Riveting Technical requirements: appearance. Riveting machine surface should not have raised pattern is not specified, the depressions and rough, parts and components edge joints should be neat, symmetrical, there should be no significant dislocation. Painting quality riveting machines comply with the relevant standards. Countersunk screws should not protrude from the surface of the part of Anhui fast hydraulic riveting machine, fixed pin should be slightly protruding from the surface of the part, the end should be protruding bolt nut Shanxi fast hydraulic riveting machine, but should not be too long and uneven projection. Hole-riveting method: the production of rivet holes Zhejiang rapid hydraulic riveting machine, the drill diameter must be selected. Due to the presence tolerance normal rivet diameter drill diameter must be slightly larger than the rivet diameter, can be successfully put as riveting rivet holes. Hole-ordinary riveting method that is generally two punching and drilling.
