Description
Technical field
The utility model relates to a kind of motor stator full circle punching jet-bedding dividing die.
Background technology
Motor has stator punching and rotor punching, for the stator punching of diameter less than 1.25m, is typically designed to circular piece, and the rotor punching jacking is in stator punching inside, and shape is similarly circular piece.
During the punching punching out, traditional technological process is: stator cylindrical blanking, and---------red switch pilot trench shape---rotor punching separates towards stator slot shape towards keyway.Need the mould of design to have: stator punching cylindrical blanking die, rotor flute profile and keyway list groove dash, rotor punching splitting die (band doff hole).Use this flushing technology, rotor separates needs design specialized peel of mould, manufacturing cost height.
The utility model content
The utility model is exactly in order to address the above problem, reduce die manufacturing cost, a kind of motor stator full circle punching jet-bedding dividing die is provided, it can reduce die manufacturing cost, in the punching out stator slot shape, can come stator inner hole cutting simultaneously, like this, stator punching has just been made finished product after the punching out flute profile.Simultaneously no matter how little air gap is between the rotor can both realize this function, has prevented the phenomenon that drift that mould causes because of air gap is little bursts apart.
For achieving the above object, the utility model adopts following technical scheme:
A kind of motor full circle stator punching jet-bedding dividing die, it divides upper die and lower die, and described patrix is connected with punch press, also is provided with positioner between the two; The upper mould fixed plate of patrix is provided with and corresponding flute profile drift of counterdie and cutting drift; Described counterdie comprises counterdie sword piece, and counterdie sword piece is provided with and flute profile drift and corresponding respectively counterdie flute profile mould sword and the counterdie dividing die sword of cutting drift, and counterdie sword piece is installed on the die shoe; Upper and lower intermode also is provided with guide position limiter.
Described guide locating device provided strong for a pair of location that is installed in the patrix top, patrix is connected with punch press by the patrix die shank.
Described guide position limiter comprises a pair of guide pillar that is installed in upper mould fixed plate, then is provided with a pair of guide pin bushing that matches with guide pillar on die shoe.
Described upper mould fixed plate bottom is provided with stripper plate, is provided with resilient rubbber cushion between the two.
Described counterdie dividing die sword is a gap formula groove.
Described counterdie sword piece top one side is the inclined-plane.
Described flute profile nose of punch is designed to the circular arc cutter.
The utility model is in locate mode: patrix is installed on the high velocity ram machine, and patrix die shank and punch press are depended merely on centre bore and can not be located fully, and die shank can rotate in centre bore.The utility model has utilized two positioning keys, and it is installed on the die shank, and like this, patrix just can be realized location fully with lathe.
Punching groove shapedly realize to separate simultaneously: single drift can only the punching out stator slot shape, and this utility model is separated design with flute profile and separate punches, has realized the cutting function of all punchings.
The design of counterdie sword block structure: counterdie sword piece is when shearing, and punching is out of shape.The cutting cutting edge of counterdie sword piece is designed to gap formula groove, can prevents that punching from tearing; Side with counterdie sword piece is designed to ramp structure simultaneously, and after reason was cutting, the downward joining seam in punching position of shearing, ramp structure had reduced punching when rotating and the resistance of counterdie sword piece, and punching gets into smooth more steady.
Upper and lower mould edge material is Cr12, adopts the line cutting processing.After the processing, guarantee that upper and lower mould sword gap is at 0.03mm-0.07mm.
Configuration guide pillar guide pin bushing structure, when the punching punching out, upper and lower mould relative position remains unchanged.
The beneficial effects of the utility model are: omitted rotor punching separation circuit, reduced punching out Mould design and manufacturing.Shorten the manufacturing cycle, effectively improved the technological level of company and the competitiveness in the same industry of market.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Among Fig. 1, it divides upper die and lower die, and described patrix is connected with punch press, also is provided with positioner between the two; The upper mould fixed plate 2 of patrix is provided with and corresponding flute profile drift 3 of counterdie and cutting drift 11; Described counterdie comprises counterdie sword piece 6, counterdie sword piece 6 is installed on the die shoe, on counterdie sword piece 6, be provided with the counterdie flute profile mould sword 13 and the counterdie dividing die sword 14 that match with flute profile drift 3 and cutting drift 11, shown in Fig. 2 a, Fig. 2 b, Fig. 2 c, Fig. 2 d and Fig. 3 a, Fig. 3 b.
7 of the die shoes of upper mould fixed plate 2 and counterdie also are provided with guide position limiter.
