Problems solved by technology

At present, the method of manual hand welding is used in China to surfacing stainless steel on its outer circular surface. The efficiency is low, and the surfacing layer is prone to defects, and the product quality is unstable. Production efficiency and surfacing quality, but because the workpiece weighs 80 tons, the special welding positioner has a very large structure and high cost, which directly restricts the application of automatic welding technology

Abstract

The invention relates to an automatic surfacing welding device and method of a runner hub, wherein one end of the runner hub is clamped on a front lathe chuck and the other end of the runner hub is arranged on a support roller rack. The rotation axis of a swinging device is set at the same height as a horizontal axis of the runner hub. An automatic submerged arc electric welding head is arranged on the end part of the swinging device. A swinging axis center of the automatic submerged arc electric welding head coincides with a surfacing welding spherical surface center of the runner hub. The welding steps are as follows: 1) clamping the runner hub so that the axis of the runner hub and the rotation axis of a lathe are coaxial; 2) swinging the automatic submerged arc electric welding head on the generatrix on which the vertex of the surfacing welding spherical surface is located; and 3) welding under the protection of CO2, wherein the rotation linear velocity of a principal axis is 150-300mm / minute, and the swing linear velocity is 10-20mm / hour. The device provided by the invention has the following beneficial effects: the automatic surfacing welding of a large revolution body with a spherical surface can be achieved by using related functions of conventional equipment, and the structure of the device is simple and effective with wide scope of application.

Description

technical field [0001] The invention relates to the field of surfacing welding of large-scale rotary bodies, in particular to an automatic surfacing welding device and method for a rotary body. Background technique [0002] The structure of the runner body is shown in image 3 , it is the key component of the runner in the water turbine, and its manufacturing quality directly affects the working state of the water turbine. Most of its outer circular surface is a spherical structure. In order to ensure the wear resistance and Corrosive, the surface is surfacing with stainless steel with a thickness of 4-8mm. At present, the method of manual hand welding is used in China to surfacing stainless steel on its outer circular surface. The efficiency is low, and the surfacing layer is prone to defects, and the product quality is unstable. Production efficiency and surfacing quality, but because the workpiece weighs 80 tons, the special welding positioner has a very large structure ...
