Description

Technical Field

[0001] The utility model relates to the technical field of bench drills, in particular to a bench drill cooling device. Background Art

[0002] A bench drill is a machine tool used for drilling operations. It is mainly composed of a bed, a spindle, a feed device, a workbench and other parts. It can be used to process metal materials such as steel, iron, aluminum, etc. It can perform operations such as drilling, reaming, and expanding. In the machinery manufacturing industry, bench drills are often used to process holes in parts. They can also be used in automobile maintenance, such as drilling thread repairs, base hole processing and other operations. In short, bench drills have important applications in various industries and fields that require drilling processing, and are widely used in metal processing, machinery manufacturing, automobile maintenance and other industries.

[0003] When a bench drill performs a long-term, high-speed or heavy-load drilling operation, a large amount of frictional heat will be generated, which may cause the drill bit to overheat, affect the drilling quality and life, and even damage the drill bit. In order to prevent overheating, cooling is one of the common methods. The purpose of cooling is to cool the drill bit and the workpiece by introducing a coolant or lubricant, and reduce frictional heat. The existing cooling method is often to spray coolant on the drill bit and the workpiece through the coolant nozzle around the drill bit to reduce the temperature and flush the debris. By introducing coolant or lubricant in the cutting area, friction and heat are reduced, and cutting lubrication is provided at the same time. Cooling can effectively reduce frictional heat, protect the drill bit, and improve drilling quality and tool life. This method has a simple structure, but its heat dissipation method is single, which easily leads to low heat dissipation efficiency. Therefore, it is necessary to design and modify the cooling device of the bench drill to effectively prevent the phenomenon of low heat dissipation efficiency. Utility Model Content
