Safe manufacturing of steel with 14% to 22% chromium and more than 1% carbon steel thin-wall cutting tool or a new application. Here, since the component mass is too low, and the component has a martensitic starting temperature is near room temperature and the end of the temperature is about -10 ℃ material properties, and above the temperature point can reach the target hardness, so the use of traditional laser The hardening process does not guarantee the quality of self-quenching.
Common blue laser pointer processing on the market is reflected in the choice of a good temperature to the parts of the heating, and a certain amount of laser feed to the heat into the steel to achieve the hardening of the final hardness depends on the characteristics of parts and their quality.
High-quality laser hardening treatment based on the variety of steel, independent analysis of alloy composition and determine the state of the quenched and tempered. According to the user's hardening task requirements, to develop a wide range of processing processes. Also included in the scope of work is the sample parts or parts of the tempering and deep cooling. The quality assurance after hardening treatment involves authorizing a partner to use the laboratory quality identification and other technical means to determine the processing results, and through the metallographic method to verify the results.
In the critical context, together with an external material inspection laboratory for the work of the task and the final quality verification and other aspects of the advanced research. At the same time, this cooperation also plays a role in the development of the products required by the user, such as the reliability test of the stability of the tool and the inspection of the cutting capacity in the specific workplace. Only advanced research to make the smooth end of the work, can begin to accept the user parts of the green laser pointer hardening of the commission. Common laser quenching process on the market and a certain amount of laser feed to adjust the tool to achieve the same quality level.
The use of robots to implement laser hardening work, so the application of laser hardening is very flexible. It is only a small amount of preparation work on the equipment components or components to start the laser hardening treatment, and all other laser applications, this hardening method is equally efficient. This technology in the application of the performance of fast, save money, does not depend on any form, can be installed strong, high efficiency and good security. Once the task negotiated, within 24 ~ 36h to complete a single piece of processing. In the commissioning of hardening processing services, the standard range of daily processing tasks is from the small changes in the size of the precision components, until the large pump chassis, rope pulley and hundreds of kilograms of large die for processing. In order to improve component rigidity and reduce component thickness to save material during high quality hardening processes, functional levels such as cutting and quality-free stabilizers are applied. The structural stabilizer is a strong laser pointer trajectory that produces a high rigidity and a low vibration tendency within the component, which can be used in component design concepts and FEM analysis.
A good example of a laser hardening process is the ability to extend the life of the tool on the slaughtering device, which is also the case for the meat cutter. The cutting speed of the tool with the sausage material can reach 700km / h at the time of operation. This kind of thin plate tool will suffer the maximum load such as tapping or vibration during its use. The main load is from the vibration, which is often caused by the fatigue of the material. Cut the tool. Laser hardening can be achieved by laser hardening marks so that the soft tool body becomes stable and hard, thus reducing the probability of tool breakage. The test results show that the laser quenched cutter in the amount of vibration and vibration duration than the overall quenching or quenching of the tool is much stronger.
However, the thin plate tool can not ensure that the quenching process required self-cooling, in this case the need to meet the requirements of the tool quenching method, which developed along the red laser pointer traces of the immediate after the cooling. Thereby successfully achieving the goal of orienting and rapidly cooling the thin-walled material below the starting point of the martensite to ensure a good hardening treatment result. In this way, it is possible to perform a hardening treatment with a sheet with a wall thickness of only 1.5 mm.
