| titleOfInvention | The anti-deformation method of a kind of factory ship T profile |
| abstract | The anti-deformation method of a kind of factory ship T profile, belong to Marine engineering technical field, comprise the following steps: A first offers row's rectangular channel at moulding bed, and B adjusts the position of fountain head, plasma cut head, hydrojet nitrogen head, makes it on the same line, C adds man-hour when starting plasma cut, first make hydrojet nitrogen head spray liquid nitrogen to T profile, form pre-bending power after cooling, then cut, the high-temperature expansion produced just in time offsets pre-bending power, reaches dynamic equilibrium; D fountain head starts water spray and carries out reducing temperature twice, makes the temperature of T profile both sides substantially identical; The T profile at E fountain head rear is covered with copper coin, be placed with bobbing machine above, temperature and the internal stress of T profile both sides can be regulated like this, it is made finally to reach two balances of internal temperature and stress, T profile after F processes like this, be straight after moulding bed is taken off, correct without the need to secondary, working (machining) efficiency improves greatly. |
