Embodiment
Below in conjunction with the accompanying drawings and embodiment be described in detail the present invention.
The main contents of the present invention include：1) a kind of ship machine connecting rod forging blanking mold；2) a kind of ship machine connecting rod forging system
The application method of mold tool.
As shown in figure 1, a kind of ship machine connecting rod forging blanking mold, it is adaptable to argosy machine connecting rod, the flattening system of dish
Mold have, the mould include upper mould 9, lower floating die 5, core 8, spring 3, lower mould base 2, fixed block 1, guide pillar 4, bolt 7,
Nut 6；Upper mould 9 is fixed on the top shoe of forcing press, and lower mould base 2 is fixed on forcing press lower table, and fixed block 3 is fixed
On lower mould base 2, the lower end of core 8 is fixed on fixed block 1；The upper end of core 8 passes through the through hole of lower floating die 5；Under described
Floating die 5 is connected by guide pillar 4 with lower mould base 2, the outside sheathed spring 3 of guide pillar 4 between lower floating die 5 and lower mould base 2；Under
The upper end of floating die 5 sets multiple columns 10；Column 10 it is similar to the gabarit of workpiece to the profile constituted above lower floating die 5 with
Just workpiece is positioned；Also include caging bolt 7, described one end of caging bolt 7 is fixed on lower mould base 2, and other end is passed through
Locked after lower floating die 5 by nut 6；The outer sheathed spring 3 of caging bolt 7.
To ensure uniform force, the column 10 is the center of circle with core 8, is uniformly arranged.
For further locking workpiece, the sidepiece of column 10 sets the screwed hole 11 of multiple insertions, and clamping screw is tightened on
Abutted in screwed hole and with workpiece.
The fixed block 1 of the present invention functions not only as the fixed component of core 8, also as a kind of positioning element, when workpiece is opened
When beginning moves downward, core ought be floated downward first in the groove corresponding with core shape and position formed below of workpiece
After the lower end of dynamic model 5 is contacted with fixed block 1, further moving down for lower floating die 5 is limited, therefore, flattening step is entered, this
When, still within the workpiece, the shape and position that so not only ensure that groove will not be destroyed core 8 because flattening technique, and right
Workpiece is further positioned, it is ensured that workpiece flatten after shape it is accurate.
The application method of the forging blanking mold that floats, it is characterised in that comprise the following steps that：
