The utility model is used in the progressive die, and as shown in Figure 2, upper mounted plate 101 is equivalent to the train wheel bridge 22 in the progressive die, and inserted link 102 1 ends are connected with upper padding plate 21, and the other end passes baffle plate 23 and stripper plate 24; Bottom plate 109 is equivalent to the lower bolster 27 in the progressive die, and slide block 110 all is arranged in lower bolster 26 with block 105.Simultaneously, on strip 1, want stamping-out bullport a, b, c etc., the distance between the bullport will equate with the distance between feeding pin 111 and the stopping pin 104.Under the die opening state, slide block 110 nestles up block 105 under the active force of spring 107 and screw 106, and stopping pin 104 is in the bullport a of strip 1, and feeding pin 111 is in the bullport b of strip 1.

As shown in Figure 3, during matched moulds, the top shoe of punch press drives whole patrix and moves downward, and the projection 103 on the inserted link 102 is contact slipper 110 just, and still in the bullport a of strip 1, feeding pin 111 is still in the bullport b of strip 1 for stopping pin 104; The punch press top shoe continues to drive patrix and moves downward, and the projection 103 on the inserted link 102 forces slide block 110 to the direction motion away from block 105, and slide block 110 drives feeding pin 111 motion together; The limit of bullport b in the strip 1 is run on the inclined-plane of feeding pin 111, by strip 1 to pressing down.

As shown in Figure 4, the punch press top shoe continues to drive patrix and moves downward, and feeding pin 111 falls back on the lower end of strip 1, follows slide block 110 and continues to the direction motion away from block 105, and stopping pin 104 still is stuck in the bullport a of strip 1.

As shown in Figure 5; The punch press top shoe continues to drive patrix and moves downward, and the straight flange of the projection 103 on the inserted link 102 touches the straight flange of slide block 110, slide block 110 stop motions; Feeding pin 111 is under the active force of wire spring 108; Upwards buoyance lift snaps in the bullport c of strip 1, and this moment, stopping pin 104 was still in the bullport a of strip 1; Stripper plate 24 touches strip 1, prepares to press down feeding pin 111 and stopping pin 104.

As shown in Figure 6, the punch press top shoe continues to move downward, and stripper plate 24 presses down strip 1, feeding pin 111 and stopping pin 104, and feeding this moment pin 111 is in the bullport c of strip 1, and stopping pin 104 is still in the bullport a of strip 1.The punch press top shoe continues to move downward, when arriving bottom dead centre, and mould closes, following mode slider 110, feeding pin 111, stopping pin 104 have no action, and mould is accomplished the punching press action; At this moment, feeding pin 111 is in the bullport c of strip 1, and stopping pin 104 is still in the bullport a of strip 1.

As shown in Figure 7, during die sinking, the punch press top shoe moves upward, and drive upper padding plate 21, clamping plate 22, inserted link 102 move upward, and stripper plate 24 does not move under the active force of patrix spring, and slide block 110, feeding pin 111, stopping pin 104 also have no action; At this moment, feeding pin 111 is in the bullport c of strip 1, and stopping pin 104 is still in the bullport a of strip 1.The punch press top shoe continues to move upward, and high sleeves such as baffle plate 23, stripper plate 24 quilts are pulling upwards, and strip 1, feeding pin 111 and stopping pin 104 upwards float to peak simultaneously, and slide block 110 has no action; At this moment, the straight flange of projection 103 is about to break away from the straight flange of slide block 110, and feeding pin 111 is in the bullport c of strip 1, and stopping pin 104 is still in the bullport a of strip 1.

As shown in Figure 8; The punch press top shoe continues to move upward; At this moment, the straight flange of projection 103 breaks away from slide block 110 straight flanges, and slide block 110 is under the tension of spring 107, screw 106; Direction motion to block 105 places, feeding pin 111 spurs the direction motion of whole strip 1 to block 105 places through the straight flange that snaps in bullport c in the strip 1; The limit of bullport a in the strip 1 is run on the inclined-plane of stopping pin 104, by strip 1 pressed downward; Feeding pin 111 pulling strips 1 continue the direction motion to block 105 places, and stopping pin 104 all falls back on the lower end of strip 1, and at this moment, feeding pin 111 is still in the bullport c in strip 1.The punch press top shoe continue to drive patrix and moves upward, and this moment, the inclined-plane of projection 103 was about to break away from the inclined-plane of slide block 110, and slide block 110 stops to move right, and feeding finishes, and at this moment, stopping pin 104 snaps in the strip 1 in the bullport b, accomplishes a feeding step pitch.The punch press top shoe continues to move upward, and the inclined-plane of projection 103 breaks away from the inclined-plane of slide block 110 fully, and when the punch press top shoe moved to top dead-centre, die opening state as shown in Figure 2 was prepared the punching press in next feeding cycle and moved.

Utilize position relation and the expansion performance of resetting-mechanism between the cooperatively interacting of projection 103 and slide block 110 on the inserted link 102, feeding pin 111 and the stopping pin 104 to realize friction feeding; Can replace feeder with this device; Production cost drops into low; Therefore, realized the purpose that reduces production costs through the utility model.

To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined General Principle can realize under the situation of spirit that does not break away from the utility model or scope in other embodiments among this paper.Therefore, the utility model will can not be restricted to these embodiment shown in this paper, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
