Simulation of thin-sheet metal blanking and punching by elastic mediums

Abstract

The paper describes the processes of thin-sheet workpiece blanking/punching using an elastic tool in an open and closed container. Finite element models are constructed, which describe the process of separation of the workpiece by an elastic workplace tool. A comparative analysis of the geometrical dimensions of the workpieces obtained as a result of theoretical and experimental studies was carried out.

Modeling of continuous molding process with elsatic composite working tool

“…To describe the behavior of a hyperelastic material, the two-parameter Mooney-Rivlin model was adopted, which accurately describes the behavior of a material under strains not exceeding 30-50% [1][2][3][4][5][6][7][8][9][10].…”

“…As an alternative, instead of a rigid working tool, a cheap elastic tool based on elastomers is used [1][2][3][4][5][6][7][8][9][10]. The main such material is polyurethane SKU-7L.…”

The Effect of Aluminum Profile Thickness and Type of Lubricant on Punch Force

“…Thin sheet metal blanking and punching products with elastic media are of low quality, due to the large geometric distortion of the separate parts and of the part in the cut zone, which is why these methods can be recommended for the manufacture of noncritical parts that do not require high accuracy [11]. The blanking and punching methods of thin sheet metal with elastic media can be used for the production of noncritical products that do not require precision.…”
