Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Embodiment

[0026] Given by Figures 1-4 There is provided an aluminum bar heating furnace for the production of aluminum profiles, including a rack 1 and a heating furnace body 2;

[0027] In actual use, a furnace door is rotatably connected to the outside of the set rack 1, and the furnace door can be used for the user to place the aluminum bar inside the rack 1;

[0028] The heating furnace body 2 is assembled on the frame 1. A rotating assembly 3 is assembled inside the heating furnace body 2. A rotating disk 4 is assembled on the rotating assembly 3. A plurality of groups of clamping assemblies 5 are arranged around the center of the upper end face of the rotating disk 4.

[0029] Among them, the rotating assembly 3 includes a rotating shaft 33 that rotates inside the heating furnace body 2, and the rotating disk 4 is sleeved outside the rotating assembly 3.

[0030] A plurality of clamping notches 41 are formed on the outer circumferential surface of the rotating disk 4. A plurality of groups of clamping assemblies 5 are respectively arranged corresponding to one of the clamping notches 41 and are located above the clamping notches 41.

[0031] The clamping assembly 5 includes a limit seat 51 arranged on the rotating disk 4. A limit groove 52 is formed on the limit seat 51. A sliding clamp block 53 is slidably arranged in the limit groove 52. A positioning block 54 is detachably arranged on the side surface of the limit seat 51. The positioning block 54 and the sliding clamp block 53 are arranged parallel to each other in opposite directions.

[0032] In this embodiment, in actual use, the plurality of groups of clamping assemblies 5 arranged on the rotating disk 4 can be used to clamp and limit a plurality of aluminum bars. With the cooperation of the plurality of clamping notches 41 formed on the rotating disk 4, the user can position a plurality of aluminum bars on the rotating disk 4. When the user drives the rotating disk 4 to rotate inside the frame 1 by using the rotating assembly 3, the aluminum bars on the rotating disk 4 can be rotated and heated inside the frame 1. Compared with the heating method in the cited document, through the cooperation of the clamping assembly 5 and the rotating disk 4 set in this application, multiple aluminum bars can be clamped simultaneously, enabling the frame 1 to process more aluminum bars at one time, thereby improving the heating efficiency and reducing the heating time of a single aluminum bar.

[0033] Specifically, referring to Figures 3-4 , the clamping assembly 5 further includes a small lead screw 58 that rotates in the limit groove 52. The small lead screw 58 is meshed with the sliding clamp block 53.

[0034] In this embodiment, through the meshing setting between the small lead screw 58 and the sliding clamp block 53, in actual adjustment and use, the user controls the rotation of the small lead screw 58. At this time, under the linear limit of the limit groove 52, the sliding clamp block 53 meshed outside the small lead screw 58 can linearly move along the stroke range of the small lead screw 58.

[0035] Furthermore, the user places the aluminum bar to be heated in the clamping notch 41 and places the top end of the aluminum bar between the sliding clamp block 53 and the positioning block 54. At this time, rotate the small lead screw 58 to make the sliding clamp block 53 move towards the side of the positioning block 54. At this time, through the clamping of the positioning block 54 and the sliding clamp block 53, the clamping and limiting of the aluminum bar can be realized, and then the limiting process of the aluminum bar on the rotating disk 4 is completed.

[0036] Specifically, referring to Figure 4 , one end of the limit groove 52 penetrates through the limit seat 51 and extends to be connected with a rotating handle 59, and the outer part of the rotating handle 59 has a fillet treatment.

[0037] In this embodiment, in actual use, the rotating handle 59 provided can be used to drive the small lead screw 58 to rotate. By rotating the rotating handle 59, the user can make the small lead screw 58 rotate synchronously; at the same time, the fillet treatment on the outer part of the rotating handle 59 provided can improve the rotation comfort.

[0038] Specifically, referring to Figure 4 , clamping notches 55 are formed on the opposite side surfaces of the positioning block 54 and the sliding clamping block 53. The clamping notches 55 are triangular notches, and anti-slip threads 56 are formed on the inner wall surfaces of the clamping notches 55.

[0039] In this embodiment, when the sliding clamping block 53 and the positioning block 54 cooperate with each other and move towards each other, the clamping and limiting of the aluminum rod can be realized at this time. The clamping notches 55 formed on the positioning block 54 and the sliding clamping block 53 can further improve the clamping effect on the aluminum rod, and the anti-slip threads 56 formed on the wall surfaces of the clamping notches 55 can further increase the friction between the positioning block 54 and the sliding clamping block 53, thereby improving the clamping effect on the aluminum rod.

[0040] Specifically, referring to Figure 4 , a positioning bolt 57 is threadedly connected to the positioning block 54, and the other end of the positioning bolt 57 penetrates through the positioning block 54 and is threadedly connected with (51).

[0041] In this embodiment, considering that the clamping spacing requirements for aluminum rods of different sizes are different, in a preferred embodiment, the provided positioning block 54 can be detachably installed on the limit seat 51 by disassembling and installing the positioning bolt 57, so that the user can disassemble, install and replace the positioning blocks 54 of different sizes. At the same time, the detachable design makes the positioning block 54 easier and more portable during maintenance.

[0042] Specifically, referring to Figures 1-3 , a rotating motor 31 is assembled and arranged on the heating furnace body 2, a speed reducer 32 is assembled and arranged on the rotating motor 31, the output end of the rotating motor 31 is connected to the input end of the speed reducer 32, the output end of the speed reducer 32 penetrates through the heating furnace body 2 and is connected to the top end of the rotating shaft 33; a heavy-duty bearing 34 is assembled and arranged in the heating furnace body 2, and the bottom end of the rotating shaft 33 is rotatably connected to the heavy-duty bearing 34.

[0043] In this embodiment, through the connection between the rotating motor 31 and the speed reducer 32, the rotation drive of the rotating shaft 33 can be realized. In actual adjustment operations, the user connects the power supply to the rotating motor 31. Through the speed reduction process between the rotating motor 31 and the speed reducer 32, the rotating shaft 33 can rotate accordingly. At this time, the set rotating shaft 33 can drive the rotating disk 4 to rotate. At this time, several aluminum bars limited on the rotating disk 4 can be rotated and heated on the rack 1, realizing uniform heating of the aluminum bars.

[0044] In a preferred embodiment, the power connection method between the rotating motor 31 and the rotating shaft 33 is prior art, and the control circuit can be realized by simple programming by those skilled in the art, which belongs to the common knowledge in the field. Only its use is involved without modification, so the control method and circuit connection will not be described in detail.

[0045] The aluminum bar heating furnace for aluminum profile production of the present utility model:

[0046] First step: In actual use, when the user needs to heat the aluminum bar, the user first opens the furnace door of the rack 1, and then places the aluminum bars in the clamping notches 41 in sequence for clamping. When the aluminum bars are initially positioned in the clamping notches 41, at this time, the user adjusts the clamping assembly 5 so that the clamping assembly 5 can perform secondary limitation on the aluminum bars.

[0047] Second step: The user rotates the rotating handle 59 in the clamping assembly 5. At this time, through the connection between the rotating handle 59 and the small lead screw 58, the set clamping assembly 5 can rotate accordingly. Limited by the limiting groove 52, the sliding clamp block 53 engaged outside the small lead screw 58 can linearly slide in the limiting groove 52. The user rotates the rotating handle 59, so that the sliding clamp block 53 gradually moves towards the positioning block 54 until one end of the aluminum bar is clamped. At this time, through the two - time limitation of the clamping notch 41 and the clamping assembly 5, the aluminum bar can be stably limited on the rotating disk 4. The user adjusts several groups of clamping assemblies 5 in sequence to clamp the aluminum bars, and several aluminum bars can be circumferentially limited on the rotating disk 4.

[0048] Third step: After the aluminum bars are limited on the rotating disk 4, at this time, the user can close the furnace door of the rack 1 and turn on the heating mechanism in the rack 1 to heat the aluminum bars. Then the user connects the power supply to the rotating motor 31. Through the speed reduction process between the rotating motor 31 and the speed reducer 32, the rotating shaft 33 can rotate accordingly. At this time, the set rotating shaft 33 can drive the rotating disk 4 to rotate. At this time, several aluminum bars limited on the rotating disk 4 can be rotated and heated on the rack 1, realizing uniform heating of the aluminum bars.

[0049] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
