Description

Technical Field

[0001] The utility model belongs to the technical field of machining and welding, and relates to a cooling device for parts used in machining and welding. Background Technique

[0002] The disadvantages of existing machining and welding equipment in the welding and cooling of tubular parts are mainly reflected in uneven temperature control, large heat affected zone, welding deformation, and difficulty in precisely controlling the cooling rate. The reasons for these disadvantages lie in the concentrated input of heat during the welding process and the subsequent heat dissipation process. Due to the special shape of the tubular structure, uneven heat distribution and inconsistent heat dissipation lead to the above problems. The cooling system design of the welding equipment may not be optimized for the special shape and size of the tubular parts, thus unable to achieve precise temperature management.

[0003] Conventional countermeasures include using water-cooling or air-cooling systems to accelerate the cooling process, and adopting preheating and post-heat treatment to reduce thermal stress and deformation. The drawbacks of these methods are that they may not completely solve the problem of uneven temperature distribution. Preheating and post-heat treatment increase the process complexity and production cost. At the same time, the water-cooling system may cause uneven cooling inside the tubular parts, resulting in internal stress and deformation. Although the air-cooling system is simple, its cooling efficiency is relatively low, and it is highly dependent on the ambient temperature and wind speed, making it difficult to ensure the stability and repeatability of the cooling process. Therefore, there is an urgent need for a cooling device for parts used in machining and welding to solve the above problems. Summary of the Utility Model
