Die Life of cold stamping die and improvements Die Life of cold stamping die and improvements Overview of stamping die Stamping Die - Stamping in the cold, the material (metal or non-metallic) processing into parts (or half) of a special technical equipment, called cold stamping die (commonly known as Die). Press - is at room temperature, using the die installed in the press to put pressure on the material to produce a separation or plastic deformation, and thus to obtain the necessary parts of a pressure processing method. Stamping die in the form of many, the general categories according to the following main features: 1. According to the technical nature of (1) Die along the closed or open contour the material are derived from mold. If blanking die, punch die, cut off the mold, cut mode, cutting mode, split mode, etc. (2) Bending mode to blank or blank sheet along a straight line (curved line) to bend, deform, and thus obtain a certain angle and shape of the workpiece in the mold. (3) The drawing die is made of the blank sheet opening hollow or hollow pieces of further changes to the shape and size of the mold. (4) Die rough or semi-finished workpiece is convex according to plan, direct copy the shape of the die shape, the material itself generate only local plastic deformation of the mold. Such as the bulging mode, reducing the die, expansion die, forming die rolling, flanging mold, plastic mold. 2. According to the degree classification process combination (1) Single process model in a press tour, just completed a die stamping process. (2) Composite model is only one station, in a press tour, at the same station at the same time to complete more than two or two die stam...
