A dual-purpose device for welding and cutting

Abstract

The invention discloses a novel welding and cutting dual-use device. The novel welding and cutting dual-use device comprises an upper clamp ring and a plasma welding-cutting machine. A lower clamp ring is arranged under the upper clamp ring, and a welding-cutting gun fixing support is arranged in the upper clamp ring. Power wire slots and six conductive devices are arranged in the upper clamp ring and the lower clamp ring, and springs and balls are arranged in the conductive devices. Extension feet I are arranged on the left side and the right side of the upper clamp ring, and round holes are formed in the extension feet I. Extension feet II are arranged on the left side and the right side of the lower clamp ring, and nuts are welded to the bottoms of the extension feet II. The nuts and the round holes are in central symmetry. The extension feet I are connected with the extension feet II through bolts, and a welding-cutting device is arranged on the right sides of the upper clamp ring and the lower clamp ring. The upper clamp ring and the lower clamp ring are arranged and matched with the welding-cutting gun fixing support, so that weld line deviation is small in the welding process; additionally, the balls in the conductive devices can roll on the surface of a workpiece, so that burns, caused by poor ground in the welding process, on the surface of the workpiece can be reduced, and therefore the novel welding and cutting dual-use device has high practicality.

Description

technical field [0001] The invention relates to welding and cutting, in particular to a dual-purpose device for welding and cutting. Background technique [0002] When welding and cutting round pipes at the construction site, there is no good cutting device, resulting in uneven cuts or inclined cuts. When the pipes are connected, the pipes are not horizontal or the gap between the joints is large or small. Welding It causes a lot of inconvenience, and even affects the quality of the weld seam. At the same time, due to the limitation of the station during on-site welding, many welding positions are not easy to be welded, and the quality of the weld seam is difficult to guarantee, especially when welding pressure pipes. Some professional welding and cutting equipment have complex structures, high prices, large volume, inconvenient transportation, and cannot carry out welding and cutting operations on site. Large, only its transportation cost is a problem, so a welding and cut...

[0002] When welding and cutting round pipes at the construction site, there is no good cutting device, resulting in uneven cuts or inclined cuts. When the pipes are connected, the pipes are not horizontal or the gap between the joints is large or small. Welding It causes a lot of inconvenience and even affects the quality of the weld seam. At the same time, due to the limitation of the station during on-site welding, many welding positions are not easy to be welded, and the quality of the weld seam is difficult to guarantee, especially when welding pressure pipes. Some professional welding and cutting equipment have complex structures, high prices, large volume, inconvenient transportation, and cannot carry out welding and cutting operations on the spot. Large, only its transportation cost is a problem, so a welding and cutting device with simple structure, reliability and portability needs to be developed
