Core Working Principle of Walking Beam Conveying
One complete cycle of the hydraulic synchronized walking beam mechanism includes 4 steps:
1. The movable beam lifts integrally to separate axles completely from fixed supports;
2. The movable beam moves forward by a fixed step distance (commonly 430~800mm, customized according to axle length);
3. The movable beam descends steadily to place axles back on fixed supports;
4. The movable beam retreats and resets to finish one feeding stroke.
The axles are supported overhead at multiple points without local concentrated compression. No sliding friction occurs during conveying for long shaft parts, which greatly reduces bending deformation after heat treatment.
