Description

Barrel broaching machine < RTI ID = 0.0 >

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a total heat broaching apparatus, and more particularly, to a total heat broaching apparatus in which a total heat broaching tool is inserted into a through hole of a material and pulled in one direction to form a steel wire on the inner circumferential surface of the through hole.

Generally, the helical groove inside the gun column is called a rifling, and it gives rotation and stability of the orbit and the destructive power of the bullet. As described above, the steel wire is introduced to impart a rotational inertia to the bullet so as to have a stable trajectory and to increase the destructive force.

The steel wire has a concave and convex structure made of mountains and cores and is spirally processed in the inside of the barrel. It can be machined by a rotary drill that cuts a helical groove on the inside of the barrel, but it is produced by press processing using strong force and heat in the present mass production system.

A method of forming a glow wire to form a spiral steel wire in such a gutter is disclosed in Korean Utility Model Laid-Open No. 20-2009-0001951.

The life span of the above-mentioned life span has a concavo-convex structure composed of mountains and cores, and is spirally processed inside the total heat. It can be machined by a rotary drill that cuts a helical groove on the inside of the barrel, but it is produced by press processing using strong force and heat in the present mass production system.

Therefore, residual stresses and initial cracks may occur at the boundary of the steel wire during the manufacturing process, and cracks may be enlarged due to tensile load if the shot is repeatedly fired.

Further, the steel wire formed by the rotary drill and the press working takes a long time to be machined, and there is a problem that the machining precision is poor and many defects occur.
