What Are the Different Types of Hydraulic Compressors?
Press is the abbreviation of press, hydraulic press and hydraulic press. Press refers to a molding machine used for industrial products through pressure forming. Generally, hydraulic cylinders are used, so it is also called hydraulic press. In the building materials industry, the press is an abbreviation for brick press, which is divided into manual brick press and automatic hydraulic brick press.
- The press is the main equipment for compression molding. It is divided into a frame structure and a column structure according to the frame structure. According to the location of the main oil pressure cylinder, the presses are divided into upper pressure type and lower pressure type. For pressing large plastic laminates, the lower pressure type oil cylinder can be used. For general plastic parts, upper pressure type presses are often used. According to the type of working fluid, it can be divided into hydraulic press driven by hydraulic oil and hydraulic press driven by oil-water emulsion.
- Specially for composite lightweight panels (such as various honeycomb sandwich panels), polyurethane insulation panels, bulletproof armored panels, glass fiber reinforced plastic panels, glass
Press -up hydraulic press
- The working cylinder of the press is placed above the press, the piston of the cylinder moves from top to bottom, and the lower template is fixed. The male and female molds of the mold can be fixed on the upper and lower mold plates, respectively, and the mold can be opened and closed by lifting the upper mold plate. Because the oil cylinder is placed above the press, the workbench is fixed, and the charging can be performed on the workbench, which is convenient to operate and easy to achieve rapid downward movement. Up-press hydraulic presses are widely used, and our country's production of plastic hydraulic presses is basically this type.
Press hydraulic press
- The working oil cylinder of the press is placed under the press, and the piston of the oil cylinder pushes the movable beam to rise to realize the pressure on the mold. The lower pressure hydraulic press has a lower center of gravity and good stability. The oil cylinder is placed at the lower part of the fuselage, and the product can avoid pollution due to oil leakage. Laminated plastics generally use a down-press hydraulic press. The main parameters of the press are the nominal pressure, plunger diameter, platen size and working stroke. The nominal pressure of the hydraulic press is the main parameter that indicates the pressing capacity of the press, and is generally used to indicate the specifications of the press. [3]
