As shown in Figure 3 and Figure 4, the punch of the present embodiment mounting structure of loosing core, comprise upper die component and lower membrane module, upper die component comprises upper bolster 101, upper bolster 101 bottoms are equipped with punch retainer backing plate 102, punch retainer 104 is installed on punch retainer backing plate 102, the stripper backing plate 105 of stripper 106 is installed on punch retainer 104 in addition; Lower membrane module comprises die shoe 111, and die block backing plate 110 is installed on die shoe 111, and die block 109 is installed on die block backing plate 110, is equipped with and looses core 107 by back-moving spring 108 on die block 109; The bottom that is positioned at upper bolster 101 also is equipped with and makes bar holder 14 by bolt 13, beats on bar holder 14 to be equipped with and makes bar 15, makes bar 15 and is fixed on upper bolster 101 by playing top component 12; An end that is positioned at die shoe 111 is equipped with the first rotating shaft holder 21 by securing member, the first rotating shaft holder 21 is provided with the first rotating shaft 20, be positioned on the die shoe 111 of the first rotating shaft holder 21 1 sides, by securing member, connecting rod holder 19 also be installed, the top of connecting rod holder 19 is provided with the second rotating shaft 16; Die block 109 is equipped with the holder 23 of loosing core, 107 ends that are installed on the holder 23 of loosing core of loosing core, and the other end of the holder 23 of loosing core arranges oval-shaped slot, and the 3rd rotating shaft 22 is installed in oval-shaped slot; Be equipped with between the first rotating shaft 20 and the second rotating shaft 16 between first connecting rod 18, the second rotating shafts 16 and the 3rd rotating shaft 22 second connecting rod 24 is installed.
Beat the top that bar 15 is positioned at the second rotating shaft 16 installation sites.
Beat bar 15 and the second rotating shaft 16 in the vertical directions and be positioned at same axial location.
The top of connecting rod holder 19 is provided with arc groove 17, the second rotating shafts 16 and is installed in arc groove 17.
In actual use procedure, as shown in Figure 3 and Figure 4, adopt double connecting rod, first connecting rod 18 1 ends are fixed on the first rotating shaft 20, and the first rotating shaft 20 is arranged in the first rotating shaft holder 21, is not moved; One end of the other end of first connecting rod 18 and second connecting rod 24 is installed on the second rotating shaft 16 simultaneously.15 dozens, the bar of beating that is contained on upper die component is connected with second connecting rod at first connecting rod 18 on the bearing that connects, under the effect of making bar 15, first connecting rod 18 and second connecting rod 24 are all in the second rotating shaft 16 rotations, and along arc groove 17 diagrams, slide left, the 3rd rotating shaft 22 is slided left along the Long Circle groove in the holder 23 of loosing core, driving simultaneously looses core 107 slides into operating position left, and after moulding finished, two connecting rods reset to initial position under the effect of back-moving spring 108.Punch press is completed jig frequency one time.
The utility model employing double link drives 107 work of loosing core.Make 15 dozens of bearings on the second rotating shaft 16 of bar with what be contained in patrix, under the effect of making bar 15, two connecting rods, loosing core 107 is moved to the left simultaneously, due to two rotating shafts being arranged, 107 displacements of loosing core and beat bar 15 displacement ratios and greatly improve.Effectively guaranteed to loose core 107 operating distances and only large increase beat the stroke of bar, discharging.The assurance mould is not worked under large discharging stroke, guarantee simultaneously the stability that mould is produced.
As shown in Figure 3, the distance of the sliding stroke e of the 3rd rotating shaft impulse stroke b that equals to loose core,
Loose core 107 in double link, beat under the effect of bar 15, the 11.25mm(that slides the left impulse stroke b of loosing core) to operating position.Opening stroke, discharging stroke be as shown in Figure 3: (material lift height c is in the 3.8mm situation)
(1): the opening stroke of punch press is minimum to be needed (the sliding up and down stroke d of 6.0mm＜second rotating shaft 〉+3.8mm＜material lift stroke c 〉) * 2=19.6mm.
(2): discharging stroke f needs (the sliding up and down stroke d of 6.0mm＜second rotating shaft 〉+0.5mm＜add safety travel 〉)=6.5mm.
Be compared with the prior art, 107 strokes need 11.25mm in the situation that the work that guarantees is loosed core, and greatly reduce the required opening stroke of discharging stroke and punch press.Can find out that the utility model is dwindling 35% aspect the opening stroke of punch press, discharging stroke aspect dwindles 45%.Thereby improved the Stability and dependability that mould uses, extended die life.
Above description is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range, referring to claim, within protection domain of the present utility model, can be done any type of modification.
