A kind of supporting cooling device specially used for parallel welding of steel pipe and capillary tube

Abstract

The invention discloses a special lifting and cooling device for parallel welding of steel pipe and capillary tube, which is characterized in that it comprises a lifting mechanism and a circulating cooling device, and the lifting mechanism has a positioning vertical plate, a retaining spring, a motor, a cylinder, a solenoid valve, and a fixing plate 1. Bearings with marble discs, bearing sleeves and upper and lower rollers. The circulating cooling device includes water storage tanks, water pumps, outlet pipes, side plates, water trays, return pipes and control switches. The invention can straighten the steel pipe and the capillary that have just been welded with tin welding wire, and at the same time cool the welded part of the steel pipe and the capillary, with high production efficiency and good cooling effect. The straightened steel pipe and capillary are suitable for steel pipe and capillary It is widely used when the capillary is welded with tin welding wire.

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
