摘要： PURPOSE: A pipe shear device in a blow-out preventing device, a shear ram assembly for the blow-out preventing device, and an attachment method for a shear blade are provided to improve rigidity of a shear blade by preventing the surface reduction in the front surface of the shear blade. CONSTITUTION: A pipe shear device in a blow-out preventing device comprises a shear ram block (13), a blade (17), a plurality of face bolt passages (20), a face bolt, one or more inclined bolt passages (28), and an inclined bolt (26). The shear ram block comprises a front end and a longitudinal axis. The blade comprises a front surface (23) and a rear surface. The front surface is formed on the opposite side of the front surface and is connected to the front end of the shear ram block. The face bolt passages penetrate the blade and are extended to the inside of the front end of the shear ram block. The face bolt passages are parallel to each longitudinal axis. The face bolt is located in each face bolt passage and fixes the blade to the shear ram block. The inclined bolt passages are connected to the lower inside from the upper surface of the shear ram block and are extended to the inside of the blade. The inclined bolt is inserted into the inclined bolt passages and fixes the blade to the shear ram block.
