Description

Technical Field

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

[0002] Metal pipes are widely used in the field of mechanical manufacturing. They are mainly used for transmission, support, positioning and other aspects of mechanical equipment. They can also be used to manufacture automobiles, aircraft, ships, etc. When using them, metal pipes are often cut into equal parts.

[0003] There are many existing technologies for metal pipe cutting devices, such as:

[0004] Chinese patent publication number CN213351009U discloses a metal pipe cutting device, including a protective box, lifting cylinders are symmetrically arranged at the four corners of the bottom of the protective box, a shock-absorbing plate is arranged at the bottom of the lifting cylinder, an adjusting motor is installed on the left side of the top of the protective box, a driving pulley is arranged at the output end of the adjusting motor, and bearing seats are symmetrically inserted at the upper parts of the left and right side walls of the protective box. The utility model provides a metal pipe cutting device. Through the design and use of a series of structures, the patent can achieve the purpose of quickly collecting and cleaning the flying sparks and debris generated during the cutting process during use, avoiding harm to the workers' eyes, which is very dangerous and will cause great difficulty in cleaning the debris later, and can be adjusted according to the different heights of the workers, thereby improving the practicality of the metal pipe cutting device.

[0005] However, in actual use, there are still some problems that need to be solved:

[0006] 1. When the existing cutting device is in operation, the cutting end needs to be manually clamped during the cutting process to ensure the stability of the metal pipe during cutting. After the cutting is completed, the cut metal pipe needs to be manually unloaded. However, since the surface of the metal pipe will become hot due to friction during the cutting process, the operator can easily be burned during the subsequent unloading operation if he is not careful. This undoubtedly poses a serious safety threat to the operators, buries safety hazards that cannot be ignored, and greatly limits the improvement of work efficiency and the realization of safe production goals;

[0007] 2. When performing metal pipe cutting operations, once the task of angle cutting of batches of metal pipes is involved, the existing operating mode exposes obvious drawbacks. Currently, it mainly relies on operators to rely on experience and conventional tools to perform angle positioning and cutting operations. This process is not only cumbersome and complicated, but also requires a high level of skill from the operators, resulting in frequent angle deviations during the cutting process, which requires repeated adjustments and corrections, making the cutting efficiency extremely low and difficult to meet large-scale needs.

[0008] Therefore, a metal pipe cutting device and its usage method are proposed. Summary of the Invention

[0009] The purpose of the present invention is to provide a metal pipe cutting device and its usage method to solve the problems raised in the above-mentioned background technology.

[0010] To solve the above technical problems, one of the purposes of the present invention is to provide a metal pipe cutting device, including a machine table. A moving rail and a fixed rack are provided on the surface of the machine table. The fixed rack is arranged close to the side of the machine table. A moving seat is provided on the surface of the moving rail. A clamping assembly is provided on one side of the moving seat. The clamping assembly is used to clamp the metal pipe. The moving seat moves horizontally on the surface of the moving rail. Rotating motors are provided on both sides of the moving seat. Half gears are provided at the output ends of the rotating motors. When the half gears rotate on the surface of the fixed rack, the moving seat is driven to move horizontally, and the moving distance is the cutting length of the steel pipe. A vertical frame is provided on one side of the machine table away from the clamping assembly. A cutting machine is provided inside the vertical frame. An adjusting assembly is provided above the cutting machine. The adjusting assembly is used to adjust the cutting angle of the cutting machine. Long racks are provided on both sides of the rotating motors. Fixed assemblies are provided on both sides of the vertical frame. When the long racks pass through the fixed assemblies, the cutting part is automatically clamped and limited. After cutting is completed, the fixed assemblies release the clamping and limiting of the cut metal pipe.

[0011] As a further improvement of the technical solution, a through hole is provided on the surface of the machine table near the lower part of the cutting machine. A collection box is provided below the machine table. The cut metal pipe falls into the interior of the collection box through the through hole for collection.

[0012] As a further improvement of the technical solution, an electric telescopic rod is provided on the surface of the machine table near one side of the vertical frame. A rotating roller is provided at the end of the electric telescopic rod. The top of the rotating roller is in contact with the bottom of the metal pipe clamped inside the clamping assembly.

[0013] As a further improvement of the technical solution, the clamping assembly includes a sealed box provided on the surface of the moving seat. A first motor is provided at the end of the sealed box. The first motor penetrates inside the sealed box and a main gear is provided at its end. A secondary gear is provided beside the main gear. The secondary gears are arranged in an array. A lead screw is provided inside the secondary gear. Clamping plates are provided on the surface of the lead screw. When the main gear rotates to drive the secondary gears to mesh and rotate, the clamping plates provided on the surface of the lead screw move relative to each other to clamp the metal pipe.

[0014] As a further improvement of the technical solution, the adjusting assembly includes a machine box provided on the top of the cutting machine. A rotating rod penetrates the machine box on the top of the cutting machine. A cylinder is provided on the top of the machine box. The piston rod at the end of the control cylinder drives the cutting machine to move downward in the vertical direction.

[0015] As a further improvement of the technical solution, a second motor is provided on one side of the chassis. The output end of the second motor penetrates the chassis and a worm is provided at the end. A turbine is provided on one side of the worm. The turbine is clamped on the surface of the rotating rod. Control the output end of the second motor to drive the worm to rotate, so that the turbine meshes and rotates, and the rotation of the turbine adjusts the cutting angle of the cutting machine.

[0016] As a further improvement of the technical solution, the fixing assembly includes support columns provided on both sides of the surface of the machine table. Column cylinders are provided on the surfaces of the support columns. An extrusion plate is slidably provided on the inner wall of the column cylinder. A compression spring is provided between the column cylinder and the extrusion plate. A compression block is provided at the bottom of the extrusion plate. The compression block penetrates the bottom of the column cylinder to the outside. In the natural state, the extrusion plate is away from the surface of the metal pipe to be cut under the action of the compression spring. By pressing the compression block, the extrusion plate slides on the inner wall of the column cylinder to clamp and fix the cutting end of the metal pipe.

[0017] As a further improvement of the technical solution, a gear shaft is provided on one side of the column. An eccentric wheel is provided on the side of the gear shaft close to the inner wall of the column. A rotating gear is provided at the end of the eccentric wheel. Rotate the gear shaft to drive the rotating gear to mesh and rotate. When the rotating gear rotates, it drives the eccentric wheel to rotate coaxially.

[0018] As a further improvement of the technical solution, when the moving seat drives the long rack to move horizontally, the long rack drives the gear shaft to rotate one week.

[0019] The second object of the present invention is to provide a processing method for a metal pipe cutting device, including the metal pipe cutting device described in any one of the above, including the following steps:

[0020] S1. Move the metal pipe to be cut to the end of the sealed box. Control the output shaft of the first motor to drive the main gear to rotate. When the main gear rotates, it drives the sub-gear to mesh and rotate. When the sub-gear rotates, the lead screw provided on its surface rotates coaxially. When the lead screw rotates, the clamping plate moves on the lead screw to clamp and fix the end of the metal pipe.

[0021] S2. Control the output shaft of the second motor to rotate. The output shaft of the second motor drives the worm to rotate coaxially. When the worm rotates, it drives the turbine to mesh and rotate. By drawing angle lines on the top of the cutting machine and observing the rotation angle of the cutting machine, when the cutting machine rotates to the set angle, the output shaft of the second motor stops rotating. Due to the self-locking property of the worm, the cutting angle of the cutting machine is fixed. Control the output end of the cylinder to drive the chassis to move downward in the vertical direction. The cutting machine is driven by the chassis to cut the metal pipe at an angle.

[0022] S3. Drive the half gear to rotate by controlling the output end of the rotation motor. One rotation of the half gear is the length that the metal pipe needs to be cut. When the moving seat moves, it drives the long rack to move. When the long rack moves, it drives the gear shaft to mesh and rotate. The moving path of the long rack drives the gear shaft to rotate one week. When the gear shaft rotates, it drives the rotating gear to mesh and rotate. When the rotating gear rotates, it makes the eccentric wheel rotate to squeeze the end of the compression block, so that the compression block pushes the extrusion plate to move relatively to clamp and fix the metal pipe. Control the cutting machine to move down to cut the metal pipe. Since the extrusion plate limits the metal pipe at the cutting position, the cut metal pipe is prevented from popping out. When the cutting is completed, control the cutting machine to move away from the cutting position. When the output end of the rotation motor drives the half gear to rotate, the moving seat moves to feed and cut the metal pipe. During the process of the moving seat driving the long rack to move, the gear shaft drives the rotating gear to mesh and rotate. At the same time, the eccentric wheel rotates coaxially with the rotating gear. While the eccentric wheel rotates, the pressure on the compression block gradually disappears, and the extrusion plate is reset under the action of the compression spring, so that the clamping force on the cut metal pipe disappears, and the metal pipe falls under the action of gravity and enters the collection box through the through hole for automatic collection.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] 1. For this metal pipe cutting equipment, control the rotation of the output shaft of the second motor. The output shaft of the second motor drives the worm to rotate coaxially. When the worm rotates, it drives the turbine to mesh and rotate. By drawing angle lines on the top of the cutting machine and observing the rotation angle of the cutting machine, when the cutting machine rotates to the set angle, the output shaft of the second motor stops rotating. Due to the self-locking property of the worm, the cutting angle of the cutting machine is fixed. Control the output end of the cylinder to drive the machine box to move down vertically. During the movement of the machine box, it drives the cutting machine to perform angle cutting on the metal pipe, so as to realize rapid batch angle cutting of metal pipes and improve the cutting processing efficiency.

[0025] 2. For this metal pipe cutting equipment, control the output end of the rotation motor to drive the half gear to rotate. One rotation of the half gear is the length that the metal pipe needs to be cut. When the moving seat moves, it drives the long rack to move. When the long rack moves, it drives the gear shaft to mesh and rotate. The moving path of the long rack drives the gear shaft to rotate one week. When the gear shaft rotates, it drives the rotating gear to mesh and rotate. When the rotating gear rotates, it makes the eccentric wheel rotate to squeeze the end of the compression block, so that the compression block pushes the extrusion plate to move relatively to clamp and fix the metal pipe. Control the cutting machine to move down to cut the metal pipe. Since the extrusion plate limits the metal pipe at the cutting position, the cut metal pipe is prevented from popping out and hitting the operator, avoiding potential safety hazards.

[0026] 3. For this metal pipe cutting equipment, when the cutting machine is controlled to move away from the cutting position and the output end of the rotating motor drives the semi-gear to rotate, the moving seat moves to feed and cut the metal pipe. During the process of the moving seat driving the long rack to move, the gear shaft drives the rotating gear to mesh and rotate. At the same time, the eccentric wheel rotates coaxially with the rotating gear. While the eccentric wheel rotates, the pressure on the compression block gradually disappears, and the pressing plate is reset under the action of the compression spring, so that the clamping force on the cut metal pipe disappears. The metal pipe drops under the action of gravity and enters the collection box through the through hole for automatic collection, avoiding the scald caused by the operator taking the cut metal pipe.

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] One of the purposes of the present invention is to Figures 1 - 7 As shown, metal pipe cutting equipment is provided, see Figures 1 - 8 The present invention comprises a machine platform 100, a movable rail 101 and a fixed rack 102 are arranged on the surface of the machine platform 100, the fixed rack 102 is arranged near the side of the machine platform 100, a movable seat 200 is arranged on the surface of the movable rail 101, a clamping assembly 300 is arranged on one side of the movable seat 200, the clamping assembly 300 is used to clamp the metal pipe, the movable seat 200 moves horizontally on the surface of the movable rail 101, rotating motors 201 are arranged on both sides of the movable seat 200, and half gears 202 are arranged on the output ends of the rotating motors 201, and the half gears 202 drive the movable seat 200 to move horizontally on the surface of the movable rail 101. The movable seat 200 moves horizontally, and the moving distance is the cutting length of the steel pipe. A vertical frame is provided on the side of the machine table 100 away from the clamping component 300. A cutting machine 105 is provided in the vertical frame. An adjusting component 400 is provided above the cutting machine 105. The adjusting component 400 is used to adjust the cutting angle of the cutting machine 105. Long racks 203 are provided on both sides of the rotating motor 201, and fixed components 500 are provided on both sides of the vertical frame. When the long rack 203 passes through the fixed component 500, the cutting part is automatically clamped and limited. After the cutting is completed, the fixed component 500 releases the clamping limit on the cut metal pipe.

[0043] During the cutting process of the metal pipe, a large amount of heat is generated on the surface of the metal pipe. When taking the cut metal pipe, it is easy to cause burns to the operators. Therefore, a through hole 103 is provided on the surface of the machine platform 100 near the lower part of the cutting machine 105, and a collection box 104 is provided below the machine platform 100. The cut metal pipe falls into the interior of the collection box 104 through the through hole 103 for collection. By providing the through hole 103 on the surface of the machine platform 100, when the metal pipe is cut, when the moving seat 200 moves to feed the metal pipe for further cutting operation, the fixing component 500 releases the clamping limit on the cut metal pipe, and the metal pipe falls to the through hole 103 under the action of gravity, and thus is automatically collected inside the collection box 104, avoiding burns caused by operators taking the cut metal pipe and reducing the occurrence of safety hazards.

[0044] Considering that when the metal pipe is relatively long, under the action of gravity, the cutting end of the metal pipe is prone to bending, resulting in an uneven cutting surface when the cutting machine 105 cuts the end of the metal pipe, and requiring operators to perform secondary cutting processing, resulting in low production efficiency. Therefore, an electric telescopic rod 106 is provided on the surface of the machine platform 100 near the vertical frame side, and a rotating roller 107 is provided at the end of the electric telescopic rod 106. The top of the rotating roller 107 is in contact with the bottom of the metal pipe clamped inside the clamping component 300. When clamping the end of the metal pipe through the clamping component 300, control the end of the electric telescopic rod 106 to drive the rotating roller 107 to move in the vertical direction until the rotating roller 107 moves to be in contact with the bottom of the metal pipe, making the central axis of the metal pipe horizontal. When the position adjustment of the metal pipe is completed, control the cutting machine 105 to move down to cut the metal pipe, thereby ensuring the flatness of the cutting surface, avoiding secondary processing caused by the offset of the cutting surface, and thus improving the processing efficiency.

[0045] Considering that when cutting a metal pipe, since the surface of the metal pipe is arc-shaped, it is easy for the metal pipe to be unstable during cutting due to manual pressing, resulting in deviation of the cutting size and waste of the metal pipe material. Therefore, the clamping assembly 300 includes a sealing box 301 provided on the surface of the moving seat 200. A first motor 302 is provided at the end of the sealing box 301. The first motor 302 penetrates the inside of the sealing box 301 and a main gear 303 is provided at its end. A secondary gear 304 is provided on the side of the main gear 303. The secondary gears 304 are arranged in an array. A lead screw 305 is provided on the inner wall of the secondary gear 304. Clamping plates 306 are provided on the surface of the lead screw 305. When the main gear 303 rotates to drive the secondary gear 304 to mesh and rotate, the clamping plates 306 provided on the surface of the lead screw 305 move relative to each other to clamp the metal pipe. Move the metal pipe to be cut to the end of the sealing box 301, control the output shaft of the first motor 302 to drive the main gear 303 to rotate. When the main gear 303 rotates, it drives the secondary gear 304 to mesh and rotate. When the secondary gear 304 rotates, the lead screw 305 provided on its surface rotates coaxially. When the lead screw 305 rotates, the clamping plate 306 moves on the surface of the lead screw 305 to clamp and fix the end of the metal pipe, thereby avoiding deviation of the cutting size caused by the sliding of the metal pipe during the cutting process of the metal pipe, and thus avoiding waste of the pipe material.

[0046] When cutting a metal pipe, due to different requirements, when angle cutting of a batch of metal pipes is required, the operator needs to frequently adjust the cutting angle of the metal pipe. In order to facilitate quick adjustment of the cutting angle, therefore, the adjustment assembly 400 includes a chassis 401 provided on the top of the cutting machine 105. A rotating rod penetrates the chassis 401 on the top of the cutting machine 105. A cylinder 405 is provided on the top of the chassis 401. Control the piston rod at the end of the cylinder 405 to drive the cutting machine 105 to move downward in the vertical direction. A second motor 402 is provided on one side of the chassis 401. The output end of the second motor 402 penetrates the chassis 401 and a worm 403 is provided at its end. A turbine 404 is provided on one side of the worm 403. The turbine 404 is clamped on the surface of the rotating rod. Control the output end of the second motor 402 to drive the worm 403 to rotate to make the turbine 404 mesh and rotate. The rotation of the turbine 404 adjusts the cutting angle of the cutting machine 105. When cutting the metal pipe is required, control the output shaft of the second motor 402 to rotate. The output shaft of the second motor 402 drives the worm 403 to rotate coaxially. When the worm 403 rotates, it drives the turbine 404 to mesh and rotate. By drawing angle lines on the top of the cutting machine 105 and observing the angle of rotation of the cutting machine 105, when the cutting machine 105 rotates to the set angle, the output shaft of the second motor 402 stops rotating. Since the worm 403 has self-locking property, the cutting angle of the cutting machine 105 is fixed. Control the output end of the cylinder 405 to drive the chassis 401 to move downward in the vertical direction. The chassis 401 drives the cutting machine 105 to perform angle cutting on the metal pipe during the movement, thereby realizing rapid batch angle cutting of the metal pipe and improving the cutting processing efficiency.

[0047] Considering that during the cutting process, when the metal pipe is cut and broken, it is easy to pop out and hit the nearby operators under the extrusion force of the blade of the cutting machine 105, posing a huge safety hazard. Therefore, the fixing component 500 includes support columns arranged on both sides of the surface of the machine table 100. Column barrels 501 are provided on the surfaces of the support columns. An extrusion plate 502 is slidably arranged on the inner wall of the column barrel 501. A compression spring 503 is arranged between the column barrel 501 and the extrusion plate 502. A compression block 504 is provided at the bottom of the extrusion plate 502. The compression block 504 penetrates through the bottom of the column barrel 501 to the outside. In the natural state, the extrusion plate 502 is away from the surface of the metal pipe to be cut under the action of the compression spring 503. By pressing the compression block 504, the extrusion plate 502 is driven to slide on the inner wall of the column barrel 501 to clamp and fix the cutting end of the metal pipe. During the processing, by squeezing the compression block 504, the extrusion plate 502 provided at the end of the compression block 504 slides on the inner wall of the column barrel 501. When the extrusion plate 502 moves relatively to the end of the metal pipe, the extrusion plate 502 clamps and fixes the end of the metal pipe, thereby avoiding the safety hazard caused by the metal pipe popping out during processing and improving the safety of the operation.

[0048] When cutting a metal pipe, when the cutting operation is completed, due to the friction of the cutting tool of the cutting machine 105 on the cutting part, the surface temperature of the cutting material is relatively high. When taking and collecting the cut metal pipe, it is easy to cause burns to the operating personnel. Therefore, a gear shaft 505 is provided on one side of the column. An eccentric wheel 506 is provided on the side of the gear shaft 505 close to the inner wall of the column. A rotating gear 507 is provided at the end of the eccentric wheel 506. The gear shaft 505 drives the rotating gear 507 to rotate meshingly. When the rotating gear 507 rotates, it drives the eccentric wheel 506 to rotate coaxially. When the moving seat 200 drives the long rack 203 to move horizontally, the long rack 203 drives the gear shaft 505 to rotate one week. When performing the cutting operation, by controlling the output end of the rotating motor 201 to drive the half gear 202 to rotate, one rotation of the half gear 202 is the length that the metal pipe needs to be cut. When the moving seat 200 moves, it drives the long rack 203 to move. When the long rack 203 moves, it drives the gear shaft 505 to rotate meshingly. The moving path of the long rack 203 drives the gear shaft 505 to rotate one week. When the gear shaft 505 rotates, it drives the rotating gear 507 to rotate meshingly. When the rotating gear 507 rotates, it causes the eccentric wheel 506 to rotate to squeeze the end of the compression block 504, so that the compression block 504 pushes the pressing plate 502 to move relatively to clamp and fix the metal pipe. Control the cutting machine 105 to move down to cut the metal pipe. Since the pressing plate 502 limits the metal pipe at the cutting part, the metal pipe is prevented from popping out. When the cutting is completed, control the cutting machine 105 to move away from the cutting position. When the output end of the rotating motor 201 drives the half gear 202 to rotate, the moving seat 200 moves to feed and cut the metal pipe. During the process of the moving seat 200 driving the long rack 203 to move, the gear shaft 505 drives the rotating gear 507 to rotate meshingly, and at the same time the eccentric wheel 506 rotates coaxially with the rotating gear 507. While the eccentric wheel 506 rotates, the pressure on the compression block 504 gradually disappears, and the pressing plate 502 is reset under the action of the compression spring 503, so that the clamping force on the cut metal pipe disappears, and the metal pipe falls due to gravity and enters the collection box 104 through the through hole 103 for automatic collection.

[0049] The second object of the present invention is to provide a processing method for a metal pipe cutting device, including the metal pipe cutting device in any one of the above, and including the following steps:

[0050] S1. Move the metal pipe to be cut to the end of the sealing box 301, control the output shaft of the first motor 302 to drive the main gear 303 to rotate. When the main gear 303 rotates, it drives the driven gear 304 to rotate meshingly. When the driven gear 304 rotates, the lead screw 305 provided on its surface rotates coaxially. When the lead screw 305 rotates, the clamping plate 306 moves on the surface of the lead screw 305 to clamp and fix the end of the metal pipe;

[0051] S2. Control the rotation of the output shaft of the second motor 402. The output shaft of the second motor 402 drives the coaxial rotation of the worm 403. When the worm 403 rotates, it drives the meshing rotation of the turbine 404. By drawing angular lines on the top of the cutting machine 105 and observing the rotation angle of the cutting machine 105, when the cutting machine 105 rotates to the set angle, the output shaft of the second motor 402 stops rotating. Due to the self-locking property of the worm 403, the cutting angle of the cutting machine 105 is fixed. Control the output end of the cylinder 405 to drive the chassis 401 to move downward in the vertical direction. During the movement of the chassis 401, it drives the cutting machine 105 to perform angular cutting on the metal pipe.

[0052] S3. Control the output end of the rotation motor 201 to drive the rotation of the half gear 202. One rotation of the half gear 202 is the length that the metal pipe needs to be cut. When the moving seat 200 moves, it drives the long rack 203 to move. When the long rack 203 moves, it drives the meshing rotation of the gear shaft 505. The moving path of the long rack 203 drives the gear shaft 505 to rotate one week. When the gear shaft 505 rotates, it drives the meshing rotation of the rotating gear 507. When the rotating gear 507 rotates, it causes the eccentric wheel 506 to rotate to squeeze the end of the compression block 504, so that the compression block 504 pushes the extrusion plate 502 to move relatively to clamp and fix the metal pipe. Control the cutting machine 105 to move downward to cut the metal pipe. Since the extrusion plate 502 limits the metal pipe at the cutting position, the cut metal pipe is prevented from popping out. When the cutting is completed, control the cutting machine 105 to move away from the cutting position. When the output end of the rotation motor 201 drives the half gear 202 to rotate, the moving seat 200 moves to perform feeding cutting on the metal pipe. During the process of the moving seat 200 driving the long rack 203 to move, the gear shaft 505 drives the meshing rotation of the rotating gear 507. At the same time, the eccentric wheel 506 rotates coaxially with the rotating gear 507. While the eccentric wheel 506 rotates, the pressure on the compression block 504 gradually disappears, and the extrusion plate 502 is reset under the action of the compression spring 503, so that the clamping force on the cut metal pipe disappears, and the metal pipe falls due to gravity and enters the collection box 104 through the through hole 103 for automatic collection.

[0053] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention and are not used to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of the present invention claimed is defined by the appended claims and their equivalents.
