Description

Technical Field

[0001] The invention relates to the technical field of hot melt drilling processing, in particular to a hot melt drilling processing center with an automatic hot melt oil spraying mechanism. Background Art

[0002] High-temperature chipless forming and friction hot melt drilling technology, referred to as hot melt drilling technology, is a new type of thin plate drilling method. It uses the basic physical principle of frictional heat generation. When the high-speed rotating drill bit contacts the workpiece surface and applies downward axial pressure, the hot melt drill head rubs against the metal and generates a high temperature of 650℃~750℃, which rapidly softens the metal in the area near the hot melt drill bit. While the hot melt drill squeezes and penetrates, it stretches the softened metal part into a metal boss (boss) three to four times the original thickness, and drills a hole with a boss on a plate or tube metal workpiece, forming it in one step without generating drill chips. This process completely replaces the process of welding (riveting) nuts on thin-walled workpieces.

[0003] However, if the high temperature generated by the friction of the drill bit during the processing of the workpiece in the existing hot melt drilling processing center exceeds the specified range, it will easily lead to a decrease in the hardness of the drill bit, aggravated wear and even affect the service life of the drill bit. The usual equipment uses air cooling to directly blow the drill bit to cool it, resulting in poor heat dissipation effect of the drill bit. Summary of the invention
