 Features: 

 1, the overall welding solid structure, so that the body to maintain sufficient rigidity at the same time the most convenient operation; 

 2, the pressure, stroke, dwell time, the closed height can be adjust according to demand, according to the requirements of the design for the two speed (no load pressure slow), can be adjusted using the stroke fast and work into the the length, easy to operate; 
 3, can elect to increase the electronic device or grating and monitor the accurate display of the fuel tank displacement situation, to achieve the required purpose; 4, optional to increase the force sensors and display accurate display of force situation, to achieve the required purpose ; 

 Scope of application: 

 Bow hydraulic machines for metal and nonmetal parts stamping, molding, light stretching, shaping and pressure assembly, rotor, stator press-fit, electronic connectors, electrical parts, press-fit, glasses, clamping and suppression of metal parts and so on; 

 Working principle of the hydraulic press 
 The use of liquid pressure to transfer power and control of a transmission mode. The hydraulic device is composed of the executive body of the hydraulic pump, hydraulic cylinder (hydraulic motor), hydraulic control valves and hydraulic auxiliary components. 
 The hydraulic pump: mechanical energy is converted into hydraulic energy conversion device. 
 Hydraulic cylinder (hydraulic motors and other implementing agencies): hydraulic energy into mechanical energy. 
 Control Valves: Control the flow of hydraulic oil flow, pressure, hydraulic actuator sequence and the protection of the hydraulic circuit of hydraulic machines, of THO role of hydraulic products. Talking about popular control and regulation of the hydraulic medium flow, pressure and flow. To control the movement direction of the executive body, the output force or torque. Velocity. Action sequence, and to restrict and regulate the working pressure of the hydraulic system to prevent overload effect (such as one-way valve, valve, relief valve, pressure reducing valves, sequence valves, throttle valves. Speed ??control valve, etc.) 
 I produced the four-column hydraulic press, Guangdong four-column hydraulic press features: 
 A built-in quick-cylinder, air travel speed, high production efficiency; 
 2, to facilitate manual adjustment of institutions to adjust the pressure head or on the bench in any position in the travel repression, may also adjust the fast-forward and work to process the length of any itineraries; 
 3, the pressure can process the stepless adjustment; 

 Safe operation: 
 A. The operator be familiar with the general properties and structure of the hydraulic press to prohibit the use of overload; 
 Two. Before use, in accordance with the provisions of lubricating oil, check the high-pressure pump, pressure gauge, a variety of valves, seals, etc. is normal; 
 3. Before starting to check the mold supporting material weight to meet the requirements, said the material tool is accurate; 
 4. Touch with oppression must be placed in the position of the plate center, ban eccentric use. Each class before starting the pressure test should be checked once mold is a split loss and abnormal; 
 5 Double operation, set the hand to boot, mutual coordination and cooperation; 
 6. Hands, head placed between the mold and the pressure head is strictly prohibited; 
 7. Work is completed, will pressure products, tools, dies in order and placed in the designated place.
