[0022] In this embodiment, the mold table 7 is movably rotatably arranged between the inner walls on both sides of the frame 1 through the rotating shaft 9. The bending angles of the four bending grooves 8 are different. The bending grooves 8 with different angles can be switched by rotating the mold table 7, reducing the operation of changing molds.

[0023] In this embodiment, the rotating block 10 is arranged to rotate synchronously with the mold table 7 through the rotating shaft 9, the diameter of the positioning hole 11 and the diameter of the screw 14 are arranged to match each other, and the mold table 7 is rotated by rotating the first turntable 12 to switch the bending slot 8.

[0024] In this embodiment, the screw 14 penetrates the interior of the fixing block 13 in a threaded connection, and the screw 14 is inserted into the positioning hole 11 in a clamping connection. The screw 14 is inserted into the positioning hole 11 to improve the fixation of the mold table 7.

[0025] In this embodiment, the adjustment component 6 includes a support plate 16, which is fixedly installed on the rear part of the frame 1, and a baffle 17 is slidably installed on the top of the support plate 16. A transmission block 18 and two guide blocks 19 are respectively installed at the bottom of the baffle 17 near the middle and both ends and passing through the top of the support plate 16. An adjustment rod 20 is movably installed through the front and rear parts of the transmission block 18, a guide rod 21 is installed through the front and rear parts of the guide block 19, and a rotating rod 22 is movably installed through the front and rear parts of the frame 1 near the bottom end. The rear ends of the rotating rod 22 and the adjusting rod 20 are both installed with rotating teeth 23, and the front end of the rotating rod 22 is installed with a second turntable 24. The length required to be bent is adjusted by sliding the baffle 17 back and forth.

[0029] The utility model sets a mold changing component 5, and the mold table 7 is located on the inner side of the frame 1 and rotates. Through the four bending grooves 8, it is convenient to quickly switch the bending grooves 8 with different bending angles, reduce the operation of replacing the mold, and is suitable for bending at different angles. The screw 14 slides downward through the thread and engages with the positioning hole 11, which is convenient for fixation after rotation and improves the stability of the mold table 7; by setting the adjustment component 6, the rotating rod 22 drives the adjusting rod 20 to rotate through the engagement of the rotating teeth 23, so that the transmission block 18 slides, and then the baffle 17 slides, which is convenient for adjusting the bending position, and can enable the steel template to be quickly placed and bent.
