Description

Technical Field

[0004] The invention relates to the technical field of metal tube processing, in particular to a turntable type automatic loading and unloading laser tube cutting machine. Background Art

[0005] At present, although there are various types of laser tube cutting machines in the market, they generally use a chuck to clamp the profile or tube and rotate and move it to cut. According to the number of chucks, it can be divided into two chucks, three chucks, four chucks and other types. This cutting method works better when cutting medium and small tubes, but when the weight of a single tube is heavy and the size is large, the required chuck size will also increase accordingly, making it difficult to rotate the tube, the rotation accuracy is difficult to guarantee, and the cost is high.

[0006] For the processing of long and heavy pipes, there are still the following problems: due to the long and heavy pipes, the pipes are prone to material stripping and emptying during the feeding process, and the feeding accuracy cannot be ensured1. In addition, in the process of traditional laser cutting of profiles or pipes, the method of using a chuck to fix and rotate the workpiece also has problems such as positioning error, high operation complexity, low production efficiency and safety hazards.

[0007] Although the existing automatic loading and unloading laser tube cutting machines have solved the problem of manual intervention to a certain extent, there are still many shortcomings. For example, some equipment is only suitable for profiles or tubes of specific shapes or sizes, and cannot flexibly respond to the needs of products of various specifications; for long and heavy materials, existing equipment may shake or shift during the feeding, cutting and discharging process, affecting the cutting quality and yield rate; although some automation functions have been realized, many links still rely on manual operation and fail to achieve full process automation; the complex mechanical structure leads to a large workload for later inspection and maintenance, which increases operating costs.

[0063] Working principles of each preferred technical solution

[0064] Chain type automatic feeding machine 6:

[0065] The chain is driven by a motor to move and transport the profiles or pipes to be processed to the supporting mechanism 12, thereby realizing automatic material supply.

[0066] Feeding clamping mechanism 8:

[0067] It is installed on the guide rail on the feeding frame 7 and moves along the guide rail through the slider. The clamping cylinder 13 drives the clamping plates 14 on both sides to move, and cooperates with the gear and the centering synchronous rack 49 to ensure that the profile or pipe can be firmly clamped. The detection device 15 is used to confirm the material position and ensure the accuracy of feeding.

[0068] Cutting mechanism 1:

[0069] It includes a sliding plate 17 that can be raised and lowered, a rotating body 18, and a moving unit 22 for the cutting head 38. The sliding plate 17 slides up and down along the slide rail on the machine base 16 to adjust the height of the rotating body 18; the rotating body 18 can make circular motions, and the cutting head 38 installed thereon can move in the X and Z directions to complete precise cutting tasks. The drag chain retracting device 20 ensures the orderly management and tension control of connecting wires such as cables. The pressing device 23 uses a cylinder to control the lifting of the pressing roller to ensure that the workpiece does not shake during cutting. The lifting device 19 uses a screw lift 59 and a dual-axis motor 58 to provide smooth lifting and lowering movements.

[0070] Cutting head 38 mobile unit 22:

[0071] The servo motor is used to drive the threaded screw so that the cutting head 38 can move accurately in the X direction and the Z direction to achieve multi-angle and multi-directional cutting operations. The cutting head 38 can be a laser cutting head 38 with mature application technology.

[0072] Material pulling clamping mechanism 3:

[0073] Similar to the design of the feeding clamping mechanism 8, it is particularly suitable for handling the delivery of cut parts, and the height can be adjusted by the lifting cylinder 25 to avoid obstacles. Its internal structure includes a blanking clamping plate 26, a clamping cylinder 260, a synchronous wheel and a centering synchronous rack 27 to ensure the consistency of the action of the blanking clamping plate 26.

[0074] Drivetrain:

[0075] The guide rails on the loading rack 7 and the unloading rack 2 are provided with a transmission rack 51, which meshes with the transmission gear 52 installed at the output end of the transmission motor 50 inside each moving component (such as the feeding clamping mechanism 8 and the pulling clamping mechanism 3) to achieve smooth movement.

[0076] Detailed workflow

[0077] Preparation stage:

[0078] The profiles or pipes are placed on the chain-type automatic feeder 6. After starting, the feeder is driven by a motor to rotate the chain, and the profiles or pipes are transported to the supporting mechanism 12 in sequence.

[0079] Centering and initial clamping:

[0080] The centering mechanism 9 centers the pipe or profile to prepare for subsequent operations. Then, the feeding clamping mechanism 8 moves forward, and when the detection device 15 senses the material, the clamping cylinder 13 is activated to close the clamping plates 14 on both sides and firmly grasp the profile or pipe.

[0081] Precise positioning and fixing:

[0082] The feeding clamping mechanism 8 continues to move forward to the position of the centering mechanism 9, and the centering mechanism 9 is lowered to avoid the feeding clamping mechanism 8. Before the material reaches the cutting mechanism 1, the feeding clamping positioning mechanism 10 and the unloading clamping positioning mechanism 4 work together to fix the profile or pipe and prepare for cutting.

[0083] Cutting operation:

[0084] When cutting starts, the rotating body 18 adjusts the angle as needed, and the cutting head 38 moves along the X and Z directions to perform the cutting action. During the entire cutting process, the pressing device 23 continuously presses the profile or pipe to ensure that it is stable and motionless. The pressing device 23 uses a cylinder to push the pressing roller up or down to press the profile or pipe.

[0085] Finished product pulling out and flipping out:

[0086] After cutting is completed, the material pulling and clamping mechanism 3 is activated to clamp and pull the cut part away from the cutting area. The material pulling and clamping mechanism 3 moves the finished product to the unloading position, and then the unloading flipping mechanism 5 is started, and the flipping plate 28 is flipped under the action of the flipping cylinder 30, and the finished product is stably placed on the storage rack 11.

[0087] Repeated cycle:

[0088] After completing a complete cutting and unloading, the machine returns to the initial state, ready to receive the next profile or tube to be processed and repeat the above process.

[0089] This turntable automatic loading and unloading laser tube cutting machine realizes efficient, accurate and safe cutting of profiles or tubes, significantly improving production efficiency and product quality. It is especially suitable for processing long and heavy profiles and tubes. The optimized design reduces the unstable factors in the traditional process and improves the cutting accuracy and stability.

[0090] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
