[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 As shown, the utility model provides a technical solution:

[0022] Embodiment 1: A roller-type aluminum profile bending mold comprises an upper mold 1, a lower mold 2 and a roller body 4, a bending protrusion 11 is arranged at the bottom of the upper mold 1, a bending groove 21 is opened at the top of the lower mold 2, and the bending groove 21 is matched and connected with the bending protrusion 11, and a circular arc groove 22 is symmetrically opened at the top of the lower mold 2 near the bending groove 21, and the roller body 4 is placed in the circular arc groove 22, and a pressure seat 3 is symmetrically arranged on the lower mold 2 on both sides of the bending groove 21, and the pressure seat 3 is arranged in the groove opened at the top of the lower mold 2, and the top of the pressure seat 3 is flush with the top of the lower mold 2, and the two sides of the pressure seat 3 slide along the inner wall of the groove, When the screw 5 rotates, the pressure seat 3 can move up and down, and an arc surface 31 is provided at a position close to the arc groove 22 on the pressure seat 3, and the arc surface 31 is fitted with the outer wall of the roller body 4. By fitting the arc surface 31 on the pressure seat 3 with the outer wall of the roller body 4 and cooperating with the arc groove 22, the roller body 4 can be prevented from detaching from the arc groove 22. When the aluminum profile is bent, the roller body 4 can reduce the strain at the bending part of the aluminum profile and reduce the friction. The interior of the lower mold 2 is rotatably connected to a worm 7 through a bearing, and one end of the worm 7 extends to the outside of the lower mold 2 and is fixedly connected to an adjustment handle 71. The interior of the tool 2 is symmetrically rotatably connected with a screw rod 5 through a bearing, and the lower ends of the two screw rods 5 are sleeved and fixed with a worm wheel 6, and the two worm wheels 6 are transmission-connected with a worm 7. The upper ends of the two screw rods 5 are respectively threaded into the threaded holes at the bottom of the two pressure seats 3. By rotating the worm 7 to drive the two screw rods 5 to rotate, the two pressure seats 3 can be driven to move upward or downward synchronously, so that personnel can easily install and disassemble the roller body 4 and replace the roller body 4. When in use, when bending the aluminum profile, the aluminum profile can be bent by cooperating with the bending protrusion 11 and the bending groove 21. During the bending process, the roller body 4 can bend the aluminum profile with the lower mold. 2 is converted into rolling friction, reducing the friction of the aluminum profile. After a period of time, when the roller body 4 needs to be replaced, the worm 7 can be driven to rotate by manually rotating the adjusting handle 71 counterclockwise. The rotation of the worm 7 can drive the worm wheel 6 together with the screw 5 to rotate. The rotation of the screw 5 can drive the pressure seat 3 to move upward. At this time, the roller body 4 can be taken out of the circular arc groove 22, and then the new roller body 4 is replaced in the circular arc groove 22, and the adjusting handle 71 is rotated clockwise to drive the pressure seat 3 to reset downward, so that the circular arc surface 31 is effectively in contact with the outer wall of the roller body 4, and the roller body 4 can be quickly replaced.

[0023] Embodiment 2: The difference between this embodiment and embodiment 1 lies in that, an annular limiting groove 41 is provided in the middle of the roller body 4, a lower arc-shaped protrusion 23 is provided in the middle of the circular arc groove 22, and the lower arc-shaped protrusion 23 is matched and connected with the annular limiting groove 41, and an upper arc-shaped protrusion 32 is provided in the middle of the circular arc surface 31, and the upper arc-shaped protrusion 32 is matched and connected with the annular limiting groove 41. By matching the lower arc-shaped protrusion 23 with the annular limiting groove 41, and matching the upper arc-shaped protrusion 32 with the annular limiting groove 41, the front and rear directions of the roller body 4 can be limited to prevent the roller body 4 from moving forward and backward during rolling, so that the roller body 4 can stably roll in the arc groove formed by the circular arc groove 22 and the circular arc surface 31.

[0024] Working principle: When using, when bending the aluminum profile, the aluminum profile can be bent by the cooperation of the bending protrusion 11 and the bending groove 21. During the bending process, the roller body 4 can convert the sliding friction between the aluminum profile and the lower mold 2 into rolling friction, reducing the friction of the aluminum profile. During the rolling process of the roller body 4, the lower arc protrusion 23 and the upper arc protrusion 32 can limit the front direction of the roller body 4 to prevent the roller body 4 from moving forward and backward. After a period of time, when the roller body 4 needs to be moved When replacing, the worm 7 can be driven to rotate by manually turning the adjusting handle 71 counterclockwise. The rotation of the worm 7 can drive the worm wheel 6 and the screw 5 to rotate together. The rotation of the screw 5 can drive the pressure seat 3 to move upward. At this time, the roller body 4 can be taken out from the arc groove 22, and then the new roller body 4 is replaced in the arc groove 22, and the adjusting handle 71 is turned clockwise to drive the pressure seat 3 to move downward to reset, so that the arc surface 31 is effectively in contact with the outer wall of the roller body 4, and the roller body 4 can be quickly replaced.
