Gear groove combined male die for warm header

Abstract

The invention discloses a gear groove combined male die for a warm header. The male die comprises a cushion block (1), a punch sleeve (3) and a punch (5), and is characterized in that the punch sleeve(3) is sleeved with the punch (5), the head part of the punch (5) is placed outside the punch sleeve (3), the tail part of the punch (5) is fixedly connected with a fixing sleeve (4), the fixing sleeve (4) is placed on the end face of a step (6) of the punch sleeve (3), the cushion block (1) is pressed at the rear portion of the fixing sleeve (4), a cushion block core (2) is arranged in a cavityof the cushion block (1) and arranged at the tail end of the punch (5), a chamfer is arranged at the tail portion of the punch sleeve (3), an inclination angle is set on the end face of the head part,a step (6) is arranged in the punch sleeve (3), and the punch sleeve (3), the punch (5) and the fixing sleeve (4) are in clearance fit. The male die is economical, adjustable, efficient, durable, convenient to operate, high in quality, stable and suitable for use and popularization for gear groove machining for the warm header.

Description

technical field [0001] The invention belongs to the technical field of moulds, and in particular relates to a gear groove combination positive mold for warm heading machines. Background technique [0002] Fasteners are a type of mechanical parts that are widely used in production and life. In the field of aviation, fasteners have higher requirements. In the production of aviation fasteners, the plum blossom groove is gradually changed to a gear groove. However, the gear groove male mold designed according to the traditional cross groove male mold is formed continuously at high speed on the warm heading machine. The groove head is easily deformed by heat and is subjected to large impact force, so it is not suitable. The main problems are as follows: First, most of the male molds are integrated. , the groove depth cannot be adjusted; second, local damage needs to be replaced as a whole, wasting materials, and the economy is poor; third, the service life is poor; fourth, the c...

Problems solved by technology

However, the gear groove male mold designed according to the traditional cross groove male mold is formed continuously at high speed on the warm heading machine. The groove head is easily deformed by heat and is subjected to large impact force, so it is not suitable. The main problems are as follows: First, most of the male molds are integrated. , the groove depth cannot be adjusted; second, local damage needs to be replaced as a whole, which wastes materials and is economical; third, the service life is poor; fourth, it is necessary to supplement the chamfering of the groove, and the processing is complicated; fifth, the male mold is easy to deform and has poor stability

Many of the above disadvantages have seriously affected the processing of gear grooves
