The base 6 can perform linear motion, and the position of the second hydraulic rod 11 can be adjusted to apply thrust to different positions of the rail according to different requirements to perform bending operations. A fixed baffle 19 is provided on the top edge of the rail mounting platform 2, and a movable baffle 8 is provided on the top surface of the rail mounting platform 2 on one side of the fixed baffle 19. The fixed baffle 19 and the movable baffle 8 are used together to clamp the two sides of the rail to be bent. The rail will not deflect during the bending operation, thereby improving stability. A long groove 7 is provided inside the rail mounting platform 2 below the movable baffle 8, and the movable baffle 8 An L-shaped support plate 9 is arranged at the top edge of the rail mounting platform 2 on one side, and two first hydraulic rods 15 are arranged below the transverse surface of the L-shaped support plate 9. The bottom ends of the two first hydraulic rods 15 are both provided with a fixed disc 17. A mold 16 is detachably installed at the bottom of the first hydraulic rod 15. A mounting groove 18 is arranged at the top of the mold 16 near the two first hydraulic rods 15.

[0027] The method of using this embodiment is as follows: the electrical components appearing in this application are all connected to an external power supply when in use. When using the hydraulic benders, one end of the rail to be bent is inserted above the rail mounting platform 2, and then the threaded column 14 is twisted to push the slider 20 to drive the movable baffle 8 to move linearly in the direction of the fixed baffle 19 to clamp both sides of the rail, and then the first hydraulic rod 15 is twisted to make the mold 16 clamp the top of the rail, and finally the second electric push rod 4 drives the base 6 to make the second hydraulic rod 11 be in a predetermined position below the rail, and the second hydraulic rod 11 applies thrust to the rail to bend the rail. If the rail needs to be bent into a U shape, the two sides of the rail can be bent. Both ends extend out of the rail mounting platform 2 and are synchronously bent by the second hydraulic rod 11. When replacing the mold 16, the mold 16 is pushed backward to move the two first hydraulic rods 15 to the rear end position of the two mounting grooves 18, and the mold 16 can be pulled down to remove it. When installing the mold 16, the front end of the mounting groove 18 set at the top of the mold 16 is aligned with the two first hydraulic rods 15, and then the mold 16 is pushed upward to insert the fixed disc 17 into the mounting groove 18, and then the mold 16 is pulled horizontally to move the fixed disc 17 into the mounting groove 18, and the mold 16 is clamped, and then the corresponding detachable limit key is assembled in the mounting groove 18.
