Embodiment 1

[0021] Such as figure 1 and figure 2 As shown, a roll surfacing machine includes a welding mechanism 15, a frame 14, a roller frame 7 and a welding torch moving mechanism. The welding mechanism 15 is installed on the frame 14, and the roller frame 7 is placed under the frame 14. There are two welding mechanisms 15 and roller frames 7, which are symmetrical along the longitudinal centerline of the frame 14.

[0022] The welding mechanism 14 includes a welding head 12 , a flux funnel 10 , a wire reel 9 and a control box 13 , and the flux funnel 10 is connected to the welding head 12 through a delivery pipe 11 .

[0023] The welding torch moving mechanism includes a welding torch lifting mechanism 4, a welding torch traveling mechanism 5, a cable towline 6 and a walking platform 3. The walking platform 3 is arranged on the surface of the frame 14, and the walking platform 3 is connected to the welding lifting mechanism 4 through the cable towline 6. The frame 14 is composed of...

Abstract

The invention belongs to the field of welding, and particularly relates to a special roll surfacing welding machine which comprises two welding mechanisms, a frame, two roller carriers and a welding gun moving mechanism. The welding mechanisms are mounted on the frame, the roller carriers are placed below the frame, and the welding mechanisms and the roller carriers are symmetric about the longitudinal center line of the frame. Each welding mechanism comprises a welding head, a flux hopper, a wire reel and a control box, wherein the flux hopper is connected with the welding head through a conveying pipe. The welding gun moving mechanism comprises a welding gun lifting mechanism, a welding gun travelling mechanism, a wiring drag chain and a travelling platform, wherein the travelling platform is arranged on the surface of the frame and connected with the welding gun lifting mechanism through the wiring drag chain. The special roll surfacing welding machine is simple in structure, low in cost and high in machining precision, and the rotating speed of a roll is uniform by the aid of the roller carriers.

Description

technical field [0001] The invention belongs to the field of welding, in particular to a special machine for surfacing welding of rolls. Background technique [0002] The roll is a tool for plastically deforming (rolled material) metal, and is an important consumable part that determines the efficiency of the rolling mill and the quality of the rolled material. The roll is an important part of the rolling mill in the rolling mill. It uses the pressure generated by a pair or a group of rolls to roll and roll the steel. It is mainly subjected to dynamic and static loads, wear and temperature changes during rolling. [0003] Surfacing welding, as an economical and rapid process method for surface modification of materials, is more and more widely used in the manufacture and repair of parts in various industrial sectors. In order to play the role of the surfacing layer most effectively, it is hoped that the surfacing welding method adopted has a small dilution of the base meta...
