Smoothening and cooling device special for combined welding of steel tube and capillary tube

Abstract

The invention discloses a smoothening and cooling device special for combined welding of a steel tube and a capillary tube. The smoothening and cooling device is characterized in that the device comprises a smoothening mechanism and a circulating cooling device; the smoothening mechanism is composed of positioning stand plates, clamping springs, motors, air cylinders, electromagnetic valves, fixing plates, bearings each provided with a ball disc, bearing sleeves, an upper roller and a lower roller; and the circulating cooling device comprises a water storing tank, a water pump, a water outlet pipe, side plates, a water tray, a water return pipe and a control switch. By means of the smoothening and cooling device special for combined welding of the steel tube and the capillary tube, the steel tube and the capillary tube on which combined welding is just finished through tin welding wires can be smoothened to be straight, and meanwhile, the welding position of the steel tube and the capillary tube can be cooled, so that the production efficiency is high, the cooling effect is good, the smoothened steel tube and the smoothened capillary tube are straight, and the smoothening and cooling device is suitable for being widely applied and popularized during combined welding of the steel tube and the capillary tube through the tin welding wires.

Description

technical field [0001] The invention relates to the technical field of a push-up cooling device for parallel welding, and specifically belongs to a special push-up cooling device for parallel welding of steel pipes and capillary tubes. Background technique [0002] In the manufacturing process of the evaporator, it is necessary to weld the capillary and the steel pipe together through the tin welding wire. When welding, first put the steel pipe and the capillary on the roller, install the coiled tin welding wire, and pull out one end of the welding wire to align it with the steel pipe. At the place to be welded between the capillary and the capillary, point the gas torch at the place to be welded between the welding wire and the capillary of the steel pipe, and the melted welding wire drops into the place to be welded. There are some problems in this process: 1. Sometimes the melted welding wire drips onto the steel pipe or capillary, and does not flow into the place to be w...

AI Technical Summary

Problems solved by technology

There are some problems in this process: 1. Sometimes the melted welding wire drips onto the steel pipe or capillary, and does not flow into the place to be welded; Rapid cooling ensures that the steel pipe and capillary are tightly bonded. If rapid cooling is not possible, the steel pipe and capillary will be desoldered at the place to be welded; in order to solve these two problems, the steel pipe and capillary are now welded together by manually grabbing a wet cloth. Manual cooling, there are the following serious problems at this time: 1. The melted welding wire often drips onto the hands of employees, causing employees to be scalded; Seriously affect production efficiency; 3. Sometimes employees forget to dip the cloth in time to take water, causing the cloth to be ignited by the dripping welding wire or the cloth is too dry to play a cooling role, resulting in batch desoldering of steel pipes and capillary welds
