Device for controlling welding stress deformation along with soldering impact, revolving and extrusion pressing

Abstract

A weld with trailing rotation extruding to control residual stresses deformation device relates to a device for controlling the residual stress deformation of a thin-walled metal. The weld with trailing impact rolling to control residual stresses deformation device has the disadvantages that the device has a loud noise during operation and a bad working environment and that the device is easily influenced by the impact rolling wheel and the size of the welding torch and that the distance between the wheel and the torch can not satisfy the theoretical ideal value. The upper end of a compression rod (2) is inserted into the part of the head of an electric hammer (14), which is fastened on a No.2 support (15). A pair of sliders (6) which mate with two guide rails (7) and a nut (8) which mates with an elevating screw (10) are fixed on the other side of the bottom plate (12). Both ends of the guide rail (7) are fixedly arranged on a support (5). The two guide rails (7) are parallel with the elevating screw (10), both ends of which are equipped with bearings (13). The support (5) is fixed on a base (12). The present invention with an adjustable frequency impact force can effectively prevent a welding hot cracking as well as control a straight weld and an enclosed circumferential weld.

Description

technical field [0001] The invention relates to a device for controlling welding stress deformation of thin-walled metals. Background technique [0002] Welding of high-strength thin-walled materials, the stress deformation is large, and thermal cracks are prone to occur. Correction and heat treatment are required after welding, which increases production costs, affects product quality, and even produces waste products. In order to solve the above problems, a variety of methods such as rolling with welding, static and dynamic temperature difference stretching and hammering with welding have been proposed at home and abroad, and the devices for realizing these methods, but they generally have low production efficiency, high cost, and poor working environment. and other shortcomings. The rolling method with welding has disadvantages such as large size of the impact rolling wheel and easy occurrence of arcing due to interference with the welding torch, so it is difficult to be...
