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.

挖掘機的伸縮臂可分為兩段、三段和四段。兩段主要適用于土質、砂土、混凝土的施工輸送、公路邊坡的修整、河道的疏浚、疏浚、施工基礎、河道、深溝等土方開挖。因為二部分的擴展業務的成本比較高,為了節約成本,部門產品出現在市場上,也就是說,在更初的前臂的挖掘機手臂部分設置在馬的原始前臂挖掘機琯頭山,另一端的桶(普通斗容量不超過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.

因為挖掘機延長臂是大型重工業產品,因此需要一個大型專用設備的加工和生產效率高、質量高,保證加工質量和制造水平,在的程度上,如:數控等離子切割機、大型斜銑邊機,研磨機,大排量的焊 接機,大型鏜床、著陸大丸清理機(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.

挖掘機的伸縮臂是如何分類和加工的?

How are the telescopic arms of excavators classified and processed?

挖掘機伸縮臂的生產:

Production of excavator telescopic boom:

一般采用三維計算機輔助設計系統進行應力分析和仿真。此外，加工設備、員工的熟練程度、實際應用知識、經驗、選材、生產工藝等方面都對挖掘機伸縮臂的結構強度、性能和質量有重要影響。

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.

一般過程和過程:電腦設計,數控切割(mn)-折彎機折彎形狀(馬)——技術人員焊 接、大型鏜床無聊,延長臂base-挖掘機鏟斗油缸和管道安裝、壓力測試,產品拋丸-----------熱噴涂,詳細的交貨前檢驗,合格的工廠。

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.

事實上，對于挖掘機來說，基本上所有的變化都來自于挖掘機電機臂長度的變化。動臂一直是挖掘機的重要組成部分，在工作中具有較大的結構尺寸和較大的沖擊力，因此對加工質量要求較高。在以上內容中，我們詳細介紹了挖掘機伸縮臂的加工改造知識。希望對您有所幫助。如果您有任何其他問題，請隨時咨詢我們。

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.
