Abstract
The utility model discloses a single-trough machine mold capable of simultaneously punching a slot, an excircle and an axle hole inner circle of a motor rotor. A punch comprises a rotor slot-shaped punch body cutting the excircle and a punch body cutting the axle hole inner circle, and is fixed on an upper fixing plate, and the position and the size of the punch correspond to those of the slot, the excircle and the axle hole inner circle of a rotor punching needed to be punched; and cutting edges corresponding to the rotor slot-shaped punch body cutting the excircle and the punch body cutting the axle hole inner circle are arranged on a lower mold. Since the rotor slot-shaped punch body cutting the excircle and the punch body cutting the axle hole inner circle are designed onto the same mold to simultaneously complete the work of punching the rotor slot, as well as cutting the rotor excircle and the axle hole inner circle, a conventional blanking mold can be used to economically and quickly obtain a full-circle rotor punch piece. The mold is convenient to modify, has high punching efficiency, can guarantee periods for product research and development, single special motor design and production, and motor repair, and the obtained rotor punch piece can completely meet design requirements.

For achieving the above object, the technical scheme taked of the utility model is:
A kind of single scouring machine mould of circle in rotor flute profile, cylindrical and the axis hole simultaneously, form by part of the upper die and part of the lower die, the part of the upper die is made up of upper bolster, upper mounted plate, drift, rubber and stripper, stripper, rubber and upper mounted plate adopt removably to link together, rubber precompressed between stripper and upper mounted plate, the end face of drift flushes with the end face of upper mounted plate, and drift passes rubber and enters stripper, and upper mounted plate adopts removably to be connected with upper bolster; The part of the lower die is made up of counterdie, compact heap and die shoe, compact heap is with the counterdie jam-packed and be fixed on the die shoe, it is characterized in that: described drift comprises that rotor slot shape is double and cuts outer round punch and cut round punch in the axis hole, described drift is installed on the upper mounted plate, and the position and the size of justifying in flute profile, cylindrical and the axis hole of the position that drift is laid, size and the rotor punching of required punching out are corresponding; Counterdie is provided with rotor slot shape is double and cuts outer round punch and cut the corresponding cutting edge of round punch in the axis hole.
Described stripper, rubber and upper mounted plate are connected by the discharging screw, and upper mounted plate is connected by screw with upper bolster, and counterdie is connected with die shoe with screw by compact heap, and wherein upper bolster, die shoe and compact heap are general.
Described rotor slot shape is double to be cut outer round punch and cuts that round punch adopts interference fit in the axis hole, expanded metal is fixed or bonding mode is installed on the upper mounted plate.
What the utility model provided is above-mentioned simultaneously towards the rotor flute profile; single scouring machine mould of circle in cylindrical and the axis hole; owing to cut outer round punch with rotor slot shape is double; cut the interior round punch design of axis hole on a mold; finish red switch pilot trench shape simultaneously; cut the rotor cylindrical and cut sired results work in the rotor; realize using of existing blanking die; can be economical; obtain the round rotor punching quickly; the material and the processing charges of compound moulds such as special-purpose blanking die or splitting die or multiple red switch pilot trench mould have been saved; saved replacing; the time of debugging mould; reduce labour intensity, reduced the punching waste that die trial causes.The circle size partly or entirely after changing in rotor slot shape size, rotor quantity and excircle dimension and axis hole, the mould that the utility model provides is when remodeling, only need that flute profile in the mold exchange more is double cuts outer round punch and cut the interior round punch of axis hole, upper mounted plate, stripper and counterdie, all the other mould parts are general, realize remodeling fast, guarantee that research and development product, the design of separate unit special machines are produced and the cycle of motor repair, and resulting round rotor punching can meet design requirement fully.
