ã€China Aluminum Industry Network】 Characteristics of Aluminum Alloy Ring Rolling Recently, Quanyue Numerical Control Liugong's discussion on the rolling of annular forgings of aluminum alloy 5083 and other materials has been discussed with customers as follows. I hope to help readers.
Many manufacturers use vertical boring machines and horizontal boring machines for rolling aluminum alloy rings. However, many business owners do not have the years of experience and control capabilities of the Southwest Aluminum Group. Individual companies think that forging is rich in experience. Aluminum alloys forged with hammers have high density and are not loose. However, it is also very envious of the efficiency of the ring machine.
The characteristics of aluminum alloy ring rolling raise many questions:
1 How to determine the ratio of material expansion?
2 machine power is small? Rolling does not move it?
3 After the rolling, the shape of the ellipse or the end depression is larger, which is an operation problem?
4 is not familiar with the application of the mold?
5 is the ring rolling machine not suitable for aluminum alloy rolling?
The following describes some of the experiences gained by our Quanyue CNC and we look forward to communicating with you in the future:
1 Wall thickness ratio is not easy to be greater than 3;
The 2-die has a corresponding design of the draft angle and the mandrel, and it is better to communicate with the mold expert.
3 Before the aluminum alloy is forged, it needs to heat the bar skin after treatment;
(4) When the thickness of the blank needs to be controlled before the rolling of the ring blank is less than or equal to 20 mm, it is conducive to deformation of the material;
5 Don't overfast when rolling, pay attention to increase the pressure when the material flow is sufficient;
6 The amount of excess needs to be increased to prevent loosening caused by sticking and rolling after roughing.
7 too much graphite easily rolling idling, graphite small die-metering;

Ni-Cd Battery Emergency Exit Sign
These emergency exit signs usually equipped with recharged a 3.6V Ni-cd battery inside the hosing. It has up to 500 times backup powered. The battery is protected by a low voltage cut-off circuit. Also, the emergency escape signs specialized to use the fire-resistant housing at the engineering level. Upon failure of the normal utility power, an internal transfer switch provides emergency time for at least 90 minutes. The charger initiates powered back the battery in 24 hours. The exit sign is suitable for wall or ceiling mounting. Plus, there is an indicator light and a test button on the unit so that you can periodically check that it is functioning properly.
