High-precision stamping die convenient to replace

Abstract

The invention relates to the field of dies, in particular to a high-precision stamping die convenient to replace. The high-precision stamping die comprises a horizontally-arranged base plate. An upperdie plate and a lower die plate which are parallel to the base plate are arranged over the base plate and fixedly connected through bolts. Four guiding columns which are vertically arranged and rectangularly distributed are arranged at the top of the base plate, and the upper die plate and the lower die plate are slidably mounted on the four guiding columns in a sleeving mode. Four guiding sleeves which are in sliding fit with the four guiding columns are arranged at the top of the upper die plate. A bearing plate parallel to the upper die plate is arranged over the upper die plate, and the two ends of the four guiding columns are fixedly connected with the base plate and the bearing plate correspondingly. A pressure machine is arranged at the top of the bearing plate, and the top of thebase plate is provided with an adjusting limiting device used for bearing to-be-stamped pieces, and a positioning device used for positioning the to-be-stamped pieces. A stamping device is arranged atthe bottom of the lower die plate. The high-precision stamping die is simple in structure and high in stamping precision, punching demands of the different stamped pieces can be met, the working efficiency is improved, and practicability is high.
