Compared with the prior art, the utility model discloses a tube bank part dip-soldering machine utilizes the great principle of tin self density, carries out the tin soldering through the molten tin suction of tin pump with tin liquid groove below to dipping inslot, avoids impurity to get into the clearance department of copper pipe and tube sheet, improves the dip-soldering quality.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
the tin immersion device comprises a tin liquid tank 1, a tin pump 2, a tin pump 3, a heating pipe 4, an immersion liquid tank 5, a bent pipe 6 and a thermocouple.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below.
As shown in FIG. 1, a tube bundle part dip-welding machine comprises a tin liquid tank 1 and a tin pump 2, wherein the tin pump 2 is arranged in the tin liquid tank 1 through a bracket; a plurality of heating pipes 3 are arranged on one side in the tin liquid tank 1, and the other side is connected with a liquid immersion tank 4; the outlet side of the tin pump 2 is connected with the immersion tank 4 through a bent pipe 5; the heating device comprises a heating pipe 3, a temperature meter, a thermocouple 6, a temperature meter and a temperature controller, wherein the heating pipe 3 is connected with the external temperature meter, the heating pipe 3 is used for heating tin materials in a tin liquid tank 1, molten tin liquid is precipitated due to the fact that tin is high in density, impurities float above the tin liquid, the thermocouple 6 is arranged in the tin liquid tank 1, the thermocouple 6 feeds back the temperature in the tin liquid tank to the temperature meter, and the temperature meter controls the heating temperature of the heating pipe to be 280-320 ℃; the tin pump 2 discharges tin liquid below the tin liquid tank 1, and the tin liquid is sent into the immersion liquid tank 4 through the bent pipe 5.
In this embodiment, the immersion tank 4 is a square shell welded by plates, the top of the immersion tank 4 is open, the height of the left side plate of the immersion tank 4 is lower than that of the right side plate of the immersion tank, the top of the immersion tank 4 is open to facilitate the dip welding of pipe bundle parts, and the heights of the left side and the right side of the immersion tank 4 are not consistent, so that the tin liquid can flow circularly, and the temperature of the tin liquid is kept consistent.
The present invention is not limited to the above-described embodiments, and those skilled in the art can make modifications or changes without departing from the spirit of the present invention.
