Production concept of wall mounting bracket

The thesis deals with the solution of the design of the production of a holder for compact switchgear cabinets. The production series was set at 400,000 pcs/year. The part will be made from DC01 steel with a thickness of 2 mm. The equivalent is steel 11 321. Of the possible production variants, the technology of the progressive forming tool was chosen. The arrangement of the blank on the sheet metal strip is a two-row layout, where two components will be produced at once. A coil of sheet metal with exact dimensions was chosen as the semifinished product. The material utilization coefficient is 80.18 %. The part is manufactured in 8 steps and the necessary technological and structural calculations were made for this variant. The total force to produce the part is 1,240 kN. The machine selected is an eccentric crank press from the company Formetal s.r.o., with the designation CC 160. After the actual production, the components will still be galvanized
