Sheet metal forgings and its welding
Technology NewsFor many sheet metal processing, because a lot of processing needs to be done for sheet metal parts, especially in the cooling process of parts, the type, cooling performance and hardenability of quenching medium in sheet metal processing are related to deformation. The change of cooling performance can be adjusted by changing the viscosity, temperature,…
How to judge the quality of laser cutting sheet metal parts?
Technology NewsRoughness. The laser cutting section will form vertical lines, and the depth of the lines determines the roughness of the cutting surface. The shallower the lines, the smoother the cutting section. Roughness not only affects the appearance of the edge, but also affects the friction characteristics. In most cases, it needs to be reduced as…
What details should be paid attention to in the processing of sheet metal cabinet?
Technology NewsAt present, in the processing industry, sheet metal cabinet processing is one of the more prominent processing forms, because the sheet metal cabinet products with good strength and long service life can well protect the sheet metal cabinet equipment, so as to prevent any damage to the inner parts. However, in order to better ensure…
A summary of some bending elements
Technology NewsBending is a stamping process that uses pressure to force the material to produce plastic deformation, so as to form a certain angle and curvature shape. Common bending includes V-shaped bending, Z-shaped bending and reverse bending. The following is a summary of some bending elements ： Bending height The bending height shall be at least…
Quality and specification of grinding
Technology News1) Grinding and polishing quality After grinding, the surface of the parts shall be free of unevenness, burr, concave hole and trachoma. After polishing, the overall surface shall be smooth. The surface of stainless steel products or welding parts(custom sheet metal parts) shall be treated with XX mesh wire drawing. After wire drawing, the wire…
Development and application of sheet metal manufacturing industry
MFG NewsSheet metal manufacturing is the blanking or cold and hot forming of sheet metal materials, aluminum profiles and pipe fittings without changing their cross-sectional characteristics. Then the assembly is carried out by means of electric welding, riveting and screw connection, and the production and manufacturing mode of the specified metal structure is produced. The key…
Difficulties in aluminum welding
Technology NewsVery easy to oxidize. In the air, aluminum is easily combined with oxidation to form a dense aluminum oxide film (about 0.1-0.2um thick) , the melting point is high (about 2050 ℃), far exceeding the melting point of aluminum and aluminum alloys (about 600 ℃). The density of alumina is 3.95-4.10g/cm3, about 1.4 times that…
