Fine blanking parts, precision of fine blanking technology

Fine blanking parts, fine blanking belongs to a cutting machining technology, is based on the ordinary punching technology developed a kind of fine blanking method. Results of this machining method is washed pieces of blunt section there is no crack on the whole material thickness and tear. In addition, it can achieve the most strict dimension precision straight degree of tolerance of peace. Characteristics of fine blanking parts: fine blanking die structure compared with the general blanking, die structure on a gear ring clamp and ejection device, and minimal convex concave die clearance, die with rounded edge. Before, in the process of blanking punch contact materials, materials by force to make the gear ring clamp pressure on the die, thus in V teeth inside the horizontal lateral pressure, to prevent the material in the lateral flow of metal in the tear and shear area, at the same time of convex die cutting into the material, the use of back pressure of ejector, the material compaction, and using minimum clearance die with rounded corners and eliminates the edge stress concentration, so that the shear zone of the metal in the three-way compressive stress state, to eliminate tensile stress in the district, to improve the material of plastic, fundamentally prevent the ordinary cutting phenomenon of bending, stretching, tearing apart, make the material along the edge shape of die, in the form of pure shear was cutting into parts, in order to gain high quality shear surface smooth, level off. Fine blanking pieces of fine blanking, clamping force, and the rounded edge blanking clearance and concave die supplement each other, be short of one cannot. They are interlinked, the influence of uniform when clearance, radius when appropriate, can be used not big pressure is expected to obtain smooth section.
