You must be familiar with the mechanical equipment of the excavator. Maybe you rarely touch it in your daily life, but you must better understand its basic performance. But how much do you know about the lengthening arm of excavator? How does it work? The following small series will introduce you in detail.

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 boom 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, river dredging, dredging, construction foundation, river channel, deep ditch and other earthwork excavation. Because the cost of expanding the business of the second part is relatively high, in order to save costs, departmental products appear in the market, that is, the excavator arm of the earlier forearm is set in guantoushan, the original forearm excavator of Ma, and the bucket at the other end (the capacity of the ordinary bucket does not exceed 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 excavator extension arm is a large-scale heavy industrial product, it needs a large-scale special equipment with high processing and production efficiency and high quality to ensure the processing quality and manufacturing level, to a certain extent, such as NC plasma cutting machine, large oblique edge milling machine, grinder, large discharge 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 are the telescopic arms of excavators classified and processed?

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 computer-aided design system is used for stress analysis and simulation. In addition, the processing equipment, the proficiency of employees, practical application knowledge, experience, material selection and production technology all have an important impact on the structural strength, performance and quality of excavator telescopic boom.

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 machine bending shape (horse) - technicians' welding, boring of large boring machine, extension arm base - excavator bucket oil cylinder and pipeline installation, pressure test, product shot blasting treatment ----------- 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, basically all changes come from the change of excavator motor arm length. Boom has always been an important part of excavator. It has large structural size and large impact force in work, so it has high requirements for processing quality. In the above content, we introduced the processing and transformation knowledge of excavator telescopic arm in detail. Hope to help you.
