A welding device for plate-type heat exchanger headers

Abstract

The present invention is applicable to the technical field of welding headers of plate-type heat exchanger modules, and in particular relates to a welding assembly device for headers of plate-type heat exchanger modules, comprising a working base, a mounting seat connected to both sides of the surface of the working base, and a first hydraulic push rod installed on the side of the mounting seat, one end of the first hydraulic push rod being connected to a support vertical plate. The present invention can effectively solve the problem of uneven pressure during the assembly process of header workpieces by providing an upper arc-shaped clamping plate, a first mounting bracket, a pressurized movable rod, a sealing sleeve, a connecting column, a groove, a limiting protrusion, a hydraulic pump, an oil pipeline, a second mounting bracket, a second pressure sensor and a pressure measuring rod. By measuring and adjusting the pressure in real time, the pressure on the upper and lower arc-shaped clamping plates is uniform, thereby ensuring that the pressure on the end faces of the two header workpieces is consistent. This pressure uniformity significantly improves the welding quality, reduces welding defects such as pores and inclusions, and thereby improves the strength and reliability of the welded joint.
