This paper represents results of student project. The main goal of this work was to redesign and construct hand controlled machine to bend gutter hooks. Hand bender for gutters hooks is used by plumbers’ shops. Redesign of the hand bender is processed with several improvements. The whole process of construction is described in this work. From the introduction to the bending technology, choosing the most optimal construction variant of the other mentioned benders, to final dimensioning and FEA strength analysis. The base load is deduced from forming technology theory. FEA is used to evaluate results of prior dimensioning and to evaluate proper design.
