冲压机和液压机的区别与不同特点

作者:admin    来源:未知    发布时间:2020-07-11 23:35    浏览量:

液压机:液压机是一种以液体为工作介质,利用液体来传递压力以实现各种工艺的机器。

冲压机:冲压机也叫冲床,主要用作钣金零件的加工。

 

二者的区别还是很多的,具体如下

原理上:

液压机是油泵把液压油输送到集成插装阀块,通过各个单向阀和溢流阀把液压油分配到油缸的上腔或者下腔,在高压油的作用下,使油缸进行运动。

冲压机是通过电动机驱动飞轮,并通过离合器,传动齿轮带动曲柄连杆zhidao机构使滑块上下运动,带动拉伸模具对钢板成型。

用途上:

液压机适合于中心回载荷零件的弯曲、成型、翻边等多种工艺,配上冲裁缓冲装置后,还可以用于冲孔,落料加工,是船舶行业、压力容器行业、化工等行业的首选产品。冲压机主要用作钣金零件的加工。

 

分类

液压机分类

液压机可分为热锻液压机,四柱液压机,单臂液压机,龙门式液压机,双柱液压机

冲压机分类:

按滑块驱动力分机械式冲床 ,液压式冲床

依滑块运动方式分单动,复动,多动

依滑块驱动结构分曲轴式冲床 ,无曲轴式冲床,肘节式冲床,摩擦式冲床,螺旋式冲床 ,齿答条式冲床,连杆式冲床,凸轮式冲床

 

 

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
