Description

[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 during design 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.

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.

[0005] 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.

9. The right-angle elbow laser cutting machine according to claim 8, characterized in that: The method for using the right-angle elbow laser cutting machine specifically includes the following steps: S1. Place the right-angle elbow on the support plate, start the electric telescopic rod, extend the electric telescopic rod, push the push plate to drive the fork plate to move, the fork plate drives the vertical plate to make the two first positioning rollers push the right-angle elbow to move, and after the two ends of the right-angle elbow are respectively in contact with one side of the positioning plate and one side of the driving plate, the end limit of the right-angle elbow is completed; S2. As the electric telescopic rod continues to extend, the first positioning roller moves along the outer arc surface of the right-angle elbow and causes the linkage plate to tilt and swing. At this time, the two linkage plates are in an open state. During the process, the two linkage plates drive the fixed shaft to squeeze the slot plate. The slot plate pushes the first guide rod to move the vertical plate, and the vertical plate drives the horizontal plate to move. The horizontal plate drives the slider to slide inside the fork plate. During the process, the slider drives the L-shaped frame to make the second positioning roller close to the inner arc surface of the right-angle elbow until the second positioning roller contacts the inner arc surface of the right-angle elbow. At this time, the two first positioning rollers and the second positioning rollers complete the positioning of the right-angle elbow, and the electric telescopic rod is closed; S3, control the electric cylinder to extend, the electric cylinder pushes the push frame close to the right-angle elbow, the push frame drives the collaborative plate to move, so that the collaborative plate presses the shaft downward, and the shaft drives the positioning plate to move downward through the ear plate until the positioning plate is separated from one end of the right-angle elbow; During the process, the push frame pushes the fixed plate to move through the displacement adjustment member, so that the laser cutting part is close to the edge of the working box. During the process, the Y-axis telescopic rod is controlled to extend and retract, and the Y-axis telescopic rod pushes the Z-axis assembly table to move the assembly block, and the assembly block drives the connecting rod to move the fixed plate. After the axis of the fixed plate moves to the vertical plane where the center of one end of the right-angle elbow is located, the Z-axis telescopic rod is controlled to extend and retract, and the Z-axis telescopic rod drives the assembly block to move the axis of the fixed plate to coincide with the axis where the center of one end of the right-angle elbow is located, and the adjustment is completed; S4. According to the angle of the right-angle elbow to be cut, the rotating motor is controlled to rotate, the rotating motor drives the turntable to rotate, the turntable drives the drive plate and the pin shaft to rotate, the pin shaft drives the electric telescopic rod to rotate, and the electric telescopic rod rotates the fork plate through the push plate. After the right-angle elbow positioned in S2 is rotated to the set angle, the adjusting motor is started, and the adjusting motor drives the lead screw to rotate, so that the moving table drives the laser cutting part to approach the outer circle to be cut of the right-angle elbow, and the servo motor and the laser cutting part are started. The servo motor drives the assembly frame to rotate one circle to complete the cutting of the set angle of the right-angle elbow, and the cut waste falls into the waste hopper.
