Technical Field

[0001] The present application belongs to the technical field of metal profile processing, and in particular relates to a sawing device for processing aluminum profiles. Background Art

[0002] When cutting aluminum profiles, the aluminum profiles need to be fixed. For the cutting of a small amount of aluminum profiles, manual fixation is sufficient, while for the cutting of a large number of aluminum profiles, fixation is required through tooling fixtures.

[0003] Existing devices, such as an aluminum profile sawing device shown in authorization publication number CN213672210U, include a platform with more than four rocker arms hinged on the platform. The above patent fixes the suspended aluminum profile through the rocker arm. In actual use, due to the different lengths to be cut, the rocker arm may be difficult to fix to the center when fixing the suspended aluminum profile. When contacting and fixing, due to the reduction of friction, the aluminum profile may no longer be horizontal under the action of gravity. At this time, after falling onto the collection rack, it deviates from the direction and cannot roll down normally for collection.

[0004] Therefore, we propose a sawing device for aluminum profile processing to solve the above problems. Utility Model Content

[0029] Working principle:

[0030] When the sawing device for processing aluminum profiles is used, the first motor 16 is turned on to drive the worm 15 to rotate, and the worm gear 14 is cooperated to drive the two lead screws 13 to rotate until the first slider 4 and the movable swing arm 5 move to the center of the aluminum profile to be cut, and then the bolt 17 and the second slider 11 are moved until the movable swing arm 5 is parallel to the fixed swing arm 2 on the same side, and the aluminum profile is placed on the platform 1 after tightening the butterfly nut 18, and the cylinder is turned on to drive the tensioning frame 9 to move backward, and the fixed swing arm 2 and the movable swing arm 5 rotate until the four clamping wheels 6 are close to the aluminum profile, that is, the fixing of the aluminum profile is completed, and the cutting assembly 8 is turned on at this time to cut. Component 8 moves downward to cut the aluminum profile. At this time, the cylinder is reversed and the second motor 30 is turned on. The fixed swing arm 2 and the movable swing arm 5 rotate, and the aluminum profile falls onto the collecting plate 20 through the through hole 7. After being blocked by the gear lever 24, the aluminum profile remains in a horizontal state. The second motor 30 drives the dial 27 and the cylindrical pin 29 to rotate. When the cylindrical pin 29 enters the radial groove, the convex locking arc 28 is just separated from the groove wheel 26, so that the cylindrical pin 29 drives the groove wheel 26 to rotate, and the rotating shaft 23 rotates intermittently. The aluminum profile falls onto the L-shaped plate 21 and is collected, that is, the entire use process of the sawing device for processing aluminum profiles is completed.
