Description

Technical Field

[0001] The invention relates to the technical field of laser cutting machines, in particular to a steel pipe laser cutting machine with a synchronous feeding function. Background Art

[0002] Laser cutting machine is to focus the laser emitted from the laser into a high power density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach the melting point or boiling point. At the same time, the high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, the material is eventually cut, thereby achieving the purpose of cutting.

[0003] At present, the external optical path of the laser cutting machine mainly adopts the flying optical path system. The light beam emitted from the laser generator passes through the reflectors 1, 2, and 3 to the focusing lens on the cutting head, and forms a light spot on the surface of the material to be processed after focusing. Among them, the reflector lens 1 is fixed on the machine body and does not move; the reflector 2 on the beam moves in the x direction with the movement of the beam; and the reflector lens 3 on the z-axis moves in the y direction with the movement of the z-axis. It is not difficult to see from the figure that during the cutting process, as the beam moves in the x direction and the z-axis part moves in the y direction, the length of the optical path changes all the time.

[0004] At present, when stainless steel tube laser cutting machines on the market are in use, they adopt chain-type transmission to feed materials, and realize single stainless steel tube feeding by controlling the distance of chain transmission. However, when feeding in this way, due to the lack of limiting components around the chain transmission, multiple stainless steel tubes may be transmitted at one time. As a result, the existing stainless steel tube laser cutting machines cannot perform the functions of precise pushing and synchronous feeding when in use. Therefore, a device is needed to improve the above-mentioned problem. Summary of the invention

In addition, the clamp in the auxiliary propulsion system 6 can be rotated on the hydraulic cylinder, so as to facilitate the pipe to change angles for cutting.

[0027] The working principle of Example 1 is as follows: when in use, first put the stainless steel tube into the receiving cavity 29 and onto the loading plate 31, then start the driving motor 10 to drive the circular plate 7 to rotate, and when the circular plate 7 drives the ring gear 8 to rotate to engage with the first gear 13, the ring gear 8 can drive the first gear 13 to rotate, and when the first gear 13 rotates, it can drive the second winding wheel 36 to rotate, so that the pushing plate 35 can be pulled into the receiving cavity 29 by the second connecting rope 37, so that the stainless steel tube at the bottom of the receiving cavity 29 can be pushed out from the receiving cavity 29, and then, when the pushing plate 35 is pulled to the extreme position, the pushing plate 35 can completely push the stainless steel tube out of the receiving cavity 29, and the stainless steel tube can be extended along the substrate. The top surface of 38 moves until the stainless steel pipe falls from the top of the extended base plate 38. A hydraulic cylinder is installed inside the lifting system 5, and a lifting frame is installed on the hydraulic cylinder, so that when the stainless steel pipe moves and falls from the extended base plate 38, it can enter the lifting frame. Subsequently, the hydraulic cylinder inside the lifting system 5 is turned on to drive the lifting frame and the stainless steel pipe to move upward until the stainless steel pipe can be aligned with the clamp in the auxiliary propulsion system 6. The hydraulic cylinder inside the auxiliary propulsion system 6 is then started, so that the clamp inside the auxiliary propulsion system 6 can move to contact with the stainless steel pipe, and then the clamp is opened. At the same time, the hydraulic cylinder inside the auxiliary propulsion system 6 can be continuously started, so as to squeeze the stainless steel pipe into the clamp inside the laser cutting system 4, and the stainless steel pipe can be cut by the laser. A feed wheel is installed inside the optical cutting system 4, and the feed wheel is adapted to the clamping claw, so that when the clamping claw clamps the stainless steel pipe, the feed wheel can contact the surface of the stainless steel pipe at the same time. Then, when the feed wheel is started, the stainless steel pipe can be driven into the laser cutting system 4, so that the laser cutting gun head can cut the stainless steel pipe and complete the feeding and cutting of the stainless steel pipe. Then, when the driving motor 10 is started again, the gear ring 8 can be driven to pass through the first gear 13, so that the first gear 13 can lose the meshing force. At this time, the elasticity of the second spring 33 will drive the push plate 35 to reset to the front end, so that the rear end of the push plate 35 can be moved out of the through hole at the bottom end of the receiving cavity 29, so that the stainless steel pipe located in the upper layer of the receiving cavity 29 will fall down to the receiving cavity 29. The inner bottom end of the cavity 29, then, when the circular plate 7 rotates one circle, it can drive the four gear rings 8 to pass through the first gear 13 in sequence, so that the four stainless steel pipes can be fed intermittently, and when the circular plate 7 rotates one circle, it can drive the convex plate 12 to contact the alignment plate 15, so that the alignment plate 15 can be squeezed to move toward the front end, and when the alignment plate 15 moves toward the front end, it can drive the rack 16 to pass through the second gear 18, so that the second gear 18 can drive the first winding wheel 19 to rotate, and when the first winding wheel 19 rotates, the top end of the loading plate 31 can be pulled by the first connecting rope 32 to rotate upward, and the loading plate 31 is rotated and hinged at the top front end of the receiving cavity 29, so that the loading plate 31 can receive the top front end of the cavity 29 as a base point and rotate upward,Therefore, the stainless steel pipe can slide along the surface of the loading plate 31 to the inside of the receiving cavity 29 to complete the loading of the stainless steel pipe. Subsequently, when the convex plate 12 passes through the alignment plate 15, the elasticity of the first spring 20 drives the alignment plate 15 to reset, and the guide rod 17 is slidably inserted into the inside of the extended bottom plate 14, so that the alignment plate 15 can be supported to move in a straight line. Moreover, when the alignment plate 15 is reset, it can also drive the rack 16 to pass through the second gear 18, so that the first winding wheel 19 can release the first connecting rope 32, and the loading plate 31 can rotate downward. When the loading plate 31 rotates downward, the connecting sleeve rod 28 and the second piston rod 27 can be driven to move downward. When the second piston rod 27 enters the interior of the L-shaped gas cylinder 25, the first piston rod 26 can be squeezed to drive the special-shaped connecting rod 24 and the push plate 23 to move. The push plate 23 is aligned with the gap inside the receiving cavity 29, so that when the push plate 23 moves into the receiving cavity 29, the stainless steel pipe inside the receiving cavity 29 can be pushed to move to the inner center of the receiving cavity 29, so that the stainless steel pipe can be accurately moved to the lifting frame. In addition, when the loading plate 31 is upward, When lifting, the second piston rod 27 and the connecting sleeve rod 28 can be pulled upward, so that the first piston rod 26 can enter the interior of the L-shaped air cylinder 25, so that the push plate 23 can be away from the receiving cavity 29, so that the stainless steel pipe can slide quickly into the interior of the receiving cavity 29, and the stainless steel pipe can be added to the interior of the receiving cavity 29. When the device is in use, the four gear rings 8 on the circular plate 7 are driven by the driving motor 10 to pass through the first gear 13 in sequence, so that the stainless steel pipe can be fed four times, and when the stainless steel pipe is fed four times, During operation, the convex plate 12 can be driven to contact the alignment plate 15, so that the rack 16 can pass through the second gear 18, drive the first connecting rope 32 to pull the loading plate 31 upward, so that the stainless steel pipe placed on the loading plate 31 can slide into the inside of the receiving cavity 29, and when the loading plate 31 is reset, the push plate 23 can enter the two ends of the receiving cavity 29, so that the stainless steel pipe stacked inside the receiving cavity 29 can be pushed toward the center of the receiving cavity 29, so that the push plate 35 can accurately push the stainless steel pipe onto the lifting frame to complete the work. Embodiment 2

[0028] On the basis of Example 1, Fig.10 As shown, the laser cutting system 4 also includes a collecting cavity 39 and a key 40. The key 40 is slidably inserted into the inner sides of the laser cutting system 4. The collecting cavity 39 is fixedly installed between the two keys 40. Slots are provided on both sides of the inner side of the laser cutting system 4, and the collecting cavity 39 is in contact with the left side of the inner side of the laser cutting system 4.

[0029] When implementing this embodiment, the collecting chamber 39 is located at the inner bottom end of the laser cutting system 4, so that the stainless steel tubes that are cut and dropped can be received, which is convenient for collectively taking the stainless steel tubes. Later, when the stainless steel tubes need to be taken out, the collecting chamber 39 can be pulled outward to take out the stainless steel tubes. Subsequently, after the stainless steel tubes inside the collecting chamber 39 are discharged, the collecting chamber 39 is moved toward the interior of the laser cutting system 4. A card slot is opened at the inner bottom end of the laser cutting system 4, and the card key 40 is located in the card slot and slides, so that the collecting chamber 39 can be supported to enter the interior of the laser cutting system 4 in a straight line, thereby improving the docking accuracy between the collecting chamber 39 and the laser cutting system 4.
