What is a three-beam and four-column hydraulic press?
The three-beam and four-column hydraulic press is a common hydraulic mechanical equipment that is widely used in metal forming, stamping, press-fitting and other industrial fields. Its name comes from its structural characteristics - it is composed of "three beams" (upper beam, movable beam, lower beam) and "four columns" (four upright columns). This article will introduce in detail the structure, working principle, application scenarios and popular models of the three-beam and four-column hydraulic press.
1. Structure of three-beam and four-column hydraulic press
The three-beam and four-column hydraulic press mainly consists of the following core components:
| Part name | Function description |
|---|---|
| upper beam | Fixed hydraulic cylinder and guide device to bear the main pressure |
| Movable beam | Connect the mold and move up and down to complete the processing |
| lower beam | Fixed workbench to support the overall structure |
| four pillars | Connect the upper and lower beams to provide stable support and guidance |
| Hydraulic system | Including oil pumps, control valves, oil cylinders, etc., providing power |
2. Working principle of three-beam and four-column hydraulic press
The working principle of the three-beam and four-column hydraulic press is based on Pascal's law, which realizes power conversion by transmitting pressure through hydraulic oil:
| working stage | Action description |
|---|---|
| filling stage | The oil pump sends hydraulic oil into the oil cylinder, and the movable beam moves down quickly |
| pressurization phase | The system pressure increases and the movable beam exerts working pressure on the workpiece. |
| Holding stage | Maintain constant pressure to ensure molding quality |
| return phase | The hydraulic oil returns to the tank and the movable beam rises and resets. |
3. Application fields of three-beam and four-column hydraulic press
This type of hydraulic press is widely used in many industries due to its stable structure, high pressure, and high precision:
| Application industry | Specific use | Typical pressure range |
|---|---|---|
| automobile manufacturing | Car body parts stamping, parts pressing | 100-5000 tons |
| Home appliance production | Metal shell molding, compressor assembly | 50-1000 tons |
| Aerospace | Titanium alloy sheet forming | 500-8000 tons |
| building materials | Artificial stone slab pressing | 200-3000 tons |
