【正文】 Second Die Manufacturing Technology with the development of manufacturing technology development of the situation 1. Mold manufacturing technology with the manufacturing equipment and raising the level increase. With the advanced, sophisticated and high degree of automation mold processing equipment applications, such as CNC copy milling machine, CNC machining centers, precision jig grinder, track the number of consecutive Coordinate control of grinding machines, precision low loss CNC EDM machine, EDM wire precision WEDM,ECM precision machine tools, 汽車沖壓件工藝與模具設(shè)計(jì) 第 41 頁 共 46 頁 coordinate measuring instrument, such as extrusion die grinder application processing and testing equipment, expanded Mold can be machined scope to improve the machining accuracy and reduce the workpiece surface roughness, plus greatly enhanced work efficiency, and promoted the development of mold design and manufacturing integration. 2. Mold manufacturing technology with application of new materials, molds increased. Affecting the life of the die mold material, quality,production efficiency and cost an important factor. 3. Mold manufacturing technology with the increased standardization and enhanced. Standardization is representative of die mold industry technology development and an important symbol of the mold. So far, has developed a stamping die, plastic mold, die casting molds and 50 die based technology, a number of national standards, nearly 300 standard number, basically meet the domestic mold production technology made development needs. Degree of standardization is based on the premise of mercialization, with the promulgation and implementation of standards, the degree of mercialization of the mold greatly increased. Promote the mercialization of specialized production, lower manufacturing costs and shorten the manufacturing cycle and improve the standard parts internal and external quality, but also promoted the application of new materials. 4. Die mold manufacturing technology with modern design and manufacturing technology increased. With the puter technology development of applications, puteraided mold design and manufacturing (CAD / CAM) to mature, die design and manufacturing integration technology operation has been achieved. Computeraided design and manufacture not only improve the design speed, but also can shape the simulation, optimal design meter parameters。 design model can be based on the establishment of automated processing, you can also automatically detect the end of processing. third Development Trend of Die Manufacturing Technology As China continues to develop the socialist market economy, increasing the variety of industrial products, product upgrading accelerated an increasingly petitive market. Therefore, improving the quality of the mold and shorten the production cycle is particularly important to promote mold The following trends in technology development. 1. Roughing mold technology to the development of high speed machining. Represented by highspeed milling technology represents a highspeed machining Rough surface of mold shape the direction of development. Highspeed milling can greatly improve the quality of the mold surface, and large greatly improve processing efficiency and reduce processing costs. 汽車沖壓件工藝與模具設(shè)計(jì) 第 42 頁 共 46 頁 Highspeed machining center cutting feed rate of up to 76m/min, Spindle Scooter 45000r/min. In addition, the rough cutting device has highspeed sawing, cutting and laser cutting the anode highspeed,highefficiency processing equipment, there has been a strong highspeed grinding equipment and grinding equipment. 2. Forming the surface of the processing to sophisticated, automated direction. Forming the surface of the processing to the puter control and high precision degree of processing direction. CNC machining centers, CNC EDM equipment, putercontrolled continuous path coordinate grinding bed and dressing assembly with CNC forming and precision measuring devices such as grinding equipment to promote the use, the system is to improve the mold the key to making technology. 3. Finishing technology to automate direction. The current die forming surface grinding, polishing and other processing operations are still mainly by hand, not only to spend hours more, and laborintensive, low surface quality. Industrial countries are being developed by the puter control, autofill with abrasive wear pensation device finishing equipment, can be plex threedimensional surface for surface finishing, and began to mold the use, greatly improving the finishing quality and efficiency. 4. Reverse mold manufacturing engineering technology. To coordinate measuring machines and rapid prototyping technology as the representative of the reverse manufacturing technology, is a kind of copy for the principle of manufacturing has a significant impact. This technology is particularly suitable for multispecies, smallvolume, plex shape of the mold manufacturing, on reduce the die manufacturing cycle, and to improve the market petitiveness of products is important. 5. Die CAD / CAM technology will have a faster development. Die CAD / CAM technology in mold design and manufacturing advantages more and more obvious, it is another mold technology revolution, universal and improve CAD / CAM technology is a manufacturing mold inevitable trend of development. 汽車沖壓件工藝與模具設(shè)計(jì) 第 43 頁 共 46 頁 為你提供優(yōu)秀的畢業(yè)論文參考資料，請 您刪除以下內(nèi)容， O(∩_∩)O 謝謝?。?！ 2 Many people have the same mixed feelings when planning a trip during Golden Week.
