Metallurgical Quality of Die Steel by Metal Laser Cutting Sheet Metal Processing

Release date:2016-07-27

1. Metal laser cutting sheet metal processing smelting quality About high quality mold (referred to as: the mother of the industry) steel, widely used outside the furnace refining, vacuum processing (chǔ lǐ), vacuum smelting, dusting treatment (chǔ lǐ), electricity Process such as slag remelting, reducing the specific gravity of harmful elements in steel, oxygen, hydrogen and inclusions, and fine-tuning the chemical composition and pouring temperature.




Shanghai Jinjin processing technology, sheet metal has not yet had a relatively well-defined definition. According to a definition in a foreign professional journal, it can be defined as: sheet metal is a generalized cold processing process for metal sheets (usually below 6mm), including shearing, punching/cutting/compositing, folding, riveting, Stitching, forming (such as car body).




Shanghai sheet metal processing is becoming more and more widely used with sheet metal. The planning of sheet metal parts has become an important part of the product development process. It is necessary for mechanical engineers to master the planning skills of sheet metal parts and make planning Gold not only satisfies the requirements of the product's function and appearance, but also makes the stamping die simple to manufacture and low in cost. After (tōng guò) electroslag remelting can also effectively improve the low-order arrangement and density of steel, and improve the isotropic properties of the steel mold (referred to as the mother of the industry). Experiments in some domestic production plants show that the lateral impact toughness value of 4Cr5MoSiV1 steel produced by electric arc furnace is only equivalent to 31 in the longitudinal direction. After 4Cr5MoSiV1 steel in the future electroslag remelting, the transverse impact toughness value can be equivalent to the longitudinal direction. 70, the progress is more than 1 time. Regarding the special requirements of the mold steel, the powder high-speed steel and the powder high-alloy mold steel produced by the powder smelting metal process can be used to better improve the arrangement and function of the steel.

2. Metal laser cutting sheet metal processing Casting and rolling process On the basis of ensuring a certain casting ratio, as much as possible, the upsetting and drawing process and the interpenetrating rolling process are used to improve the mold (name: industrial mother) material (Material) Isotropic.




Shanghai Sheet Metal has the characteristics of light weight, high strength, electrical conductivity (can be used for electromagnetic shielding), low cost, large-scale mass production, etc. It has been widely used in the fields of electronics, telecommunications, automotive industry, medical equipment, etc. In computer cases, mobile phones, and MP3s, sheet metal is an essential part. In order to maximize the reduction of machining allowance and improve the utilization rate of materials, a wide selection of precision forging machines, fast forging water pressure (specifically: pressure) machines, high-precision continuous rolling mills, and high-precision steel-adapted molds are used. : The mother of industry) needs to make.
