Abstract

The invention discloses a vibrational casting experimental device. The device comprises a rack, a sample mould, a mould installing device, a vibrating device, a damping device and a vibration direction adjusting device, wherein the vibrating device comprises a vibration motor installing board, vibration motors installed on the vibration motor installing board and speed controllers for controllingthe vibration motors; the damping device comprises damping springs, compression springs, compression spring supporting bases and compression spring adjusting bolts; and the vibration direction adjusting device comprises an adjusting screw rod, an adjusting rotating arm and a supporting arm. The device has the following advantages: different frequencies of vibration can be obtained by adjusting the speed controllers; different amplitudes and vibration forces are obtained by adjusting the compression spring adjusting bolts or amplitude adjusting devices carried by the vibration motors; linear vibrations in different directions are obtained by the adjusting screw rod; linear vibrations at different angles are obtained by changing the installation direction of the sample mould; and linear vibrations or three-dimensional circular vibrations are obtained by the vibration motors, thus meeting the experimental requirements of metal materials for different vibration frequencies, amplitudes andvibration directions.

Description

technical field [0001] The invention relates to the technical field of vibration casting, in particular to a vibration casting experimental device. Background technique [0002] At the beginning of the 20th century, the research on the application of vibration in the field of metal solidification has attracted extensive attention. The research objects involve ferrous metals, non-ferrous metals and their alloys, among which aluminum alloys are the most widely studied. According to different methods of generating vibration, vibration equipment can be divided into mechanical, pneumatic, electromagnetic and ultrasonic vibration. A large number of studies have concluded that ultrasonic vibration, electromagnetic vibration or mechanical vibration applied to the solidified metal melt will promote the nucleation of the metal, break the dendrites (grain refinement), reduce segregation (homogenize the structure), remove Gas removal of impurities (purification of the melt), enhanced ...
