Problems solved by technology

[0004] In order to solve the technical problem that the existing processing methods cannot better meet the requirements of the coaxiality and position of the lugs, the present invention proposes a solid solution steel double gooseneck hinge milling process, which can effectively ensure the coaxiality of the lugs. Accuracy requirements and positional requirements at the limit groove, improve the processing efficiency of the "double gooseneck" hinge, and meet the assembly hole accuracy requirements

Embodiment Construction

[0029] Below in conjunction with specific embodiment, the present invention will be further described:

[0030] See attached figure 1 to attach Figure 7 , a solid solution steel double gooseneck hinge milling process, comprising the following steps:

[0031] Step 1: blanking, heat treatment, heating to 552 degrees Celsius, after heating for 4 hours, air cooling.

[0032] as attached figure 1 As shown, blanking, the tolerance of length and width is 0~±5mm, and the precipitation hardening stainless steel is heat treated.

[0033] Step 2: Mill the hexagonal blank, drill and ream the technological hole, and accurately clamp.

[0034] as attached figure 2 As shown, the blank is milled hexagonally to ensure that the flatness of the two major planes is 0.1, and that the parallelism with the bottom surface of the base is 0.1.

[0035] as attached figure 2 As shown, drill and ream the process hole, and ensure the verticality with the ground 0.05; precise clamping.

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...
