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, round 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, which are parts that can be processed by means of stamping, bending, and stretching. A general definition is the parts of the same thickness during the process.
Industry development prospects fold editors
(1) before twentieth Century
The history of the development of sheet metal process has a long history. From the ancient bronze and iron tools, the metal materials were smelted by various methods. With the improvement of smelting technology, metal sheet materials were gradually smelted out, and some tools were used to process these metal sheet materials. This is the sheet metal process. The embryonic form. Before twentieth Century, it was mainly manual sheet metal.
(2) Changzhou sheet metal processing plant from early twentieth Century to 80s
Since twentieth Century, stamping equipment and cold stamping die have been gradually applied in sheet metal processing. By 1980s, CNC sheet metal began to appear. In general, the widespread use of stamping equipment and cold stamping dies and the popularization of CNC automation equipment are the two milestones in the development of sheet metal process. The former was born of stamping and the latter gave birth to numerical control sheet metal.
(3) 1980s to date
Since 1980s, as China has become a world manufacturing center and a big consumer country, the stamping and sheet metal industry, one of the basic industries of manufacturing industry, has also made unprecedented development. And with the development of China's technology, many of the sheet metal processing enterprises and industries are constantly improving, for example, the guidance of laser technology for the development of China's sheet metal processing industry is good.
Although China's sheet metal processing industry has gone to the world and occupies a certain market share among many customers in the world, there is a certain gap between the technology level and the related enterprises in the developed countries, and the key gap is the key gap. The technology service capability is weak, and it can not satisfy the customers' needs in time. With the increasing degree of internationalization of the industry, the leading enterprises in the industry have gradually realized the gap and gradually established a complete manufacturing service system. The gap between the enterprises and the related enterprises in the developed countries has been significantly reduced. The technology of the industry includes two aspects: manufacturing technology and service technology.
The products provided by the sheet metal processing industry have the characteristics of multi variety, multi batch, small batch, non standard and high precision. Therefore, in the manufacturing process, the ability of flexible production, the design ability of process flow and the precision manufacturing ability are required.
