During produce axis hole process residue also can secondary utilize, thus reaching the purpose increased economic efficiency.
Referring to Fig. 2, in figure shows stator punching external diameter 18 1 timing, by changing axis hole punch 5 and axis hole die 16, can
Go out different rotor shaft hatch 19,20,21.
Original technological process：The silicon steel plate raw material of entire volume is cut into the side of product needed by numerically controlling vertical-horizontal shearing machine
Square stock is washed into only cylindrical and interfix hole two-spot circle material with former two-spot blanking die on large pressing machine and exists by material
On gap-framepress, two-spot circle material being gone out drives keyway that the two-spot circle material with driving keyway is placed on interior positioning at a high speed
On punch press positioning disk, go out stator grooved and concurrently separate out rotor by the rotation and indexing stator single-groove punch-die of equipment
The rotor separated circle material technology hole is expanded on gap-framepress by circle material with process drive keyway reaming mould
True axis hole, on interior positioning high velocity ram machine, the rotor circle material with true axis hole is placed on the positioning disk of equipment, by setting
Standby rotation and indexing rotor single-groove punch-die go out slot shape of rotor.
Referring to Fig. 3, location hole 23 shown in figure, find out from the rotor shaft hatch material schematic diagram that former technique drops out, external diameter is big
Little can just be used in the rotor punching of H160 motor, but, due to there being the driving keyway of wide 25 deep 5 on cylindrical
22, lead to not continue in the rotor punching of H160 motor with this axis hole waste material, have to high use the in Jiang Yige center be
H132, its external diameter is Φ 210, and after calculating, utilization rate is 62.8%.
Referring to Fig. 4, the keyway of head dummy convex shown in figure 24, from the rotor shaft hatch schematic diagram that present invention process drops out
Go out, due to not having wide 25 deep 5 driving keyway, so being just used in the rotor punching of H160 motor, its external diameter is Φ
260, after calculating, utilization rate is 96.26 %.
Found by the comparison of above-mentioned utilization rate, two kinds of process variations are very big, similar situation is a lot, so the present invention
Two-spot process economicses effect is very prominent.
