Abstract

In engineering practice, there are cases where it is necessary to design a suitable technology for the production of a small number of pieces of parts to achieve a minimum price of one piece of a manufactured part. The paper describes the development of a low-cost drawing tool for the production of a small number of pieces of cover stampings from 2 mm thick sheet metal from DC04 steel. The most economically advantageous solution was to use a press brake, in the working part of which a simple drawing tool is clamped. The shape of the blank was designed for the cover stamping. The simulation of the drawing process using the CAE program using FEM made it possible to analyze the drawability of the cover stamping using the forming limit diagram of the used sheet and also to analyze the places with the greatest thinning and the risk of cracking. A designed low-cost drawing tool was made. The production of test blanks for drawing the cover stamping was performed by laser beam cutting. The subsequent drawing of test pieces of stampings verified the applicability of the proposed low-cost drawing tool on a press brake. The possibility of drawing intricate shape stampings using a drawing tool attached to the working part of the press brake was verified.
