The second face is pressed again after completing a working cycles, and 3~4 secondary stress of pressure reach balance repeatedly in this way.Table after diamond saw blade crimping
Face out-of-flatness (has groove), needs to do back flat processing again, Hui Ping is that pinch roller 31 is adjusted to diamond saw plate plane to protrude face pressure
Turning over again after flat, press once can Hui Ping.The fine tuning of micro-adjusting mechanism 5 is mainly that diamond saw blade crimping time usually uses.Pass through
Crimping and Hui Ping have adjusted the stress distribution of diamond saw blade, reduce the beat of diamond saw blade, improve diamond saw blade
Intensity.
Operator generally presses 4 times repeatedly in Stress relief just can reach stress equilibrium.It is secondary that operator only needs note to roll
Number, shake with hands saw blade again without pressing repeatedly, see saw blade either with or without shaking, do not shake just balance, in this way will repeatedly many times,
Production efficiency is low.Phenomenon is often pressed through, if press through flanging to re-start stress equilibrium after exiting stress again again.One
As a piece of saw blade can only be repeated twice, be eliminated more than twice, to the more demanding of operator.A kind of outer circle of the invention is answered
Dynamic balance machine is stablized because of pressure only need to remember that number can.
According to the disclosure and teachings of the above specification, those skilled in the art in the invention can also be to above-mentioned embodiment party
Formula is changed and is modified.Therefore, the invention is not limited to the specific embodiments disclosed and described above, to of the invention
Some modifications and changes should also be as falling into the scope of the claims of the present invention.In addition, although being used in this specification
Some specific terms, these terms are merely for convenience of description, does not limit the present invention in any way.
