The first clamping plate is used to clamp the stacked steel pipes tightly, so that the stacked steel pipes are pressed against each other and arranged in a regular pattern; the second fixing component fixes the second clamping plate; in order to clamp the stacked steel pipes tighter, the first driving component drives the movable plate to continue to move toward the steel pipes, and all the second clamping plates cooperate with all the first clamping plates to completely clamp the stacked steel pipes; by setting a plurality of stacked first clamping plates and a plurality of stacked second clamping plates, free clamping can be performed according to the type of clamped steel pipes and the stacking state, without the need to specially set up corresponding clamps for clamping, and the clamping is suitable for clamping a variety of steel pipes, thereby improving the applicability of steel pipe cutting hydraulic machine tools for clamping steel pipes; 2. By setting the first support plate, the second support plate and the third support plate, the gravity of the first group of splints, the second group of splints and the third group of splints are applied to the fixed plate and the movable plate, so as to avoid the gravity of all the splints being applied to the last splint of the fourth group of splints, so that the splints of each group can slide more easily between adjacent splints; because the first support plate, the second support plate and the third support plate are slidably connected to the fixed plate and the movable plate through the first T-block, the sliding direction of the first group of splints, the second group of splints and the third group of splints is stable, and under the restriction of the first support plate, the second support plate and the third support plate, the sliding direction of the fourth group of splints is also stable; 3. When the ends of the first clamping plate and the second clamping plate are required to be close to the circumference of the steel pipe, the third driving assembly drives the second piston to move downward, and the second piston pushes the hydraulic oil in the U-shaped oil storage channel. The hydraulic oil enters each U-shaped oil delivery channel through the connecting channel. The hydraulic oil in the U-shaped oil delivery channel pushes the first piston, and the first piston pushes the sliding rod. The sliding rod pushes the first clamping plate and the second clamping plate to be close to the circumference of the steel pipe. Since the U-shaped oil delivery channel and the U-shaped oil storage channel are connected, it can ensure that the pressure of each first clamping plate and the second clamping plate on the steel pipe is equal.
