Tool and method for correcting the head of a flame cylinder

Abstract

The invention discloses a flame tube head calibration tool and method. A spoiler is arranged inside the flame tube head, and the calibration tool includes a base and a calibration head whose tail is connected to the base; the calibration head and the blades of the spoiler have the same bending angle, The thickness of the correction head is smaller than the blade clearance of the spoiler. The method includes selecting a correction tool that matches the deformation part, passing the correction head of the selected correction tool through the blade gap of the spoiler and attaching it to the deformation part of the head of the flame tube, and then using a bakelite hammer or moving the head of the flame tube to correct the deformed parts. The correction tool of the present invention can pass through the blades of the flame tube spoiler to reach the deformed part of the flame tube head, thereby effectively eliminating the deformation of the flame tube head, effectively correcting the deformation of the flame tube head, and effectively avoiding the deformation of the flame tube head. The situation where the flame cylinder was scrapped due to deformation. At the same time, the calibration tool of the present invention has the advantages of compact structure, low manufacturing cost, convenient use and maintenance, simple operation and high processing efficiency.

Description

technical field [0001] The invention belongs to the field of flame cylinder processing, and relates to a flame cylinder head correction tool and method. Background technique [0002] In the design of modern aero-engine combustion chamber components, the combustion chamber is required to be small in size, light in weight, and short in length, and the reference velocity of the airflow in the combustion chamber is relatively high, resulting in a very short time for fuel and air to be mixed and combusted. In order to fully consider the problem of full combustion within a certain period of time, a spoiler is usually installed at the head of the flame tube. After the airflow entering the combustion chamber passes through the spoiler, its flow state changes, and a recirculation zone will be formed behind the head of the flame tube. The spoiler is an important part of the combustion chamber, and its working performance directly affects the combustion Comprehensive performance of th...

Problems solved by technology

[0003] The existing flame cylinder has a very complicated process from sub-part processing to finished product storage, with a total of more than 160 processes; the processing cycle is very long, about 3 months; at the same time, the first section of the flame cylinder head is a sheet metal formed part, and the material thickness Very thin, and at the upper end of the flame tube, local deformation often occurs during processing

[0004] The technicians found in actual work that after the head of the flame tube is processed to the finished product, due to the limitation of the structure of the spoiler blades, there is no existing calibration tool that can effectively reach the deformed part of the head of the flame tube, resulting in the deformation of the head of the flame tube. The deformation cannot be effectively corrected and eliminated, resulting in the scrapping of the flame tube
