The project elaborated in frame of the engineering studies branch N2326 presenting the design of manufacturing technology of forging carrier of steel 14 220. Pursuant to the literary pursuit a problem of solid hot forming was proposed to product by drop forging with flash on 3 forging operations. All the operations are realized on the vertical crank forging press LZK 4000 B produced by ŠMERAL BRNO a.s. with nominal forming force 40 NM. Heating material on the forging temperature 1100 °C will proceed in the electric induction furnace produced by ROBOTERM s.r.o. type KSO 800kW, the flash trimming on the trimming press LDO 315 A/S with nominal forming force 3,15 MN. Dies are made from tool steel 19 552.9 and strapped in die holder QLZK 4000/UC. A part of the project is technical economic analysis evaluation and elaboration of production scheme. Expected annual volume is 100 000 pieces.

The aim of the diploma thesis is design construction and calculation of mechanism for parallel run of ram and adjusting position of ram in the face of table board of vertical hydraulic press. First part of thesis is about design calculation of vertical hydraulic press ram. Second part focuses on design calculation of ram and hydraulic cylinders. Third part solves design and construction of positioning hydraulic–electric system. Final fourth part analyses press construction from aspects of safeness, riskiness and economical factors.

The project, which have been created within the framework study of engineering branch N2301-2, submit technology project of presswork – car reinforcement from material H 220 P and concept of multi-tool set design for pressing operations 1, 2 and 3. Technology process was designed in six operations, based on literary study of blanking and drawing technology. Multi-tool set is design in according with transfer press Müller Weingarten 1250T-1, which was chosen on the basis of advantageousness calculation. Project includes technical and economical evaluation of elaborated technology whit two other variants of production.

This diploma thesis has been elaborated within the Master's study that submits a production proposal of carrying body by solid forming. The forging has been performed using drop orging method at the crank forging press LZK 1000. Heating is inductive and flash trimming has been peformed in the trimming press LKOA 200. The used material of the forging is steel CSN 14 220. Production series is 100 000 pieces. A part of this thesis is calkulations, geometric design and economical evaluation.

The project elaborated in frame of engineering studies branch Manufacturing Technology (N2307-00) is submitting design of technology production of the latch claw. The latch claw is a component of a car side-door latch assembly and can be used for different car models. The part is made of sheetmetal 4 mm thick. The material for the part is 15CrMo5, alloy steel for case-hardening purposes. Pursuant of the literary pursuit was designed several options of the part manufacture. With regard to required dimensional accuracy, cut-edge quality and expected production run (800 000 pcs. per year) was proposed manufacturing the part by fineblanking technology. Fineblanking is a cost-effective manufacturing method for accurate sheetmetal parts. For manufacturing parts was chosen Feintool hydraulic fineblanking press HFA 3200plus with total force 3200 kN. The press is coupled to a coil reel a strip straighter. Both units of Feintool feeding line FBA 8/300 are very compact, reducing space requirement. For the fineblanking tool design is used a moving-punch system because these tool systems are compact and economical to make and use. The tool make use of standardized cast iron fineblanking die set made by Fibro company. At the conclusion was compared the cost-effectiveness between two production methods – fineblanking with that of laser beam cutting.

This diploma thesis, which has been elaborated within Master's study programme Manufacturing Technology and Management in Industry (2303T005), submits a production proposal of production of bottom body by solid forming and its economical evaluation containing all the economical essentials needed in order to produce and specify the final price of a forging. This thesis takes in all the necessary calculations and machinery proposals according to the material of dies and to annual capacity of 250 000 pieces of forgings requested. Semi-finished product for the manufacture of forging is cut size of bars of circular cross-section of steel 14 220 ČSN 42 5510.

The diploma thesis deals with problems of drop forging. A detailed literary study is prepared in this work, in which there are data for working out the specified component – mudguard holder. There are options for cutting the semi-product, types of lubricants, construction of ideal preform or different kinds of forging machines for drop forging. The next part of this thesis is about technology of drop forging on crank forging presses. This section is aimed on technical drawing of the forging and its classification by the complexity of the shape. Furthermore, the thesis deals with the economic part, setting out the individual costs of the production from which the cost price of a forging is determined.

This thesis deals with design of 3 axis manipulator which manipulate wit ball bearing and moulding of pulley. Moulding of pulley is product of injection press. Part of this work is also technical-economics valuation of manipulating possibilities with ball bearing and pulley and is determinate the most useful option. Next is work out a conception of conveyor for ball bearings and pulleys.

The project developed as a part of continuing master’s program in the field of M-STG Mechanical engineering technologies introduces a technological proposal of producing a side panel of computer case. Based on the research of published studies on the topic of surface forming and methods of production of shape openings in sheet-metal, we chose the variant of production of parts using punch press and press brake and selected appropriate material – steel with protective zinc and aluminum coating. Based on the research of published studies on the topic of computer cases we processed analyses of shape designs and chose optimal variant, for which we prepared calculations of production costs in comparison with other proposals.

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.
