Description

Fluid torque-converter fin piercing and flanging mould

Technical field

The present invention relates to a kind of mould, particularly relate to a kind of fluid torque-converter fin piercing and flanging mould.

Background technology

Its structure of fluid torque-converter fin is circular thin slice, and on it, rounded array distribution has a plurality of slotted holes, and one side of slotted hole is with flange flange.Now, the processing technology of fluid torque-converter fin is mainly first to go out annulus thin slice, bores fabrication hole on drilling machine, and then with fabrication hole location, and piercing and flanging one by one on punch press, has how many flange just must rush how many times.Therefore, adopt above-mentioned technology to carry out the punching of fluid torque-converter fin, flange, have following defect: one, operation is many, labour intensity is large, and efficiency is low; Two, mould is frequently used, fragile, and production cost is higher; Three, location difficulty, machining accuracy is wayward, and quality stability is poor.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of fluid torque-converter fin piercing and flanging mould, adopt this mould, can realize one-time positioning, the moulding of one-off hole-piercing flange, the steady quality of fluid torque-converter fin, production efficiency are improved, and extend the service life of this mould.

For solving the problems of the technologies described above, the invention provides a kind of fluid torque-converter fin piercing and flanging mould, it comprises punch and die, and described punch comprises punch upper bolster, punch edge of a knife piece, plastic eraser pad, punch die mould piece, alignment pin, the bolt connecting successively from top to bottom and hangs nail; Described die comprises die die shoe, die spring underlay, spring, die edge of a knife pad, die die mould piece, die edge of a knife piece, bolt and the pin connecting successively from bottom to top;

In described punch, punch edge of a knife piece is placed in punch upper bolster center, and both are bolted fixing; On punch edge of a knife piece, rounded array distribution has several edges of a knife consistent with punching shape, on the edge of a knife, is fillet with the blade of piercing and flanging respective side; Hang nail and be fixedly connected with punch die mould piece through punch upper bolster, punch edge of a knife piece, between punch edge of a knife piece and punch die mould piece, be provided with plastic eraser pad, on punch die mould piece, offer the perforation hole slot corresponding with the edge of a knife;

In described die, die spring underlay is placed in die die shoe center, and both are bolted fixing; Die die mould piece is placed on die spring underlay, both are connected and fixed by alignment pin, on die die mould piece, rounded array distribution has several perforation hole slots consistent with punching shape, and hole slot is corresponding with punch edge of a knife position, and the material that the width that the width of its hole slot is the edge of a knife adds flange is thick; Die spring underlay middle part is provided with cavity, built-in several springs, and spring upper end undertakes die edge of a knife pad; Hole slot on die die mould piece is built-in with die edge of a knife piece, and its upper end is consistent with die die mould piece surface of internal cavity, and bottom is placed on die edge of a knife pad;

Described punch is connected with die, by the guide pillar arranging on the guide pin bushing arranging on punch upper bolster and die die shoe, is worked in coordination, and between punch die mould piece and die die mould piece, by alignment pin, is led and is coordinated.

For can concise description for the purpose of problem, below to fluid torque-converter fin piercing and flanging mould of the present invention all referred to as this mould.

The operation principle of this mould is:

This mould is contained on punch press, presses punch press switch, when punch is pressed onto on the fin plate in die, punch die mould piece and die die mould piece compress fin plate, now under certain pressure-acting, by the nail that hangs being free to slide, connect, plastic eraser pad in punch can produce compression, so will stretching out punch die mould piece, continues to pressing down a stroke (this stroke is the decrement that plastic eraser pad produces) punch edge of a knife piece (inclined-plane), now the blade of the punch edge of a knife piece end edge of a knife cuts off one side of fin plate, continue to press down, the part that the fillet of punch edge of a knife piece props up fin will become flange, be stuck between the side and punch edge of a knife piece inclined-plane of slotted eye of die die mould piece (because other one side of the punch edge of a knife piece edge of a knife is fillet, there is no blade, so can not cut off flange), die edge of a knife piece in die die mould piece in slotted eye, under the punching press of punch edge of a knife piece, by pressing down die edge of a knife pad, makes the spring-compressed in die spring underlay middle part, until the flange after fin punching forms, unclamp punch press switch, pressure disappears, plastic eraser pad in punch resiles, punch edge of a knife piece is returned in punch die mould piece, spring in die also will recover reset condition, by die edge of a knife pad, by die edge of a knife piece jack-up, die edge of a knife piece can eject made fin, has so just completed punching, the flange forming process of a fin.

In sum, adopt this mould, avoided punching one by one continually, simplified manufacturing procedure, labour intensity and production cost have been reduced, can realize one-time positioning, the moulding of one-off hole-piercing flange, the steady quality of fluid torque-converter fin, production efficiency are improved, and extend the service life of this mould.

Separately, this mould structure is simple, safe and reliable.
