Description

Be used for drilling of car front axle with drill bit from fixing device that polishes

Technical Field

The invention relates to the technical field of automobile forging production equipment, in particular to a drill bit self-polishing fixing device for drilling an automobile front axle.

Background

The forging is a processing flow. Forgings are items of metal that are stressed to shape by plastic deformation into a desired shape or suitable compressive force. This force is typically achieved by using a hammer or pressure. The forging process builds a fine grain structure and improves the physical properties of the metal. In the practical use of the components, a correct design enables the particle flow to be in the direction of the main pressure. Forgings require that each piece be uniform without any porosity, inclusions or other imperfections. The strength to weight ratio of the components produced by this method is high. The forging has the advantages of extendable length; a collapsible length, an expandable cross-section; variable length, variable cross-section.

In the production process of the forged piece, the forged piece needs to be punched, the abandonment rate of the drill bit is always high or small during punching, so that extra expenditure is brought to production, in order to save the extra expenditure, a worker can automatically grind the drill bit for production and use through the existing equipment, but the existing self-grinding drill bit has the problem of unstable fixation.
