Description

Technical Field

[0001] The utility model particularly relates to a tungsten alloy tube spiral hole processing device. Background Art

[0002] Tungsten alloy has the characteristics of high density, high radiation shielding and environmental protection, and is the first choice for manufacturing medical radiation shielding parts. Some medical tungsten alloy tubes need to be provided with multiple spirally evenly arranged through holes on the circumferential outer wall. The through holes can be matched with medical equipment and used for the passage of isotopes.

[0003] When processing the through hole of the above-mentioned tungsten alloy tube, due to the high density and hardness of the tungsten alloy tube, conventional drilling equipment is difficult to use. For example, the Chinese patent application number 201420723202.4 discloses a new type of steel pipe drilling machine with a chuck; the patent clamps the steel pipe with a chuck and realizes the drilling of the steel pipe through the upper drilling machine. However, since the tungsten alloy tube is round, has high density and high strength, the drill bit of the drilling machine cannot instantly drill a small hole in the tungsten alloy rod when it contacts the tungsten alloy tube, and the drill bit is prone to deviation, resulting in drilling failure.

After completing a set of drilling holes, the drill bit moves away from the tungsten alloy tube workpiece, the chuck rotates the angle of the tungsten alloy tube, and the moving table moves a short distance along the axial direction of the chuck, and then the drill bit drills the tungsten alloy tube workpiece again, and the above operation is repeated, so as to process multiple spirally arranged through holes on the tungsten alloy tube workpiece.
