating effect and improve the stability and accuracy of clamping. In addition, in some application scenarios, the second soft body 52 can also be remotely controlled or positioned by applying an external magnetic field to achieve a higher level of automation and intelligent control.

[0131] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0132] By providing the magnetic fluid 522, the second soft body 52 can better fit with the seamless steel pipe 60, further improving the stability and accuracy of clamping.

[0133] In summary, the equipment for steel pipe cutting of the present application can be flexibly adjusted to adapt to steel pipes of different diameters, improves the cutting accuracy on steel pipes of different shapes, and increases the technical effect of the scope of application.

[0134] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
