The invention provides a manufacturing method of a template with a specially-shaped cross section. The manufacturing method comprises the following steps of: drawing a cross-section diagram of the specially-shaped cross section, and then drawing a view of a steel plate on the cross-section diagram in an overlapped manner; measuring the detailed dimensions of parts where the view of the steel plate is not overlapped with the cross-section diagram; marking out the positions of coordinate points of the measured dimensions on the view of the steel plate; correspondingly connecting the marked coordinate points on the entity of the steel plate according to the shape of the cross-section diagram, so that the shape of the specially-shaped cross section formed by connecting the coordinate points is identical with that of the cross-section diagram; and cutting the specially-shaped cross section formed by connecting on the entity of the steel plate by using an acetylene gun. According to the manufacturing method provided by the invention, the manufacturing precision of the template with the specially-shaped cross section can be improved, so that the manufactured template is closer to the design requirements, and the purpose of saving a formwork and caulking time is achieved.

Manufacturing method of template with specially-shaped cross section

The invention provides a fabrication method of a straight bevel gear shaping processing template, and relates to improvement of a fabrication method of a straight bevel gear shaping processing template. The supporting template obtained by the fabrication method can meet different gear parameter requirements and has small gear shaping errors. The fabrication method comprises the following steps: calculating a horizontal coordinate and a longitudinal coordinate of a curve of a template for double-tool gear tooth surface machining according to formulas as follows: Xi=xi+etaixR and Yi=yi+etaiyR, or calculating a horizontal coordinate and a longitudinal coordinate of a curve of a template for single-tool upper-lower gear tooth surface machining according to formulas as follows: Xi=xi+etaixR, Yi=yi+etaiyR, Xi*=Xi-etaixR and Yi*=-yi+etaiyR; and making cross sections of the curve of the template to process a curve according to coordinate points Xi and Yi or coordinate points Xi, Yi, Xi* and Yi*.
