[0002] The cold heading machine is the main equipment for mass-producing rivet nuts. When producing rivet nuts, the cold heading machine first cold-heads the section steel into the blank of the rivet nut, and then threads the inner hole of the blank on the tapping equipment to process it into a rivet nut. During the cold heading process, the lubricating oil in the oil storage tank of the cold heading machine is required to lubricate the die and the blank of the rivet nut, so as to protect the die and facilitate the stretching of the steel. In this way, there is a lot of lubricating oil on the blank of the rivet nut.
