Description

Technical Field

[0001] This utility model belongs to the field of heating furnace technology, and in particular relates to a rapid short bar heating furnace for producing aluminum profiles. Background Technology

[0002] Aluminum bars are a type of aluminum product. Before extruding aluminum bars into aluminum profiles, the short bars need to be slowly and evenly heated in an aluminum bar heating furnace.

[0003] In existing heating furnaces, the aluminum rods move slowly from the furnace inlet to the outlet during the heating process. During this process, the aluminum rods are relatively stationary, making it difficult to heat the contact surface between the aluminum rods and the conveying device. This can easily lead to uneven heating and affect the quality of the final product. Utility Model Content

[0004] This utility model addresses the problems in the prior art by proposing the following technical solution:

[0005] A rapid short bar heating furnace for producing aluminum profiles includes a furnace body and a support frame. A traveling beam is fixedly installed on the inner wall of the furnace body. A sliding sleeve and a drive mechanism are fixedly connected to the outer side of the support frame. The sliding sleeve is slidably engaged with the traveling beam. Rotary shafts are rotatably installed on both sides of the support frame. A turning roller is fixedly sleeved on the outer ring of the rotating shaft. The drive mechanism is connected to the end of the rotating shaft.

[0006] As a preferred embodiment of the above technical solution, the drive mechanism includes a worm gear, the worm gear being fixedly connected to a bearing bracket, the bearing bracket being fixed to the outside of the support frame, and a worm wheel being fixedly connected to one end of the rotating shaft, the worm wheel engaging with the worm gear for transmission.

[0007] As a preferred embodiment of the above technical solution, both of the rotating shafts are fixedly connected to sprockets, and the two sprockets are connected to a chain.

[0008] As a preferred embodiment of the above technical solution, a toothed groove is provided on one side of the traveling beam, and a gear is fixedly connected to one end of the worm gear, with the gear meshing with the toothed groove for transmission.

[0009] The beneficial effects of this utility model are as follows:

[0010] 1.

[0015] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0016] Example 1

[0017] like Figure 1 and Figure 2 As shown, a rapid short bar heating furnace for producing aluminum profiles includes a furnace body 10 and a support frame 20. A traveling beam 11 is fixedly installed on the inner wall of the furnace body 10. A sliding sleeve 21 and a drive mechanism are fixedly connected to the outer side of the support frame 20. The sliding sleeve 21 is slidably engaged with the traveling beam 11. Rotating shafts 22 are rotatably installed on both sides of the support frame 20. A turning roller 23 is fixedly sleeved on the outer ring of the rotating shaft 22. The drive mechanism is connected to the end of the rotating shaft 22.

[0018] Specifically, the furnace body 10 is equipped with a propulsion mechanism to control the movement of the sliding sleeve 21 on the traveling beam 11. During the heating process, the aluminum short rod is moved inside the furnace body 10 by the support frame 20. The drive mechanism can control the two rotating shafts 22 to drive the connected turning rollers 23 to rotate synchronously, causing the aluminum short rod placed inside to rotate, so that it can be heated evenly and improve product quality.

[0019] like Figure 1 and Figure 2 As shown, the drive mechanism includes a worm gear 30, a bearing bracket 31 fixedly connected to the worm gear 30, the bearing bracket 31 fixedly on the outside of the support frame 20, and a worm wheel 33 fixedly connected to one end of the rotating shaft 22, the worm wheel 33 meshing with the worm gear 30 for transmission.

[0020] Specifically, through the meshing transmission between the worm gear 33 and the worm 30, the worm 30 can drive the rotating shaft 22 to rotate when it rotates, which in turn drives the turning roller 23 to rotate.

[0021] like Figure 2 As shown, both shafts 22 are fixedly connected to sprockets 34, and the two sprockets 34 are connected to chains 35.

[0022] Specifically, through the cooperation of two sprockets 34 and chain 35, when one shaft 22 rotates, the other shaft 22 will rotate synchronously together. The pressure of the aluminum bar itself will generate friction with the two turning rollers 23, thereby driving the aluminum bar to rotate.

[0023] like Figure 2 As shown, a toothed groove 12 is provided on one side of the traveling beam 11, and a gear 32 is fixedly connected to one end of the worm gear 30. The gear 32 meshes with the toothed groove 12 for transmission.

[0024] Specifically, when the sliding sleeve 21 moves the support frame 20 toward the outlet of the furnace body 10, it drives the worm gear 30 to rotate on the bearing frame 31 through the meshing transmission of the gear 32 and the tooth groove 12.

[0025] Example 2

[0026] like Figure 1 and Figure 2 As shown, the rapid short bar heating furnace for producing aluminum profiles, compared to Embodiment 1, has a propulsion mechanism that includes two drive wheels and a drive chain. The two drive wheels are respectively installed on the inlet side and the outlet side of the furnace body 10 and are connected by the drive chain. They are kept parallel to the traveling beam 11. A buckle is fixedly connected to the outer side of the sliding sleeve 21 and engages with the drive chain. A motor is fixedly installed on the outer side of the furnace body 10, and a drive shaft is fixedly connected to the output end of the motor. The drive shaft passes through one side of the furnace body 10 and is fixedly connected to a drive wheel.

[0027] Specifically, the motor drives the transmission wheel connected to it to rotate through the transmission shaft. Through the cooperation of the two transmission wheels and the transmission chain, the sliding sleeve 21 can be moved on the traveling beam 11 to move the aluminum short rod placed on the turning roller 23 from the inlet to the outlet of the furnace body 10. After the aluminum short rod is removed, the sliding sleeve 21 is driven back to the inlet side of the furnace body 10.

[0028] Working principle: The motor in the propulsion mechanism drives the transmission wheel connected to it to rotate through the transmission shaft. Through the cooperation of the two transmission wheels and the transmission chain, the sliding sleeve 21 can move on the traveling beam 11. When the sliding sleeve 21 drives the support frame 20 to move towards the outlet of the furnace body 10, the meshing transmission of the gear 32 and the tooth groove 12 drives the worm 30 to rotate on the bearing frame 31. Through the meshing transmission of the worm wheel 33 and the worm 30, the worm 30 can drive the rotating shaft 22 to rotate, which in turn drives the turning roller 23 to rotate. Through the cooperation of the two sprockets 34 and the chain 35, when one rotating shaft 22 rotates, the other rotating shaft 22 will rotate synchronously. The pressure of the aluminum short bar itself will generate friction with the two turning rollers 23, which will drive the aluminum short bar to rotate, so that it can be heated evenly and improve product quality.

[0029] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
