Abstract

The embodiment of the invention provides a longitudinal seam welding device for a 5 M-class storage-box bottom. The longitudinal seam welding device solves the problems that positioning accuracy of an existing 5 M-class storage-box bottom is low and the tool rigidity of the 5 M-class storage-box bottom is weak. The longitudinal seam welding device for the 5 M-class storage-box bottom comprises a portal support (1), a longitudinal guild rail (2), a portal guild rail (3), a welding unit (4), a dislodgement machine (5) and a welding die tyre (6); the longitudinal guild rail (2) is fixed to the foundation, and the tail end of the portal support (1) slides longitudinally along the longitudinal guild rail (2); the top end of the portal support (1) is provided the portal guild rail (3), and the welding unit (4) slides along the portal guild rail (3); the dislodgement machine (5) is located under the portal support (1); the welding die tyre (6) is arranged on the dislodgement machine (5) and conducts horizontal rotating and vertical flip-flop movement along with the dislodgement machine (5).

Description

technical field

[0001] The invention relates to welding technology, in particular to a 5M level storage tank bottom longitudinal seam welding equipment. technical background

[0002] In the past few decades, the longitudinal seam welding of the tank bottom in my country has experienced the gradual development process of manual welding, semi-automatic welding and automatic welding. However, as the size of the rocket storage tank increases to 5M level, the wall thickness of the tank bottom is thin and the rigidity is weak, so there is a higher requirement for the quality of the tailor welding of the tank bottom. Due to the following problems, the existing welding equipment for the longitudinal seam of the bottom of the storage tank cannot meet the precision requirements for the welding of the longitudinal seam of the bottom of the 5M storage tank.

[0003] 1. Low positioning accuracy: The existing longitudinal seam welding equipment has relatively low positioning accuracy due...
