Drop forging of gear wheel
Bezděk, Pavel ; Dvořák, Milan (referee) ; Štroner, Marek (advisor)
Objective of this bachelor thesis is design of forging of gear manufactured by die forging. Material of gear is steel 12. According to number of forgings per year, forging of gear will be done on vertical forging press LMZ 2500 with nominal forming power of 25 MN. Dies are made of middle doped steel 19 552. In conclusion, costs of producing of gear forging with selected manufacturing technology are evaluated.

Production of holder by solid forming
Špaček, Antonín ; Štroner, Marek (referee) ; Kopřiva, Miloslav (advisor)
The diploma thesis deals with suggestion of low alloy 14220.0, produced by solid forming. This suggestion is based on the size of series that contain 100 000 pieces a year. The essay contains knowledge refering to drop forging technology and comparison with existing technologies. Two suitable variants of production were assessed, these variants are drop forging with hammers and vertical forging press. Both theories were theoretically analised in order to describe given technology. The analysis also contains calculation and suitable machine choice. Drop filling on vertical forging presses was chosen because of forging type. Furthemore forging proposition was treated including production technique. The chosen variant contains calculation, suggestion of a die, machine that was used and suggestion of flash trimming. For suggested technology was chosen vertical press LZK 3150 B. Its producer is Šmeral a.s. Brno. This project also contains technical drawings of the given component, forge, dies and phase of forging.

Modifying of the eccentric shaft and gear for vertical forging press
Masařík, Adam ; Kolář, Ladislav (referee) ; Kalivoda, Milan (advisor)
This diploma thesis deals with the design and realization of a detachable joint for transferring a large torque from a drive to a driven member in a vertical forging press. The first part analyzes the disadvantages of production, assembly and disassembly of the original wedge joint of eccentric shaft and gear. The design of a new detachable joint is intended to remove the disadvantages of the original joint. Verification calculations are part of the proposal. The next part deals with the production of joint elements and the modification of the connected components for the designed joint.

Drop forging of flange
Bednář, Jaroslav ; Řiháček, Jan (referee) ; Štroner, Marek (advisor)
The aim of the project developed within the framework of the Bachelor's degree in Institute of Manufacturing Technology is the design of the production of a flange forging by die forging from alloy structural steel 14 220 (1. 7131). Size of production is set on 100 000 pieces per year. Based on calculations, the LMZ 4000 vertical forging press with a forming force of 40 MN is selected for production. Three production operations are selected for a given production. Forging dies are designed using an ejector. The material of the dies is alloy instrumental steel 19 552.8 (1. 2343). At the end of the project, a technical and economic evaluation is carried out where a price comparison and costs for the production of die forging and machining are given.

Drop forging of gear wheel
Bradáč, Tomáš ; Kopřiva, Miloslav (referee) ; Štroner, Marek (advisor)
This master´s thesis submit a project of technology of production of gear wheel the way of drop forging. A part is made of steel 14 220.0 (16MnCr5). A semi-product is a stick of parametres o75 - 211 ČSN EN 10060, with a production of 130 000 pieces a year. Technological process of drop forging are worked up based on a study presented in technical literature. A forging will be working up on a vertical forging press LMZ 1600 A made in Šmeral Brno, Inc. For this option, the required technological calculation, drawing documentation and forming process simulation which is implemented by way of the software FormFEM have been carried out. Technical and economical evaluation of the component technology producing is brought in as a conclusion of the thesis.

Drop forging of pinion
Cvrček, Jan ; Dvořák, Milan (referee) ; Štroner, Marek (advisor)
The final project has been elaborated in a frame of Bachelor’s studies branch Manufacturing technology assesses design of production pinion by method of die forging. The pinion is manufactured from alloyed structural steel 14 220 (1.7131). Size of production is set on 100 000 pieces per year. The pinion will be forged on the vertical forging press LMZ 1000 A with forming force 10 MN. The forging is formed in two operations. Forming tool is manufactured from alloyed instrumental steel 19 552 (1.2343). In the last chapter of the project is described the price comparison and costs for manufacture of die forging and machining.

Drop forging of gear wheel
Bednařík, Petr ; Lidmila, Zdeněk (referee) ; Štroner, Marek (advisor)
The project elaborated design of technology production of gear wheel from circular blanks of steel 12 050. Pursuant to of the literary pursuit a problem of the die forging and calculation was designed manufacturing process. Dies proposal will be based on relevant standards, materials die steel will be 19 552. Given the complexity of the shape and dimensions of the gear will be used in three operations. Based on the calculated forging force was chosen vertical forging sheet LMZ 1600 A/S with a nominal power of 16 MN. Due to the use of the press die is provided with an ejector.
