The positive and negative continuous compacting brake forming principle that the present invention adopts is that the sheet metal material is placed on the counterdie, when patrix presses down, at first makes the sheet metal material be subjected to the effect of vertical force, and steel plate is pressed into
Shape promptly is subjected to the result of positive pressure.Like this, the sheet metal material is in bending deformation area generation plastic history, and skin bears stretching, and the internal layer pressurized causes cross section generation deformation, and the stretching that is produced, compression stress make and leave part stress in the material.At this moment, at material
The center in zone forces to apply buffer brake, makes
The zone with
Form develop to plastic deformation, the compacting
Stress and compacting that the zone produces
Power offset.Along with proceeding of pressing process, finally make the equidistant many node compression moulding of circular arc.
