Sheet metal processing technology: According to the basic processing methods of sheet metal parts, including cutting, bending, stretching, forming, and welding.

Cutting: Cutting can be divided into general punching, numerical punching, shearing machine cutting, laser cutting, and wind cutting according to different processing methods. A different processing methods, the processing technology of cutting also varies. Metodos principales cutationis metallis processationis lapides puncti sunt et laser cutatis sunt. Quando materiales bending, layer exterior extentur, quando layer interior in area anguli rotunda compressa est. Quando densitudo materiae constantia est, minor interiorem, graviorem extentum et compressionem materiae; When the tensile stress on the outer fillet exceeds the ultimate strength of the material, cracks and fractures will occurre. Therefore, the structural design of bent parts should avoid excessively small bending fillet radii.

Stretching: The fillet radius between the bottom of the stretching part and the straight wall should be greater than the plate thickness, i.e. r1 t. In order to make the stretching process smoother, r1=(3-5) t is generally taken, and the maximum fillet radius should be less than or equal to 8 times the plate thickness, i.e. r18t. The thickness of the stretched material will change due to the various levels of stress applied at different locations. In general, the bottom center maintains its original degree, the material at the rounded corners of the bottom becomes thinner, the material near the flange at the top becomes thicker, and the material at the rounded corners around the rectangular stretching part becomes thicker.

Forming: Pressing ribas on plate-shaped metal parts helps to increase structural rigidity. Louvers are usually used on various covers or casings for ventilation and heat dissipation. The forming method is to cut the material with one edge of the convex mold, while the rest of the convex mold simultaneously stretches and deforms the material to form a undulating shape with one edge open.

Welding: Welding methods mainly include arc welding, slag welding, gas welding, plasma arc welding, fusion welding, pressure welding, and brazing. Welding of sheet metal products mainly includes arc welding and gas welding. Arctura fluctum habet, manerabilitatem, et amplius applicabilitatem, et potest ad omnem plagam positionem utilizat. Instrumenta utilita est avantias simplicitatis, bonae durabitatis, et minimas conservationis. But the labor intensity is high and the quality is not stable enough, which depends on the operator's level. Temperatura flammae et propalitatibus petrae quam in petra quam in petra quam in petra quam in altum quam in altum quam in altum quam in altum quam in altum quam in altum quam in altum quam in altum quam in altum quam in altum quam in altum quam in altum quam in alterum graduum potest adjustabilur.

The results should be consistent, and the final results should be based on the final destination.
