Before the profile is bent, it is flat on the lower die 34. When the bending starts, its end will be embedded in the lower die 34, so that the free end is tilted. Therefore, during bending, the auxiliary lifting assembly 4 can support the profile when it is tilted, so as to avoid the deadweight of the free end of the profile affecting the bending effect; The bending mechanism 2 5 is arranged on the bracket 2. After one end of the workpiece is bent, the other end of the workpiece can be bent. After the first bending is completed, the cylinder body 31 maintains this state, and then the bending mechanism 2 5 can bend the other side of the profile. In this process, the bending mechanism 1 3 can not only fix the profile, but also maintain pressure during the maintenance process, so that the molding effect is better.

[0019] Slide grooves 6 are provided on both sides of the bracket 2, and sliders 7 are provided at both ends of the mounting plate 32. The sliders 7 are slidably set in the slide grooves 6, and the two ends of the mounting plate 32 are slidably set on the bracket 2 through the sliders 7 to ensure that the mounting plate 32 is more stable when sliding.

[0020] The auxiliary lifting assembly 4 is provided with two groups and is respectively provided on both sides of the bracket 2. The auxiliary lifting assembly 4 includes a rotating shaft 41 rotatably provided at the bottom of the side of the bracket 2, a rotating rod 42 is fixedly provided at the end of the rotating shaft 41, an elastic member 43 is provided at the end of the rotating rod 42, the bottom end of the elastic member 43 is connected to the rotating rod 42 and the top end is provided with a pressing mold 44, and a transmission member 8 is provided on the outer side of the rotating shaft 41 and is transmission-connected thereto, and the transmission member 8 is transmission-connected to the slider 7; When the cylinder body 31 is extended, the mounting plate 32 moves downward to drive the slider 7 downward, and the slider 7 drives the transmission member 8 to drive the rotating shaft 41 to rotate, thereby driving the rotating rod 42 and the die 1 44 to rotate and follow the tilting of the profile to support it.

[0021] The transmission member 8 includes a sleeve 81 rotatably arranged at the bottom of the side of the bracket 2, the sleeve 81 is sleeved on the outside of the rotating shaft 41, the end of the sleeve 81 is connected to a gear 82, a connecting rod 83 is arranged on the slider 7, and a rack 84 meshing with the gear 82 is arranged at the bottom of the connecting rod 83, and a driving frame 85 is arranged on the outside of the sleeve 81.

When bending, there is a certain distance between the bottom of the bending knife 33 and the top of the lower die 34. When the bending knife starts to move down, the profile remains stationary in this stroke. Only when the bending knife 33 starts to abut the profile and presses it into the lower die 34, the bending starts. Therefore, the driving frame 85 is arranged on the outside of the sleeve 81 through the spline. When in use, the driving frame 85 can be slid out of the spline range, and then the driving frame 85 can be adjusted. 5 with the horizontal direction, so that when the rack 84 drives the gear 82 to rotate, the gear 82 drives the driving frame 85 to rotate a certain angle first, and this process corresponds to the distance between the bending knife 33 and the surface of the profile. When the bottom end of the bending knife 33 begins to contact the profile, the driving frame 85 just abuts against the rotating rod 42 to make it rotate, thereby achieving support for the tilting of the profile.

In actual use, each die can be replaced according to the size of the profile to be bent and the bending angle to adapt to the profile.

[0025] A rotating seat 9 is fixedly provided on the top of the connecting frame 57, and the rotating seat 9 is installed on the transverse block 55 by bolts, so that the angle of the connecting frame 57 on the transverse block 55 can be adjusted. According to different bending angles of the profile, the direction of the connecting frame 57 also needs to be changed accordingly, so the connecting frame 57 is movably set on the transverse block 55.
