Šimka, Radek ; Podaný, Kamil (referee) ; Řiháček, Jan (advisor)
The diploma thesis is focused on the design of a suitable production technology for a bottle cap opener, which is made of stainless steel X12CTNi18–8. The production series is set at 250,000 pieces a year. A sheet roll with a thickness of 1 mm is selected as a semi-finished product. After evaluating the possible production variants, the most suitable technology is the production in a combined process tool. The part is made in five steps, involving shearing and bending technology. A literature review is prepared for the chosen production technologies and then the necessary technological, construction and control calculations are done. The press PE45M from Vaptech company is chosen as the facing machine for the production of the opener, which keeps all the necessary requirements. The insert of the sheet roll into the machine is going to be done with the help of unwinding, straightening and feeding devices.

Manufacturing of a shift fork of a motorcycle
Vysloužil, Oldřich ; Štroner, Marek (referee) ; Peterková, Eva (advisor)
This master´s thesis deals with the design of production technology of the shift fork in the gear box in a Jawa motorcycle. The 16MnCr5 (1.7131) basic material, with its thickness of 2.5 mm, was chosen for production of the bent sheet metal part, which is going to be subsequently heat treated. As the most suitable production method for the given series of 25,000 pcs. per year, was selected production method in the compound progressive tool, which combines shearing and bending. To select forming technologies, a short study of literature was made, which was supplemented by determination of the production process. The calculations, which were needed to verify the technological conditions, were made for the selected the manufacturing process of the part and also to select the machine. An APA-60 type eccentric press was chosen according to the determined total forming force. The machine is supplemented with a device that nebale production automation, which is an unwinding stand for a scroll metal sheet and a step feeder. At the end, a description and visualization of the tool is presented.

Manufacture of car lock components
Andris, Tomáš ; Císařová, Michaela (referee) ; Lidmila, Zdeněk (advisor)
The thesis is focused on the proposal of manufacturing technology of the opening lever for a car latch. The lever is made of S355MC sheet metal with thickness 2 mm, production series is set for 400 000 pieces per year, which includes 200 000 pieces of right and 200 000 pieces of left version. After considering several production methods, combined progressive die was chosen. The part is made in ten steps, which include shearing and bending. Necessary technological, design and safety calculations were also made. For production was chosen eccentric press S160 made by ŠMERAL company. Surface protection of the part will be provided by galvanizing. At the end of the thesis a technical and economical evaluation is provided. The final price of one piece of lever is calculated to 13,3 Kč, economical turning point when production become profitable was calculated to 156 339 pieces.

Manufacturing of a Cable Holder
Šimka, Radek ; Žák, Ladislav (referee) ; Řiháček, Jan (advisor)
The bachelor’s thesis proposes a design for the production technology of the cabling holder, situated in the outdoor part of the air conditioner. This product is made of steel sheet DC01 with a thickness of 1 mm. The production of this holder is set to be 200 000 pieces per year. A progressive die tool was selected as the most suitable type of production technology, based on a literature study of various production technologies. This enables to combine cutting and bending of steel sheets with the use of one tool device. Manufacture will be performed using a mechanical eccentric press LEN 63 C. All the necessary requirements of this device are satisfactory for the production.

Manufacturing of backstop
Toufar, Jan ; Řiháček, Jan (referee) ; Podaný, Kamil (advisor)
Thesis solves the design of manufacturing technology of steel backstop – the part made by shearing and bending. The component will be made from a rolled steel coil of the DC01+ZE25/25-A-P-C material with the thickness of 1 mm. The batch size is determined 200 000 parts per year. At base of choosen process and calculations is designed progressive die for shearing and bending. Shearing punches, punching dies, bending punch and dies are made from steel 19 436. Die is made for eccentric press LENR 25-A with forming force 250 kN.

Production of cover plate
Rubáš, Petr ; Lidmila, Zdeněk (referee) ; Podaný, Kamil (advisor)
The thesis is focused on the proposal design of the technology of the production of the cover plate of the lock, which together with other parts forms part of the fifth door of the passenger car. The cover is made of 2 mm metal sheet and includes a number of bends, embosses, cuts and trimmed holes. Based on production requirements and a series size of 1,200,000 pieces over 3 years, the production using a progressive composite tool was chosen. The part will be made in eleven steps composing of cutting, stamping, bending and edging. Micro-alloyed structural steel S355MC was chosen as the most suitable material. The part will be produced on the press KSTU 5000-30-7G RKM from the company ANDRITZ Metals and the price of the product is 14,33 CZK.

Manufacturing of body latch
Vybíral, Ondřej ; Šlais, Miroslav (referee) ; Podaný, Kamil (advisor)
The work proposes production of a bend part made of 2 mm thick steel sheet 11 320 with 50 000 parts made per year. Based on the literary study of this problematic the production was chosen to be made with combined processing tool for bending and shearing. The tool is designed to do two shearing and one bending operation. Due to the enclosed shape of the bend the part is ejected from the side perpendicularly to the direction of motion of the sheet belt. The mechanical press S160 with nominal forming force of 1600 kN was chosen for the production. Shearing punches and punching dies are made of tool steel 19 422. Bending punch and dies are made of carbon steel 19 312. Price per unit was set to be 12,61 Kč. Break even point was counted to 34 849 parts.
