Plate roll forming is an important metal forming process, its working principle is based on the sheet or strip through a series of special shapes of the roll, plastic deformation under pressure to form the desired section shape. This process is flexible and efficient, especially suitable for mass production of complex profiles.
During the roll forming process, the sheet is first fed into the mill and then passed through multiple pairs of continuous forming rolls. These roll molds have specific shapes, and when the thin plate passes through, they will gradually bend and deform under the extrusion of the roll die until the predetermined section shape is reached. Roll forming can achieve continuous forming, without heating and softening of the metal, thus reducing the production cost.
The flexibility of roll forming is reflected in many aspects. First, it can produce products of different shapes by adjusting the shape and position of the roll mold. Secondly, the rolling forming can also integrate drilling, pressing, cutting and other subsequent processing into the same production line, to improve the production efficiency. Furthermore, the process has no limit on the length of the product and is capable of producing products of arbitrary length.
The rolling forming process is widely used in automobile, construction, office furniture, home appliances and household products and other industries. For example, car body components, building doors and Windows hardware, metal frames of office furniture, etc., can be produced efficiently and accurately through the roll forming process.
In short, the sheet roll forming process plays an important role in the field of its high efficiency, flexibility and low cost. Through continuous technological innovation and improvement, the roll forming process will further expand its application scope to meet the needs of more industries.
