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.

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 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.

Proposal of production technology of trough
Rérych, Pavel ; Staněk, Vojtěch (referee) ; Podaný, Kamil (advisor)
Elaborated thesis presents a proposal of technology for the production of modular. The modular is manufactured by ACO Industries k.s. from stainless steel 17 240 with thickness 1.5 mm. Literary studie is focused on Bending as the most favorable technology with respect to tender documentation. Based on technological calculations and available machinery TruBend 5130 press with nominal force 1 300kN was selected for part manufacturing process. Forming tools are made of Cr - Mo tool steal. The thesis also includes technical and economic evaluations.

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

Production of cap
Braško, Zdenko ; Staněk, Vojtěch (referee) ; Podaný, Kamil (advisor)
The aim of this thesis is to propose and design the production of the cap. The cap is welded to the tube of roller regal and is used for closing the tube. They together make a fixed assembly. There is a bearing molded from inside the cap and shaft passes through the center of the cap. The main function of whole assembly is to rotate the tube around its own axis. The cap will made from deep - drawing steel DC04 with a thickness of 2 mm. After consideration various possible variants for the cap production, there was chosen deep drawing without reduction of thickness as the most profitable technology. The shape of the component was modified from the technology review. There is proposed a tool that will be used for production the caps. The caps will be produced within three operations: the first two operations form a central cup and the third operation makes the final shape of the cap. Drawings for the tool are created and delivered as part of this thesis. Based on the necessary force and work calculation, it was chosen eccentric press machine S 160 E from the ŠMERAL company. With the 25 000 series, the costs of production one piece are 51,65 CZK.

Optimization of components production on draw press
Rérych, Pavel ; Staněk, Vojtěch (referee) ; Podaný, Kamil (advisor)
The diploma thesis present technology production of draining outlet. This is a rectangular deep drawn part, where basic shape is formed in two towing operations now. The used material is an austenitic stainless steel 17 240 with thickness 1 mm. According to the entry documentation the production technology was not change – current technology (it means drawing without thinning the wall) is most suitable. Based on technological and control calculations two-operations production was determined, which will take place in the united conventional instrument. The hydraulic press with marking Dieffenbacher PO250, which has a magnetic tool clamping, per stroke will perform here both operations. The payback was calculated for yearlong production 50 000 pieces after 0,8 years. The proposed production will make the current production more efficient including economic benefits.

Venc, Jan ; Staněk, Vojtěch (referee) ; Podaný, Kamil (advisor)
The thesis presents a proposal of a hygienic trough. The trough is made by the company ACO Industries k.s. from stainless steel 17 349 of thickness 1,5 mm. Literary studie is focused on respect to hygienic requirements, which are defined by EHEDG. The trough was valorized and necessary adjustments were proposed to meet the conditions.
