Description

Technical Field

[0001] The invention relates to the technical field of laser cutting, in particular to a right-angle elbow laser cutting machine. Background Art

[0002] According to the angle, the three most commonly used elbows are 45°, 90° and 180°. In addition, according to the needs of the project, there are also other abnormal angles such as 60°. According to the production process, it can be divided into welded elbows, stamped elbows, pushed elbows, cast elbows, etc. The materials of elbows include cast iron, stainless steel, alloy steel, forgeable cast iron, carbon steel, non-ferrous metals and plastics.

[0003] For metal right-angle elbows, a large number of elbows with special angles (such as 65°, 79°, 70°, 87°, etc.) are used in actual applications, and the elbows purchased are often 90° elbows. This requires the construction site to process the 90-degree elbows into elbows with corresponding special angles. The existing method for processing 90-degree elbows is manual cutting by manual marking. The cutting speed is slow and the cutting quality cannot be guaranteed. Many of them have to be repaired twice, and the quality of the cuts is also very poor.

[0004] In order to improve the cutting quality and cutting effect, a laser cutting machine is used to cut the right-angle elbow, such as an efficient laser cutting machine described in application No. 202310705104.1, which requires cumbersome manual interference in the right-angle elbow cutting process, and the right-angle elbow cutting efficiency is low, and the positioning method for the right-angle elbow is relatively cumbersome;

[0005] Another example is the fixing tool for elbow processing described in application number 202220767306.X, which positions one end of the right-angle elbow by setting a pipe mouth tightening mechanism, thereby fixing the right-angle elbow. This type of fixing method is prone to deformation of the right-angle elbow during end positioning due to the change in the curvature of the inner surface of the right-angle elbow, and is prone to vibration during laser cutting, resulting in a rough cutting surface and poor cutting quality.

[0006] Based on the search of the above information, it can be seen that the existing right-angle elbow has the defect of inconvenient fixation during laser cutting, which is not conducive to the efficient development of laser cutting and cannot guarantee the cutting quality of the right-angle elbow. For this reason, a right-angle elbow laser cutting machine is specially proposed to achieve convenient fixation of the right-angle elbow. While reducing manual interference, it can realize efficient and automatic laser cutting of the set angle, and at the same time can ensure the laser cutting quality of the right-angle elbow.

At the same time, with the settings of the radius adjusting part and the displacement adjusting part, it provides support for the coincidence adjustment of the axis of the servo motor and the axis of the center of one end of the right-angle elbow, and further provides accurate guarantee for the cutting of different bending angles of the right-angle elbow.

A cross plate 4016 is fixedly installed at the bottom of the slider 4012, and one side of the cross plate 4016 is fixedly connected to one side of the vertical plate 4010.

[0061] As a preferred solution, in order to prevent the vertical plate 4010 from being stuck due to unilateral force, a balance plate 4018 is fixedly installed at the bottom of the groove plate 407. A second guide rod 4019 is fixedly installed on one side of the balance plate 4018.

[0066] The advantages of the second embodiment compared with the first embodiment are as follows: The electric cylinder 603, the Y-axis telescopic rod 6051 and the Z-axis telescopic rod 6053 are introduced to form a three-coordinate high-precision moving platform, and the radius adjusting member 609 is combined to ensure the effective contact between the laser cutting member 2 and the outer surface of the right-angle elbow to be cut with different diameters, so as to facilitate laser cutting.

[0067] A method for using a right-angle elbow laser cutting machine specifically includes the following steps:

[0068] S1. Place the right-angle elbow on the support plate 4015, start the electric telescopic rod 402, the electric telescopic rod 402 extends, pushes the push plate 4017 to drive the fork plate 401 to move, the fork plate 401 drives the vertical plate 403 to make the two first positioning rollers 405 push the right-angle elbow to move. After the two ends of the right-angle elbow are respectively in contact with one side of the positioning plate 303 and one side of the driving plate 302, the end limit of the right-angle elbow is completed;

[0069] S2. As the electric telescopic rod 402 continues to extend, the first positioning roller 405 moves along the outer arc surface of the right-angle elbow, causing the linkage plate 404 to tilt and swing. At this time, the two linkage plates 404 are in an open state. During this process, the two linkage plates 404 drive the fixed shaft 406 to squeeze the groove plate 407. The groove plate 407 pushes the first guide rod 408 to move the vertical plate 4010. The vertical plate 4010 drives the horizontal plate 4016 to move. The horizontal plate 4016 drives the slider 4012 to slide inside the fork plate 401. During this process, the slider 4012 drives the L-shaped frame 4013 to bring the second positioning roller 4014 closer to the inner arc surface of the right-angle elbow until the second positioning roller 4014 contacts the inner arc surface of the right-angle elbow. At this time, the two first positioning rollers 405 and the second positioning roller 4014 complete the positioning of the right-angle elbow, and the electric telescopic rod 402 is turned off;

[0070] S3. Control the electric cylinder 603 to extend. The electric cylinder 603 pushes the push frame 604 closer to the right-angle elbow. The push frame 604 drives the cooperation plate 6041 to move, causing the cooperation plate 6041 to squeeze the rotating shaft 6043 downward. The rotating shaft 6043 drives the positioning plate 303 to move downward through the ear plate 6042 until the positioning plate 303 disengages from one end of the right-angle elbow;

[0071] During this process, the push frame 604 drives the fixed disk 607 to move through the displacement adjusting member 605, bringing the laser cutting member 2 closer to the edge of the working box 1. During this process, control the Y-axis telescopic rod 6051 to expand and contract. The Y-axis telescopic rod 6051 drives the Z-axis assembly table 6052 to move the assembly block 6054. The assembly block 6054 drives the connecting rod 606 to move the fixed disk 607. After the axis of the fixed disk 607 moves to the vertical plane where the center of one end of the right-angle elbow is located, control the Z-axis telescopic rod 6053 to expand and contract.
