Description
Technical field
The utility model relates to a kind of hydraulic stations of servo motor, belong to technical field of hydraulic equipment.
Background technique
In permanent-magnet material production technology, need to carry out extrusion forming to mixture using forming press, forming press is by hydraulic
It stands and pressure is provided.After compressor operation end cycle, motor not only wastes energy consumption but also makes common hydraulic station also in running at full capacity
Hydraulic station temperature increases, and the pressure transient in pressing process influences product quality.Patent CN201520497838.6 is provided
A kind of energy-saving servo hydraulic station is to drive hydraulic pump using servo motor, and motor is changed to servo motor, servo by ordinary motor
The revolving speed of motor is adjustable, and the Setting signal of pressure and flow is converted into DC0-10V or 4-20mA signal and driven to servo by hydraulic station
Dynamic device, servo-driver drag servo motor rotation again and provide the power source of flow system flow and pressure.Servo-driver acquisition system
The real-time traffic and real-time pressure of system constitute the double loop system of flow closed-loop control and pressure closed loop control, and control precision is high,
Pressure is constant and energy-saving effect is obvious.The problem is that electric signal for controlling servo motor has instantaneity, and servo
For motor after adjusting revolving speed, pressure change has hysteresis quality, at the initial stage of compression moulding, servo when being transferred to pressure sensor
Motor needs to provide biggish power and pressure is kept to stablize, and servo motor is be easy to cause to overload, and the overload energy of servo motor
Power is generally lower, therefore the above problem may cause servo motor overload and damage.
Utility model content
The purpose of this utility model is to provide a kind of hydraulic stations of servo motor, the specific scheme is that
A kind of hydraulic station of servo motor, including fuel tank, servo motor, hydraulic pump, servo motor drive hydraulic pump works,
The oil inlet of hydraulic pump connects fuel tank, and the flowline of hydraulic pump with the hydraulic cylinder of forming press for connecting, the flowline of hydraulic pump
Equipped with pressure sensor, for pressure sensor for testing out tubing pressure and controlling servo motor, the flowline is connected with cylinder
The pressure compensation chamber of shape, the pressure compensation chamber include balance cylinder and storage pressure chamber, are equipped with piston section between balance cylinder and storage pressure chamber,
Piston section is equipped with piston, and balance cylinder is connected to flowline；The storage pressure chamber is equipped with compressed air interface.
Further, the pressure compensation chamber is stainless steel cylinder, and stainless steel cylinder is connect by triple valve with flowline.
Further, the piston section of the pressure compensation chamber is equipped with Double decker piston, is equipped with oil emulsion between Double decker piston.
Further, the storage pressure chamber of the pressure compensation chamber is equipped with pressure gauge.
The beneficial point of the utility model is: the hydraulic station of the servo motor of this programme is connected with pressure compensation in flowline
Chamber is compensated in test pressure of the pressure that die mould initial stage is stored by pressure compensation chamber to pressure sensor, can be to avoid
The problem of causing servo motor to overload because of the hysteresis quality of pressure transmitting, thus servo motor damage can be effectively prevented.
Detailed description of the invention
Fig. 1 is the hydraulic station schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of pressure compensation chamber in utility model.
Specific embodiment
A kind of hydraulic station of servo motor as shown in Figure 1, 2, including fuel tank 1, servo motor 3, hydraulic pump 2, servo electricity
Machine 3 drives hydraulic pump 2 to work, and the oil inlet of hydraulic pump 2 connects fuel tank 1, and the flowline 4 of hydraulic pump 2 is for the liquid with forming press
Cylinder pressure connection, the flowline 4 of hydraulic pump 2 are equipped with pressure sensor 5, and pressure sensor 5 is for testing 4 pressure of flowline and controlling
Servo motor 3, the flowline 4 are connected with the pressure compensation chamber 7 of tubular, and the pressure compensation chamber 7 includes balance cylinder 701 and storage
Pressure chamber 702, balance cylinder 701 and storage pressure chamber 702 between be equipped with piston section, piston section be equipped with piston 703, balance cylinder 701 with it is fuel-displaced
Pipe 4 is connected to；The storage pressure chamber 702 is equipped with compressed air interface 704.
The pressure compensation chamber 7 is stainless steel cylinder, and stainless steel cylinder is connect by triple valve 6 with flowline 4.Stainless steel
Cylinder uses shoulder hole structure, and the aperture of piston section is greater than the aperture at both ends, so that it is mobile in piston section to limit piston.
The piston section of the pressure compensation chamber 7 is equipped with Double decker piston 703, is equipped with oil emulsion 706 between Double decker piston 703.
Double decker piston and oil emulsion can play good buffer action, prevent oil leak.
The storage pressure chamber 702 of the pressure compensation chamber 7 is equipped with pressure gauge 705.At work, storage is pressed by compressed air interface
Room injecting compressed air, makes storage pressure chamber have scheduled air pressure, and pressure gauge is used to control the air pressure of storage pressure chamber.Carrying out die mould
When, the pressure for storing up pressure chamber pushes piston mobile, can compensate to the pressure of flowline, which can disappear to a certain extent
Except the pressure hysteresis of hydraulic pump, to stablize the power of servo motor, prevent from overloading.
