Measuring tool for measuring aluminum alloy ring and measuring method

Abstract

The invention discloses a measuring tool for measuring an aluminum alloy ring and a measuring method, wherein the measuring tool comprises a hot-state measuring long ruler and a cold-state measuring template, the main body of the hot-state measuring long ruler is long angle steel, one end of which is provided with a locating pin which is vertical to the angle steel, and the other end of the angle steel which is provided with the locating pin is fixed with a one-meter steel ruler. The whole long ruler is transmitted according to a national standard length value transmission system by adopting a direct-measuring method, and the error of the long ruler is calibrated. The cold-state measuring template comprises a square framework and an aluminum alloy standard round ring which is fixed on the framework. By using the two methods, the problems of hot-state measurement and cold-state measurement of Phi 5000mm-grade aluminum alloy forging parts are solved, and conditions are created for rapidly and accurately determining the ring size, the form and position tolerance and the allowance, thus solving the problems that are badly in need of solution in production.

Description

technical field [0001] The invention relates to the problem of rapid and accurate measurement of parameters such as dimensions, shape and position tolerances, margins and the like during thermal processing and cold state of large aluminum alloy rings, and belongs to the field of aluminum alloy processing. Background technique [0002] At present, the rapid and accurate measurement of aluminum alloy rings in a hot state has not been well resolved, because the traditional steel ruler is only 1 meter long at most, and the steel tape is 6-7 meters long, but due to Its rigidity is too poor, and it is difficult to measure quickly and accurately when the ring is in a hot state; in addition, the forging temperature range of aluminum alloy is very narrow, only 100°C for 2219 alloy, so it is required to achieve rapid measurement in the hot state, and the ring is cold in the cold state. In this state, it is necessary to determine the specific size, shape and position tolerance, and mar...

[0002] At present, the rapid and accurate measurement of aluminum alloy rings in a hot state has not been well resolved, because the traditional steel ruler is only 1 meter long at most, and the steel tape is 6-7 meters long, but due to Its rigidity is too poor, and it is difficult to measure quickly and accurately when the ring is in a hot state; in addition, the forging temperature range of aluminum alloy is very narrow, only 100°C for 2219 alloy, so it is required to achieve rapid measurement in the hot state, and the ring is cold in the cold state. In this state, it is necessary to determine the specific size, shape and position tolerance, and margin of the ring, which is also a question that must be answered in the process of acceptance of the heat treatment of the ring.
