Example Embodiment

[0031] Example 1

[0032] One of the specific implementations of the heat exchanger diaphragm seal weld seam welding machine of the present application. The heat exchanger diaphragm seal weld seam welding machine is applied to the welding of the heat exchanger diaphragm seal weld seam 10. Refer to the prior art figure 1 with figure 2 As shown, the heat exchanger includes a tube bundle 2, a tube shell 3, and a tube box 4. The tube bundle 2 penetrates through the tube plate 5. The tube box 4 is provided with a spherical diaphragm sealing disk 6, and the spherical diaphragm sealing disk 6 is provided in the tube box. Between the end 9 and the end cap 7 of the pipe box; the spherical diaphragm sealing disc 6 includes a spherical diaphragm 61 arranged in the middle and a flat cushion ring 62 arranged along the outer circumferential side of the spherical diaphragm 61; a flat cushion ring 62 The tube box end 9 is sealed with a sealing weld 10; the tube box end 9 and the tube box end cov...

[0038] Example 2

[0039] The second specific implementation of the heat exchanger diaphragm seal welding machine of the present application. The main technical solution of this embodiment is the same as that of Embodiment 1. For the features not explained in this embodiment, the explanation in Embodiment 1 is adopted. I will not repeat them here. The difference between this embodiment and embodiment 1 is that reference image 3 As shown, the frame 12 is provided with an adjusting spoke 15 with a sliding groove in the middle, and the frame 12 is fixed to the end 9 of the tube box through the adjusting spoke 15. Generally speaking, the 9 manholes at the end of the pipe box are relatively fixed. 500mm to The change range of 700mm, adjusting the spokes 15 to expand and contract in the radial direction can be applied to the center circle of the threaded hole 91 of the tube box end 9 600mm to 800mm variation range, but the above variation range can be changed according to design n...

Example Embodiment

[0041] Example 3

[0042] The third specific implementation manner of the heat exchanger diaphragm seal welding machine of the present application. The main technical solution of this embodiment is the same as that of Embodiment 1. For the unexplained features in this embodiment, the explanation in Embodiment 1 is adopted. I will not repeat them here. The difference between this embodiment and the first embodiment is that the installation of the frame 12 and the tube box 4 does not require the use of the threaded hole 91 of the tube box end 9. But for reference Figure 5 As shown, the frame 12 is fastened to the outer circle 1 of the tube box end 9 by tightening bolts 21. If necessary, the number of tightening bolts 21 can be appropriately increased depending on the situation of the threaded hole 91 to enhance the connection rigidity.

Abstract

The invention discloses a diaphragm seal weld joint welding machine for a heat exchanger and a welding method. The welding machine comprises a rack arranged at the end of a pipe box, an annular guide rail arranged on the rack and a welding device. Guide rail teeth are arranged on the annular guide rail. The welding device comprises a welding gun frame, a welding gun arranged on the welding gun frame, a wire feeding device and a guide rail gear arranged on the welding gun frame and matched with the guide rail teeth. Under the driving action of a power source, the welding gun rotates along the annular guide rail. Compared with the prior art, the welding efficiency of the welding machine is high, welding and sealing quality consistency is good, weld joints are uniform, the structure is simple, disassembly and assembly are convenient, and meanwhile the assembly quality of the end and an end cover of the pipe box can be improved. The welding method includes the steps that the welding machine is fastened to a threaded hole in the end of the pipe box through a stud nut of the pipe box of the heat exchanger, or the welding machine is fastened to the outer circle face of the end of the pipe box through a tightening bolt. The welding method is simple and easy to operate, can improve assembly and welding quality and is convenient to industrially popularize on a large scale.
