Production of supporting plate
Filip, Jiří ; Řiháček, Jan (referee) ; Podaný, Kamil (advisor)
The thesis presents a proposal of technology for production of supporting plate, which is a top part of a service trolley, serving for manipulation with switch of high voltage. The supporting plate is manufactured of low carbon, deep drawing steel DX51D+ZM thickness 2 mm and quality according to EN 10346. Annual serie was set for 200 pieces. In evaluation of production possibilities were chosen technologies of punching and bending. There was designed unfolded shape of the sheet metal with dimensions 1068 x 900 mm and created cutting plan. As was found, from one metal board is possible to cut out 2 pieces of the supporting plate, while 70% of material use. In the next step, punching tools were chosen and manufacturing process was made. The highest achieved cutting force was 122,8 kN. The chosen machine is hydraulic CNC press TruPunch 5000. For bending there was created a bending plan, according to which bends will be made in thirteen steps. Used bending tools are punch OW209/S and two types of matrix EV005 + FWZ and EV006 + FWZ. Maximal achieved bending force is, according to the calculation, 259,8 kN. Bending operations will be made on CNC press TruBend 5130. In a technical and economical evaluation was determined cost for the material, which is 57 337,5 Kč.
