Drop forging of pinion
Gráf, Radomír ; Dvořák, Milan (referee) ; Štroner, Marek (advisor)
The project elaborated in a frame of Bachelor’s studies branch Manufacturing technology (2303R002) presents a technology design of a forged piece – pinion gear – made by drop forging from 14 220.0 (16MnCr5) material. Drop forging in two operations was suggested on the basis of specialized studies on the subject of drop forging and calculations. Assumed series of 120 000 pieces a year, will be produced on the drawing inclinable press LMZ 1000 A/(S) with nominal tensile force 10 MN. Swages are made of alloyed instrumental steel 19 552.8, heat-worked according to drawing documentation. At the end of the project is implemented technical economic evaluation of the technology design.

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.

Production of pinion
Matsiuk, Oleksandra ; Lidmila, Zdeněk (referee) ; Podaný, Kamil (advisor)
The bachelor's thesis deals with the design of the production of pinion – small gear made of steel 14 220. After analyzing all possible production methods, the technology of die forging on a hammer in the single-die was chosen. Based on a literature study of the issue and relevant calculations, a semi-finished product with a length of 151,8 mm and a diameter of 63 mm was designed. Hammer KHZ 4A with forming energy of 50 kJ was chosen. A single-die was constructed on the basis of valid state standards. Auxiliary machines were also chosen for production – band saw, induction heater, shearing press and drum blaster.

Production of gear
Havlíček, Roman ; Řiháček, Jan (referee) ; Podaný, Kamil (advisor)
The thesis deals with the design of production technology of the chain wheel used in the scraper conveyor made of 14 220 steel. After considering all production options, die forging was selected. On the basis of chosen technology, shape adjustments, additions and dimensional tolerances were made. From the volume of the forged wheel, a semi-finished product with a diameter of 150 mm and a length of 106 mm was determined. Based on the scale of series, the machinery equipment of the company and the size of the forged piece, the KHZ 16A hammer, with a nominal energy of 160 kJ, was chosen as a forming machine. According to the standards, a single-die dies were designed for the forging. The LKOA 200 press was chosen to cut off the flash and the membranes. Additional machines for manufacturing were chosen and technological standard was compiled. At the end costs of the material for production amounting to 2 566 045,3 CZK and the cost of production of die in the amount of 187 000 CZK were calculated.

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.
