  众所周知,挖掘机的紧张布局部分是延伸臂,通常是焊接的。 当焊接延伸臂时,会发生一定的外形改造,即焊接变形,这告急影响了以后运用该构件的结果。 长臂焊接变形的紧张情势和缘故缘故原因是什么? 今天,挖掘机加长臂制造商将带您学习以下相关内容!
  It is well known that the main structural part of excavators is the extension arm, which is usually welded. When the elongation arm is welded, a certain shape change will occur, that is, welding deformation, which seriously affects the effect of using the component in the future. What are the main forms and causes of long arm welding deformation? Today, excavator arm manufacturers will take you to learn the following related content!
  敷衍长臂焊接,钢板的厚度通常在4至100毫米之间,并且钢板的厚度十分大。 在相应范围内运用的焊接工艺参数改造很大,招致出入焊接温度场的焊接热量不匀称。 因此,要是在焊接进程中控制不当,焊接变形将十分大,告急影响挖掘机延伸臂的加工质量和零件的装置。 变形的基本模范是横向,纵向紧缩,角度变形,弯曲和波浪变形。
  For long arm welding, the thickness of steel plate is usually between 4 and 100 mm, and the thickness of steel plate is very large. The welding parameters used in the corresponding range vary greatly, resulting in uneven welding heat in and out of the welding temperature field. Therefore, if the welding process is not properly controlled, the welding deformation will be very large, seriously affecting the processing quality of the excavator extension arm and the assembly of the whole machine. The basic types of deformation are transverse, longitudinal contraction, angular deformation, bending and wave deformation.
  控制挖掘机伸缩臂变形的技术要领:
  Technical methods for controlling the deformation of telescopic arm of excavator:
  (1)采取焊接变形控制技术
  (1) Welding Deformation Control Technology
  公允选择焊接要领和焊接工艺参数,应围绕布局的中性轴以平衡的要领陈设焊缝,应公允选择焊接序次,应采取反向和中缀焊接,抗变形量应 预设,并且可以壮实刚度。 呆板校正和火焰校正要领通常用于已发生的变形。 这些变形防范步谐和校正进程紧张寄予阅历和有限的测试数据,并且不克不及顺应庞大和可变的布局模范和焊接要领,并且焊接变形十分昂贵。 时间,精神,致使招致江苏快三开奖结果产品报废。

  The welding method and welding process parameters shall be selected reasonably. The weld shall be arranged in a balanced way around the neutral axis of the structure. The welding sequence shall be selected reasonably. The reverse and intermittent welding shall be adopted. The deformation resistance shall be preset and the rigidity can be fixed. Mechanical correction and flame correction methods are usually used for deformations that have occurred. These deformation prevention measures and correction process mainly rely on experience and limited test data, and can not adapt to complex and variable structural types and welding methods, and welding deformation is very expensive. Time, energy, and even lead to product scrap.
  (2)焊接变形预测要领的运用
  (2) Application of Welding Deformation Prediction Method
  焊接数值模拟可用于模拟庞大或不可观察的焊接征象,并预测在十分环境下未知的端正,以阐发焊接进程的端正。 作为一种贫弱的定量研讨要领,数值模拟不但可以资助明白焊接征象的性子,预测渣滓应力和变形,并且可以用作研讨控制和淘汰渣滓应力并优化焊接质量的东西。
  Welding numerical simulation can be used to simulate complex or unobservable welding phenomena and predict unknown rules in extreme cases to clarify the rules of welding process. As a powerful quantitative research method, numerical simulation can not only help to understand the nature of welding phenomena, predict residual stress and deformation, but also be used as a tool to control and reduce residual stress and optimize welding quality.
