加长臂挖掘机弹性臂开裂该怎么处理?

日期:2019-01-04   来源:
最近有许多做挖掘机行业的朋友打电话资讯我们说自己的长臂挖掘机弹性臂开裂,今天小编特此整理了一篇文章来供我们参阅。
Recently, many friends in the excavator industry called us to tell us that the elastic arm of their long arm excavator was cracked. Today, Xiao Editor has arranged an article for us to refer to.
挖掘机弹性臂焊接前有必要清理,也就是把本来的开裂焊肉拿掉,用交相磨光机磨或有条件就用碳弧气刨,但刨后有必要打磨干净氧化铁。
It is necessary to clean up the elastic arm of excavator before welding, that is to say, to remove the original cracked welded meat, to grind it with a cross-polishing machine or to use carbon arc air gouging when conditions permit, but it is necessary to clean iron oxide after planed.
有可能的话还需要在焊接方位预热100度,然后再用直径3.2J507焊条焊,焊一会就停下来,用锤子敲击焊缝和焊缝边际,待完全焊完后一向用锤子敲击,直到焊缝根本冷却。
If possible, it also needs to preheat 100 degrees in the welding orientation, and then weld with 3.2J507 electrode of diameter. The welding will stop after a short time. The welding seam and the edge of the weld will be hit with a hammer. After complete welding, hammer will be used to knock until the weld is completely cooled.
目的是释放焊接应力,由于焊后不行能做热处理。焊接时有必要确保焊透,如果焊缝方位空隙大可以在里面加背板。
The purpose is to release the welding stress, because heat treatment can not be done after welding. It is necessary to ensure penetration during welding. If the weld seam has a large azimuth gap, the back plate can be added inside.
总的来说,由于每个挖机开裂的状况都不相同,我们举一个下面的比如,根本可以说明大部分状况。
Generally speaking, because each excavator cracks differently, let's take the following example to illustrate most of the situation.
进程一,由挖掘机弹性臂开裂处左右各割去侧板180mm至200mm,下面的盖板以侧板割去的宽度基础上再多割去约150mm。图中蓝色部分为侧板割去部分,赤色为下盖板割去部分。

In process one, the side boards are cut from the left and right sides of the elastic arm crack of excavator from 180 mm to 200 mm, and the lower cover is cut from the width of the side boards to about 150 mm more. In the picture, the blue part is the cut part of the side plate, and the red part is the cut part of the lower cover plate.
进程二,在开裂的盖板下面打好衬板,焊好,盖板裂缝也同时焊好。焊接进程应该平整无气泡产生。
In process two, the lining plate is welded under the cracked cover plate, and the cracks in the cover plate are welded at the same time. The welding process should be smooth and free of bubbles.
进程三,焊好后,根据进程一中切去的蓝色部分侧板,按尺寸重新切割一块铁板焊接上去,且在里面打上衬板。衬板要比封上去的侧板长点。
In process 3, after welding, according to the blue side plate cut out in process 1, a piece of iron plate is re-cut and welded according to its size, and the lining plate is inserted inside. The liner is longer than the sealed side plate.
进程四,完结上步后,就差底盖板没有封上了,在封底盖板之前,还是先打衬板,打完衬板及封好底板后,挖掘机弹性臂修补工作根本完结,可以打磨,补腻子上油漆了。
Fourth, after the completion of the step, the bottom cover is not sealed. Before sealing the bottom cover, the lining board should be punched first. After finishing the lining board and sealing the bottom plate, the repairing work of the elastic arm of the excavator is basically finished. It can be polished and repaired with putty paint.
