Processing Knowledge Sharing Material Selection Method for Sheet Metal Processing


Sheet metal processing is a comprehensive cold-drawing process, mainly including: cutting, stamping, folding, joining, riveting, assembling, forming, etc.In general, the basic equipment of sheet metal processing plant includes shearing machine, CNC machine tool, water cutter, bender and various auxiliary equipment, such as uncoiler, leveler, deburring equipment, nut spot welder, etc.Generally, the three key processes in a sheet metal mill are cutting, stamping and folding.For example, sheet metal processing equipment, if people want to produce a batch of stainless steel plates and shells, they must first use a shearing machine to cut the sheet metal to the required size.CNC machines and water jet cutters can be used if required.The sheet metal is further produced and processed into the required shape design, and then folded into the necessary housing parts with a bender, then welded, metal surface treatment, etc.What large and medium-sized mechanical equipment is required for sheet metal processing?Basic capabilities with the following equipment open small and medium sheet metal processing plants.1. Mechanical equipment: bender, cutting machine, four-roll bender, high-speed punch.2. Electric welding equipment: butt welder, second shield welding, argon arc welding.3. Laser cutting equipment: grinding wheel cutter, polishing machine, gas plasma cutting.4. Other equipment: air compressor, bench drill, polishing machine, spraying equipment, etc.So, what equipment do people use in their daily life?For example, sheet metal processing of air-conditioning outdoor chassis, sheet metal processing of metal trash bin, laser cutting of sheet metal parts of automobile housing, laser cutting of electric cabinet, door control box, service terminal shell, sheet metal processing of outdoor switch box, sheet metal processing of mechanical equipment shell, production and processing of environmental protection equipment shell, sheet metal processing of metal material storage cabinet of office equipment.In short, sheet metal processing is only cutting, stamping, folding and welding.A common sheet metal factory has a shearing machine, a high-speed press, a bender and two welding machines, plus some common polishing machines, as well as cutting, grinding and polishing.The actual choice depends on the commodity manufacturing industry to be manufactured.High-precision sheet metal processing must be CNC processing equipment, while conventional sheet metal processing equipment that is too low may be.

Generally, sheet metal processing materials are mainly divided into the following: stainless steel, copper, aluminium and other materials. Different types of sheet metal materials need to be processed in different ways and used in different ways.

1.1. Stainless steel plate.

(1) Cold rolled steel plate.Cold-rolled steel plate is mainly a kind of steel plate which controls the room temperature and is lower than the recrystallization temperature and then is rolled and thinned.Cold rolled steel plate.Its smooth surface and uniform thickness make it easy to shape and cost-free. It can be painted or plated, thus expanding the application range of steel plate.

(2) Hot-rolled steel plate: This steel plate treatment method is mainly to treat the blooming or cast slab, heat it and then remove phosphorus to form the roughly rolled steel plate.Generally, there is a slight deviation in the thickness of hot-rolled steel plate, and there may be a Hemping problem during the actual treatment.Hot-rolled steel plate treatment process is mainly used in the production of spare parts for vehicles, bridges, ships and other equipment.

1.2. Galvanized sheet.Galvanized sheet is mainly galvanized on the surface of steel plate.Generally, it is necessary to control the galvanizing layer thickness of steel plate to 10μM or more, which can prevent the surface of steel plate from being corroded and other damages. It is mainly used in parts which have great requirements for corrosion protection.
