If it is fine blanking, the gap is basically very small, ranging from 0.5 to 3 wires, depending on the thickness of the material.
The softer the material, the smaller the gap.
Extended data:
According to the process nature, it is divided into blanking die, bending die, drawing die, forming die and riveting die.
1. Die: A die that separates materials along closed or open contours. Such as blanking die, punching die, cutting die, cutting die, trimming die, cutting die, etc.
2. Bending die: a die that bends a blank or other blank along a straight line (bending line) to obtain a workpiece with a certain angle and shape.
3. Drawing die: it is a die that makes blank plates into open hollow parts or further changes the shape and size of hollow parts.
4. Forming die: it is a die that directly replicates and forms a blank or semi-finished workpiece according to the shapes of the punch and the die, and the material itself only produces local plastic deformation. Such as expanding die, necking die, flaring die, wavy forming die, flanging die, shaping die, etc.
5. Riveting die: the participating parts are connected or lapped together in a certain order and manner by external force, thus forming a whole.
