Description
Technical field
The utility model is related to metal material Technology of Plastic Processing fields, more specifically to a kind of clutch disk hub
The block forging mold of piece.
Background technology
Clutch disk hub piece is the key member on automobile clutch, and the height of machining accuracy and intensity is to automatic clutch
There are direct influence in the performance of device and service life.The production method of hub is mostly two kinds of common forging and casting at present
Processing method, wherein using casting technique production clutch disk hub piece part mechanical property and make aspect of performance compared to
There is a big difference for forge piece, therefore it is more universal to forge processed and applied.
Forging is divided into open die forging, die forging, rolling ring and special forging etc. in industry at present, and wherein open die forging is not suitable for batch
Larger forging；Special forging needs to produce using professional equipment, and equipment investment is big；Die forging is divided into closed die forging and open die
Forging, is also easy to produce overlap, the utilization rate of material is low using open die forging, impressing forging part；Closed die forging does not have overlap, and stock utilization is high, but
It is the extrusion die for mainly using the locking of the elastic elements such as nitrogen gas spring, butterfly spring that can divide cavity plate using closed die forging, the mould
It is small to have clamping pressure, is adapted only to small-sized forging manufacture, and can not achieve the Bidirectional-squeezing of mold, processing efficiency is low, especially right
Still there is prodigious optimization space for the high quality processing of clutch disk hub piece.
Through retrieval, have a large amount of patent disclosures, such as Chinese Patent Application No. about closed-die forging technological improvement：
2016103402585, the applying date：On May 20th, 2016, invention and created name are：A kind of closed-die extrusion forging technology mold, this application
Case includes rigid die holder, floating cavity die, extruding punch and locking click-on mechanism, and rigid die holder includes upper platform sling, upper padding plate, upper solid
Fixed board, outer bush, outer guiding post, bottom plate, lower bolster and lower plate；Floating cavity die includes upper float plate, upper cavity die, lower floating
Plate and lower die；Extruding punch includes upper male mould and lower punch；It includes claw and lever mechanism to lock click-on mechanism；Mold passes through lock
Tight click-on mechanism realizes the connection of upper float plate and lower float plate, the movement by locking click-on mechanism realize mold die sinking and
Molding.
For another example Chinese Patent Application No.：2015100590408, the applying date：On 2 4th, 2015, invention and created name was：
A kind of closed-die extrusion forging technology mold, this application connect upper and lower die socket using link mechanism, realize upper and lower halving cavity die
It opens and is closed with locking, when mold downlink, left and right draft link is rotated into mould, and upper cavity die presses to form enclosed type with lower cavity die
Chamber completes block forging in punch-pin moves downward, and when upper mold returns, left and right draft link is rotated to outside mould, passes through the company of locking
It is automatically opened when linkage makes die holder rise, realizes that upper and lower cavity plate separation realizes multidirectional close by adding horizontal lateral punch-pin
Plug forging.
The above application case each contributes to increase clamping pressure, improves forging quality, but there is still a need for more abundant in industry
Mould structure form, to further application easy to produce.
