Description

Technical Field

[0001] The invention belongs to the technical field of metal processing, in particular to a pipe metal processing and cutting machine. Background Art

[0002] Tubular metals, as the name implies, refer to metal materials used to manufacture various pipes and tubular structures. These materials are widely used in many fields, including but not limited to construction, energy, transportation, chemical industry, machinery manufacturing, etc. Tubular metals mainly include various metal pipes. In actual use, due to the long length of the metal pipe, it needs to be cut when used. At this time, a metal processing cutting machine will be used to assist the cutting process.

[0003] Conventional metal pipe cutting machines mainly include a workbench, a cutting device and a clamping device. When in use, the clamping assembly is first used to clamp the metal pipe. After the clamping is completed, the cutting machine is operated to move down to realize the cutting process of the metal pipe. However, in the cutting process of the metal pipe, multiple cuttings are performed. In the prior art, the clamping assembly needs to be manually operated to loosen and clamp each time cutting, and the entire operation process is extremely cumbersome.

[0004] During the cutting process of metal pipes, since the metal pipes need to be cut in a circular manner, the clamping components need to be frequently loosened and the pipes need to be rotated in order to achieve the circular cutting process on the outer side of the pipes. The overall cutting efficiency is low and needs to be improved urgently. Summary of the invention

[0005] The object of the present invention is to provide a pipe metal processing and cutting machine to solve the problems raised in the above background technology.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a pipe metal processing and cutting machine, comprising a workbench, a frame is fixedly installed in the middle of the top of the workbench, a top plate is fixedly installed on the top of the frame, and adjustment guide rails are fixedly installed on the left and right sides of the top plate, a cylinder is fixedly installed in the middle of the bottom end of the top plate, and a movable frame is fixedly installed on the output end of the cylinder, and adjustment components are installed at the top of the movable frame near the four corners, and the bottom end of the adjustment component is movably connected with the adjustment guide rail, and an extension rod is fixedly installed at the bottom end of the adjustment component, and linkage plates are provided at the top of the workbench near the left and right sides, and the top of the linkage plate is connected to the bottom end of the extension rod, and an extension seat is fixedly installed on the rear side of the bottom end of the movable frame, and a blade fixing seat is fixedly installed on the front side of the bottom end of the movable frame, and a circular saw blade is movably connected inside the blade fixing seat, and a motor is fixedly connected to the bottom end of the extension seat, and the output end of the motor is connected to the middle of the circular saw blade, and an auxiliary cutting assembly is fixedly installed in the middle of the front end of the blade fixing seat.

[0007] Before using the device, prepare the metal round pipe to be cut and place it on the workbench and between two clamps, and connect the rear end of the three-way valve to the external water pump to ensure the normal injection of external cooling water.

[0008] As a further technical solution of the present invention, a first fixed seat is fixedly installed at a position near the four corners at the top of the movable frame, the end of the first fixed seat away from the movable frame is movably connected to a connecting rod via a rotating shaft, and the end of the connecting rod away from the first fixed seat is movably connected to a second fixed seat via a rotating shaft.

[0009] As a further technical solution of the present invention, a guide block is fixedly installed on the top of the second fixing seat, the guide block is movably connected to the adjustment guide rail, and one side of the guide block is fixedly connected to the extension rod.

[0010] When cutting a metal round tube, the motor can be turned on to drive the circular saw blade to rotate, and the cylinder can be turned on and controlled to extend. At this time, the cylinder can drive the movable frame to move downward as a whole, and drive the circular saw blade at its bottom to move downward as a whole, until the outer side surface of the circular saw blade contacts the outer side surface of the metal tube, and the metal tube cutting process is carried out.

[0011] As a further technical solution of the present invention, an electric push rod is fixedly installed in the middle of the two linkage plates relatively close to one end, a clamping plate is fixedly installed at the output end of the electric push rod, and balls are movably installed on the front and rear sides of the two clamping plates relatively close to one end.

[0012] At the same time, when the movable frame moves downward, the two connecting rods are deflected in the direction of approaching each other, and a pulling force is applied to the two guide blocks. At this time, the two guide blocks can be relatively adjusted to move the guide rails, that is, the left and right guide blocks are relatively close to each other. At this time, the two extension rods can be driven relatively close to each other synchronously, and the two linkage plates at the bottom are driven relatively close to each other. At this time, the two clamping plates are displaced in the direction of approaching the circular tube until the outer side surfaces of the multiple ball bearings contact the outer side surfaces of the circular tube. At the same time, the distance between the linkage plate and the clamping plate can be controlled by turning on the electric push rod to adapt to circular tubes of different diameters, ensuring that the clamping can be just completed when the circular tube is cut, and during the cutting process, that is, when the circular saw blade moves downward, the distance between the linkage plate and the clamping plate is gradually reduced to ensure that the best clamping state is always maintained to meet the clamping requirements; After the cutting is completed, the cylinder can be controlled to shorten, which can drive the movable frame to move upward. At this time, the circular saw blade moves upward accordingly, and finally drives the two clamps to move away from each other, automatically releasing the clamping process of the metal pipe.

[0013] By utilizing the automatic downward movement of the circular saw blade when cutting the round tube, and through the cooperation between the movable frame, the adjustment component and the linkage plate, the clamping process can be completed synchronously during cutting, that is, the cutting and clamping processes are completed at the same time, and the clamping process is automatically released after the cutting is completed, effectively avoiding the problem of frequent clamping and releasing operations of the clamping device when performing multi-segment cutting in traditional devices. The fixing and loosening of the round tube can be automatically achieved without operating the clamping of the round tube, thereby significantly improving the cutting efficiency.

[0014] As a further technical solution of the present invention, the auxiliary cutting assembly includes a liquid storage tank, the rear end of the liquid storage tank is connected to the middle part of the circular saw blade, the front end of the liquid storage tank is fixedly connected to a liquid injection valve, the front end of the liquid injection valve is movably installed with a three-way valve, the liquid injection valve and the three-way valve are connected, the front end of the three-way valve is connected to an external water pump, the top of the three-way valve is fixedly connected to a high-pressure water spray pipe, the output end of the high-pressure water spray pipe passes through the front end of the movable frame and is located on one side of the circular saw blade, and the liquid injection valve rotates relative to the three-way valve.

[0015] At the same time, during the cutting process, that is, when the circular saw blade cuts the metal pipe, the external water pump can be kept injecting high-pressure water into the inside of the three-way valve, and the valve at the top of the three-way valve can be opened. At this time, high-pressure water will enter the inside of the three-way valve and be discharged through the high-pressure water spray pipe at the top of the three-way valve. The high-pressure water discharged through the high-pressure water spray pipe will then enter the vicinity of the circular saw blade, and the high-pressure water will directly cool the cutting area and remove debris.

[0016] By directly utilizing the high-pressure water input from the outside, the device can directly introduce high-pressure water to the cutting position when cutting metal pipes. The high-speed flowing water directly takes away the cutting heat and the cutting debris at the same time. The whole process can be completed automatically. At the same time, the cooling position can automatically rise and fall with the cutting position to provide the best cooling effect and further improve the cutting efficiency.

[0017] As a further technical solution of the present invention, the outer side surface of the liquid storage tank is fixedly connected with an adjusting tube at an equal angle, and the inside of the adjusting tube is movably sleeved with a piston plate, and the piston plate moves up and down relative to the adjusting tube.

[0018] As a further technical solution of the present invention, one end of the piston plate away from the liquid storage tank is fixedly connected to a piston rod, and one end of the piston rod away from the piston plate passes through one end of the regulating tube and is fixedly connected to a rubber block.

[0019] As a further technical solution of the present invention, the outer side surface of the piston rod is movably sleeved with a limit spring, and the upper and lower ends of the limit spring are respectively connected to one end of the piston plate and one end of the inner cavity of the regulating tube.

[0020] At the same time, during the cutting process of the metal pipe, the valve at the rear end of the three-way valve can be opened to inject high-pressure water into the injection valve, so that the high-pressure water enters the interior of the liquid storage tank. At this time, the high-pressure water then enters the interior of multiple adjusting tubes and exerts a force on the piston plate, causing the piston plate and the piston rod to move toward the outer side. At this time, the limit spring is compressed and the rubber block is driven to move away from the adjusting tube until the rubber block contacts the outer side of the metal pipe. At this time, the rotation of the circular saw blade can synchronously drive the liquid storage tank to rotate, and drive the rubber block on the outer side to rotate circumferentially, and drive the metal pipe to rotate through friction, thereby assisting in completing the cutting process.

[0021] By utilizing high-pressure water input from the outside and directing it into the interior of the liquid storage tank, the amount of high-pressure water input is controlled to ensure that the rubber block contacts metal pipes of different diameters, and cooperates with the rotation process during cutting to actively complete the autonomous rotation process of the metal pipe, thereby avoiding the problem of traditional devices requiring frequent operation of the clamping device and rotation of the pipe during cutting. The entire process can be completed automatically, effectively shortening the operation time and improving the overall cutting efficiency.

[0022] The beneficial effects of the present invention are as follows: (1) The present invention utilizes the automatic downward movement of the circular saw blade when cutting the round tube, and through the cooperation between the movable frame, the adjustment component and the linkage plate, the clamping process can be completed synchronously during the cutting process, that is, the cutting and clamping processes are completed at the same time, and the clamping process is automatically released after the cutting is completed, effectively avoiding the problem of frequent clamping and loosening operations of the clamping device when performing multi-stage cutting in traditional devices. The round tube can be automatically fixed and loosened without the need to operate the clamping of the round tube, thereby significantly improving the cutting efficiency.

[0023] (2) The present invention utilizes high-pressure water input from the outside and guides the high-pressure water into the interior of the liquid storage tank. By controlling the amount of high-pressure water input, the rubber block is ensured to contact the metal pipes of different diameters. The metal pipes are actively rotated in coordination with the rotation process during cutting. This avoids the problem of traditional devices requiring frequent operation of the clamping device and rotation of the pipe during cutting. The entire process can be completed automatically, effectively shortening the operation time and improving the overall cutting efficiency.

[0024] (3) The present invention directly utilizes high-pressure water input from the outside, so that when the device is cutting a metal pipe, the high-pressure water can be directly introduced into the cutting position, and the cutting heat is directly taken away by the high-speed flowing water, and the cutting debris is taken away simultaneously. The whole process can be completed automatically, and the cooling position can be automatically raised and lowered with the cutting position to provide the best cooling effect, thereby further improving the cutting efficiency.

[0029] Before using the device, the metal round pipe to be cut needs to be prepared and placed on the workbench 1, and placed between the two clamping plates 11, and the rear end of the three-way valve 13 is connected to the external water pump to ensure the normal injection of external cooling water.

[0030] like Figure 1 and Figure 2 as well as Figure 4 and Figure 5 As shown, a first fixed seat 701 is fixedly installed at the top of the movable frame 6 near the four corners, the end of the first fixed seat 701 away from the movable frame 6 is movably connected to a connecting rod 703 through a rotating shaft, the end of the connecting rod 703 away from the first fixed seat 701 is movably connected to a second fixed seat 702 through a rotating shaft, and a guide block 704 is fixedly installed on the top of the second fixed seat 702, the guide block 704 is movably engaged with the adjusting guide rail 4, and one side of the guide block 704 is fixedly connected to the extension rod 8.

[0031] When cutting a metal round tube, the motor 16 can be turned on to drive the circular saw blade 18 to rotate, and the cylinder 5 can be turned on and controlled to extend. At this time, the cylinder 5 can drive the movable frame 6 to move downward as a whole, and drive the circular saw blade 18 at its bottom end to move downward as a whole, until the outer side surface of the circular saw blade 18 contacts the outer side surface of the metal tube, and the metal tube cutting process is carried out.

[0032] like Figure 1 and Figure 2 as well as Figure 4 As shown, an electric push rod 10 is fixedly installed in the middle of the two linkage plates 9 relatively close to one end, a clamping plate 11 is fixedly installed at the output end of the electric push rod 10, and balls 12 are movably installed on the front and rear sides of the two clamping plates 11 relatively close to one end.

[0033] Embodiment: When the movable frame 6 moves downward, the two connecting rods 703 deflect in the direction of approaching each other, and apply tension to the two guide blocks 704. At this time, the two guide blocks 704 can be displaced relative to the adjusting guide rail 4, that is, the left and right guide blocks 704 are relatively close to each other. At this time, the two extension rods 8 can be driven relatively close to each other synchronously, and the two linkage plates 9 at the bottom are driven relatively close to each other. At this time, the two clamping plates 11 are displaced in the direction of approaching the circular tube until the outer side surfaces of the multiple balls 12 contact the outer side surfaces of the circular tube. At the same time, the distance between the linkage plate 9 and the clamping plate 11 can be controlled by turning on the electric push rod 10 to adapt to circular tubes of different diameters, ensuring that the clamping can be just completed when the circular tube is cut, and during the cutting process, that is, when the circular saw blade 18 moves downward, the distance between the linkage plate 9 and the clamping plate 11 is gradually reduced to ensure that the best clamping state is always maintained to meet the clamping requirements; After the cutting is completed, the cylinder 5 can be controlled to shorten, and the movable frame 6 can be driven to move upward. At this time, the circular saw blade 18 moves upward accordingly, and finally drives the two clamping plates 11 away from each other, automatically releasing the clamping process of the metal pipe.

[0034] By utilizing the automatic downward movement of the circular saw blade 18 when cutting the round tube, and through the cooperation between the movable frame 6, the adjustment component 7 and the linkage plate 9, the clamping process can be completed synchronously when cutting, that is, the cutting and clamping processes are completed at the same time, and the clamping process is automatically released after the cutting is completed, effectively avoiding the problem of frequent clamping and loosening operations of the clamping device when performing multi-segment cutting in traditional devices. The fixing and loosening of the round tube can be automatically achieved without the need to operate the clamping of the round tube, thereby significantly improving the cutting efficiency.

[0035] like Figure 1 and Figure 6 and with 8 and Fig. 9 As shown, the auxiliary cutting assembly 19 includes a liquid storage tank 191, the rear end of the liquid storage tank 191 is connected to the middle part of the circular saw blade 18, the front end of the liquid storage tank 191 is fixedly connected to a liquid injection valve 192, the front end of the liquid injection valve 192 is movably installed with a three-way valve 13, the liquid injection valve 192 and the three-way valve 13 are connected, the front end of the three-way valve 13 is connected to an external water pump, the top of the three-way valve 13 is fixedly connected to a high-pressure water spray pipe 14, the output end of the high-pressure water spray pipe 14 passes through the front end of the movable frame 6 and is located on one side of the circular saw blade 18, and the liquid injection valve 192 rotates relative to the three-way valve 13.

[0036] At the same time, during the cutting process, that is, when the circular saw blade 18 cuts the metal pipe, the external water pump can be kept injecting high-pressure water into the three-way valve 13, and the valve at the top of the three-way valve 13 can be opened. At this time, the high-pressure water enters the interior of the three-way valve 13 and is discharged through the high-pressure water spray pipe 14 at the top thereof. The high-pressure water discharged through the high-pressure water spray pipe 14 then enters the vicinity of the circular saw blade 18, and the high-pressure water is used to directly cool the cutting area and remove debris.

[0037] By directly utilizing the high-pressure water input from the outside, the device can directly introduce high-pressure water to the cutting position when cutting metal pipes. The high-speed flowing water directly takes away the cutting heat and the cutting debris at the same time. The whole process can be completed automatically. At the same time, the cooling position can automatically rise and fall with the cutting position to provide the best cooling effect and further improve the cutting efficiency.

[0038] like Figure 8 and Fig. 9 As shown, the outer side surface of the liquid storage tank 191 is fixedly connected to the regulating tube 193 at an equal angle, and the interior of the regulating tube 193 is movably sleeved with a piston plate 194, which moves up and down relative to the regulating tube 193. The end of the piston plate 194 away from the liquid storage tank 191 is fixedly connected to a piston rod 195, and the end of the piston rod 195 away from the piston plate 194 passes through one end of the regulating tube 193 and is fixedly connected to a rubber block 197. The outer side surface of the piston rod 195 is movably sleeved with a limit spring 196, and the upper and lower ends of the limit spring 196 are respectively connected to one end of the piston plate 194 and one end of the inner cavity of the regulating tube 193.

[0039] Embodiment: At the same time, during the cutting process of the metal pipe, the valve at the rear end of the three-way valve 13 can be opened to inject high-pressure water into the interior of the injection valve 192, so that the high-pressure water enters the interior of the liquid storage tank 191. At this time, the high-pressure water then enters the interior of the multiple adjusting tubes 193 and applies a force to the piston plate 194, so that the piston plate 194 and the piston rod 195 are displaced toward the outer side. At this time, the limit spring 196 is compressed and drives the rubber block 197 to displace in the direction away from the adjusting tube 193 until the rubber block 197 contacts the outer side of the metal pipe. At this time, the rotation of the circular saw blade 18 can synchronously drive the liquid storage tank 191 to rotate, and drive the rubber block 197 on the outer side to rotate circumferentially, and drive the metal pipe to rotate through friction, thereby assisting in completing the cutting process.

[0040] By utilizing high-pressure water input from the outside and directing the high-pressure water into the interior of the liquid storage tank 191, by controlling the amount of high-pressure water input, it is ensured that the rubber block 197 contacts the metal pipes of different diameters, and cooperates with the rotation process during cutting to actively complete the autonomous rotation process of the metal pipe, thereby avoiding the problem of traditional devices requiring frequent operation of the clamping device and rotation of the pipe during cutting. The entire process can be completed automatically, effectively shortening the operation time and improving the overall cutting efficiency.

[0041] Working principle and usage process: Before use, prepare the metal round pipe to be cut and place it on the workbench 1, and place it between the two clamping plates 11, and connect the rear end of the three-way valve 13 to the external water pump to ensure the normal injection of external cooling water; When cutting a metal round tube, the motor 16 can be turned on to drive the circular saw blade 18 to rotate, and the cylinder 5 can be turned on and controlled to extend. At this time, the cylinder 5 can drive the movable frame 6 to move downward as a whole, and drive the circular saw blade 18 at its bottom end to move downward as a whole, until the outer side surface of the circular saw blade 18 contacts the outer side surface of the metal tube, and the metal tube cutting process is carried out; At the same time, when the movable frame 6 moves downward, the two connecting rods 703 are deflected in the direction of approaching each other, and a pulling force is applied to the two guide blocks 704. At this time, the two guide blocks 704 can be relatively adjusted. The guide rail 4 moves, that is, the left and right guide blocks 704 are relatively close to each other. At this time, the two extension rods 8 can be driven relatively close to each other synchronously, and the two linkage plates 9 at the bottom are driven relatively close to each other. At this time, the two clamping plates 11 are displaced in the direction of approaching the circular tube until the outer side surfaces of the plurality of balls 12 contact the outer side surfaces of the circular tube. At the same time, the distance between the linkage plate 9 and the clamping plate 11 can be controlled by turning on the electric push rod 10 to adapt to circular tubes of different diameters, ensuring that the clamping can be just completed when the circular tube is cut, and during the cutting process, that is, when the circular saw blade 18 moves downward, the distance between the linkage plate 9 and the clamping plate 11 is gradually reduced to ensure that the best clamping state is always maintained to meet the clamping requirements; After the cutting is completed, the cylinder 5 can be controlled to shorten, so as to drive the movable frame 6 to move upward, and the circular saw blade 18 moves upward accordingly, and finally drives the two clamping plates 11 to move away from each other, automatically releasing the clamping process of the metal pipe; Meanwhile, during the cutting process, that is, when the circular saw blade 18 is cutting the metal pipe, the external water pump can be kept injecting high-pressure water into the three-way valve 13, and the valve at the top of the three-way valve 13 can be opened. At this time, the high-pressure water then enters the interior of the three-way valve 13 and is discharged through the high-pressure water spraying pipe 14 at the top thereof. The high-pressure water discharged through the high-pressure water spraying pipe 14 then enters the vicinity of the circular saw blade 18, and the high-pressure water is used to directly cool the cutting area and remove debris. At the same time, during the cutting process of the metal pipe, the valve at the rear end of the three-way valve 13 can be opened to inject high-pressure water into the interior of the injection valve 192, so that the high-pressure water enters the interior of the liquid storage tank 191. At this time, the high-pressure water then enters the interior of the multiple adjusting tubes 193 and exerts a force on the piston plate 194, so that the piston plate 194 and the piston rod 195 are displaced toward the outer side. At this time, the limit spring 196 is compressed and drives the rubber block 197 to displace in the direction away from the adjusting tube 193 until the rubber block 197 contacts the outer side of the metal pipe. At this time, the rotation of the circular saw blade 18 can synchronously drive the liquid storage tank 191 to rotate, and drive the rubber block 197 on the outer side to rotate circumferentially, and drive the metal pipe to rotate through friction, thereby assisting in completing the cutting process.
