Description

Automatic regulation and control side coaming device of multi-point die Technical Field The invention relates to the technical field of dies, in particular to an automatic regulation and control side coaming device of a multipoint die. Background The multipoint mould is arranged through a plurality of pressure heads with adjustable heights to form a multipoint forming mould, the heights of different pressure heads can be adjusted according to the curvature of a workpiece, and the principle that a plurality of points form a surface is utilized to obtain a required curved surface shape so as to meet the requirements of stamping forming of workpieces with different curved surface shapes. The number of dots per unit area determines the quality of the component surface. The smaller the number of points is, the smaller the contact area between the workpiece and the workpiece is, the lower the forming curvature precision of the workpiece is, and defects such as indentation, rebound, wrinkling and the like are easy to occur. The more the number of points is, the larger the contact area between the workpiece and the workpiece is, the higher the precision of the forming curvature of the workpiece is, and the lower the probability of defects is. However, the larger the number of points is, the smaller the overall dimension of the pressure head is, the capability of the single pressure head for independently bearing load is weakened, and particularly when a workpiece with large curvature is pressed, the pressure head is required to bear the impact force in the vertical direction and also bear larger transverse component force, and the pressure head is easy to deform or damage due to insufficient transverse rigidity. Therefore, an automatic regulation and control side wall plate device of a multipoint mould is provided to solve the problems.
