What is the function of the four-column hydraulic press

Tensile four-column hydraulic press is a kind of equipment specially used for drawing, stamping and forming sheet metal, which is widely used in automotive manufacturing, aerospace, home appliances, construction and machinery manufacturing. Its main function is to apply strong pressure through the hydraulic system to make the metal sheet form complex shapes and structures in the mold. The following are the main functions and applications of the tensile four-column hydraulic press:

Main function 1. Metal stretching: Stretch sheet metal to the desired shape and size. For example, the forming of car body panels, fuel tanks, washing machine shells and other components.

2. Stamping: Through the combination of punch and die, the metal plate is punched, cut and formed. For example, making metal doors, window frames and other building components.

3. Bending: Bend the sheet metal into a specific Angle and shape. For example, manufacturing pipes, brackets and frames.

4. Extrusion molding: The metal material is extruded into a specific cross-section shape by high pressure. For example, the production of aluminum profiles and steel pipes.

5. Press assembly: The different parts are assembled together by pressure. For example, bearing pressing and component assembly.

Component 1. Hydraulic system: Provide the required pressure source, including hydraulic pump, hydraulic cylinder, oil tank and piping system.

2. Four-column frame: composed of four solid columns and upper and lower beams to provide stable structural support and guidance.

3. Workbench: The area where molds and workpieces are placed, usually the height can be moved and adjusted.

4. Mold: according to the need to shape the workpiece design, installed between the upper and lower workbench.

5. Control system: including electrical control cabinet, buttons, display screen, etc., used to control the working process and parameter Settings of the hydraulic press.

Application example 1. Automobile manufacturing: - Body panel: The metal sheet is stretched into complex shaped parts such as car doors, hoods and roofs using a four-column hydraulic press.

Chassis parts: Forming various structural parts of the automobile chassis, such as beams, brackets, etc.

2. Home appliance manufacturing: - Home appliance shell: such as refrigerator, washing machine, air conditioning shell, etc., through hydraulic stretching molding to ensure beautiful appearance and accurate size.

3. Aerospace: - Aircraft parts: The manufacture of aircraft fuselages, wings and other complex shaped structural parts requires high strength and precision.

4. Construction industry: - Metal components: such as door and window frames, curtain wall structures, etc., through hydraulic stamping and tensile molding to ensure quality and beauty.

5. Mechanical manufacturing: - Parts forming ** : Manufacturing parts of various mechanical equipment, such as gear boxes, machine tool bases, etc., through precision drawing and stamping processing.
