Description

Technical Field

[0001] The present invention relates to the technical field of laser pipe cutting machines, and specifically to a laser pipe cutting machine for cutting large-diameter pipes. Background Art

[0002] Laser pipe cutting machines have the advantages of fast cutting speed, high cross-section finish, and high cutting accuracy compared to traditional flame cutting and plasma cutting machines, and have been widely used in various industries in recent years. Currently, for the processing of large-diameter pipes, the feeding method generally uses a suspension device for lifting, which requires manual cooperation, is prone to collisions, and has a high risk of feeding. In addition, the clamping range of the clamping device of the current laser pipe cutting machine is insufficient to meet the clamping requirements of various pipe diameters. For the current laser pipe cutting machines, general large-diameter clamping devices have a relatively large inner diameter, are large and bulky, have a high equipment cost, and because the pipe diameter is large, manual intervention is often required during clamping and feeding to control the position, increasing the labor intensity and operation risk of the operator. Coupled with the possibility of human operation errors, the cutting accuracy and stability cannot be fully guaranteed. Summary of the Invention

At the top of the first hydraulic telescopic rod 45, there is a horizontal rotating shaft, and at the top of one side of the rotating shaft, there is a laser cutting head 46. The laser cutting head 46 can rotate through the rotating shaft. Combining the rotation of the rotating seat and the movement of the second slider 43 on the cross beam 42, the pipe can be cut at multiple angles and in multiple directions. A linear guide rail corresponding to the second slider 43 is provided on the cross beam 42 for the slider to move along the cross beam 42. By means of the linear guide rail and the corresponding power system, the position of the second slider 43 can be effectively adjusted to ensure the accuracy of the processing position and the processing accuracy.

[0028] On one side of both ends of the body 1, side frames 5 are provided. On the horizontal foundation 2 between the side frames 5, two parallel guide rail grooves 6 are provided. In the guide rail grooves 6, two corresponding guide rail frames 61 are provided. The top of the guide rail frame 61 is a V-shaped rail. On the outside of the V-shaped rail of the guide rail frame 61, tooth grooves corresponding to the rotating gears 77 are provided. Above both ends of the guide rail frame 61, load-carrying transport vehicles 7 are provided.

At the bottom of the moving blocks 76, rotating motors corresponding to the rotating gears 77 are provided. When the motors in the motor grooves rotate, the threaded rods rotate, causing the moving blocks 76 to move to positions close to the guide rail frames 61, so that the rotating gears mesh with the tooth grooves. When the rotating motors rotate, the rotating gears rotate, and in cooperation with the tooth grooves, the load-carrying transport vehicles move on the V-shaped rails of the guide rail frames 61. In cooperation with the first sliders 54, the laser cutting device 4 is moved to accurately process the pipes. Above the load-carrying transport vehicle 7, a hydraulic telescopic column 8 is provided. At the top of the hydraulic telescopic column 8, a fixed shaft seat 81 is provided. In the fixed shaft seat 81, a rotating motor is provided, and at the top of the rotating shaft of the rotating motor in the fixed shaft seat 81, a double-layer clamping device 82 is provided. On the other side of the horizontal foundation 2, an adjustable material rack 3 corresponding to the body 1 is provided.

[0029] On both sides of the adjustable material rack 3, a number of legs are provided. The legs on one side of the adjustable material rack 3 are all set as hydraulic telescopic rods. Through the hydraulic telescopic rods, the inclination angle of the adjustable material rack 3 can be effectively controlled. On the adjustable material rack 3, a number of rotating shafts are horizontally arranged. On the side surfaces of the adjustable material rack 3 at both ends of the rotating shafts, rotating motors corresponding to the rotating shafts are provided. On the rotating shafts, a number of semi-circular pipe fixing blocks are provided. Combining the lifting of the hydraulic telescopic rods, the pipes are ensured to slide step by step along the inclination angle, ensuring the stability of feeding. For pipes with different diameters, different inclination angles can be used to ensure the stability of feeding on the material rack.

[0030] The body 1 includes an inner cross frame 51 connecting the two side frames 5. Outside the inner cross frame 51, an outer cross frame 52 corresponding to the inner cross frame 51 is arranged in parallel.

On the first sliders 54, a laser cutting device 4 is provided. By setting a conventional guide rail power system, the processing position of the laser cutting device 4 can be changed, improving the flexibility of processing.

[0031] The double-layer clamping device 82 includes a three-jaw chuck 83 at the top end and a fixed cylinder 84 at the rear end. An annular hydraulic oil chamber 85 is provided inside the fixed cylinder 84. The hydraulic oil chamber 85 is connected to a corresponding hydraulic pump. Through the hydraulic pump, the hydraulic telescopic rod on it can be effectively telescoped. Four hydraulic telescopic rods are evenly arranged in a circumferential shape on the fixed cylinder 84 and are connected to the hydraulic oil chamber 85. Clamping blocks 86 are provided at the tops of these hydraulic rods. The clamping blocks 86 are multi-layer stepped structures that rise inward, and the inner and outer sides of each step are wedge-shaped. They can be used to clamp the inner diameter of large-diameter pipes for corresponding processing. The three-jaw chuck 83 is used to clamp pipe materials with smaller diameters. When necessary, the upper structure of its jaws can be modified into the structure of the clamping block 86 to further increase the clamping diameter range and improve the clamping ability.

[0032] Correspondingly, two rows of parallel hydraulic telescopic rods are provided at the bottom of the guide rail groove 6. A guide rail frame 61 is provided at the top of the hydraulic telescopic rods in the guide rail groove 6. The hydraulic telescopic rods here are used for the lifting control of the guide rail frame 61. A dust-proof frame 62 is arranged in parallel at the bottom of the V-shaped rail of the guide rail frame 61. When the V-shaped rail of the guide rail frame 61 coincides with the track groove 63, the dust-proof frame 62 rises to the surface of the horizontal foundation to prevent dust from entering the track. During processing, the dust is removed manually or by setting a dust removal device, and then the guide rail frame 61 is retracted. Tooth grooves corresponding to the rotating gear 77 are provided on the outer side of the V-shaped frame of the guide rail frame 61, so that the load-carrying transport vehicle 7 can move effectively on the V-shaped rail.

[0033] Above the inner side surface of the inner horizontal frame 51, several support frames 55 are provided. The support frames 55 include two pairs of symmetrically arranged fixed ear seats 56. A rotating shaft 57 is provided inside the fixed ear seats 56. A rotating motor is provided on the outer side of one side of the fixed ear seats 56. A cantilever 58 is provided on the rotating shaft 57. Two parallel rollers 59 are provided at the top of the cantilever 58. Several disc support blocks 60 are provided on the rollers 59. The horizontal projection of the perpendicular bisector of the circular connection of the disc support blocks 60 coincides with the central symmetry line of the guide rail frame 61. The diameter of the disc support blocks 60 is set according to actual needs. When necessary, motors can be provided at both ends of the rollers 59 to control the rotation of the rollers 59 to assist the rotation of the pipe material.

[0034] A limit block 50 is provided at the tail end of the cantilever 58. The upper side of the outer side of the limit block 50 is provided with a rounded corner, and the lower side of the outer side of the limit block 50 is a right angle. The right-angle structure restricts the further downward rotation of the cantilever 58, and the rounded corner setting facilitates the upward rotation and retraction of the cantilever 58.

[0035] The load-carrying transport vehicle 7 is an omnidirectional intelligent vehicle with Mecanum wheels and is a heavy-duty Mecanum wheel vehicle. It can complete omnidirectional movement through a corresponding intelligent system by setting a corresponding detection device.

[0036] Working principle: First, load the pipe material onto the adjustable rack. Two load-carrying transport vehicles are moved to both ends of the pipe material through the operation of the corresponding intelligent system. The load-carrying transport vehicle is a heavy-duty Mecanum wheel trolley, which can be identified, confirmed, and controlled through the setting of corresponding detection devices and the corresponding intelligent system. The height is adjusted by the hydraulic telescopic column. For pipes with a smaller diameter, they can be clamped by a three-jaw chuck. For pipes with a larger diameter, the clamping block is pushed by the hydraulic telescopic rod to clamp the inner diameter of the pipe. The hydraulic telescopic column is lifted, and the load-carrying transport vehicle is controlled by the intelligent system to transport the pipe. At this time, the support frame is lowered by the motor. The bottom track groove of the load-carrying transport vehicle is made to fit with the track through the setting of the corresponding identification device and the intelligent control system. The hydraulic telescopic column is lowered and adjusted to make the support frame provide support. Different numbers of support frames can be selected according to the length of the pipe. Under the action of the hydraulic telescopic rod, the guide rail frame makes the V-shaped rail fit with the track groove. At this time, the rotation of the motor in the motor groove drives the threaded rod to drive the moving block to move, so that the rotating gear meshes with the pool groove on the outside of the V-shaped rail. Through the rotation of the rotating motor on the moving block, the load-carrying transport vehicle can move back and forth along the track. When the guide rail frame rises, the dust-proof frame is just parallel to the horizontal foundation to prevent dust from flowing into the guide rail during processing. Each time processing is carried out, the accumulated dust is removed manually or by setting a dust removal device. After processing is completed, the product is taken off, the guide rail frame is lowered, the load-carrying transport vehicle resumes moving, and it moves out for the next material taking. The support frame can be retracted for repetitive operation processing. In this invention application, the corresponding moving operations are all provided with corresponding power systems, identification devices, and intelligent operating systems. Information is collected through conventional identification devices, and the intelligent system controls the power system to operate. For those skilled in the art, the setting of the identification device and the power system are both set according to actual needs and can be adjusted adaptively, not limited to the implementation mode of this application.

Therefore, in any aspect, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention.
