You must be familiar with the mechanical equipment of the excavator. Maybe you rarely touch it in your daily life, but you have to better understand its basic performance. But how much do you know about the excavator's long arm? How does it work.

　　挖掘机的伸缩臂可分为两段、三段和四段。两段主要适用于土质、砂土、混凝土的施工输送、公路边坡的修整、河道的疏浚、疏浚、施工基础、河道、深沟等土方开挖。因为第，二部分的扩展业务的成本比较高,为了节约成本,部门产品出现在市场上,也就是说,在更初的前臂的挖掘机手臂部分设置在马的原始前臂挖掘机琯头山,另一端的桶(普通斗容量不超过1/3的原始桶)操作。

　　The telescopic arm of excavator can be divided into two sections, three sections and four sections. The two sections are mainly applicable to the construction and transportation of soil, sand and concrete, the trimming of highway slope, the dredging and dredging of river channel, the excavation of construction foundation, river channel, deep ditch and other earthwork. Because the cost of expanding business in the second part is relatively high, in order to save costs, department products appear in the market, that is to say, the arm of the excavator in the initial forearm is set in guantoushan, the original forearm excavator of the horse, and the bucket at the other end (the ordinary bucket capacity is not more than 1 / 3 of the original bucket) is operated.

　　因为挖掘机延长臂是大型重工业产品,因此需要一个大型专用设备的加工和生产效率高、质量高,保证加工质量和制造水平,在的程度上,如:数控等离子切割机、大型斜铣边机,研磨机,大排量的焊接机,大型镗床、着陆大丸清理机(必要),等等。

　　Because the extension arm of excavator is a large-scale heavy industrial product, it needs a large-scale special equipment with high processing and production efficiency and quality to ensure the processing quality and manufacturing level, to the greatest extent, such as: CNC plasma cutting machine, large oblique milling machine, grinder, large displacement welding machine, large boring machine, landing large shot cleaning machine (necessary), etc.

　　挖掘机的伸缩臂是如何分类和加工的?

　　How to classify and process the telescopic arm of excavator?

　　挖掘机伸缩臂的生产:

　　Production of excavator telescopic boom:

　　一般采用三维计算机辅助设计系统进行应力分析和仿真。此外，加工设备、员工的熟练程度、实际应用知识、经验、选材、生产工艺等方面都对挖掘机伸缩臂的结构强度、性能和质量有重要影响。

　　Generally, three-dimensional CAD system is used for stress analysis and simulation. In addition, the processing equipment, employee's proficiency, practical application knowledge, experience, material selection, production technology and other aspects have an important impact on the structural strength, performance and quality of the excavator's telescopic arm.

　　一般过程和过程:电脑设计,数控切割(mn) -折弯机折弯形状(马)——技术人员焊接、大型镗床无聊,延长臂base -挖掘机铲斗油缸和管道安装、压力测试,产品抛丸- - - - - - - - - - -热喷涂,详细的交货前检验,合格的工厂。

　　General process and process: computer design, NC cutting (MN) - bending shape of bending machine (horse) - Welding of professional technicians, boring of large boring machine, installation of bucket cylinder and pipe of extension arm base excavator, pressure test, shot blasting treatment of products ------ thermal spraying, detailed pre delivery inspection, qualified factory.

　　事实上，对于挖掘机来说，基本上所有的变化都来自于挖掘机电机臂长度的变化。动臂一直是挖掘机的重要组成部分，在工作中具有较大的结构尺寸和较大的冲击力，因此对加工质量要求较高。在以上内容中，我们详细介绍了挖掘机伸缩臂的加工改造知识。希望对您有所帮助。如果您有任何其他问题，请随时咨询我们。

　　In fact, for excavators, almost all the changes come from the change of the length of the excavator motor arm. Boom is always an important part of excavator. It has a large size and impact force in the work, so it has a high requirement for processing quality. In the above content, we introduced the knowledge of machining and transformation of the telescopic arm of excavator in detail. I hope it will help you.
