Abstract

The invention discloses a method for obtaining an electromagnetic forming coil capable of realizing uniform deformation of plates. The method comprises the following steps: acquiring a deformation amount specific to flat plate blanks formed by means of repeated electromagnetic forming, and selecting matched electromagnetic forming coils according to the deformation amount; acquiring the skin depths of the electromagnetic forming coils according to the electrical conductivities of plates to be formed, the discharge frequency of electromagnetic equipment and vacuum permeability; acquiring the parameter ranges of the electromagnetic forming coils according to the skin depths; selecting the structural parameters of multiple groups of electromagnetic forming coils within the parameter range by adopting a control variable method; performing deformation simulation on the multiple groups of electromagnetic forming coils and matched plates respectively, selecting an optimal structural parameter according to plate deformation results, and obtaining the electromagnetic forming coil according to the optimal structural parameter. By adopting the electromagnetic forming coil provided by the invention, metal plates which are deformed uniformly can be obtained, and further forming of the plates is facilitated.

Description

technical field [0001] The invention belongs to the technical field of part forming and manufacturing, and more specifically relates to an electromagnetic forming coil acquisition method for uniformly deforming a sheet material. Background technique [0002] Electromagnetic forming is a high-speed plastic processing method, which uses electromagnetic force to deform metal materials in an instant. This high speed is very beneficial to forming, which can improve formability, improve stress distribution, reduce wrinkling, effectively control springback, and improve the ability of local pressing and embossing. At present, electromagnetic forming is mainly used in the forming of small aluminum alloy thin plate parts. There are great difficulties in the forming of large aluminum alloy plate parts. It is electromagnetic forming to realize the electromagnetic forming of aluminum alloy large plate parts and improve their forming quality and performance. Necessary conditions for form...
