How To Choose Sheet Metal Stamping?
For some commonly used appliances in life: chimneys, iron barrels, fuel tanks and oil cans and other specific objects, the primary process of Sheet Metal Processing is some cutting, riveting, bending, welding, bending and so on. However, the specific process flow of sheet metal parts according to different structures is also different.
Sheet metal processing process: it is to make a general plan for the sheet metal parts → the second is to draw according to the specific skills of the sheet metal parts → then to make an open drawing, that is, CNC programming → the next thing is to proceed The material can also be said to be a number of punching operations → followed by the next step for bending → then the sheet metal processing parts for pressure riveting operations → then came to the welding sheet metal processing parts → and then the surface of the sheet metal processing parts. The specific beautification treatment, for example: spraying or electroplating → finally, silk screen printing to installation and packaging and shipping, the above is the most basic process introduction of the entire sheet metal processing.
1. Galvanized sheet
The base material of the galvanized sheet is a common cold-rolled steel coil. After the continuous phosphating production line undergoes deoiling, pickling passivation, electroplating and various post-treatment processes, it becomes a phosphating product. It not only has the physical properties and similar process properties of ordinary cold-rolled steel sheets, but also has excellent corrosion resistance and decorative art appearance. There is considerable competition and substitution in the sales market of electronic equipment, Household Appliances and furniture.
2. General cold rolled steel plate
Cold-rolled steel plate refers to the continuous cold-rolling of steel castings by cold-rolling mills into thick steel plates or scraps of specified thickness. There is no safety protection on the surface. It is very easy to be oxidized by air when exposed to gas. Especially in the humid and cold natural environment, the air oxidation rate is accelerated, and dark red rust appears. The surface should be sprayed, electroplating or other safety protection during application.
3. Hot-dip galvanized thick steel plate
Hot-dip galvanized steel coil refers to the processing of semi-finished products after hot-rolling pickling passivation or cold-rolling, after cleaning, quenching, and infiltration into a molten zinc bath with a temperature of about 460 ° C, and then the steel plate is inlaid with a zinc layer, and then undergoes heat treatment. Smoothing and organic chemistry solution. The raw material is harder than the raw material, the plasticity is poor, the zinc layer is thicker, and the arc welding ability is poor.
4. 304 stainless steel
One of the most commonly used stainless steels, because it contains nickel, it has better corrosion resistance and temperature resistance than steel containing chromium, and has good physical properties, no quenching and tempering treatment, and no ductility.
5. 301 stainless steel
The water content of chromium is lower than that of 304, and the corrosion resistance is weak, but after cold drawing, it can obtain very good tensile strength and strength in stamping parts processing, and has good ductility.
