CNC hydraulic press (a kind of hydraulic press) is a special hydraulic oil as a working medium, through the hydraulic pump as a power source, by the force of the pump to make the hydraulic oil through the hydraulic pipeline into the cylinder/piston, and then the cylinder/piston there are several groups of seals with each other, different positions of the seal are different, but all play the role of sealing, so that the hydraulic oil can not leak. Finally, through the check valve, the hydraulic oil is circulated in the tank, and the cylinder/piston is cycled to do work so as to complete a certain mechanical action as a kind of machinery of productivity.


CNC hydraulic press is composed of two parts: main machine and control mechanism. The main part of the CNC hydraulic press includes the body, the master cylinder, the ejector cylinder and the liquid filling device. The power mechanism is composed of oil tank, high pressure pump, low pressure control system, motor and various pressure valves and direction valves. Under the control of the electric device, the power mechanism realizes the energy conversion, adjustment and transmission through the pump and the cylinder and various hydraulic valves to complete the cycle of various process actions.


sort


CNC hydraulic presses are classified according to structural form


CNC hydraulic press is mainly divided into: four-column hydraulic press (three-beam four-column type, five-beam four-column type), double-column hydraulic press, single-column hydraulic press (C-shape structure), frame hydraulic press, etc.


Classified according to the purpose of the hydraulic press


CNC hydraulic press is mainly divided into metal forming hydraulic press, bending hydraulic press, drawing hydraulic press, punching hydraulic press, powder (metal, non-metal) forming hydraulic press, hydraulic press, extrusion hydraulic press, extrusion molding and so on.


peculiarity


CNC hydraulic press pump directly driven hydraulic press has the following characteristics


1. The travel speed of the moving beam of the CNC hydraulic press depends on the amount of liquid provided by the pump, and has nothing to do with the deformation resistance of the forging in the process. If the liquid supply of the pump is constant, the working speed of the hydraulic press is a fixed value.


2, the pump liquid supply pressure and the power consumed are related to the deformation resistance of the workpiece to be processed, the working deformation resistance is large, the pump liquid supply pressure and the power consumed are also large, and the reverse is small.


3, can use the movable beam travel speed constant and pump liquid pressure change characteristics, as a signal to control the distributor, in order to achieve the automatic control of CNC hydraulic press.


4, the basic investment province, small footprint, simple daily maintenance and maintenance. The hydraulic pump in the direct transmission system of the pump is selected according to the maximum working speed and working pressure of the CNC hydraulic press, and the CNC hydraulic press is not fully utilized in the filling stroke, the return journey, the auxiliary process and the required working pressure is small, especially the hydraulic press with large tonnage, and its utilization coefficient is very low. Therefore, CNC hydraulic presses tend to be graded transmission of working speed and working pressure


What is the use of CNC oil press?


CNC hydraulic press is widely used in the automotive industry parts processing and various industries of a variety of products finalize, blanking, correction and shoemaking, handbags, rubber, mold, shaft, shaft sleeve parts of the press assembly, embossing molding, plate parts bending, embossing, sleeve stretching and other processes. Washing machine, motor, automobile motor, air conditioning motor, micro motor, servo motor, wheel manufacturing, shock absorber, motorcycle and machinery industries.


What is the working principle of CNC oil press?


Hydraulic transmission is a transmission mode that uses liquid pressure to transfer power and control. Hydraulic device is composed of hydraulic pump, hydraulic cylinder (hydraulic motor and other actuator), hydraulic control valve and hydraulic auxiliary components


Hydraulic pump: conversion device that converts mechanical energy into hydraulic energy.


Hydraulic cylinder (hydraulic motor and other actuator) : converts hydraulic energy into mechanical energy.


Control valve: control hydraulic oil flow, flow direction, pressure, the working order of the hydraulic actuator and protect the hydraulic circuit. Generally speaking, it is to control and adjust the flow direction, pressure and flow of the hydraulic medium. Thereby controlling the direction of motion of the actuator and the output force or torque. The speed of motion. Action sequence, as well as limit and adjust the working pressure of the hydraulic system, prevent overload and other functions (such as check valves, reversing valves, relief valves, pressure reducing valves, sequence valves, throttle valves. Speed control valve, etc.)


Auxiliary components: 1, oil tank: used to store oil, heat dissipation. Separating air and impurities in oil 2, tubing and tubing connector 3, oil filter 4, pressure gauge 5, sealing element


Numerical control hydraulic press operating rules


1. The operator should be familiar with the general performance and structure of the hydraulic press, and it is forbidden to overload the use.


2. Before use, it should be lubricated and refueling according to the regulations, and check whether the high-pressure pump, pressure gauge, various valves, sealing rings, etc., are normal.


3. Before starting, check whether the mold is matched, whether the material weight meets the requirements, and whether the material tool is accurate.


4. When pressing, the touch must be placed in the center of the plate, and eccentric use is prohibited. Before each shift starts, after the pressure test, the mold should be checked for cracks.


5. When multiple people operate, there should be a special person to boot and coordinate with each other.


6. Do not place the hand or head between the mold and the indenter.


Seven. After the work is finished, the pressed products, tools and molds should be sorted out and placed in the designated place.


CNC oil press maintenance


Operating system


1, CNC oil press personnel should have the corresponding qualifications, must hold a certificate, it is strictly prohibited to open the use of the machine does not understand the personnel.


2, before the shift should wear the provisions of labor protection supplies.


3, check the following before starting: whether the photoelectric protection device is reliable, whether the stroke switch is sensitive, whether the fasteners are loose.


4. Remove the debris on the workbench and mold, adjust the working pressure and slide stroke, run empty for one to two minutes, and everything can work normally.


5, the adjustment handle on the machine has been adjusted properly at the factory, and non-debugging personnel can not be adjusted at will


Maintenance system


1, according to the lubrication requirements of the machine lubrication maintenance.


2. After each year of work, the hydraulic oil should be released from the bed oil tank to clean the oil tank, and the filtered hydraulic oil should be re-filled, and the oil amount should be determined at the 3/4 height of the oil target.


3. The oil filter net on the suction pipe must be cleaned or washed regularly.


4. Check whether the handle, twist and button are damaged regularly.


5, the motor must be kept clean, the motor air intake screen cover should always maintain good ventilation, can not be blocked.


6, 10 minutes before work every day, the machine oil lubrication and scrub clean machine.


7, it is strictly prohibited for non-operators to operate the equipment, and it must be stopped when people leave the machine.
