The Design of Bending Parts Compound Die

Abstract

Through analyzing U type bending parts that has bottom-holes, a suitable Compound die that can complete 4 procedures - lancing, bending , punching and be cut off at in the same forming-position was synchronously designed. The die working process and the main points of the design are introduced here. Production testing confirmed that there were different levels of improvements in the product quality, production efficiency and economic efficiency. In order to meet the design and development requirement of the die, the proportion of the compound and progressive dies in the dies production has been increased in consideration of the structure and production costs of the die.

Design and Analysis of Compound Die to Produce L-Shape Product with 3 Holes

“…Recent advancements in the field of compound die design have demonstrated significant improvements in both efficiency and cost-effectiveness. A notable study successfully integrated compound and progressive dies within a single framework for the fabrication of U-shaped components, resulting in marked improvements in both the quality and efficiency of production [2]. Additionally, another research initiative led to the development of a compound die that effectively combines cutting, drawing, and trimming operations, thereby reducing overall costs, and enhancing operational efficiency [3].…”
