Problems solved by technology

[0004] At present, in the field of friction stir welding, there are some methods of spraying cooling liquid / cooling gas to cool the surface of the weld seam, but these technologies have limited influence on the temperature distribution of the center of the weld seam and the lower surface; and in terms of control It is difficult to achieve fine and precise control of the cooling rate, so it is impossible to achieve a uniform distribution of the welding temperature field on the thickness

Abstract

The invention discloses a cooling system for friction stir welding. The cooling system comprises a fixing table, a first liquid spraying part, a second liquid spraying part and a adjusting and controlling device, wherein the fixing table is used for fixing a workpiece to be welded; each of the first liquid spraying part and the second liquid spraying part is provided with a plurality of nozzles capable of being connected with a cooling liquid source on the upper side and the lower side of the fixing table, and the liquid spraying directions of the nozzles located on the upper side and the lower side of the fixing table are vertically opposite; the nozzles of the first liquid spraying part are single-hole nozzles, and the nozzles of the second liquid spraying part are multi-hole nozzles; and the adjusting and controlling device comprises an angle adjusting and controlling part and a height adjusting and controlling part, the angle adjusting and controlling part can adjust and control the angles of the nozzles of the first liquid spraying part and / or the second liquid spraying part, and the angle adjusting and controlling part can adjust and control the heights of the nozzles of the first liquid spraying part and / or the second liquid spraying part. The invention further provides a using method of the cooling system, the cooling speed can be accurately controlled, the medium-thickness workpiece can be rapidly cooled in the thickness direction during friction stir welding, temperature distribution is uniform, and therefore the good mechanical property is obtained.

Description

technical field [0001] The invention relates to the technical field of friction stir welding, in particular to a cooling system of friction stir welding and a use method thereof. Background technique [0002] Friction stir is a unique welding technology. The welding head includes a main shaft, a shaft shoulder and a rotating stirring head. The outer diameter of the stirring head is smaller than the shaft shoulder. Fit on the surface of the workpiece; through the high-speed rotation of the stirring head and the friction with the workpiece, the temperature of the rubbed part of the workpiece will increase and soften, and at the same time, the softened part will be stirred to complete the connection of the joint of the workpiece; the shaft shoulder will rub against the surface of the workpiece Heat generation can prevent overflow of plastic state material and remove surface oxide film. Friction stir has the advantages of low residual stress, not easy to deform the welding work...
