Description

Technical Field

[0001] The utility model belongs to the technical field of anti-bending of aluminum profiles, and particularly relates to an anti-bending device for aluminum profile extrusion. Background Technique

[0002] Aluminum alloy extrusion molding is to use an extruder to apply high pressure to an aluminum alloy blank in a mold, so that it is extruded through a die hole and forms the required cross-sectional shape, commonly known as "pulling aluminum" and "aluminum extrusion". Its technological characteristics are to heat the aluminum rod to about 480 degrees through a heating furnace, and then heat the mold to 480 degrees at the same time. Then, the heated aluminum rod is extruded and formed through the pre-installed mold by mechanical pressure.

[0003] After extrusion molding, the temperature of the aluminum alloy profile is relatively high. When dissipating heat, the surface of the aluminum profile is usually cooled by air cooling, so as to cool the aluminum profile. However, in this way, the heat dissipation speed of the part directly in contact with the cold air is relatively fast, while the heat dissipation speed of other parts is relatively slow, which is likely to cause uneven heat dissipation and thus easily cause the aluminum profile to bend. Content of the Utility Model

[0004] In order to solve the above problems, the purpose of the utility model is to provide an anti-bending device for aluminum profile extrusion.

[0005] To achieve the above purpose, the utility model provides an anti-bending device for aluminum profile extrusion, which includes a box body. Both sides of the box body are open. Horizontal plates are fixedly connected to both sides inside the box body. Vertical plates are fixedly connected to the upper surfaces of the horizontal plates. The vertical plates on the two horizontal plates are symmetrically arranged. A rotating wheel is rotatably arranged between the horizontal plates. The rotating wheels are arranged in an array, and a multi-directional air-cooling heat dissipation component is arranged between adjacent rotating wheels.

[0006] In one example, the multi-directional air-cooling heat dissipation component includes four fixed pipes. The fixed pipes are fixedly connected to the box body. The fixed pipes penetrate the box body. Fixed rings are fixedly connected to the four fixed pipes. The fixed pipes pass through the fixed rings. Nozzles are fixedly connected to one ends of the four fixed pipes. The nozzles face the center position of the fixed ring. The four nozzles are arranged in an annular array. The other ends of the fixed pipes are communicated with hoses, and the other ends of the hoses are connected to a blower.

[0007] In one example, two mounting frames are arranged inside the box body. A plurality of first extrusion wheels are rotatably connected to the mounting frames. Support plates are fixedly connected to the other sides of the two mounting frames. Cross bars are fixedly connected to one sides of the support plates. An electric push rod is fixedly connected to the outer side wall of the box body. The telescopic rod of the electric push rod penetrates the box body and is fixedly connected to one of the cross bars, and the other cross bar is fixed to the inner wall of the box body.

[0008] In one example, the height of the mounting bracket is higher than that of the rotating wheel. The two mounting brackets are located on both sides of the vertical center line of the rotating wheel. The first pressing wheel corresponds to the rotating wheel in position, and the number of the rotating wheel is the same as that of the first pressing wheel.

[0009] In one example, two mounting plates are fixedly connected to the upper bottom surface inside the box body, and a plurality of second pressing wheels are rotatably connected between the two mounting plates. The number of the second pressing wheels is the same as that of the first pressing wheels, and the positions correspond to those of the first pressing wheels and the rotating wheel.

[0010] In one example, the height of the second pressing wheel is higher than that of the mounting bracket, and the length of the second pressing wheel is greater than that of the first pressing wheel.

[0011] In one example, four hydraulic lifting rods are fixedly connected to the lower surface of the box body, and the lower ends of the four hydraulic lifting rods are fixedly connected to the bottom plate.

[0012] The aluminum profile extrusion anti-bending device proposed by the present utility model can bring the following beneficial effects:

[0013] First, by setting the fixing rings, when the aluminum profile passes through each fixing ring, the blower is turned on. The wind passes through the hose and the fixed pipe and is sprayed out through the nozzle, impacting the aluminum profile in a fan shape, blowing and dissipating heat on the aluminum profile from multiple directions, so that all sides of the aluminum profile are blown, making the heat dissipation effect of each position of the aluminum profile the same, avoiding different heat dissipation effects at different positions of the aluminum profile, resulting in different temperatures at different positions of the aluminum profile, and thus causing bending.

[0014] Second, by setting the rotating wheel, the first pressing wheel and the second pressing wheel, the electric push rod pushes another mounting bracket to move, so that the first pressing wheel on this mounting bracket presses on the other side of the aluminum profile for extrusion. When the aluminum profile passes through the box body, it is restricted by the rotating wheel and the second pressing wheel on the upper and lower sides, avoiding the deformation and bending of the aluminum profile.

Specific implementation mode

[0022] In order to more clearly explain the overall concept of the present utility model, the following will be described in detail by way of example in conjunction with the drawings in the specification.

[0023] As Figures 1 to 4 shown, an embodiment of the present utility model provides a device for preventing bending during aluminum profile extrusion, including a box body 1. Both sides of the box body 1 are open. On both sides inside the box body 1, horizontal plates 2 are fixedly connected. On the upper surfaces of the horizontal plates 2, vertical plates 3 are fixedly connected. The vertical plates 3 on the two horizontal plates 2 are symmetrically arranged. A rotating wheel 4 is rotatably arranged between the horizontal plates 2. The rotating wheels 4 are arranged in an array. A multi-directional air-cooled heat dissipation component 5 is provided between adjacent rotating wheels 4. During use, the box body 1 is aligned with the aluminum profile extrusion equipment. After the aluminum profile is extruded and formed, it enters the box body 1. The lower surface of the aluminum profile directly contacts the rotating wheels 4 inside the box body 1. The rotating wheels 4 are driven by a motor. All the rotating wheels 4 drive the aluminum profile to pass through the box body 1 through friction. During this process, the multi-directional air-cooled heat dissipation component 5 between the rotating wheels 4 blows air to dissipate heat from multiple directions to the aluminum profile, so that all sides of the aluminum profile are blown by air, and the heat dissipation effect at each position of the aluminum profile is the same, avoiding different heat dissipation effects at different positions of the aluminum profile, resulting in different temperatures at different positions of the aluminum profile, and thus causing bending.

[0024] Specifically, the multi-directional air-cooling heat dissipation assembly 5 includes four fixed pipes 51. The fixed pipes 51 are fixedly connected to the box body 1. The fixed pipes 51 penetrate through the box body 1. Fixed rings 52 are fixedly connected to the four fixed pipes 51. The fixed pipes 51 pass through the fixed rings 52. One end of each of the four fixed pipes 51 is fixedly connected to a nozzle 53. The nozzle 53 faces the center position of the fixed ring 52. The four nozzles 53 are arranged in an annular array. The other end of the fixed pipe 51 is communicated with a hose. The other end of the hose is connected to a blower. The center position of the fixed ring 52 is located above the rotating wheel 4. When the aluminum profile passes through each fixed ring 52, the blower is turned on. The wind passes through the hose and the fixed pipe 51 and is ejected through the nozzle 53, impacting on the aluminum profile in a fan shape, so that the wind forces received by all sides of the aluminum profile are the same, facilitating the control of the heat dissipation effect of each position of the aluminum profile.

[0025] Specifically, two mounting brackets 6 are provided in the box body 1. A plurality of first pressing wheels 7 are rotatably connected to the mounting brackets 6. On the other side of each of the two mounting brackets 6, a support plate 8 is fixedly connected. A cross bar 9 is fixedly connected to one side of each support plate 8. An electric push rod 10 is fixedly connected to the outer side wall of the box body 1. The telescopic rod of the electric push rod 10 penetrates through the box body 1 and is fixedly connected to one of the cross bars 9. The other cross bar 9 is fixed to the inner wall of the box body 1. One of the two mounting brackets 6 is fixedly connected to the electric push rod 10 and can move horizontally, while the other mounting bracket 6 is fixed to the box body 1 and cannot move. After the aluminum profile enters the box body 1 and is located between the two mounting brackets 6, the position of the box body 1 is adjusted so that the side surface of the aluminum profile contacts the first pressing wheels 7 on the non-movable mounting bracket 6. The electric push rod 10 pushes the other mounting bracket 6 to move, so that the first pressing wheels 7 on this mounting bracket 6 press on the other side of the aluminum profile for extrusion. While the aluminum profile passes through the box body 1, both sides are squeezed. During the cooling and shaping process, through horizontal extrusion, the aluminum profile is prevented from deforming and bending in the horizontal direction.

[0026] Specifically, the height of the mounting bracket 6 is higher than that of the rotating wheel 4. The two mounting brackets 6 are located on both sides of the vertical center line of the rotating wheel 4. The first pressing wheels 7 correspond to the position of the rotating wheel 4. The number of the rotating wheel 4 and the first pressing wheels 7 is the same. The position of the first pressing wheels 7 is above the rotating wheel 4, which will not affect the rotation of each other. At the same time, the first pressing wheels 7 are located on one side of the rotating wheel 4 and between the fixed rings 52. The first pressing wheels 7 will not block the nozzles 53 on the fixed rings 52, resulting in the wind not being fully ejected onto the aluminum profile and affecting heat dissipation.

[0027] Specifically, two mounting plates 11 are fixedly connected to the upper bottom surface inside the box body 1. A plurality of second pressing wheels 12 are rotatably connected between the two mounting plates 11. The number of the second pressing wheels 12 is the same as that of the first pressing wheels 7, and the positions correspond to those of the first pressing wheels 7 and the rotating wheels 4. When the aluminum profile enters the box body 1, its upper surface contacts the second pressing wheels 12, and its lower surface contacts the rotating wheels 4. It is squeezed and restricted by the second pressing wheels 12 and the rotating wheels 4 in the vertical direction, preventing the aluminum profile from bending and warping in the vertical direction.

[0028] Specifically, the height of the second pressing wheels 12 is higher than that of the mounting brackets 6, and the length of the second pressing wheels 12 is greater than that of the first pressing wheels 7. The second pressing wheels 12 also do not avoid the fixed rings 52 and will not block the nozzles 53. The two mounting brackets 6 are always located between the second pressing wheels 12 and the rotating wheels 4. Therefore, when the aluminum profile enters the box body 1, its lower part, upper part, and one side surface respectively contact the rotating wheels 4, the second pressing wheels 12, and the first pressing wheels 7 on the immovable mounting brackets 6.

[0029] Specifically, four hydraulic lifting rods 13 are fixedly connected to the lower surface of the box body 1. The lower ends of the four hydraulic lifting rods 13 are fixedly connected to a bottom plate 14. The hydraulic lifting rods 13 push the box body 1 to rise, adjusting the height of the box body 1, so that the aluminum profile enters the box body 1 after being extruded from the extrusion equipment, facilitating the extrusion and cooling of the aluminum profile.

[0030] Working principle: The hydraulic lifting rods 13 push the box body 1 to rise, adjusting the height of the box body 1. The aluminum profile enters the box body 1 after being extruded from the extrusion equipment. Its lower part, upper part, and one side surface respectively contact the rotating wheels 4 and the second pressing wheels 12. The electric push rod 10 pushes another mounting bracket 6 to move, so that the first pressing wheel 7 on this mounting bracket 6 presses on the other side of the aluminum profile for extrusion, enabling all sides of the aluminum profile to be squeezed. The rotating wheels 4 are driven by a motor, and all the rotating wheels 4 drive the aluminum profile to pass through the box body 1 through friction. When the aluminum profile passes through each fixed ring 52, the blower is turned on, and the wind passes through the hose and the fixed pipe 51 and is sprayed out through the nozzles 53, impacting the aluminum profile in a fan shape, so that the wind received by all sides of the aluminum profile is the same for heat dissipation.

Each embodiment focuses on the differences from other embodiments. In particular, for the system embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can refer to the partial description of the method embodiment.
