The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
Suppress the boiler smoke-box tube sheet of band eccentric orfice as shown in Figure 1, the utility model adopts composite die as shown in Figure 2, comprises shaping patrix 1, forming lower die 2, stripper ring 3, flange die 4 and drift 5.Shaping patrix 1 is a cylinder, and the cylindrical hole of an off-centre is arranged in it, and this cylindrical axis is parallel with the axis in eccentric cylinder hole, and the outer wall of moulding patrix 1 lower end is provided with circumferential boss 9.The upper end of drift 5 is that cylinder, lower end are circular cone, and the diameter of circular cone maximum is determined by the diameter in workpiece centre hole.
As shown in Figure 3, stripper ring 3 is a T shape cylinder, has formed the larger diameter end 3a and the smaller diameter end 3b of stripper ring 3, and a cylindrical hole coaxial with stripper ring 3 arranged in the stripper ring 3.
As shown in Figure 2, during installation, drift 5 is coaxial with the cylindrical hole in the moulding patrix 1, and shaping patrix 1 wraps in outside the drift 5; Stripper ring 3 is coaxial with shaping patrix 1, with stripper ring 3 kinks on shaping patrix 1; Stripper ring 3 falls by deadweight, and the circumferential boss 9 that shaping patrix 1 lower end outer wall is provided with can make stripper ring 3 stop to fall behind plane on the circumferential boss 9 that contacts shaping patrix 1; After going here and there drift 5, moulding patrix 1 and stripper ring 3 well, again drift 5 is installed on the forcing press.
Moulding counterdie 2 links to each other with fixed bearing 7 under being positioned at it, is arranged with 3-4 fixed bearing 7 that becomes circle distribution at forming lower die 2, forming lower die 2 transfixion all the time when the hot pressing workpiece.One cylindrical hole is arranged in the moulding counterdie 2, and the diameter of this cylindrical hole is less than the major diameter of stripper ring 3, greater than the minor diameter of stripper ring 3.During installation, this cylindrical hole is coaxial with described stripper ring 3, and when guaranteeing that stripper ring 3 falls, its larger diameter end 3a drops on forming lower die 2 upper surfaces, and its smaller diameter end 3b inserts in the gap between described forming lower die 2 and the shaping patrix 1.
Flange die 4 is positioned at described shaping patrix 1 time, and its upper end is stretched in the moulding counterdie 2, and this flange die 4 links to each other with pneumatic supporting 8 be positioned at it under, is arranged with the pneumatic supporting 8 of 3-4 one-tenth circle distribution at flange die 4.
After installing composite die, the plate workpiece 6 that has centre bore of heating is shelved on the forming lower die 2, shaping patrix 1 and drift 5 press down under the effect of forcing press simultaneously, stripper ring 3 falls with shaping patrix 1 by deadweight, drift 5 is contact workpiece 6 at first, workpiece 6 is out of shape under the pressure effect of drift 5 and shaping patrix 1, drift 5 lower end circular cones pass the centre bore of workpiece 6, stop to fall behind the plane on the stripper ring 3 contact forming lower dies 2, shaping patrix 1 and drift 5 continue to press down, when be depressed into flange die 4 on the spacing on plane during just for the thickness of workpiece 6, flange die 4 stops shaping patrixes 1 to continue to press down; Pull limit 11 equal diameters in the cylindrical hole diameter of forming lower die 2 and the workpiece 6, the cylindrical hole diameter of flange die 4 and workpiece 6 outer limit 12 equal diameters of pulling are shaped pulling the limit in the workpiece 6 and pulling the limit outward simultaneously by forming lower die 2 and flange die 4; After the shaping, workpiece 6 and shaping patrix 1 are bonded together, and unload the drift 5 that adds on the press, and pneumatic supporting 8 overthrows upwards that edge die 4 drives workpiece 6 and moulding patrix 1 is up, and drift 5 keeps motionless.Pull limit 11 in the workpiece 6 and tilt to axis because of being heated, the plane at first contacts the lower limb of stripper ring 3 on the workpiece 6, and the gravity of stripper ring 3 is equivalent to workpiece 6 has been applied resistance, makes workpiece 6 automatic and shaping patrix 1 disengagements, has realized automatic demoulding.
For implementing this utility model better, low inside and high outside tapered plane is arranged on the last plane of shaping patrix 1 circumferential boss 9, the relatively thin easier processing in straight plane, can not fracture because of root is too thin, can avoid equally the side of circumferential boss 9 and workpiece 6 in pull limit 11 straightway fit and cause the demoulding to have certain difficulty, correspondingly, the lower plane of stripper ring 3 is arranged to and the circumferential consistent tapered plane of last plane gradient of boss 9.
For further implementing this utility model better, moulding patrix 1 and drift 5 are provided with radial hole 10, and available holding pin couples together shaping patrix 1 and drift 5.Moulding patrix 1 is inconsistent because of the off-centre wall thickness, for alleviating the weight of shaping patrix 1, at the heavy wall place cavity 13 can be set.
