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.

Manufacturing of fireplace insert exchanger
Běhounek, Martin ; Staněk, Vojtěch (referee) ; Podaný, Kamil (advisor)
This master’s thesis deals with a proposal of production technology of a fireplace insert. Based on various solutions of production and documented calculations, charring has been elected as the most optimal technology. According to the requirements of thermal resistance and weldability the component will be made of boiler metal plate 11 416. Based on checking and technological calculations process of charring on press BAYKAL APHS 3110x180 has been proposed with the nominal power of 180 tons. The verification of bends was realized using computer simulations. Bending tools are made of steel 12 050. A technical-economic evaluation is also part of this master’s thesis.

The reinforcement door locking manufacturing by compound tool
Drápala, Miroslav ; Staněk, Vojtěch (referee) ; Peterková, Eva (advisor)
The submitted project was created in the engineering studies of M-STG Machinery technologies and it is focused on problematics of production of reinforcement door locking. Component will be manufactured by cutting and bending technologies and used material is aluminium alloy EN AW-3103. As a manufacturing stock is used roll of sheet. Manufacturing series is 400 000 pieces a year. Literary study was created according to the mentioned technologies. After the control calculation was proccesed, the compound tool was designed. As a working machine was selected accentric press SMERAL LE 250/40, where the compound tool will be clamped.

Suitable lubricants for deep drawing of stainless steel
Mück, Jonáš ; Staněk, Vojtěch (referee) ; Lidmila, Zdeněk (advisor)
The intention of this thesis is the experimental evaluation of different lubricants and their suitability for deep drawing of stainless steel 1.4404. The testing method is based on the friction model at the point of drawing edge and retainers. This model corresponds with a structure of testing fixture. The suitability of every single lubricant for this application has been determined by comparison of the output, which is dependance of the strength on the track with the reference results. The testing has been performed on many different samples provided by various manufacturers. The best result was measured with the oil Kalorex AT 650 S, manufactured by AT Oil, which belongs to the group of environmentally harmful lubricants. Based on the results of this experiment we can conclude that chlorine content significantly increases the lubrication capability especially under high pressure. The modification of preparation geometry which presumes the elimination of certain undesirable disturbances accompnaying the experiemnt has been also proposed.

Optimization of production process of drain
Staněk, Vojtěch ; Chudík, Ivan (referee) ; Podaný, Kamil (advisor)
The project looks for a solution to optimalization of rotational deep drawn part with flange production. It deals with sewerage drain, which is produced by conventional tool to two deep drawing operations. The used material is austenitic Cr-Ni stainless steel 1.4301. Suitability of this material for deep drawing operations was considered by means of the tensile test and the Erichsen test. On the bases of these results, serializability of production and theoretic relationships for determination of number of deep drawing operations, it was decided upon one operation serial production, by conventional tool without attenuation thickness of sheet. Production will take place on hydraulic press Dieffenbacher PO250 with magnetic tool fastening. The deep drawing tool was designed and constructed. For series of 2 000 units per year the rate of return was calculated after 4,7 years, while using the punch from the current second deep drawing operation it was calculated after 3,4 years.

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.

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.

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
