Description

TECHNICAL FIELD

[0001] The application relates to the technical field of laser cutting, and particularly relates to a cutting equipment for metal pipe machining. BACKGROUND

[0002] The laser cutting machine is a machine using laser cutting, and the working principle is that laser emitted from a laser is focused into a high-power density laser beam through an optical system, and the laser beam is irradiated to a workpiece surface, so that the workpiece reaches a melting point or a boiling point, and a high-speed airflow coaxial with the laser beam blows away the melted or burned material, so that cutting is realized.

[0003] The laser cutting machine for metal pipe machining disclosed in Patent No. CN118699579A is provided with a sliding plate, a moving pipe rotating mechanism and a laser cutting mechanism, a pipe supporting assembly is connected with the metal pipe, and then the sliding plate and the metal pipe are driven to move by a driving assembly and a moving assembly. When the pre-cutting position of the metal pipe reaches the position directly below the laser cutting mechanism, the metal pipe is cut by starting the laser cutter. Since the driving assembly drives the pipe supporting assembly and the metal pipe to rotate continuously, the metal pipe is cut by the laser cutting mechanism, and the cutting efficiency is improved. However, in actual use, when the laser cutting machine cuts the metal pipe, the metal round pipe can be rotated for sufficient cutting. When the metal square pipe is cut, the rotating range of the metal square pipe changes continuously after rotation, the distance between the metal square pipe and the laser cutter changes continuously, the laser cutter cuts by the laser beam, and in order to ensure that the laser beam can completely cut the square pipe, the focal length of the laser beam on the laser cutter needs to be adjusted continuously. The distance changes continuously during the rotation of the metal square pipe, and the adjustment is relatively complicated. It is difficult to be applied to the cutting work of different types of metal pipes, and there is a certain use defect.

[0027] By adopting the above technical scheme, it is convenient to rotate the pipe and cut the pipe.

[0028] Compared with the prior art, the cutting equipment for metal pipe machining has the cutting assembly arranged on one side of the top of the base, so that the square pipe can be rotated when cutting the square pipe, the distance between the laser cutting head and the square pipe is always unchanged, the cutting effect is avoided from being affected, the focal length of the laser cutting head does not need to be adjusted all the time, square pipes and round pipes of different sizes can be conveniently cut, and the practicability is improved.

[0029] 1、In the process of cutting the pipe, the pipe is fixed by the fixing assembly, then the driving motor is started to drive the screw rod to rotate, so that the movable seat can be moved, the movement of the movable seat can make the roller contact one end of the pipe, whether it is a square pipe or a round pipe, the roller rotates at one end of the pipe with the movement of the movable seat, the moving frame can be lifted, then the universal wheel can contact the pipe, the moving frame moves on the supporting rod to limit the movement, and the movable rod can slide on the L-shaped frame to stretch the extension spring, so that the laser cutting head can be lifted, then the universal wheel moves to the top of the pipe with the movement of the movable seat, if the round pipe is cut, the round pipe can be directly rotated to be cut by the laser cutting head, if the square pipe is cut, the universal wheel can be driven to rotate with the rotation of the square pipe, if the universal wheel is lifted and moves up with the rotation of the square pipe, the laser cutting head can be driven to move up under the action of the extension spring, and if the universal wheel moves down with the rotation of the square pipe, the laser cutting head moves down under the elastic action of the extension spring, so that the distance between the laser cutting head and the square pipe does not change, the square pipe can be rotated and cut, the cutting efficiency is improved, the square pipe can be rotated when cutting the square pipe through the cutting assembly, the distance between the laser cutting head and the square pipe is always unchanged, the cutting effect is avoided from being affected, the focal length of the laser cutting head does not need to be adjusted all the time, square pipes and round pipes of different sizes can be conveniently cut, and the practicability is improved.

[0030] 2. During the cutting process, the square tube rotates clockwise. As the tube rotates from a straight position to an inclined position, it pushes the casters upward, causing the moving frame to move upward. This moves the sliding rod, causing the piston to move upward within the cylinder. At this time, the one-way valve inside the air inlet opens and the one-way valve inside the air outlet closes, allowing air to be drawn into the cylinder. As the square tube gradually rotates back to a straight position, the casters move downward, causing the moving frame to move the sliding rod downward. The piston then moves downward within the cylinder, at which point the one-way valve inside the air inlet closes and the one-way valve inside the air outlet opens. Air inside the cylinder can be forced into the exhaust pipe, and then the air is ejected through the telescopic pipe and the jet pipe. The telescopic pipe is made of high-temperature resistant material. When the square tube is rotated from tilt to straight, it will be cut at the bend of the square tube. The bend of the square tube is thicker, and the jet pipe can cool it down by spraying air, which improves the cutting quality and prevents the heat from being difficult to dissipate due to the thickness of the bend of the square tube. In addition, the nozzle diameter of the jet pipe is small, and the airflow from the jet pipe has a certain flow rate. Blowing it towards the bend of the square tube can reduce the adhesion of high-temperature waste residue generated during cutting, thus improving practicality.

[0031] 3. After fixing the pipe and passing it through the rotating cylinder, the hydraulic push rod can be activated to move the moving plate. After the moving plate moves, the two mounting plates can be pulled closer together by the steel wire rope. During the movement, the mounting plates slide on the limit rod and stretch the return spring, so that the two rubber arc plates on the moving rod wrap and clamp the pipe. The rubber arc plates can deform and can be used to fix square and round pipes. Then, the rotating motor can be activated to drive the rotating gear to rotate. The rotating gear can drive the rotating cylinder to rotate through the meshing of the external gear ring, thereby making the pipe rotate. This allows for the rotation and cutting of square or round pipes, improving the cutting efficiency. Attached Figure Description

DETAILED DESCRIPTION

[0042] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0043] Please refer to Figures 1-9 The present application provides a technical solution: a cutting equipment for metal pipe machining, which comprises a base 1, two groups of fixed blocks 101 are symmetrically installed on the top side of the base 1, a screw rod 102 is rotatably connected between the two fixed blocks 101 on one side, a fixed rod 104 is fixedly installed between the two fixed blocks 101 on the other side, a drive motor 103 is fixedly installed on the side of the front left fixed block 101, and the output end of the drive motor 103 is fixedly connected with the screw rod 102 through the fixed block 101;

[0044] It also comprises:

[0045] The cutting assembly 2 is arranged on the top side of the base 1, and the cutting assembly 2 comprises a movable seat 201;

[0046] Fixing component 3 is located on the other side of the top of base 1;

[0047] The movable seat 201 is located on the top side of the base 1. The movable seat 201 is slidably connected to the fixed rod 104 and threadedly connected to the lead screw 102. A fixed frame 202 is fixedly installed on the top of the movable seat 201. An installation cylinder 203 is installed through the upper part of the fixed frame 202, and an L-shaped frame 204 is fixedly installed on the top of the installation cylinder 203.

[0048] Movable rods 205 are symmetrically slidably connected to one side of the inside of the L-shaped frame 204. Movable plates 206 are fixedly installed at the bottom of the two movable rods 205, and laser cutting heads 207 are fixedly installed on one side of the inside of the movable plates 206. Support rods 208 are symmetrically installed on the top of the fixed frame 202, and movable frames 209 are slidably connected to the outside of the two support rods 208.

[0049] Both movable rods 205 are fitted with telescopic springs 210 on their outer upper sides, and the two ends of the two telescopic springs 210 are fixedly connected to the movable frame 209 and the L-shaped frame 204 respectively.

[0050] A support frame 211 is symmetrically installed on one side of the mobile frame 209, and a roller 212 is rotatably connected between the two support frames 211. A caster wheel 213 is rotatably connected to one side of the bottom of the mobile frame 209.

[0051] The bottom surface of the laser cutting head 207 is always higher than the bottom surface of the caster wheel 213.

[0052] Example 1: As Figures 1-5As shown, when cutting the pipe, the pipe is fixed by the fixing assembly 3, then the drive motor 103 can drive the screw rod 102 to rotate, so that the movable seat 201 can be moved, and the movement of the movable seat 201 can make the roller 212 contact one end of the pipe. Whether it is a square tube or a round tube, the roller 212 rotates at one end of the pipe as the movable seat 201 moves, which can lift the moving frame 209, and then the universal wheel 213 can contact the pipe. The moving frame 209 slides on the supporting rod 208 during movement to limit, and the movable rod 205 can slide on the L-shaped frame 204 to stretch the extension spring 210, so that the laser cutting head 207 can be lifted. Then, as the movable seat 201 moves, the universal wheel 213 moves to the top of the pipe. If the round pipe is cut, the round pipe can be directly rotated and cut by the laser cutting head 207. If the square tube is cut, the universal wheel 213 can be driven to rotate during the rotation of the square tube. If the universal wheel 213 is lifted and moves upward during the rotation of the square tube, the laser cutting head 207 can be driven to move upward under the action of the extension spring 210. If the square tube rotates and drives the universal wheel 213 to move downward, the laser cutting head 207 moves downward under the elastic action of the extension spring 210, so that the distance between the laser cutting head 207 and the square tube does not change. The square tube can be rotated and cut to improve the cutting efficiency. Through the cutting assembly 2, the square tube can be rotated during cutting, so that the distance between the laser cutting head 207 and the square tube is always constant, which avoids affecting the cutting effect and does not need to adjust the focal length of the laser cutting head 207 all the time. It is convenient to cut square tubes and round pipes of different sizes, and the practicality is improved.

[0053] The top of the mounting cylinder 203 is fixedly installed with a cylinder body 214 on one side of the L-shaped frame 204, the inside of the cylinder body 214 is slidably connected with a piston 215, the top of the piston 215 is fixedly installed with a sliding rod 216, the top end of the sliding rod 216 is fixedly connected with the moving frame 209, and a through hole is formed in the top side of the cylinder body 214;

[0054] A gas inlet hole 217 is connected through the lower side of one side of the cylinder body 214, a gas outlet pipe 218 is connected through the lower side of the other side of the cylinder body 214, one sides of the inside of the gas inlet hole 217 and the gas outlet pipe 218 are provided with one-way valves, one end of the gas outlet pipe 218 away from the cylinder body 214 is connected through with an extension pipe 219, one end of the extension pipe 219 away from the gas outlet pipe 218 is connected through with a jet pipe 220, the outside of one side of the jet pipe 220 is symmetrically installed with a connecting frame 221, and the two connecting frames 221 are fixedly connected with the movable plate 206.

[0055] Embodiment two: as Figures 3-6As shown, the square tube is rotated clockwise during the cutting process. When the square tube is rotated from flat to inclined, the universal wheel 213 is lifted to move the moving frame 209 upwards. At this time, the sliding rod 216 is moved to move the piston 215 upwards in the cylinder 214. At this time, the one-way valve inside the air inlet hole 217 is opened and the one-way valve inside the air outlet pipe 218 is closed. Air can be sucked into the cylinder 214. Then, the square tube is gradually rotated to flat, the universal wheel 213 is lowered to move the sliding rod 216 downwards. At this time, the piston 215 is lowered in the cylinder 214. At this time, the one-way valve inside the air inlet hole 217 is closed and the one-way valve inside the air outlet pipe 218 is opened. The air inside the cylinder 214 is pushed into the air outlet pipe 218. Then, the air is sprayed through the telescopic pipe 219 and the air jet pipe 220. The telescopic pipe 219 is made of high-temperature resistant material. When the square tube is rotated from inclined to flat, the square tube is cut at the bent corner. The bent corner of the square tube has a large thickness. The air jet pipe 220 can cool and cool the bent corner of the square tube to improve the cutting quality. The bent corner of the square tube has a large thickness and the heat is difficult to dissipate. The diameter of the air jet pipe 220 is small. The airflow sprayed by the air jet pipe 220 has a certain flow rate. The airflow blown to the bent corner of the square tube can reduce the adhesion of high-temperature waste residue generated during cutting, and improve the practicability.

[0056] The fixing assembly 3 comprises a vertical plate 301 fixedly installed on the other side of the top of the base 1, a rotating cylinder 302 rotatably connected to the upper part of the inside of the vertical plate 301, two moving rods 303 symmetrically and slidably connected to one side of the inside of the rotating cylinder 302, rubber arc plates 304 fixedly installed on the sides close to each other of the two moving rods 303, mounting plates 305 fixedly installed on the sides away from each other of the two moving rods 303, limiting rods 306 slidably connected to the inside of the two mounting plates 305, and reset springs 307 sleeved on the outside of the limiting rods 306 and fixedly connected to the limiting rods 306 and the mounting plates 305.

[0057] A U-shaped frame 308 is fixedly installed on the outside of the rotating cylinder 302, a hydraulic push rod 309 is fixedly installed on one side of the U-shaped frame 308, a moving plate 310 is fixedly installed on the movable end of the hydraulic push rod 309, guide rods 311 are symmetrically installed on one side of the moving plate 310, the two guide rods 311 are slidably connected to the U-shaped frame 308, steel wires 312 are symmetrically installed on the two sides of the moving plate 310, and the ends away from the moving plate 310 of the two steel wires 312 are fixedly connected to the two mounting plates 305.

[0058] The other side of the rotating cylinder 302 is fixedly installed with an outer gear ring 313, and the top of the vertical plate 301 is fixedly installed with a rotating motor 314, and the output end of the rotating motor 314 is fixedly installed with a rotating gear 315, and the rotating gear 315 is in meshing connection with the outer gear ring 313.

[0059] Embodiment three: as shown in Figure 1 and Figures 7-9 shown, after fixing the pipe and passing the pipe through the rotating cylinder 302, the hydraulic push rod 309 can be started to drive the moving plate 310 to move, and after the moving plate 310 moves, the two mounting plates 305 can be pulled close to each other by the steel wire rope 312, and the mounting plate 305 slides on the limiting rod 306 and stretches the reset spring 307 during the movement, so that the two rubber arc plates 304 on the moving rod 303 can wrap and clamp the pipe, and the rubber arc plate 304 can be deformed, which can be suitable for fixing square tubes and round tubes, and then the rotating motor 314 can be started to drive the rotating gear 315 to rotate, and the rotating gear 315 can drive the rotating cylinder 302 to rotate through the meshing with the outer gear ring 313, so that the pipe can be rotated, and the square tube or the round tube can be rotated and cut, which improves the cutting efficiency.

[0060] Working principle: when using the metal pipe fitting processing cutting equipment, first, according to Figures 1-9 shown, when cutting the pipe, the pipe is fixed by the fixing assembly 3, and then the drive motor 103 can be started to drive the lead screw 102 to rotate, so that the movable seat 201 can be driven to move, and the roller 212 can be in contact with one end of the pipe through the movement of the movable seat 201, whether it is a square tube or a round tube, the roller 212 can rotate at one end of the pipe during the movement of the movable seat 201, and the moving frame 209 can be lifted, and then the universal wheel 213 can be in contact with the pipe, and the moving frame 209 can slide on the supporting rod 208 during the movement to limit the position, and the movable rod 205 can slide on the L-shaped frame 204, so that the extension spring 210 can be stretched, and then the laser cutting head 207 can be lifted, and then the universal wheel 213 can be moved to the top of the pipe through the movement of the movable seat 201, and if the round pipe is cut, the round pipe can be directly rotated and cut by the laser cutting head 207, and if the square tube is cut, the universal wheel 213 can be driven to rotate during the rotation of the square tube, and if the universal wheel 213 is lifted and moves up during the rotation of the square tube, the laser cutting head 207 can be driven to move up under the action of the extension spring 210, and if the square tube rotates and drives the universal wheel 213 to move down, the laser cutting head 207 can be driven to move down under the elastic action of the extension spring 210, so that the distance between the laser cutting head 207 and the square tube does not change, and the square tube can be rotated and cut, which improves the cutting efficiency.

[0061] During the cutting process, the square tube rotates clockwise. When the square tube rotates from straight to tilted, it can push the caster wheel 213 upward, causing the moving frame 209 to move upward. At this time, it can drive the sliding rod 216 to move, causing the piston 215 to move upward in the cylinder 214. At this time, the one-way valve inside the air inlet 217 opens and the one-way valve inside the air outlet 218 closes, allowing air to be drawn into the cylinder 214. Afterward, when the square tube gradually rotates to a straight position, the caster wheel 213 moves downward, causing the moving frame 209 to drive the sliding rod 216. As the piston 215 moves downwards within the cylinder 214, the one-way valve inside the air inlet 217 closes and the one-way valve inside the air outlet 218 opens, forcing air from inside the cylinder 214 into the outlet 218. The air is then ejected through the telescopic pipe 219 and the jet pipe 220. The telescopic pipe 219 is made of high-temperature resistant material. When the square tube rotates from an inclined position to a straight position, it cuts at the bends. Since the bends are thicker, the jet pipe 220 cools the area, improving cutting quality and preventing... At the bends of the square tubes, the heat is difficult to dissipate due to the greater thickness. Furthermore, the nozzle diameter of the jet pipe 220 is small, and the airflow from the jet pipe 220 has a certain velocity. Blowing this airflow towards the bends of the square tubes reduces the adhesion of high-temperature slag generated during cutting, improving practicality. After fixing the pipe and passing it through the rotating cylinder 302, the hydraulic push rod 309 can be activated to move the moving plate 310. After the moving plate 310 moves, the two mounting plates 305 can be pulled closer together via the steel wire rope 312. During the movement of the mounting plates 305, [they are subject to certain restrictions]. The sliding and stretching of the return spring 307 on the positioning rod 306 causes the two rubber arc plates 304 on the moving rod 303 to wrap and clamp the pipe. The rubber arc plates 304 can deform, which is suitable for fixing square and round pipes. Then, the rotating motor 314 can be started to drive the rotating gear 315 to rotate. The rotating gear 315 can drive the rotating cylinder 302 to rotate through the meshing of the external gear ring 313, thereby making the pipe rotate. This allows for the rotational cutting of square or round pipes, improving the cutting efficiency.
