Abstract
The utility model discloses a tool for processing inner hexagonal blind holes, which comprises a base, a positioning sleeve and a locking nut; a groove is formed in the middle of the upper end face of the base; the positioning sleeve is sleeved outside a processed product and is placed in the base groove in a clearance fit manner; the locking nut is in threaded connection with the upper end of the base; the tool for processing the inner hexagonal blind hole is also provided with a matched hexagonal punching needle for punching the inner hexagonal blind hole. The utility model discloses, adopt and do not have the interior hexagonal of extruded mode die-cut, through the hexagonal towards the product in the hexagonal blind hole of die-cut acquisition, the precision size of hexagonal in can the effective control has not only reduced the defective rate of product processing, has improved machining efficiency simultaneously, adapts to batch production.
Description
Technical Field
The utility model relates to a blind hole processing field especially relates to a frock that is used for interior hexagonal blind hole to process.
Background
The processing method of the inner hexagonal blind hole in the prior art comprises cold forging, hot forging, electric spark and the like, but for Ti6Al4V titanium alloy high-strength and high-hardness materials, a cold forging forming mode cannot be adopted to process a product, particularly the inner hexagonal blind hole. The utility model discloses, adopt and do not have the interior hexagonal of extruded mode die-cut, through the hexagonal towards the product in the hexagonal blind hole of die-cut acquisition, the precision size of hexagonal in can the effective control has not only reduced the defective rate of product processing, has improved machining efficiency simultaneously, adapts to batch production.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a frock for processing of interior hexagonal blind hole to solve the problem that proposes among the above-mentioned background art.
A tool for processing an inner hexagonal blind hole comprises a base, a positioning sleeve and a locking nut; a groove is formed in the middle of the upper end face of the base; the positioning sleeve is sleeved outside a processed product and is placed in the base groove in a clearance fit manner; the locking nut is in threaded connection with the upper end of the base; the tool for processing the inner hexagonal blind hole is also provided with a matched hexagonal punching needle for punching the inner hexagonal blind hole.
After the base is fixed on a punching machine, a product is sleeved on the positioning sleeve and placed in the base, the positioning sleeve and the product are fixed on the base through the locking nut, the punching machine is started, and the product is punched through the hexagonal punching needle.
Preferably, the hexagonal punch pin is made of M42 high-speed steel materials, and the heat treatment hardness is 60-65 HRc.
