Description

Technical Field

[0001] This invention relates to the field of engineering construction technology, specifically a bending device and method for using an ultra-long aluminum-zinc coated roof panel. Background Technology

[0002] In the construction of metal roofing projects, due to the use of extra-long panels with angled bends, each extra-long panel needs to be bent at a specific angle without damaging the material to ensure a smooth and aesthetically pleasing corner. One common practice is to create a split roof at the ridge, using an additional layer there. However, this conventional ridge method is prone to deformation over time, leading to a higher risk of leaks. Another common practice is to use a roll bending machine to bend the extra-long panels into an arc shape. However, this method makes precise control of the bending angle difficult, resulting in material waste. Summary of the Invention

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0030] Furthermore, it should be understood that, for ease of description, the dimensions of the various components shown in the accompanying drawings are not drawn to actual scale; for example, the thickness or width of some layers may be exaggerated relative to other layers.

[0031] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined or described in one figure, it will not need to be discussed or described in detail in the description of the subsequent figures.

[0032] refer to Figures 1-3 This embodiment provides a bending device for an ultra-long galvanized aluminum roof panel, which includes a base 1 and a pressure block 2. Supports 7 are provided on both sides of the upper end of the base 1, and an electric hydraulic jack 8 is provided on the outward-facing side of the support 7. The support 7 and the electric hydraulic jack 8 are connected by a stacked force transmission component 4 and a movable adapter 5. The ends of the supports 7 on both sides are connected by a positioning baffle 6, with the pressure block 2 positioned on the upper end of the positioning baffle 6. It is worth noting that the pressure block 2 and the support 7 are also connected by a stacked force transmission component 4 and a movable adapter 5. That is, the end of the support 7 is connected to the end of the pressure block 2 and the end of the electric hydraulic jack 8 through the stacked force transmission component 4 and the movable adapter 5.

[0033] In this embodiment, an extrusion seat 3 is provided at the upper center of the base 1. The extrusion seat 3 is located on the inward side of the bracket 7 and at the lower end of the positioning baffle 6. The pressure block 2 and the extrusion seat 3 are on the same vertical line. It is worth noting that the extra-long galvanized aluminum-zinc coated roof panel to be bent is located at the upper end of the extrusion seat 3. Specifically, the lower end of the pressure block 2 is provided with an extrusion part, and the upper end of the extrusion seat 3 is provided with an opening. The outer diameter of the extrusion part is smaller than the inner diameter of the opening. That is, the extra-long galvanized aluminum-zinc coated roof panel to be bent at the upper end of the extrusion seat 3 is bent by the downward pressure of the pressure block 2.

[0034] Furthermore, a handle 202 is provided at the upper center of the pressure block 2, allowing the operator to quickly pick up the pressure block 2. At the same time, a weight reduction hole 201 is provided in the middle of the pressure block 2. The weight reduction hole 201 can significantly reduce the overall weight of the pressure block 2, making it easier for the operator to pick up and reducing the pressure it bears.

[0035] In this embodiment, the stacked force transmission component 4 includes a main force transmission component 401 and a secondary force transmission component 403. The main force transmission component 401 is located outside the secondary force transmission component 403, and the main force transmission component 401, the secondary force transmission component 403, and the support 7 are connected via a movable adapter 5. Specifically, the movable adapter 5 has a first through hole in its center, the diameter of which is the same as the outer diameter of the rod of the secondary force transmission component 403. That is, the main force transmission component 401 is located on one side of the movable adapter 5 and is positioned at the upper end of the electric hydraulic jack 8, while the secondary force transmission component 403 is located at the upper side of the pressure block 2. In other words, the secondary force transmission component 403 can rotate left and right; during use, it can rotate to the upper side of the pressure block 2, and when not in use, it can rotate into the main force transmission component 401. It is worth noting that a rubber pad 402 is provided inside the secondary force transmission component 403. By setting the rubber pad 402, the friction between the pressure block 2 and the secondary force transmission component 403 can be reduced during the pressing of the pressure block 2, thereby reducing the wear of the pressure block 2.

[0036] In this embodiment, the support 7 includes a movable frame 701 and a fixed frame 702. The movable frame 701 is disposed inside the fixed frame 702, and both the inward-facing side of the movable frame 701 and the inward-facing side of the fixed frame 702 have second through holes. It is worth noting that the diameter of the second through holes is not less than the outer diameter of the positioning baffle 6. The movable frame 701 is provided with a sliding groove, and a scale 704 is provided on the outside of the movable frame 701. The ends of the movable frame 701 and the positioning baffle 6 are fixedly connected by a fastener 703. That is, the descending distance of the positioning baffle 6 is determined by the scale 704, allowing for better control of the bending angle of the extra-long aluminized zinc roofing panel during the descent of the pressure block 2, thereby achieving bending accuracy.

[0037] This embodiment also provides a method for using a bending device for extra-long aluminized zinc roof panels, which specifically includes the following steps:

[0038] Step S1: Based on the formula for calculating the side length of a triangle and the bending angle of the extra-long galvanized steel roof panel, the vertical distance corresponding to the bending angle can be determined. According to this vertical distance, during the descent of the positioning baffle 6, lower it to the position on the scale 704 that corresponds to the vertical distance of the bending angle. After the positioning baffle 6 reaches the appropriate position, it is fixedly connected to the movable frame 701 using the fastener 703.

[0039] Step S2: Place the extra-long galvanized aluminum-zinc coated roof panel to be bent on the upper end of the extrusion seat 3, while simultaneously lowering the pressure block 2 to the side of the movable adapter 5, and rotating the auxiliary force transmission component 403 from inside the main force transmission component 401 to the upper end of the pressure block 2. It is worth noting that, to protect the surface of the extra-long galvanized aluminum-zinc coated roof panel to be bent, a protective material can be laid on the surface of the panel to avoid damaging the protective layer.

[0040] Step S3: Activate the electric hydraulic jack 8. Under the action of the electric hydraulic jack 8, it applies force to the main force transmission component 401, which transmits the force to the auxiliary force transmission component 403. The auxiliary force transmission component 403 then transmits the force to the pressure block 2, causing the pressure block 2 to gradually press down. Once the pressure block 2 is pressed down to the positioning baffle 6, the electric hydraulic jack 8 can be turned off. Then, rotate the auxiliary force transmission component 403 into the interior of the main force transmission component 401 and move the pressure block 2 and the positioning baffle 6 upwards to obtain the bent extra-long galvanized aluminum roof panel.

[0041] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
