Abstract

The invention discloses a fuel cell electrode plate runner abrasive flow polishing device and method, curved surface parts with different radians are replaced according to different radian requirements, so that the sectional area of an abrasive flow runner is controlled, the wall surface pressure of abrasive flow on a fuel cell electrode plate is increased under the action of gaps between the curved surface parts and the abrasive flow runner, and the fuel cell electrode plate is polished. The grinding effect on the fuel cell polar plate is improved, the surface of the fuel cell polar plate and a flow channel of the fuel cell polar plate are continuously ground, the machining efficiency is further improved, and meanwhile the peripheral driving motor drives the disc-shaped clamp to rotate to achieve multi-directional machining of the fuel cell polar plate. And the runner of the fuel cell polar plate in different directions is further polished.

Description

technical field [0001] The invention belongs to the technical field of application of additive manufacturing to new energy, and in particular relates to a device and method for polishing a fuel cell electrode plate flow channel abrasive grain flow. Background technique [0002] In recent years, additive manufacturing technology has gradually become a research hotspot in the field of material forming and processing. Additive manufacturing technology can theoretically manufacture parts with any geometric shape, but due to the step effect and slag, the surface roughness of the parts increases. However, Traditional polishing methods: mechanical method and chemical method, but it is difficult to achieve effective finishing for some runner surfaces with complex trends. In this regard, manual grinding and polishing methods are generally used, but the efficiency of manual grinding and polishing is low and the consistency is poor, general tools are difficult to enter, and some slag a...
