Description

Technical Field

[0001] The utility model relates to the technical field of bracket devices, in particular to a combined coil material rack for an aluminum alloy heat treatment furnace. Background Art

[0002] Heating the metal to a certain temperature in a solid state, maintaining it at this temperature for a certain period of time, and then cooling it to room temperature at a certain cooling rate can change the internal structure and mechanical properties of the metal and alloy materials to meet the requirements of people. This treatment method is called heat treatment, which is a strict and very important production process in the metal processing production process. In the production of aluminum alloy sheet and strip materials, corresponding heat treatment is required to improve and control the final mechanical properties of the sheet and strip materials. In addition, appropriate heat treatment of the intermediate billets is also required during the rolling process to facilitate subsequent processing. The main heat treatment forms of aluminum alloy cold-rolled sheet and strip materials are annealing, quenching and aging.

[0003] Aluminum alloy heat treatment needs to be carried out in a special furnace. During the heat treatment process, the heating of the material mainly relies on the convective heat transfer between the surface of the coil (sheet) and hot air, and the conduction heat transfer inside the coil (sheet) itself. For coils, a material rack is usually required to fix the coils to prevent the aluminum coils from moving during the heat treatment operation.

[0004] At present, the heat treatment material rack for aluminum alloy coils usually uses a frame-type suspended material rack, but this kind of material rack is only suitable for aluminum alloy coils with a steel sleeve in the core (referred to as coiled materials with a barrel). Some aluminum alloy coils without a steel sleeve (referred to as coiled materials without a barrel) need to use other special material racks. This has an adverse impact on production efficiency because the two types of aluminum alloy coils cannot be heat-treated simultaneously and cannot be applied to both types of coils during the production process. Content of the Utility Model

[0005] Aiming at the above deficiencies, the utility model provides a combined coil material rack for an aluminum alloy heat treatment furnace, which can solve the problem that the existing coil material rack cannot be applied to both types of coils at the same time, resulting in troublesome replacement of the material rack and adverse impact on production efficiency.

[0006] To achieve the above object, the utility model adopts the following technical scheme:

[0007] A combined coil material rack for an aluminum alloy heat treatment furnace includes a material rack body. Side rails are arranged upward on both sides of the material rack body, and multiple groups of coiled material with barrel placement grooves for placing coiled materials with a barrel are oppositely arranged on the side rails on both sides; an unbarreled coiled material placement rack for placing unbarreled coiled materials is further arranged at the bottom of the material rack body, and the unbarreled coiled material placement rack is detachably placed on the bottom of the material rack body or the unbarreled coiled material placement rack can also be received into the bottom of the material rack body.

[0008] Further, a limiting groove is formed at the bottom of the rack body;

[0009] When the cylinderless coil material placing rack is detachably placed on the bottom of the rack body, the cylinderless coil material placing rack includes a placing rack body, a limiting block matching the limiting groove is arranged at the bottom of the placing rack body, and a cylinderless coil material placing groove is arranged at the top of the placing rack body.

[0010] Further, placing rack inclined surfaces are arranged on both sides of the top of the placing rack body, the placing rack inclined surfaces are higher outside and lower inside, and the two placing rack inclined surfaces on both sides form the cylinderless coil material placing groove.

[0011] Further, there are a plurality of the limiting grooves, and the plurality of limiting grooves are arranged at the middle position of the bottom of the rack body and distributed longitudinally.

[0012] Further, lifting lugs are arranged at both ends of the cylinderless coil material placing rack.

[0013] Further, a placement groove is formed at the bottom of the rack body;

[0014] When the cylinderless coil material placing rack can be received into the bottom of the rack body, the cylinderless coil material placing rack includes a placing rack body, the placing rack body includes two rotating blocks rotatably arranged at the bottom of the rack body, the two rotating blocks can be placed downward in the placement groove, the two rotating blocks can be turned upward to form the cylinderless coil material placing groove, and when the rotating blocks are turned upward, a wedge block can be embedded between the rotating blocks and the bottom of the rack body to limit the rotating blocks from rotating downward.

[0015] Further, two rotating shafts are arranged in parallel at the middle position of the bottom of the rack body, and the rotating blocks are rotatably installed on the rotating shafts;

[0016] There are a plurality of the cylinderless coil material placing racks, and the plurality of cylinderless coil material placing racks are distributed longitudinally along the bottom of the rack body.

[0017] Further, a clamping groove is formed at the bottom of the rack body, and a clamping block for matching and clamping into the clamping groove is arranged at the bottom of the wedge block.

[0018] Further, a wedge block inclined surface is arranged at the position where the wedge block acts on the rotating block.

[0019] Further, when the rotating block is placed in the placement groove, the rotating block is flush with the bottom of the rack body.

[0020] Compared with the prior art, the beneficial effects of the present utility model are as follows: The present utility model can be compatible and adapted for use with drummed coils or non-drummed coils according to actual needs, and can place drummed coils and non-drummed coils simultaneously. Only one set of combined coil material racks for aluminum alloy heat treatment furnaces is required to be compatible with the placement of drummed coils and non-drummed coils, improving the versatility of the loading of the material racks. At the same time, being able to place drummed coils and non-drummed coils simultaneously helps to improve the full furnace rate of aluminum alloy coil heat treatment and reduce the production cost of coil heat treatment. Since there is no need to replace the material racks according to the coil type, the trouble caused by replacing the material racks can be eliminated, as well as the adverse impact on production efficiency.

[0037] During implementation 1

[0038] Please refer to Figures 1 to 4, this exemplary embodiment provides a combined coil material rack for an aluminum alloy heat treatment furnace. The combined coil material rack includes a rack body 10, and the rack body 10 is integrally welded by profiled steel, having sufficient strength to support the coil. On both sides of the rack body 10, side rails 11 are provided upward. The side rails 11 have a certain height. Similarly, the side rails 11 are welded by profiled steel. On the two side rails 11, a plurality of sets of drum coil placement grooves 12 for placing drum coils are oppositely arranged. Each set of drum coil placement grooves 12 has two, and the two sets of drum coil placement grooves 12 in a group are located on both sides to be able to place the steel sleeves at both ends of the drum coil, ensuring that the drum coil does not roll when placed. In this exemplary embodiment, the drum coil placement groove 12 is formed by two V-shaped plates with openings facing downward. The two V-shaped plates are fixedly welded to the side rail 11 to together form the drum coil placement groove 12.

[0039] At the bottom of the rack body 10, a non-drum coil placement rack 20 for placing non-drum coils is further provided. The non-drum coil placement rack 20 is detachably placed on the bottom of the rack body 10. When in use, the non-drum coil placement rack 20 is placed on the bottom of the rack body 10 to support the non-drum coil and prevent the non-drum coil from rolling. When there is no need to support the non-drum coil, the non-drum coil placement rack 20 can be removed from the bottom of the rack body 10.

[0040] Due to the limited internal space and height of the aluminum alloy heat treatment furnace, the overall height of the rack body 10 cannot be too high. At this time, the side rail 11 cannot be too high. When the drum coil is placed on the drum coil placement groove 12, it will be very close to the bottom of the rack body 10. At this time, it is not suitable to place the non-drum coil placement rack 20 or the non-drum coil placement rack 20 cannot protrude from the bottom surface of the rack body 10. Then, in the use of this utility model, if the drum coil is placed, the non-drum coil placement rack 20 at the corresponding position in the horizontal direction is removed first, and the non-drum coil can be placed at the position where the drum coil is not placed. Exemplarily, please refer to Figures 5 to 7 , Figure 5 In this exemplary embodiment, it is an example where the rack body 10 is all placed with drum coils 40. Figure 6 In this exemplary embodiment, it is an example where the rack body 10 is all placed with non-drum coils 50. Figure 7In this exemplary embodiment, the rack body 10 is an example of placing both the coiled material with a cylinder 40 and the coiled material without a cylinder 50. That is, the combined coiled material rack for an aluminum alloy heat treatment furnace of the present utility model can, according to actual needs, be compatible and adapted for use with the coiled material with a cylinder 40 or the coiled material without a cylinder 50, and can place the coiled material with a cylinder 40 and the coiled material without a cylinder 50 simultaneously. Therefore, only one set of combined coiled material rack for an aluminum alloy heat treatment furnace is needed to be compatible with the placement of the coiled material with a cylinder 40 and the coiled material without a cylinder 50, improving the versatility of the rack loading. At the same time, since it can place the coiled material with a cylinder 40 and the coiled material without a cylinder 50 simultaneously, it helps to increase the full furnace rate of the aluminum alloy coiled material heat treatment and reduce the production cost of the coiled material heat treatment. Because there is no need to replace the rack according to the type of the coiled material, the trouble caused by replacing the rack can be eliminated, as well as the adverse impact on the production efficiency.

[0041] In this exemplary embodiment, a limiting groove 16 is opened at the bottom of the rack body 10. The coiled material rack without a cylinder 20 includes a rack body 21. A limiting block 22 matching the limiting groove 16 is provided at the bottom of the rack body 21, and a coiled material placement groove 23 without a cylinder is provided at the top of the rack body 21. During implementation, the coiled material rack without a cylinder 20 is placed in the limiting groove 16 at the bottom of the rack body 10 by matching the limiting block 22 at the bottom of its rack body 21. At this time, the coiled material rack without a cylinder 20 is stably placed on the bottom of the rack body 10 without moving or shaking, etc. The coiled material placement groove 23 without a cylinder is provided at the top of the rack body 21. During implementation, the coiled material without a cylinder is placed in the placement groove 23, and at this time the coiled material without a cylinder will not roll.

[0042] Placement slopes 24 are provided on both sides of the top of the rack body 21. The placement slopes 24 are higher on the outside and lower on the inside to form a V-shaped structure. The placement slopes 24 on both sides form the coiled material placement groove 23 without a cylinder. The V-shaped coiled material placement groove 23 without a cylinder realizes the side support for the coiled material without a cylinder, ensuring the stable placement of the coiled material without a cylinder without rolling. Lifting lugs 26 are provided at both ends of the coiled material rack without a cylinder 20 to facilitate the staff to move the coiled material rack without a cylinder 20, or to lift the coiled material rack without a cylinder 20 by a crane or the like. In this exemplary embodiment, the lifting lugs 26 are fixedly provided at both ends of the rack body 21. There are multiple limiting grooves 16, and the multiple limiting grooves 16 are opened at the middle position of the bottom of the rack body 10 and are longitudinally distributed. Multiple coiled material racks without a cylinder 20 can be provided, or only one can be provided. The specific number depends on actual usage needs. Multiple coiled material racks without a cylinder 20 can be specifically provided, and the unused coiled material racks without a cylinder 20 can be stored. The multiple limiting grooves 16 are longitudinally distributed in the middle of the bottom of the rack body 10. In actual use, according to the specific placement form (which can be referred to Figures 5 to 7 ), the coiled material rack without a cylinder 20 can be placed in different limiting grooves 16. Of course, it can be understood that if the coiled material without a cylinder is not placed, there is no need to use the coiled material rack without a cylinder 20.

[0043] Example 2

[0044] Different from Example 1, please refer to Figures 8 to 10 , in this exemplary embodiment, the tubeless coil placing rack 20 is in a form that can be received at the bottom of the feeding rack body 10. When the tubeless coil placing rack 20 is used, the tubeless coil placing rack 20 can extend out from the bottom of the feeding rack body 10 to support and place the tubeless coil. When the tubeless coil placing rack 20 is not needed, the tubeless coil placing rack 20 can be received at the bottom of the feeding rack body 10, and at this time, it will not affect the placement of the coiled coil at this position.

[0045] In this exemplary embodiment, an installation groove 13 is opened at the bottom of the feeding rack body 10. The tubeless coil placing rack 20 includes a placing rack body 21. The placing rack body 21 includes two rotating blocks 25 rotatably arranged at the bottom of the feeding rack body 10. The two rotating blocks 25 can be placed downward in the installation groove 13, and the two rotating blocks 25 can also be turned upward to form a tubeless coil placing groove 23. And when the rotating block 25 is turned upward, a wedge block 30 can be embedded between the rotating block 25 and the bottom of the feeding rack body 10 to limit the rotating block 25 from rotating downward. When the rotating block 25 is placed downward in the installation groove 13, it does not affect the placement of the coiled coil at this position. And when the rotating block 25 is turned upward to form the tubeless coil placing groove 23 and the wedge block 30 is embedded, the rotating block 25 is restricted from rotating downward so as to be able to maintain the shape of the tubeless coil placing groove 23, and the specific shape is V-shaped. Thus, the tubeless coil 50 can be placed in the tubeless coil placing groove 23 and cannot roll. At this time, refer to Figure 8 , Figure 9 and Figure 11 . Figure 11 An exemplary implementation diagram of this exemplary embodiment for simultaneously placing coiled coils with tubes and tubeless coils is given. It can be understood that this exemplary embodiment can also place all coiled coils with tubes 40, or all tubeless coils 50, specifically selected according to actual needs. Of course, at the position where the rotating block 25 is placed downward in the installation groove 13, the corresponding coiled coil placing groove 12 for coiled coils with tubes can still place the coiled coil with tubes 40. That is to say, similarly, this exemplary embodiment can be compatible and adapted for use with coiled coils with tubes 40 or tubeless coils 50 according to actual needs, and can simultaneously place the coiled coil with tubes 40 and the tubeless coil 50. Only one set of combined coil material racks for aluminum alloy heat treatment furnaces is needed to be compatible with the placement of coiled coils with tubes 40 and tubeless coils 50, improving the versatility of the rack loading. At the same time, since the coiled coil with tubes 40 and the tubeless coil 50 can be placed simultaneously, it helps to improve the full furnace rate of aluminum alloy coil heat treatment and reduce the production cost of coil heat treatment. Since there is no need to replace the rack according to the coil type, the trouble caused by replacing the rack can be eliminated and the adverse impact on production efficiency can be eliminated.

[0046] Preferably, two rotating shafts 14 are arranged in parallel at the middle position of the bottom of the rack body 10. The rotating blocks 25 are rotatably mounted on the rotating shafts 14, and the rotating blocks 25 on the same side are mounted on the rotating shafts 14 on the same side. There are multiple non-cylindrical coil placing racks 20, and the multiple non-cylindrical coil placing racks 20 are longitudinally distributed along the bottom of the rack body 10. In actual use, the non-cylindrical coil placing racks 20 can be placed in different limiting grooves 16 according to the specific placement form. When the rotating block 25 is placed in the placement groove 13, the rotating block 25 is flush with the bottom of the rack body 10 to ensure that the placement of the cylindrical coil is not affected.

[0047] A clamping groove 15 is formed in the bottom of the rack body 10. A clamping block 31 for matching and clamping into the clamping groove 15 is arranged at the bottom of the wedge block 30. Through the cooperation of the clamping block 31 and the clamping groove 15, when the wedge block 30 is placed at the bottom of the rack body 10 and the rotating block 25 bears the non-cylindrical coil, the wedge block 30 is prevented from shifting horizontally under force, so that the non-cylindrical coil placing groove 23 fails.

[0048] A wedge block inclined surface 32 is arranged at the position where the wedge block 30 acts on the rotating block 25. The wedge block inclined surface 32 abuts against the rotating block 25, so as to increase the contact area and ensure the limiting effect.

[0049] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claimed rights.
