Technical Field

[0001] The invention relates to the field of annealing furnaces, in particular to a continuous annealing furnace and a continuous production method. Background Art

[0002] Annealing furnace is a kind of equipment used for heat treatment of metal materials. Its main function is to keep the metal at high temperature for a certain period of time by heating and heat preservation, and then slowly cool it, so as to eliminate the internal stress in the material, improve its organizational structure, and then improve the plasticity and toughness of the material; the existing annealing furnace is provided with an adjustment mechanism, so that by starting motor one, motor one drives threaded rod one to rotate, threaded rod one drives extension block to move, and extension block drives annealing box downward, so that annealing box contacts with moving plate, so as to heat and anneal the metal material on the moving plate; by setting a moving mechanism, motor two can be started, motor two drives threaded rod two to rotate, threaded rod two drives moving plate to move, so that moving plate moves to the bottom of annealing box, so as to load and unload metal materials; by setting rectangular slots and rectangular limit blocks, metal materials can be limited in the rectangular limit blocks to avoid the movement of the moving plate The rectangular slot can improve the air tightness of the aluminum tube roller during the heating process; after the heating is completed, the suction pump is started, and the suction pump presses the hot air in the annealing box into the insulation box, reducing the waste of heat in the annealing furnace; however, after the annealing work is completed, the existing annealing furnace is usually provided with a cooling mechanism, so that the water pump can be started, and the water pump sprays the water in the water tank onto the heated metal material for cooling, and the cooled water flows from the water flow hole into the water collection tank for collection, which is convenient for recycling. However, after the cooling work is completed, the surface of the metal material will be wet, and an additional drying mechanism is required to dry the cooled metal material; and when the metal material is heated and annealed, because the bottom of the metal material is in contact with the moving plate, the bottom of the metal material cannot be effectively heated and annealed like other parts.

[0013] The present invention also provides a continuous production method of a continuous annealing furnace, which is characterized by comprising the following specific steps:

[0014] S1. When in use, place the metal materials in four groups of working boxes in sequence, start the servo motor to drive the rotating frame to rotate, and the rotation of the rotating frame will drive the four groups of working boxes to rotate, and each time the servo motor is started to control the rotating frame to rotate 90 degrees, so that the four groups of working boxes are moved to the bottom of the annealing box and the top of the cooling box in sequence;

[0015] S2, when the working box moves to the bottom of the annealing box, the second motor is started to drive the annealing assembly to move downward and the auxiliary assembly to move upward, so that the upper end of the working box is inserted into the annealing box, and the multiple sets of sealing rods are moved upward and inserted into the through holes opened in the corresponding working boxes, and then the metal material in the working box is heated by the annealing box. In this process, the multiple sets of sealing rods are continuously moved up and down, and the continuous up and down movement of the multiple sets of sealing rods will continuously lift up the metal material in the working box, so as to prevent the bottom of the metal material from contacting the working box for a long time, thereby preventing the bottom of the metal material from being heated poorly;

[0016] S3. When the working box moves to the top of the cooling box, the water pump is started to pump out the water in the cooling box and spray it from the two sets of nozzles. The water sprayed from the two sets of nozzles will spray on the metal material in the working box, thereby cooling the heated metal material. The cooled water will drip downward from the through hole and drip into the collection frame above the filter cloth. When the water cools the metal material and drips downward, it will inevitably bring impurities and some oxides attached to the surface of the metal material into the collection frame. The cooled water can be filtered through the filter cloth, and the filtered water returns to the cooling box. When the water cools the metal material, the temperature of the water will inevitably rise. When the water returns to the cooling box, it will inevitably increase the temperature of the water in the cooling box. At this time, the rotation of the stirring shaft drives the stirring member to rotate. The rotation of the stirring member will continuously stir the water in the cooling box, thereby accelerating the drop in the water temperature in the cooling box, thereby ensuring the cooling effect. At the same time, the fan blades rotate to air-dry the cooled and moist metal material.

[0017] S4. When the metal material in the working box directly below the annealing box is heated, start the suction pump to press the hot air in the annealing box into the insulation box. When a new working box moves to the bottom of the annealing box, start the exhaust pump to press the hot air in the insulation box back into the annealing box.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. When the present invention is used, the sealing rod is driven to move up and down by the motor 1, and the up and down movement of the sealing rod will continuously lift up the metal material in the working box to prevent the bottom of the metal material from contacting the working box for a long time, thereby preventing the bottom of the metal material from being heated poorly; similarly, the stirring member is driven to rotate by the motor 1, and the rotation of the stirring member will continuously stir the water in the cooling box, thereby accelerating the decrease in the temperature of the water in the cooling box, thereby ensuring the cooling effect; and the rotation of the stirring member will drive the elastic head to rotate, and the elastic head will contact the bottom of the filter cloth during the rotation process, and when contacting the bottom of the filter cloth, the elastic head will slightly lift up the filter cloth, so that The filter cloth vibrates to speed up the filtering speed; similarly, the fan blades are driven to rotate under the drive of motor one, and the rotation of the fan blades can air-dry the moist metal material after cooling; when the present invention is used, under the drive of motor one, not only the heating effect of the metal material in the working box below the annealing box is ensured, but also the metal material in the working box above the cooling box can be air-dried after cooling, and the water in the cooling box can be stirred to reduce the temperature of the water in the cooling box, thereby ensuring the cooling effect, and at the same time making the filter cloth vibrate to speed up the filtering speed, multiple effects are achieved through the drive of a group of motors one, while reducing the use cost and improving the work efficiency.

[0020] 2. The through hole on the working box of the present invention reserves space for the upward movement of the sealing rod during heating, and the sealing rod will block the through hole to prevent heat from overflowing from the through hole. It also reserves space for cooling water to drip back into the cooling box during cooling, so that the water in the working box can drip back into the cooling box through the through hole, thereby realizing the recycling of water.

[0040] The present invention also provides a continuous production method of a continuous annealing furnace, which is characterized by comprising the following specific steps:

[0041] S1. When in use, place the metal materials in the four groups of working boxes 30 in sequence, start the servo motor 25 to drive the rotating frame 29 to rotate, and the rotation of the rotating frame 29 will drive the four groups of working boxes 30 to rotate, and each time the servo motor 25 is started to control the rotating frame 29 to rotate 90 degrees, so that the four groups of working boxes 30 are moved to the bottom of the annealing box 501 and the top of the cooling box 34 in sequence;

[0042] S2, when the working box 30 moves to the bottom of the annealing box 501, the motor 21 is started to drive the annealing assembly 5 to move downward and the auxiliary assembly 6 to move upward, so that the upper end of the working box 30 is inserted into the annealing box 501, and the multiple sets of sealing rods 604 are moved upward and inserted into the corresponding through holes 31 of the working box 30, and then the metal material in the working box 30 is heated by the annealing box 501, and in this process, the multiple sets of sealing rods 604 are continuously moved up and down, and the continuous up and down movement of the multiple sets of sealing rods 604 will continuously lift up the metal material in the working box 30, so as to prevent the bottom of the metal material from contacting the working box 30 for a long time, thereby preventing the bottom of the metal material from being heated poorly;

[0043] S3. When the working box 30 moves to the top of the cooling box 34, the water pump 36 is started to pump out the water in the cooling box 34 and spray it out from the two sets of nozzles 39. The water sprayed by the two sets of nozzles 39 will spray on the metal material in the working box 30, thereby cooling the heated metal material. The cooled water will drip downward from the through hole 31 and drip into the collection frame 44 and above the filter cloth 43. When the water cools the metal material and drips downward, it is inevitable that impurities and some oxides attached to the surface of the metal material will be brought into the collection frame 44 and passed through the filter cloth. 43 can filter the cooled water, and the filtered water returns to the cooling box 34. When the water cools the metal material, the temperature of the water will inevitably rise. When the water returns to the cooling box 34, the temperature of the water in the cooling box 34 will inevitably increase. At this time, the stirring shaft 12 rotates to drive the stirring member 41 to rotate. The stirring member 41 rotates to continuously stir the water in the cooling box 34, thereby accelerating the decrease of the water temperature in the cooling box 34, thereby ensuring the cooling effect. At the same time, the fan blades 11 rotate to air-dry the cooled and wet metal material.

[0044] S4. When the metal material in the working box 30 directly below the annealing box 501 is completely heated, the suction pump 503 is started to press the hot air in the annealing box 501 into the insulation box 502. When a new working box 30 moves to the bottom of the annealing box 501, the exhaust pump 504 is started to press the hot air in the insulation box 502 back into the annealing box 501.

[0045] Working principle of the present invention: when in use, metal materials are placed in four groups of working boxes 30 in sequence, and the servo motor 25 is started to drive the rotating frame 29 to rotate. The rotation of the rotating frame 29 will drive the four groups of working boxes 30 to rotate, and each time the servo motor 25 is started to control the rotating frame 29 to rotate 90 degrees, so that the four groups of working boxes 30 are moved to the bottom of the annealing box 501 and the top of the cooling box 34 in sequence, so as to achieve continuous production; it should be noted that the servo motor 25 adopts closed-loop control system, high-precision encoder, digital signal processing, high response speed and good mechanical structure and other technologies, so that each time the servo motor 25 is started, it can accurately drive the rotating frame 29 to rotate 90 degrees;

[0046] When the working box 30 moves to the bottom of the annealing box 501, the second motor 21 is started to drive the bidirectional screw 3 to rotate. The rotation of the bidirectional screw 3 will drive the two sets of lifting blocks 4 to approach each other along the two sets of guide rods 22, thereby driving the annealing assembly 5 to move down and the auxiliary assembly 6 to move up, until a set of lifting blocks 4 fixedly connected to the annealing assembly 5 contacts the two sets of limit rings 23. At this time, the upper end of the working box 30 is inserted into the annealing box 501, and the multiple sets of sealing rods 604 are moved up and inserted into the corresponding through holes 31 opened in the working box 30. After that, the metal material in the working box 30 can be heated by heating the annealing box 501; and when the auxiliary assembly 6 moves up, the hexagonal rod at the lower end of the rotating member 608 will slide along the hexagonal groove opened on the inner side of the rotating shaft 17, and the hexagonal rod at the lower end of the rotating member 608 will not be separated from the hexagonal groove opened on the inner side of the rotating shaft 17;

[0047] In this process, the starting motor 15 drives the stirring shaft 12 to rotate. The stirring shaft 12 rotates and drives the two sets of mutually meshing bevel gears 20, which drives the rotating shaft 16 to rotate. The rotating shaft 16 rotates and drives the two sets of sprockets 2 18 and chains 1 19, which drives the rotating shaft 2 17 to rotate. The rotating shaft 2 17 rotates and drives the rotating member 608 to rotate. The rotating member 608 rotates and drives the rotating rod 2 607 to rotate under the transmission of the two sets of mutually meshing bevel gears 3 609. The rotating rod 2 607 rotates and drives the elliptical wheel 6 10 rotates. Due to the special shape of the elliptical wheel 610, and the outer side of the elliptical wheel 610 slides and fits the top of the auxiliary plate 601 and the bottom of the movable plate 603, and under the elastic action of the spring 605, the rotation of the elliptical wheel 610 will cause the movable plate 603 to move up and down continuously. The up and down movement of the movable plate 603 will drive the sealing rod 604 to move up and down. The up and down movement of the sealing rod will continuously lift up the metal material in the working box 2, preventing the bottom of the metal material from contacting the working box 30 for a long time, thereby preventing the bottom of the metal material from being heated poorly.

[0048] When the heating work is completed, the motor 21 is started again to drive the annealing assembly 5 to move up and the auxiliary assembly 6 to move down, so that the working box 30 of the heating can rotate away;

[0049] When the heated working box 30 moves to the top of the cooling box 34, the water pump 36 is started to pump out the water in the cooling box 34 and spray it out from the two sets of nozzles 39. The water sprayed from the two sets of nozzles 39 will be sprayed on the metal material in the working box 30, thereby cooling the heated metal material. After a certain amount of water is sprayed, the water pump 36 stops working, and the cooled water will drip downward from the through hole 31 and drip into the collecting frame 44 and be above the filter cloth 43. When the water cools the metal material and drips downward, it is inevitable that impurities attached to the surface of the metal material and some oxides will be brought into the collecting frame 44. The cooled water can be filtered through the filter cloth 43, and the filtered water returns to the cooling box 34. When the water cools the metal material, the temperature of the water will inevitably rise. When the water returns to the cooling box 34, it will inevitably increase the temperature of the water in the cooling box 34. At this time, the stirring shaft The rotation of the stirring member 41 drives the stirring member 41 to rotate. The rotation of the stirring member 41 will continuously stir the water in the cooling box 34, thereby accelerating the decrease in the temperature of the water in the cooling box 34, thereby ensuring the cooling effect. The rotation of the stirring member 41 will drive the elastic head 42 to rotate. The elastic head 42 will contact the bottom of the filter cloth 43 during the rotation process. When contacting the bottom of the filter cloth 43, the elastic head 42 will slightly push up the filter cloth 43 (the filter cloth 43 is made of nylon filter cloth, which has a certain elasticity), so that the filter cloth 43 shakes and accelerates the filtering speed; at the same time, the stirring shaft 12 rotates and drives the rotating rod 8 to rotate under the transmission of the two sets of sprockets 13 and the chain 14. The rotating rod 8 rotates and drives the fan shaft 9 under the transmission of the two sets of mutually meshing bevel gears 10. The rotation of the fan shaft 9 drives the fan blades 11 to rotate. The rotation of the fan blades 11 can air-dry the wet metal material after cooling;

[0050] It should be noted that when the metal material in the working box 30 directly below the annealing box 501 is heated, the suction pump 503 is started to press the hot air in the annealing box 501 into the heat preservation box 502. When a new working box 30 moves to the bottom of the annealing box 501, the exhaust pump 504 is started to press the hot air in the heat preservation box 502 back into the annealing box 501, thereby reducing the waste of heat.

[0051] During the use of the present invention, while the annealing assembly 5 is heating the metal material in a group of working boxes 30, a group of heated working boxes 30 will be located directly above the cooling box 34 and will be cooled and air-dried.

[0052] It should be noted that the present invention needs to be connected to a suitable external power supply when in use, and the external power supply provides power support for the work of the servo motor 25, the motor 21, the water pump 36, the motor 15, the air suction pump 503, the air outlet pump 504, etc.; the present invention needs to be connected to various suitable external controllers when in use, and the work of the servo motor 25, the motor 21, the water pump 36, the motor 15, the air suction pump 503, the air outlet pump 504, etc. can be controlled by the external suitable controller;

It cannot be determined that the specific implementation of the present invention is limited to these descriptions.

When in use, metal materials are placed in four groups of working boxes (30) in sequence, and the servo motor (25) is started to drive the rotating frame (29) to rotate. The rotation of the rotating frame (29) will drive the four groups of working boxes (30) to rotate, and each time the servo motor (25) is started to control the rotating frame (29) to rotate 90 degrees, so that the four groups of working boxes (30) are moved in sequence to the bottom of the annealing box (501) and the top of the cooling box (34); S2, when the working box (30) moves to the bottom of the annealing box (501), the second motor (21) is started to drive the annealing assembly (5) to move downward and the auxiliary assembly (6) to move upward, so that the upper end of the working box (30) is inserted into the annealing box (501), and the plurality of sealing rods (604) are moved upward and inserted into the corresponding through holes (31) provided in the working box (30), and then the metal material in the working box (30) is heated by the annealing box (501), and in this process, the plurality of sealing rods (604) are continuously moved up and down, and the continuous up and down movement of the plurality of sealing rods (604) will continuously lift up the metal material in the working box (30), so as to prevent the bottom of the metal material from contacting the working box (30) for a long time, thereby preventing the bottom of the metal material from being heated poorly; S3.
