PROBLEM TO BE SOLVED: To provide aluminum balls as a material for an aluminum shoe of high dimensional accuracy. SOLUTION: A cut piece 172 is obtained by shear-cutting an aluminum alloy round bar 170 in a cutting step S1. Next, in an aluminum shoe stock forming step (an aluminum ball forming step) S2, an intermediate shape stock 187 is obtained by forming the cut piece 172 by a semi-sealed die forging. The intermediate shape stock 187 has a spherical shape of substantially same shape and dimension as an aluminum shoe stock 160 being an aluminum ball, and excess material is formed as burrs 190 on an outer circumferential surface thereof. The burrs 190 are removed in a deburring step S3 to obtain a substantially- shaped stock 229, and by improving the surface roughness and the dimensional accuracy via a grinding step S4, the aluminum shoe stock 160 of high dimensional accuracy is obtained. The shearing and the die forging can be performed rapidly, and the productivity of manufacturing aluminum balls is improved. The aluminum shoe stock 160 of excellent dimensional accuracy is obtained, and thus, the dimensional accuracy of a shoe manufactured out of the stock 160 is also improved. | ||||||

[Problem to be solved] To provide a novel method for efficiently manufacturing a press product that includes, in an integrated manner, a flat part (a vane part) and a rod part (a shaft part) having a diameter greater than the thickness of the flat part. [Solution] The present invention includes steps of: preparing a preformed material in which a blank material is prepared as a preformed material for a press product (a variable vane); forging a rod part in which the preformed material is formed into a desired shape by interposing the preformed material between a pair of opposed dies and pressing mainly the rod part from a direction orthogonal to a punching direction; and trimming a rod part in which an unnecessary portion resulted from the forging processing is trimmed. The preformed material remains in contact with a part of a strip material to be passed along in the progressive processing. The step of forging a rod part is performed upon turning over the preformed material in a punching orientation by 90° with respect to the strip material and changing the orientation of a flat part into a vertical direction, the preformed material having been blanked in the step of preparing a preformed material. The subsequent step of trimming a rod part is also performed while the flat part is oriented in the vertical direction. |
