Description

Technical Field

[0001] The utility model relates to the technical field of heating furnaces, in particular to a heating furnace for aluminum rod processing. Background Art

[0002] An aluminum rod heating furnace is an induction heating furnace specialized for heating aluminum rods, suitable for forging or extrusion after heating the aluminum rods. Due to the non-magnetic property of metallic aluminum, the design and manufacture of an aluminum rod heating furnace are different from those of induction heating furnaces for carbon steel and alloy steel. A unique design is required to ensure the smooth heating of aluminum rods and environmental protection and energy conservation.

[0003] During the heating process using an aluminum rod heating furnace, the aluminum rods need to be placed on the chain plate conveyor belt inside the furnace body. The conveyor belt will drive the aluminum rods to move from the feed inlet to the discharge outlet of the furnace body. However, when the aluminum rods move on the chain plate conveyor belt, they are prone to shift on the chain plate conveyor belt, which may cause the aluminum rods to skew, and further lead to material jamming, making it inconvenient for the normal output of aluminum rods. Summary of the Utility Model

[0004] The utility model provides a heating furnace for aluminum rod processing to solve the problem that when the aluminum rods move on the chain plate conveyor belt, they are prone to shift on the chain plate conveyor belt, which may cause the aluminum rods to skew, and further lead to material jamming, making it inconvenient for the normal output of aluminum rods.

[0005] To achieve the above object, the utility model adopts the following technical scheme: A heating furnace for aluminum rod processing, including a furnace body. A heating chamber is fixedly connected to the top of the inner wall of the furnace body. Two rollers are symmetrically and rotatably connected to both sides of the inner wall of the furnace body. The outer surfaces of the two rollers are provided with the same chain plate conveyor belt. A motor is arranged on one side of the furnace body. The output end of the motor is fixedly connected to one end of one of the rollers. A limiting device is arranged on the top of the chain plate conveyor belt. The limiting device includes two limiting plates, which are symmetrically arranged on the top of the chain plate conveyor belt. Three extension blocks are evenly arranged on the top of the limiting plate. The inner walls of the middle two extension blocks are respectively threadedly connected with a first threaded rod and a second threaded rod. The closer ends of the first threaded rod and the second threaded rod are fixedly connected. The thread sizes of the first threaded rod and the second threaded rod are the same and the directions are opposite. The outer surfaces of the first threaded rod and the second threaded rod are both arranged on the inner wall of the furnace body. An adjusting device is arranged at the bottom of the furnace body.

[0006] The effects achieved by the above components are as follows: By setting two limit plates, under the action of the first threaded rod and the second threaded rod, when the first threaded rod and the second threaded rod are rotated, the first threaded rod and the second threaded rod will respectively drive a limit plate connected to the extension block to move towards each other until one side of the two limit plates is about to abut against both ends of the aluminum rod, then the aluminum rod can be limited, which is beneficial to preventing the aluminum rod from skewing on the chain conveyor belt and causing material jamming, and facilitating the normal output of the aluminum rod.

[0007] Preferably, bearings are fixedly connected to the outer surfaces of the first threaded rod and the second threaded rod, and the outer surfaces of the bearings are fixedly connected to the inner wall of the furnace body.

[0008] The effects achieved by the above components are as follows: By setting the bearings, the friction between the first threaded rod and the second threaded rod and the furnace body can be reduced when rotating the first threaded rod and the second threaded rod, and thus it is more labor-saving when rotating the first threaded rod and the second threaded rod.

[0010] The effects achieved by the above components are as follows: By setting the operation blocks, rotating the operation blocks can drive the first threaded rod and the second threaded rod to rotate. At the same time, protrusions are arranged on the outer surfaces of the operation blocks, which can effectively increase the friction on the outer surfaces of the operation blocks and play an anti-slip role when rotating the operation blocks.

[0011] Preferably, round rods are symmetrically and slidably connected to the inner walls of the other four extension blocks, and both ends of the round rods are fixedly connected to both sides of the inner wall of the furnace body.

[0012] The effects achieved by the above components are as follows: By setting the round rods, when the two limit plates move under the action of the first threaded rod and the second threaded rod respectively, the extension blocks will be driven to slide synchronously on the outer surfaces of the round rods, which can play a role in limiting the limit plates.

[0013] Preferably, the same mounting plate is fixedly connected to one side of the three extension blocks, bolts are symmetrically inserted into the inner wall of the mounting plate, and the outer surfaces of the bolts are threadedly inserted into the inner wall of the limit plate.

[0014] The effects achieved by the above components are as follows: By setting the mounting plate, inserting the bolts into the inner wall of the mounting plate and rotating the bolts so that the bolts enter the inner wall of the limit plate, the mounting plate and the limit plate can be installed, and thus it is convenient to disassemble and replace the limit plate.

[0015] Preferably, the adjusting device includes four sliding rods. One ends of the four sliding rods are respectively fixedly connected to four corners of the bottom of the furnace body. A sleeve is slidably connected to the outer surface of each sliding rod. One ends of the four sleeves are fixedly connected to the same rectangular frame. Threaded insertion rods are symmetrically and fixedly connected to both sides of the rectangular frame. A round hole block is slidably connected to the outer surface of each threaded insertion rod. One side of the round hole block is fixedly connected to the outer surface of the furnace body.

[0016] The effects achieved by the above components are as follows: By providing the threaded insertion rods and pushing the threaded insertion rods to slide on the inner wall of the round hole blocks, the threaded insertion rods will drive the sleeves connected to the rectangular frame to slide synchronously on the outer surfaces of the sliding rods, thereby facilitating the corresponding adjustment of the height of the chain plate conveyor according to actual needs and improving the practicality of the heating furnace.

[0017] Preferably, nuts are provided on both sides of the round hole block, and the inner walls of the two nuts are threadedly connected to the outer surface of the threaded insertion rod.

[0018] The effects achieved by the above components are as follows: By providing two nuts and rotating the two nuts so that one side of a nut abuts against one side of the round hole block, the round hole block and the threaded insertion rod can be fixed, and thus the height of the furnace body can be fixed.

[0019] Preferably, a round block is fixedly connected to one end of the threaded insertion rod, and the outer diameter of the round block is larger than the outer diameter of the threaded insertion rod.

[0020] The effects achieved by the above components are as follows: By providing the round block, one end of the threaded insertion rod can be blocked, which is beneficial to preventing the nut from detaching from the threaded insertion rod due to misoperation.

Under the limitation of the round rod 27, the first threaded rod 23 and the second threaded rod 24 will respectively drive a limiting plate 21 connected to the extension block 22 to move towards each other until one side of the two limiting plates 21 is about to abut against the two ends of the aluminum rod, then the aluminum rod can be limited, which is beneficial to preventing the aluminum rod from skewing on the chain plate conveyor belt 6 and causing material jamming; when it is necessary to install the limiting plate 21, insert the bolt 29 into the inner wall of the mounting plate 28 and rotate the bolt 29 so that the bolt 29 enters the inner wall of the limiting plate 21, then the mounting plate 28 and the limiting plate 21 can be installed, and thus it is convenient to disassemble and replace the limiting plate 21; when it is necessary to adjust the height of the furnace body 1, push the threaded insertion rod 34 to slide in the inner wall of the round hole block 35, and the threaded insertion rod 34 will drive the sleeve 32 connected to the rectangular frame 33 to slide synchronously on the outer surface of the sliding rod 31 until the furnace body 1 reaches the appropriate height. Rotate the two nuts 36 so that one side of the nut 36 abuts against one side of the round hole block 35, then the round hole block 35 and the threaded insertion rod 34 can be fixed, and thus the height of the furnace body 1 can be fixed.
