Description

Technical Field

[0001] The present invention relates to the technical field of cutting machines for processing metal raw materials, and in particular to a cutting machine for processing metal raw materials and a processing method thereof. Background Art

[0002] In the processing of metal raw materials, cutting machines are indispensable equipment, which are used to cut metal plates, pipes, profiles and other raw materials into required sizes and shapes according to design requirements. According to different processing requirements and metal material characteristics, the types and working principles of cutting machines also vary.

[0003] When using the current cutting machines for processing metal raw materials, workers often find that: laser cutting machines are usually used to cut metal pipes. One end of the metal pipe is clamped by a three-jaw chuck, and then the metal pipe is moved to a specified position for cutting. However, the end of the metal pipe away from the three-jaw chuck is usually against the baffle without being limited. Therefore, during the cutting process, the unrestricted end of the metal pipe is prone to move downward under the action of gravity, resulting in an uneven cutting surface. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a cutting machine for processing metal raw materials and a processing method thereof.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: In the first aspect, the present invention provides a cutting machine for processing metal raw materials, including a cutting table, a sliding groove is provided on the cutting table, a mounting plate is slidably connected in the sliding groove, a first motor is fixedly connected to the mounting plate, a three-jaw chuck is fixedly connected to the output shaft of the first motor, a threaded rod is rotatably connected in the sliding groove, the threaded rod is threadedly connected to the mounting plate, a second motor is fixedly connected to the cutting table, the output shaft of the second motor is fixedly connected to the threaded rod, a limiting block is fixedly connected to the cutting table, a cutting gun is fixedly connected to the limiting block, a limiting plate is arranged on the cutting table, a limiting structure is arranged on the limiting plate, the limiting structure is mainly composed of a fixing ring, the fixing ring is fixedly connected to the limiting plate, a rotating ring is rotatably connected to the fixing ring, three return blocks are rotatably connected to the rotating ring, a limiting rod is slidably inserted in the return block, and the limiting rod is rotatably connected to the fixing ring.

[0006] The effects achieved by the above components are as follows: one end of the metal pipe is fixed on the three-jaw chuck, the second motor is started, and the output shaft of the second motor drives the threaded rod to rotate, so that the mounting plate can drive the metal pipe forward. When one end of the metal steel pipe is against the limit plate, the first motor is started, and the output shaft of the first motor drives the three-jaw chuck to rotate, which can then drive the metal steel pipe to rotate, open the cutting gun, and cut the metal pipe. When the metal pipe is against the limit plate, the metal pipe will be stuck in the rotating ring, and then the rotating ring is rotated to drive the three return blocks to move, so that the three limit rods rotate, and the end of the metal pipe away from the three-jaw chuck is clamped and limited, thereby avoiding the situation that the end of the metal pipe away from the three-jaw chuck is usually against the baffle plate and is not limited. Therefore, the unrestricted end of the metal pipe is easy to move downward under the action of gravity during the cutting process, resulting in an uneven cutting surface.

[0007] Preferably, a roller is rotatably connected to the limiting rod.

[0008] The effect achieved by the above components is that when the limiting rod limits the metal pipe, the rotation of the metal pipe is not affected under the action of the roller, making the cutting process more stable.

[0009] Preferably, a connecting block is fixedly connected to the rotating ring, a rectangular block is rotatably connected to the fixed ring, a screw is rotatably connected to the rectangular block, and the screw is threadedly connected to the connecting block.

[0010] The effect achieved by the above components is: rotating the screw rod can drive the connecting block to move, thereby driving the rotating ring to rotate, and the screw rod limits the rotating ring to make the clamping more stable.

[0011] Preferably, a third motor is fixedly connected to the rectangular block, and an output shaft of the third motor is fixedly connected to the screw rod.

[0012] The effects achieved by the above components are: starting the third motor, and the output shaft of the third motor drives the screw to rotate, making the operation more convenient.

[0013] Preferably, an adjustment structure is provided on the cutting table, and the adjustment structure is mainly composed of an adjustment groove, and the adjustment groove is slidably connected to the limit plate.

[0014] The effect achieved by the above components is that the staff can slide the limit plate in the adjustment groove to adjust its position, so as to facilitate cutting of metal pipes of different lengths.

[0015] Preferably, a plurality of circular grooves are provided on the cutting table, and a round rod is slidably inserted on the limiting plate.

[0016] The effect achieved by the above components is that the round rod is clamped into the corresponding round groove, so that the limit plate can be limited, making the position of the limit plate more stable.

[0017] Preferably, a spring is sleeved on the round rod, one end of the spring is fixedly connected to the limit plate, and the other end of the spring is fixedly connected to the round rod.

[0018] The effect achieved by the above components is that when the round rod is inserted into the round groove, the spring is in a stretched state, so the rebound elastic force of the spring acts on the round rod, which can further improve the limiting effect.

[0019] Preferably, the cutting table is provided with scale lines, and the limiting plate is fixedly connected with a pointer.

[0020] The effect achieved by the above components is that the pointer and scale lines can facilitate the staff to accurately observe the position of the limit plate, making the cutting more accurate.

[0021] In the second aspect, the present invention provides a processing method of the cutting machine for processing metal raw materials as described above, wherein one end of the metal pipe is fixed on the three-jaw chuck, and the second motor is started. The output shaft of the second motor drives the threaded rod to rotate, so that the mounting plate can drive the metal pipe forward. When one end of the metal steel pipe is against the limit plate, the first motor is started. The output shaft of the first motor drives the three-jaw chuck to rotate, and then drives the metal steel pipe to rotate. The cutting gun is opened to cut the metal pipe. When the metal pipe is against the limit plate, the metal pipe will be stuck in the rotating ring. Then the rotating ring is rotated to drive the three return blocks to move, so that the three limit rods rotate, and the end of the metal pipe away from the three-jaw chuck is clamped and limited, thereby avoiding the problem that the end of the metal pipe away from the three-jaw chuck is usually against the baffle plate and is not limited. The limit rod is in the position of the metal pipe, so the unrestricted end of the metal pipe is easy to move downward under the action of gravity during the cutting process, resulting in an uneven cutting surface. When the limit rod limits the metal pipe, the rotation of the metal pipe can be not affected under the action of the roller, making the cutting process more stable. Rotating the screw can drive the connecting block to move, and then drive the rotating ring to rotate. The screw limits the rotating ring, making the clamping more stable. Starting the third motor, the output shaft of the third motor drives the screw to rotate, making the operation more convenient. The staff can slide the limit plate in the adjustment groove to adjust its position, which is convenient for cutting metal pipes of different lengths. The round rod is stuck into the corresponding round groove, and the limit plate can be limited, making the position of the limit plate more stable. When the round rod is stuck in the round groove, the spring is in a stretched state, so the rebound elastic force of the spring acts on the round rod.

[0022] Compared with the prior art, the advantages and positive effects of the present invention are that, in the present invention, by setting a limiting structure, when the metal pipe is against the limiting plate, the metal pipe will be stuck in the rotating ring, and then the rotating ring is rotated to drive the three return blocks to move, so that the three limiting rods are rotated, and the end of the metal pipe away from the three-jaw chuck is clamped and limited. When the limiting rod limits the metal pipe, the rotation of the metal pipe is not affected under the action of the roller, so that the cutting process is more stable, and the rotating screw can be driven to move the connecting block, and then drive the rotating ring to rotate. The screw limits the rotating ring, making the clamping more stable, and the third motor is started. The output shaft of the third motor drives the screw to rotate, making the operation more convenient, thereby avoiding the situation that the end of the metal pipe away from the three-jaw chuck is usually against the baffle plate and is not limited. Therefore, the unlimited end of the metal pipe is easy to move downward under the action of gravity during the cutting process, resulting in an uneven cutting surface.

One end of the metal pipe is fixed to the three-jaw chuck 4, and the second motor 7 is started. The output shaft of the second motor 7 drives the threaded rod 6 to rotate, so that the mounting plate 3 drives the metal pipe forward, and when one end of the metal steel pipe abuts against the limit plate 12, the first motor 5 is started, and the output shaft of the first motor 5 drives the three-jaw chuck 4 to rotate, which can then drive the metal steel pipe to rotate, and the cutting gun 11 is opened to cut the metal pipe.

Therefore, the unlimited end of the metal pipe is prone to move downward under the action of gravity during the cutting process, resulting in an uneven cutting surface. The limiting rod 84 is rotatably connected to a roller 85. When the limiting rod 84 limits the metal pipe, the rotation of the metal pipe is not affected under the action of the roller 85, making the cutting process more stable.

A spring 94 is provided, one end of the spring 94 is fixedly connected to the limit plate 12, and the other end of the spring 94 is fixedly connected to the round rod 93. When the round rod 93 is inserted into the circular groove 92, the spring 94 is in a stretched state, so the rebound elastic force of the spring 94 acts on the round rod 93, which can further improve the limiting effect. A scale line 96 is provided on the cutting table 1, and a pointer 95 is fixedly connected to the limit plate 12. The pointer 95 and the scale line 96 can facilitate the staff to accurately observe the position of the limit plate 12, so that the cutting is more accurate.

When one end of the metal steel pipe is against the limit plate 12, start the first motor 5, and the output shaft of the first motor 5 drives the three-jaw chuck 4 to rotate, which can then drive the metal steel pipe to rotate, open the cutting gun 11, and cut the metal pipe. When the metal pipe is against the limit plate 12, the metal pipe will be stuck in the rotating ring 82, and then the rotating ring 82 is rotated to drive the three return blocks 83 to move, so that the three limit rods 84 rotate, and the end of the metal pipe away from the three-jaw chuck 4 is clamped and limited, thereby avoiding the situation that the end of the metal pipe away from the three-jaw chuck 4 is usually against the baffle plate and is not limited. Therefore, the unrestricted end of the metal pipe is easy to move downward under the action of gravity during the cutting process, resulting in an uneven cutting surface. When 84 limits the metal pipe, under the action of roller 85, the metal pipe can be rotated without being affected, making the cutting process more stable. Rotating screw 89 can drive connecting block 86 to move, thereby driving rotating ring 82 to rotate. Screw 89 limits rotating ring 82, making the clamping more stable. Starting the third motor 88, the output shaft of the third motor 88 drives screw 89 to rotate, making the operation more convenient. The staff can slide the limit plate 12 in the adjustment groove 91 to adjust its position, which is convenient for cutting metal pipes of different lengths. The round rod 93 is inserted into the corresponding round groove 92, and the limit plate 12 can be limited, so that the position of the limit plate 12 is more stable. When the round rod 93 is inserted into the round groove 92, the spring 94 is in a stretched state, so the rebound elastic force of the spring 94 acts on the round rod 93, which can further improve the limiting effect. The pointer 95 and the scale line 96 can facilitate the staff to accurately observe the position of the limit plate 12, so that the cutting is more accurate.
