青岛切割机械厂生产的多向半自动气割机,为大合拢接缝的全位置机械化切割提供了实现的可能。我们根据生产需要,对其进行了下述改装。(1)为使两条割缝互相平行,在横向滑杆上装置两把割炬,依靠两割炬行走轨迹的等距性来达到割缝的互相平行。并且两割炬的相对位置可以移动,以便调节割缝距离(图1)。(2)为了便于调节切割火焰和去除切割氧孔内的飞溅金属,在横向滑杆上增添了一个摇倒装置。它能将割嘴方便地旋转90°角。
Qingdao Cutting Machinery Factory production of multi-directional semi-automatic gas cutting machine, fully closed seam for the full mechanized cutting provides the possibility of realization. According to the production needs, we have the following modifications. (1) In order to make two kerfs parallel to each other, two cutting torches are mounted on the horizontal slide bar, and the kerfs are parallel to each other by means of the equidistance between the two torch walking tracks. And the relative position of the two torches can be moved in order to adjust the kerf distance (Figure 1). (2) In order to facilitate the adjustment of the cutting flame and the removal of the spattered metal in the cutting oxygen hole, a deflection device is added to the lateral slide bar. It can easily rotate the cutting tip by 90 °.
