Precision stamping mould stripping plate structure is how to design, please

Precision stamping production succeed without reasonable mould design and production, and we tend to be more easy to overlook the stripper is also a key, the reasonable structure of stripper is one of the normal operation of mould on the basis of. Stripper in addition to the stripper, sometimes collapse together with punch guide plate, a direction and protect the punch, precision stamping parts of the stripper stripper size and shape analysis of appearance is more similar to the shape of upper and lower mold base of progressive die, for rectangular and circular commonly two kinds. Precision stamping parts of the thickness of the stripper and blanking sheet thickness and the width of the stripper is also relevant. Second, precision stamping forming hole in the stripper design precision stamping forming hole in the shape of a stripper basic is the same as the shape of the blade. Therefore, should cooperate with blade machining. However, when designing stripper forming holes should be paid attention to the following: 1, with the punch and stripper hole clearance (C Unilateral) Numerical, generally to C = ( 0. 1 to 0. 5) t; And elastic stripper plate C = 0. 1 to 0. 2) T, or press H8 / h7 coordinate values. 2, if the stripper to guide the punch is at the same time, the fit clearance need to press the H7 / h6 to cooperate. 3, the upper and lower installation of stripper joint surface should be smooth general grinding machine processing should be adopted, in contact with the material on the surface of the hole can not chamfer, while the other side should be chamfering C0. 5. 【 Relevant recommendation 】 Details: how much do you know the new energy automotive stamping parts?
