Specific embodiment
Arrangement form of the invention is further described with reference to the accompanying drawing, but claimed range is not limited to institute It states.
As shown in Figure 1, being 5 structure chart of shield to be processed, Fig. 2 is to add for metal thin-wall shield reinforcing rib spinning Work special tooling, the tooling include consisting of part:
Such as Fig. 2 and Fig. 8, each component part is as follows:
Spinning block 1: quantity 1 (including 3 mold sections), effect include three aspects, 1. the clamping of shield 5, in spinning block 1 Pore sizeIt is consistent with 5 outer diameter of part shield, and it is cut into uniform 3 valve with spinning block 1, stay about 0.5mm to fill between every valve With gap, it is convenient for Workpiece clamping;2. on the basis of positioning reinforcing rib size, with an end face of spinning block 1, according to part reinforcing rib ruler Very little requirement determines size A1, A2, A3 ...;3. reinforcing rib rotary press modelling controls the shape of reinforcing rib by being spun into type groove And size, such as Fig. 3 and Fig. 4.
Clip 2: quantity 2, effect includes two aspects: 1. concordant spinning block 1, passes through the interior step surface (annular on clip 2 Protrusion), it is aligned convenient for 3 valve spinning blocks 1 when assembly, guarantee is spun into type groove alignment;2. fixed spinning block 1, by tightening nut 23, so that clip 2 is clamped spinning block 1, as shown in Fig. 5 and Fig. 2.
