Description
Technical field
The utility model relates to eccentric shaft technical field of forging more particularly to a kind of eccentric shaft forging dies.
Background technique
The outer circle workpiece without coincidence parallel with the axis of outer circle, referred to as eccentric shaft.Eccentric shaft is generally by eccentric orfice
It is fixed on electric machine rotational axis, in electric motor starting, does cam movement.Therefore it is widely used in automobile, engine, pump etc..
Forging die is the general designation that metal carries out mould therefor when bulk forming under hot or cold conditions.
In forging, metal stock is placed in forging die thorax existing forging equipment, deep when upper mold hammers metal stock
Deep hole road is blocked in metal stock deformation around duct, and the air in deep hole road can not be discharged, and metal stock can not be completely filled with
Deep hole road causes the reinforcing rib of product to form bad, missing occurs, collapse situations such as angle.
In view of the above-mentioned problems, patent publication No. CN204934452U discloses a kind of forging die, not only metal stock can be complete
It is full of deep hole road entirely, while metal stock can be kept the temperature, prevents it just cooling before forging molding.
However in actual operation, above-mentioned patent has the disadvantage that installs upper mold by voussoir under in dovetail groove
Mould is the interference fit realization that voussoir, upper die and lower die and dovetail groove is utilized in fact, and this mounting means is in lasting forging
In production, the abrasion loss of voussoir is larger, is easy because abrasion reduces the degree of interference connection, to easily cause upper die and lower die
Between position deviation, and the updating maintenance mode of voussoir is cumbersome, therefore is affected to forging, especially eccentric shaft
The slight deviations of forging die, upper mold and lower die will substantially reduce the forging quality of eccentric shaft, while the replacement of forging die is also cumbersome, because
This needs to design the eccentric shaft forging die that a kind of connection type is stable, maintains easily.
Utility model content
