Detailed description of the invention
Elaborate to embodiments of the invention below, the present embodiment is implemented under premised on technical solution of the present invention, give detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following embodiment.
As shown in Figure 1, the five beam four post pressing hydraulic machines of the present embodiment comprise top nut 1, entablature 2, upper cylinder 3, top shoe 4, column 5, cylindrical mould 6, middle fixed station 7, lower nut 8, low punch 9, sliding block 10, lower oil cylinder 11 and sill 12, described entablature 2, top shoe 4, column 5, middle fixed station 7, sliding block 10, sill 12 sets gradually, top nut 1 is fixed on the top of entablature 2, upper cylinder 3 is connected with top shoe 4, cylindrical mould 6 is arranged in middle fixed station 7 by lower nut 8, low punch 9 is connected with sliding block 10, lower oil cylinder 11 is connected with sliding block 10.
As shown in Figures 2 and 3, low punch 9 comprises the drift 91, pillar 92, sphere backing plate 93, sphere base 94 and the interior backing plate 95 that set gradually.
As shown in Figure 4 and Figure 5, mould changing device comprises jacking mechanism and mobile die changing mechanism; Described jacking mechanism comprises die change plate 131, first and rotates reductor 132, support 133, floating guide rail 134, guide rail wheel 135, lift cylinder 136, fixed stop 137 and base 138; Described die change block is fixed by screws in the upper plane of sliding block, guide rail wheel 135 is arranged on floating guide rail 134, die change block is positioned on guide rail wheel 135, lift cylinder 136 is arranged under floating guide rail 134, first rotates reductor 132 is connected by chain with guide rail wheel 135, lift cylinder 136 is fixed on base 138, fixed stop 137 is arranged at the edge of die change plate 131, first rotates reductor 132 is fixed on base 138 by support 133, and floating guide rail 134 is arranged on base 138 by alignment pin 139.
When five beam four post pressing hydraulic machines normally work, die change plate 131 is screwed the upper plane at sliding block, and the plane contact of die change plate 131 and interior backing plate 95, bears pressure; When needs die change, removing screw, floating guide rail 134 is pressurizeed by hydraulic oil, and floating guide rail 134 floats, and lifts whole low punch 9 device, now can carry out replacing low punch 9.
After the screw of low punch 9 removes; after floating guide rail 134 and guide rail wheel 135 lift by lift cylinder 136, die change plate 131 i.e. rotatable outside movement, and first rotates reductor 132 starts rotation; by chain drive, whole for low punch 9 device outwards can be moved in mobile die changing mechanism.
As shown in Figure 6, mobile die changing mechanism comprises mold-change trolley 141, road wheel 142, rotates running roller 143, second rotation reductor 144, side gear wheel 145, front and back gear wheel 146, driving speed reducer 147 and stationary cylinder 148; Described driving speed reducer 147 is arranged on mold-change trolley 141, road wheel 142 is arranged on four corners of mold-change trolley 141, rotating running roller 143 is positioned on mold-change trolley 141, second rotates reductor 144 is connected with rotation running roller 143, side gear wheel 145 is positioned at the side rotating running roller 143, front and back gear wheel 146 lays respectively at the rear and front end rotating running roller 143, and stationary cylinder 148 is arranged on mold-change trolley 141.Rotate running roller 143 and have two groups, be arranged at respectively on mold-change trolley 141.Can increase work efficiency.
During the present embodiment work; low punch 9 and die change plate 131 are fixed as a whole; when changing low punch 9; first the stressed screw that die change plate 131 is connected with five beam four post pressing hydraulic machines is removed, start lift cylinder 136, jack-up floating guide rail 134; at this moment guide rail wheel 135 can be rotated; now starting the first rotation reductor 132, first rotation reductor 132 drives guide rail wheel 135 to rotate by chain drive, low punch 9 can be rotated to together with die change plate 131 on the mobile die changing mechanism in left side.On mobile die changing mechanism second rotate reductor 144 simultaneously also driven rotary running roller 143 rotate; when low punch 9 contacts rotation running roller 143 with die change plate 131; rely on frictional force; can low punch 9 be rotated on mobile die changing mechanism completely; to rotate after running roller 143 and guide rail wheel 135 jack-up in same plane; on the left of mobile die changing mechanism, there is electromechanical stop on limit; the die change plate 131 of low punch is blocked; now the second rotation reductor 144 stops action; start driving speed reducer 147, whole mobile die changing mechanism forward direction can move to other place.
When low punch 9 and die change plate 131 are transferred on mobile die changing mechanism completely; driving speed reducer 147 drives whole mobile die changing mechanism walking; low punch 9 and die change plate 131 are moved on to one from the place away from main frame, and this place has lifting appliance low punch 9 can be hung, change.When mobile die changing mechanism moves stopping, stationary cylinder 148 action, drive alignment pin 139 descending, alignment pin 139 comes downwards to ground locating hole fixing point, and fixed safely by whole mobile die changing mechanism, mobile die changing mechanism there will not be slippage.
