PROCEDURE AND DEVICE FOR THE MANUFACTURE OF A HOLLOW TREE WITH EXTERNAL RADIAL ELEVATIONS BY MEANS OF DEFORMATION WITH HIGH INTERNAL PRESSURE.

摘要

IN A PROCEDURE FOR MANUFACTURING PARTS BY THE PROCEDURE OF CONFORMING FOR HIGH INTERNAL PRESSURE FROM A SEMI-FINISHED PRODUCT FOR A HOLLOW AXIS MODE, WHICH PRESENTS EXTERNAL RADIAL ELEVATIONS OR EXTRICTIONS THAT PENETRATE TO THE INTERIOR OF THE AXIS, FOR EXTRICTION PREFORMED IN THE CONFORMING AREA OF THE SEMI-FINISHED PRODUCT ARE SUBJECTED TO AN AXIAL FORCE DURING THE CONFORMING AT HIGH PRESSURE, THE TOOL IS CLOSED. IN A DEVICE FOR THE MANUFACTURE OF A CAMSHAFT TREE ACCORDING TO THIS PROCEDURE, THE TOOL (11) IS COMPOSED OF A DIVIDED BLOCK (12, 14, 15), REPRODUCING INSIDE THE GROUP'S GEOMETRY (2, 3 OR 4 , 5 OR 6.7 U 8.9) OF THE ELEVATIONS (2 TO 9), WHERE TWO AXIAL BLOCKS (15, 16) OPPOSED BETWEEN, THE FIRST AXIAL BLOCK (16) FULLY ENCLOSES AN ELEVATION (7) WITH A REDUCTION (21) THAT CORRESPONDS WITH THE BASIC GEOMETRY OF THE ELEVATIONS (2 TO 9), AND ON THE OTHER HAND IS ATTACHED WITH ITS FRONT FACE (18) ORIENTED TO THE SECOND AXIAL BLOCK (15), FROM THE OUTSIDE AGAINST THE ELEVATION ( 8) NEXT, MAKING FORCE ON HER, WHILE THE SECOND AXIAL BLOCK (15) MAKES FORCE FROM THE OUTSIDE AGAINST THE ELEVATION (9) CONTIGATES THE NEXT ELEVATION (8), WHERE A CENTRAL BLOCK (12) SITUATED BETWEEN THE TWO AXIALS (15, 16), WHICH SUPPORTS THE AXIAL BLOCKS WITH SLIDING MOVEMENT (15, 16), CLOSES THE SEMI-FINISHED PRODUCT (1) BETWEEN THE TWO ELEVATIONS ( 8, 9) SUBJECT TO PRESSURE.
