Description
Technical Field
[0001] The invention relates to the technical field of metal processing, in particular to an annealing furnace for copper tube production. Background Art
[0002] Annealing furnaces are used in the production of copper tubes. The main purpose of using annealing furnaces is to eliminate the internal stress generated by the copper tubes during the processing process through heating and insulation, improve their organizational structure, and thus enhance their mechanical properties and plasticity.
[0003] The existing copper tubes are uniformly placed in a groove and then heated. This will cause the copper tubes to be squeezed by the gravity between the copper tubes at high temperature, resulting in uneven heating of the copper tubes, and easily causing deformation or cracks of the copper tubes. The outer wall is easily oxidized at high temperatures. If there is dirt on the outer wall or inner wall of the copper tube before processing, the metal residue will adhere to the copper tube at high temperature, making the copper tube quality substandard. If the heated copper tube is taken out and placed without use, the outer wall of the copper tube will rust, affecting the later use.

[0015] Compared with the prior art, the present invention provides an annealing furnace for copper tube production, which has the following beneficial effects: 1.

[0024] In this embodiment, the auxiliary mechanism 6 includes four groups of fixed blocks 62 fixedly connected to the annealing furnace body 1, and the adjacent sides of the four groups of fixed blocks 62 are commonly fixedly connected to the inner gear ring 61. A plurality of groups of gears 63 are evenly arranged on the inner side of the inner gear ring 61, and the outer sides of the plurality of groups of gears 63 are meshed with the inner side of the inner gear ring 61.

[0025] Specifically, the fixing block 62 allows the inner gear ring 61 to be installed in the annealing furnace body 1. The inner gear ring 61 cooperates with the gear 63 to allow the gear 63 to rotate on its own while rotating together. The cross bracket 64 fits with the slot 13 through the card slot 65, so that the copper tube body 7 can be installed on the upper end of the cross bracket 64 and rotate on its own while rotating together with the gear 63, thereby promoting a uniform heating effect.
[0026] In this embodiment, a fixed shaft 66 is rotatably connected to the inner side of the slot 65 near the middle, and four groups of scrapers 614 are fixedly connected above the cross bracket 64 outside the fixed shaft 66, and the sides of the scrapers 614 away from each other are in contact with the inner wall of the copper tube body 7.
[0027] Specifically, the fixed rotating shaft 66 is a cross bracket 64 and four groups of scrapers 614 for fixing the position. The scrapers 614 can also stabilize the position of the copper tube body 7 and clean the inner wall of the copper tube body 7.

[0030] In this embodiment, two groups of symmetrical first limit blocks 611 are fixedly connected below the outer placement plate 67 of the fixed rotating shaft 66, and two groups of symmetrical second limit blocks 612 are arranged at the upper ends of the two groups of first limit blocks 611. The second limit blocks 612 are F-shaped, and the adjacent sides of the two groups of second limit blocks 612 are fixedly connected with wire brushes 617, and the inner walls of the two groups of second limit blocks 612 are in contact with the upper and lower ends of the gear 63.
[0031] Specifically, the first limit block 611 is used to limit and install the position of the second limit block 612. The second limit block 612 is F-shaped and is used to stabilize the position of the gear 63. When the gear 63 rotates, it rubs with the wire brush 617 for cleaning to prevent dirt on the top from affecting the movement of the gear 63.
[0032] In this embodiment, the upper ends of the two groups of second limit blocks 612 are fixedly connected with two groups of symmetrical limit rods 613, and the adjacent sides of the two groups of limit rods 613 are fixedly connected with flat brushes 616, and the adjacent sides of the two groups of limit rods 613 are in contact with the outer wall of the copper tube body 7.

[0035] Specifically, the blades 12 are rotated by the airflow generated by the exhaust fan 57 , and when the spray head 11 outputs the graphite lubricant, the blades 12 are used to break up the graphite lubricant and evenly sprinkle it on the outer wall of the copper tube body 7 when the copper tube body 7 revolves.
[0036] In this embodiment, the anti-rust mechanism 16 includes a mounting bracket 161 fixedly connected to the pipe port 2, a guide groove 1614 is fixedly connected to the inner side of the mounting bracket 161 near the middle position, two groups of symmetrical anti-rust paint boxes 162 are fixedly connected to the inner wall of the mounting bracket 161 through the bracket, a partition 163 is fixedly connected to the inner side of the anti-rust paint box 162, a discharge pipe 164 is slidably connected to the inner side of the anti-rust paint box 162, the discharge pipe 164 passes through the partition 163, the upper end of the discharge pipe 164 is fixedly connected to a limiting plate 165, a feed port 166 is provided on the outer side of the discharge pipe 164, a first spring 167 is arranged on the outer side of the discharge pipe 164, the upper end of the first spring 167 is fixedly connected to the partition 163, the lower end of the first spring 167 is fixedly connected to the discharge pipe 164, and a discharge port 169 is fixedly connected to the outer side of the discharge pipe 164 near the lower end.
[0037] Specifically, the copper tube body 7 is pushed by the upward force from the bottom, so that the first pressure plate 1610 drives the discharge pipe 164 to slide into the anti-rust paint box 162, so that the feed port 166 passes through the partition 163, and the anti-rust paint in the anti-rust paint box 162 is input into the discharge pipe 164 through the feed port 166, and then output through the discharge port 169. When the second pressure plate 1612 rotates, the discharge port 169 is in a vertical state, and the discharge port 169 can be staggered with the second pressure plate 1612 through the slot 1613, and then the outer wall of the copper tube body 7 is sprayed. After the copper tube body 7 is detached, the second pressure plate 1612 is vertically reset by the second spring 168, and the discharge pipe 164 is reset by the first spring 167. The limit plate 165 is limited to prevent the discharge pipe 164 from detaching.
[0038] In this embodiment, the lower end of the discharge pipe 164 is fixedly connected to the first pressure plate 1610, the lower end of the first pressure plate 1610 is rotatably connected to the hinge 1611, the upper end of the other leaf of the hinge 1611 is fixedly connected to the second pressure plate 1612, the outer side of the second pressure plate 1612 is provided with a slot 1613, the upper end of the slot 1613 is fixedly connected to the second spring 168, the upper end of the second spring 168 is fixedly connected to the discharge pipe 164, the edge above the end where the first pressure plate 1610 and the second pressure plate 1612 are close to each other is designed as an arc surface, and the ends where the two groups of second pressure plates 1612 are close to each other are fixedly connected to a rubber pad 1615.
[0039] Specifically, the copper tube body 7 is placed in the annealing furnace body 1 and passes through the guide groove 1614. The lower end of the copper tube body 7 presses the second pressing plate 1612. The second pressing plate 1612 rotates through the hinge 1611 to stagger the copper tube body 7, and then is reset by the second spring 168. After the annealing is completed, the copper tube body 7 is aligned with the guide groove 1614 and taken out by the mechanical wall. The upper end of the copper tube body 7 touches the second pressing plate 1612. The second pressing plate 1612 is rotated upward by the hinge 1611 through the design of the arc edge, and then is blocked by the copper tube body 7 when it moves upward and cannot be reset. It is pushed by the copper tube body 7 from the bottom to the top, so that the first pressing plate 1610 drives the discharge pipe 164 to slide into the anti-rust paint box 162. The rubber pad 1615 can generate a large friction force on the copper tube body 7 and avoid scratches.
[0040] Working principle: when in use, after opening the pipe port 2, the copper tube body 7 is placed into the annealing furnace body 1 by using an industrial robot arm, and passes through the guide groove 1614. The lower end of the copper tube body 7 presses the second pressing plate 1612, and the second pressing plate 1612 rotates through the hinge 1611 to stagger the copper tube body 7, and then resets through the second spring 168. The inner wall of the copper tube body 7 passes through the fixed rotating shaft 66 and fits with the scraper 614. Then the lower end of the copper tube body 7 fits with the card slot 65 through the slot 13 to complete the placement. The heating tube 68 is started for heating, and then the motor 10 is started to rotate the placement plate 67. The M-shaped design of the placement plate 67 enables the gear 63 with eight fulcrums to rotate through the fixed rotating shaft 66 and the cross bracket 64, and the gear 63 is driven to rotate while the copper tube body 7 is driven to rotate by itself through the inner gear ring 61. Open the pneumatic valve connecting the argon tank 56 with the first gas pipe 52 and the second gas pipe 54, so that the argon gas is output to the annealing furnace body 1 through the exhaust pipe 53 and the exhaust pipe 55. In order to prevent copper from oxidizing at high temperature, argon gas is used as a protective gas to create a controlled atmosphere. After the delivery is completed, close the pneumatic valve connecting the argon tank 56 with the first gas pipe 52 and the second gas pipe 54; Start the hot air box 51 to generate hot air flow, then open the pneumatic valve connected to the exhaust pipe 53 and the exhaust pipe 55, start the exhaust fan 58 to input the hot air flow from the bottom to the annealing furnace body 1, start the exhaust fan 57 to recover the heat accumulated above to the hot air box 51 and output it again, forming a thermal cycle, accelerating the temperature rise, and stabilizing the heat inside the annealing furnace body 1 to avoid uneven heating of the copper tube body 7, start the spray head 11 to output the graphite lubricant in the graphite lubricant box 3, and the blade 12 rotates under the influence of the air flow of the exhaust pipe 53, evenly scatters the liquid output by the spray head 11, and sprinkles it on the outer wall of the rotating copper tube body 7. When the copper tube body 7 rotates, the fixed shaft 66 will only revolve through the inner gear ring 61, and then the scraper 614 is used to scrape the copper tube body 7. The inside of the tube body 7 is cleaned to avoid missing metal debris, and the copper tube body 7 is supported during annealing to avoid bending or separation caused by high temperature and rotation. The fixed shaft 66 is connected to the second limit block 612 through the first limit block 611 to clamp the gear 63, and then the gear 63 is polished by the wire brush 617 to prevent the debris falling from the inner wall or outer wall of the copper tube body 7 from affecting the movement of the gear 63, and then cleaned. The upper end of the second limit block 612 drives the limit rod 613 to clamp the outer wall of the copper tube body 7, and the outer wall of the copper tube body 7 is cleaned by the flat brush 616, and evenly covered with graphite lubricant. The liquid and debris falling from the inner and outer walls of the copper tube body 7 fall on the upper end of the bottom plate 615 through the gap between the gear 63 and the cross bracket 64; The output shaft of the motor 10 drives four groups of cleaning rods 69 to clean the debris and liquid on the upper end of the bottom plate 615. The arc surface design of the bottom plate 615 facilitates the debris and liquid to slide down. Then, the bevel design of the cleaning rods 69 can continuously push the dirt downward during rotation and concentrate it in the gap between the annealing furnace body 1 and the base 4. Then, the cleaning block 610 rotates in the gap, and the liquid passes through the filter screen 14 and is concentrated in the first recovery tank 8, while the solid dirt is concentrated in the second recovery tank 9. After annealing is completed, the argon tank 56 is empty, the pneumatic valve connecting the hot air box 51, the exhaust pipe 53 and the exhaust pipe 55 is closed, the pneumatic valves of the first gas supply pipe 52 and the second gas supply pipe 54 are opened, and then the input port of the argon tank 56 is opened, and the exhaust fan 57 and the exhaust pipe 55 are started so that the hot air flow of the annealing furnace body 1 can be output to the outside through the argon tank 56 for ventilation, so that the temperature in the annealing furnace body 1 is quickly reduced, and then the pipeline port 2 is opened, and the copper tube body 7 is aligned with the guide groove 1614 and taken out by the mechanical wall. The upper end of the copper tube body 7 touches the second pressing plate 1612, and the second pressing plate 1612 is rotated upward by the hinge 1611 through the design of the curved edge, and then is blocked by the copper tube body 7 when it moves upward and cannot be reset, and is pushed from the bottom to the top by the copper tube body 7, and the rubber pad 16 15 can generate greater friction on the copper tube body 7 and avoid scratches, so that the first pressing plate 1610 drives the discharge pipe 164 to slide into the anti-rust paint box 162, so that the feed port 166 passes through the partition 163, and the anti-rust paint in the anti-rust paint box 162 is input into the discharge pipe 164 through the feed port 166, and then output through the discharge port 169. When the second pressing plate 1612 rotates, the discharge port 169 is in a vertical state, and the discharge port 169 can be staggered by the second pressing plate 1612 through the slot 1613, and then the outer wall of the copper tube body 7 is sprayed. After the copper tube body 7 is detached, the second pressing plate 1612 is vertically reset by the second spring 168, and the discharge pipe 164 is reset by the first spring 167. The limit plate 165 prevents the discharge pipe 164 from detaching and limits it.
