Research on Application Technology of Fiber Laser Fast Cutting Thin Plate
With the rapid development of sheet metal processing technology, fiber laser cutting machines, especially fiber laser cutting machines, have become the mainstream processing equipment in this field. The market demand is increasing exponentially, and the market share continues to increase. In the past few years, the fiber laser cutting machine was mainly based on low and medium power, and in recent years, it has gradually developed in the direction of high power. High-power fiber lasers have higher cutting capabilities (speeds). How to make higher-power fiber lasers as high as possible processing efficiency is subject to many factors: such as machine tool structure, light source quality, control system, application technology, etc. . This article mainly analyzes and studies the improvement of sheet processing efficiency from the aspect of application technology.
Analysis and research on the processing process of fiber laser cutting machine
The main processing process of fiber laser cutting machine is: drawing-programming-machine cutting processing.
Drawing
Drawing refers to drawing the parts to be processed into CAD drawings (or converting them into CAD drawings). This process is a secondary factor in improving the efficiency of machine tools. Not much to repeat.
Programming
Programming refers to the conversion of CAD drawings into program codes that the machine tool can recognize and process. The process is as follows: typesetting-checking error correction-compiling (tooling processing)-generating code .
Typesetting
Reasonable and scientific typesetting can increase the utilization rate of the plate, increase the utilization rate of the plate, increase the number of parts processed in a single time, reduce the total processing time required for batch products, and reduce the efficiency improve.
Check error correction
Check error correction can display or automatically modify the wrong graphics, including the same position repeated (multiple) line segment error correction, if there is no such process, the machine tool will Perform multiple cuts at the same position. Such cutting is abnormal processing, which not only reduces efficiency and wastes costs, but may also damage the machine tool.
Compilation
Compilation refers to the process of matching and processing the qualified and intact CAD drawings according to the production process requirements. Compilation has a great effect on fast and stable production: ①Reasonable processing path can improve processing efficiency; ②Reasonable micro-connection can improve the stability of machine tool processing, which is also helpful to improve processing efficiency; ③Reasonable common edge cutting can be used Reducing the cutting path can reduce the processing time and processing cost, and improve the utilization rate of the sheet; ④Reasonable puncture methods can also improve processing efficiency.
Generate code
Generate code means to convert the compiled processing graphics into code that can be recognized by the machine tool. The processing efficiency is a secondary factor, so I won't go into details.
The auxiliary work such as loading and unloading of the machine tool cutting workers is omitted, and the focus is on the analysis of the program cutting process: ①Protection of protective gas (cutting head lens anti-pollution); ②Plate pretreatment (reading processing data and defining origin ); ③Quickly locate (leapfrog) to the contour to be cut; ④Turn off the protective gas; ⑤Exhaust the puncture gas and perform the follow-up action; ⑥Emit the piercing stimulus light (after the follow-up action is completed) Turn off the puncture gas; ⑨ out the cutting gas; 10 launch the cutting laser (cutting contour); 11 the end of contour cutting (turn off the cutting laser, cutting gas, etc.); 12 out of protective gas; 13 fast positioning (leapfrog) to the next contour; 14 Cycle steps ④~13; 15 cutting processing ends; 16 turning off the shielding gas;
The processing process of the fiber laser cutting machine is analyzed and tested, and the processing process of the machine tool needs to be improved and optimized. The purpose and goal of improvement and optimization is to increase the processing efficiency of the machine tool as much as possible; to ensure that the machine tool can work safely and normally; not to increase the consumption of the machine tool's wearing parts. The optimized cutting process is as follows: ① Out of protective gas (to prevent contamination of the cutting head lens); ② Plate pretreatment (read processing data and define the origin, etc.); ③ Quickly locate (leapfrog) to the contour to be cut. Cancel the action of 'turn off the shielding gas
