  • 如何选择液压扳手?

因为目前全球商业的广泛化,寻找到高强度材料的难度并非很大,然而因为为了进一部的进步强度,还必需采取热处理及表面处理,对于但愿部件强度达到1000MPa以上并且不乱,并且对于材质强度的平均性也要求极高,目前海内企业还很难对于液压方驱扳手内部零件的强度达到1000MPa以上,即使能个别达到,也很难达到批量的不乱性。还需要多向国外同类产品学习,在一个较长的时期内,投入较多的人力与资金,在材质与热处理的方面多加以试探和实验。下面小编就带您了解下液压扳手吧!

Because of the current global commerce, it is not very difficult to find high-strength materials. However, in order to improve the strength of a part, heat treatment and surface treatment are also necessary. It is also very important to hope that the strength of the parts will reach more than 1000MPa without disorder, and the average strength of the materials is also very high. At present, in China, heat treatment and surface treatment are required. It is difficult for enterprises to achieve the strength of the internal parts of hydraulic square-drive wrench more than 1000MPa, even if it can be achieved individually, it is also difficult to achieve the non-chaotic batch. We also need to learn more from similar products abroad, invest more manpower and capital in a long period of time, and try and experiment in material and heat treatment. The following small knitting will take you to understand the hydraulic wrench bar!

一般有几种规格,例如M36、M42、M48,如果不说螺母多大,是按公制螺栓螺母副配套筒的对边,M36在的螺母六角对边是55,M42是65,M48是75。如螺栓规格跨度太大,而且扭矩跨度较大,那预紧这些螺栓就必然要选用两种型号扳手。螺栓的规格、螺栓的强度等级是液压扭矩扳手选型的最关键参数,螺栓不同,扭矩不同,同样的螺栓强度等级不同扭矩不同,同样螺栓强度等级,不同工况的扭矩也不同,用于轧机设备和化工设备上螺栓扭矩是不一样的,一般的设计图纸都会给出扭矩大小。

Generally, there are several specifications, such as M36, M42, M48. If you don't say how big the nut is, it's the opposite side of the matching barrel of the metric bolt nut pair. M36 is 55 on the hexagonal opposite side of the nut, M42 is 65, M48 is 75. If the span of bolt specification is too large and the span of torque is too large, two types of wrenches must be selected to pre-tighten these bolts. The specifications of bolts and the strength grade of bolts are the most critical parameters for the selection of hydraulic torque wrenches. Different bolts and different torques make different bolt strength grades and different torques. The same bolt strength grades and different working conditions have different torques. The bolt torques used in rolling mills and chemical equipment are different, general. The design drawings give the magnitude of the torque.
