[0039] See also Figures 1 to 4 As shown, a synchronous bending device for aluminum alloy bars is characterized by comprising:

[0040] A base 1, on which a fixing rod 2 and a driving assembly 3 are fixed respectively, on which a rack 1 and a slide rail are fixed, and on the top of which a top platform 5 is fixed;

[0041] The bending assembly 4 is slidably disposed on the slide rail and meshes with the rack. The bending assembly 4 specifically includes:

[0042] A housing 41 is slidably disposed on the slide rail and fixed to the driving assembly 3;

[0043] A gear 1 42 is rotatably disposed on the housing 41 and meshes with the rack 1;

[0044] Gear 2 43, arranged in two pieces, rotatably supported on the housing 41, and meshing with gear 1 42;

[0045] A second rack 45 is slidably disposed in the housing 41 and meshes with the second gear 43;

[0046] Gear three 48, rotatably disposed in the housing 41 and meshing with the rack two 45;

[0047] A rack 3 46 is slidably disposed in the housing 41 and meshes with the gear 3 48; and

[0048] The bearing mechanism 47 is slidably disposed on the housing 41 and fixed to the rack three 46 .

[0049] like Figure 1-Figure 2 As shown, the utility model also includes: the gear 1 42 is a double-wheel coaxial arrangement, the inner gear meshes with the rack 1, and the outer gear meshes with the gear 2 43; the gear 2 43 is a double-wheel coaxial arrangement, the inner gear meshes with the outer gear of the gear 1 42, and the outer gear meshes with the rack 2 45; the gear diameters d of the left and right outer gears are different, and the diameter d of the left outer gear is 1 Smaller than the right external gear direct d 2 ; A torsion spring is fixed on the rotating shaft of the gear three 48.

[0050] When it is necessary to bend the aluminum alloy rod, first place the aluminum alloy rod on the supporting mechanism 47, then start the driving assembly 3, and under the action of the driving assembly 3, the shell 41 slides up along its slide rail. During the sliding process of the shell 41, the meshing action of the rack 1 and the gear 1 42 will cause the gear 1 42 to rotate. However, since the two wheels of the gear 1 42 are coaxially arranged and the two wheels are directly connected by a ratchet, the gear 1 42 will not be able to drive the gear 2 43 during the sliding process of the shell 41, so that the aluminum alloy rod completes the bending operation under the action of the supporting mechanism 47 and the top platform 5.

[0051] After the aluminum alloy rod bending operation is completed, the driving assembly 3 will make the shell 41 slide down along the slide rail. At this time, the rotation of gear 1 42 under the action of rack 1 will synchronously drive gear 2 43 to rotate, that is, during the rotation process of gear 2 43, the outer gear will drive rack 2 45 to slide, and the sliding of rack 2 45 will drive gear 3 48 to rotate, that is, under the rotation of gear 3 48, rack 3 46 will move up, so that the bearing mechanism 47 slides up in the shell 41, so that the aluminum alloy rod after bending is separated from the limitation of the shell 41, so as to facilitate the taking and placing of the bent aluminum alloy rod.

[0052] The left and right external gears have a diameter of d 1 Smaller than the diameter d of the right external gear 2 That is, under the condition that the gear three 48 rotates the same number of times, the bent aluminum alloy rod will appear in an inclined state with the left side lower and the right side higher, so that the aluminum alloy rod can slide freely under the gravity, thereby improving the separation effect of the bent aluminum alloy rod.

[0053] The torsion spring is set so that after the aluminum alloy rod slides down, the housing 41 reaches the lowest limit position under the action of the drive assembly 3, that is, the housing 41 stops descending so that the outer wheel of gear 1 42 is freed from the restriction of rack 1 under the action of the ratchet, and the bearing mechanism 47 is restored to its initial state under the action of the torsion spring.

[0054] like Figure 3 As shown, the utility model also includes: the carrying mechanism 47 includes:

[0055] A bearing rod 471 is slidably disposed on the housing 41 and has fixing posts 472 rotatably disposed at both ends; and

[0056] The support platform 473 is fixed on the rack three 46 and connected to the fixing column 472 .

[0057] like Figure 4 As shown, the utility model also includes: the driving component 3 includes:

[0058] A slide 31 is fixed on the base 1;

[0059] A telescopic rod 32 is fixed on the slide 31 and is rotatably connected to one end of a connecting rod 33 at an output end;

[0060] A triangular plate 34 rotatably connected to the other end of the connecting rod 33;

[0061] A limiting rod 35, one end of which is rotatably disposed on the triangular plate 34, and the other end of which is rotatably disposed on the housing 41; and

[0062] The second limiting rod has one end rotatably disposed on the triangular plate 34 and the other end rotatably disposed on the base 1;

[0063] The slide table 31 is provided with an adjuster, and the telescopic rod 32 is fixed on the adjuster.

[0064] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
