Abstract
A kind of major axis class big inclination angle flange forge piece manufacturing process, it is the processing of inclination angle big to major axis class flange forge piece, forging material is titanium alloy or high temperature alloy, prepare fetal membrane and the instrument of forging forming, fetal membrane and instrument are preheated, is placed on the anvil face of forging hammer, first by the lower mold of finishing die, it is placed in overcoat inner chamber, then blank is taken out in the lower mold being placed on finishing die from heating furnace；The upper mold of flat-die hammer hammering finishing die, makes blank be gradually filled with impression between the upper and lower mould of finishing die, and pulling bar portion is to forging's block dimension.Advantages of the present invention: the Making mold used is simple, low cost, and the cycle is short, in being particularly suitable for, the production of small lot forging, the method is widely used in the base production of the forging such as aeronautical product rotor blade, nozzle body, and material relates to titanium alloy, high temperature alloy etc., and application prospect is extensive.
Description
Technical field
The present invention relates to plastic forming process field, specifically provide a kind of major axis class big inclination angle flange forge piece manufacturing process.
Background technology
Major axis class big inclination angle flange is a kind of typical structure of flange forge piece in aeronautical product, there is bar portion size long, inclination angle, flange position is big waits shaping characteristic, be typically employed on horizontal forging and upsetting machine repeatedly assemble, the Simulation Based On Multi-step such as heading, pressure angle shapes, requirement equipment tonnage is big, there is Making mold complicated, costly, the shortcomings such as process-cycle length, local deformation is carried out by die clamping bar additionally, due to horizontal forging and upsetting machine, typically use high-precision hot rolled rod, to avoid causing not clamping or producing longitudinal burr between die.
Summary of the invention
The invention aims to avoid original shape the high-precision requirement to bar on horizontal forging and upsetting machine, make forging shape closer to the profile of part, spy provides a kind of major axis class big inclination angle flange forge piece manufacturing process.
The invention provides a kind of major axis class big inclination angle flange forge piece manufacturing process, it is characterized in that: described major axis class big inclination angle flange forge piece manufacturing process is the processing of inclination angle big to major axis class flange forge piece, forging material is titanium alloy or high temperature alloy, prepare fetal membrane and the instrument of forging forming, fetal membrane and instrument are preheating to 200～300 DEG C, it is placed on the anvil face of forging hammer with manipulation machine clamping casing mould, first by the lower mold of finishing die, it is placed in overcoat inner chamber, would be heated to forming temperature again and be 950 DEG C or 1160 DEG C and the blank that is incubated 20～60 minutes takes out in the lower mold being placed on finishing die from heating furnace, aligned position, finally the upper mold of finishing die it is buckled in blank top and adjusts position；
The upper mold of 3 tons or 0.4 ton flat-die hammer hammering finishing dies, it is allowed to slowly fall along outer casing inner wall, blank is made to be gradually filled with impression between the upper and lower mould of finishing die, touch the upper mold of finishing die, the upper and lower mould of shaping is made to come off from overcoat, blank again melts down and carries out being heated to 950 DEG C or 1160 DEG C, and is incubated 20～30 minutes；
The blank that would be heated to forming temperature takes out from heating furnace, is placed on the flat anvil face of 3 tons or 0.4 ton flat-die hammers, supporting rod portion, and hammering flattening flange position is to requiring size, then clamps flange head, and pulling bar portion is to forging's block dimension.
The lower mold of described finishing die is Split type structure, and separately, outer set fastens left and right half module.
Described fetal membrane gabarit is oblate, prevents angle from offseting, it is ensured that during production, upper and lower mould aligns.
Advantages of the present invention:
The big inclination angle of major axis class of the present invention flange forge piece manufacturing process, the Making mold used is simple, low cost, cycle is short, in being particularly suitable for, the production of small lot forging, the method is widely used in the base production of the forging such as aeronautical product rotor blade, nozzle body, and material relates to titanium alloy, high temperature alloy etc., and application prospect is extensive.
