Introduction to 1000 ton hydraulic press

A 1000 ton hydraulic press (also known as a hydraulic press) is a machine that uses hydrostatic pressure to process products such as metal, plastic, rubber, wood, and powder. It is commonly used in pressing and forming processes, such as forging, stamping, cold extrusion, straightening, bending, flanging, thin plate deep drawing, powder metallurgy, press fitting, and so on.
Its principle is to use Pascal's law to create a mechanical device that utilizes liquid pressure transmission, and there are many types. Of course, the uses are also diverse according to needs. According to the type of liquid that transmits pressure, there are two main categories: hydraulic presses and hydraulic presses.
The total pressure generated by a hydraulic press is relatively high and is commonly used for forging and stamping. Forging hydraulic presses are divided into two types: forging hydraulic presses and free forging hydraulic presses. Die forging hydraulic presses require molds, while free forging hydraulic presses do not require molds. The top 10000 ton Maotai hydraulic press manufactured in China is the free forging hydraulic press.

The purpose of a 1000 ton hydraulic press
A 1000 ton hydraulic press is a machine that uses liquid as the working medium to transfer energy and achieve various processes. Hydraulic presses can be used not only for forging and forming, but also for straightening, pressing, packaging, pressing blocks, and pressing plates. Hydraulic presses include hydraulic presses and hydraulic presses. A hydraulic press is called one that uses water-based liquid as the working medium, and one that uses oil as the working medium is called a hydraulic press. The specifications of hydraulic presses are generally expressed in nominal working force (kilonewtons) or nominal tonnage (tons). Most hydraulic presses used for forging are hydraulic presses with high tonnage. To reduce equipment size, large forging hydraulic presses commonly use higher pressures (around 35 megapascals), and sometimes even use ultra-high pressures above 100 megapascals. Hydraulic presses for other purposes generally use a working pressure of 6-25 megapascals. The tonnage of hydraulic press is lower than that of hydraulic press.


The working principle of a 1000 ton hydraulic press

The areas of the large and small plunger are S2 and S1, respectively, and the forces acting on the plunger are F2 and F1, respectively. According to Pascal's principle, the pressure of a sealed liquid is equal everywhere, that is, F2/S2=F1/S1=p; F2=F1(S2/S1)。 The gain effect of hydraulic pressure is the same as mechanical gain, where the force increases but the work does not increase. Therefore, the movement distance of the large plunger is S1/S2 times that of the small plunger.
The basic principle is that the oil pump delivers hydraulic oil to the integrated plug-in valve block, and distributes the hydraulic oil to the upper or lower chamber of the cylinder through various one-way valves and relief valves. Under the action of high-pressure oil, the cylinder moves A hydraulic press is a device that uses liquid to transmit pressure. When a liquid transfers pressure in a closed container, it follows Pascal's law. The hydraulic transmission system of a four column hydraulic press consists of a power mechanism, a control mechanism, an actuator, an auxiliary mechanism, and a working medium. The power mechanism usually uses an oil pump as the power mechanism, usually an integral oil pump. To meet the requirements of the actuator's movement speed, one or multiple oil pumps should be selected. Gear pump for low pressure (oil pressure less than 2.5MP); Medium pressure (oil pressure less than 6.3MP) blade pump; Use a plunger pump for high pressure (oil pressure less than 32.0MP). The pressure processing and forming of various plastic materials, such as extrusion, bending, deep drawing of stainless steel plates and cold pressing of metal parts, can also be used for the pressing of powder products, grinding wheels, glued laminated wood, and thermosetting resin products.


Classification of 1000 ton hydraulic press

According to the structural form, it is mainly divided into four column, single column (C-type), horizontal, vertical frame, hydraulic press, etc.
It is mainly divided into metal forming, bending, stretching, punching, powder (metal, non-metal) forming, pressing, extrusion, etc. according to its purpose.
Hot forging hydraulic press
Large forging hydraulic press is a forging equipment that can complete various free forging processes and is one of the widely used equipment in the forging industry. At present, there are forging hydraulic presses with series specifications such as 800T, 1600T, 2000T, 2500T, 3150T, 4000T, 5000T, etc.
four-column hydraulic press
This hydraulic press is suitable for the pressing process of plastic materials. Such processes as powder product molding, plastic product molding, cold (hot) extrusion metal molding, sheet stretching, as well as horizontal pressing, bending pressing, flipping, and correction.
The four column hydraulic press can be divided into four column two beam hydraulic press, four column three beam hydraulic press, four column four beam hydraulic press, etc.
Single arm hydraulic press (single column hydraulic press)
Expandable working range, utilizing three sided space, extending the stroke of the hydraulic cylinder (optional), with a large expandable range of 260mm-800mm, and can preset working pressure; Hydraulic system cooling device.
Longmen hydraulic press
It can perform assembly, disassembly, straightening, rolling, stretching, bending, punching and other tasks on machine components, truly achieving multi-purpose use of one machine. The workbench of this machine can move up and down, and its size expands the opening and closing height of the machine, making it more convenient to use.
Double column hydraulic press
This series of products is suitable for pressing, bending, shaping, embossing, flanging, punching, and shallow stretching of various components; Processing techniques for forming metal powder products. Adopting electric control, equipped with jog and semi-automatic cycle, it can maintain pressure delay, and has good slider guidance. It is easy to operate, maintain, economical and durable. According to user needs, thermal instruments, ejector cylinders, stroke digital displays, counting and other functions can be added.

Scope of application of hydraulic press
Hydraulic forming technology has a wide range of applications in industries such as automobiles, aviation, aerospace, and pipelines. It is mainly suitable for hollow structural parts with circular, rectangular, or irregular cross-sections that vary along the axis of the component, such as irregular pipe fittings in the exhaust system of automobiles; Non circular cross-section hollow frames, such as engine mounts, dashboard brackets, and body frames (accounting for approximately 11% to 15% of the vehicle's mass); Hollow shaft components and complex pipe fittings, etc. Figure 2 shows some typical parts manufactured by hydraulic forming technology applied in the automotive industry.
The applicable materials for hydraulic forming process include carbon steel, stainless steel, aluminum alloy, copper alloy, nickel alloy, etc. In principle, materials suitable for cold forming are all suitable for hydraulic forming process.
