Description
Technical field
The present invention relates to the technical field of forging of aero-engine drum barrel forging development, especially relate to the technical field of forging of TC4 alloy large-size drum barrel forging, be specially the forging mold of TC4 alloy large-size drum barrel forging.
Background technology
The in the past production of drum barrel forging mainly is by open die forging or grinds the mode of encircling and carry out, and the forging mode of general open die forging, stone roller ring is multiplex in the relatively simple forging production of shape, and its stock utilization is low.A kind of drum barrel forging for aero-engine, its diameter is large, thin-walled is thick (depth-width ratio is 7), and the cross section is irregular, adopt the mode of traditional whole employing open die forgings or stone roller ring to process, not only material use is low for it, and working (machining) efficiency is low, and difficulty of processing is large, machining accuracy is low, and processing cost is high.
Summary of the invention
For the problems referred to above, the invention provides the forging mold of TC4 alloy large-size drum barrel forging, the forging processing of adopting mould of the present invention to carry out TC4 alloy large-size drum barrel forging can greatly improve stock utilization, improves working (machining) efficiency and guarantee machining accuracy.
Its technical scheme is such, it comprises upper bolster and die shoe, the counterdie backing plate is installed on the described die shoe, under the described upper bolster patrix is installed, on the described counterdie backing plate lower die structure is installed, it is characterized in that: described lower die structure comprises counterdie, counterdie jacking block and retainer ring, described retainer ring be installed on the described counterdie backing plate and by the locating ring face diameter of described counterdie backing plate to spacing, described counterdie is coaxially installed in the described retainer ring and by interior hexagonal cylindrical screw two and is installed on the described counterdie backing plate, described counterdie has axial installation through hole, in the described axial installation through hole ejector beam two is installed, described ejector beam two runs through described counterdie backing plate from top to bottom successively, die shoe, described counterdie jacking block bottom is equipped with ejector beam one by interior hexagonal cylindrical screw one, described counterdie jacking block spiral-lock is on described counterdie, and described ejector beam one stretches in the described axial installation through hole from top to bottom, and described ejector beam one bottom contacts with the top of described ejector beam two.
It is further characterized in that:
Have the counterdie locating slot on the described counterdie backing plate, described counterdie is installed in the described counterdie locating slot;
Described ejector beam two is by its step surface and described counterdie backing plate axial limiting;
Described retainer ring is made by the Cr40 material, and described upper bolster, die shoe, upper die and lower die jacking block, counterdie, ejector beam one, ejector beam two, counterdie backing plate are made by the 5CrNiMo material.
Adopt mould of the present invention to carry out the forging processing of TC4 alloy large-size drum barrel forging, its beneficial effect is: it can greatly improve stock utilization, improves working (machining) efficiency, guarantees machining accuracy, reduce production costs; In addition, the lower die structure of mould of the present invention has adopted split-type structural, not only is convenient to making and the installation of mould, and die forging finish after its counterdie jacking block under the effect of ejector beam, can easily forging be ejected discharging, also can improve working (machining) efficiency; And adopt split-type structural can reduce the use of mold materials, and alleviate mold weight, more be convenient to making and the installation of mould, reduce die cost.
