Problems solved by technology

Since the straight seam of the cylinder body, the circular seam of the cylinder head and the circular seam of the bottom seal of the existing cylindrical body prefabricated parts are all separate tooling, and each tooling needs to be manually repositioned and then welded, the operation is cumbersome and prone to failure. Positioning deviation seriously affects the processing quality, and the inspection procedure of post-weld quality is complicated, labor-intensive, high-cost, and easily leads to a large number of defective products, which is not conducive to the development of enterprises

Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings, according to Figure 1 to Figure 5 As shown, in the automatic welding method for heat exchangers of the present invention, the heat exchanger includes a heat exchange preform 1, and the heat exchange preform 1 has a cylindrical straight seam 3, a cylindrical head circumferential seam 4, and a cylindrical bottom cover. Circumferential seam 5, the automatic welding method includes the following steps:

[0032] 1) Prepare limit line 2; prepare limit line 2 on both sides of the cylinder straight seam 3 of the heat exchange preform 1, on both sides of the cylinder head circumferential seam 4, and on both sides of the cylinder bottom cover circumferential seam 5 respectively .

[0033] 2) The heat exchange preform 1 is positioned on the tooling; the heat exchange preform 1 is installed on the tooling equipment, and the straight seam 3 of the cylinder body is docked with the p...

Abstract

The invention provides an automatic welding method used for a heat exchanger and a device for the automatic welding method. The device comprises a rack and at least one set of automatic tool device adaptively assembled on the rack. Each automatic tool device comprises an installation seat, a lifting part, a pushing part, a clamping part, a rotating part, a mechanical hand welding gun and a gas protection part. By means of the automatic tool devices, cylinder body longitudinal joints, cylinder body head sealing circular joints and cylinder body bottom sealing circular joints of heat exchange prefabricated parts can be automatically and continuously completed simply by positioning and installing tools at a time, positioning is fast and accurate, high efficiency is achieved, and the welding effect is good; and due to the cooperation of a limiting line, whether the heat exchange prefabricated parts are qualified or not after welding can be conveniently checked, judging is convenient and fast, and the machining quality is ensured.

Description

technical field [0001] The invention relates to the field of heat exchanger manufacturing, in particular to an automatic welding method and equipment for heat exchangers. Background technique [0002] Most of the structure of the heat exchanger of the heat pump water heater includes a cylindrical body and a heat exchange tube, and the heat exchange tube is adapted and installed inside the cylindrical body. Wherein, the welding seam mode of the cylindrical body of the heat exchanger includes butt welding seam, and the butt welding seam includes a cylindrical body straight seam, a cylindrical body head circumferential seam, and a cylindrical body bottom circumferential seam of the cylindrical body prefabricated part. Because the cylindrical body straight seam, the cylindrical body head circumferential seam, and the cylindrical body bottom circumferential seam of the existing cylindrical body prefabricated parts are all separate tooling, and each tooling needs to be manually re...
