As a whole, the sheet metal industry has developed rapidly in recent years. Sheet metal processing is called sheet metal processing. For example, making use of plate to make chimneys, iron buckets, oil tank oil pot, ventilation pipe, big head of elbow, Tianyuan place, funnel shape and so on. The main working procedure is cutting, bending and buckle edge, bending forming, welding, riveting and so on. It needs certain geometric knowledge.
Sheet metal parts are sheet metal parts, that is, parts that can be processed by means of stamping, bending and stretching. A general definition is that parts with constant thickness in the process are casting parts, forgings, machined parts, etc., for example, the iron shell outside the steam car is a sheet metal piece, some stainless steel is made. The cabinet is also a sheet metal.
The materials used in sheet metal processing are cold rolled plate (SPCC), galvanized sheet (SECC), copper plate, aluminum plate, stainless steel plate, aluminum material and so on. The function of the sheet metal is different. As for how to choose, it should be considered from its use and cost. This is mainly due to the following reasons: the increase of production capacity. China has increasingly become an international manufacturing and manufacturing center, coupled with increasing foreign investment.
The precision of the sheet metal processing punching is about + 0.1mm, and the bending precision can generally reach to + 0.5mm. Therefore, compared with the sheet metal processing, the precision is much lower and the profit is high, such as the stamping can reach about 30%, and the laser cutting can reach 50% or even more.
The ability demand of metal processing is increasing, and the electrical control box and machine shell in the metal processing industry are generally sheet metal parts, so the demand for sheet metal processing ability is also increasing, the processing precision is low, and the upper hand is easy.
As far as sheet metal processing is concerned, accuracy is very common in several threads, and the complexity of the process is relatively high. Even some parts work in dozens of ways. Therefore, sheet metal processing enterprises usually need a variety of mechanical equipment to meet different technological requirements.
