Working Principle and Applications of a 300-ton Four-column Hydraulic Press

The core principle of a 300-ton four-column hydraulic press is to utilize hydraulic transmission and Pascal's law to convert electrical energy into stable, precisely controlled, and immense mechanical pressure. Its four-column structure provides unparalleled rigidity and stability. Below, the editors of Jianlong Hydraulic Technology share the features and advantages of the 300-ton four-column single-press hydraulic press for your reference!

1. Working Principle

1.1 Rapid Downstroke: The motor starts, the oil pump supplies oil, and the main cylinder piston rapidly descends under its own weight and oil pressure.

1.2 Slow Pressurization: When the upper die contacts the workpiece, the system pressure increases, transitioning to a slow, high-pressure stroke to apply pressure to the workpiece.

1.3 Holding Pressure: After reaching the set pressure, the system stops supplying oil and maintains pressure for a period of time to allow the material to fully deform.

1.4 Pressure Relief Return Stroke: After the holding stroke ends, the main cylinder releases pressure, and oil enters the lower chamber, pushing the movable crossbar rapidly back to its initial position. 1.5 Workpiece Ejection (Optional): The ejection cylinder (optional) under the worktable operates to eject the formed workpiece from the lower die.

2. Main Applications

Due to its strong versatility, the 300-ton four-column hydraulic press is used in:

2.1 Metal Forming: Sheet metal stretching, bending, flanging, cold extrusion, and coining.

2.2 Powder Metallurgy: Compression molding of metal powders, ceramic powders, and magnetic materials.

2.3 Plastic Products: Compression molding of SMC/BMC fiberglass reinforced plastics and rubber products.

2.4 Alignment and Pressing: Alignment of parts such as shafts and connecting rods, and press fitting of bearings and bushings.

2.5 Refractory Materials: Compression molding of refractory bricks and magnesia carbon bricks.

2.6 Automotive Parts: Stamping and forming of engine mounts, shock absorbers, etc.

2.7 Laboratory: Used for material testing, scientific research, and other experiments.

The 300-ton four-column single-press hydraulic press is a truly universal machine. By simply replacing different molds, it can be used for everything from metal plastic processing to non-metallic material forming. It serves a wide range of industries, from automotive and home appliance production to powder metallurgy and composite materials, making it an indispensable key piece of equipment in modern industrial production.
