[0026] It also includes a horizontal plate 37, a top plate 38, an electric actuator V39 and a limit block 310; all the baffles 36 are slidably connected to a horizontal plate 37; the horizontal plate 37 is slidably connected to a top plate 38; the horizontal plate 37 is fixedly connected to an electric actuator V39, which is an electric push rod, and the telescopic part of the electric actuator V39 is fixedly connected to the top plate 38; the top plate 38 is fixedly connected to the limit block 310 at one end away from the electric actuator V39.

[0027] The limit block 310 is made of rubber, and a plurality of arc grooves are provided on the side of the limit block 310 away from the top plate 38 to increase the contact area between the limit block 310 and the seamless steel pipe 3 and increase the friction between the limit block 310 and the seamless steel pipe 3.

[0028] The following will be discussed by taking the cutting of three seamless steel pipes 3 at the same time as an example. The external pump for conveying cutting fluid is connected to the liquid guide pipe 13 in advance, and then the seamless steel pipes 3 are placed on the fixed plate Ⅰ33 one by one, and the seamless steel pipes 3 are supported by the fixed plate Ⅰ33. Then, the two electric sliders Ⅱ35 are controlled to start moving toward each other along the electric slide rail Ⅱ34. Each electric slider Ⅱ35 moves and drives a baffle 36 to move, and then the seamless steel pipe 3 is clamped and limited by the two baffles 36. Then, the two electric sliders Ⅰ32 are controlled to start moving along the electric slide rail Ⅱ34. The corresponding electric slide rail Ⅰ31 moves to the right based on the front side of the chassis 2, and the two electric sliders Ⅰ32 move to drive the fixed plate Ⅰ33 to move. The fixed plate Ⅰ33 moves to drive all the connected parts to move, and then drives all the seamless steel pipes 3 clamped and limited by the two baffles 36 to move to the right, until the right end of the seamless steel pipe 3 moves to the cutting machine 1, and then controls the electric actuator Ⅲ202 to start and drive the mounting plate 203 to move downward. The mounting plate 203 moves to drive the two round rods 204 to move. The two round rods 204 move to drive the grid plate Ⅰ205 to move downward, thereby compressing the two The elastic member 206 causes the grid plate I 205 to press against all the seamless steel pipes 3, thereby limiting all the seamless steel pipes 3, and then controlling the two electric actuators IV 207 to start and drive each grid plate II 2071 to move, so that the two grid plates II 2071 move toward each other, thereby making the two contact with the corresponding seamless steel pipes 3 and limiting the seamless steel pipes 3, thereby clamping and limiting the seamless steel pipes 3 through the cooperation of the grid plates I 205 and the grid plates II 2071, and then controlling the electric actuator V 39 to start and drive the top plate 38 to move downward, and the top plate 38 moves to drive the limiting The positioning block 310 moves until the limiting block 310 abuts against the seamless steel pipe 3, and then the seamless steel pipe 3 is limited by the limiting block 310, and then the cutting machine 1 is controlled to start operating to cut the seamless steel pipe 3. While cutting, the external pump is controlled to start operating to transport cutting fluid into the liquid guide tube 13, and the cutting fluid is sprayed onto the saw blade in the cutting machine 1 through the liquid guide tube 13, thereby reducing the temperature of the saw blade and the seamless steel pipe 3 in the cutting machine 1, and removing metal chips generated during the cutting process, and then collecting the cut seamless steel pipe 3, thereby completing the cutting operation of the seamless steel pipe 3.

[0029] It should be noted that when cutting to the end of the seamless steel pipe 3, the length of the seamless steel pipe 3 is shortened, and then the linear drive 44 is controlled to start and drive the rectangular frame 45 to move upward, so that the rectangular frame 45 is flush with the height of the seamless steel pipe 3, and the rectangular frame 45 is flush with the center position of the seamless steel pipe 3, so that the rectangular frame 45 can simultaneously resist the left ends of all seamless steel pipes 3 to be cut, and then the two electric sliders III 42 are controlled to move to the right along an electric slide rail III 41. The movement of the two electric sliders III 42 jointly drives the crossbeam 43 to move, and the movement of the crossbeam 43 drives the linear drive 44 to move, and the movement of the linear drive 44 drives the rectangular frame 45 to move, so that the rectangular frame 45 resists the left ends of all seamless steel pipes 3 to be cut, and pushes the seamless steel pipe 3 to move to the right, and the rectangular frame 45 can pass between the grid plate I 205 and the grid plate II 2071, thereby realizing the transmission of the end of the seamless steel pipe 3 to the cutting machine 1, and then the end of the seamless steel pipe 3 is cut by the cutting machine 1.

[0030] However, since the seamless steel pipe 3 is easily impacted during transportation and placement, the seamless steel pipe 3 is prone to bending and deformation. In the prior art, the seamless steel pipe 3 is not inspected and screened when it is cut. As a result, when three seamless steel pipes 3 are cut at the same time, the cut seamless steel pipes 3 are prone to inconsistent lengths and uneven cuts, which affects the subsequent use of the seamless steel pipe 3. In order to solve the above problem, before cutting the seamless steel pipe 3, the seamless steel pipe 3 is placed on the fixed plate I33, and the right part of the seamless steel pipe 3 is located between the two grid plates II2071, and the grid plates I205 and II2071 do not clamp and limit the right part of the seamless steel pipe 3, and the left part of the seamless steel pipe 3 is located between the two electric conveyor belts 211, as shown in FIG. Figure 1 As shown, the electric actuator III 202 is then controlled in the same manner as above to start driving the mounting plate 203 to move downward, thereby driving all connected components to move, thereby causing the grid plate I 205 to move downward to press against all seamless steel pipes 3, and compressing the two elastic members 206, thereby squeezing the right part of the seamless steel pipe 3, and all elastic members 206 have a margin and are not compressed to the limit, so that the seamless steel pipe 3 can still rotate when limited by the grid plate I 205, so as to facilitate the inspection of the seamless steel pipe 3 and pick out the bent and deformed seamless steel pipe 3.

[0031] Next, all the electric actuators I 209 are controlled to start and drive the corresponding sliding frame 210 to move, so that every two sliding frames 210 move and drive the corresponding electric conveyor belt 211 to move, so that the two electric conveyor belts 211 move toward each other and contact with the seamless steel pipe 3, and then the two electric conveyor belts 211 are controlled to start operation, and the movement directions of the conveyor belts in the two electric conveyor belts 211 are opposite, and then the seamless steel pipe 3 is rotated by the movement of the conveyor belts in the two electric conveyor belts 211, and then the two electric actuators II 212 are controlled to start and drive the fixed plate II 213 to move downward, and the movement of the fixed plate II 213 drives the visual detector 214 to move, so that the visual detector 214 moves to the seamless steel pipe 3 The center positions are aligned, and the rotation trajectory of the seamless steel pipe 3 is recorded and detected by the visual detector 214. If the seamless steel pipe 3 has radial circular runout during the rotation, it means that the seamless steel pipe 3 has bent and deformed, and it is determined that the seamless steel pipe 3 does not meet the production standards, and the seamless steel pipe 3 is discarded. If the visual detector 214 does not detect radial circular runout of the seamless steel pipe 3 during the rotation, it means that the seamless steel pipe 3 has not bent and deformed, and meets the production standards, and then the seamless steel pipe 3 is cut, so that the seamless steel pipe 3 can be inspected and screened before the cutting operation, so as to avoid the inconsistent length and uneven incision of the seamless steel pipe 3 after cutting, thereby improving the quality of the seamless steel pipe 3.

[0032] It should be noted that in order to ensure that the two electric conveyor belts 211 can drive the seamless steel pipe 3 to rotate during operation, all electric actuators I209 are controlled in the same way as above to start and drive the corresponding sliding frame 210 to move, so that the two electric conveyor belts 211 move toward each other and squeeze the seamless steel pipe 3, thereby increasing the friction between the electric conveyor belts 211 and the seamless steel pipe 3, thereby ensuring that the two electric conveyor belts 211 can drive the seamless steel pipe 3 to rotate during operation.

[0033] Moreover, when any one of the three seamless steel pipes 3 has radial runout during rotation, the seamless steel pipe 3 with radial runout is removed, and the other two seamless steel pipes 3 continue to be rotated and tested until all the seamless steel pipes 3 to be cut are tested and qualified, and then the cutting operation is carried out, thereby ensuring that all the seamless steel pipes 3 to be cut are qualified, and further ensuring that the lengths of all the seamless steel pipes 3 after cutting are consistent and the incisions are flat.

[0034] Example 2: Based on Example 1, Figure 1 and Figure 7-Figure 9As shown, it also includes a dust removal system; the dust removal system is connected to the base frame 2; the dust removal system includes a fixed plate III 301, an electric actuator VI 302, a fixed frame 303, a motor 304 and a guide wheel 305; two fixed plates III 301 are fixed to the base frame 2; each fixed plate III 301 is fixed with an electric actuator VI 302, and the electric actuator VI 302 is an electric push rod; the telescopic part of each electric actuator VI 302 is fixed with a fixed frame 303; each fixed frame 303 is mounted with a motor 304; the output shaft of each motor 304 is fixed with a guide wheel 305.

[0035] The guide wheel 305 is provided with an arc-shaped portion 3051 , and the arc-shaped portion 3051 is detachably provided with sandpaper for cleaning the outer surface of the seamless steel pipe 3 .

[0036] It also includes a conduit 306 and a branch pipe 307; one of the fixing frames 303 is fixedly connected to a conduit 306 through a mounting block; and two branch pipes 307 are fixedly connected to and communicated with the conduit 306.

[0037] It also includes an interception plate 11, an electric actuator VII 401, a connecting plate 402, an air pipe 403, a cylinder 404, an air bag I 405, a three-way pipe 406, an electromagnetic valve 4061, a ring sleeve 407 and an air bag II 408; the cutting machine 1 is installed with an interception plate 11; two electric actuators VII 401 are fixed to the outer shell of the cutting machine 1, and the electric actuators VII 401 are electric push rods; the telescopic parts of all electric actuators VII 401 are fixed to a connecting plate 402; three air pipes 403 are fixed to the connecting plate 402, and each air pipe 403 is provided with An interface connected to the outside world; each air pipe 403 is fixedly connected to and connected with a cylinder 404, and the cylinder 404 is provided with a plurality of inclined through holes at equal intervals in a ring shape; the outer ring surface of each cylinder 404 is fixedly connected to an air bag I 405; each air pipe 403 is fixedly connected to and connected with a three-way pipe 406; each three-way pipe 406 is installed with a solenoid valve 4061; the outer ring surface of each air pipe 403 is fixedly connected to a ring sleeve 407, and the ring sleeve 407 is made of rubber; the outer ring surface of each ring sleeve 407 is fixedly connected to an air bag II 408.

[0038] Furthermore, since the outer surface of the seamless steel pipe 3 is prone to rust and impurities during transportation and after long-term storage, when the seamless steel pipe 3 is inspected, the rust and impurities on the outer surface of the seamless steel pipe 3 are squeezed onto another adjacent seamless steel pipe 3 due to the rotation of the seamless steel pipe 3, causing radial runout of the seamless steel pipe 3, which is prone to misjudgment. In order to solve the above problem, the external air pump is connected to the conduit 306 in advance. When the seamless steel pipes 3 are conveyed to the fixed plate I 33 one by one, the right end of the seamless steel pipe 3 passes through the two guide wheels 305, and then the two electric actuators VI 302 are controlled to start and each drives a fixed frame 303 to move. The movement of the fixed frame 303 drives the corresponding motor 304 and the corresponding guide wheel 305 to move synchronously, thereby making the two guide wheels 305 move toward each other, and making the two guide wheels 305 contact with the seamless steel pipe 3, and then the outer surface of the seamless steel pipe 3 is surrounded by the arc portion 3051 on the guide wheel 305, as shown in FIG. Figure 7 As shown, at the same time, the right end of the seamless steel pipe 3 is limited by two baffles 36 and a limit block 310, and then the two motors 304 are controlled to start, and the output shafts of the two motors 304 rotate to drive a guide wheel 305 to rotate, and the rotation direction of the two guide wheels 305 is opposite to the rotation direction of the seamless steel pipe 3, and sandpaper is detachably provided on the arc portion 3051, and then the outer surface of the seamless steel pipe 3 is cleaned by the sandpaper on the arc portion 3051, and at the same time, the two electric sliders Ⅰ32 are started to drive the fixed plate Ⅰ33 to move to the right, thereby driving all connected parts to move, and then driving the seamless steel pipe 3 to move to the right, so that the entire seamless steel pipe 3 passes through the two guide wheels 305, thereby removing the rust and impurities on the outer surface of the seamless steel pipe 3, thereby avoiding the rust and impurities on the outer surface of the seamless steel pipe 3 from being squeezed into another adjacent seamless steel pipe 3 when the seamless steel pipe 3 is inspected, causing radial circular runout of the seamless steel pipe 3, which is prone to misjudgment.

[0039] The external air pump is controlled to operate to suction air, thereby generating negative pressure in the conduit 306 and the two branch pipes 307, and then sucking the rust and impurities falling off the outer surface of the seamless steel pipe 3 through the two branch pipes 307, thereby reducing the possibility of rust and impurities adhering to the outer surface of the seamless steel pipe 3.

[0040] After the cutting machine 1 cuts the seamless steel pipe 3, the temperature at the fracture of the seamless steel pipe 3 is high. When the cutting fluid flows to the fracture of the seamless steel pipe 3, the temperature at the fracture of the seamless steel pipe 3 drops suddenly, which can easily cause the incision of the seamless steel pipe 3 to deform. Moreover, under the impact of the cutting fluid, the debris generated when the seamless steel pipe 3 is cut will flow deep into the inner side of the seamless steel pipe 3, thereby affecting the cleanliness of the inner wall of the seamless steel pipe 3. In order to solve the above problem, the external air pump is connected to all the air pipes 403 in advance, and the initial state of the solenoid valve 4061 is open. Before cutting the seamless steel pipe 3, the right end of all seamless steel pipes 3 is located to the right of the saw blade in the cutting machine 1. Then, the two electric actuators Ⅶ401 are controlled to start and jointly drive the connecting plate 402 to move to the right. The movement of the connecting plate 402 drives all the air pipes 403 to move, and then drives all the connected parts to move, so that all the cylinders 404 and airbags I 405 are moved to the inner side of the corresponding seamless steel pipe 3, and the airbag I 405 is also located to the right of the saw blade in the cutting machine 1 to avoid blocking the saw blade in the cutting machine 1. At the same time, the ring sleeve 407 and the airbag II 408 are also moved to the inner side of the seamless steel pipe 3, as shown in FIG. Figure 8 As shown, then, the external air pump is controlled to start and transport cold air to the three air pipes 403, so that the gas enters the air bag I 405 and the air bag II 408 along the air pipe 403 and the three-way pipe 406, so that the air bag I 405 and the air bag II 408 are expanded and pressed against the inner wall of the seamless steel pipe 3, and then the solenoid valve 4061 is controlled to be closed, so that the air bag I 405 and the air bag II 408 are kept in the expanded state, and at the same time, part of the gas will flow into the cylinder 404 through the air pipe 403 and pass through the cylinder 404. The gas flows out from the multiple through holes equidistantly arranged in an annular manner on the cylinder 404 and blows toward the incision of the seamless steel pipe 3, thereby cooling the incision of the seamless steel pipe 3 and reducing the possibility of deformation of the incision of the seamless steel pipe 3. The expanded airbag I 405 intercepts the debris splashed to the inside of the seamless steel pipe 3 during the cutting process of the seamless steel pipe 3. At the same time, the gas discharged through the through holes on the cylinder 404 blows away the debris remaining on the inside of the seamless steel pipe 3, making the inner wall of the seamless steel pipe 3 neater.

[0041] It should be noted that during the cutting process of the seamless steel pipe 3, the airbag I 405 and the airbag II 408 are always located in the seamless steel pipe 3, so that when the seamless steel pipe 3 is cut, the cylinder 404, the airbag I 405, the ring sleeve 407 and the airbag II 408 work together to support the seamless steel pipe 3, so as to avoid the problem that the seamless steel pipe 3 is bent due to its own gravity when the cutting machine 1 is about to cut the seamless steel pipe 3, resulting in an uneven cut of the seamless steel pipe 3, and after the seamless steel pipe 3 is completely cut, the cut seamless steel pipe 3 is located on the airbag I 405 and the airbag II 408, and then the two electric actuators Ⅶ 401 are controlled to start and drive all connected parts to move and reset, thereby driving the cut seamless steel pipe 3 to move, and then the seamless steel pipe 3 is intercepted by the interception plate 11 on the cutting machine 1, so that the seamless steel pipe 3 is separated from the airbag I 405 and the airbag II 408, and then the cut seamless steel pipe 3 is collected.

[0042] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
