Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy bending machines, in particular to a bending machine for producing aluminum alloy doors and windows. Background Art

[0002] Aluminum alloy doors and windows need to be bent during production because bending can make them more beautiful and more in line with design requirements; at the same time, bending can also make them stronger and more stable. Specifically, bending can process flat aluminum alloy materials into shapes with different angles and curvatures. In addition, bending can also help enhance the rigidity and strength of aluminum alloy doors and windows, so that they can better withstand external weight, impact and load. At the same time, bending can also avoid cracks and deformation of door and window parts, and extend the service life and performance of doors and windows.

[0004] Although this patent has the effect of bending aluminum alloy doors and windows when in use, it cannot adjust the distance between two adjacent first driving rollers when in use. This will cause the device to only be able to process aluminum alloy doors and windows of fixed width, which has certain limitations. Utility Model Content

[0028] The height adjustment assembly includes forward and reverse threaded rods 3, threaded blocks 4, trapezoidal blocks 5 and a hand-turned handle 18. The forward and reverse threaded rods 3 are installed in the guide groove 2 for transverse rotation, and the threaded blocks 4 are threadedly connected to the two ends of the outer sides of the forward and reverse threaded rods 3. Trapezoidal blocks 5 are installed on the tops of the threaded blocks 4. A hand-turned handle 18 is installed on the outer side of the bending box 1 for transverse rotation, and the hand-turned handle 18 is used to drive the forward and reverse threaded rods 3 to rotate.

[0029] Specifically, when it is necessary to adjust the height of the first rotating wheel 8 up and down, the rotating hand handle 18 is raised to drive the positive and negative threaded rods 3 to rotate. During the rotation of the positive and negative threaded rods 3, the threaded blocks 4 threadedly connected on both sides of the positive and negative threaded rods 3 are driven to approach each other. The two threaded blocks 4 approach each other and then drive the two trapezoidal blocks 5 to approach each other. The two trapezoidal blocks 5 approach each other and then push the lifting plate 7 upward. By adjusting the distance between the first rotating wheel 8 and the second rotating wheel 9, the transportation and bending of materials of different thicknesses can be achieved.

[0030] Furthermore, a plurality of circular grooves 16 are vertically opened at the bottom of the bending box 1, and a guide column 6 is slidably inserted into each circular groove 16, and the top of the guide column 6 is connected to the bottom of the lifting plate 7;

[0031] Specifically, when the lifting plate 7 moves up and down, a plurality of guide posts 6 vertically installed at the bottom of the lifting plate 7 slide in the circular groove 16, thereby guiding the lifting plate 7 moving up and down and improving the stability of the lifting plate 7 moving up and down.

[0032] Furthermore, rollers 17 are rotatably mounted at both ends of the bottom of the lifting plate 7;

[0033] Specifically, when the two trapezoidal blocks 5 approach each other and push the lifting plate 7 to move up and down, the rollers 17 rotatably installed at the bottom of both sides of the lifting plate 7 come into contact with the bottom of the trapezoidal blocks 5, thereby reducing the friction between the lifting plate 7 and the trapezoidal blocks 5 and increasing the service life of the lifting plate 7 and the trapezoidal blocks 5.

[0034] Furthermore, two support plates 10 are vertically installed at the bottom of the bending box 1, and a rolling wheel 11 is rotatably installed on the top of each support plate 10;

[0035] Specifically, after the material moves to the top of the two rolling wheels 11, the material is bent. After the bending is completed, the first hydraulic rod 12 is started to drive the cutter 14 to cut the material.

[0036] Furthermore, the bending assembly includes a second hydraulic rod 13 and a bending head 15. The second hydraulic rod 13 is vertically installed at the top of the bending box 1, and the bending head 15 is installed at the output end of the second hydraulic rod 13.

[0038] Furthermore, a first hydraulic rod 12 is vertically installed at the top of the bending box 1, and a cutter 14 is installed at the output end of the first hydraulic rod 12;

[0039] Specifically, the cutter 14 moves up and down and is located between the two rolling wheels 11. Raising the two rolling wheels 11 provides support for the material when it is cut.

[0040] Working principle: When using the aluminum alloy door and window production bending machine, the forward and reverse threaded rods 3 are driven to rotate by rotating the hand handle 18. During the rotation of the forward and reverse threaded rods 3, the threaded blocks 4 connected by threads on both sides of the forward and reverse threaded rods 3 are driven to approach each other. The two threaded blocks 4 are driven to approach each other, and the two trapezoidal blocks 5 are driven to approach each other. The lifting plate 7 is pushed upward by the two trapezoidal blocks 5 approaching each other, and then the motor installed on the outside of the second rotating wheel 9 is started to drive the second rotating wheel 9 to rotate. The rotation of the second rotating wheel 9 drives the material to move horizontally to the bending head 15 position, and then bends. After the bending is completed, the first hydraulic rod 12 is started to drive the cutter 14 to move downward, so as to achieve the cutting of the bent material.
