Briefly describe the technology of laser cutting sheet metal

Laser cutting sheet metal technology is generally used in the processing of metal and non-metal materials, which can greatly reduce the processing time, reduce the processing cost and improve the quality of the workpiece. Shanghai sheet metal processing is the key technology for the needs of sheet metal technicians, and it is also an important process for the formation of sheet metal products.

It includes traditional cutting and blanking, blanking, bending and forming methods and process parameters, as well as various cold stamping die structures and process parameters, various equipment working principles and operating methods, as well as new stamping technology and new Process. The modern laser has become the "sword" of the "cutting iron and mud" that people dream of. Taking the Jinyun laser CO2 laser cutting sheet metal machine as an example, the whole system consists of control system, motion system, optical system, water cooling system, smoke exhausting and blowing maintenance system, etc. The most advanced numerical control form is used to complete multi-axis linkage and laser. It is not subject to the influence of speed and energy cutting. It also supports DX, P, PL, T, CNC and other graphic formats and enhances the interface graphics processing capability. The imported servo motor and transmission guiding structure with superior performance are selected at high speed. Outstanding motion accuracy.

Shanghai sheet metal processing sheet metal processing is called sheet metal processing. For details, such as making chimneys, iron drums, oil tanks, ventilation pipes, elbows, rounds, funnels, etc., the first process is cutting, bending, bending, zigzag, welding, riveting, etc. There must be a lot of common sense.

Laser-cut sheet metal is accomplished using the high-power (how much work done by the object in a unit of time) density energy generated by laser agglomeration. Shanghai sheet metal processing sheet metal processing is called sheet metal processing. For example, the use of sheet metal to make chimneys, iron drums, fuel tank oil cans, ventilation ducts, elbow heads, round spaces, funnels, and the like.

The first process is shearing, bending, folding, zigzag forming, welding, riveting, etc. The demand must be a little common sense. Under the control of the computer, the laser is discharged by pulse, thereby outputting a controlled repeated high-frequency pulsed laser to form a certain frequency, which must be used in the range of electron, optical, electromechanical, medical, etc., and the pulsed laser beam is transmitted through the optical path. And reflected and gathered by the collecting lens group on the outer surface of the processed object to form a subtle, high-energy-density spot, which is located near the surface to be processed, and melts or vaporizes the processed material in an instant. Each high-energy laser pulse instantly sputters a small hole into the surface of the object.

Under the control of the computer, the laser processing head and the processed material are continuously moved relative to each other according to the pre-drawn pattern, so that the object is processed into a desired shape. When cutting, a coaxial airflow with the beam is ejected by the cutting head, and the melted or vaporized data is blown out from the cut bottom. (Note: If the blown gas and the cut material generate a thermal response, the response will be supplied to the cutting. Additional power required; airflow also cools the cut surface, maximizing the reduction of the heat affected zone and ensuring that the condenser mirror is not contaminated). Compared with traditional sheet metal processing methods, laser-cut sheet metal has high cutting quality (small cutting width, small heat-affected zone, cut-off light), high cutting speed, high flexibility (can be freely cut into arbitrary shapes), and extensive Information is the same as the adaptability.
