Working Principle of single column hydraulic press

Single column hydraulic press, body for c-type single arm structure

1. Welding by submerged arc welding, vibration treatment after welding, to ensure that the fuselage is not deformed.  

2. The body adopts QT450 nodular cast iron, high temperature treatment, stress relief annealing, normalizing, natural aging treatment to eliminate internal stress, ensure the cast iron performance, prevent casting deformation and damage.  

The series press is equipped with independent hydraulic and electrical control system, centralized control by button, can realize two kinds of molding process of constant process and constant pressure, with pressure display and stroke, pressure adjustment and other functions.  And the series with four pillar guide column guide, so as to improve the accuracy of the product, and the column, the piston rod after quenching copper plating and hard chromium, to ensure the wear resistance and high roughness of the surface, the oil pump inlet is equipped with a unique filter device, to ensure the service life of the oil pump and valve.  Imported high-pressure hose for oil connection greatly reduces machine noise.  In addition, according to user requirements, other imported PLC, grating protection and man-machine interface (touch screen) and other advanced components.  For the special requirements of customers, we can specially design production, maximum to meet the requirements of customer production technology.

The characteristics of single column hydraulic press machine 

1. It has the characteristics of good rigidity, good guiding performance and fast speed.  

2. Convenient manual adjustment mechanism can adjust the pressure head or the upper table in the stroke of any position pressing, can also be arbitrarily adjusted in the design of the stroke of fast forward and the length of the work process.  

3. The solid open welded structure enables the fuselage to maintain sufficient rigidity while having the most convenient operation space.  

4. The overall casting of the fuselage has the advantages of strong deformation resistance, high working accuracy and long service life, which is suitable for products with higher requirements

The working principle of single column hydraulic press machine 

Hydraulic press machine is the use of liquid to transfer pressure equipment.  Liquids obey PASCAL's law when they transfer pressure in a closed container.  

The hydraulic transmission system of hydraulic press consists of power mechanism, control mechanism, executive mechanism, auxiliary mechanism and working medium.  

The power mechanism usually uses the oil pump as the power mechanism, generally for the positive displacement oil pump.  In order to meet the requirements of the motion speed of the actuator, one or more oil pumps are selected.  Gear pump for low pressure (oil pressure less than 2.5MP);  Vane pump for medium pressure (oil pressure less than 6.3MP);  High pressure (oil pressure less than 32.0MP) for piston pump.  

Hydraulic press is usually refers to the hydraulic pump and hydraulic motor, hydraulic pump and hydraulic motor are energy conversion device in the hydraulic system, the difference is the hydraulic pump drive motor can convert the mechanical energy of the oil pressure, is the power unit in the hydraulic system, the hydraulic motor is the oil pressure can be converted into mechanical energy, is executive device in the hydraulic system.  

The hydraulic pump and hydraulic motor commonly used in the hydraulic system are volumetric, its working principle is to use the change of sealing volume for oil suction and pressure.  From the working principle, most of the hydraulic pump and hydraulic motor is reciprocal, that is, the input pressure oil, hydraulic pump becomes hydraulic motor, can output speed and torque, but in the structure, hydraulic pump and hydraulic motor or some differences

Single column hydraulic press has independent power organization and electrical system, adopts the centralized control buttons, which can realize the adjustment, manual and semi-automatic three works the machine working pressure, pressing speed, no-load fast descending and slow journey and scope, all may be adjusted according to the requirements of the process, and can finish the ejection process can take out, stretching process three kinds of way,  Each process and constant pressure, two kinds of process action for choice, constant pressure molding process after pressing with ejection delay and automatic return.  Single column hydraulic press has a wide range of versatility, suitable for all kinds of plastic material processing and forming, such as extrusion, bending, folding, stretching, etc., at the same time, hydraulic press can also be used for all kinds of plastic, powder products pressing forming.  In addition, the single column hydraulic press can also be used for product calibration, pressing and shaping
