Description

Technical Field

[0001] The utility model relates to the technical field of wire feeding devices for end-cap welding, in particular to an automatic wire feeding mechanism for end-cap welding. Background Art

[0002] The head is an important component of pressure vessels such as boilers, oil refining equipment and chemical equipment. The head can be divided into flat-bottomed heads, dished heads, elliptical heads and spherical heads according to its shape. The head is a typical workpiece for thick plate forming. Thick plate forming generally refers to the stamping of large parts with a thickness of more than 6mm. The workpiece material can be carbon steel, alloy steel, stainless steel and non-ferrous metal. In the process of welding the head, it is necessary to continuously feed the welding wire to the weld of the head and weld synchronously through the welding gun. The process of feeding the welding wire is called wire feeding, so an automatic wire feeding device is required.

[0003] After searching, the patent publication number CN216990303U discloses a plasma gun holder wire feeding mechanism for head processing, including a feeding drum, a movable frame and a welding gun, and also including a flattening wire feeding device. The flattening wire feeding device is arranged at the side end of the feeding drum, the movable frame is arranged on the flattening wire feeding device, and the welding gun is arranged on the movable frame. The flattening wire feeding device includes a first wire feeding assembly, a second wire feeding assembly, a driving motor and a limit mounting plate. There are two limit mounting plates, and the two limit mounting plates are symmetrically arranged at the side ends of the feeding drum. The first wire feeding assembly and the second wire feeding assembly are symmetrically arranged from top to bottom between the two limit mounting plates. There are two driving motors, and a driving motor is provided on each of the first wire feeding assembly and the second wire feeding assembly. This device achieves the effect of ensuring that the welding wire is in a flat state and the conveying direction will not be offset during the welding wire conveying process.

[0004] There are still some disadvantages in the above patent. Although the welding wire can be cleaned by a cleaning brush, the cleaning brush is located inside the limiting cylinder. After long-term use, there is a lot of dust inside the cleaning brush, which makes it inconvenient to clean or replace the brush inside the limiting cylinder, thus affecting the cleaning effect of the welding wire. Utility Model Content
