The metal plate part is a forming process of a workpiece (metal plate part) of a desired shape and size by applying an external force to a plate, a strip, a pipe, a profile, and the like by a press and a die to cause plastic deformation or separation. Then we know the meaning of the metal plate parts, then let us know the molding process of the metal plate parts!
Bending: A plastic forming method that bends sheet metal, pipe and profile into a certain angle, curvature and shape. Bending is one of the main processes widely used in the production of Sheet Metal Parts. The bending of the metal material is essentially an elastoplastic deformation process. After unloading, the workpiece will produce a direction of elastic recovery deformation, called rebound. The rebound affects the accuracy of the workpiece and is a technical pipe that must be considered in the bending process.<!--?xml:namespace

Deep drawing: Deep drawing, also called drawing or calendering, is a stamping processing method of using a mold to make a flat blank obtained after punching into an open hollow part. Thin-walled parts of cylindrical, stepped, tapered, spherical, box-shaped and other irregular shapes can be made by the drawing process. If combined with other press forming processes, it is also possible to manufacture parts with extremely complex shapes. In stamping production, there are many types of deep drawing parts. Due to the different geometrical characteristics, the position of the deformation zone, the nature of the deformation, the distribution of the deformation, and the stress state and distribution of the various parts of the blank have considerable and even essential differences. Therefore, the process parameters, the number of processes and the order determination method and the mold design principles and methods are different. According to the characteristics of deformation mechanics, various deep-drawn parts can be divided into four types: straight-walled rotating body (cylindrical part), straight-walled non-rotating body (box-shaped body), curved body (curved surface part) and curved non-rotating body. Types of.
The pull shape is to apply a pulling force to the sheet by the pulling die, so that the sheet material generates uneven tensile stress and tensile strain, and the sheet and the pull mold conforming surface gradually expand until it completely conforms to the pull mold surface. The object of the pull shape is mainly a double-curvature skin with a certain plasticity, a large surface area, a gentle and smooth curvature change, and high quality requirements (accurate shape, smooth flow line, stable quality). The pull shape is relatively low in cost and flexibility due to the relatively simple process equipment and equipment used, but the material utilization rate and productivity are low.
Spinning is a metal turning process. During the processing, the blank rotates actively with the spinning mold or the spinning head actively rotates around the blank and the spinning mold, and the spinning head makes a feeding motion with respect to the core mold and the blank, so that the blank is continuously deformed locally to obtain the desired hollow rotation. Body parts.
