Be provided with die 35 on the die shoe 1, be provided with screw hole on the described die shoe 1, the backgauge pin-and-hole, jogger hole, link together with die shoe 1 by screw 34 and pin stop 33 above the described die 35, be provided with blank holder 32 in die 35 inside, be provided with punch 29 in blank holder 32 inside, punch 29 inside are provided with die plate insert 28, its die 35 links together below by screw 31 and blank holder 32, die shoe 1 links together by screw 31 with punch 29, on described die shoe 1, also be provided with support 24 and cushion block 25, support 24 and cushion block 25 link together by screw screw 23 and die shoe 1, the circular hole bottom also is provided with cover plate 30 in the middle of described die shoe 1, cover plate 30 links together by sunk screw 27 and die shoe 1, described die shoe 1 bottom also is provided with push rod 26,1 liang of angle of described die shoe also is provided with guide pillar 3, and described punch 29 end faces are than the low 3mm of blanking punch-die 21 end faces.

Part is a simple circle and is axially symmetrical stamping-out flange spare, and maximum gauge can directly obtain by blanking, inside needs centre of punch heart hole and flange, and the stamping-out of endoporus can produce waste material, so the die 25 of blanking should be fixed on the die shoe 1 generally, the die 35 of punching is fixed on the die shoe 1, the die 35 of punching also is fixed on the punch 29, finish so first blanking and punching, again along with the continuation of mould action finishing drawing and flange, and the waste material that punching produces can directly be discharged outside the mould by the through hole that communicates with die 35.Billot only has 1.5mm thinner, and stamping parts is less, quality requirement is general, belong to common stamping, so can carry out discharging with elastic tripper, punch-die 21 is finished the binder action with the pressure of stripper 6 before can utilizing simultaneously elastic device to realize stamping-out, to guarantee the flatness of workpiece, again because the form of blank billot is sent mould to, output is large, correct location when adopting a pin stop 33 to finish billot to send to and even correct feeding step pitch, it is simpler to rush simultaneously the part structure, so get final product with manual feeding, consider on the guidance mode of die holder up and down, dimension precision requirement is more general, produces in enormous quantities, can finish the correct stamping-out location of upper and lower mould with the form that guide pillar 3 and guide pin bushing 4 cooperate.

The mold work process is, billot is sent in 6 times strip grooves of positive stripper, lie on 35 of the dies, and by a side of groove, press ram is descending with patrix, and punch-die 21 lower surfaces at first contact billot, and push down billot with blank holder 32, elder generation's blanking, again punching, rear pull and stretch, flange; After flange finishes, in order to guarantee the flatness of workpiece, need to carry out trimming, stop a moment patrix backhaul after finishing when namely arriving lowest part under the patrix.Billot behind the blanking is unloaded from punch-die 21 by positive stripper 6, the workpiece of drawing and forming is laid by 16-push rod 17-kicker 9 rigidity from punch-die 21 that re-packs by the bar 14 of beating on the forcing press, after by hand workpiece being taken away, send a step pitch forward with billot, carry out the production of next workpiece, can finish simultaneously blanking, punching, pull and stretch, flange four procedures are realized producing continuously, adopt manual feeding style, material guide device adopts the guide pin, mould adopts spring-loaded stripping rigidity piece, adopt the guidance mode of rear side guide pillar, production efficient and quality are high.

According to die shut height, work surface of punching machine size etc., select the JC23-40F gap-framepress, and prepare cushion block at work top, the selection of pressing equipment is an important indicator in Sheet Metal Forming Technology and the Design of Dies, be directly connected to the safe handling of pressing equipment, can Sheet Metal Forming Technology realize and die life smoothly, product quality, production efficiency, the problems such as cost height, described mould can be finished four operations simultaneously on same position, and the workpiece accuracy of going out is high, production efficiency is high, the position of blanking part hole to profile guaranteed easily the mould wearability, toughness, hardness and Heat stability is good, the quality of fit of each part, positional precision, kinematic accuracy is good, assembling is smoothly without any interference, and it is also comparatively convenient to safeguard and dismantle.
