STAMP FOR RESEARCH open die forging of forgings

摘要

Stamp for research open die forging of forgings relates to metal forming, in particular for the investigation of open die forging round in plan forgings with inner and outer burr shifted to one or opposite ends of the forging, comprising an upper and a lower die half with engravings forming a groove with a variable section, store and obloyny bridge, and can be applied in all branches of engineering.; Annular preform is heated and produce stamping and trimming the inner and outer fin shifted to one or opposite ends of the forging.; Obloyny die bridge formed by conjugation of the horizontal portion, directly adjacent to the die stream, the length of which is 0.1-0.3 obloynogo bridge width, with a portion beyond the end face of the forging, the protrusion formed on one half of the die, a limited part of the circumference (arc) of radius R ₁ and groove on the other half die radius R _2.; Grooves on one half of the die radius R ₂ is eccentrically offset relative to the projections on the other half die of radius R ₁ at the value h, where h - height of the burr on the calculated obloynom bridge, and form at the die perimeter expanding stream obloyny bridge smoothly passes into a tapering obloyny bridge.; Said die for forging of forgings research and provides a correct choice obloynogo bridge design in different sections along the perimeter of the projected stream stamp. The positive effect is to reduce the effort stamping decrease warpage forging, stamping burr deviations and thickness.; 1 n. Formula 1 yl.
