Manufacturing of the electric motor cover
Kolář, Zdeněk ; Svoboda, Petr (referee) ; Císařová, Michaela (advisor)
The bachelor 's thesis focuses on the design of the production of an electric motoro cover made prom low-carbon steel 11 305 with a thicnkess of 1,5 mm. For an annual production series of 100 000 pieces per year, the technology of deep drawing without wall thinning has been selected. In the practical part, it was found that the cover body can be produced in a single drawing operation. The blank diameter, increased by the trimming allowance, is 212 mm, which will be produced by cutting from coils with a width of 222 mm and a outer diameter of 1200 mm. Total fore of 249,18 kN includes the drawing component, holder and ejector. Production is carried out on the CUPJ 63 DEU hydraulic press from HŠV Polička, equipped with a lower hydraulic device. Deep drawing die is designed for the machine, which enables the production of the cover body in one drawing operation. Design is supplemented with a detailed assembly procedure. Lubricant MORLAUB KFP 61 V is used for optimal process condition.

Production of the electric motor cover
Havlíček, Lukáš ; Staněk, Vojtěch (referee) ; Podaný, Kamil (advisor)
The present thesis solves a design of electric motor cover; specifically it deals with manufacture of cover body. A drawing is of simple flange-free cylindrical shape made of deep-drawn 11 305 steel sheet. With respect to the given shape of the component, material and annual series of 25,000 pieces, the most suitable technology selected was the method of deep drawing without thinning the wall by means of conventional tools. The process of deep drawing will be performed using a single-acting deep drawing tool supplemented with technical documentation. This tool is designated for the hydraulic press ZH 40 with a total drawing force of 400 kN. In the technical-economic part, the price of one product (respecting the indirect costs) was calculated for 42 CZK.
