1mm. NextpageOpengate and technology of forming machine of Opengate of Geotack forming machine are the product that Italian COMAU company rolled out 1993, advocate if rely on to control lateral tool,have fixed position to automobile body, the robot does not share fixed position, undertake soldering only. Pass those who control lateral tool to change, realize a variety of models to be in same work production is this forming machine flexible manufacturing principle, up to now this technology already passed 5 acting technologies to evolve. Because tool of lateral of Opengate forming machine changes faster (walk orgnaization speed 2m/s) , the robot undertakes soldering only, productivity is strong, can amount to the productivity of 48 ～ 55V/H most. Orgnaization of fixed position of a complete set of is located by tool of left, right lateral, bottom tool, roll bed and automobile body automatic spiral lifting device is formed. If the graph is shown 5 times,specific orgnaization is comprised. The tigidity of tool is better, not easy generation is out of shape, firm and reliable, location is relatively exact. The lateral tool of forming machine of Opengate of composition of structure of graph 5Opengate forming machine moves all right through stack form, the lateral tool that can realize a variety of models changes (see a picture 6) , but the area is covered an area of when much breed bigger, need reasonable consideration position. Graph the lateral tool of a variety of 6 models changes the solder that waits for Motor Corporation in FIAT, GM, FORD installs technology of Opengate forming machine product line figuration is versed in be used in great quantities, in me plan of early days of company X7 project seeks advice from a process in, technology of this forming machine also as await choose plan to attend bid. Technology of Geotack forming machine is the product of German ETAG company, the working mode that its model alternates and Opengate are more similar, the changeover that also is support lateral tool will realize same work flexible production. Of this forming machine and Opengate lie differently to use independence with its lateral tool retroflexion type tool adds up to outfit orgnaization, the structure of tool is designed very firm is stable, the geometrical dimension that makes automobile body locates gets effective assurance. Geotack forming machine can be in at most same work those who realize 6 kinds of models is flexible production, the changeover platoon of its lateral tool has intelligence to change more on cloth, whole industry 18m is in direction of transmission line length, width is 14.
5m, cover an area of area ratio Opengate small. Because technology of this forming machine has manufacturing metre big, model is flexible had changed, geometrical dimension stability and later period model guide to showing production affects lesser characteristic, because this is in,the large Motor Corporation such as the masses is used extensively. The comparative above of technology of a few kinds of forming machine a few kinds of forming machine are more mature technology, the practice that producing got test and verify in the process, but be aimed at different use and demand situation, have respective adaptability again. Oneself make a simple contrast according to the use situation that understand and produces now (detailed sees next tables) . Forming machine contrast expresses the development as auto industry, increasing to the demand of model breed appearance influences the market, onefold breed is in of the market have rate proportion also decreasing stage by stage, this makes before mode of production of car of onefold, tall metre gets used to force to breed diversity, market stronger orientation develops, this makes Flex Framer and Body Flexor have definite advantage more than Geo Flexor, as to Opengate and Geotack technology, because suffer the effect that covers an area of an area, because this has certain limitation, these also are divine dragon companies the main reason that the X7 in later period and BX3 choose technology of Bodyflexor forming machine in two new projects.
