A non-slip rubber pad 142 is fixedly installed on the left side of the clamping positioning plate 141. A vertical plate 15 is fixedly installed on the front right side of the top of the bending platform 1. A hydraulic telescopic rod 151 is fixedly installed on the left side of the vertical plate 15. A metal bending squeezing ball 152 is fixedly installed on the output end of the hydraulic telescopic rod 151. A bending column 16 is fixedly installed on the front side of the top of the bending platform 1. The right side of the bending column 16 is aligned with the right side of the fixed limiting plate 11. A limiting mechanism 17 is provided on the top of the bending column 16, and a profile pushing mechanism 18 is provided on the left side of the top of the bending platform 1;

[0023] When processing aluminum alloy profiles for fireproof doors and windows, one side of the long profile is pushed forward against the fixed limit plate 11 until the front end exceeds the bending column 16 and exceeds the length required for bending. Then, the servo motor 13 can be directly started to drive the clamping threaded rod 131 in the clamping slide 12 to rotate. The threaded connection between the clamping threaded rod 131 and the clamping drive plate 14 can be used to drive the clamping positioning plate 141 to move to the left, and the anti-slip rubber pad 142 is used to clamp the right side of the profile. The friction resistance of the anti-slip rubber pad 142 is used to improve the stability after clamping. Then, the hydraulic telescopic rod 151 on one side of the vertical plate 15 can be started to drive the metal bending extrusion ball 152 at the output end to move to the left, thereby squeezing the profile part exceeding the bending column 16 to the left until the front end of the profile becomes horizontal, so that the profile is bent into an L shape.

[0024] like Figure 3 、 Figure 4As shown, the limiting mechanism 17 includes an L-shaped vertical plate 171, the bottom of the vertical part of the L-shaped vertical plate 171 is fixedly connected to the top right side of the bending column 16, and an electric push rod 172 is fixedly installed on the horizontal top of the L-shaped vertical plate 171. The output end of the electric push rod 172 passes through the bottom of the horizontal part of the L-shaped vertical plate 171 and is fixedly installed with a pressure plate 173. The profile pushing mechanism 18 includes a driving box 181, and the driving box 181 is fixedly connected to the top of the bending platform 1. A servo motor 2 182 is fixedly installed on the rear side of the driving box 181, and the output shaft of the servo motor 2 182 passes through the inner cavity of the driving box 181 and is fixedly installed with a pushing threaded rod 183. The outer wall of the pushing threaded rod 183 is threadedly installed with a moving plate 184. Push rods 185 are fixedly installed on the left and right sides of the front end of the moving plate 184. The front ends of the two pushing rods 185 both pass through the front side of the driving box 181 and are fixedly installed with a pushing plate 186.

[0025] During the bending process, the electric push rod 172 at the top of the horizontal L-shaped vertical plate 171 is started to drive the pressure plate 173 to move downward, thereby pressing the profiles of different heights to prevent loosening and deviation when squeezed. Finally, the horizontal point of the bent end of the profile will be located in front of the drive box 181. At this time, the clamping state of the clamping positioning plate 141 is released, and the servo motor 2 182 is started to drive the pushing threaded rod 183 in the inner cavity of the drive box 181 to rotate. The threaded connection between the pushing threaded rod 183 and the moving plate 184 can drive the moving plate 184 to drive the two pushing rods 185 to move forward stably, and the pushing plate 186 is used to press against the horizontal point of the bent profile to push the entire profile toward the profile collecting mechanism 2.

[0026] like Figure 5 As shown, the profile collecting mechanism 2 includes a collecting frame 21, which is fixedly installed on the front side of the bending platform 1, and a guide inclined plate 22 is fixedly installed at the rear between the left and right sides of the inner wall of the collecting frame 21, and a side guard plate 23 is fixedly installed on the top right side of the collecting frame 21. A profile collecting drawer 25 is slidably connected to the inner side of the collecting frame 21, and a drop notch groove 1 24 is provided at the front left side of the top of the collecting frame 21, and a drop notch groove 26 is provided at the front right side of the top of the profile collecting drawer 25, and the rear side of the drop notch groove 26 is aligned with the rear side of the drop notch groove 1 24. A pull-out handle 27 is fixedly installed on the front side of the profile collecting drawer 25;

[0027] After the profile is pushed to the top of the collection frame 21, the front end tilts downward under the action of gravity, and is guided by the guide inclined plate 22 to smoothly slide into the profile collection drawer 25 in the inner cavity of the collection frame 21. At the same time, the side guard plate 23 is used to prevent the profile from deviating from the collection frame 21. When the horizontal bent part of the profile is longer, it will first slide on the top left side of the collection frame 21 when it moves to the top of the collection frame 21 until it reaches the position of the drop notch groove 1 24. The horizontal bent part of the profile will directly fall into the drop notch groove 2 26, so that it is placed flatly in the profile collection drawer 25. Similarly, the profile is stacked flatly upward. When the profile collection drawer 25 is almost full, the pull-out handle 27 can be used to pull out the profile collection drawer 25 for easy collection.

[0028] The following is a detailed description of the working principle of the bending device for processing fireproof doors and windows.

[0029] like Figure 1-5As shown, when processing the aluminum alloy profiles of fireproof doors and windows, one side of the long profile is pushed forward against the fixed limit plate 11 until the front end exceeds the bending column 16 and exceeds the length required for bending. Then, the servo motor 13 can be directly started to drive the clamping threaded rod 131 in the clamping slide 12 to rotate. The threaded connection between the clamping threaded rod 131 and the clamping drive plate 14 can drive the clamping positioning plate 141 to move to the left, and the anti-skid rubber pad 142 is used to clamp the right side of the profile. The friction resistance of the anti-skid rubber pad 142 is used to improve the grip after clamping. Stability, then the hydraulic telescopic rod 151 on one side of the vertical plate 15 can be started to drive the metal bending extrusion ball 152 at the output end to move to the left, thereby squeezing the part of the profile that exceeds the bending column 16 to the left until the front end of the profile becomes horizontal, so that the profile is bent into an L shape. At the same time, during the bending process, the electric push rod 172 at the top of the horizontal part of the L-shaped vertical plate 171 can be used to drive the pressing plate 173 to move downward, and the profiles of different heights are pressed to prevent loosening and deviation when squeezed. Finally, the horizontal part of the bent end of the profile will be located in front of the drive box 181 At this time, the clamping state of the clamping positioning plate 141 is released, and the servo motor 2 182 is started, which can drive the pushing threaded rod 183 in the inner cavity of the driving box 181 to rotate. The threaded connection between the pushing threaded rod 183 and the movable plate 184 can drive the movable plate 184 to drive the two pushing rods 185 to move forward stably, and use the pushing plate 186 to push the profile forward against the horizontal part of the bending of the profile until the profile reaches the top of the collection frame 21. The front end tilts downward under the action of gravity, and the profile slides smoothly into the inner cavity of the collection frame 21 under the guidance of the guide inclined plate 22. The side guard plates 23 are used to prevent the profiles from deviating from the collection frame 21. When the horizontal part of the bent profile is longer, it will slide on the left side of the top of the collection frame 21 when it moves to the top of the collection frame 21 until it reaches the position of the drop notch groove 1 24. The horizontal part of the bent profile will fall directly into the drop notch groove 2 26, so that it can be placed flatly in the profile collection drawer 25. Similarly, the profiles can be stacked flatly upwards. When the profile collection drawer 25 is almost full, the pull-out handle 27 can be used to pull out the profile collection drawer 25 for easy collection.

[0030] While the present invention has been generally described above, it is readily apparent to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are intended to be within the scope of protection of the present invention.
