Abstract

The invention relates to a detection method and device for a workpiece forming process. The detection method comprises the following steps of calibrating a relative position relationship among detection data of multiple pieces of non-contact detection equipment; establishing a splicing transformation relationship among the detection data of the non-contact detection equipment; obtaining forming contour detection data of a to-be-detected workpiece; and splicing the contour data in the workpiece forming process to form complete contour data of the to-be-detected workpiece. According to the detection method and the device provided by the embodiment, the workpiece forming process is detected in real time by applying multiple pieces of non-contact detection equipment, the spatial position relationship corresponding to the detection data is calibrated, so that the detection data can be spliced to the same coordinate system to form complete workpiece contour data, high-precision on-machine contour detection in the workpiece forming process is achieved, defects in the workpiece forming process can be found in time, the production cost is reduced, and the workpiece quality is improved.

Description

technical field [0001] The invention belongs to the technical field of detection, and in particular relates to a detection method and device used in a workpiece forming process. Background technique [0002] In recent years, with the continuous development of technology, the manufacturing industry has also begun to develop in the direction of automation and intelligence. In this process, different fields put forward new requirements for detection technology. Taking the rolling flexible forming workpiece represented by the metal sealing ring as an example to illustrate: as a new type of sealing structure, it has the advantages of good high vibration followability, high vibration absorption capacity and good wear resistance. It is used for the sealing of key parts such as aero-engine turbines and casings. The forming quality of the metal sealing ring section is an important factor to ensure the performance of the metal sealing ring, but its cross-sectional shape is complex a...
