Abstract
The present invention relates to one kind to forge gear manufacture craft, described manufacture craft includes sawing, blank shove charge heating, pressure cake, compressing, milling train roll tooth, punching, normalized treatment, quenching and examine storage, the present invention have technique it is simple, into the advantages of production cost is low, efficiency high.
Description
Technical field
The invention belongs to crane Gear Production technology field, and in particular to one kind forging gear manufacture craft.
Background technology
Current domestic die forging crane Gear Production technique all need reheating and gear can not in forging process into
Shape, its technological process of production be mostly blanking, heating, upset, reheating, descaling, enter die forming, punching, heat treatment,
Trimming, enter roughcast warehouse, roughing, quenched, finishing, finished product storage, some even also needs to heat three times, and this certainly will just make
It is unfavorable for producer and user into production cost is high, efficiency is low etc. to compete in current fierce market competition.
The content of the invention
There is provided it is an object of the invention to overcome the deficiencies in the prior art a kind of technique it is simple, into production cost is low, efficiency
High forging gear manufacture craft.
The technical scheme is that：One kind forging gear manufacture craft, described manufacture craft comprise the following steps：
Step 1：Sawing, the raw material for calculating weight are cut with sawing machine and do upper sign；
Step 2：Blank shove charge is heated, and raw material is uniformly placed in heating furnace, is heated to 1230-1250 DEG C, and controls insulation
Time；
Step 3：Cake is pressed, the raw material after heating is forged into the cake for formulating size on forging press；
Step 4：It is compressing, the cake forged and pressed is pressed into the thickness of formulation using mould on forging press；
Step 5：Milling train rolls tooth, and compressing cake is rolled into using gear die on milling train with molding cutter by cylindrical
The size of formulation；
Step 6：Punching, the gear rolled is placed on special punching die, and rushed centre bore with special drift
It is good；
Step 7：Normalized treatment, the gear of made centre bore is eliminated into internal stress using normalized treatment；
Step 8：Quenching, the gear mesh flank of tooth after normalized treatment is subjected to Quenching Treatment；
Step 9：Storage is examined, the gear after quenching is tested under the state of cooling, and qualified gear is put into finished product
Storehouse.
The present invention has advantages below：This technique makes the quality of gear increase, and is sawed from raw material using numerical control horizontal
Carry out coming out of the stove after heating furnace is heated to 1230 DEG C after bed blanking, removed oxide skin using descale machinery, upper press pressure circle
Cake, enter mould, turn milling train, again upper press punching, normalized treatment, improving the interior tissue and toughness of wheel, improve
Production efficiency, best flank of tooth Quenching Treatment, has saved cost.
Embodiment
With reference to embodiment, the present invention is further illustrated.
Embodiment 1
One kind forging gear manufacture craft, described manufacture craft comprise the following steps：Step 1：Sawing, weight will be calculated
The raw material of amount are cut with sawing machine and do upper sign；Step 2：Blank shove charge is heated, and raw material is uniformly placed in heating furnace, added
Heat controls soaking time to 1230-1250 DEG C；Step 3：Cake is pressed, the raw material after heating is forged into system on forging press
The cake being sized；Step 4：It is compressing, the cake forged and pressed is pressed into formulation on forging press using mould
Thickness；Step 5：Milling train rolls tooth, and compressing cake is utilized into gear die and molding cutter by cylindrical rolling on milling train
Into the size of formulation；Step 6：Punching, the gear rolled is placed on special punching die, and will with special drift
Centre bore is made；Step 7：Normalized treatment, the gear of made centre bore is eliminated into internal stress using normalized treatment；Step 8：Quench
Fire, the gear mesh flank of tooth after normalized treatment is subjected to Quenching Treatment；Step 9：Storage is examined, to the gear after quenching in cooling shape
Tested under state, and qualified gear is put into warehouse for finished product.
This technique makes the quality of gear increase, and adds from raw material using progress heating furnace after numerical control horizontal sawing machine blanking
Heat is removed oxide skin using descale machinery to coming out of the stove after 1230 DEG C, upper press pressure cake, enter mould, turn milling train,
Upper press punching, normalized treatment again, the interior tissue and toughness of wheel are improved, improve production efficiency, best flank of tooth quenching
Processing, has saved cost.
