What is a four-column hydraulic press
In industrial production, four-column hydraulic press is a common pressure processing equipment, which is widely used in metal molding, plastic product pressing, powder metallurgy and other fields. This article will introduce in detail the definition, structure, working principle, application scenario of the four-column hydraulic press, as well as the popular topics and hot content in the past 10 days.
1. Definition of four-column hydraulic press
The four-column hydraulic press is a mechanical device that uses hydraulic systems to generate high pressure. Its core feature is that it uses four columns as a support structure to ensure the stability and accuracy of the equipment under high-pressure working state. It presses oil into the cylinder through a hydraulic pump, pushing the piston to move, thereby achieving pressing or forming the workpiece.
2. Structure of four-column hydraulic press
The main structure of the four-column hydraulic press includes the following parts:
| Part Name | Function description |
|---|---|
| Hydraulic system | Including hydraulic pumps, oil cylinders, control valves, etc., it is responsible for providing power and controlling pressure. |
| Four pillars | Support the entire equipment to ensure the stability and verticality of the workbench. |
| Workbench | Used to place workpieces, usually with adjustable height. |
| Control system | Automatic operation is achieved by controlling the operation of the hydraulic press through electrical or PLC. |
Working principle of three and four column hydraulic press
The working principle of the four-column hydraulic press is based on Pascal's law, that is, the pressure of liquid in the closed container can be uniformly transmitted. The specific workflow is as follows:
1. The hydraulic pump pulls the oil out of the oil tank and presses it into the oil cylinder through the control valve.
2. The piston in the oil cylinder moves downward under the action of oil pressure to apply pressure to the workpiece.
3. After the pressing is completed, the control valve switches the oil circuit and the piston returns to the initial position under the action of the return oil cylinder.
Application scenarios of four-column hydraulic press
Four-column hydraulic presses are widely used in the following fields due to their high pressure, high precision and stability:
| Application areas | Specific use |
|---|---|
| Metal forming | Used for metal processing technology such as stamping, stretching, bending, etc. |
| Plastic products | Pressed plastic sheets, molded plastic parts, etc. |
| Powder metallurgy | The metal powder is pressed into molding and used to make gears, bearings, etc. |
| Rubber products | Used for vulcanized rubber, pressed rubber pads, etc. |
