Backward deformation welding process method for side beam of bogie

Номер: CN0102009278A
Автор: Peng Zhangwei
Принадлежит:

The invention discloses a backward deformation welding process method for the side beam of a bogie, which is characterized by comprising the following steps: firstly, carrying out track welding on an air spring seat board on the upper cover board of the side beam to form rigid fixing; and then welding the side beam. In the invention, the air spring seat board pairing process is performed before a side beam pairing process from a framework pairing process, the characteristic that the air spring seat board is similar to the upper cover board of the side beam in shape is utilized, and before the side beam is welded by a manipulator, the air spring seat board is subject to track welding on the upper cover board of the side beam to form rigid fixing, thereby effectively controlling welding deformation, improving product quality, improving production efficiency and reducing labor intensity.

The invention discloses a method for correcting and adjusting a rail by using pincer-like track jacks. The pincer-like track jacks comprise a pair of pincer-like members and a pair of jacks. The method is characterized by comprising the following steps: rotating the pair of pincer-like members formed by a left splint (1) and a right splint (2), and clamping the waist part of an I-steel rail (5) by using a hook end A' and a hook end B' of the pincer-like members; arranging the pair of jacks (4) on two sides of the I-steel rail (5) to ensure that the upper ends of the jacks (4) are respectively supported on a straight end A of the left splint (1) and a straight end B of the right splint (2) and the lower ends of the jacks (4) are respectively supported on a rail foundation (6) of the I-steel rail (5); and starting the jacks (4) to lift the straight ends A and B of the pincer-like members to jack and raise the rail (5) for correcting and adjusting the rail. The pincer-like track jacks for ...
