Using the shaping dies of above-mentioned pulse ripple fagging, shaping dies and punching machine are installed in place, when upper die body exists
Downlink under the active force of punching machine, guide post initially enter guide sleeve, the correct position of the upper and lower die body of correcting, make upper die body at
Shape formpiston corresponds to the forming cavity of lower mold body former, and the positioning formpiston of upper die body corresponds to the positioning chamber of lower mold body former, and forming is used
Plate be placed in the grooving of lower die, upper die body and lower mold body mold, and forming generates first pulse ripple, on upper die body
Row, first stroke terminate, and position formpiston at this time and do not act on；Formed pulse ripple is sent be handed to lower die manually by second step
In positioning chamber in body；Formed pulse ripple is pressed in lower mold body in positioning chamber by upper die body downlink, positioning formpiston, on
Die body is continued traveling downwardly to forming second pulse ripple of intracavity forming, upper die body uplink, and second stroke terminates；Shape the latter
When pulse ripple, previous pulse ripple is manually located in positioning chamber, and so on complete pulse ripple fagging forming.
The beneficial effects of the present application are as follows: the forming die structure of the pulse ripple fagging of the application is reasonable, adapts to wide
It is general, with one shape pulse ripple to next pulse ripple forming position, greatly improve pulse ripple at
Form quality amount reduces and strikes the amount of repairing by hand, upper versatile in airplane parts molding, saves the time.
Attached drawing is described in further detail this application with reference to embodiments.
