operation principle:
Former is not provided with the step-like annular shaping powder metallurgy products of step:
Shaping state: taking blame for others drives negative template to go upward to top dead centre by lower pulling plate, lower link, and the cylinder that floats drives float plate to go upward to top dead centre, makes lower outside floating punch, plug stretches in former; Cavity side cylinder is motionless, and the piston rod of float plate side cylinder all stretches out, and makes cushion block in float plate be positioned at above float plate lower cushion block;
Then top shoe drive upper outside punching and upper in sweep away row, in the descending process of top shoe, upper outside piston cylinder air inlet, make the upper outside punching that connects with upper outer piston relative upper in rush at down and stretch out, until be pressed in former by powder metallurgy product, in now going up, rush not contact product;
Top shoe continue descending, now, due to lower outside floating punch, lower internal fixtion punching spacing, upper outside punching cannot continue descending, its relative powder metallurgy product is relatively motionless, but upper outsidely rushes piston and upper outsidely rush gap between cylinder bottom and reduce gradually, and upper interior punching is stretched in product;
Top shoe continues descending, rush piston when upper outside and upper outsidely rush between cylinder bottom after gapless, upper outside punching and upper interior punching descending lower die pressing product simultaneously, meanwhile, float plate, floating punch also move down with certain speed under floating cylinder drives, and former also moves down under the effect of product frictional force thereupon, realize complete floating shaping, guarantee that product density reaches unanimity;
In the process, top shoe constantly descending, the piston rod of forced-floating cylinder is made to prop up forced-floating bar, between the piston rod of forced-floating cylinder and cylinder bottom, gap constantly reduces, to promote after gapless between the piston rod of cylinder and its cylinder bottom until float float plate and on floating punch move down, cushion block in the float plate of float plate is finally made to prop up float plate lower cushion block, and then it is spacing to the shaping lower dead center of float plate, again because the distance between top shoe and float plate is by the length of this forced-floating cylinder and forced-floating bar and control, and then upper outside punching on top shoe and the upper interior shaping bottom dead center position that rushes also are controlled, guarantee dimensional accuracy after shaping,
Demoulding state: the cylinder that floats drives float plate descending, takes blame for others and drives negative template descending, due to spacing to product of lower internal fixtion punching, makes product cannot be descending, and then pulls out product by under former, and now product is locked and rushes in upper; Then top shoe is up, now upper outsidely rushes piston cylinder inflation, and make the upper outside end that sweeps away prop up product all the time and be pressed on lower internal fixtion and rush to, in the up process of top shoe, upper interior punching pulls away product, then up while of upper outside punching and upper interior punching, realizes product stripping.
Former is provided with the step-like annular shaping powder metallurgy products (product has outer step structure) of step:
Shaping state: taking blame for others drives negative template to go upward to top dead centre by lower pulling plate, lower link, and the cylinder that floats drives float plate to go upward to top dead centre, makes lower outside floating punch, plug stretches in former; Cavity side cylinder, the piston rod of float plate side cylinder all stretches out, make cushion block on former be positioned at above former lower cushion block, in float plate, cushion block is positioned at above float plate lower cushion block;
Then top shoe drive upper outside punching and upper in sweep away row, in the descending process of top shoe, upper outside piston cylinder air inlet, make the upper outside punching that connects with upper outer piston relative upper in rush at down and stretch out, until be pressed in former by powder metallurgy product, in now going up, rush not contact product;
Top shoe continues descending, now, due to lower outside floating punch, the punching of lower internal fixtion spacing, upper outside punching cannot continue descending, and its relative powder metallurgy product is relatively motionless, upper outsidely rushes piston and upper outsidely rushes gap between cylinder bottom and reduce gradually, and upper interior punching is stretched in product;
Top shoe continues descending, rush piston when upper outside and upper outsidely rush between cylinder bottom after gapless, descending the while of upper outside punching and upper interior punching, former is due to step, the downforce of upper outside punching can be subject to, and then promote descending certain distance with upper outside punching, until cushion block props up negative template lower cushion block on negative template, and then negative template is supported by float plate, and and then the relative position of final former step surface and floating punch is fixed, float plate is continuous descendingly finally makes cushion block in the float plate of float plate prop up float plate lower cushion block, and then it is spacing to the shaping lower dead center of float plate, guarantee the bottom basic size of product,
In the process, top shoe constantly descending, the piston rod of forced-floating cylinder is made to prop up forced-floating bar, between the piston rod of forced-floating cylinder and cylinder bottom, gap constantly reduces, to promote after gapless between the piston rod of cylinder and its cylinder bottom until float float plate and on floating punch move down, again because the distance between top shoe and float plate is by the length of this forced-floating cylinder and forced-floating bar and control, and then upper outside punching on top shoe and the upper interior shaping bottom dead center position that rushes also are controlled, guarantee product top basic size precision;
Because punching upper outside in this reforming process, upper Nei Chong, lower floating punch and associated member all move with shaping action, and then achieve floating shaping, make product density region consistent.
