      Mechanical External Cutter

      Technical Features

      WD-J type is are automatic spring-fed cutters that provide fast, efficient,

      External cutting and recovery of long sections of tubing, drill pipe, casing, and the corresponding size pipe fish. The spring-fed feature prevents excessive strain from being applied from the rig floor, which could cause the knives to burn or break.

      Work Principle

      After the tool connected with the wash over pipe under to the predetermined cutting position, lift the cutter, the spring dog inside the cutter on the preload sleeve withstands the shoulder of fish sub.

      If we continue to lift, the body through shear pins impels feed ring together upward movement, the spring stress compression, When the lift force over shear pins load, shear pins cut off .The spring impels the feed link downward movement: and it could let the knives rotary to the cutter center. Rotary tool, the spring impels the feed ring gradually downward to feed knives with the function the spring elastic potential energy, until the fish cut off, after cut off the fish, the preload sleeve card tight wrap catches the fish which cuts off to extract together.
