        Common problem

        What are the unreasonable structural designs that cause cracks in induction quenching parts?

        Source: Time:2021-06-01 11:17:10 views:

        1. Product design, the same quenching section is uneven, resulting in uneven heating, and the most easily quenching of the transition section. 2. The wider the shoulders of the step axis, the more cracks of the shoulders; the smaller the shoulders r, the stress is concentrated, the temperature is not easy, and it is not easy to quench.

        3. There is a hole in the hardened layer, the larger the aperture, and the vortex is easily concentrated at the edge of the hole; the temperature is too high, easy to quench. A typical example is a quenching crack on the crank edge of the crankshaft of 1-1.
        4. The ends of the key channel are chamfered in the end of the shaft, and there are sharp corners on the parts. The current is concentrated, and it is easy to quench.
        5. The machining knife is too deep, that is, the surface roughness value is too large, and crack is easily generated.
