The cold-hot stamping die comprises a base, a die cavity formed by stacking a plurality of clamping rings and used for placing the pole coil, a stamping die and an insulated supporting plate mounted in the die cavity, and a pressure cap mounted at the upper end of the die cavity, and is characterized in that the stamping die comprises a middle die core, a pole coil width adjusting plate, four separated end mould cores, and middle expanding blocks, wherein, the middle die core is provided with a certain drafting angle; the pole coil width adjusting plate is mounted on one side of the middle die core through a countersunk head screw; the separated end mould cores are symmetrically mounted at two ends of the middle die core; a middle expanding block is mounted between two end mould cores on the same side edge; and the pole coil width adjusting plate with a drafting angle which is the same as that of the middle die core is mounted on the side surfaces of the middle expanding blocks. The utility model meets the insulated requirements for producing the electrode body of the pole coil through hot pressing, saves a set of mould core tooling design and manufacture cost, reduces the production cost of a motor, shortens die manufacture period, and facilitates civilized die management; moreover, the utility model further has the advantages of simple structure, easy processing, and the like, saves raw material, and reduces die low manufacturing.
Description
Technical field
The utility model belongs to pole coil manufacturing technology field, particularly relates to the cold and hot pressing mold of a kind of pole coils of tubular turbines.
Background technology
At present, the pole coils of tubular turbines that my company produces adopts domestic and international advanced design technology, internal diameter design to adopt the pole(cell) insulation structure, hot pressing finish later pole coil directly with the pole core suit, saved the boiling hot operation of praising of pole core.During the cold and hot pressing mold frock design of pole coil, consider the monolateral insulation thickness of pole(cell) insulation, need rise in the middle of design two covers piece and middle core rod, a cover is used for the cold, hot pressure moulding, another set ofly is used to suppress pole(cell) insulation; After treating that promptly the cold, hot pressure turn-to-turn finishes, change the second cover pressing mold and carry out the hot pressing pole(cell) insulation, this kind mode has deficiencies such as complicated operation, labour intensity are big, inefficiency; Bring the difficulty of producing extensively very much to Mould Machining in addition, increased the Mould Machining cost of manufacture, raw material are caused waste, be unfavorable for the mould management of carrying out production strictly in line with rules and regulations simultaneously.
Summary of the invention
The utility model provides a kind of cold and hot pressing mold of pole coils of tubular turbines of processing, save raw material, reducing cost of manufacture and increase work efficiency of being easy to for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
The cold and hot pressing mold of a kind of pole coils of tubular turbines, comprise base, be formed by stacking the die cavity of placing pole coil by several trim rings, pressing mold of in die cavity, installing and insulation supporting plate and the pressure cap that is installed in the die cavity upper end, it is characterized in that: described pressing mold comprises the middle core rod that has certain drafting angle, by sunk screw the pole coil width adjustment plates is installed in a side of middle core rod; Four split end core rods at core rod two ends during symmetry is installed in; The centre of installing between two of the same side end core rods piece that rises is equipped with the pole coil length adjustment plate identical with middle core rod drafting angle by sunk screw on rising by the side of piece in the centre.
The utility model can also adopt following technical measures:
Leave the gap of 8mm～15mm in described between the both ends of core rod and the end core rod.
Hold the gap of leaving 5mm～15mm between the core rod for two of core rod one end in described.
The thickness of described width adjustment plates is 1mm～4mm.
The thickness of described length adjustment plate is 1mm～4mm.
Advantage and the good effect that the utlity model has are: because the utility model adopts the piece side of rising in middle core rod and centre to add dismountable width adjustment plates and length adjustment plate, to have solved the production of hot pressing pole coil pole(cell) insulation need, saved cover a core rod frock design and a manufacturing cost, reduced motor manufacturing cost, shortened the Mold Making cycle, satisfied pole coil and produced needs, more help the civilization management of mould; In addition the utility model also have simple in structure, be easy to processing, save material and reduce the Mold Making low cost and other advantages.
