[0035] Embodiment 1

[0036] As Figures 1 to 2 shown, this embodiment proposes:

[0037] A bending processing machine for profiles of broken bridge aluminum doors and windows, comprising:

[0038] A frame 1, a processing table 2 is fixed on the top wall of the bottom plate of the frame 1, a rectangular bending groove 3 is opened on the top wall of the processing table 2, and sliding grooves 4 are symmetrically opened on both sides of the rectangular bending groove 3;

[0039] A trapezoidal block 5 is slidably mounted in the slide groove 4, and an adjusting component 6 for driving the trapezoidal block 5 to move is installed inside the bottom end of the processing table 2;

[0040] A hydraulic cylinder 7 is fixed on the top plate of the frame 1, and a movable end at the bottom of the hydraulic cylinder 7 slides through the top plate of the frame 1 and is fixed with a mounting frame 8;

[0041] The bending assembly 9 is rotatably mounted between the inner walls of the mounting frame 8 , and the outer wall of the mounting frame 8 is provided with a positioning assembly 10 for positioning the bending assembly 9 .

[0042] In this embodiment, the rectangular bending groove 3 arranged on the processing table 2 can cooperate with the bending component 9 to process a U-shaped thermally broken aluminum door and window profile. The position of the trapezoidal block 5 is adjusted by the adjusting component 6, so that the bending component 9 can be cooperated to process V-shaped and trapezoidal thermally broken aluminum door and window profiles. It has a wide range of applications. The hydraulic cylinder 7 is used to control the downward movement of the bending component 9 to cooperate with the processing table 2 to bend the plate-like thermally broken aluminum door and window profile. The positioning component 10 is used to fix the position of the bending component 9 to ensure that the bending part of the bending component 9 can bend the thermally broken aluminum door and window profile vertically downward.

[0043] Example 2

[0044] like Figures 3 to 5 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes:

[0045] A mounting groove 11 is provided inside the processing table 2 , and the adjustment assembly 6 is installed in the mounting groove 11 .

[0046] The adjustment assembly 6 includes a bidirectional screw 61, which is rotatably mounted in the mounting groove 11, and screw blocks 62 are screwed at both ends of the bidirectional screw 61;

[0047] The screw block 62 is slidably installed in the installation groove 11, and the top of the screw block 62 is fixedly connected to the bottom wall of the corresponding trapezoidal block 5;

[0048] One end of the bidirectional screw 61 passes through the side wall of the processing table 2 through a bearing and is fixed with a hand wheel 63 .

[0049] A through slot 12 is defined between the bottom wall of the slide slot 4 and the top wall of the mounting slot 11 , and the top of the screw block 62 is slidably mounted in the through slot 12 .

[0050] In this embodiment, the provided adjusting component 6 can adjust the position of the trapezoidal block 5, and can cooperate with the bending component 9 to process V-shaped and trapezoidal broken bridge aluminum door and window profiles, with a wide range of applications. By rotating the handwheel 63 to drive the rotation of the bidirectional screw 61, the trapezoidal blocks 5 are driven to approach each other during the rotation of the bidirectional screw 61. When the bevel edge of the trapezoidal block 5 coincides with the top edge of the rectangular bending groove 3, at this time, it can cooperate with the bending component 9 to process trapezoidal broken bridge aluminum door and window profiles. When the bottom edges of the two trapezoidal blocks 5 are in contact, at this time, it can cooperate with the bending component 9 to process V-shaped broken bridge aluminum door and window profiles.

[0051] The bending component 9 includes a mounting block 91, and the mounting block 91 is rotatably installed between the inner walls of the mounting frame 8. Symmetrically fixed on the side wall of the mounting block 91 are T-shaped connecting blocks 92, and a bending head 93 is detachably fixed to one end of each T-shaped connecting block 92 away from the mounting block 91.

[0052] The bending head 93 is fixedly connected to the T-shaped connecting block 92 by bolts.

[0053] The shapes of the bending heads 93 are respectively rectangular, triangular, and trapezoidal.

[0054] The positioning component 10 includes a housing 101, and the housing 101 is fixed to the bottom of the outer wall of the mounting frame 8. A pin shaft 102 is slidably installed in the housing 101;

[0055] A limiting plate 103 is fixed on the shaft body of the pin shaft 102, and a spring 104 is sleeved on the outer surface of the pin shaft 102;

[0056] The spring 104 is fixed between the limiting plate 103 and the inner wall of the housing 101;

[0057] One end of the pin shaft 102 slidably penetrates through the housing 101 and is fixed with a pull plate 105, and the other end of the pin shaft 102 slidably penetrates through the side wall of the mounting frame 8.

[0058] A positioning hole 13 matching the pin shaft 102 is formed in the side wall of the T-shaped connecting block 92.

[0059] In this embodiment, the bending assembly 9 is provided with bending heads 93 in the shapes of rectangle, triangle and trapezoid, so that it can cooperate with the processing table 2 to process U-shaped, V-shaped and trapezoid-shaped broken bridge aluminum door and window profiles. At the same time, the bending heads 93 and the T-shaped connecting blocks 92 are fixed by bolts, so that the corresponding bending heads 93 can be replaced when damaged. The positioning assembly 10 provided can make the corresponding bending heads 93 vertically downward. When it is necessary to switch the bending heads 93, pull the pull plate 105 outward. The pull plate 105 drives the pin shaft 102 to move outward. At this time, the spring 104 is compressed by force until the pin shaft 102 disengages from the current positioning hole 13. At this time, rotate the mounting block 91 to make the corresponding bending head 93 vertically downward, and release the pull plate 105. The pull plate 105 resets under the action of the spring 104, and at the same time the pin shaft 102 is snapped into the positioning hole 13 to complete the switching of the bending head 93.

[0060] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
