Description
Summary:For strong vibration, high temperature and dust in the forging site, a displacement detection system based on eddy current sensor is proposed to monitor the size of forgings online in this paper. Equidistant grooves are machined in the vertical direction on the side of hammerhead and the eddy current sensor probe is installed opposite the grooves in the rack. The hammerhead displacement can be obtained with output voltage signal according to hammerhead moving process. The feasibility of the proposed system is determined based on the magnetic field characteristics analysis of groove specimen surface using Ansoft software. The mathematical model of the displacement measurement is established through experiments on the processed metal plate. Experimental results show that the novel displacement detection system is feasible and accurate position of forging hammerhead can be obtained.
