Description
Technical field
The present invention relates to the automatic wet press of a kind of magnetic material, the hydraulic system variable control device of the automatic wet press of particularly a kind of magnetic material.
Background technology
At present, magnetic material has been used among our life widely, and the magnetic material of industrial use is mainly tile-shaped magnet.The production technology of tile-shaped magnet is mainly: slip preparation, compacting, sintering, mill processing etc.Wherein, the suppression process of tile-shaped magnet is many to be finished by semi-automatic or full-automatic wet press, and this operation directly has influence on quality, production efficiency and subsequent handling stable of tile-shaped magnet.In the pressing process of tile-shaped magnet, the compacting oil cylinder of wet press have respectively fast down, matched moulds, press soon, kinds of processes requirements such as pressure, release, backhaul slowly, the traffic demand in the whole pressing process changes.In order to satisfy this technology requirement, the hydraulic system of existing wet press mainly comprises following two kinds:
A kind of is to adopt big or small oil pump to control jointly, and the high-pressure low-flow pump is mainly used in the whole pressing process of control, and the low pressure and mass flow pump is mainly used in the quick forward and back of control oil cylinder.This hydraulic system exists that reactive loss is more, system's heating is wayward; Need be aided with more flow control element, the shortcoming that system failure source is many, failure-frequency is high.
Another kind is the flow that employing ratio oil pump and proportional control element come control system.This HYDRAULIC CONTROL SYSTEM is accurate relatively, but element cost height, the general user is difficult for accepting.
Summary of the invention
The objective of the invention is to:, provide the hydraulic system variable control device of the automatic wet press of a kind of magnetic material at the problem of above-mentioned existence.This device is skillfully constructed, simple in structure, production cost is low, failure-frequency is low, has realized accurate control.
For achieving the above object, the technical solution adopted for the present invention to solve the technical problems is:
The hydraulic system variable control device of the automatic wet press of a kind of magnetic material, comprise fuel tank, oil suction oil filter, oil pump, frequency control motor, pressure regulatory element and executive component, described oil suction oil filter is connected with fuel tank by pipeline, described oil pump is connected with the oil suction oil filter by pipeline, described frequency control motor is connected with oil pump, be used to realize controlling the fluid of oil pump output different flow, described oil pump is connected with executive component with pressure regulatory element.
As optimal way, described oil pump is a hydraulic oil pump.
As optimal way, described oil pump is quantitative oil pump or variable capacity oil pump.
As optimal way, be provided with ball valve between described oil suction oil filter and the oil pump.
As optimal way, described frequency control motor is the variable-frequency motor of Frequency Converter Control or the common electric machine of Frequency Converter Control.
As optimal way, described pressure regulatory element also is connected with pressure detecting element.
The present invention utilizes frequency control motor to control the fluid flow of oil pump output, frequency control motor is realized speed change by the variation of incoming frequency, thereby adjust the output flow of oil pump, change the speed of service of executive component, satisfy the different demands of the automatic wet press of magnetic material to the oil pump output flow, variable is reliable, and range of variables is big, can realize stepless speed regulation, the reactive loss of system approaches zero; Reduce the Hydraulic Elements consumption, simplified system architecture, reduced failure-frequency.
For many years, uppity technical bottleneck that the hydraulic system of the automatic wet press of magnetic material always is difficult to break through system complex, the element use is many, reactive loss is big, energy waste is serious, system generates heat, also restricted the skill upgrading in this field, the magnetic material industry was paced up and down all the time in high energy consumption, stage that technical merit is low.The present invention utilizes the power of frequency control motor as the hydraulic press hydraulic system, be aided with brand-new system element configuration, broken through historical Design Thinking pattern fully, overcome the many unvanquishable at all defectives of old design, as the energy-saving and cost-reducing significantly technical support of the sector.
The present invention is skillfully constructed, simple in structure, production cost is low, failure-frequency is low, has realized accurate control, variable is reliable, range of variables is big, can realize stepless speed regulation, the reactive loss of system approaches zero.
