The thesis focuses on the production concept of component Cage ECR 10 12, which is used as assembly element together with a nut during the bus production. Sheet metal part is made from 11 321 steel 1,5 mm thick in production 10 000 parts per year. Technology of production in progressive tool was selected based on literature study. Progressive tool combines technology of shearing and bending. Tool was designed after the technological calculations. Forming machine was selected after the stamping force calculation. Eccentric press LEN 63 C with 630 kN forming force was selected for production.

The diploma thesis presents technology production design of a data projector bracket made of 2 mm thickness 11 321 steel plate. Considering the large production quantity and maximum tolerable deviations, a progressive die tool along with cutting and bending was chosen as the optimal solution for this type of production, based on a variant solution. Technological aspects were assessed, the production process was established, and technological and control calculations were performed. According to the total forming force of 2 000 kN, the LDC 250 mechanical press with a nominal force of 2 500 kN, manufactured in Šmeral Brno a.s., was chosen to meet the production requirements. The chosen material in a form of metal sheet coils will be supplied to the machine by a feeding device. The article will be manufactured in six steps. Based on technical-economic evaluation, the final price of a single piece in a series of 250 000 pieces per year was set at 30,80 Kč.

This master’s thesis is focused on the design of the technology to produce a part of the TV bracket. The part is made of steel sheet with a thickness of 2.5 mm. The structural steel S235JR was chosen as the most suitable material with following powder coating. From the possible variants, the production by progressive forming tool was chosen with respect to production requirements and a series size of 30 000 pieces by year. The part will be made in seven steps in designed tool and the total required force is 1013 kN. The production will take place on a mechanical press PCK12 from Bliss-Bret with a maximum force of 1250 kN. The final price of the part is 39.4 Kč.

This paper presents a design of the production process for the clamping nut by cold extrusion. The nut, which is made of material ČSN 12 050, is used to clamp the injection nozzle to the injection system. Subsequently different variants of production were processed, from which the variant B was chosen. For slug a rod with diameter size of 24 mm with toleration f9 made by the company Ferona a. s was chosen. Calculations of process parameters were made for this variant. Based on the parameters the automatic forming machine TPD 630 with nominal force of 6 000 kN was chosen. For the selected machine, operational tools were designed for each forming operation, whose geometry is shown in the drawing documentation. Based on the technical and economical evaluation, the final price of the formed part was set at CZK 18,48.

The elaborate project present suggestion of technology of produktion pressed piece from engineering steel 11 375 in framework of engineering studies in branch 2307. Production series do 100 000 pieces. By virtue of literary study of surface forming work and calculation was devised procedural tool. The tool is solved by form usual rack fix on crank press LEN 40 (producer TOMA Industries Trnava), with traction 400 kN. Punch and stamping die are made from tool steel 19 436.3 (POLDI 2002) along graphic documentation.

SKLENÁŘ Luděk: Bulk forming technology of grooved charge. The project prepared as part of the Master-degree studies in the Manufacturing Technology and Management in Industry, concerns the technology design for manufacturing a grooved charge by cold bulk forming. Grade 12 040.3 (CSN) steel was used as the initial material. For the batch of 50,000 pieces per year are proposed three alternatives. The chosen option No. 1 is made of technology and tensile strength calculations for metal forming operations: upsetting, backwards extrusion, forward extrusion and calibrating. The grooved charge production is designed for two forming processes that will be realised at the Colombo press Agostino, which is part of the machinery park company Metaldyne Oslavany. The extruding dies for the manufacture are made of tool steel 19 655 and tool steel 19 830 is designed for extruding punches.

Slider is a part of turn restrictor mechanism designed by company TOKOZ a.s. It is a part with complicated form and small dimensions from material DC04 (equivalent according to Czech standard ČSN 11 305.21). As the most suitable option for part manufacturing was chosen cutting and bending in progressive die. A design of forming layout with 11 stations was made and considering the outcomes of related calculations preliminarily selected presses LEXN 100 and Kaiser KSTU 1600. Subsequently was designed one row progressive die. Based on this designs were made few variants of part price calculations according to TOKOZ company customs. According to price calculation outcomes was as the most suitable selected press Kaiser KSTU 1600.

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.

The diploma thesis deal with the proposal of connector manufacturing from bronze sheet CuSn6, thickness 1.5mm in production volume of 1.600.000 parts per year. From considered manufacturing variants there was chosen shearing and forming technology of thread in the progressive stamping die. For part production was selected pressing machine Bruderer 1250 with nominal pressing force 1250 kN from company E. Bruderer Maschinenfabrik AG. In the economical evaluation there were determined expenses 21.6 Kč per one piece including demanded profit. The turning point was calculated at production of 165.522 parts.

This project is conceived within the master's degree in engineering technology and industry management (M2I-K Engineering) technology by design of the brake disc cover in compound tool, with year production 500 000 pcs. The material is deep-drawn sheet metal 11 305.21, 1 mm thickness. It is based on the literature studies about forming and calculation was suggested several variants of the present components. The proposed tool is clamped in the crank press LDC 400 firm Šmeral with a nominal force of 4000 kN. The functional parts are made from steel 19 573. The proposed technology of the deep drawing was verified by using simulation program AutoForm.
