Description

Technical Field

[0001] This application belongs to the technical field of aluminum profile processing equipment, and more specifically, relates to an aluminum profile multi-angle cutting device. Background Art

[0002] Aluminum profiles are components formed by processing aluminum alloy materials through processes such as rolling and extrusion, and are widely used in the industrial and construction industries. During use, it is often necessary to cut the end parts of two aluminum profiles into positive and negative angles respectively, so that the two aluminum profiles can be spliced at a certain angle. For example, after cutting two aluminum profiles into 45° positive and negative bevels, they are spliced into a right angle. In production, usually, after using a set of cutting equipment to cut the aluminum profile with a positive angle, the cutting angle of the cutting equipment is adjusted to cut the profile with a negative angle; or two sets of cutting equipment are used to cut the two aluminum profiles with positive and negative angles respectively. However, when adjusting the cutting angle in these two ways, it is difficult to ensure the accurate matching of positive and negative angles, which easily leads to a poor docking effect of the two cut aluminum profiles. Especially in the second way, the errors of the two sets of cutting equipment are different, which will exacerbate this situation. Summary of the Invention

[0036] Please refer to Figures 1 to 4 together, and now the aluminum profile multi-angle cutting device provided by the embodiment of the present application will be described. An aluminum profile multi-angle cutting device includes:

[0037] A positioning platform having an aluminum profile cutting position;

[0038] An angle adjustment mechanism disposed above the positioning platform, including a first swing arm, a first rack, a second swing arm, a second rack and a driving gear; the free end of the first swing arm is connected to the first rack, and the free end of the second swing arm is connected to the second rack; the first rack and the second rack are engaged with the driving gear, and the driving gear drives the first rack and the second rack to move towards or away from each other to drive the included angle between the first swing arm and the second swing arm to increase or decrease;

[0039] A first cutting machine, which is liftably connected to the first swing arm, is aligned with the aluminum profile cutting position, and swings with the first swing arm; and

[0040] The second cutting machine is connected to the second swing arm in a liftable manner, aligned with the cutting position of the aluminum profile, and swings with the second swing arm;

[0041] During the swinging of the first swing arm and the second swing arm driving the first cutting machine and the second cutting machine, the cutting plane of the first cutting machine and the cutting plane of the second cutting machine are symmetric about the cross-section of the aluminum profile cutting position.

[0042] Compared with the prior art, in the aluminum profile multi-angle cutting device of the embodiment of the present application, when the driving gear rotates, it can synchronously drive the two racks to move towards or away from each other, thereby driving the two swing arms to open or close, and can synchronously adjust the angles of the two cutting machines, so as to ensure that the positive and negative angles of the two cutting machines are the same, so that the two bevels cut from the aluminum alloy can be perfectly spliced.

[0043] In this embodiment, the positioning platform can be a flat plate, and a through groove is provided thereon as the aluminum profile cutting position, so that the aluminum profile can stably pass through the aluminum profile cutting position for the first cutting machine and the second cutting machine above to perform cutting.

[0044] The angle adjustment mechanism is installed above the positioning platform. The driving gear drives the first swing arm and the second swing arm to open or close through the first rack and the second rack, so that the first swing arm and the second swing arm drive the first cutting machine and the second cutting machine to change the angle. During the swinging of the first swing arm and the second swing arm driving the first cutting machine and the second cutting machine, the cutting plane of the first cutting machine and the cutting plane of the second cutting machine are symmetric about the cross-section of the aluminum profile cutting position, so that the positive and negative angles cut by the first cutting machine and the second cutting machine on the aluminum profile at the aluminum profile cutting position always remain the same, so that the two aluminum profiles can be perfectly butted. In specific implementation, the driving gear can be driven by a motor with a brake. After the motor brakes, the driving gear can be locked, so that the angles of the first cutting machine and the second cutting machine are fixed.

[0045] Both the first cutting machine and the second cutting machine can be circular saws, and the cutting planes of the first cutting machine and the second cutting machine are the planes where the saw blades are located.

[0046] During use, rotate the driving gear to rotate the cutting planes of the first cutting machine and the second cutting machine to the desired angles, such as +30° and -30°. Then, feed an aluminum profile into the aluminum profile cutting position. Use the first cutting machine to descend to cut a +30° bevel at the end of the aluminum alloy. Then, feed another aluminum profile into the aluminum profile cutting position. Use the second cutting machine to descend to cut a -30° bevel at the end of the aluminum alloy. It is also possible to feed an aluminum profile into the aluminum profile cutting position, align the middle of the aluminum profile with the first cutting machine and the second cutting machine above, and use the first cutting machine and the second cutting machine to descend alternately, so as to cut the aluminum profile into two sections from the middle and the bevel directions at both ends are opposite. During the cutting process, the position of the aluminum profile can be slightly adjusted to make the cut waste smaller.

The circles of the first rack and the second rack coincide with the rotation axes of the first swing arm and the second swing arm, so that when the driving gear drives the first rack and the second rack to move towards or away from each other, it can smoothly drive the first swing arm and the second swing arm to open or close.
