Hydraulic Power Press Machine

A Hydraulic Power Press Machine is a machine press using a hydraulic cylinder to generate a compressive force. It is a kind of special machining equipment which bases on PASCA's principle and uses the liquid as a working medium to transfer energy to obtain compressive force to shape different types of materials.

Hydraulic power press machine uses the hydraulic equivalent of a mechanical lever and consists of a cylinder fitted with a sliding piston that exerts a force upon a confined liquid, which, in turn, produces a compressive force upon a stationary anvil or baseplate. So various techniques can realize. Within a hydraulic press machine, there is a plate where the sample is placed to be pressed for sample preparation. 

Hydraulic press machine is often used in pressing and pressing forming processes, such as forging press, stamping, cold extrusion, straightening, bending, flanging, sheet drawing, powder metallurgy, pressing, etc. As a professional hydraulic press machine manufacturer and hydraulic press company, Zhongrui has a variety of hydraulic press machine for sale designed to support sheet metal machining requirements. These are compact in size and ideal to work with metal sheets of different metals.

Hydraulic Power Press Machine helps in converting metals sheets to different shapes with fewer possibilities of wastage or damages to metal sheets. It is also a better alternative option of bending or shaping sheets of metals than conventional or manual shaping process. There are many features that make our industrial hydraulic press remain versatile among the compact range of sheet metal equipment.

As a professional power press machine manufacturer, Zhongrui's hydraulic presses are ideal for assembly, straightening, fabrication, quality control, maintenance, product testing, bending, forming, punching and shearing. Every hydraulic power press has a frame that is constructed of heavy-duty arc-welded steel and seamless steel cylinders to prevent leaks.

● Through the operation panels selection, not only can achieve constant stroke, constant pressure 2 molding process, but also to achieve. with pad, no pad, ejection there process working cycle

● The Slider could be adjustable :slide operating pressure, fast down idle stroke, slow pressing strok

● Cartridge valve equipped for hydraulic control system ,reliable ,durable and less hydraulic shock ,shorter connection pipeline and fewer release points, hydraulic integrated system is adopted separate control unit

Hydraulic Power Press Machine Principle

Pascal’s law states that when pressure is applied to a confined fluid, the pressure change occurs throughout the entire fluid. The hydraulic press machine for sale depends on Pascal's principle - the pressure throughout a closed system is constant. 

A Hydraulic Power Press Machine consists of basic components used in a hydraulic system that includes the cylinder, pistons, hydraulic pipes, etc. The working of this press is very simple and the system comprises of two cylinders. One part of the system is a piston acting as a pump, with a modest mechanical force acting on a small cross-sectional area; the other part is a piston with a larger area which generates a correspondingly large mechanical force. 

The piston in the small cylinder is pushed so that it compresses the fluid in it that flows through a pipe into the larger cylinder. The larger cylinder is known as the master cylinder. The pressure is exerted on the larger cylinder and the piston in the master cylinder pushes the fluid back to the small cylinder.

Types of Hydraulic Press Machine

● Horizontal power press machine

The horizontal power press parts can be assembled, disassembled, straightened, compressed, stretched, bent, punched, etc to realize one machine with multi-purpose. The working table of this machine can move up and down, the size expands the opening and closing height of the machine, making it more convenient to use.

● Vertical frame hydraulic power press machine

Vertical frame hydraulic press mainly used to compress and pack the relaxed goods such as cotton, yarn, cloth, hemp, wool, and other products. The compressed package block has the uniform outer dimension and the large density and proportion, which is suitable for container transportation.

● Four-column hydraulic power press machine

The four-column hydraulic press can be divided into the four-column two-beam hydraulic press, four-column three-beam hydraulic press, and four-column four-beam hydraulic press.

The four pillars hydraulic press machine for sale is suitable for pressing the plastic material, like powder products forming, plastic products forming, cold (hot) extrusion metal forming, sheet drawing, transverse pressing, bending, penetration, and correction processes.

● C- frame power press

This industrial hydraulic press has a 'C' like shape, which is specifically designed to maximize the floor space for the workers in order to move around easily at the workplace. Unlike other presses that have multi-processes, the C- frame presses only include a single press application. The C- frame power press machine's application includes straightening, drawing and mostly includes assembling work.  The C- frame presses are also available with extra features such as wheel stands and pressure gauges. C- frame presses come in a variety of weights.


Advantages of Hydraulic Power Press Machine

● A Wide Range of Designs

There are many different types of hydraulic power press machines suitable for different applications. Some of the different types of presses are; Vertical H-frame style, C-frame presses, Horizontal presses, Movable table presses, Tire presses, Movable frame presses, and Lab presses. Each design is also available with single or double-acting work heads, and manual, air or electric operation. 

● Smooth Pressing 

Hydraulics give you smooth, even pressure throughout the ram stroke. This allows tonnage to be achieved at any point of the ram travel, unlike mechanical presses where you only get the tonnage is at the bottom of the stroke.

● Pressure Control

Many hydraulic press machines for sale have pressure relief valves available. You can dial in whatever pressure you require and the press will repeat that preset pressure consistently taking the guesswork out of the equation of too much or too little pressure.

● Lifting and Pressing Ability

Many hydraulic press machines for sale feature double-acting cylinders which means you have lifting force as well as pressing forces. Any tooling attached to the ram can easily be raised with the double-acting cylinder.

● Reduce weight and save materials

Hydroforming is an advanced manufacturing technology for realizing a lightweight structure. Compared with the traditional stamping process, the hydroforming process has obvious advantages over reducing the weight of products. For typical parts such as automobile engine bracket and radiator bracket, hydraulic forming parts are 20% - 40% lighter than stamping parts. For hollow step shaft parts, the weight can be reduced by 40% - 50%. In the automotive industry, aviation, aerospace fields, it is a long-term goal to reduce the structural quality and save energy in operation.
