Optimalizace procesu tažení drátu / Optimization of the Wire Drawing Process

Kabilka, David January 2019 (has links)
The aim of work is to present and analyse assessment of the current state and at the same time the proposal of adjustments to the technology or parameters, the introduction of the wire into the drawing machine. The problem arises when the introduction of wire with a diameter of 14 mm from the material CK 67 to the drawbenches Schumag. If we introduce the wire into the drawing machines with two primary beams leads to a buckling of the wire and pack between the drawing die and the boot device. For the introduction of wire are used hydraulic boot collets, which are controlled semi-automatically. In connection with professional studies and on the basis of the calculation, simulation and practical experiment have been identified the conditions allowing the current method of deployment of wire to use.

Výroba pláště olejového filtru / The manufacturing of oil filter cover

Foltýn, Michal January 2010 (has links)
The diploma thesis was elaborated in the frame of engineering studies branch M-STG. This project is submitting design of technology production of oil filter cover from the deep drawing sheet iron 11 305.21. The size of production lot is 300 000 pcs/year. In relation to the shape of drawn part and the size of production was chosen the deep drawing technology and designed manufacturing process. For production was on the basis of realized engineering calculations chosen hydraulic deep drawing press and constructed drawing die. The drawing die is on the basis of a transfer conception and includes two blank holders and two ejectors.

Výroba tělesa olejového filtru / Manufacturing of oil filter

Prokop, Karel January 2013 (has links)
This thesis deals with the proposal of an oil filter body manufacture. The oil filter body is a rotational part made of DC02 deep drawing steel. With respect to the material, geometry and the size of the production, a deep drawing technology which does not consider wall thinning, was chosen. It was decided about necessity of five drawing operations. Suitable presses for a notching line and the very drawing were selected. Next part of the thesis is given to the design of the rolling tool construction. A drawing die for the first operation is described in details, including the controls and drawings. The economic part compares variants with the requirements of monthly production of 50 000, 180 000 and 350 000 pieces respectively. Due to the economic study, the production of 180 000 pieces per month was chosen.

Výroba součásti z plechu s využitím technologie hlubokého tažení / Production single parts from sheet metal with usage technology deep drawing

Jurča, Jan January 2009 (has links)
JURČA Jan: The manufacturing of sheet metal part by deep draw technology. Thesis of Master´s Studies, the 5th Year of Study, the School-year 2008/2009, The Institute of Manufacturing Technology, Department of Machining, FSI VUT Brno.The thesis deals with the project of manufacturing the part of the car body – the fifth door by deep draw technology. The material is zinc-coated sheet metal HX220YD EN 10292. Mechanical properties and suitability of the material are evaluated by mechanical tests. The structure of the material is evaluated by metalography scratch pattern. The analysis of draw process and manufacturability of the part is made by calculations and AutoForm software. The production line, necessary machinery and construction solution of draw tool for the manufacturing the part are determined. Last section deals with economical evaluation of the production.

Výroba olejové vany / The Production of the oil pan

Šupa, Jan January 2016 (has links)
The dissertation deals with a suggestion of the production of an oil pan into the car with a deep drawing. The part will be produced out of a deep drawed steel plate – class 11 305 (DC04). On the basis of a calculation and the study of the corresponding literature about the deep drawing a reverse drawing in a convention tools with a blank holder has been suggested. The part of the machine will be also an upper ejector for the fall of a sticking of a drawn part in the die. As a semi-product a blank has been chosen, which is burned out from the piece of plate with the dimension of 2500 x 12500 mm and thickness 1 mm with the help of the laser. The production quantity is 30 000 per one year. As a forming machine a universal hydraulic presser CTH 250 from the Czech company Žďas a.s. with the nominal power 2500 kN has been chosen.

Cykloturistika na Lipensku / Cycling-tourism in Lipno region

ŠTĚRBOVÁ, Kristina January 2010 (has links)
Subject diploma work was micro - region Lipensko, where was effected analyse of presumptions and development for cycle - tourism. Highlights was Lipenská main cycle track and her upward evaluation. Agent evaluation were designed stops on trace. Penthouses with sitting plus place for leant bikes. Stoppings: with informative or visual tables than mini fitness other possibility jogging section and calibration tachometer. After first analyse of cycle {--} tourism was making a marketing research, that has been drawn on set hypotheses. Hypotheses were given three and two of them were disproved. Negate conjectures were inspiration for a proposal project of the Lipenská cycle track. Final phase of the work is the proposal project and grant possibility of European union.
