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. Based on proposed profile and on the main volume makes custom production, was selected Bending as the most favourable technology for construction and WIG method for welding.
Optimization of manufacturing process of tubes
Kohout, Jaroslav ; Staněk, Vojtěch (referee) ; Podaný, Kamil (advisor)
Elaborated thesis presents a proposal to increase welding speed in the process of production of stainless steel tubes 1.4301 and 1.4404. Based on analysis of the existing method was evaluated, that performance improvement would be most appropriate by adjusting the welding technology. Four methods have been proposed, describing the principle, andvantages and disadvantages. The most effective and cheapest was the modification of the existing TIG method using two torches, with the possible improvement of using another shielding gas.
Manufacturing of the support arm
Melichar, Ivo ; Staněk, Vojtěch (referee) ; Podaný, Kamil (advisor)
The thesis introduces a design for the technology of manufacturing the supporting arm used for positioning and rigidity of the front plate in relation to the metal socket in the container box. The arm is made of a 2 mm thick steel sheet and of a quality according to ČSN 411331 in a production series of 14,700 units / year of the left modification and 14,700 pieces / year of the right modification. After the assessment of individual production options, the cutting technology in a progressing tool and bending technology in a simple tool were selected. Based on a literary study on cutting and bending, an optimal process of arm manufacturing was proposed. After the design, technological and control calculations for individual technologies, the tools were designed, and the technical documentation for those tools was developed. For the cutting technology, an Andritz Kaiser press with a PV120F / 1 labelling was selected. For the second production step, bending technology, a press from Šmeral Brno a.s. with a LEN 63 labelling was selected. Both of these presses meet the requirements of both the forming force and the tool dimensions. After the economy of production was assessed, production costs of one piece were determined with a 30 % profit assumed to 28.47 CZK. The turning point when production became profitable was found after the production of 18,121 units.
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 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.
Production of grill lid
Míka, Tomáš ; Staněk, Vojtěch (referee) ; Podaný, Kamil (advisor)
The thesis is focused on the design of the production of kettle grill lid from steel 11 305 (1.0338) with a constant wall thickness of 1 mm and a series of 10 000 pcs/year. For the selected method of manufacture by conventional drawing, technological calculations were performed. Depending on the diameter of the blank, maximum force and other parameters, the tool and the machine were designed. The tool is a single-operation drawing tool with a blank holder and a rib around the perimeter. These functional parts, together with the drawing punch and drawing die, are made of surface-treated cementitious steel 14 220 (1.7131). The drawing tool is clamped into a CBA 250 hydraulic press with a nominal force of 2 500 kN, where the blank holder is controlled by an additional device at the bottom of the press.
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 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.

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.
