Description

Screw cooling device Technical Field The utility model relates to the technical field of screw cooling, in particular to a screw cooling device. Background In modern industrial production, a screw rod is used as a key component of a mechanical transmission system and is widely applied to the fields of numerical control machine tools, automatic equipment and the like. Along with the continuous improvement of equipment operation speed and precision requirement, the lead screw can produce a large amount of heat at its installation end in the high-speed operation in-process, if not in time dispel the heat, will lead to the lead screw tip to take place the heat altered shape, and then influence the machining precision and the life of equipment. Therefore, an efficient cooling device is important for guaranteeing stable operation of the screw rod. At present, cooling devices for screw ends in the market mostly adopt a cooling liquid circulation mode to dissipate heat. However, this type of device generally has a significant problem in that it is inconvenient to clean the coolant passage. During long-term use, metal scraps, impurity particles carried in the cooling liquid, scale generated by the reaction of chemical components of the cooling liquid with the metal surface and the like gradually adhere to the inner wall of the cooling liquid channel. Over time, these impurities and scale build up, which is very likely to cause clogging of the coolant channels. Once the channel is blocked, the flow of the cooling liquid is greatly reduced, even a local flow break phenomenon occurs, the cooling efficiency is rapidly reduced, the cooling requirement of continuous and stable operation of the screw rod cannot be met, the screw rod is possibly overheated and damaged during severe conditions, the equipment maintenance cost and the downtime are increased, and the continuity and the efficiency of industrial production are affected. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides a screw cooling device, which aims to solve the technical problems that the cooling device for the screw end part is inconvenient to clean a cooling liquid channel and is easy to cause blockage due to impurities and scale in the cooling liquid channel after long-time use, and the circulation of cooling liquid is influenced, so that the cooling effect is reduced.
