Manufacturing of Trailer Connecting Joint
Vahala, Jiří ; Žák, Ladislav (referee) ; Řiháček, Jan (advisor)
The project elaborated design of technology production of the trailer connecting joint from the deep drawing sheet iron 11 320. Pursuant to of the literary pursuit a problem of the deep drawing and calculation was designed progressive tool concatenate four operations. The lower ejectors are using for ejecting components. The drawing instrument especially made of non-standardised components and it is designed for use on a hydraulic press CTH 250, with nominal tensile force 250 kN. Drawing punch and drawing die are produced from alloyed instrumental steel 19 436 heat-worked according to drawing documentation. The technical and economical evaluation was focused on the forming cost, which is 2 922 893 CZK in total.

Suitable lubricants for deep drawing of carbon steel plate
Poloch, Milan ; Císařová, Michaela (referee) ; Jopek, Miroslav (advisor)
The task of the diploma thesis is to design and manufacture a testing jig, which will then be used for experimental testing of lubricants for drawing stampings up to 4 mm thick. The drawn material is deep-drawn steel D04. Friction modeling between the traction edge and the retainer was used for a real simulation of the production process. The shaped traction edge was constructed on the basis of a real part. A total of 6 types of lubricants were tested, of which one lubricant in the form of a paste was selected as the reference. The other lubricants were then compared with the reference value of the measured maximum tensile force. The aim was to ensure a lubricant in a consistency other than paste. Of the oil lubricants we received, none of the lubricants approached the optimum values.

Production of the upper part of gasoline tank
Minář, Martin ; Staněk, Vojtěch (referee) ; Podaný, Kamil (advisor)
The thesis deals with the design of the upper part of the gas tank. Taking into account the shape and dimensions, the solution was chosen the most advantageous drawing technology without a thinning of 1 mm thick DC04 steel. The solution took account of the requirements of the contracting authority and selected the production for one operation. However, the simulation proved inappropriateness of the solution, so the procedure was modified to two operation proces. At the first stroke, a larger part of the body will be created, and in the other, a calibration of the cut-out dimensions will occur. For the first operation, the design of the tool kit, including drawing documentation for the CTH 250 press, was elaborated.

Suitable lubricants for deep drawing of steel
Hřebíček, Pavel ; Staněk, Vojtěch (referee) ; Lidmila, Zdeněk (advisor)
The aim of this work is experimental evaluation of suitability of lubricants for drawing of stainless steel 1.4301 at elevated temperature, which corresponds to temperature in real process. The lubricant testing method is based on friction modeling between the pull edge and the retainer, which corresponds to the real process. Therefore, the design of the test fixture also conformed to this model. The result of the work is a comparison of the suitability of every single lubricants with the reference lubricant used in ACO Industries. The best results were obtained with AT Kalorex 650 S lubricant, which contains environmentally harmful additives.

Production of wash basin drain grid
Běhounek, Martin ; Staněk, Vojtěch (referee) ; Podaný, Kamil (advisor)
This thesis deals with a draft on manufacturing a sink grill. It is a rotary component that is made of corrosion-resistant steel 17 240. Considering the material, the shape of the component and the size of the production lot of 100 000 pieces a year, the suggestion for manufacturing this component is a technique of a deep drawing with no wall thinning. It has been decided that the trimming will be done with a progressive blanking die and the deep drawing will be done with the use of pressing machine LKDA 315. One part of this thesis is a draft of a design of a tool for deep drawing enclosed in a drawing documentation. In the economic segment, there is a total of expenses for one product which is 9 CZK. Production becomes profitable after manufacturing 67 308 components.

Suitable lubricants for deep drawing of stainless steel
Doležal, Jan ; Chudík, Ivan (referee) ; Lidmila, Zdeněk (advisor)
This thesis solves problems of design and construction of testing equipment for testing lubricants for deep drawing and experimental evaluation of suitability of different types of lubricants for specified tests conditions. Most of all it is about finding environmentally friendly lubricant which would provide similar results as lubricants containing chlorine compounds when drawing a stainless austenitic Cr-Ni steel 1.4301. As for lubricants provided for testing by leading home and abroad manufacturers, the ATLAS 3374-140 from Quaker Chemical and the WISURA ZW 3356 from FUCHS, were evaluated as the most suitable environmentally friendly lubricants.

Production of drinker
Vašíček, Jan ; Dvořák, Milan (referee) ; Císařová, Michaela (advisor)
The diploma thesis of the master's study in the field of M2I-K presents a design of a hollow rotating part made of metal sheet with a tapering bottom. Deep drawing technology was chosen as the best suited option for production without thinning the wall. Stainless steel was chosen as a source material for production parts in compliance to ČSN 172 40. The drinker is produced by three drawing operations where each operation is performed separately on a standalone press CTH 250 developed by ŽĎAS a. s. A sheet measuring 1500 x 3000 x 1 mm with diameter 428 mm was evaluated as the most economically viable for production of a semi-finished product – rondel. For one year production produced in a series of annual volume 100,000 pieces.

The Manufacturing of Brake Disk cover by the Compound Tool
Kučera, Jiří ; Žák, Ladislav (referee) ; Peterková, Eva (advisor)
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.

Production of the shape cover
Žilka, Daniel ; Staněk, Vojtěch (referee) ; Podaný, Kamil (advisor)
This thesis deals with a project for production of output shaft cover for agricultural technique which is made of deep drawing steel DC04. On the basis of component geometry, material and contract volume (10000 pieces per year) the drawing technology without wall attenuation has been chosen. A production plan has been processed for this technique. Drawing will be realized within four operations in a modularly solved tool in double-acting hydraulic press Ždas CTH 250. A die design is a part of the thesis, the drawing tool for the first operation is described in detail. Within economic assessment a product price is counted and contract profitability is evaluated

Hudousek, Jiří ; Dvořák, Milan (referee) ; Císařová, Michaela (advisor)
HUDOUSEK Jiří: The Production Technology the fan cover. The project elaborated in frame of bachelor studies is submitting design of the fan cover production with sheet metal forming technology. Based on the literary pursuit a production process of the workpiece was designed when the blank is formed with deep drawing technology without thickness reduction (pure drawing) and subsequently completed by trimming to size, dimpling of the shell bottom, assembly holes punching and surface treated. Based on the calculation drawing in die with blankholder was designed for drawing operation and according to the force needed and tool size a hydraulic press ZH 160 (manufacturer PRESSHYDRAULIKA, s.r.o.) was selected. Material chosen for the production of workpiece is deep drawing steel sheet DC04 (ČSN EN 10130), production batch is 100 000 pcs. per year.
