An automated Regulator for the Excess Amount of Oil for the Hydraulic Press Assembly

Abramov I.V., Abramov A.I., Bashar S., Romanov A.V.


This paper presents an automated regulator for maintaining oil pressure during press-fitting of the parts assembles using the hydraulic press method to improve the stability of the hydraulic press assembly process and the quality of the assembled joints with guaranteed interference fit. The regulator is based on a hydraulic accumulator and a power mechatronic mechanism with a forward movement of the support in the vertical direction. The power mechanism ensures the displacement of the plunger of the accumulator, which allows regulating the working volume of the accumulator cavity, which receives the oil resulting from coupling zone parts during press-fitting process and thus regulate the oil pressure in the system. Further in this paper the design, structure and kinematic schemes of the developed regulator are presented. The force sensor serves as a feedback and provides automatic control over the stroke of the power mechanism and the connected in series hydraulic accumulator plunger. To regulate the speed of the motor, a frequency converter is used which is set to operate in the scalar and inertial stop mode to ensure smooth acceleration and rapid braking of the hydraulic station engine. The testing results of the regulator for the ability to maintain pressure in a given range confirm its performance and compliance with the requirements imposed by the hydraulic press assembly of the interference fits.
