Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting, and in particular to intelligently manufactured tube laser cutting equipment. Background Art

[0002] Intelligent manufacturing pipe laser cutting equipment is a device that uses a high-energy-density laser beam to accurately cut pipes. It can also process complex shapes on the surface of pipes. It is widely used in furniture manufacturing, medical equipment manufacturing and other fields.

[0003] During the laser cutting process, a protective gas is required to blow away the molten material. When the pipe is cut, the molten material will splash onto the inner surface of the pipe, reducing the processing quality. Especially when the pipe is cut, the molten material will splash into the cut gap and the pipes at both ends of the welding gap, resulting in the pipe being unable to be cut. In the prior art, workers insert another pipe into the raw pipe to prevent splashing. This later inserted pipe is called a splash-proof pipe. Since the molten material splashes onto the outer surface of the splash-proof pipe, the processing quality of the processed pipe is improved. Usually, the remaining tailings are used as splash-proof pipes.

[0004] However, each time this method cuts the raw pipe to generate a finished pipe, the worker needs to take out the splash-proof tube and the finished pipe, and then reinsert the splash-proof tube into the raw pipe. Since the temperature of the splash-proof tube is relatively high, it is easy to burn the workers, posing a safety hazard. Since the laser beam energy is relatively high, it will gradually damage the splash-proof tube, and the workers need to regularly replace the splash-proof tube. Therefore, the existing pipe laser cutting technology has the defect of low automation level. Summary of the invention

DETAILED DESCRIPTION

[0039] 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.

[0040] The present invention provides a technical solution: an intelligently manufactured tube laser cutting device, such as Figure 1 , 2As shown, it includes a bed 101 and a splash-proof pipe 201, wherein the bed 101 is fixed on the ground, a rear support 102 is slidably arranged on the bed 101, and the rear support 102 realizes the functions of clamping, moving and rotating the pipe by the existing technology, a front support 103 is fixed at the front end of the bed 101, and the front support 103 realizes the function of supporting the pipe by the existing technology, and the raw material pipe 104 is supported on the rear support 102 and the front support 103, and a CNC workbench 105 is installed at the front end of the bed 101, and the CNC workbench 105 is a driving A common part for the movement of a driven member. The CNC workbench 105 in this embodiment can drive the laser cutting head 106 to make vertical and horizontal movements. The laser cutting head 106 is installed on the CNC workbench 105. An automatic loader 107 is fixed on the ground on one side of the bed 101. The automatic loader 107 is a common equipment used in conjunction with laser pipe cutting machines, pipe bending machines and other pipe processing equipment. The rear support 102, the front support 103, the CNC workbench 105, the laser cutting head 106 and the automatic loader 107 are electrically connected to the host computer.

[0041] The splash-proof tube 201 is arranged in the raw material pipe 104, and the splash-proof tube 201 is tightened by the inner support head 300, and the inner support head 300 is fixedly installed on the support pipe 202, and the support pipe 202 is clamped by the splash-proof support 203, and the splash-proof support 203 realizes the functions of clamping the pipe, moving the pipe, and rotating the pipe through the existing technology, and the splash-proof support 203 is slidably arranged on the side of the frame 204, and the frame 204 is arranged on the ground in front of the bed 101, and the side of the frame 204 is slidably arranged with a baffle support 400, and the rear end of the frame 204 is fixed with a finished product slope 205, and the splash-proof support 203 and the baffle support 400 are electrically connected to the upper computer, and the splash-proof tube 201 is connected to the upper computer through the upper computer. The inner support head 300 and the support tube 202 are fixed on the splash-proof support 203, and the splash-proof support 203 is slidably set on the frame 204. Each time the raw pipe 104 is cut to generate a finished pipe, the splash-proof support 203 can drive the splash-proof tube 201 away from the raw pipe 104, so that the finished pipe falls onto the finished product slope 205, avoiding the workers from manually taking out the splash-proof tube 201, thereby improving the safety and automation level of the pipe laser cutting. Through the cooperation of the support tube 202 and the rear support 102, the splash-proof tube 201 can gradually penetrate into the raw pipe 104 during the processing, so that the shorter splash-proof tube 201 can also adapt to the longer finished pipe.

[0042] Each time a raw material pipe 104 is cut to generate a finished pipe, the finished pipe will fall onto the splash-proof tube 201. Due to the effect of friction, when the splash-proof support 203 drives the splash-proof tube 201 away from the raw material pipe 104, the finished pipe will move with the splash-proof tube 201. The baffle support 400 can prevent the finished pipe from moving with the splash-proof tube 201, ensuring that the finished pipe falls on the finished product slope 205.

[0043] like Figure 1 As shown, a manipulator 500 and a tail material rack 600 are fixed on the ground on one side of the frame 204. The manipulator 500 can move the used anti-splash tube 201 on the inner support head 300 to the tail material rack 600, and install the tail material 108 on the tail material rack 600 on the inner support head 300 for use as a new anti-splash tube 201. The manipulator 500 and the inner support head 300 are electrically connected to the host computer. Through the cooperation of the manipulator 500 and the tail material rack 600, the new anti-splash tube 201 can be automatically replaced regularly, thereby improving the level of automation. In conjunction with the automatic loader 107, long-term automatic processing can be achieved.

[0044] like Figure 3 , 4 As shown, the inner support head 300 includes an inner support shell 301, a wedge block 302 and two inner support claws 303, each of the inner support claws 303 is slidably arranged in the inner support shell 301, the inner support shell 301 is detachably fixed on the support tube 202, one end of the inner support claw 303 is in contact with the splash-proof tube 201, and the other end is provided with an inclined surface, the inclined surface of the inner support claw 303 is in contact with the wedge block 302, and the wedge block 302 is slidably arranged in the inner support shell 301 Inside, one end of a rope 304 is fixed on the wedge block 302, and the other end of the rope 304 is driven by a tensioning motor 305, and the tensioning motor 305 is electrically connected to the host computer. One end of a tensioning rod 306 is fixed on the output shaft of the tensioning motor 305, and the other end of the tensioning rod 306 is fixed with the rope 304, and a tension spring 307 is fixed between the two inner support claws 303. After the rope 304 is relaxed, the tension spring 307 drives the two inner support claws 303 to move closer to each other.

[0045] The tensioning motor 305 drives the tensioning rod 306 to rotate, thereby tightening the rope 304, thereby driving the wedge block 302 to move. The movement of the wedge block 302 drives the two inner support claws 303 to move away from each other, thereby tightening the splash-proof tube 201. The tensioning motor 305 drives the tensioning rod 306 to rotate in the opposite direction, the rope 304 relaxes, and the tension spring 307 drives the two inner support claws 303 to move closer to each other, thereby loosening the splash-proof tube 201.

[0046] like Figure 5As shown, the baffle support 400 includes a baffle housing 401, a forward and reverse threaded screw 402 and two baffles 403, the baffle housing 401 is slidably set on the frame 204, a baffle gear is rotatably set on the baffle housing 401, the baffle gear is driven by a baffle motor 404, the baffle motor 404 is fixed on the baffle housing 401, the baffle motor 404 is electrically connected to the host computer, the baffle gear is meshed with a fixed rack 405, the fixed rack 405 is fixed on the frame 204, the forward and reverse threaded screw 402 is rotatably set in the baffle housing 401, the forward and reverse threaded screw 402 is coaxially fixed with a handle, and the forward and reverse threaded screw 402 is threadedly connected with The two baffle plates 403, one baffle plate 403 is connected to the forward and reverse screw 402 through a left-handed thread, and the other baffle plate is connected to the forward and reverse screw 402 through a right-handed thread. Each baffle plate 403 is slidably arranged in the baffle housing 401. The baffle motor 404 can drive the baffle gear to rotate, and then drive the baffle gear to roll on the fixed rack 405, thereby driving the baffle support 400 to move on the frame 204. Turning the handle can drive the forward and reverse screw 402 to rotate, and then drive the two baffle plates 403 to move, thereby adjusting the distance between the two baffle plates 403, so that the baffle support 400 can adapt to raw pipes 104 of different diameters.

[0047] like Figure 6 As shown, the tailing rack 600 includes a fixed rack 601, a movable rack 602 and a parallelogram mechanism 700. The fixed rack 601 is fixed on the ground on one side of the rack 204 in parallel with the rack 204. The fixed rack 601 is provided with a plurality of V-shaped grooves, which can accommodate tailings 108. A discharge slope 603 is fixed in front of the fixed rack 601. The V-shaped groove close to the discharge slope 603 is called a first V-shaped groove 604. The movable rack 602 is provided on the side of the fixed rack 601. There are multiple V-shaped grooves, the movable frame 602 is driven by a parallelogram mechanism 700, the parallelogram mechanism 700 is driven by a transmission mechanism 800, and the parallelogram mechanism 700 is arranged on the side of the fixed frame 601. After the manipulator 500 moves the splash-proof tube 201 on the inner support head 300 to the first V-shaped groove 604 of the fixed frame 601, the parallelogram mechanism 700 works once, so that the movable frame 602 moves to transport the splash-proof tube 201 to the unloading slope 603, and at the same time drives the tail material 108 to move forward one V-shaped groove.

[0048] When replacing the splash-proof tube 201, the manipulator 500 first moves the splash-proof tube 201 to the first V-shaped groove 604 of the fixed frame 601, and then the manipulator 500 gives way, and the parallelogram mechanism 700 works once, causing the movable frame 602 to move to transport the splash-proof tube 201 to the unloading slope 603, while driving the tail material 108 to move forward a V-shaped groove, and the manipulator 500 moves again to install the tail material 108 on the inner support head 300.

[0049] Through the cooperation of the fixed frame 601, the movable frame 602 and the unloading slope 603, the used splash-proof tube 201 can be conveniently discarded and the tailings 108 can be accurately moved. When replacing the splash-proof tube 201, the manipulator 500 can complete the work of removing the tailings 108 and removing the splash-proof tube 201 at the same position, which is convenient for positioning the manipulator 500 and controlling the manipulator 500.

The other end of the crank 901 is hinged to one end of the connecting rod 902, and the other end of the connecting rod 902 is hinged to the slider 903.
