The working principle of tray frame roller forming machine is mainly based on roller forming technology. This technique utilizes the basic principle of metal flow and deformation under pressure, by applying enough pressure to plastic deform the metal sheet under the action of the rolling mold, thus forming the shape of the desired tray holder.
Specifically, the operation process is as follows: First, the metal plate is placed between the upper and lower molds of the tray frame rolling forming machine. Then, through the oil pressure system or air pressure system. As the pressure increases, the metal plate is gradually squeezed, and the plastic deformation occurs under the influence of the shape of the mold. In this process, the lattice structure inside the metal is rearranged to form a tighter shape to resist external forces.
The rolling-forming technology has many advantages. It can produce tray frames with high precision and excellent surface quality, but also can effectively reduce material waste and reduce production costs. In addition, because the whole operation process belongs to the category of cold processing, the material will not produce heat in the processing process, so as to avoid the problem of product accuracy affected by thermal deformation.
However, the rolling molding technology also has its limitations. For example, it is mainly suitable for metal materials with good plasticity and good ductility, while for brittle materials or tray frames with complex shapes, other processing methods may be required.
