Embodiment Construction

[0020] see figure 1 with 2 , a seam welding process for a wire tube evaporator, comprising the following steps,

[0021] ①. Put the iron wire 2 on the wire tube evaporator 1, and there are multiple welding points 6 between the iron wire 2 and the wire tube evaporator 1;

[0022] 2. Place the welding contacts (3 and 4) on the upper and lower sides of the welding point 6 respectively on the upper and lower sides of the iron wire 2, and make it roll along the iron wire 2 through the transmission mechanism until it reaches a welding point 6, Weld once to form welding point 5 (schematic).

[0023] ③, continue to scroll to the next point to be welded, repeat welding;

[0024] ④. Roll to one end of the wire tube evaporator (the last point to be welded in each row), and use the platform propulsion mechanism to make the wire tube evaporator and the iron wire move forward to one end, and the forward displacement is the gap distance between two adjacent rows of iron wire;

[0025] ⑤....

Abstract

The invention belongs to the processing technique of refrigeration industry and particularly relates to a roll welding technology of a wire tube evaporator. In the roll welding technology of the wire tube evaporator, the wire tube evaporator is welded in a rolling way by two welding contacts arranged according to upper and lower mirror images, and positive and negative electrodes are formed at the upper and lower ends, so that the welding operation can be finished without copper plating on the wire tube evaporator to be welded, thereby saving the product cost of the copper plating technology. Meanwhile, the roll welding technology of the wire tube evaporator can realize synchronous processing of two sides, so that the processing efficiency is higher.

Description

technical field [0001] The invention belongs to the processing technology of the refrigeration industry, and in particular relates to a seam welding process of a wire tube evaporator. Background technique [0002] Wire tube evaporators have a wide range of applications in the refrigeration industry. The structure of the existing silk tube evaporator is as follows: figure 1 As shown, multiple groups of iron wires 2 are placed on the wire tube evaporator 1, and multiple connection points (points to be welded) between the iron wires 2 and the wire tube evaporator 1 on the same horizontal line are formed by row welding in one process. The welding current reaches more than 2000A, and the energy consumption is high. [0003] Welding by welding machine, the welding current is the sum of the current of all welding spots under the welding head, so that the current of each welding spot cannot be guaranteed to be uniform, and there will be some welding spots with too much current, wh...
