Description

Technical Field

[0001] The present invention relates to the technical field of steel pipe cutting, and in particular to an intelligent cutting device and a cutting method. Background Art

[0002] Steel pipe is a kind of steel with a hollow cross-section, whose length is much longer than its diameter or circumference. Steel pipe is not only used to transport fluids and powdered solids, exchange heat energy, and manufacture mechanical parts and containers, but it is also an economical steel. Using steel pipe to manufacture building structure grids, pillars and mechanical supports can reduce weight, save 20-40% of metal, and realize factory-based mechanized construction. Using steel pipe to manufacture highway bridges can not only save steel and simplify construction, but also greatly reduce the area of ​​protective coating, saving investment and maintenance costs.

[0003] Steel pipes often need to be cut into different lengths during actual use. Chinese patent CN112916946B discloses a fully automatic steel pipe cutting device and a method of using the same. The steel pipe cutting assembly is fixedly mounted on a frame, the steel pipe cutting assembly is used to cut the steel pipe, the steel pipe clamping assembly is used to clamp and fix the steel pipe, and the driving assembly drives the steel pipe clamping assembly to move relative to the steel pipe cutting assembly. The present invention uses an input assembly to automatically transport the steel pipe to the frame, the steel pipe is automatically clamped by the steel pipe clamping assembly, and after the steel pipe cutting is completed, the steel pipe falls onto the elastic plate of the transport assembly, rolls onto the conveyor belt under gravity and finally leaves the frame, and does not require manual participation in loading, unloading and clamping, thereby solving the problem of low production efficiency caused by manual loading and unloading of existing equipment; the cutting assembly does not move, and the steel pipe moves toward the cutting knife under the drive of the driving assembly, and the cutting knife does not need to move, thereby solving the problem of decreased steel pipe cutting accuracy caused by the movement of the cutting knife.

[0004] The device has the following shortcomings:

[0005] (1) The device uses a hydraulic cylinder to push the steel pipe upward for cutting. The moving distance of the hydraulic cylinder is fixed. When cutting steel pipes of different diameters, the steel pipe may be cut but the hydraulic cylinder is still pushing the steel pipe upward, which will increase the wear of the blade and cause the steel pipe cut surface to be uneven.

[0006] (2) The steel pipe on the device relies on gravity to roll on the inclined plane to complete loading, cutting and unloading. Therefore, the device can only cut round steel pipes, and cannot cut steel pipes of other shapes, such as square steel pipes, because steel pipes of other shapes cannot roll on the inclined plane, cannot be loaded, and the clamping assembly cannot be clamped, so the versatility is low. Summary of the invention

[0007] The content of this application is used to introduce concepts in a brief form, which will be described in detail in the detailed implementation section below. The content of this application is not intended to identify the key features or essential features of the technical solution claimed for protection, nor is it intended to limit the scope of the technical solution claimed for protection.

[0008] In order to solve the technical problems mentioned in the above background technology section, some embodiments of the present application provide an intelligent cutting device and a cutting method, including a shell, a lower hopper fixed on the shell, a cutting mechanism fixed on the shell, a conveying mechanism fixed on the shell, and a measuring mechanism fixed on the shell;

[0009] The cutting mechanism comprises a first electric slide rail symmetrically fixed on the housing, a first bottom plate slidably arranged on the first electric slide rail, a clamping assembly symmetrically arranged on the bottom plate, a plurality of second electric slide rails fixed on the housing, a second bottom plate slidably arranged on the second electric slide rail, a first motor fixed on the second bottom plate, a reduction box fixed on the bottom plate and connected to the first motor, and a blade rotatably arranged on the reduction box;

[0010] The conveying mechanism includes a second motor fixed on the shell, a first rotating shaft rotatably arranged on the shell and connected to the second motor, a second rotating shaft rotatably arranged on the shell, a first roller fixed on the first rotating shaft, a second roller fixed on the second rotating shaft, a conveyor belt sleeved on the first roller and the second roller, a booster assembly symmetrically fixed on the first rotating shaft and the second rotating shaft, a support plate symmetrically arranged on the shell, a rotating plate rotatably arranged on the support plate, and a material discharge channel fixed on the shell;

[0011] The measuring mechanism includes a first slide groove symmetrically fixed on the shell, a first measuring head slidably arranged on the first slide groove, a second slide groove symmetrically fixed on the shell, a second measuring head slidably arranged on the second slide groove, a first rack fixed on the first measuring head, a second rack fixed on the second measuring head, a first gear rotatably arranged on the shell and meshing with the first rack, a second gear rotatably arranged on the shell and meshing with the second rack and the first gear, and a limit assembly fixed on the shell and connected to the second measuring head.

[0012] Specifically, the clamping assembly includes a plurality of first hydraulic cylinders fixed on the first base plate, a third base plate fixed on the first hydraulic cylinder, a sixth slide groove fixed on the third base plate, a second hydraulic cylinder fixed on the third base plate, a first clamping petal slidably arranged on the sixth slide groove and fixedly connected to the second hydraulic cylinder, a second clamping petal fixed on the third base plate, and an unlocking device fixed on the third base plate.

[0013] Specifically, the unlocking device includes a seventh slide groove fixed on the third base plate, a detection head slidably arranged on the seventh slide groove, a third slide groove fixed on the third base plate, an unlocking head slidably arranged on the third slide groove, a first spring with one end fixed on the detection head and the other end fixed on the third base plate, a third gear rotatably arranged on the third base plate and meshed with the detection head, and a fourth gear rotatably arranged on the third base plate and meshed with the third gear and the unlocking head.

[0014] Specifically, the booster assembly includes a first sprocket fixed on the first rotating shaft, a second sprocket fixed on the second rotating shaft, a third sprocket fixed on the first rotating shaft, a fourth sprocket fixed on the second rotating shaft, a first chain sleeved on the first sprocket and the second sprocket, a second chain sleeved on the third sprocket and the fourth sprocket, a plurality of bases fixed on the first chain and the second chain, a booster rod rotatably arranged on the base, a second spring fixed on the base and connected to the booster rod, and a compression plate symmetrically fixed on the shell.

[0015] Specifically, the limit assembly includes a fourth slide groove symmetrically fixed on the shell, a connecting rod slidably arranged on the fourth slide groove and connected to the second measuring head, a rack fixed on the shell, a fifth slide groove fixed on the connecting rod, a locking rod slidably arranged on the fifth slide groove, a plurality of third springs with one end fixed on the locking rod and the other end fixed on the connecting rod, a through hole fixed on the connecting rod, and an unlocking hole fixed on the locking rod.

[0016] Specifically, the initial position of the bottom of the first measuring head is located at one-half of the channel; the initial position of the bottom of the second measuring head is in contact with the conveyor belt.

[0017] An intelligent cutting method comprises the following steps:

[0018] a. Put the steel pipe from the lower hopper, and the steel pipe rolls down to the conveyor belt through the channel. The second motor drives the conveyor belt and the booster assembly to work and push the steel pipe to move;

[0019] b. During the movement, the steel pipe contacts the first measuring head, pushing the first measuring head upward. The first measuring head drives the second gear to rotate through the first rack and the first gear. The second gear drives the second measuring head to move upward by an end distance. After passing through the first measuring head, the steel pipe contacts the second measuring head and pushes the second measuring head to move upward. The second measuring head moves upward and drives the limit assembly to move upward, thereby determining the upward movement distance of the first hydraulic cylinder. The steel pipe moves to the turn plate with the conveyor belt and slides into the clamping assembly through the turn plate.

[0020] b. The second hydraulic cylinder pushes the first clamping petal to move and clamp the steel pipe. The first hydraulic cylinder moves upward, and the steel pipe contacts the blade for cutting. When the upper end surface of the third bottom plate contacts the lower end surface of the connecting rod, the unlocking head penetrates the unlocking hole, driving the locking rod to move and release the lock;

[0021] d. The first hydraulic cylinder moves downward, and the connecting rod and the second measuring head move downward due to their own weight to reset and perform the next cutting.

[0022] The beneficial effects of the present invention are:

[0023] (1) In the existing cutting device, the distance that the steel pipe moves during cutting is fixed, resulting in that when cutting steel pipes of different diameters, even if the steel pipe has been cut, the hydraulic cylinder is still driving the steel pipe to move, causing unnecessary friction between the blade and the steel pipe, which increases the wear of the blade. By providing an unlocking device and a limit device and cooperating with a measuring mechanism, when cutting steel pipes of different diameters, the diameter of the steel pipe can be automatically measured and the moving distance of the first hydraulic cylinder can be adjusted. When the blade just cuts the steel pipe, it works in the reverse direction to disengage the blade from the steel pipe, thereby reducing unnecessary friction, reducing blade wear, and increasing the service life of the blade.

[0024] (2) It can cut rectangular steel pipes and circular steel pipes. When cutting a steel pipe with a rectangular cross-section, when the steel pipe is clamped by the first clamping flap, the steel pipe will contact the detection head and push the detection head to move downward. The downward movement of the detection head drives the third gear to rotate. The rotation of the third gear drives the fourth gear to rotate. The fourth gear moves the unlocking head downward. The function of the detection head is to detect whether the clamping piece is a circular steel pipe or a rectangular steel pipe. Since the lowest point of the blade is aligned with the top of the steel pipe by default, this cutting method will cause the lowest point of the blade to cut the center point of the bottom edge of the rectangular steel pipe when cutting a rectangular steel pipe, but the two sides of the bottom edge of the rectangular steel pipe are not cut. Therefore, it is necessary to set a detection head to detect the shape of the steel pipe and switch the cutting mode. When the detection head detects that it is a rectangular steel pipe, the first electric The movable slide rail drives the first base plate to move to one end of the first electric slide rail close to the rotating plate, and the rotating plate is pushed to rotate. At this time, the first hydraulic cylinder pushes the third base plate and the steel pipe to move upward, and stops working when they contact the limit assembly. The detection head is squeezed, causing the unlocking head to move into the third base plate, and the limit assembly cannot be unlocked. At this time, the first electric slide rail drives the first base plate to move and starts cutting from the side of the rectangular steel pipe. After the cutting is completed, the rectangular steel pipe is taken out, the first electric slide rail drives the first base plate to reset, and the first hydraulic cylinder pushes the third base plate to move upward. Since the steel pipe has been taken out, the detection head and the unlocking head are reset. Therefore, the unlocking head can contact the limit assembly as the third base plate moves upward, and the limit assembly is unlocked, and the limit assembly can be reset by self-resetting.

[0025] (3) The diameter of the steel pipe is measured by setting a first measuring head and a second measuring head, and the steel pipes of different diameters and different shapes are adapted. A booster rod is set to assist the steel pipe in measurement. Since the friction between the conveyor belt and the steel pipe is small, when the steel pipe contacts the first measuring head, the steel pipe cannot push the first measuring head upward. Therefore, a booster rod is required to assist the steel pipe in pushing the first measuring head upward. One side of the compression plate is an inclined surface, and the inclined surface is located on the right side of the second measuring head. It is used to push the booster rod to rotate and be horizontal with the first chain and the second chain. If the compression plate is not set, when the booster rod pushes the steel pipe to contact the second measuring head, due to the inclined surface on the second measuring head, the second measuring head will push the steel pipe upward. A force perpendicular to the inclined plane is applied, and the steel pipe will also apply a thrust to the booster rod, which will rotate and tilt. Because the force acts on each other, the booster rod will also apply a force in the tilt direction to the steel pipe, causing the steel pipe to be slightly lifted by the booster rod. The steel pipe will also apply a force in the tilt direction to the second measuring head, causing the second measuring head to move upward to a height greater than the actual diameter of the steel pipe, resulting in measurement errors, which in turn affects the cutting. Therefore, the compression plate needs to be set on the right side of the second measuring head, and the steel pipe is pushed to a horizontal position by the compression plate before it contacts the second measuring head. Because the second measuring head will be driven upward by the first measuring head to move a certain distance, the steel pipe can pass through the second measuring head even without the booster rod.

[0046] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0047] Reference Figure 1-Figure 13 As shown, an intelligent cutting device and cutting method described in the present invention include a shell 1, a lower hopper 2 fixed on the shell, a cutting mechanism 3 fixed on the shell, a conveying mechanism 4 fixed on the shell, and a measuring mechanism 5 fixed on the shell; the lower hopper is provided with an inclined surface to facilitate the steel pipe to roll or slide to the conveying mechanism; the conveying mechanism is used to convey the steel pipe to the cutting mechanism, and cooperates with the measuring mechanism to measure the steel pipe during the conveying process, and the measuring mechanism limits the moving distance of the cutting mechanism according to the measured value, so as to prevent the blade from still contacting and rubbing with the steel pipe after cutting the steel pipe, thereby extending the service life of the blade;

[0048] The cutting mechanism includes a first electric slide rail 31 symmetrically fixed on the housing, a first bottom plate 32 slidably arranged on the first electric slide rail, a clamping assembly 33 symmetrically arranged on the bottom plate, a plurality of second electric slide rails 34 fixed on the housing, a second bottom plate 35 slidably arranged on the second electric slide rail, a first motor 36 fixed on the second bottom plate, a reduction box 37 fixed on the bottom plate and connected to the first motor, and a blade 38 rotatably arranged on the reduction box; the first bottom plate can slide on the first electric slide rail, and the initial position of the first bottom plate is located at the center of the first electric slide rail; the clamping assembly is used to clamp the steel pipe; the second bottom plate can slide on the second electric slide rail, thereby driving the first motor, the reduction box and the blade to move and adjust the cutting position;

[0049] The conveying mechanism includes a second motor 41 fixed on the shell, a first rotating shaft 42 rotatably arranged on the shell and connected to the second motor, a second rotating shaft 43 rotatably arranged on the shell, a first roller 44 fixed on the first rotating shaft, a second roller 45 fixed on the second rotating shaft, a conveyor belt 46 sleeved on the first roller and the second roller, a booster assembly 47 symmetrically fixed on the first rotating shaft and the second rotating shaft, a support plate 48 symmetrically arranged on the shell, a rotating plate 49 rotatably arranged on the support plate, and a material discharge channel 40 fixed on the shell; the second motor drives the first rotating shaft and the second rotating shaft to work, thereby rotating the first roller and the second roller to make the conveyor belt work; the interval part of the conveyor belt is filled to prevent the steel pipe from pressing the conveyor belt and causing the conveyor belt to sink; a torsion spring is arranged between the rotating plate and the support plate for resetting the rotating plate; the steel pipe enters the material discharge channel from the discharge hopper, then falls on the conveyor belt, moves under the operation of the booster assembly and the conveyor belt, and rolls into the cutting mechanism from above the rotating plate after passing through the measuring mechanism;

[0050] The measuring mechanism includes a first slide groove 51 symmetrically fixed on the shell, a first measuring head 52 slidably arranged on the first slide groove, a second slide groove 53 symmetrically fixed on the shell, a second measuring head 54 slidably arranged on the second slide groove, a first rack 55 fixed on the first measuring head, a second rack 56 fixed on the second measuring head, a first gear 57 rotatably arranged on the shell and meshing with the first rack, a second gear 58 rotatably arranged on the shell and meshing with the second rack and the first gear, and a limit assembly 59 fixed on the shell and connected to the second measuring head; the first measuring head and the second measuring head are provided with inclined surfaces to facilitate the passage of the steel pipe; the diameter of the second gear is larger than the first gear; when the diameter of the steel pipe is larger than half the width of the feeding channel, the steel pipe will first squeeze the first measuring head, the first measuring head moves upward to drive the first gear to rotate, the first gear drives the second gear to rotate, the second gear drives the second measuring head to move upward, the moving distance of the second measuring head is greater than the first measuring head, when encountering a steel pipe with a larger diameter, the first measuring head The first measuring head drives the second measuring head to move upward, so that the second measuring head can be in a position higher than the radius of the steel pipe before contacting the steel pipe, so that the steel pipe can pass through the second measuring head smoothly and push the second measuring head to move to measure the diameter; when the diameter of the steel pipe is less than half the width of the feeding channel, the steel pipe will directly push the second measuring head to move upward to measure the diameter; the center distance between the first measuring head and the second measuring head is slightly less than half the width of the feeding channel. When the diameter of the steel pipe is slightly larger than half the width of the feeding channel, this setting can make the right side of the steel pipe still contact with the first measuring head when the left side contacts the second measuring head. If the distance between the first measuring head and the second measuring head is large, when a steel pipe with a diameter slightly larger than half the width of the feeding channel passes through, due to the large distance between the first measuring head and the second measuring head, the steel pipe cannot contact the second measuring head after passing through the first measuring head, and the second measuring head and the first measuring head will be self-repositioned, causing the steel pipe to be stuck between the first measuring head and the second measuring head. Therefore, the center distance between the first measuring head and the second measuring head needs to be slightly smaller than half the width of the feeding channel.

[0051] Specifically, the clamping assembly includes a plurality of first hydraulic cylinders 331 fixed on the first base plate, a third base plate 332 fixed on the first hydraulic cylinder, a sixth slide groove 333 fixed on the third base plate, a second hydraulic cylinder 334 fixed on the third base plate, a first clamping petal 335 slidably arranged on the sixth slide groove and fixedly connected to the second hydraulic cylinder, a second clamping petal 336 fixed on the third base plate, and an unlocking device 337 fixed on the third base plate; when the steel pipe rolls in from the rotating plate, the steel pipe falls on the third base plate, and the second hydraulic cylinder pushes the first clamping petal to clamp the steel pipe; the first hydraulic cylinder pushes the third base plate to move upward, so that the steel pipe contacts the blade to cut the steel pipe.

[0052] Specifically, the unlocking device includes a seventh slide groove 3371 fixed on the third bottom plate, a detection head 3372 slidably arranged on the seventh slide groove, a third slide groove 3376 fixed on the third bottom plate, an unlocking head 3377 slidably arranged on the third slide groove, a first spring 3373 with one end fixed on the detection head and the other end fixed on the third bottom plate, a third gear 3374 rotatably arranged on the third bottom plate and meshing with the detection head, and a fourth gear 3375 rotatably arranged on the third bottom plate and meshing with the third gear and the unlocking head; when clamping the circular steel pipe, the steel pipe will not contact the detection head. At this time, when the third bottom plate moves upward, after moving to a certain distance, the unlocking head will contact the limit assembly, so that the limit assembly The limit is released. At this time, the blade just completely cuts the steel pipe, and the first hydraulic cylinder works in the reverse direction to drive the third bottom plate to move downward, so that the steel pipe is separated from the blade. In the existing cutting device, the distance that the steel pipe moves during cutting is fixed, resulting in that when cutting steel pipes of different diameters, even if the steel pipe has been cut, the hydraulic cylinder is still driving the steel pipe to move, resulting in unnecessary friction between the blade and the steel pipe, which increases the wear of the blade. By providing an unlocking device and a limit device and cooperating with a measuring mechanism, when cutting steel pipes of different diameters, the diameter of the steel pipe can be automatically measured and the moving distance of the first hydraulic cylinder can be adjusted. When the blade just cuts the steel pipe, it works in the reverse direction to separate the blade from the steel pipe, thereby reducing unnecessary friction, reducing blade wear, and increasing Increase the service life of the blade; when cutting a steel pipe with a rectangular cross-section, when the steel pipe is clamped by the first clamping flap, the steel pipe will contact the detection head and push the detection head to move downward. The downward movement of the detection head drives the third gear to rotate, and the rotation of the third gear drives the fourth gear to rotate. The fourth gear moves the unlocking head downward. The function of the detection head is to detect whether the clamping piece is a round steel pipe or a rectangular steel pipe. Since the lowest point of the blade is aligned with the top of the steel pipe by default, this cutting method will cause the lowest point of the blade to cut the center point of the bottom edge of the rectangular steel pipe when cutting a rectangular steel pipe, but the two sides of the bottom edge of the rectangular steel pipe are not cut. Therefore, it is necessary to set the detection head to detect the shape of the steel pipe and switch the cutting mode. When the detection head detects that it is a rectangular steel pipe, the first electric slide rail drives The first bottom plate is moved to one end of the first electric slide rail close to the rotating plate, and the rotating plate is pushed to rotate. At this time, the first hydraulic cylinder pushes the third bottom plate and the steel pipe to move upward, and stops working when they touch the limit assembly. The detection head is squeezed, causing the unlocking head to move into the third bottom plate, and the limit assembly cannot be unlocked. At this time, the first electric slide rail drives the first bottom plate to move, and cutting starts from the side of the rectangular steel pipe. After the cutting is completed, the rectangular steel pipe is taken out, the first electric slide rail drives the first bottom plate to reset, and the first hydraulic cylinder pushes the third bottom plate to move upward. Since the steel pipe has been taken out, the detection head and the unlocking head are reset. Therefore, the unlocking head can contact the limit assembly as the third bottom plate moves upward, and the limit assembly is unlocked, and the limit assembly can be reset by self-resetting.

[0053] Specifically, the booster assembly includes a first sprocket 471 fixed on the first rotating shaft, a second sprocket 472 fixed on the second rotating shaft, a third sprocket fixed on the first rotating shaft, a fourth sprocket fixed on the second rotating shaft, a first chain 475 sleeved on the first sprocket and the second sprocket, a second chain 476 sleeved on the third sprocket and the fourth sprocket, a plurality of bases 477 fixed on the first chain and the second chain, a booster rod 478 rotatably arranged on the base, and a plurality of bases 477 fixed on the base and connected to the booster rod. The second spring 479 and the compression plate 470 symmetrically fixed on the housing; the first rotating shaft can drive the first sprocket and the third sprocket to rotate synchronously, and drive the second sprocket and the fourth sprocket to rotate through the first chain and the second chain. The first chain and the second chain are provided with multiple bases, and a booster rod is rotatably provided on the base; the second spring is a torsion spring; the booster rod is used to push the steel pipe to move on the conveyor belt. Due to the small friction between the conveyor belt and the steel pipe, when the steel pipe contacts the first measuring head, the steel pipe cannot push the first measuring head upward. Therefore, it is necessary to set a booster rod to assist the steel pipe to push the first measuring head upward; one side of the compression plate is an inclined surface, and the inclined surface is located on the right side of the second measuring head, which is used to push the booster rod to rotate and be horizontal with the first chain and the second chain. If the compression plate is not set, when the booster rod pushes the steel pipe to contact the second measuring head, due to the inclined surface on the second measuring head, the second measuring head will apply a force perpendicular to the inclined surface to the steel pipe, and then the steel pipe will also apply a thrust to the booster rod, and the booster rod will rotate and tilt. Because the force is mutual, the booster rod will also apply a force in the inclined direction to the steel pipe, causing the steel pipe to be slightly lifted by the booster rod, and the steel pipe will also apply a force in the inclined direction to the second measuring head, causing the second measuring head to move upward at a height greater than the actual diameter of the steel pipe, resulting in measurement errors, which in turn affects the cutting. Therefore, the compression plate needs to be set on the right side of the second measuring head, and the steel pipe is pushed to a horizontal position by the compression plate before it contacts the second measuring head. Because the second measuring head will be driven upward by the first measuring head to move a certain distance, the steel pipe can pass through the second measuring head even without the booster rod.

[0054] Specifically, the limit assembly includes a fourth slide groove 591 symmetrically fixed on the shell, a connecting rod 592 slidably arranged on the fourth slide groove and connected to the second measuring head, a rack 593 fixed on the shell, a fifth slide groove 594 fixed on the connecting rod, a locking rod 595 slidably arranged on the fifth slide groove, a plurality of third springs 596 with one end fixed on the locking rod and the other end fixed on the connecting rod, a through hole 597 fixed on the connecting rod, and an unlocking hole 598 fixed on the locking rod; the locking rod is meshed with the rack; the third spring is a compression spring; the unlocking hole is provided with an inclined surface; when the second measuring head moves upward, it drives the connecting rod to move upward together, changing the meshing position of the locking rod and the rack, and when the third base plate moves upward, the unlocking head enters the through hole and pushes the locking rod to move through the unlocking hole, so that the locking rod is out of contact with the rack and the limit is released.

[0055] Specifically, the initial position of the bottom of the first measuring head is located at one-half of the channel; the initial position of the bottom of the second measuring head is in contact with the conveyor belt.

[0056] An intelligent cutting method comprises the following steps:

[0057] a. Put the steel pipe from the lower hopper, and the steel pipe rolls down to the conveyor belt through the channel. The second motor drives the conveyor belt and the booster assembly to work and push the steel pipe to move;

[0058] b. During the movement, the steel pipe contacts the first measuring head, pushing the first measuring head upward. The first measuring head drives the second gear to rotate through the first rack and the first gear. The second gear drives the second measuring head to move upward by an end distance. After passing through the first measuring head, the steel pipe contacts the second measuring head and pushes the second measuring head to move upward. The second measuring head moves upward and drives the limit assembly to move upward, thereby determining the upward movement distance of the first hydraulic cylinder. The steel pipe moves to the turn plate with the conveyor belt and slides into the clamping assembly through the turn plate.

[0059] b. The second hydraulic cylinder pushes the first clamping petal to move and clamp the steel pipe. The first hydraulic cylinder moves upward, and the steel pipe contacts the blade for cutting. When the upper end surface of the third bottom plate contacts the lower end surface of the connecting rod, the unlocking head penetrates the unlocking hole, driving the locking rod to move and release the lock;

[0060] d. The first hydraulic cylinder moves downward, and the connecting rod and the second measuring head move downward due to their own weight to reset and perform the next cutting.

[0061] The above descriptions are only some preferred embodiments of the present disclosure and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by a specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned inventive concept.
