Almost all metal forming in the early 20th century was basically done by mechanical and hydraulic presses.With the emergence of roll forming technology, most sheet metal forming that needs mass production is completed by roll forming machine. The advantages of high efficiency and high precision of roll forming have been widely recognized by the market.
The application of roll forming in a corresponding proportion was after World War II, starting from this period, the sheet metal produced by the press was slowly replaced by the roll forming method, so that the production efficiency of sheet metal forming was greatly improved. Reduced production costs.
As a result, roll forming is gradually applied to various fields of life, such as shelves, steel structure buildings, aircraft, electrical appliances, exterior wall decoration, interior decoration and so on.
1. In the 1950s and 1960s, the emergence of rotary encoders made it possible to integrate some auxiliary processing into a production line, such as pre-punching, welding, spraying and other processes, which further improved production efficiency.
2. In the 1970s and 1980s, roll forming rolls could be designed on the computer, making the roll design more flexible, visual, and simulating, making it more accurate and more modifiable.
3. In the 1990s, with the wide application of programmable controllers, the degree of automation and controllability of roll forming was higher. In addition, the roll forming design has been further developed on the computer, so that the material tolerance can be further controlled, and the design is more flexible and changeable.
Therefore, the processing of sheet metal can achieve higher automation, and the quality and production efficiency of products are greatly improved.
This enables sheet metal forming production enterprises to reduce personnel recruitment, and one person can manage the production of one or more machines, which can greatly reduce production costs and enhance the competitiveness of enterprises.
