After it is mounted on press crown, the scene of abrasion axis can be carried out in the case where not removing abrasion axis and related accessories
It repairs, it is simple and easy using first welding the method cut again when reparation, and the axis after repairing can reach original precision size again
It is required that.The present invention can greatly shorten the construction period, reduce maintenance cost, be reduced as far as repairing the shadow to wire body output
It rings, achieves good economic benefit.
Detailed description of the invention
Fig. 1 is the turning status diagram of lathe tool device of the present invention.
Specific embodiment
As shown in Figure 1, large pressing machine brake shaft of the present invention wears field repair lathe tool device, including peace
Pedestal 1 on press crown P, pedestal 1 are connected with first movement seat 3 by lateral displacement regulating mechanism 2, and first moves
Dynamic seat 3 is connected with the second Mobile base 5 by length travel regulating mechanism 4.Above-mentioned lateral displacement regulating mechanism 2 uses lead screw machine
Structure, length travel regulating mechanism 4 use linear guide.Further, the guide rail of dove-tail can be used in linear guide, can bear
Multidirectional stressed and clearance-adjustable.Lathe saddle 6 is installed, 7 cutting edge of lathe tool connected on lathe saddle 6 on second Mobile base 5
Below abrasion axis Q.
When carrying out field repair to large pressing machine brake wear axis using above-mentioned lathe tool device, following step is specifically included
It is rapid:
The first step, after preheating, in shaft end, fray is used common sequential welding soldering one week.Specifically, to prevent preheating temperature mistake
Height is symmetrically fast moved near the abrading section axis Q with two oxyacetylene torch welding torches before weldering, is slowly heated, is made the inside of axis
It can uniformly reach 150 DEG C with surface temperature；Then, using contravariant CO2Gas shielded welding machine, DC reverse connection, low current are applied
Weldering, weld penetration is shallow, and weldering speed is fast, to guarantee interlayer temperature.Specific welding parameter is as shown in the table；
The width and thickness of above-mentioned layer depends on shaft end abrasion loss, and specific wear amount is bigger in principle.
The pedestal 1 of lathe tool device is mounted on press crown P by second step, the first and second Mobile base 3,5 of adjustment
Position is located at lathe tool 7 below brake shaft Q, and 7 cutting edge of lathe tool is made to be in contact with the soldering position of the first step；Usual situation
Under, it can be added gasket under pedestal 1 and carry out high fine-tuning.
Third step starts press brake, rotates axis Q, axis revolving speed directly depends on press machine itself and brakes
Device axis revolving speed, different pressures machine clutch shaft revolving speed is different, and generally 100 revs/min -200 revs/min are differed.When axis rotates, lathe tool
Shaft end position after 7 turning soldering disconnects pressure until shaft end fray reaches original brake shaft precision size requirement again
Power brake power supply terminates repair.
Above-mentioned turning process includes rough turn and smart car.Specifically, carry out rough turn, the smaller cutting speed of use first, it is larger into
Give amount (0.19 mm -0.21mm)；Then smart car is carried out, with biggish cutting speed, the lesser amount of feeding (0.08mm-
0.1mm).Depending on cutting speed need to be in conjunction with live brake shaft revolving speed.Cutting speed formula is as follows: Vc=(π d n)/1000,
In formula, Vc is cutting speed (m/s), and d is shaft diameter to be cut (mm), and n is workpiece rotational frequency (r/s).Amount of feeding formula is as follows: Vf
=fn, in formula, Vf is feed speed (mm/s), and n is axis revolving speed (r/s) to be cut, and f is the amount of feeding (mm).It the above-mentioned amount of feeding and cuts
Speed is cut by manually adjusting.
