The single-column hydraulic press is a compact and versatile machine. It is designed for stretching, forming, and pressing metal products. It also works well for powder metallurgy, shaft part correction, and sleeve part pressing. The hydraulic system integrates within the machine body. This gives the press a sleek design and makes it easy to operate.
The press offers two main forming processes: fixed stroke and fixed pressure. Operators can adjust these processes based on production needs. The press also includes pressure and stroke displays. These features improve control and efficiency.
The press has an independent hydraulic and electrical control system. It operates through centralized button control, making it easy to use. To enhance accuracy, a four-column guide column is installed. The piston rods are copper-plated and hard-chromium-plated after quenching. This ensures superior wear resistance. The press includes a unique filtering device at the oil pump inlet. This extends the lifespan of the pump and valves. High-pressure hoses reduce operational noise. For customers with specific needs, we offer custom designs. These can include advanced components such as PLCs, grating protection, and human-machine interfaces.
This press is ideal for various applications. It works well for shaft and profile correction, pressing shaft sleeves, bending, embossing, and forming simple sheet parts. It also presses powder and plastic products. As a result, this hydraulic press is used in many industries. These include machine tools, internal combustion engines, automotive motors, electrical appliances, and military enterprises.
Hydraulic Press Working Medium
The working medium in the single-column hydraulic press ensures smooth and reliable operation. The hydraulic fluid needs to have appropriate fluidity and low compressibility. It also needs excellent lubrication and rust prevention capabilities. Initially, hydraulic presses used water as the working medium. Later, manufacturers switched to mineral oil. Oil provides better lubrication, corrosion resistance, and moderate viscosity. These improvements enhanced the press’s performance.
Recently, a new water-based emulsion, “oil-in-water,” has emerged. It combines the lubricity and corrosion resistance of oil. It also has minimal oil content and is less flammable. However, the higher cost of this emulsion limits its use.
Working Principle
Hydraulic presses follow Pascal’s Law. This law states that pressure applied to a confined liquid is transmitted equally in all directions. The hydraulic system of the press consists of several components. These include the power mechanism, control mechanism, actuator, auxiliary components, and the working medium.
Typically, the power mechanism includes a positive displacement oil pump. This pump converts mechanical energy into pressure energy. Different pumps are used based on pressure requirements. Gear pumps are used for low pressure, vane pumps for medium pressure, and plunger pumps for high pressure.
The press operates in three modes: adjustment, manual, and semi-automatic. These modes offer flexibility in adjusting pressure, speed, and stroke range. This versatility enables the press to handle various processes. These include extrusion, bending, stretching, and pressing.
Single-Column vs. Four-Column Hydraulic Press
Both single-column and four-column hydraulic presses serve similar functions. However, they differ in structure and application. The single-column press has a C-type structure with a single vertical column. This makes it more compact and ideal for shaft correction and pressing small parts.
The four-column press has a larger working table. It is better suited for heavy-duty applications such as metal stamping, bending, and stretching. The four-column press is also larger and more expensive. It offers more robust capabilities for complex tasks.
The single-column press is compact, easier to operate, and more affordable. The four-column press typically operates using handles or foot pedals. In contrast, the single-column press operates through centralized button control.
