(3) utility model content
The purpose of this utility model is at above-mentioned existing problems, provides that a kind of technology is simple, reliable in quality, wall thickness is even and flexible extrusion forming device wrinkle resistant, the distortionless pipe bending part of cross section.
The technical solution of the utility model:
A kind of flexible extrusion forming device of pipe bending part comprises mould molding part, mould fixing part and pressures partially; Mould molding partly comprises die, punch and plug, and the discharge end of die has tapering, and punch is made of punch A and punch B for dividing body structure; Mould fixing part comprises lower bolster, retainer plate and cope match-plate pattern, retainer plate is fixed between lower bolster and cope match-plate pattern and by pin and screw and cope match-plate pattern, the center of lower bolster is provided with discharging opening, mould molding partly is arranged in the retainer plate, and the plug upper end is fixed in the groove of cope match-plate pattern by crossbeam; Pressures partially comprises location-plate, four fixed bars, two groups of hydraulic cylinders and piston A and piston B, two groups of hydraulic cylinders pass cope match-plate pattern and location-plate is fixed, location-plate is fixed by four fixed bars and retainer plate and lower bolster, piston A and piston B exert pressure to punch A and punch B respectively and have pressure reduction, and piston A and piston B move up and down in two groups of hydraulic cylinders respectively.
The technological parameter of described metal stock extrusion modling is that blank temperature room temperature～400 ℃, hydraulic pressure are 10t.
The tapering of described die discharge end is 45 °～60 °.
The scope of described pressure reduction is 1: 2～1: 3.
Operation principle of the present utility model:
The utility model by the flexible extrusion forming device with the metal stock extrusion modling, the piston of two hydraulic presses is exerted pressure respectively and is acted on two punch and have pressure reduction, when causing blank under the effect of punch, to move down, imbalance of flow at die conical outlet place metal, institute and then obtains our needed bending pipe fitting so that tubing occurs bending and deformation.The translational speed difference control metal flow that produces by pressure reduction can the differently curved angle of moulding, difform pipe bending part.
The utility model has the advantages that: in the extrusion forming device of pipe bending part, the punch of mould molding part adopts the split structural design, push the preparation pipe bending part by control pressure reduction, this apparatus structure is reasonable, process is simple, the pipe bending part wall thickness is even and wrinkle resistant, cross section is undistorted, reliable in quality is with a wide range of applications.
