什么是液壓機，液壓機的用途

液壓機是一種以液體為工作介質，根據帕斯卡原理制成的用于傳遞能量以實現各種工藝的機器。液壓機一般由本機（主機）、動力系統及液壓控制系統三部分組成。液壓機分類有閥門液壓機，液體液壓機，工程液壓機。

液壓機簡介

液壓機（又名：油壓機）液壓機是一種利用液體靜壓力來加工金屬、塑料、橡膠、木材、粉末等制品的機械。它常用于壓制工藝和壓制成形工藝，如：鍛壓、沖壓、冷擠、校直、彎曲、翻邊、薄板拉深、粉末冶金、壓裝等等。

它的原理是利用帕斯卡定律制成的利用液體壓強傳動的機械，種類很多。當然，用途也根

據需要是多種多樣的。如按傳遞壓強的液體種類來分，有油壓機和水壓機兩大類。

水壓機產生的總壓力較大，常用于鍛造和沖壓。鍛造水壓機又分為模鍛水壓機和自由鍛水壓機兩種。模鍛水壓機要用模具，而自由鍛水壓機不用模具。我國制造的第一臺萬噸水壓機就是自由鍛造水壓機。

液壓機用途

液壓機是一種以液體為工作介質，用來傳遞能量以實現各種工藝的機器。液壓機除用于鍛壓成形外，也可用于矯正、壓裝、打包、壓塊和壓板等。液壓機包括水壓機和油壓機。以水基液體為工作介質的稱為水壓機,以油為工作介質的稱為油壓機。液壓機的規格一般用公稱工作力（千牛）或公稱噸位（噸）表示。鍛造用液壓機多是水壓機，噸位較高。為減小設備尺寸，大型鍛造水壓機常用較高壓強（35兆帕左右），有時也采用 100兆帕以上的超高壓。其他用途的液壓機一般采用 6～25兆帕的工作壓強。油壓機的噸位比水壓機低。

本設備特別適合于中心載荷零件的彎曲、成型、翻邊等多種工藝，配上沖裁緩沖裝置后，還可以用于沖孔，落料加工，是船舶行業、壓力容器行業、化工等行業的首選產品。

用于金屬薄板零件的拉伸成型、翻遍、彎曲和沖壓等工藝，也可用于一般的壓制工藝，可根據用戶需要增加沖裁緩沖、打料、移動工作臺等裝置。

除了用于鍛壓成形外，三梁四柱液壓機也可用于矯正、壓裝、打包、壓塊和壓板等。

還可用于軸類零件的壓制工藝，型材的校準、扣壓、壓裝工藝以及板材零件的彎曲、爭辯、定型、壓印、套型、拉伸、可塑性材料的壓制工藝，如沖壓、彎曲、翻邊薄拉伸等作業，也可以從事校正、壓裝、塑料制品及粉末制品的壓制成型作業。因其應用范圍廣泛也被稱為萬能液壓機.

Hydraulic press is a kind of machine which uses liquid as working medium and is made according to Pascal principle to transfer energy to realize various processes. The hydraulic press is generally composed of this machine (host), power system and hydraulic control system. Hydraulic press classification has valve hydraulic press, liquid hydraulic press, engineering hydraulic press.

Introduction to hydraulic press

Hydraulic press (also known as: Hydraulic Press) hydraulic press is a kind of machine which uses hydrostatic pressure to process metal, plastic, rubber, wood, powder and other products. It is commonly used in pressing process and pressing forming process, such as forging, stamping, cold extrusion, straightening, bending, flanging, sheet metal drawing, powder metallurgy, press fitting and so on.

Its principle is to use Pascal's law to make use of liquid pressure transmission machinery, many kinds. Of course, the use is fundamental

There are many kinds of things that need to be done. For example, according to the type of liquid transmission pressure, there are two major types of oil press and hydraulic press.

The total pressure produced by hydraulic press is large, which is often used for forging and stamping. Forging hydraulic press is divided into die forging hydraulic press and free forging hydraulic press. Die forging hydraulic press should use die, while free forging hydraulic press does not need die. The first 10000 ton hydraulic press made in China is a free forging hydraulic press.

Application of hydraulic press

Hydraulic press is a kind of machine which uses liquid as working medium to transfer energy to realize various processes. Hydraulic press is not only used for forging forming, but also for straightening, pressing, packing, pressing block and pressing plate. Hydraulic press includes hydraulic press and hydraulic press. The water-based liquid as the working medium is called the hydraulic press, and the one with oil as the working medium is called the hydraulic press. The specification of hydraulic press is generally expressed by nominal working force (KN) or nominal tonnage (ton). Forging hydraulic press is mostly hydraulic press with high tonnage. In order to reduce the size of the equipment, high pressure (about 35 MPa) is often used in large forging hydraulic press, and sometimes the ultra-high pressure above 100 MPa is used. The working pressure of hydraulic press for other purposes is 6 ~ 25 MPa. The tonnage of hydraulic press is lower than that of hydraulic press.

This equipment is especially suitable for bending, forming, flanging and other processes of center load parts. Equipped with blanking buffer device, it can also be used for punching and blanking. It is the first choice for shipbuilding industry, pressure vessel industry and chemical industry.

It can be used for drawing forming, turning over, bending and stamping of sheet metal parts, and can also be used for general pressing process. It can also be used for blanking buffer, punching, moving table and other devices according to the needs of users.

In addition to forging, the three beam and four column hydraulic press can also be used for correction, press fitting, packing, pressing block and pressing plate.

It can also be used for the pressing process of shaft parts, profile calibration, crimping, press mounting, bending, shaping, embossing, nesting, stretching and plastic material pressing process of plate parts, such as stamping, bending, flanging and thin stretching, and also can be used for the pressing and forming operations of alignment, pressing, plastic products and powder products. Because of its wide range of applications, it is also known as universal hydraulic press
