Description

Technical Field

[0001] The present invention relates to the technical field of aluminum coil annealing, and particularly relates to an aluminum coil annealing device. Background Art

[0002] Aluminum coil annealing refers to the process of placing an aluminum coil in a specific environment, heating it to a certain temperature, holding it for a period of time, and then slowly cooling it. This process can soften the aluminum coil, reduce its hardness, improve plasticity and toughness, and at the same time make the chemical composition more uniform, so as to achieve the desired physical properties. Therefore, an aluminum coil annealing device is needed.

[0003] Most traditional aluminum coil annealing devices directly move the unopened aluminum coil to the annealing table or annealing furnace for heating and annealing by using a material handling trolley. Although this method has a relatively high processing efficiency, since the aluminum coil is annealed without being opened, it is extremely easy to cause uneven heating of the aluminum plates on the inner and outer sides of the aluminum coil, resulting in a relatively obvious difference in the quality of the aluminum plates on the inner and outer sides of the aluminum coil, and further affecting the product quality of the entire aluminum coil. In view of the disadvantages of traditional aluminum coil annealing devices, those skilled in the art have proposed an aluminum coil annealing device. Summary of the Invention

[0022] Compared with the prior art, the beneficial effects of the present invention are;

[0023] 1. In the present invention, a fixed base, an annealing furnace, and a rewinding and unwinding reel stand are provided. The annealing furnace is fixedly installed on the set fixed base, and the inner cavity of the annealing furnace is divided into a heating chamber, a heat preservation chamber, and a cooling chamber. First mounting racks are symmetrically installed in the set heating chamber, and gas tank seats are symmetrically installed on the opposite sides of the two first mounting racks. A number of ignition burners are evenly installed on the gas tank seats. A gas pipe is connected and communicated with the inner cavity of the gas tank seat.

A number of air nozzles are installed on the air tank seat. Air-cooling fans are symmetrically installed on the annealing furnace. One end of an air pipe is connected and communicated with the output end of the air-cooling fan, and the other end of the air pipe is connected and communicated with the inner cavity of the air tank seat. On the other hand, rewinding and unwinding reel stands are symmetrically arranged on both sides of the top surface of the fixed base, and a rewinding and unwinding reel rotating shaft is installed on the rewinding and unwinding reel stand. One end of the rewinding and unwinding reel rotating shaft on one side is connected to the output end of a rewinding and unwinding reel motor. An adjusting storage groove is formed on the rewinding and unwinding reel rotating shaft, a guiding cross pin is inserted in the adjusting storage groove, and an adjusting fixing pin is fixedly installed at one end of the guiding cross pin. At the same time, a fourth bearing bracket is fixedly installed on the side wall of the rewinding and unwinding reel rotating shaft, and an adjusting lead screw is installed on the fourth bearing bracket. A connecting frame is fixedly installed on one side of the adjusting fixing pin, a second lead screw sleeve is fixedly installed on the connecting frame, and the second lead screw sleeve is matched with the adjusting lead screw. During use, workers can place the aluminum coil to be annealed in the center of the rewinding and unwinding reel stand on one side. Then, the user can adjust according to the width of the aluminum coil, and then rotate the adjusting lead screw to drive the adjusting fixing pin to move along the adjusting storage groove until the adjusting fixing pin is correspondingly inserted into the center of the winding sleeve of the aluminum coil, and then the aluminum coil can be placed on the rewinding and unwinding reel rotating shaft. After the aluminum coil is unrolled, it passes through the heating chamber, the heat preservation chamber, and the cooling chamber in sequence. The gas pipe and the ignition burner are used to heat and anneal the unrolled aluminum coil. Then, the aluminum coil heated to a certain temperature is moved into the heat preservation chamber, and the electric heating rods are used to realize the heat preservation heating of the aluminum coil. After heat preservation for a certain period of time, the aluminum coil enters the cooling chamber again. The air-cooling fan is started through the control panel, and the outside air is blown onto the surface of the aluminum coil through the air pipe, the air tank seat, and the air nozzles to realize the uniform cooling of the aluminum coil after heat preservation. The obtained aluminum coil is rewound again through the rewinding and unwinding reel stand installed on the other side, so that the inner and outer sides of the aluminum coil are evenly heated during annealing, ensuring that the quality of the inner and outer side aluminum plates of the aluminum coil is more uniform, improving the product quality of the entire aluminum coil, and being applicable to the annealing operation of aluminum coils with different widths, with stronger applicability.

[0024] 2. In the present invention, a gripping and moving plate, a gripping and moving track, and a fixing base are provided. The inner wall of the annealing furnace is symmetrically and fixedly installed with the gripping and moving track. The annealing furnace is internally provided with the gripping and moving plate.

The top surface of the gripping and moving plate is provided with an adjusting chute, and adjusting sliders are symmetrically snap-fitted in the adjusting chute. The top ends of the adjusting sliders are fixedly installed with the fixing base. The top surface of the fixing base is fixedly installed with a nut, and a fastening bolt is screwed and installed in the nut. The bottom end of the fastening bolt is fixedly installed with a clamping plate. The bottom surface of the clamping plate is provided with anti-slip lines. After the aluminum coil is uncoiled, the worker can place one end of the aluminum coil on the top surface of the gripping and moving plate, and then adjust the distance between the two fixing bases according to the width of the aluminum coil. By rotating the fastening bolt, the clamping plate clamps and fixes one end of the aluminum coil. On the other hand, feeding and discharging openings are symmetrically provided on both sides of the annealing furnace. A second bearing bracket is fixedly installed on the feeding and discharging openings. A pulling rotating shaft is installed on the second bearing bracket. One end of a pulling steel cable is wound around the pulling rotating shaft. The other ends of the pulling steel cables are symmetrically fixedly connected to both sides of the moving slider. A hand crank is fixedly installed at one end of the pulling rotating shaft. Therefore, the worker can drive the pulling rotating shaft to rotate through the hand crank, so as to pull the gripping and moving plate to move along the gripping and moving track, and thus one end of the aluminum coil can pass through the inner cavity of the annealing furnace without being pulled by the coiling equipment on the other side. The operation and use are convenient, ensuring the annealing of the entire aluminum coil, and the practicability is stronger.

[0025] 3. In the present invention, an adjustment mounting frame and a support roller are provided. Inner walls of two winding and unwinding frames are fixedly installed with first bearing frames. Guide slide rods are symmetrically and fixedly installed on two first bearing frames. A support lead screw is installed on one side of the first bearing frame, and the bottom end of the support lead screw is connected to the output end of a servo motor. An adjustment mounting frame is arranged between two first bearing frames, and support rollers are symmetrically installed in the adjustment mounting frame. Connecting blocks are symmetrically and fixedly installed on two side walls of the adjustment mounting frame. A first lead screw sleeve is fixedly installed on the connecting block, and the first lead screw sleeve is matched with the support lead screw. Guide sliding sleeves are symmetrically and fixedly installed on two connecting blocks, and guide slide rods are sleeved in the guide sliding sleeves. Therefore, when workers pick up and place aluminum coils, they can first place the aluminum coils on two support rollers, and then start the servo motor through the control panel to drive the support lead screw to rotate, so as to facilitate aligning the aluminum coils with the winding and unwinding rotating shafts, completing the installation or disassembly of the aluminum coils. During the annealing winding and unwinding process of the aluminum coils, the control panel can control the support lead screw to rotate at a certain speed, so that the adjustment mounting frame moves along the direction of the guide slide rod, so that the support rollers are always in contact with the bottom surface of the aluminum coils during winding and unwinding, so as to prevent the aluminum coils from loosening during unwinding or winding, ensuring the smoothness of the aluminum coils during annealing and ensuring the rapid winding of the aluminum coils after annealing. A third bearing frame is fixedly installed on the top surface of the feeding and discharging port, and a guide roller is installed on the third bearing frame, which can guide the aluminum plates during winding and unwinding, so that they pass through the inner cavity of the annealing furnace smoothly, ensuring that the heating, heat preservation and cooling on both sides are more uniform, and further improving the quality of the annealed aluminum coil products.

[0050] Working principle: In the present invention, there are a fixed base 1, an annealing furnace 2 and a pay-off and take-up reel 12. The fixed base 1 is fixedly installed with the annealing furnace 2. The inner cavity of the annealing furnace 2 is divided into a heating chamber 3, a heat preservation chamber 4 and a cooling chamber 6. In the heating chamber 3, first mounting frames 16 are symmetrically installed. On the opposite sides of the two first mounting frames 16, gas tank seats 13 are symmetrically installed. A number of ignition burners 15 are evenly installed on the gas tank seats 13. The inner cavity of the gas tank seat 13 is connected and communicated with a gas pipe 14. In the inner cavity of the heat preservation chamber 4, second mounting frames 5 are symmetrically and fixedly installed. A number of electric heating rods 17 are evenly installed on the second mounting frames 5. In the cooling chamber 6, third mounting frames 8 are symmetrically and fixedly installed. An air tank seat 19 is installed on the third mounting frames 8. A number of air nozzles 21 are installed on the air tank seat 19.

An adjustment storage groove 48 is formed on the pay-off and take-up reel rotating shaft 35. A guiding cross pin 49 is inserted into the adjustment storage groove 48. One end of the guiding cross pin 49 is fixedly installed with an adjustment fixing pin 23. At the same time, a fourth bearing bracket 50 is fixedly installed on the side wall of the pay-off and take-up reel rotating shaft 35. An adjustment lead screw 51 is installed on the fourth bearing bracket 50. One side of the adjustment fixing pin 23 is fixedly installed with a connecting frame 52. A second lead screw sleeve 53 is fixedly installed on the connecting frame 52. The second lead screw sleeve 53 is matched with the adjustment lead screw 51. During use, workers can place the aluminum coil to be annealed in the center of the pay-off and take-up reel 12 on one side. Then, the user can adjust according to the width of the aluminum coil, and then rotate the adjustment lead screw 51 to drive the adjustment fixing pin 23 to move along the adjustment storage groove 48 until the adjustment fixing pin 23 is correspondingly inserted into the center of the winding sleeve of the aluminum coil, and then the aluminum coil can be placed on the pay-off and take-up reel rotating shaft 35. After the aluminum coil is unrolled, it passes through the heating chamber 3, the heat preservation chamber 4 and the cooling chamber 6 in sequence. The gas pipe 14 and the ignition burners 15 are used to heat and anneal the unrolled aluminum coil. Then, the aluminum coil heated to a certain temperature is moved into the heat preservation chamber 4, and the electric heating rods 17 are used to realize the heat preservation heating of the aluminum coil. After heat preservation for a certain period of time, the aluminum coil enters the cooling chamber 6 again. The air-cooling fan 7 is started through the control panel 26, and the outside air is blown onto the surface of the aluminum coil through the air pipe 20, the air tank seat 19 and the air nozzles 21 to realize the uniform cooling of the heat-preserved aluminum coil. The obtained aluminum coil is re-wound through the pay-off and take-up reel 12 installed on the other side, so that the aluminum plates on the inner and outer sides of the aluminum coil are evenly heated during annealing, ensuring that the quality of the aluminum plates on the inner and outer sides of the aluminum coil is more uniform, improving the product quality of the whole aluminum coil, and being able to be applicable to aluminum coils of different widths for annealing operations, with stronger applicability.In addition, in the present invention, there are provided a gripping and moving plate 28, a gripping and moving track 18 and a fixed seat 33.

Both ends of the gripping and moving plate 28 are symmetrically and fixedly installed with moving sliders 29, and the moving sliders 29 are snap-fitted inside the gripping and moving track 18. An adjusting chute 31 is formed on the top surface of the gripping and moving plate 28. Adjusting sliders 32 are symmetrically snap-fitted inside the adjusting chute 31, and a fixed seat 33 is fixedly installed at the top end of the adjusting slider 32.

The bottom end of the fastening bolt 43 is fixedly installed with a clamping plate 34. Anti-slip lines 44 are formed on the bottom surface of the clamping plate 34. After the aluminum coil is uncoiled, the worker can place one end of the aluminum coil on the top surface of the gripping and moving plate 28, and then adjust the distance between the two fixed seats 33 according to the width of the aluminum coil. By rotating the fastening bolt 43, the clamping plate 34 clamps and fixes one end of the aluminum coil. On the other hand, feeding and discharging openings 45 are symmetrically formed on both sides of the annealing furnace 2. A second bearing bracket 25 is fixedly installed on the feeding and discharging opening 45, and a pulling rotating shaft 22 is installed on the second bearing bracket 25. One end of a pulling steel cable 30 is wound around the pulling rotating shaft 22. The other ends of the pulling steel cable 30 are symmetrically fixedly connected to both sides of the moving slider 29. A hand crank 27 is fixedly installed at one end of the pulling rotating shaft 22. Therefore, the worker can drive the pulling rotating shaft 22 to rotate through the hand crank 27, so as to pull the gripping and moving plate 28 to move along the gripping and moving track 18, and one end of the aluminum coil can pass through the inner cavity of the annealing furnace 2 without being pulled by the winding equipment on the other side. The operation is convenient, which ensures the annealing of the entire aluminum coil, has stronger practicability. At the same time, in the present invention, there are provided an adjusting installation frame 11 and a supporting roller 36. First bearing brackets 10 are fixedly installed on the inner walls of the two winding and unwinding frames 12. Guide sliding rods 40 are symmetrically and fixedly installed on the two first bearing brackets 10. A supporting lead screw 38 is installed on one of the first bearing brackets 10, and the bottom end of the supporting lead screw 38 is connected to the output end of a servo motor 9. An adjusting installation frame 11 is arranged between the two first bearing brackets 10, and supporting rollers 36 are symmetrically installed inside the adjusting installation frame 11. Connecting blocks 37 are symmetrically and fixedly installed on the side walls of both sides of the adjusting installation frame 11. A first lead screw sleeve 39 is fixedly installed on the connecting block 37, and the first lead screw sleeve 39 is matched with the supporting lead screw 38. Guide sliding sleeves 41 are symmetrically and fixedly installed on the two connecting blocks 37, and the guide sliding rods 40 are sleeved inside the guide sliding sleeves 41. Therefore, when the worker takes and places the aluminum coil, the aluminum coil can be first placed on the two supporting rollers 36, and then the servo motor 9 is started through the control panel 26 to drive the supporting lead screw 38 to rotate, so as to facilitate the alignment of the aluminum coil with the winding and unwinding rotating shaft 35, and complete the installation or disassembly of the aluminum coil. During the annealing, winding and unwinding process of the aluminum coil, the control panel 26 can control the supporting lead screw 38 to rotate at a certain speed, so that the adjusting installation frame 11 moves along the direction of the guide sliding rod 40, so that the supporting roller 36 is always in contact with the bottom surface of the winding and unwinding aluminum coil.To prevent the aluminum coil from loosening during unwinding or rewinding, ensure the smooth unwinding and annealing of the aluminum coil, and ensure the rapid winding of the aluminum coil after annealing, a third bearing bracket 46 is fixedly installed on the top surface of the inlet and outlet 45, and a guide roller 47 is installed on the third bearing bracket 46, which can guide the aluminum plate during unwinding and rewinding, enabling it to pass through the inner cavity of the annealing furnace 2 smoothly, ensuring more uniform heating, heat preservation, and cooling on both sides, and further improving the quality of the annealed aluminum coil product.
