Description

Technical Field

[0001] The utility model relates to the technical field of heat treatment tools for aluminum alloy coils, in particular to an integrated suspended rack for a heat treatment furnace of aluminum alloy coils. Background Art

[0002] Heating a 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, corresponding heat treatment is required to improve and control the final mechanical properties of the sheet and strip. In addition, appropriate heat treatment of the intermediate billet is also required during the rolling process to facilitate subsequent processing. The main heat treatment forms of aluminum alloy cold-rolled sheet and strip are annealing, quenching and aging. 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 rack is usually required to relatively fix the coils to prevent them from moving during the heat treatment operation.

[0003] At present, the suspended rack for heat treatment of aluminum alloy coils is usually a frame-type suspended rack. According to the volume of the furnace body, multiple coils can be placed on one rack, but the number of aluminum coils placed on the same rack is fixed and cannot be adjusted according to the diameter of the coils, which wastes space and reduces production efficiency. Summary of the Utility Model

[0004] In order to overcome at least one of the above-mentioned defects of the prior art, the utility model provides an integrated suspended rack for a heat treatment furnace of aluminum alloy coils, so as to solve the problems such as the number of coils placed on one rack cannot be adjusted according to the diameter of the coils.

[0005] The technical solution adopted by the utility model to solve its problems is as follows:

[0006] An integrated suspended rack for a heat treatment furnace of aluminum alloy coils, including a rack, the rack includes a bottom frame and two support frames, the two support frames are respectively arranged on both sides of the bottom frame, support rods are arranged on both support frames, the two support rods are used to support a fixed seat, a through hole is arranged on the fixed seat, a first limiting edge is arranged on the support rod, a number of uniformly arranged first fixing holes are arranged on the first limiting edge, a fixing rod is slidably connected in the first fixing hole, and the fixing rod is slidably connected with the through hole.

[0007] With the above solution, the fixed seat is used to place the coil material. By providing a plurality of evenly arranged first fixing holes on the first limiting edge, the position of the fixing rod can be adjusted according to aluminum coil materials of different sizes. In this way, it can adapt to coils of various specifications, improving the versatility and flexibility of the equipment. It can also adjust the number of coils placed on the rack according to coils of different specifications, making better use of the space.

[0008] Furthermore, a cross bar is provided at one end of each of the two support rods. A second limiting edge is provided on the cross bar. A sliding rod is slidably connected to the support frame. A third limiting edge is provided on the sliding rod. The cross bar and the sliding rod are used to support the fixed seat.

[0009] With the above further solution, by providing the sliding rod on the support frame and the third limiting edge thereon, the position of the sliding rod can be adjusted according to actual needs to match aluminum coil materials of different width specifications. In this way, the rack has better adaptability, is suitable for various product sizes, and can, by cooperating with the support rods, make the coils of different specifications have a more reasonable placement, thus making better use of the space.

[0010] Furthermore, a number of evenly arranged second fixing holes are provided on the second limiting edge. A number of evenly arranged third fixing holes are provided on the third limiting edge. The positions of the second fixing holes correspond to the positions of the third fixing holes. A fixing rod is slidably connected in the second fixing holes and the third fixing holes.

[0011] With the above further solution, the fixing rod can fix the fixed seat.

[0012] Furthermore, slide rails are provided below each of the two support rods. Slide heads are provided at both ends of the sliding rod. The slide heads are slidably connected in the slide rails.

[0013] With the above further solution, the cooperation of the slide rails and the slide heads enables the sliding rod to easily move along the direction of the support rod. The slide rails provide a guiding and supporting function for the sliding rod, ensuring its stable movement in the horizontal direction without deviation, and can also increase the load-bearing capacity of the sliding rod.

[0014] Furthermore, snap edges are provided on opposite sides of each of the two support rods. Clasps are provided on the upper sides of both ends of the sliding rod. The clasps are snap-fitted with the snap edges.

[0015] With the above further solution, the cooperation of the clasps and the snap edges provides an additional locking mechanism to ensure that the sliding rod is firmly fixed in the required position. This design reduces the risk of accidental movement of the sliding rod during use, thereby improving the structural stability and safety of the entire rack. Through the simple snap-fitting operation of the clasps and the snap edges, the sliding rod can be quickly positioned and fixed in place without complex tools or fasteners, which greatly simplifies the installation process, saves operation time, and improves work efficiency.

[0016] Further, a fixing cylinder is also slidably connected to the cross bar and the sliding rod. The fixing cylinder is slidably connected in the second fixing hole and the third fixing hole. Two symmetrically arranged clamping mechanisms are provided at one end of the fixing cylinder, and a compression cap is threadedly connected to the outer side of the other end. A squeezing rod is slidably connected in the fixing cylinder, and a pressing ring is also threadedly connected to the end of the fixing cylinder connected with the compression cap.

[0017] Through the above further solution, the clamping mechanism can provide a limiting point for one end of the fixing cylinder. The compression cap can squeeze the squeezing rod, and through the pressing rod, the clamping mechanism is squeezed, and then through the pressing ring, so that the sliding rod, the fixing seat and the cross bar are fixedly connected through the fixing cylinder, improving the stability of the overall structure.

[0018] Further, the clamping mechanism includes a clamping rod and a spring. Two symmetrically arranged sliding holes are provided at the end of the fixing cylinder. Hidden grooves are provided on the outer side of the fixing cylinder at the positions of the two sliding holes. The clamping rod is slidably connected in the sliding hole. A hidden plate is provided at one end of the clamping rod located outside the fixing cylinder, and a limiting resistance platform is provided at the other end. The hidden plate is located in the hidden groove. The spring is sleeved on the clamping rod, with one end abutted against the limiting resistance platform and the other end abutted against the inner side of the fixing cylinder.

[0019] Through the above further solution, when the fixing cylinder is inserted into the third fixing hole of the sliding rod, the clamping rod is squeezed by the squeezing rod, so that the hidden plate of the clamping rod is extruded from the hidden groove, and thus a limiting point can be provided. Then, it is squeezed through the pressing ring. This design provides an automatic locking function, ensuring the stable connection of the sliding rod, the fixing seat and the cross bar without additional operation.

[0020] Further, a sliding inclined surface is provided at the end of the clamping rod provided with the limiting resistance platform, and two symmetrically arranged sliding surfaces are provided at the end of the squeezing rod facing the clamping rod. The sliding surfaces are slidably connected with the sliding inclined surface.

[0021] Through the above further solution, the combined design of the sliding inclined surface and the sliding surface enables the squeezing rod to slide smoothly during the pushing process, reducing the resistance during operation. This not only improves the comfort of operation, but also ensures the coherence and stability of the action, and can better squeeze the clamping rod.

[0022] In summary, an integrated suspended material rack for an aluminum alloy coil heat treatment furnace provided by the present utility model has the following technical effects:

[0023] 1. Through multiple locking mechanisms such as the slide rail, the clamping eaves and the buckle, the clamping mechanism and the pressing ring, the stability of the sliding rod is ensured, and the risk of loosening caused by vibration or external force is reduced.

[0024] 2. By providing a plurality of uniformly arranged first fixing holes on the first limiting edge, the position of the fixing rod can be adjusted according to aluminum coils of different sizes, so that it can adapt to coils of various specifications, improving the versatility and flexibility of the equipment. Moreover, the number of coils placed on the rack can be adjusted according to coils of different specifications, making better use of the space.

[0025] 3. By means of the sliding rod and the cross bar, the position of the sliding rod can be adjusted according to actual needs to match aluminum coils of different width specifications, making the rack have better adaptability and being applicable to various product sizes. By cooperating with the supporting rod, coils of different specifications can be placed more reasonably, thus making better use of the space. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] Reference Figure 4 As shown in the figure, slide rails 22 are provided below both support rods 2. Slide heads 62 are provided at both ends of the sliding rod 6. The slide heads 62 are slidably connected in the slide rails 22.

By squeezing the clamping mechanism 8 through the push rod and then through the compression ring 73, the sliding rod 6, the fixing seat 3 and the cross bar 5 are fixedly connected through the fixing cylinder 7, improving the stability of the overall structure.

[0047] Among them, the clamping mechanism 8 includes a clamping rod 81 and a spring 82. Two symmetrically arranged sliding holes 74 are provided at the end of the fixing cylinder 7.

[0049] The working principle of the present utility model is as follows:

[0050] First, calculate how to place according to the size of the rack 1 and the size of the coil. The coil is placed on the fixed seat 3;

[0051] When the fixed seat 3 needs to be placed on the two support rods 2, the through hole 31 on the fixed seat 3 corresponds to the first fixing hole 211. The fixing rod 4 passes through the first fixing hole 211 on the first limiting edge 21 on one side and enters the through hole 31 on the fixed seat 3. The fixing rod 4 passes through the first fixing hole 211 on the first limiting edge 21 on the other side and enters the through hole 31 on the fixed seat 3 to fix the fixed seat 3;

[0052] When the fixed seat 3 needs to be placed on the slide rod 6 and the cross bar 5, slide the skateboard to a predetermined position so that the through hole 31 on the fixed seat 3 corresponds to the second fixing hole 511 and the third fixing hole 611. The fixing rod 4 passes through the second fixing hole 511 on the second limiting edge 51 and enters the through hole 31 on the fixed seat 3 to fix the fixed seat 3. The fixing rod 4 passes through the third fixing hole 611 on the third limiting edge 61 and enters the through hole 31 on the fixed seat 3 to fix the fixed seat 3;

[0053] The fixing cylinder 7 passes through the second fixing hole 511 on the second limiting edge 51, the through hole 31 on the fixed seat 3, and the third fixing hole 611 on the third limiting edge 61. Twist the compression cap 71, so that the extrusion rod 72 can be moved to the other end. The sliding surface 721 on the extrusion rod 72 is slidably connected with the sliding inclined surface 813 on the clamping rod 81. Thus, the extrusion rod 72 can extrude the clamping rod 81, and the clamping rod 81 moves outward, so that the hidden plate 811 is extruded from the hidden groove 75, and then a limiting point can be provided. Pull the fixing cylinder 7 to make the hidden plate 811 abut against the second limiting edge 51, and twist the compression ring 73 to make the compression ring 73 abut against the third limiting edge 61. Thus, the slide rod 6 can extrude the fixed seat 3 to stably fix the fixed seat 3;

[0054] When the fixing cylinder 7 needs to be disassembled, just twist the compression cap 71, move the clamping rod 81 inward through the spring 82, make the hidden plate 811 located in the hidden groove 75, and pull out the fixing cylinder 7, and then the disassembly can be completed. The disassembly is convenient.

Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered by the protection scope of the present utility model.
