Abstract

The invention provides a method for quickly detecting the thickness of the lower surface of a blade in a high-temperature thermal state and aims at solving the problem of low detection efficiency of a traditional method. The method is characterized in that an inner cambered surface floating detection sample plate and a back cambered surface floating detection sample plate which are matched with the inner cambered surface and the back cambered surface of the blade to be detected are respectively manufactured according to the shape of the blade to be detected, detection regional holes are respectively and correspondingly cut and formed in the inner cambered surface floating detection sample plate and the back cambered surface floating detection sample plate according to the position of the thickness of the surface to be detected on the blade to be detected, then the inner cambered surface floating detection sample plate and the back cambered surface floating detection sample plate tightly adhere to the inner cambered surface and the back cambered surface of the blade to be detected, and then a pair of outside calipers is utilized to detect the thickness of a blade forge piece between the detection regional holes in the inner cambered surface floating detection sample plate and the back cambered surface floating detection sample plate of the blade to be detected.

Description

technical field [0001] The invention relates to the technical field of thermal processing and forging, in particular to a method for quickly detecting the profile thickness dimension of a blade in a high-temperature thermal state. Background technique [0002] In the process of mass production of products, in order to test the stability of process control, sampling the maximum thickness of the characteristic section of the blade is a very effective control method, but the final forging temperature of the blade after hot die forging is generally higher than 850 ° C, at this time under high temperature If you want to accurately measure the maximum thickness dimension of different height sections of the blade surface, you must mark the height of the blade section on the special blade detection frame and sample plate after the blade is cooled to room temperature, and use the external caliper to detect it. From the final forging temperature Cooling to room temperature generally t...
