英国最近制造出一种罗兹(Rhodes)弯刀剪切机,它与传统的剪切机不同,机中上剪刀不用斜刀而改用弯刀。剪切机里采用一套液压传动系统和灵巧的板料操纵机构,可以自动来回地切割板料。弯刀转动剪切板料,没有交搭现象,因而剪料的弯曲与歪斜变形可减至最小。弯刀来回转动自动切割板料可以节省加工时间,同时剪板时发出的噪声也较小。这种剪切机有三种不同的加工速度,适用剪切板料厚度为6～25mm。弯刀剪切机的工艺原理见附图: (1)剪切机准备开动,此时向前移动板料至定位装置处。开动机器时,液压动力活塞就带动横杠L沿
The UK recently created a Rhodes machete shear that differs from traditional shears in that it uses a machete instead of a bevel knife. The shear incorporates a hydraulic drive system and a smart sheet handling mechanism that automatically cuts the sheet back and forth. Scimitar rotating shear sheet, there is no cross-docking phenomenon, and thus cut the material bending and skew deformation can be minimized. Turning the machete back and forth to automatically cut the sheet can save processing time and at the same time generate less noise when shearing. This shear has three different processing speeds, suitable for cutting sheet thickness of 6 ~ 25mm. The machete shear machine process principle see attached map: (1) shear machine is ready to start, this time moving the sheet forward to the positioning device. When the machine is started, the hydraulic power piston drives the L bar of the bar
