Design of robotized workplace for die forging
Krejčí, Radek ; Zavadil, Radek (referee) ; Podaný, Kamil (advisor)
The thesis deals with the design of technology for production of wheels to be manufactured by die forging 15 142 low-alloy steel at an amount of 500,000 items per year. Based on a consideration of the suitable methods of manufacture, die forging on a Jing Duann FP-1600G vertical forging press was chosen as the best, as documented by the necessary technological and design drawings. A die with inserts made of 19 552 steel was designed for this machine. In view of the volume of annual production, a fully automated workplace was designed consisting of three robots and a chain and pan conveyor. In the conclusion there was a technical-economic evaluation of costs for the material of the semi-finished products and price of dies for annual production.
Production of chain wheel
Haltmar, Vojtěch ; Štroner, Marek (referee) ; Lidmila, Zdeněk (advisor)
This bachelor’s thesis deals with the production of chain wheel using the method of die forging. The wheel is made of C45 steel and is a part of the transmission of construction machinery. Based on the required mechanical properties of the component and batch production which amounts 20,000 pieces per year, three operations die forging is proposed for the production. An intermediate good for the production of the wheel is a cylindrical block with a 50 mm diameter and length of 100 mm. The forming machine for the production is vertical forging press LMZ 1600 P/SH with the nominal force of 16 MN. The trimming press LKOA 200 with the nominal force of 2 MN is used to remove the excess material. Forging dies are produced from tool steel ČSN 19 650 and are based on the technical drawings. The thesis also compares the production of chain wheel by machining and die forging concluding that the use of die forging method saves an amount of 42 CZK per piece.
Forging oblong forgings
Příkaský, Jakub ; Štroner, Marek (referee) ; Lidmila, Zdeněk (advisor)
The project deals with the design of the production of a rod-shaped component using a die swage. The material is steel 12 060. Based on a literature study on forging and calculations, the forging, the technological process and the hammer die were designed. Based on the calculated work required, the power hammer KHZ 2 was designed. Technical and economic evaluation was performed.
Production of the piston rod eye
Vahala, Jiří ; Štroner, Marek (referee) ; Podaný, Kamil (advisor)
The project deal with technology design of production of the piston rod eye from steel 11 523 in the amount of 30 000 pieces. From various possibilities of technology was chosen as the most optimal method the technology die forging. Pursuant to the study of literature and calculations there will be made the forging as a double-edged in single-cavity die on hammer witch several hits in finishing hollow. According to the calculated energy there was selected pneumatic-hydraulic hammer KHZ-4A witch stated energy of 40kJ. The tool was made of steel 19 552, heat-treated according to the drawing documentation. The technical and economical evaluation was focused on the total material cost of the semi-finished material and the cost of manufacturing forging die, which is 1 229 507 CZK in total.
Issues of hammer die forging
Žižka, Jiří ; Štroner, Marek (referee) ; Podaný, Kamil (advisor)
This bachelor thesis deals with issues of hammer die forging which is technology that is mainly used for the production of shaped and height-versatile and rugged forgings with ribs and protrusions. Forgings are made by several blows of the tools which are called dies. Design of forgings is based on drawing documentation. For successful production of the component it is important to choose right forging temperature, parting line, required additions and tolerances. Hammers are machines which work with hit energy, they use kinetic energy for forming the material. Their characteristic features are good climbing of the material and filling deeper chambers in direction of the hit. Several types of hammers are used, for example fall hammer or double acting hammer and more.
Manufacturing of eye
Skalník, Petr ; Štroner, Marek (referee) ; Podaný, Kamil (advisor)
The project follows up design of technology manufacturing of eye, which will be made by drop forging from low-alloyed steel 13 242. Yearly production is set on 300 000 pieces. Pursuant to of the literary pursuit problem and calculations will be the forging made on a hammer with several hits in the finishing hollow. Regarding to calculations of forging work is elected pneumatic-hydraulic power hammer KHZ – 2A with energy of 20 kJ. Die is made of tool steel 19 663 heat-worked according to drawing documentation. Technical and economical evaluation was aimed on a calculation of production expenses of semi-produced material (3 323 109,40 CZK) and on price of the forging machines for yearly production (930 000 CZK).
Drop forging of pinion
Mikeš, Filip ; Žák, Ladislav ; Štroner, Marek
The project deals with the design of the requested part, with technology of volume thermoforming – drop forging. The literature study was written according to this technology and the design of pinions manufacture from steel 14 220 was made. On the basis of the calculated forging force, the molding machine LZK1000P/SH, from the company Šmeral Brno, a.s., and other necessary machines were chosen to manufacture the forged piece. According to chosen machines and calculated parameters, the manufacturing process, the drawing documentation and the technical – economic evaluation were compiled.

Method development of forged piece in conditions of modern forge
Vraštiak, Michal ; Psík, Eduard (referee) ; Podaný, Kamil (advisor)
Taking into account modern technology solutions has been selected die forging of the wheel hub of automobile steel 14220 (DIN 16MnCr5) about the serial 50000 pcs. Based on the literature study and practical experience has been solved forging process, including technological calculations, engineering drawings and results of simulations of the forging process performed by the Qform software tool. A tool was designed to be made of 19552 grade alloy tool steel. The forged piece is to be forged on an LZK 1000 crank press with the nominal forming force of 10 MN manufactured by Šmeral Brno. The stock is divided with shears from bar 45 mm 6 m long to bar 89.5 mm long.
Production of holder by solid forming
Šimon, Miroslav ; Novotný, Karel (referee) ; Kopřiva, Miloslav (advisor)
The aim of this dissertation is to design an optimal technological processing of a given component by solid forming. This work includes a bibliographic study, which is the source of information for the solutions. Another important topic is the global technological processing of the given component: to begin with gear blank design until the final product. The best option seems to be the die forging on forging press in three steps. From an economical point of view, the die forging realized according to the designed technological processing appears to be the best solution.
