Station level in many of the research and development trend of the status quo 1.1 Many station level in the course of Many station level in the course is normal to be set up on the basis of a kind of high-precision and efficiency, long service life of the mold and technology intensive die of a development direction of progressive metal stamping tooling.This stencil off for a hole in the work, but according to the parts of the structure of the characteristics and properties, forming down and washed, bent, deep and concrete step, and even in the process of assembling the machine mold.The ram, with material or section of the mold into the entrance to the end, and to strictly control step from the conditions in accordance with the concrete process of order, through various station of the ram, in the final cut down or station fnx, it will be charged with the product requirements pitch out the matter.To ensure more station level of the normal work in high precision tool must be oriented and accurate it is equipped with automatic system, material and automatically send out, the security device detection and.So many station level in the course of the ordinary classes of punches more. compared with the following special features:33654
    （1）In a tool that can be completed, including at the deep and shape, and more stamp out the operation less ; use more than vice die turnover and positioning process, significant increase their productivity and equipment utilization some.
    （2）As in the process can be dispersed into the course in different station, it is not a composite of the "issue" mw minimum wall design molds is adjustable to strength and molds assembly needs to leave vacant  to ensure that the strength of the mold and assemble space.
    （3）Many station level in the course usually have a high accuracy in addition, external oriented ( be a guide for high precision, it must be implemented in a tiny )and correct guidance to protect it from the system to ensure the products of the part of precision and stencil processing life.
    （4）Station level in more often used at very high speed up production of the ram, mold adopted to automatically, a detection and automation, security and safety of operation, high efficiency.At present, the world's advanced level in the course of many station, station for more than 50 multiple to stamp out the speed of time in more .
    （5）Station level in more complicated in structure, of course, together with the demanding, mold manufacture, debug and maintain a certain degree of difficulty.To mold both parts of exchange. on mold parts worn or damaged after asking for change rapidly and convenient and reliable mould tool. therefore, work must be parts timber assortment (often used of high strength of steel, alloy steel tool with or exhibitions and other materials ), we must take care of application processing and pelletized thread cutting, grinding and coordinate, coordinates worn for the chamber process manufacture of mould advanced.
（6）Many station level is primarily used to be rushed into the thickness of a thin (do not usually exceed 2mm ), production big and shaped complex and require a high precision, small parts. this tool at the parts and components for it10 level.
