Specific embodiment
Reference picture 1-4, a kind of selector fork stamping mold of employing combined die of the present utility model, including top mold frame 10
With lower mold holder 11, connected by lead column 12 between top mold frame 10 and lower mold holder 11, top mold frame 10 is fixedly connected with die shank 9, on
The lower surface of mould bases 10 is provided with upper padding plate 1 and the fixed plate 2 of punch 3, and top mold frame 10, upper padding plate 1 and the fixed plate 2 of punch 3 pass through
Screw is fixedly connected, and punch 3 is embedded with the fixed plate 2 of punch 3, and punch 3 is fixedly connected by screw with upper padding plate 1；Under described
The upper surface of mould bases 11 is provided with lower bolster 6 and die 5, and lower mold holder 11, lower bolster 6 are fixedly connected with die 5 by screw；Institute
The upper surface of die 5 stated is additionally provided with location-plate 4, shaft screw 8 and Positioning screw 7, and shaft screw 8 and Positioning screw 7 are distinguished
Positioned at the die cavity both sides of die 5, the one end of location-plate 4 is set on shaft screw 8, and other end is provided with for snapping in positioning spiral shell
The V-notch portion 4b of nail 7, the middle setting of location-plate 4 has for through shift fork shape cavity portion 4a of punch 3；Location-plate 4 and die
Gap is provided between 5；Location-plate 4 is also fixedly connected with operation handle 13.
Die 5 includes thering is forming cavity in the middle of inner ring portion 5b and outer ring portion 5a, inner ring portion 5b, and described inner ring portion 5b is embedded
In outer ring portion 5a, inner ring portion 5b and outer ring portion 5a adopts interference fit, and the magnitude of interference is 5mm.Inner ring portion 5b adopt
Cr12MoV makes, and outer ring portion 5a is made using 45 steel.When making die 5, type hole, milling are cut in advance by inner ring portion 5b wire cuttings
Material spilling hole, heat-treatment quenching tempering, is then heated to 420 DEG C by outer ring portion 5a so as to which endoporus expands 0.6mm, will there is 0.5mm mistakes
The inner ring portion 5b of the amount of being full of is put in outer ring portion 5a, forms hot anchor ear, is held tightly when to be cooled, then wire cutting essence is cut into type hole.
Because outer ring portion 5a is not through Quenching Treatment, so outer ring portion 5a can be drilled, convenient, fast, service life is changed
It is longer.
The working method of stamping mold of the present utility model, the blank of punching press is placed on first the upper surface of die 5, so
Afterwards by operation handle 13, location-plate 4 is driven to rotate around shaft screw 8, until Positioning screw 7 snaps onto V-notch portion 4b,
The fixation to blank is realized so as to pass through location-plate 4.Drive die shank 9 descending by drive mechanism, then drive top mold frame 10 to exist
Descending under the guide effect of lead column 12, the punch 3 of the lower section of top mold frame 10 passes through shift fork shape cavity portion 4a on location-plate 4, so
Afterwards with the matched moulds of die 5, the punch forming to blank is completed, the shift fork semi-finished product after shaping fall from die 5, collected.Once
After the completion of punching press, part of the upper die is up, then drives location-plate 4 to rotate backward around shaft screw 8 by operation handle 13, solves
Except the fixation to blank, then travelling stock, location-plate 4 is locked, and upper mould is descending, continues stamping procedure.The step of before repeating,
The punch forming to shift fork can be constantly completed, it is simple to operate, and firm position, shaping efficiency height.
