Hydraulický lis s proporcionálním řízením

Abstract

The diploma thesis deals with the design of hydraulic press drive with proportional technology. In the introduction, the work focuses on description and function of the hydraulic presses. Furthermore, possible variants of the drive and its modern concept are outlined. The work takes into account the safety requirements for the hydraulic presses, which are determined by the legislation. The aim of the practical part is to design a drive unit for specified parameters and construction of a four-column hydraulic press. The hydraulic press will be used to cut wedge bars. The design of the drive is therefore based on the cutting operations and the required force. The practical part of the work is processed in the form of a project and contains production documentation of the hydraulic cylinder, functional diagram of the hydraulic circuit, heat balance calculation, element specifications, engine list, instruction for the related profession of electrical engineer and instructions for operation and maintenance of equipment.
