一体化压铸切边整形技术的发展现状OA

Integrated die-casting technology has made significant progress in the automotive field by consolidating dozens or even hundreds of parts into a single cast component.However,the die-cast part has excessive waste that needs to be trimmed after demolding,and warping often occurs during the demolding process.Therefore,trimming and shaping(straightening)techniques in post-processing of die-cast parts have become critical to ensure the qualification rate of giga-cast parts.This paper reviews the trimming and shaping technologies,including the trimming techniques such as trimming dies,robotic arms,thermo-mechanical vibration,and high-speed sawing;the shaping techniques such as hot die straightening,point-to-point extrusion straightening,and in-die compensation correction;and the integrated trimming and shaping techniques,such as in-die compound trimming and shaping technologies,as well as trimming and shaping structures from the stamping field.Possible future development directions are put forward,aiming to provide a reference for the development of trimming and shaping technologies for integrated die-cast parts.
