Milling process of solid solution steel double gooseneck hinge

Abstract

The invention discloses a milling processing technology of a solid solution steel double-gooseneck hinge. A milling process that lug areas are processed, and then a base area is processed is adopted, the phenomenon that the base thickness is small, and consequently, the form and location tolerance of the double-gooseneck hinge is too large is avoided, through addition of a feeding path, the radial cutting depth of a tool at the round corner is reduced, and the method for controlling cutting force mutation is used for improving the form and location tolerance; and a ring cutting processing tool path and reasonable milling parameters are selected for meeting the processing coaxiality requirement of two lugs of a hinge workpiece, the processing efficiency of the double-gooseneck hinge is improved, and the assembling hole position precision requirement is met.

Description

technical field [0001] The invention belongs to the technical field of hinge processing, and in particular relates to a milling process of a solid solution steel double gooseneck hinge. Background technique [0002] In the fields of automobiles, ships, and furniture, hinges are important connecting parts, and their materials are usually made of high-strength steel. In order to save processing materials and improve efficiency, the hinges are generally formed by stamping or casting. In the field of aviation and aerospace, hinges are the connecting parts of aircraft doors and flaps. Affected by load, vibration, corrosion and other factors, the hinges of hatches and flaps are generally made of 15-5PH-solution steel. On the basis of comprehensive consideration of material performance, use requirements, manufacturing process and cost, the hinge of the upper lid of the aircraft is generally designed as a "double gooseneck" hinge. The thickness of the hinge base is thin, and part of...
