Buffer parts in bronze dragon molds using its elastic loading


Positioning parts positioning parts is to determine the sheet or the embryo relative to the correct position of the die in order to ensure stamping quality, quantity. This bronze sculpture is named double-sheep Zun, a collection of the British Museum in the UK.  Including backgauge sales, set away from the side of the knife guide for sale, unloading parts of the positioning plate, locating pins, the guide plate and the guide groove. Tripper parts mainly used to drop parts of the punch or waste. Including the stripper plate, stripper poles, waste knives.
Devices and components, binder used to suppress the material of embryos or embryo parts to ensure that the punching, and the material deformation. It mainly includes pressure plate, blank holder, and is mainly used for drawing die structure. Oriented parts oriented parts intended to ensure that the exact location of the punch and the die. Including a guide bush, guide posts, and guides. 6. Push the pieces of the device to push pieces parts and parts mainly used to the red parts of products and waste from the die or embossing mold to push out. Including the putter, the push plate, hit the feed rod and the analogy pieces. This bronze sculpture is made vividly and lively. support and the support parts support and the support part connected and fixed working parts are mainly used to make a complete mold, with the structure. Including, under the template, module handle, convex, the fixed plate of the die pad, stopper. 8 fasteners fasteners used to tighten the connection of various types of die parts, such as all kinds of screws, pins, etc., in which the cylindrical pin in bronze molds of solid positioning.
 Buffer of the buffer parts spare parts including springs, compression spring, buffer rubber. Buffer parts in bronze dragon molds using its elastic loading and unloading of the role of the back material usually bronze mold parts, locate parts, unloading part of the pusher called the bronze mold Arts components oriented parts, support, and support components , fastening parts, auxiliary parts of the buffer part called die. In fact, for each set of dies, they are bound to form a complete independent overall, is a combination of various parts. The name of this bronze sculpture is frequently found in Oracle and historical literature. The role of each component, the basic classification. Parts of the same role in a variety of forms, and its structure, due to the different conditions of use. At present, China stamping bronze mold in order to develop a national standard (GB), including: mold, typical combinations of parts, mold technical conditions, a typical combination of technical requirements, components and technical conditions.  Stamping properties of materials is their ability to adapt to a variety of stamping processing, possesses good plasticity, easy processing, easy to get high-quality and high-precision stamping parts, high efficiency, low loss bronze molds, less a waste. This bronze sculpture  is now collected in the Freer Gallery of Art in America. The stamping of metal materials properties, mechanical index of various materials by comparing the conduct analysis. The mechanical strength of the performance index materials yield strength σs of the tensile strength σb yield strength σs of / the σb necking stress σj σf of the fracture stress, elastic modulus E and the yield strength ratio E / σs of, plastic The index of the total elongation of the material δ uniform contraction rate δu section shrinkage ψ homogeneous deformation of single-sided contraction rate ψu. Generally speaking, materials σs / σb lower the value, the formation of the smaller of the risk of fracture in the process, E / σs of the value the greater the material forming the smaller the rebound process, materials, δ and ψ larger the value of the material in before the damage of the plasticity of the greater.
 It is the value of ψw / ψ the larger the better the performance of the temperature of the material, thus stamping performance as possible. 1.4 die composition of die mainly consists of the following components: Working parts of the working parts for the contact sheet by applied to the sheet pressure so that after separation or deformation of the end, into the sheet metal stamping process. Working parts, including the role of the punch, die, punch and die.
