【正文】 punching process of conveyors, Narrows the operators and stamping area, is to save investment and energy consumption extremely good measures, so stamping manufacturers can put punching process reduce vehicle number design as the important way to manufacture cost, even ? Modern stamping development and research of the major subjects include: (1) module type and control。 (3) special stamping technology。 and virtual (5) die amp。 (2) due to its strip for belt and masking belt device, can save another set feeding blanking process, (3) achieved great work pieces the nonstop machining, (4) can both independent and can bee series of control bination dies action can continually stamping processing。joint processing, also in two sides stamping workpiece machining, which has greatly enhanced the work efficiency, have data show that the module type stamping makes processing cost can fall to 40% 50%. The current module type stamping device integration is very high, in width is 300MM size range can arrange of 35 mold, through the roof top of stamping die for independent type series of control, is formed namely die of integrated control. The whole system programmable in WINDOWS user interface and menu under implementation, programming involves mould along the lateral positioning shaft servo drive positioning, strip inspection correction and longitudinal feeding positioning, stamping quality followup inspection, punching machine。 (3) workpiece surface appearance only with pressure liquid contact, pressure is gentle, parts forming process changes, can obtain the symmetry of uniform pressure distribution, and can winner much better smooth outside surface, (4) in stamping and bloom some hydraulic tool charge can reduce 40%, special reduced convex parts processing of takt time is shorter, about MIN, this in special forming process is shorter, may realize the batch production. Using the electromagic force generated electricity coil electromagic forming process, is the present quite promising another new processing method. This process from 1960s nuclear fission research achievement, but unfortunately has not been people attention. Electromagic forming technology principle diagram, when the coil access to electricity. Few microseconds inside establish electromagic field, so the metal workpieces especially conductivity strong copper aluminum texture produce electric current, a current, induced current induced by magic force and effect, make the workpiece create tension and anastomosis and rapid forming. When the coil in the workpiece in electromagic force will make workpiece outside of the current application, zhang forming widespread a kind of technology, When the coil planar parallel to the board piece is placed, electromagic force will make workpiece stretch forming. Electromagic forming technology is a noncontact forming process, and its outstanding merits are shaping a rapid high efficiency, 2 it is often used in metal or nonmetal connection, can replace adhesive or welding, A third is not consumption lymphocy help materials such as lubricating grease, etc, the advantageous environment protection. Stamping process automatic monitoring Modern scramjet another important feature is for punching process automatic monitoring to protect the stamping quality. In the mm stamping project automatic detection and monitoring, its research results will include: 1. The stamping process characteristics of online preach diagnosis and detection system, 2. High speed and noncontact measuring system。 4. Stamping key parameters online adjust and pensation system, etc. Stamping process changes caused by workpiece quality is mainly caused by the wear of convex punching die, crack,
