Sheet metal processing technology and material introduction

小梁

Sheet metal processing is a technology that sheet metal technicians must master in the production process, and it is also an important process for sheet metal product forming. Sheet metal processing includes traditional cutting and blanking, blanking, bending and other methods and process parameters, as well as the working principles and use methods of various equipment, various cold stamping die structures and process parameters, as well as new stamping processes and new processes .

Sheet metal processing, specifically, is to use sheet metal to manufacture chimneys, iron drums, oil tanks, ventilation ducts, elbows, circular places, funnels, etc. The main processes include shearing, bending and trimming, welding, riveting, etc. Sheet metal parts can be processed by stamping, bending, stretching, etc., and are usually defined as parts with constant thickness during processing. The corresponding parts include castings, forgings, machined parts, etc.

Select sheet metal fabrication material:
Sheet metal processing:Commonly used materials are cold-rolled sheet, hot-rolled sheet, galvanized sheet, copper brass, red copper, beryllium copper, aluminum sheet, stainless steel. According to different product functions, different materials are selected, and the use and cost of the product are generally considered.
1. Cold-rolled sheet SPCC is mainly used for electroplating and baking. It has the characteristics of low cost and easy forming, and the material thickness is 3.2mm.
2. Hot-rolled sheet SHCC, material T3.0mm, is also used for electroplating and baking parts. Its cost is low, but it is difficult to form, and flat parts are mainly used.
3. SGCC Secco galvanized steel sheet. SECC electrolytic plate is divided into n material and p material, n material is mainly without surface treatment, and the cost is high; p material is used for spraying parts.
4. The surface treatment of copper and conductive materials is nickel-plated or chrome-plated, which is expensive.
5. Aluminum plate, commonly used surface chromate, oxidation, expensive, silver-plated, nickel-plated.
6. Aluminum profiles, materials with complex cross-sections are widely used in seed boxes, and their surface treatment is the same as that of aluminum plates.
7. Stainless steel, without any surface treatment, expensive.
Sheet metal processing steps are: product pre-test, product trial production, product mass production.
In the process of product processing and trial production, it should communicate with customers in a timely manner, and after obtaining the corresponding processing evaluation, mass production should be carried out. In the laser material processing technology, laser drilling is the earliest practical laser technology. Laser drilling in sheet metal workshops generally uses pulsed lasers, which have high energy density and short time, and can process small holes of 1m, especially suitable for processing small holes and thin materials at a certain angle, and also suitable for processing high strength and high hardness. Deep and tiny holes in parts or brittle soft materials. The use of laser can realize the drilling of gas turbine combustor parts, and the drilling effect can be realized in three dimensions, and the number can reach thousands. Materials that can be stamped are stainless steel, Inconel and Hastelloy.
With the development and improvement of laser drilling technology, the laser cutting machine has realized automatic operation. Apply it to the sheet metal industry to realize unmanned operation and change the traditionalSheet metal processing:In this way, fully automatic operation is realized, which greatly improves production efficiency, promotes the development of sheet metal economy, improves stamping effect by a grade, and achieves obvious processing effect.
