On behalf of Inspectera HK AB in Norrköping a web-based drawing tool has been developed in Java, mainlywith the library Google Web Toolkit (GWT). The purpose of this tool is to facilitate both the staff's at Inspecteraand their client's work with different types of drawings such as blueprints for pest control, fire protection andespecially drawings of the company's e-service of self-checks. Besides developing the drawing tool usabilitytesting and a usability evaluation has been performed.

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.

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.

Thesis evaluaes production of the body latch, which is used for window, window shutter and door locking. It is made from 11 375 steel sheet which is 1 mm thick. Annual production is 50000 pcs. Progresive cutting and drawing in one combined tool and finishing product in single opperation drawing tool was choosen as most effective. Single operation drawing will be operated manually. Tools was designed by series of technological callculations to which was projected presses Šmeral LDC 160 with additional devices. Acording to economic valuation, cost of production of one piece is 16,50 Kč and production becames profitable after production of 27185 pieces.

Thesis submits concept of the sink fabrication technology where circular sink is made from rustproof austenitic steel 1.4301 (X5CrNi 18-10) using technology of conventional deep drawing without reducing wall’s thickness. Hydraulic press YL32 - 400 with nominal force 400 kN has been chosen as the production machine. Drawing tool with holder was designed to be used for this technology and its drawing documentation had been enclosed in this thesis. Size of the production series was set for 20 000 products annually. Control simulation of the drawing process has proven that designed component can be made and that computations are correct. Economic and technological estimation was performed which resulted in price being set for 555 czech crowns per piece. After manufacturing first 7 447 products the manufacturing process will become economically profitable.

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.

Master’s thesis submit a concept for belt drive cover manufactured by ČSN 411320.21, a 1.5 mm thick material for series 10 000 pieces. On the basis of manufacturing method are presented problems around drawing, the parameters, used machine with tool design. For deep drawing operations were carried out control, computing technology, a hydraulic pres CTH 250 selection, designed set of drawing tools, simulation by AutoForm software, a technical economic evaluation, break-even point and supported by drawing documentation.

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.
