A heating furnace

Abstract

This invention provides a heating furnace, including a transport device, a tilting device, and a positioning device. The tilting device and the positioning device are respectively connected to the transport device. The transport device includes a conveyor belt and a frame. The conveyor belt is drivenly connected to the frame. The positioning device is connected to the conveyor belt. The tilting device is used to tilt the aluminum rods on the positioning device. By incorporating the tilting device and the positioning device, and with the positioning device connected to the conveyor belt, the heating furnace achieves more uniform heating of the aluminum rods on the positioning device. This prevents the side of the aluminum rod in contact with the conveyor belt from being unable to undergo preheating. Specifically, because the temperature on the side of the aluminum rod in contact with the conveyor belt is conducted to the conveyor belt, the temperature on that side of the aluminum rod is lower. Therefore, tilting the aluminum rod can prevent melting and solve the problem of large temperature differences between the core and surface of the aluminum rod.

Description

Technical Field

[0001] This invention relates to the field of aluminum production equipment technology, and more specifically, to a heating furnace. Background Technology

[0002] Before producing various aluminum products using aluminum rod extrusion molding, the aluminum rods need to be heated first. An aluminum rod single-rod furnace (the aluminum rod single-rod furnace mentioned in this article refers to a tunnel-type aluminum rod single-rod furnace) is a device used to heat aluminum rods. Generally, an aluminum rod single-rod furnace has a heating chamber inside the furnace body. Multiple burners are arranged along the length of the heating chamber. A preheating chamber is set at the front end of the heating chamber, and an exhaust device is set at the preheating chamber. When the aluminum rod is in the heating chamber, the gas and air are mixed and sprayed out from the burners to burn and heat the aluminum rod. The generated flue gas flows forward along the heating chamber and enters the preheating chamber to preheat the aluminum rod in front. Finally, the flue gas is discharged by the exhaust device.

[0003] Since the temperature of aluminum rods is generally required not to exceed 530℃, while the flame temperature is about 1300℃ to 1400℃ and the generated flue gas is about 1000℃, when the flue gas flows along the heating chamber, it will reheat the aluminum rods in the front zone, making accurate temperature control impossible and even posing a risk of melting the rods. To avoid this phenomenon, the heating temperature of the front heating zone is usually reduced by adjusting the gas flow rate to prevent the rods from melting. However, this setting sometimes causes an increase in the temperature difference between the aluminum rod core and surface (i.e., the internal and external temperature difference), which is not conducive to the extrusion of high-end industrial materials. Summary of the Invention

[0004] Therefore, in order to solve the problem of large temperature difference between the core and surface of aluminum rods during preheating, this invention provides a heating furnace, the specific technical solution of which is as follows:

[0005] A heating furnace includes a transport device, a tilting device, and a positioning device. The tilting device and the positioning device are respectively connected to the transport device. The transport device includes a conveyor belt and a frame. The conveyor belt is drivenly connected to the frame. The positioning device is connected to the conveyor belt. The tilting device is used to tilt the aluminum rod on the positioning device.

[0006] The aforementioned heating furnace is equipped with a flipping device and a positioning device. The positioning device is connected to the conveyor belt. The flipping device is used to flip the aluminum rod on the positioning device, so that the aluminum rod on the positioning device is heated more evenly. This avoids the side of the aluminum rod that is in contact with the conveyor belt of the transport device from being unable to undergo the preheating process. Specifically, since the temperature on the side of the aluminum rod that is in contact with the conveyor belt of the transport device will be conducted to the conveyor belt, the temperature on this side of the aluminum rod is lower. Therefore, flipping the aluminum rod can prevent the rod from melting and solve the problem of large temperature difference between the core and surface of the aluminum rod.

[0007] Furthermore, the transport device also includes a drive mechanism, which is connected to the frame and to the transmission track drive.

[0008] Furthermore, the transport device also includes an adjustment mechanism connected to the frame.

[0009] Furthermore, the flipping device includes a mounting frame, a lifting device, a flipping mechanism, and a clamping mechanism. The mounting frame is connected to the frame, and the lifting device, the flipping mechanism, and the clamping mechanism are respectively connected to the mounting frame. The lifting device is driven to the flipping mechanism, and the flipping mechanism is driven to the clamping mechanism. The clamping mechanism is used to clamp the aluminum rod on the positioning device.

[0010] Furthermore, the lifting device includes a cylinder and a mounting block. The cylinder is connected to the mounting frame, the cylinder is driven to the mounting block, and the mounting block is connected to the tilting mechanism.

[0011] Furthermore, the flipping mechanism includes a flipping motor and a flipping connecting plate. One end of the flipping motor is connected to the mounting block, and the other end of the flipping motor is driven to the flipping connecting plate. The flipping connecting plate is connected to the clamping mechanism.

[0012] Furthermore, the clamping mechanism includes a clamping motor and a clamping end. One end of the clamping motor is connected to the flipping connecting plate, and the other end of the clamping motor is driven to the clamping end. The clamping end is used to clamp the aluminum rod on the positioning device.

[0013] Furthermore, the positioning device includes a connecting frame, a positioning rod, and a rotating frame. The connecting frame is connected to the transmission track, the rotating frame is connected to the connecting frame, and the positioning rod is rotatably connected to the rotating frame.

[0014] Furthermore, the positioning rod includes an abutting end and a swinging end. The center point of the positioning rod is far away from the connection point between the positioning rod and the rotating frame, the abutting end is close to the connection point between the positioning rod and the rotating frame, and the swinging end is close to the center point of the positioning rod.

[0015] Furthermore, the positioning device also includes two anti-slip blocks, which are respectively connected to the abutment end and the swing end. Attached Figure Description

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] In this invention, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0030] like Figure 1-3 As shown, a heating furnace according to one embodiment of the present invention includes a transport device 1, a tilting device 2, and a positioning device 3. The tilting device 2 and the positioning device 3 are respectively connected to the transport device 1. The transport device 1 includes a transmission track 11 and a frame 13. The transmission track 11 is connected to the frame 13 in a transmission manner. The positioning device 3 is connected to the transmission track 11. The tilting device 2 is used to tilt the aluminum rod on the positioning device 3.

[0031] The aforementioned heating furnace is equipped with a flipping device 2 and a positioning device 3. The positioning device 3 is connected to the conveyor belt 11. The flipping device 2 is used to flip the aluminum rod on the positioning device 3, so that the aluminum rod on the positioning device 3 is heated more evenly. This avoids the side of the aluminum rod that is in contact with the conveyor belt 11 of the transport device 1 from not being able to undergo the preheating process. Specifically, since the temperature on the side of the aluminum rod that is in contact with the conveyor belt 11 of the transport device 1 will be conducted to the conveyor belt 11, the temperature on this side of the aluminum rod is lower. Therefore, flipping the aluminum rod can avoid melting and solve the problem of large temperature difference between the core and surface of the aluminum rod.

[0032] like Figure 3 As shown, in one embodiment, the transport device 1 further includes a drive mechanism 12, which is connected to the frame 13 and driven by the transmission track 11. Thus, the drive mechanism 12 can drive the transmission track 11 to perform the transmission process.

[0033] like Figure 3 As shown, in one embodiment, the transport device 1 further includes an adjustment mechanism 14, which is connected to the frame 13. Thus, by adjusting the adjustment mechanism 14, the overall spatial position of the transport device 1 can be adjusted.

[0034] Preferably, by adjusting the adjusting mechanism 14, the height of the feeding end of the conveying device 1 is higher than the height of the unloading end of the conveying device 1, so as to facilitate the feeding process of the aluminum rod that has completed the preheating process by the mechanism of the next station.

[0035] like Figure 1 as well as Figure 4As shown, in one embodiment, the flipping device 2 includes a mounting frame 21, a lifting device 22, a flipping mechanism 23, and a clamping mechanism 24. The mounting frame 21 is connected to the frame 13. The lifting device 22, the flipping mechanism 23, and the clamping mechanism 24 are respectively connected to the mounting frame 21. The lifting device 22 is driven to the flipping mechanism 23, and the flipping mechanism 23 is driven to the clamping mechanism 24. The clamping mechanism 24 is used to clamp the aluminum rod on the positioning device 3. Thus, the lifting device 22 can drive the flipping mechanism 23 to perform a lifting process; the flipping mechanism 23 can drive the clamping mechanism 24 to perform a flipping process; and the clamping mechanism 24 can clamp the aluminum rod on the positioning device 3. The holding process; specifically, the positioning device 3 performs the positioning process for the aluminum rod, the transmission track 11 drives the positioning device 3 to move, the positioning device 3 moves the aluminum rod, the aluminum rod reaches the flipping device 2, the lifting device 22 first drives the flipping mechanism 23 to descend, then the clamping mechanism 24 clamps the aluminum rod on the positioning device 3, then the flipping mechanism 23 can drive the clamping mechanism 24 to perform the flipping process, then the clamping mechanism 24 drives the aluminum rod to flip, then the clamping mechanism 24 releases the clamping process on the aluminum rod on the positioning device 3, then the lifting device 22 drives the flipping mechanism 23 to rise and reset, finally realizing that the aluminum rod can be flipped through the flipping device 2.

[0036] like Figure 1 as well as Figure 4 As shown, in one embodiment, the lifting device 22 includes a cylinder 221 and a mounting block 222. The cylinder 221 is connected to the mounting frame 21 and is driven to the mounting block 222. The mounting block 222 is connected to the tilting mechanism 23. Thus, through the drive connection between the cylinder 221 and the mounting block 222, the cylinder 221 can drive the mounting block 222 to move. Through the connection between the mounting block 222 and the tilting mechanism 23, the mounting block 222 can drive the tilting mechanism 23 to move.

[0037] Preferably, the driving direction of the cylinder 221 is vertical, so that the cylinder 221 can drive the mounting block 222 to perform the lifting process, thereby enabling the mounting block 222 to drive the flipping mechanism 23 to perform lifting motion.

[0038] Preferably, the lifting device 22 further includes a guide rod 223, which is connected to the mounting frame 21. The guide rod 223 is vertically arranged and slidably connected to the mounting block 222. In this way, the guide rod 223 can guide the mounting block 222, thereby ensuring that the cylinder 221 drives the mounting block 222 to perform the lifting process without deviation.

[0039] like Figure 4-5As shown, in one embodiment, the flipping mechanism 23 includes a flipping motor 231 and a flipping connecting plate 232. One end of the flipping motor 231 is connected to the mounting block 222, and the other end of the flipping motor 231 is driven to the flipping connecting plate 232. The flipping connecting plate 232 is connected to the clamping mechanism 24. Thus, the flipping motor 231 can drive the flipping connecting plate 232 to perform the flipping process. Through the connection between the flipping connecting plate 232 and the clamping mechanism 24, the flipping connecting plate 232 can drive the clamping mechanism 24 to perform the flipping process.

[0040] like Figure 1 as well as Figure 4-5 As shown, in one embodiment, the clamping mechanism 24 includes a clamping motor 241 and a clamping end 242. One end of the clamping motor 241 is connected to the flip connecting plate 232, and the other end of the clamping motor 241 is driven to the clamping end 242. The clamping end 242 is used to clamp the aluminum rod on the positioning device 3. Thus, the clamping motor 241 can drive the clamping end 242 to perform the clamping process on the aluminum rod on the positioning device 3.

[0041] like Figure 6-7 As shown, in one embodiment, the positioning device 3 includes a connecting frame 31, a positioning rod 32, and a rotating frame 33. The connecting frame 31 is connected to the conveyor belt 11, the rotating frame 33 is connected to the connecting frame 31, and the positioning rod 32 is rotatably connected to the rotating frame 33. Thus, by connecting the rotating frame 33 to the connecting frame 31, the rotating frame 33 can be connected to the conveyor belt 11 through the connecting frame 31. By rotatably connecting the positioning rod 32 to the rotating frame 33, the positioning rod 32 can rotate around the connection point between the positioning rod 32 and the rotating frame 33. Ultimately, when the aluminum rod is fed to the positioning device 3, the positioning rod 32 and the rotating frame 33 rotate, causing one end of the positioning rod 32 to tilt up, thereby enabling the positioning device 3 to perform a positioning process on the aluminum rod.

[0042] Preferably, the connecting frame 31 is provided with a connecting hole 311, which is an elongated hole. A nut passes through the connecting hole 311 and is screwed onto the transmission track 11 to realize the connection between the connecting frame 31 and the transmission track 11.

[0043] Preferably, there is a gap between the nut and the connecting hole 311. In this way, when the positioning device 3 is transported to the bend of the transmission track 11, the connecting frame 31 of the positioning device 3 has room to move, which avoids the connecting frame 31 of the positioning device 3 from damaging the transmission track 11 and increases the service life of the transmission track 11.

[0044] like Figure 6As shown, in one embodiment, the positioning rod 32 includes an abutment end 321 and a swing end 322. The center point of the positioning rod 32 is far away from the connection point between the positioning rod 32 and the rotating frame 33. The abutment end 321 is close to the connection point between the positioning rod 32 and the rotating frame 33. The swing end 322 is close to the center point of the positioning rod 32. Thus, the height of the abutment end 321 is higher than the height of the swing end 322. When the aluminum rod is fed to the abutment end 321, the positioning rod 32 can buffer the aluminum rod.

[0045] Preferably, the rotating frame 33 is provided with an adjustment hole 331, and the nut passes through the adjustment hole 331 and is connected to the positioning rod 32. There are multiple adjustment holes 331, so that the connection position between the positioning rod 32 and the rotating frame 33 can be adjusted.

[0046] Preferably, there are multiple positioning devices 3, with two positioning devices 3 forming a group. The two positioning devices 3 in a group are symmetrically arranged, and the abutting end 321 of the two positioning devices 3 is located in the middle. In this way, the positioning device 3 can better buffer the aluminum rod.

[0047] like Figure 6 As shown, in one embodiment, the positioning device 3 further includes two anti-slip blocks 34, which are respectively connected to the abutment end 321 and the swing end 322, so as to prevent the aluminum rod from falling off the positioning device 3 during the transportation process of the transport device 1.

[0048] The working principle of this invention is as follows: An external feeding device feeds aluminum bars to a positioning device 3. The positioning device 3 positions the aluminum bars. A drive mechanism 12 drives a conveyor belt 11 for transport. The conveyor belt 11 drives the positioning device 3 to move, thereby moving the aluminum bars. The aluminum bars reach the flipping device 2. The cylinder 221 of the lifting device 22 is connected to the mounting block 222, which in turn drives the mounting block 222 to move. The mounting block 222 is connected to the flipping mechanism 23. Since the cylinder 221 is driven vertically, the mounting block 222 can drive the flipping mechanism 23 to move up and down. At this time, the lifting device 22 drives the flipping mechanism 23 to descend. Then, the flipping motor 231 drives the flipping connecting plate 232 to flip. The flipping connecting plate 232 is connected to the clamping mechanism 24, which allows the flipping connecting plate 232 to move up and down. The clamping mechanism 24 performs a flipping process, then clamps the aluminum rod on the positioning device 3. The flipping mechanism 23 then drives the clamping mechanism 24 to perform the flipping process, causing the clamping mechanism 24 to flip the aluminum rod, preventing the side of the aluminum rod in contact with the conveyor belt 11 of the transport device 1 from being unable to undergo the preheating process. Next, the clamping mechanism 24 releases its grip on the aluminum rod on the positioning device 3. Then, the lifting device 22 drives the flipping mechanism 23 to rise and reset, ultimately allowing the aluminum rod to be flipped through the flipping device 2. The driving mechanism 12 continues to drive the conveyor belt 11 for transport, and the conveyor belt 11 drives the positioning device 3 to move. The positioning device 3 carries the aluminum rod, and the aluminum rod reaches the bend of the conveyor belt 11, i.e., the unloading end. It is then rotatably connected to the rotating frame 33 via the positioning rod 32, facilitating the sliding of the aluminum rod onto the next station's conveyor device.

[0049] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
