Manufacturing of part of door lock by compound tool

Academic thesis, drawn up within the framework of engineering studies, presents a proposal optimal production of garage door lock striker. The part is manufactured from steel sheet S275JR of 1.5 mm thickness. By the analysis of its possible methods of production, with regard to the required annual series of 500,000 pieces, was chosen technology of manufacturing the part in the compound tool by blanking and bending processes. For these technologies was designed solution of the compound tool and automatic production line with the eccentric crank press SMERAL S160, where is the compound tool fixed. The measure of financial performance of manufacturing the part is economical assessing. In the current state is investment return in the production of 179,186 pieces of the parts
