Angle-adjustable vertical band sawing machine for end face of steel tube bundle

The utility model belongs to the technical field of band sawing machines, and particularly relates to an angle-adjustable steel tube bundle end face vertical band sawing machine which comprises a machine tool machining table, a T-shaped groove is formed in the upper portion of a body of the machine tool machining table, and an angle fixing clamp and a longitudinal fixing clamp are movably installed on the upper portion of the machine tool machining table. According to the device, the steel pipe is clamped in the transverse direction through the angle fixing clamps, when an included angle is formed between the connecting line between the front side angle fixing clamp and the rear side angle fixing clamp and the T-shaped groove, the included angle and the included angle between the steel pipe and the T-shaped groove are complementary, and therefore the steel pipe can be clamped in the transverse direction. The end face of the steel pipe can be cut into a corresponding angle by changing the included angle betwee
