What is the power press?

A power press is a type of machine used to convert mechanical energy into pressurized fluid. It is often used in industrial settings to apply force to large objects, such as sheets of metal or concrete. power presses can be powered by hydraulic, pneumatic, or electrical systems.

What is the application of press machine?

Presses can be widely used in processes such as cutting, punching, blanking, bending, riveting and forming. Processed into parts by applying intense pressure to a metal blank to cause the metal to plastically deform and fracture.

Universal press for sheet metal stamping, suitable for stamping work such as punching blanking, bending, folding and shallow stretching, used in watches, toys, tableware, telecommunication equipment, instrumentation, motors, electrical appliances, tractors and automobile manufacturing , daily hardware, radio components and other industries have a wide range of applications.

What are the classifications of press machines?

According to the structural form, it is mainly divided into: four-column type, single-column type (C type), horizontal type, frame type, gantry type, universal hydraulic press, etc.

According to the application, it is mainly divided into metal forming, bending, stretching, punching, powder (metal, non-metal) forming, pressing, extrusion, etc.

What are the main components of a press machine?

1. Host

The press machine is mainly composed of an upper beam, a column, an adjusting screw and a hand wheel, a pressure plate, an oil cylinder and a piston. There is a movable ball seat between the end of the screw and the upper platen. When the bottom surface of the upper platen is in contact with the top surface of the test piece during operation, it can automatically adapt to the slight inclination in the height direction of the test piece, so that the two planes are in full contact with each other, so that the test piece Even by force. According to the size of the test piece, the handwheel and lead screw can be turned to properly adjust the test space. The positioning line frame is engraved on the top surface of the lower platen, which is convenient for placing the test piece in the center.

2. Hydraulic system

It is composed of hydraulic pump, oil delivery valve, oil return valve, oil tank, oil filter and oil pipe, etc. The hydraulic pump is an axial five-piston ultra-high pressure pump, which is directly driven by an electric motor. There is a safety valve on the oil delivery valve, which can overflow when overloaded, which plays a safety role. Manipulate the hand wheel of the oil delivery valve to adjust the oil intake of the oil cylinder to achieve the required loading rate. Open the oil return valve to make all the oil in the oil cylinder and the oil pump flow back to the oil tank.

It mainly includes measurement and control system, printer and pressure sensor.

3. Electrical system: It is composed of motor, start button, stop button, AC contactor, fuse and so on.

Now World can supply power press capacity from 6.3ton to 2500ton, C fame and H frame crank press, tie-rod and mono block type eccentric gear press, hydraulic press, hydraulic shearing machine and bending machine (press brake), fiber laser cutting machine and the automatic accessories such as decoiler, straightening machine and roller NC feeder.
