The invention belongs to the field of wet pressing forming of permanent magnetic ferrites, discloses a three-servo floating type automatic hydraulic machine for wet pressing forming of permanent magnetic ferrites, and mainly aims to solve the problem of poor quality of final products caused by inaccurate control of a hydraulic system of an existing hydraulic machine. According to the hydraulic system, three independent motor pump sets are adopted as driving sources, and each driving pipeline adopts an independent integrated block design, so that each working cylinder body can be accurately controlled and does not interfere with one another in the working process, and the thickness error after a product is formed is reduced; meanwhile, the three motor pump sets can operate separately so as to achieve energy conservation and consumption reduction, and can also work simultaneously so as to shorten the pressing period.
Description
technical field [0001] The invention belongs to the field of wet-press forming of permanent magnet ferrite, and more specifically relates to a three-servo floating automatic hydraulic press for wet-press forming of permanent magnet ferrite. Background technique [0002] With the development of industry, magnetic materials have become the basic functional materials of the electronics industry, and permanent magnet materials, as an important part of magnetic materials, play an important role in the electronics industry, information industry, motorcycles, electric tools, automobile industry and other industries. role. The main component of permanent magnet ferrite is iron oxide, and its production process is roughly as follows: After the raw material is pre-fired at high temperature, it is crushed into 5um~8um particles by a dry ball mill, and then mixed with a certain amount of water and The iron oxide particles of steel balls are ground to a slurry of 0.8um to 1.2um, and the...
