A kind of clamping apparatus for planetary conical cone gear closed type hot die forging quick locking
Technical field
The utility model relates to for one
the clamping apparatus of planetary conical cone gear closed type hot die forging quick locking.
Background technology
Planetary conical cone gear is the part being used for transmitting power and distribution different rotating speeds in automobile differential device, can distribute different rotating speeds, meet the kinematic requirement of running car when automobile turning at nearside wheel and outboard wheel.The die forging of conventional planetary gear closed type hot uses the mechanical interlocking clamping system utilizing flexible member, after repeatedly closing, push rod contact surface is easy to wear, causes upper and lower mould to close not tight, in extrusion process, under the effect of tensile force, blank easily forms overlap, and then causes forging insufficient fill to form defect.
Summary of the invention
The utility model provides a kind of clamping apparatus for planetary conical cone gear closed type hot die forging quick locking, solves prior art Problems existing.
The technical solution adopted in the utility model is: a kind of clamping apparatus for planetary conical cone gear closed type hot die forging quick locking, comprise dynamic locked mode hook plate 1, dynamic locked mode hook plate supporting seat 2, extension spring 3, push rod supporting seat 4, push rod 5, hydraulic cylinder 6, hydraulic cylinder 6 drives the push rod 5 supported by push rod supporting seat 4, push rod 5 drives the dynamic locked mode hook plate 1 supported by dynamic locked mode hook plate supporting seat 2, dynamic locked mode hook plate 1 is connected with dynamic locked mode hook plate supporting seat 2 propeller boss, is connected with extension spring between push rod supporting seat 4 and dynamic locked mode hook plate 1.
The beneficial effects of the utility model: locked mode is still very firm after repeatedly closing, and can not produce overlap, forging forming is good.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, a kind of clamping apparatus for planetary conical cone gear closed type hot die forging quick locking of this utility model, a kind of clamping apparatus for planetary conical cone gear closed type hot die forging quick locking, comprise dynamic locked mode hook plate 1, dynamic locked mode hook plate supporting seat 2, extension spring 3, push rod supporting seat 4, push rod 5, hydraulic cylinder 6, hydraulic cylinder 6 drives the push rod 5 supported by push rod supporting seat 4, push rod 5 drives the dynamic locked mode hook plate 1 supported by dynamic locked mode hook plate supporting seat 2, dynamic locked mode hook plate 1 is connected with dynamic locked mode hook plate supporting seat 2 propeller boss, extension spring is connected with between push rod supporting seat 4 and dynamic locked mode hook plate 1.
When after Closed Extrusion mould matched moulds, the compression piston pressing hydraulic selector unlatching neighboring liquid cylinder pressure 6 moves, promote push rod 5 move inward and promote dynamic locked mode hook plate 2 up time rotation, the upper end of dynamic locked mode hook plate 2 compresses the patrix locked mode hook plate 1 of Closed Extrusion mould, patrix positioning sleeve is tightly fitted counterdie, and in the die cavity closed, upper punch is descending extrudes qualified forging.After press backhaul, start hydraulic selector, push rod 5 backhaul, under the effect of extension spring 3, dynamic locked mode hook plate 1 rotates and departs from patrix locked mode hook plate.After repeatedly Operating In Persistent Current Mode, push away 5 bars under the effect of hydraulic valve can automatically in move the wearing and tearing compensating contact surface.
