Description

Technical Field

[0001] This invention relates to the field of environmental protection equipment, and in particular to a novel welding equipment for bag filter cover plates and its application method. Background Technology

[0002] The bag filter cover welding equipment is a supporting device for welding the upper cover plates of bag filter dust collectors. Hundreds of identical cover plates are evenly distributed in the upper chamber. Maintaining the temperature of the upper chamber is crucial to ensuring that the dimensions of the cover plates and the chamber openings correspond and match, ensuring that the assembly is within tolerance and installed smoothly. With the continuous development of technology, people have increasingly higher requirements for the manufacturing process of bag filter cover welding equipment.

[0003] Existing baghouse dust collector cover welding equipment has certain drawbacks. The upper chamber contains hundreds of identical cover plates. Maintaining the temperature of the upper chamber hinges on ensuring the cover plates and their dimensions align correctly, guaranteeing successful installation within tolerances. Currently, cover plate splicing and welding is primarily done manually on a welding platform, resulting in simple, free-form welding that fails to guarantee dimensional uniformity and interchangeability. This leads to extremely low welding efficiency, making on-site installation difficult and requiring frequent adjustments, with many covers needing to be returned to the manufacturer for repair. To address these shortcomings... A novel baghouse dust collector cover welding equipment was designed. In the splicing process, the tooling bending plate positioning and adjusting bolts were finely adjusted to strictly control the uniformity and interchangeability of the cover's external dimensions, achieving standardized cover dimensions. In the welding process, the cover welding equipment was positioned using two welding production lines. After welding, the welding robot rotated 180 degrees to continue welding on the other line, improving the appearance and welding quality, increasing the accuracy of the assembly dimensions with the hopper opening, and improving welding efficiency, ensuring smooth on-site installation. Therefore, we propose a novel baghouse dust collector cover welding equipment and its usage method. Summary of the Invention
