Concrete stirring vane die face design system and method based on springback compensation

Abstract

The invention provides a concrete mixing blade die-face design system and a method based on springback compensation, which comprises three modules, that is, a die-face automatic springback compensation design module based on numerical simulation, a die-face CAD reconstruction design module, and a die-face correction module based on reverse engineering, thus a concrete mixing blade die-face CAD-CAE-CAD integrated system based on the springback compensation is formed, and geometric errors produced after the blade being formed are required to satisfy design requirements on the level of numericalsimulation, thus reducing correction times; and the process of converting a CAE model after a virtual die repair into a CAD geometric model which can be designed and manufactured is finished, a digital model after the blade being actually pressed is acquired by utilizing a reverse engineering technology and then is compared with the required design shape of the blade, and springback deviation is obtained so as to be used for guiding the actual die repair process of the blade, thus correcting the residual springback deviation and further improving the precision of the springback compensation onthe basis of numerical simulation springback compensation.

Description

technical field [0001] The invention relates to a system and method for designing a mold surface of a concrete mixing blade based on springback compensation, and belongs to the technical field of mold surface design for stamping parts. Background technique [0002] At present, when stamping parts are stamped and formed, although reasonable process conditions are selected, such as blank holder force, die clearance, lubrication conditions, etc., and a reasonable die structure is adopted, due to the elastic recovery of the metal sheet after the external load is removed, the It will lead to the rebound deformation of the stamping parts, which will seriously affect the shape and dimension accuracy and product quality of the product. Therefore, under the premise of reasonable process conditions and mold structure, how to design the springback compensation of the mold surface and improve the product precision is an important content in the design and manufacture of stamping dies. ...
