The aim of this thesis is to design a clamping unit with mechanical multiplier. Unit will serve as a technological clamping element in the technical equipment. My task was to select the method of construction and design driving main unit for grip jaw. I chose a solution with a mechanical multiplier. The frame unit is made up of fixed and sliding clamping jaw and is self. Unit is designed as a built module. The entire structure must be designed to meet the initial parameters specified in the award of thesis. The main parameters include clamping strength of 80kN, the extent of working stroke 15 mm and the size of a scroll, which is 250 mm. They are also listed in the award size constraints: the length, width, height dimensions and the coupling unit.

This paper studies a method for active electrohydraulic force compensation in industrial scale high power applications. A valve controlled cylinder moves a mass using the force of inertia to compensate for the reaction forces of an industrial process. Two strategies for force compensation are developed and investigated in a 160 ton clamping unit of an injection moulding machine to significantly reduce the excitation. Results of the different strategies are shown and evaluated. Advantages and drawbacks of the developed electrohydraulic force compensation are discussed.

Design servodrive clamping unit with pneumatic or mechanic multiplier. Unit has be instrumental to strength clamp parts in tension technical machines. Frame unit’s is complicate from massive and movable clamping board and is self-supporting. Unit has be solution like incorporated modulus. Target is proposal main driving period for movable clamping board. Work up proposal constructional solution, drawing listings, production drawing of the three engaged part of, BOM. Computational report must include calculations drives, constructional knots and their verification and further needed strength calculation and analyses. Proposal treatment tribotechnical knots. Analysis construction from standpoint safety in operation according to NV24/2003 and analysis safety hazards. Part of work must be and economic analysis resultant solution.
