Die Cutting Machine Air Inflatable Shaft Maintenance Case

The reason for the case is that the axial torque force of air expansion is large, the gap between the original coupling and the key is generated, and the gap is getting larger and larger during operation, resulting in the relative movement of the shaft and the coupling, resulting in wear on the shaft. A rigid coupling is a torsionally rigid coupling that does not have any swing clearance even when subjected to load, and the rigid coupling transmits torque rigidly even when a load is generated by a deviation. The coupling has high requirements for the neutrality of the two shafts, and when the relative displacement of the two shafts exists, it will cause additional load in the machine, worsen the working situation, and wear out many parts.
On-site repair process of die cutting machine shaft wear:

1. Use oxygen acetylene for surface baking oil treatment;
2.  Surface polishing of the repair surface;
3. Measure the diameter size of the shaft and make sure that the reference surface on the shaft is not worn;
4.  Conduct empty test tooling to ensure that the tooling is suitable;
5.  Use absolute ethanol for surface cleaning to ensure that the surface is dry;
6.  Brush SD7000 release agent on the inner surface of the tooling;
7.  Mixing and applying materials SD7101H;
8.  Clamp the special fixture and heat the shaft end to make the material cure quickly;

 Dismantling of special tooling; Remove excess material, repair keys, and install keys in place, repair complete.
