Abstract
The invention relates to the technical field of metal mechanism processing, and in particular relates to a novel formation process of a flywheel of an engine. The process is that a cold plastic processing process is carried out; round steel is used as a raw material and processed by horizontally rotating; the processed blank is positioned into a horizontal rotating die; a hub and a spoke of the flywheel are formed by the horizontal rotating process; meanwhile, a rim of the flywheel is formed through an external two-way guide wheel; therefore, the static balancing requirement can be met; a large amount of processes can be saved; the turning processing is avoided; materials can be saved; meanwhile, the problems of high pollution, high energy consumption and high emission in cast production can be solved.
Description
Technical field
The present invention relates to metal machining technical field, especially a kind of engine flywheel forming process.
Background technology
Flywheel belongs to hub class part, flywheel is mainly used in energy absorption in engine mechanical power train and release, it is indispensable stored energy part, the freewheel mainly foundry goods such as HT250 in conventional fabrication processes, to be cast blank by casting technique, then through turnery processing, the operations such as calibration balance complete, waste lot of materials, increase production cost, and the heavier easy generation cracking phenomena of flywheel, Foundry Production is because of high melt simultaneously, casting process and relate to high energy consumption, the problems such as high pollution and high cost, its industry production capacity and scale have been subject to national regulation and control and restriction.Although existing casting process can meet the requirement of flywheel outer shape, but because cast-internal tissue exists density unevenness, hardness differs, the defect such as easily produce bubble, be mingled with, blank can not meet static balance requirement after turning, also will increase static balance and duplicate removal technique of repeatedly holing.
Summary of the invention
The technical problem to be solved in the present invention is: to be cast blank by casting technique to overcome in prior art flywheel, then complete through the operation such as turnery processing, calibration balance, waste lot of materials, increases production cost, and heavier easy generations of flywheel is ftractureed, blank can not meet static balance requirement after turning, also will increase static balance and duplicate removal technique of repeatedly holing, and Foundry Production is because of high melt, casting process and relate to high energy consumption, the problems such as high pollution and high cost, the invention provides a kind of engine flywheel forming process, this technique adopts cold conditions plastic working technique, adopt round steel as blank, forming step is revolved by flat, the blank processed is put into put down and revolve mould, the wheel hub of flywheel and the shaping of spoke is completed by flat lathe turner's skill, complete the shaping of the wheel rim of flywheel by external two-way guide wheel simultaneously, meet static balance requirement, save a lot of operation, do not need to carry out turnery processing, save material, reduce production cost, also solve the high pollution in castings production simultaneously, high energy consumption and maximum discharge problem.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of engine flywheel forming process, this technique comprises blanking step, forming step, punch steps and finish turning endoporus step successively, this technique adopts cold conditions plastic working technique, and adopt round steel as blank in this blanking step, this forming step is made up of following steps successively:
Turning center locating hole step;
First surface is flat revolves forming step, and blank previous step processed is put into and flatly revolved mould, and the first surface being completed the wheel hub of flywheel and spoke by flat lathe turner's skill is shaping, and the first surface simultaneously completing the wheel rim of flywheel by external two-way guide wheel is shaping;
Put down for second and revolve forming step, overturn workpiece, repeat previous step, second that completes flywheel shaping;
Particularly, to be that multi-pass is flat revolve described flat lathe turner's skill.
Particularly, be that three passages are flat when described flat lathe turner's skill first surface of completing flywheel is shaping to revolve.
Particularly, described flat lathe turner's skill complete second of flywheel shaping time to be that four-pass is flat revolve.
The invention has the beneficial effects as follows: the invention provides a kind of engine flywheel forming process, this technique adopts cold conditions plastic working technique, adopt round steel as blank, forming step is revolved by flat, the blank processed is put into put down and revolve mould, the wheel hub of flywheel and the shaping of spoke is completed by flat lathe turner's skill, complete the shaping of the wheel rim of flywheel by external two-way guide wheel simultaneously, meet static balance requirement, save a lot of operation, do not need to carry out turnery processing, save material, reduce production cost, also solve the high pollution in castings production simultaneously, high energy consumption and maximum discharge problem, and at least can digest the superfluous production capacity of 150,000 tons of cheap common low carbon steel every year, to be that multi-pass is flat revolve flat lathe turner's skill, and being that three passages are flat when the first surface that flat lathe turner's skill completes flywheel is shaping revolves, flat lathe turner's skill complete second of flywheel shaping time to be that four-pass is flat revolve, multi-pass processing is carried out to blank, continuously shaped, do not remove material, fall that this is effective.
To produce little bavin engine flywheel, produced by casting technique, choose HT250 foundry goods, before piece-production cost is about the non-machined of billet weight kg() * unit price of procurement (unit/part)=30*6=180 unit, produced by spinning process, choose Q235B round steel, before piece-production cost is about the non-machined of billet weight kg() * unit price of procurement (unit/part)+blanking expense (unit/part)+spinning expense (unit/part)=27*3.5+5+20=119.5 unit, every part cost reduces by 34%, greatly reduces production cost.
