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.
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.
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.
How are the telescopic arms of excavators classified and processed?
Production of excavator telescopic boom:
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.
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.
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.
