Strengthening technology
Crankshaft intermediate frequency induction hardening
The intermediate frequency induction hardening of the crankshaft will adopt a microcomputer-controlled closed-loop intermediate frequency induction heating device, which has the characteristics of high efficiency, stable quality, and controllable operation.
Crankshaft nitrocarburizing
For mass-produced crankshafts, in order to improve product quality, a microcomputer-controlled nitrogen-based atmosphere gas nitrocarburizing production line will be used in the future. The nitrogen-based atmosphere gas nitrocarburizing production line is composed of a front cleaning machine, a preheating furnace, a nitrocarburizing furnace, a cooling oil tank, a post cleaning machine, a control system, and a gas production and distribution system.
Crankshaft surface strengthening technology
Nodular cast iron crankshaft fillet rolling strengthening will be widely used in crankshaft machining. In addition, compound strengthening processes such as fillet rolling strengthening and journal surface quenching will also be widely used in crankshaft machining. Forged steel crankshaft strengthening methods will be more The ground adopts the shaft journal and fillet quenching treatment.
