When forging mold 1 separates with forging lower mold 3, will by the gap between overlap storehouse portion 9 and overlap
Forging takes out, and this design eliminates liftout attachment.
Using above-mentioned forging mold to carry out the forging method of hob cutter for shield machine cutter ring, it specifically comprises the following steps that
Step one, intercepts part round bar, adds hot piercing, for producing circular material blank base.This step is cut
The general diameter of round bar taken is respectively less than hob cutter for shield machine cutter ring diameter, and the round bar intercepted is heated to
1100 DEG C～1180 DEG C, it is punched out process.
Step 2, carries out reaming to required circular material blank size by the blank in step one.In this step, annular
Blank external diameter is slightly less than hob cutter for shield machine cutter ring diameter, and circular material blank internal diameter is slightly larger than hob cutter for shield machine cutter ring
Diameter, it is therefore an objective to facilitate the blank filling in type, step one of blank through temperature rise 1100～1180 DEG C, launch reaming
Process.
Step 3, carries out roughing by the circular material blank in step 2, carries out rounding in circular material blank edge
Processing, fillet size is R15～20mm.In this step, comprehend at rounding and make blank in forming process
The probability producing fold defect is substantially reduced.
Step 4, launches the forming process of forging: carry out being heated to required forging by circular material blank described in step 3
After temperature, it is placed in forging mold and forges, make forging.In described step 4, forging mold needs pre-
Heat, forging mold (forging mold 1 and forging lower mold 3) preheating temperature is 150 DEG C～300 DEG C,
Circular material blank is heated to 1100 DEG C～1200 DEG C (preferably 1120 DEG C～1150 DEG C), by circular material blank from stove
Take out and be transported to mould by asbestos parcel, after circular material blank enters mould, launch forging process.
Step 5, after molding described in step 4, forging mold 1, forging lower mold 3 separate, and take
Go out forging；Forging mold 1 is separated by four key grooves with forging lower mold 3, by overlap with fly
Forging is taken out in gap between the groove of limit.
Step 6, sends into the forging in step 5 in annealing furnace and carries out furnace cooling, prevents that cooling rate is too fast to be caused
Forging cracking.
In order to prevent blank from aoxidizing, in said process, all heating processes are all carried out in vacuum drying oven.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all at this
Any modification, equivalent substitution and improvement etc. made within the spirit of utility model and principle, should be included in this
Within the protection domain of utility model.
