In order to meet the requirements of a company in Hebei province,a kind of band saw blade automatic shaping equipment was designed,which could be used to shape the cross-section of the band saw blade and make it into the needed cross-sectional shape in the production process.The equipment was mainly composed of four parts,namely the radial movement part,the deformation detection part,the force part and the automatic control system.The equipment could automatically control the synchronous movement of the whole band saw blade according to the detection result of the equipment in the processing of the band saw blade cross-section to avoid the occurrence of the distortion and deformation of the band saw blade caused by the uneven force during the process,realizing band saw blade cross-sectional shape precise processing,improving processing efficiency and reducing labor intensity.
