Abstract

The invention discloses an oil-free pump, a hydraulic vibration exciter with adjustable frequency and amplitude and an adjustment method thereof, belonging to the field of dynamic assisted plastic processing. In the oil-free pump and hydraulic vibration exciter with adjustable frequency and amplitude of the present invention, the tapered roller cooperates with the conjugate end face cam to convert the rotation of the motor into the reciprocating linear motion of the piston rod of the vibration exciter in the cylinder body, and the The hydraulic oil acts on the piston of the hydraulic cylinder through the valve body, and the movement frequency of the piston of the hydraulic cylinder changes with the rotation speed of the motor, so that the frequency is adjusted; the flow rate of the valve body is adjustable, and the flow rate of hydraulic oil flowing into the hydraulic cylinder body can be adjusted, thereby The vibration amplitude of the hydraulic cylinder piston; the oil-free pump, adjustable frequency and amplitude hydraulic vibration exciter of the present invention has compact structure, simple form, does not need hydraulic pump station and complex reversing system, and can realize the stepless amplitude and frequency of the vibration exciter Adjustment, can be applied to large load vibration assistance. The adjustment method of the invention has simple operation.

Description

technical field [0001] The invention belongs to the field of dynamic assisted plastic processing, in particular to a hydraulic vibration exciter without an oil pump, adjustable in frequency and amplitude, and an adjustment method thereof. Background technique [0002] Vibration plastic processing is an emerging interdisciplinary subject developed in the field of plastic forming by using vibration in recent years. The coupling of vibration field and plastic force field can significantly reduce material flow stress, reduce friction, improve material structure and surface quality, and It has the integration of forming and forming. Vibratory plastic processing technology has great advantages in the processing of difficult-to-form materials, and is widely used in the field of micro-forming of metal materials such as titanium alloys and magnesium alloys. However, at present, the vibrators used in vibration-assisted plastic processing technology are mainly ultrasonic exciters. The...
