沖壓機和液壓機的區別與不同特點

液壓機：液壓機是一種以液體為工作介質，利用液體來傳遞壓力以實現各種工藝的機器。

沖壓機：沖壓機也叫沖床，主要用作鈑金零件的加工。

二者的區別還是很多的，具體如下

原理上：

液壓機是油泵把液壓油輸送到集成插裝閥塊，通過各個單向閥和溢流閥把液壓油分配到油缸的上腔或者下腔，在高壓油的作用下，使油缸進行運動。

沖壓機是通過電動機驅動飛輪，并通過離合器，傳動齒輪帶動曲柄連桿zhidao機構使滑塊上下運動，帶動拉伸模具對鋼板成型。

用途上：

液壓機適合于中心回載荷零件的彎曲、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。沖壓機主要用作鈑金零件的加工。

分類

液壓機分類

液壓機可分為熱鍛液壓機，四柱液壓機，單臂液壓機，龍門式液壓機，雙柱液壓機

沖壓機分類：

按滑塊驅動力分機械式沖床 ，液壓式沖床

依滑塊運動方式分單動，復動，多動

依滑塊驅動結構分曲軸式沖床 ，無曲軸式沖床，肘節式沖床，摩擦式沖床，螺旋式沖床 ，齒答條式沖床，連桿式沖床，凸輪式沖床

Hydraulic press: hydraulic press is a kind of machine which uses liquid as working medium to transfer pressure to realize various processes.

Stamping machine: also known as punch press, mainly used for sheet metal parts processing.

There are many differences between them, as follows

In principle:

The hydraulic press is an oil pump to transport the hydraulic oil to the integrated cartridge valve block. The hydraulic oil is distributed to the upper chamber or lower chamber of the oil cylinder through each one-way valve and overflow valve. Under the action of high-pressure oil, the oil cylinder moves.

The press drives the flywheel by motor, and drives the crank connecting rod Zhidao mechanism through the clutch and transmission gear to make the sliding block move up and down, and drives the drawing die to form the steel plate.

Application:

The hydraulic press is suitable for bending, forming, flanging and other processes of center loaded 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. Stamping machine is mainly used for sheet metal parts processing.

classification

Classification of hydraulic press

Hydraulic press can be divided into hot forging hydraulic press, four column hydraulic press, single arm hydraulic press, gantry hydraulic press and double column hydraulic press

Press classification:

According to the slider driving force, it is divided into mechanical punch and hydraulic punch

According to the motion mode of the slider, it can be divided into single action, multiple action and multiple action

According to the slider driving structure, it can be divided into crankshaft type punch, non crankshaft punch, elbow joint punch, friction punch, screw punch, tooth answer bar punch, connecting rod punch and cam punch
