Typical applications are as follows: the metal mold. Metal forming mold is widely used in industry. Almost all of the contact surface of the sheet are easy to wear, especially in contact with the fillet parts of these areas through the flame or electromagnetic induction can be hardened. The laser hardening for the surface hardening of the accurate and rapid processing. The lowest heat input to minimize the degree of twisting. Can be hardened to 5m long, 25mm wide, 3m deep, the flexibility of laser hardening makes all kinds of mold are hardening. Laser hardening of the metal mold, a growing application of laser beam hardening plastic injection molds, the typical mold, such as section or the overall shape of the mold weighing 10 tons or more. green laser pointer has become the light spot of various parties or locations.
In the production process, the high injection pressure (~ 100bar) will lead to serious wear in the entrance and the sealing surface, especially when the wear medium in the plastic mold wear may cause parts to the burr, and requires a lot of hand-polished. The application of laser heat treatment. Laser heat treatment technology is developed in the past two decades a new form surface treatment technology, manufacturing technology for high-power lasers and ancillary equipment increasing in recent years, a variety of surface treatment technologies become more sophisticated, making the laser heat treatment technology of industrial applications and in-depth research is very active. The principle of laser heat treatment technology is a strong penetrating power of the laser-based. The respective advantages of the flash disk transmission and single-chip machine controlling of green laser pointer can be expressed completely.
When the metal surface is heated to just below the melting point of critical transition temperature, the surface rapidly austenitizing and rapid self-quenching, the metal surface quickly be strengthened, namely, laser transformation hardening. Laser heat treatment technology can solve the other surface treatment methods can not solve or not solve the material to strengthen the problem. After laser treatment, the surface strength of the cast layer up to HRC60 degrees of carbon and high carbon steel, alloy steel, surface hardness can reach HRC70 ° or more, thereby to improve their wear resistance, fatigue resistance, corrosion resistance, oxidation resistance and other properties. extending its life. Laser in the welding application. Laser welding is one of the important aspects of laser material processing applications. And then the program should be made to realize controlling of rotation direction and speed of the motor of the green laser pointer system.
The technology has a narrow heat-affected zone, weld, does not require a protective atmosphere, the atmospheric pressure does not produce X-ray beam offset features in the magnetic field does not appear, together with its welding speed and the workpiece without mechanical contact , the magnetic material can be welded, in particular, welding materials and dissimilar metals of high melting point, and do not need to add material, so soon in the electronics industry to achieve the industrialization. Foreign solid YAG laser seam welding and spot welding, and has a very high level. In addition, laser welding the pinout of the printed circuit, without using flux, and reduce thermal shock, had no effect on the circuit die. Japan since the 1990s, in the precision welding of the electronics industry has achieved a shift from spot welding to laser welding. And at the same time, controlling of rotation direction and speed of motor of green laser pointer system can be realized through PWM.
At present, the deep penetration laser welding applications in the field of powder metallurgy materials processing is also increasing. In short, compared with ordinary welding methods, laser deep penetration welding with welding speed, weld depth to width ratio, the heat-affected zone and thermal deformation, weld strength, easy to realize the advantages of automation, so the industry is widely applications. The application of the laser cladding coating. Laser cladding, also known as laser cladding or laser cladding, is a new surface modification technology, which add to the substrate surface cladding materials, and make use of high-energy density laser beam and the substrate surface thin layer with fused. As the bus technology of flash disk develops, the data transmission technology of flash disk is becoming more and more perfect and so does laser pointer .
