Problems solved by technology

However, the existing twist drill production process for obtaining helical double oil holes usually applies torque directly at both ends of the drill pipe, and the resulting drill pipe has uneven longitudinal torsion, and the helix angle varies greatly in the length direction of the drill pipe. , very low accuracy

Abstract

The invention discloses a drill rod torsion device, which comprises a driving motor, a transmission device, a translation device, a chuck used for clamping the drill rod, and a heating coil wound on the drill rod, wherein the transmission device is provided with a first output shaft and a second output shaft, the driving motor is connected with the translation device, the chuck is arranged at the end part of the first output shaft, the translation device is connected with the second output shaft, the translation device thereon is provided with a spiral mold which is arranged between the chuck and the heating coil, and the central line of the spiral mold and the rotation axis of the chuck are coaxially arranged along the translational direction of the translation device. The drill rod torsion device has the advantages of simple structure, capability of uniform torsion and high precision of torsion shaping.

Description

technical field [0001] The invention relates to twist drill manufacturing equipment, in particular to a drill pipe twisting device. Background technique [0002] In the machining industry, a drill bit is a tool that is often used, and the most commonly used one is a twist drill. In order to improve the drilling performance and service life of twist drills, in addition to heat treatment, surface titanium plating, polishing, and nitriding, improving the cooling method has become a problem that cannot be ignored. Traditional twist drills must be directly sprayed with coolant during the cutting process. On the drill bit, when the drilling depth reaches 30 mm, the cooling is extremely insufficient, and the cutting edge of the drill bit is hardly cooled. In order to make the drill bit work normally, the operator must withdraw the drill bit frequently and continue drilling after cooling down, so the cutting speed is slow, the efficiency is low, the drill bit wears quickly, the lif...
