Abstract
To improve the production quality and efficiency of the concave ring, a multi-pass stamping technology is used to replace the spinning technology to form the concave ring. First, the multi-pass stamping dies are designed according to the structural characteristics of the concave ring. Then, the process parameters are determined based on the bending conditions and the dimensional requirements of the concave ring. Next, the rationality of the designed stamping dies is verified by analyzing the stress and strain field of the multi-pass stamping concave ring. Finally, the stamping experiments are carried out. Experimental results show that the dimensional error of the concave ring formed by multi-pass stamping is less than 0.5%. The multi-pass stamping technology is feasible to form the concave ring. The reasonable design of the mold is the key factor to prevent defects in the workpiece. The concave ring formed by multi-pass stamping meets the industrial requirements.
Highlights
As a key part of an aero-engine, sheet metal casing parts are directly related to the overall performance of the aero-engine
From years of practice and experience, the spinning forming concave ring has been found to have the disadvantages of high technical requirements, a low production efficiency and poor forming quality [2]
Based on the characteristics of sheet metal bending and the limit value of bending, a set of multifield during the laser forming. These current studies focus on the establishment of a numerical model pass stamping dies for the forming of the concave ring is designed
Summary
As a key part of an aero-engine, sheet metal casing parts are directly related to the overall performance of the aero-engine. Mo [14] proposed an for prototyping sheet workpieces whileofmaintaining dimensional and without analytical model and finite element model to study the incremental air bending process Presented a finite element simulation of to a been developed for metal sheet to plane strain bending under tension. This model has been used temperature field during theon laser forming.moment. Based on the characteristics of sheet metal bending and the limit value of bending, a set of multifield during the laser forming These current studies focus on the establishment of a numerical model pass stamping dies for the forming of the concave ring is designed.
