There are many types of metal stamping parts and metal stamping processes, and the manufacturing level and shape of the stamped parts produced by each process will vary greatly. What is metal stamping technology and what are its detailed processes?

The metal stamping process can be divided into two categories: separation process and forming process. The purpose of forming technology is to cause plastic deformation of the sheet without damaging the billet, so that the workpiece has the desired shape and size. The separation process, also known as punching, aims to separate stamped parts from sheet metal along a certain contour line while ensuring the quality requirements of the separated section. In actual production, many processes are often applied to workpieces. Punching, bending, shearing, stretching, bulging, spinning, and straightening are several main stamping processes.

Design process drawings for machined parts

Design and draw three parts of a hardware workpiece, whose function is to express the structure of sheet metal parts through drawing. Draw the unfolded diagram of the workpiece, which means unfolding complex parts into flat parts. Analyze the part drawing, quickly understand the positional relationship between the dimensions, coordinate points, lines, curves, and cutting surfaces of the workpiece, determine the coordinate origin of the workpiece, and calculate the coordinates of each vertex and curve connection point.

Efficient selection of cutting methods

The bottom of the scissors is the length and width of the scissor shape. If there are punching and cutting angles, punching and mold punching are combined to form cutting angles. The bottom surface of the punch press is a flat sheet structure, used for flushing parts after one or more steps of unfolding. Its advantages are short working hours, high efficiency, and it is commonly used in mass production. Use programming software to develop drawings into recognizable content for CNC machining machines.

Production stamping sequence

Metal stamping parts generally have processing procedures, such as cutting corner materials, cutting convex shells, punching and tearing, etc., and processing requires corresponding molds to complete the operation. In addition, the bending process also requires a bending bed and corresponding bending molds to complete the operation. The design principle is to prioritize the next step of operation without interference.
