In the hydro piercing process, pierce punch 4 links to each other with punching hydraulic cylinder 5, relies on the hydraulic cylinder motion to drive drift and advances, retreats, thereby realize punching.At present, being connected mainly between drift and the punching hydraulic cylinder realizes by a plurality of contiguous blocks and transition block, and realizes the stable position of drift by the installation of transition block.
But, in the actual installation of drift and use, be prone to following several anomaly:
One, drift can not accurately be located, and the drift position is unfixing in the forming process.Mainly show as: (1) nose of punch is higher than mold cavity, cause punching begin preceding, in hydroforming process, tubing just ftractures.(2) nose of punch is lower than mold cavity, cause punching to finish after, projection, uneven appears in the hole peripheral profiles.
Two, drift rotates in the punch process.Under a lot of situations of hydro piercing is piercing and flanging, material and not exclusively washing out, if drift rotates, then the material that gets off of flange will can not guarantee the repeatability of hole quality on all parts towards different directions, influences follow-up welding assembling.
Three, drift fractures too early.Because drift is subjected to from tubing and the very big reaction force of internal high pressure liquid thereof in the punch process, if the design of drift location is unreasonable, drift can decline to a great extent service life, even the phenomenon of drift fracture occurs.
