Description

An anti-deformation assembly line

technical field

The invention relates to the technical field of steel structure processing, in particular to an anti-deformation assembly line.

Background technique

In the manufacturing process of large steel structures, the welding of large steel bridge decks and U ribs has always been the focus of steel bridge production.

Due to the corresponding deformation force will be generated when the steel bridge deck and U-shaped rib corners are spot welded, and the thermal stress will cause the structure to shrink and deform. After the steel bridge deck is clamped by the clamp on the tire frame, before the steel bridge deck and the U-rib are internally welded, it is necessary to slide along the base to the steel bridge deck and the U-rib through the prestressing device on the assembly base carrying the tire frame. The welded position of the U-rib applies stress opposite to the welding deformation to the steel bridge deck to restore the deformed steel bridge deck, and when the stress applying device applies stress to the steel bridge deck, the reaction force hook on the steel bridge deck will hook Hold the bottom of the base and apply a reverse pull to the stressing device to prevent the prestressing device from separating from the assembly base.

However, the contact area between the current reaction force hook and the hooked part of the assembly base is small. When the reaction force hook is set on the bottom of the assembly base, a large pressure is generated on the bottom of the assembly base, so that the base hook is located at the bottom of the assembly base. Dent or even puncture, causing damage to the base.
