Punching die has been widely used in industrial production. In the traditional industrial production, the worker work very hard , and there are too much work , so the efficiency is low . With the development of the science and technology nowadays , the use of punching die in the industrial production gain more attention , and be used in the industrial production more and more . Self-acting feed technology of punching die is also used in production , punching die could increase the effici6891ence of production and could alleviate the work burden , so it has significant meaning in technologic progress and economic value.6891

1.The mold designing and manufacturing
The mold is the manufacturing industry important craft foundation, in our country, the mold manufacture belongs to the special purpose equipment manufacturing industry. China although very already starts to make the mold and the use mold, but long-term has not formed the industry .Straight stabs 0 centuries 80’s later periods, the Chinese mold industry only then drives into the development, the three investments enterprise, the villages and towns(inpidual) the mold enterprise’s development also rapid quietly.
Although the Chinese mold industrial development rapid, but compares with the demand, obviously falls short of demand, its main gap concentrates precisely to, large-scale, is complex, the long life mold domain. As a result of in aspect and so on mold precision, life , manufacture cycle and productivity , China and the international average horizontal and the developed country still had a bigger disparity , therefore , needed massively to import the mold every year.
The Chinese mold industry must continue to sharpen the productivity , from now on will have emphatically t the profession internal structure to center the upscale mold development , to the import and export structure improvement , center the upscale automobile cover mold forming analysis and the structure improvement , the multi-purpose compound mold and the compound processing and the laser technology in the mold design manufacture application , the high-speed cutting , the super finishing and polished the technology , the information direction develops.
The recent years , the mold profession structure adjustment and the organizational reform step enlarges , mainly displayed in , large-scale , precise , was complex , the long life , center the upscale mold and the mold standard letter development speed is higher than the common mold product ; the plastic mold and the compression casting mold proportion increase ; Specialized mold factory quantity and its productivity increase ; “The three investments” and the private enterprise develops rapidly ; The joint stock system transformation step speeds up and so on . Distributes from the area looked , take Zhejiang Delta and Yangtze River delta as central southeast coastal area development quickly to mid-west area, south development quickly to north . At present develops quickest , the mold produces the most centralized province is Guangdong and Zhejiang , places such as Jiangsu , Shanghai , Anhui and Shandong also has a bigger development in recent years .
2.Mold Present Status of Technology
Technical level of China’s mold industry currently uneven , with wide disparities generally speaking , with the developed industrial countries , Hong Kong and Taiwan advanced level , there is a large gap.
3.Die Trend
(1)Mold software features integrated
Die software features of integrated software modules required relatively complete , while the function module using the same data model , in order to achieve Syndicated news management and sharing of information to support the mold design , manufacture , assembly , inspection , testing and production management of the entire process to achieve optimal benefits .
(2)Mold design , analysis and manufacture of three-dimensional
Two-dimensional mold of traditional structural design can no longer meet modern technical requirements of production and integration . Mold design , analysis , manufacturing three-dimensional , intuitive sense to design the mold , using three-dimensional digital model can be easily used in the product structure of CAE analysis , tooling manufacturability evaluation and CNC machining , forming process simulation and information management and sharing .
