A discharge port is arranged at the right end of the aluminum scrap drying oven 1, and a cutting assembly 2 is arranged at the discharge port. An aluminum door frame forming box 3 is connected to the rear side of the cutting assembly 2. The right end of the aluminum door frame forming box 3 is a discharge port, and a traction platform 4 is connected to the discharge port. It is explained here that the aluminum scrap drying oven 1 is an existing device, which is used to bake scrap aluminum materials of different shapes to obtain aluminum rods; the aluminum door frame forming box 3 is an existing device, which is used to form aluminum rods to obtain door frame-shaped aluminum materials; the traction platform 4 is an existing conveying device, and since they are all existing technologies, they will not be described in detail here. A slide rail 41 with the same elongation direction as its extension direction is arranged on the rear side of the traction platform 4, and two traction members 42 are slidably arranged on the slide rail 41.

[0020] All the aluminum scraps are put into the aluminum scrap drying oven 1 for baking and hot forming to obtain aluminum rods. The aluminum scrap drying oven 1 feeds the aluminum rods into the cutting assembly 2, and the cutting assembly 2 cuts aluminum rods of suitable sizes. The cut aluminum rods fall into the aluminum door frame forming box 3 to form door frame-shaped aluminum materials, which are then fed to the traction platform 4. Two traction members 42 grasp the two ends of the door frame-shaped aluminum material and apply forces in opposite directions, thereby eliminating the stress in the door frame-shaped aluminum material.

[0021] The cutting assembly 2 includes a frame 21. A cutting portion 22 with a hollow interior is provided on the upper side of the frame 2. The cutting portion 22 is provided with a through opening 23 that matches the position and shape of the discharge port of the aluminum waste drying oven 1, and the aluminum rod passes through the through opening 23. A discharge plate 24 that is connected to the aluminum door frame forming box 3 is provided on the lower side of the frame 24, and the discharge plate 24 is inclined. The discharge plate 24 is located on the side of the cutting portion 22 away from the aluminum waste drying oven 1. A U-shaped strip 27 and a screw 28 are rotatably provided on the side of the cutting portion 22 away from the aluminum waste drying oven 1. The contact assembly 5 is slidably mounted on the U-shaped strip 27, and the screw 28 is threadedly rotatably provided through the contact assembly 5. An adjusting disk 29 is provided at the end of the screw 28. A roller 52 is rotatably provided at one end of the contact assembly 5 close to the cutting portion 22. A cutting knife 25 for cutting aluminum rods is slidably provided up and down in the cutting portion 22. A cylinder 26 for driving the cutting knife 25 is provided on the upper side of the cutting part 22. The contact assembly 5 is connected to the cylinder 26 by signal. When the aluminum rod abuts against the contact assembly 5, the contact assembly 5 sends a signal to the cylinder 26, and the cylinder 26 starts to drive the cutting knife 25 to cut the aluminum rod. The cut aluminum rod falls into the discharge plate 24 and enters the aluminum door frame forming box 3 under the action of gravity.

[0022] As a further improvement of the present invention, it can be further extended according to the above cases to provide a variety of new embodiments.

[0023] As a second embodiment of the present invention, based on embodiment 1, refer to Figure 4-Figure 6 The side wall of the aluminum scrap drying oven 1 is slidably provided with two baffles 11 that cooperate with each other to seal the discharge port of the aluminum scrap drying oven 1. The two baffles 11 are respectively located on the upper and lower sides of the discharge port of the aluminum scrap drying oven 1. The side of the baffle 11 close to the discharge port of the aluminum scrap drying oven 1 is an inclined surface. The side wall of the aluminum scrap drying oven 1 is provided with corresponding base blocks 12 that match the number and position of the baffles 11 one by one. A first return spring 13 is provided between the base block 12 and the baffle 11, and the two ends are connected to the two. The first return spring 13 is in a natural state, and the two baffles 11 seal the discharge port of the aluminum scrap drying oven 1.

[0024] After the aluminum scrap drying oven 1 heat processes the aluminum scrap to obtain aluminum rods, the aluminum rods are sent out of the aluminum scrap drying oven 1, and the aluminum rods push open the two baffles 11. When the aluminum rods are completely discharged, the two baffles seal the discharge port of the aluminum scrap drying oven 1 under the restoring force of the first return spring 13 to prevent the heat in the aluminum scrap drying oven 1 from being lost.

[0025] The contact assembly 5 includes a contact housing 51 slidably disposed on the U-shaped strip 27. The contact housing 51 is hollow inside and open on the right side. A first oil cylinder 53 is disposed in the contact housing 51, a first partition 54 is slidably disposed in the first oil cylinder 53, and a first output rod 55 is disposed on the first partition 54.

A lever 65 corresponding to the number and position of the second oil cylinder 61 is hingedly provided in the driving housing 6. A rolling ball 66 slidably connected to the cutting knife 25 is provided at the lower end of the lever 65, and the upper end is connected to the second output rod 63 in the matching second oil cylinder 61. The distance between the second oil cylinder 61 and the hinge point 67 is greater than the distance between the rolling ball 66 and the hinge point 67. It is to be noted that a sleeve is slidably provided on the lever 65 , and the sleeve is hingedly connected to the second output rod 63 .

[0027] The rodless chamber in the first oil cylinder 53 is connected to the rod chamber in the second oil cylinder 61 through a liquid pipe. The rodless chamber in the first oil cylinder 53 and the rod chamber in the second oil cylinder 61 are filled with liquid oil in a normal state. When the aluminum rod contacts the roller 52, the aluminum rod continues to move forward, causing the roller 52 to move, and the second return spring 56 is stretched, thereby reducing the area of ​​the rodless chamber in the first oil cylinder 53, and the liquid oil in the rodless chamber in the first oil cylinder 53 is squeezed and enters the rod chamber in the second oil cylinder 61, thereby driving the second output rod 63 to move, and the third return spring 64 is compressed, thereby causing the lever 65 to rotate, pushing the cutting knife 25 down to cut the aluminum rod. After the aluminum rod is cut and falls into the discharge plate 24, the roller 52 is no longer squeezed, and under the action of the restoring force of the second return spring 56 and the third return spring 64, the positions of the roller 52 and the cutting knife 25 are restored.
