The function and type of metal stamping dies in hardware processing plants

by:QY Precision      2020-04-09
In the hardware processing factory, the metal stamping die is a special process equipment for processing materials into parts. The metal stamping parts are processed by the metal stamping die, therefore, you may be unfamiliar with metal stamping dies. About the role of metal stamping die 1: metal stamping forming die is to directly copy and form the blank or semi-finished workpiece according to the shape of the drawing and the concave die, the material itself only produces molds with local plastic deformation. Such as expansion die, shrinkage die, expansion die, undulating forming die, flanging die, shaping die, etc. Function 2: The metal stamping drawing die is a die that makes the sheet blank into an open hollow piece or further changes the shape and size of the hollow piece. The bending die makes the sheet blank or other blank follow the straight line (Bending line) A mold that produces a bending deformation to obtain a workpiece with a certain angle and shape. Function 3: The materials processed by stamping parts are mainly hot rolled or cold rolled (Mainly cold rolling) The metal plate with materials, such as carbon steel plate, alloy steel plate, spring steel plate, galvanized plate, tinned plate, stainless steel plate, copper and copper alloy plate, aluminum and aluminum alloy plate, etc. Stamping is generally not generated by chips, the material consumption is less, and no other heating equipment is needed, so it is a material-saving and energy-saving processing method. About the process type of metal stamping die 1. The single-process mold only completes the mold of one stamping process in one stroke of the press; 2. The composite mold has only one station, and two or more stamping processes are completed simultaneously at the same station in one stroke of the press; 3. Progressive Die (Also known as continuous die) In the direction of blank feeding, there are two or more stations, and two or more stamping processes are completed one by one at different stations in one stroke of the press; 4. The blanking die produces separate molds for the material along the closed or open contour line, such as blanking die, punching die, cutting die, cutting die, edge cutting die, cutting die, etc; 5. The drawing die is a die that makes the sheet blank into an open hollow piece, or further changes the shape and size of the hollow piece; 6. The bending die makes the sheet blank or other blank follow the straight line (Bending line) A mold that produces a bending deformation to obtain a workpiece with a certain angle and shape; 7. The forming die is a die that directly replicates the blank or semi-finished workpiece according to the shape of the convex and concave die, while the material itself only produces local plastic deformation. There are many processing techniques in the hardware processing factory, but it is necessary to learn to understand the metal stamping die.
