In figure, 1 is spinning mold, and 2 is lathe attaching parts, and 3 install component for cylindrical shape blank, and 4 is spinning roller device, and 5 is spinning roller, and 6 is rotating mechanism, and 7 is fluted disc device, and 8 is finger, and 9 is fluted disc body, and 10 is cylindrical shape spinning part.
The specific embodiment:
Below in conjunction with specific embodiment, the present invention will be further described.
The invention process example: the blank internal diameter size 1500～2500mm of titanium alloy cylindrical shape spinning part 10, blank wall thickness dimension 45mm, effective length 700mm.
As shown in accompanying drawing 1-4, the titanium alloy cylindrical shape spinning part 10 heating is installed on to spinning mold 1, and makes cylindrical shape spinning part 10 and fluted disc device 7 laminatings.
Spinning mold 1 is directly connected with spinning lathe main shaft, and spinning mold 1 is done gyration in rotary pressing processing, is the main motion in rotary pressing processing, and spinning roller device 4 is connected with the slide of spinning lathe, does feed motion in rotary pressing processing.During spinning, the main shaft of spinning lathe rotarily drives spinning mold 1 rotation, and spinning mold 1 drives fluted disc device 7 and 10 rotations of cylindrical shape spinning part.
Spinning roller device 4 is by spinning lathe band action feed motion, when spinning roller 5 contact cylindrical shape spinning part 10, just can under the effect of frictional force, be driven and do gyration, now axially spinning force can make cylindrical shape spinning part 10 and fluted disc device 7 fit tightly, and in spinning, there will not be and relatively rotates.Gap between spinning roller 5 and spinning mold 1 is less than the wall thickness of cylindrical shape spinning part 10, cylindrical shape spinning part 10 can be subject to the extruding of spinning roller 5 and spinning mold 1 and pointwise distortion occurs, material deformation region is subject to the effect of three-dimensional compressive stress, deformation process is stable, due to titanium alloy cylindrical shape spinning part 10 deformation processes, be subject to the restriction of spinning mold 1 simultaneously, distortion mainly occurs in axially and radially, this just causes the attenuate of titanium alloy cylindrical shape spinning part 10 wall thickness and the increase of length, the final wall thickness of titanium alloy cylindrical shape spinning part 10 can be adjusted by the gap of adjusting between spinning roller 5 and spinning mold 1, to reach cylindrical shape spinning part 10 needed final sizes.
Complete after spinning, the titanium alloy cylindrical shape spinning part 10 that need to complete spinning is dismantled, and unloading process as shown in Figure 5.Until spinning mold 1 and titanium alloy cylindrical shape spinning part 10, be cooled to after normal temperature, to there is certain interval with titanium alloy cylindrical shape spinning part 10 in spinning mold 1, by the removal that is connected between fluted disc device 7 and spinning mold 1, with the reverse side of spinning roller 5, drive fluted disc device 7 titanium alloy cylindrical shape spinning part 10 can be unloaded.
Main processes of the present invention comprises the following steps:
Step 1: the blank of preparation cylindrical shape spinning part 10: the blank of turning processing cylindrical shape spinning part 10, reach spinning requirement, the blank internal diameter of cylindrical shape spinning part 10 requires than the large 2mm of spinning mold 1 diameter.
Step 2: spinning mold 1 is heated to more than 300 ℃, and adopt heating furnace the blank of cylindrical shape spinning part 10 to be heated to 2 times of left and right of the temperature of spinning mold 1, insulation is more than 2 hours, now the internal diameter size of the blank of cylindrical shape spinning part 10 will be slightly larger than the outside dimension of spinning mold 1, can complete spinning press setter and do.
Step 3: the blank that cylindrical shape spinning part 10 is installed, at the hot lower blank by cylindrical shape spinning part 10, be installed on spinning mold 1, now the internal diameter size of the blank of cylindrical shape spinning part 10 is slightly larger than the outside dimension of spinning mold 1, must complete fast the dress mold process of the blank of cylindrical shape spinning part 10, otherwise because part cooling, diameter shrink, cannot complete dress mould.
Step 4: rotary pressing processing, adopt spinning lathe to carry out rotary pressing processing to the blank of cylindrical shape spinning part 10, in spinning process due to the continuous heat radiation of the blank of spinning mold 1, cylindrical shape spinning part 10, spinning temperature can be more and more lower, so it is large that each passage reduction of rotary pressing processing is wanted, generally all more than 20%, total reduction is more than 70%, after can guaranteeing to machine, the grain size of titanium alloy cylindrical shape spinning part 10 improves more than 4 grades.
Step 5: dismounting titanium alloy cylindrical shape spinning part 10, until spinning mold 1 and titanium alloy cylindrical shape spinning part 10, be cooled to after normal temperature, because spinning mold 1 diameter amount of contraction is large, titanium alloy cylindrical shape spinning part 10 amounts of contraction are little, so have certain interval between spinning mold 1 and titanium alloy cylindrical shape spinning part 10, now tubular spinning part 10 can be dismantled smoothly.
