What should be paid attention to in the layout of fiber laser cutting machine? Before using the laser cutting machine, we will import the created drawings into the program, and then use the typesetting software to arrange the graphics on a board, so that the laser cutting machine can batch process the products. Among them, although the typesetting process is very short, there is a lot of knowledge hidden in it. If the typesetting is not correct, it will have a great impact on the cutting effect of the entire board. So, here are the six major considerations in typesetting. 1. Corner melting When decelerating the corner of a thin steel plate, the laser will melt the corner due to overheating. A small radius is generated at the corner to maintain high-speed laser cutting, to avoid overheating and melting of the steel plate when cutting the corner, thereby obtaining good cutting quality, reducing cutting time, and improving productivity. 2. Co-edge cutting Co-edge two or more parts into a combination. Large-scale regular graphics should be co-edge as much as possible. Co-edge cutting can greatly shorten the cutting time and save raw materials. 3. Processing of residual materials After cutting the parts, the skeleton-shaped residual materials on the working table of the laser cutting equipment need to be removed as soon as possible to facilitate the subsequent cutting operations. For laser cutting equipment that does not have an automatic discharge device, the skeleton-shaped residual material can be cut into small pieces to facilitate quick removal. Therefore, the personal injury caused by the operator with heavy and sharp edges is avoided.
4. In general, the distance between parts is used to cut thick plates and hot plates. The distance between parts should be large, because the heat effect of the hot plate on the thick plates is greater. When the graphics are small, it is easy to burn the edges and affect the cutting quality. 5. The lead wire is set in the process of cutting the thicker board. In order to make the cut joint well and prevent the beginning and end burns, often lead a section of transition line at the beginning and end of the cutting, called the lead wire and the tail wire. It is useless for the workpiece itself, so it should be arranged outside the scope of the workpiece, and at the same time, pay attention not to set the lead wire at a sharp corner and other places that are not easy to dissipate heat. The connection between the lead wire and the slit is made with an arc transition as much as possible to make the machine move smoothly and avoid the burn caused by the corner stop. 6. Parts collision In order to maximize production efficiency, many laser cutting equipment are running continuously for 24h, and use unmanned automatic loading / unloading device, hitting the tilted parts after cutting, causing damage to the cutting head and production interruption , Bring greater losses. This requires attention when sorting: ① Select a suitable cutting path to bypass the cut parts to reduce collision. ②Select the best cutting route and reduce the cutting time. ③Automatically or manually combine multiple small parts with tiny connections. After cutting, the removed parts can easily disconnect the tiny connections. More info
