A punch head lubrication mechanism

ActiveCN111957814BReduce frictionTo avoid glitchesShaping toolsMetal-working feeding devicesPunchingStructural engineering
The invention relates to the field of stamping dies, in particular to a lubricating mechanism for a stamping head, including a base, a stamping structure, a lubricating structure, a guiding structure, a feeding structure, a cleaning structure and a pressing structure; Punch out the required circular parts one by one, and when the punching structure is punching, it can synchronously drive the lubricating structure to work. Through the work of the lubricating structure, it can automatically clean the components inside the stamping structure during stamping. Oil injection lubrication works, so as to reduce the friction between the stamping components and the sheet material, and avoid burrs around the punched finished parts, so as to greatly improve the production quality. While the feeding structure is working, it can also be synchronized Drive the cleaning structure to work, through the work of the cleaning structure, the dust and debris on the metal sheet to be punched can be blown off, so as to prevent dust and impurities from being punched together with the metal sheet.
