Description

Technical Field

[0001] The utility model belongs to the technical field of forging equipment, and particularly relates to a detachable heat-insulating cover for a clamping wall hanger for preventing a forging blank from cooling before a forging and rolling process. Background Art

[0002] At present, in the forging industry, the forging and rolling forming process of large cylindrical forgings mostly adopts the method of crane with wall clamp to clamp the forging billet or forging out of the furnace. The whole operation process requires skilled crane operators to operate, the purpose is to transfer the forging billet to the hydraulic press or ring rolling machine and other equipment as soon as possible for forging and rolling forming process. The length of the transfer process will greatly affect the surface temperature of the forging billet, especially when forging large annular and cylindrical forgings made of stainless steel or titanium alloy, the billet itself has a large volume, and the heat loss on the outer surface is the most serious, causing the outer surface temperature to drop quickly, resulting in the maximum temperature difference between the inside and outside reaching 150~200℃. When the surface temperature of the billet drops a lot and the temperature difference between the inside and outside is large, the forging and rolling forming process is easy to cause cracks on the surface, and even the deformation resistance of the material increases sharply due to the temperature drop during the ring rolling process, resulting in the situation of forging and rolling motion, which cannot meet the process requirements and seriously affects the quality of forging and rolling. After the above situation occurs, it is usually necessary to clean the forging or return to the furnace for reheating, which will greatly reduce production efficiency and increase the production cost of the enterprise.

[0003] Therefore, in order to avoid the phenomenon of surface cooling of forgings due to the long time of the clamping wall hanger being out of the furnace during the forging and rolling process, it is necessary to design an anti-cooling measure to reduce the heat loss on the surface of the forgings so that the subsequent forging and rolling process can meet the process quality requirements, thereby improving production efficiency and reducing enterprise losses.

DETAILED DESCRIPTION

[0033] In order to enable those skilled in the art to better understand the present invention, the present invention is now further described in conjunction with specific implementation methods.

[0034] Embodiment 1:

[0035] like Figure 1~Figure 4As shown, the utility model provides a detachable heat preservation cover for a clamping wall hanger, comprising two symmetrically arranged sub-cover bodies. When used, the two sub-cover bodies are arranged on the clamping wall hanger 5 and are symmetrically arranged about the axis center of the cylindrical forging blank 6. Figure 2 , Figure 3 and Figure 4 shown.

[0036] like Figure 1-Figure 4 As shown, the sub-hood body includes a bottom frame 1, a connecting frame 2, and a heat-insulating curtain 3.

[0037] The bottom frame 1 is horizontally arranged, and includes an arc-shaped side frame 11 and a sealing side frame 12 connected to both ends of the arc-shaped side frame 11; Figure 2 A plurality of parallel reinforcing ribs 13 are provided between the arcuate side frame 11 and the sealing side frame 12 , and two ends of the reinforcing ribs 13 are respectively connected to the arcuate side frame 11 and the sealing side frame 12 to improve the overall rigidity and stability of the bottom frame 1 .

[0038] The connecting frame 2 is arranged above the bottom frame 1, and its bottom end is connected to the bottom frame 1, and the top end is connected to the wall hanger 5; specifically, the connecting frame 2 includes a post plate 21, a load-bearing plate 22, and a suspension rod 23 which are connected in sequence from top to bottom in the vertical direction, wherein a plurality of post plates 21 and a suspension rod 23 are provided to ensure that they are stably connected to the wall hanger 5; the post plate 21 and the wall hanger 5 are detachably connected by bolts, the bottom end of the suspension rod 23 is welded to the sealing side frame 12, the post plate 21 is welded above the load-bearing plate 22, and the suspension rod 23 is welded below the load-bearing plate 22.

[0039] The thermal insulation curtain 3 includes a cover curtain 31 and side curtains 32 provided with a thermal insulation cotton layer. The cover curtain 31 is laid on the bottom frame 1 and is closed at the top to reduce the heat lost through the top. The side curtains 32 are vertically arranged below the bottom frame 1 to wrap the surrounding side walls of the tubular forging blank 6 to reduce the heat lost through the sides, so that the tubular forging blank 6 just out of the furnace is wrapped inside the thermal insulation curtain 3 to avoid the surface temperature of the forging blank dropping too quickly due to the heat loss in the air. The top of the side curtain 32 is detachably connected to the arc-shaped side frame 11 to facilitate the installation, disassembly and replacement of the side curtain 32.

[0040] Furthermore, the length of the side curtain 32 is adapted to the height of the cylindrical forging blank 6 , that is, the length of the side curtain 32 is adjusted at any time according to the height of the cylindrical forging blank 6 , so that the side curtain 32 can wrap the cylindrical forging blank 6 to the greatest extent.

[0041] The sub-cover body is also provided with a plurality of reinforcing rods 4, one end of the reinforcing rod 4 is connected to the reinforcing rib 13, and the other end is connected to the suspension rod 23 of the connecting frame 2; the inclination angle between the reinforcing rod 4 and the horizontal plane is an acute angle, that is, the reinforcing rod 4, the suspension rod 23, and the reinforcing rib 13 form a stable triangular connection area, thereby improving the connection stability between the bottom frame 1 and the connecting frame 2.

[0042] The arc side frame 11, the sealing side frame 12, the reinforcing ribs 13, the reinforcing rods 4, and the suspension rods 23 are all square steel pipes made of lightweight steel. The plate 21, the load-bearing plate 22, and the suspension rods 23 are also made of lightweight steel, which reduces the weight of the frame while ensuring the overall rigidity of the frame, thereby reducing the energy consumption required for lifting.

[0043] During specific use, first fix the plate 21 with bolts and nuts to install the two sub-cover bodies on both sides of the wall hanger 5. After the connecting frame 2 and the bottom frame 1 are fixed, connect the side curtains 32 of the thermal insulation curtain 3 to the arc-shaped side frame 11 and determine the sagging length of the side curtains 32 according to the height of the tubular forging billet 6; then hang the wall hanger 5 on the crane hook, transfer the entire wall hanger 5 and the thermal insulation cover to the top of the tubular forging billet 6, and the crane hook drops to complete the clamping of the tubular forging billet 6; after the wall hanger 5 clamps the tubular forging billet 6, the crane hook lifts and transfers the tubular forging billet 6 to other equipment for forging and rolling process.

[0044] The length of the side curtain 32 is slightly greater than the height of the tubular forging blank 6, so that the thermal insulation curtain 3 can completely wrap the tubular forging blank 6. The heat on the outer surface of the tubular forging blank 6 will overflow upward, and the cover curtain 31 on the top will block the heat overflowing upward, thereby forming a good thermal insulation effect and reducing heat loss.

[0045] After the forging production process is completed, the two sub-cover bodies of the insulation cover can be separated from the wall-clamping hanger 5 as a whole by removing the bolts and nuts fixed to the plate 21. The operation is simple and convenient, and does not affect the production of other products by the wall-clamping hanger 5.

[0046] To sum up, the detachable thermal insulation cover for the wall hanger provided by the utility model can effectively reduce the heat loss on the surface of the forging billet during the transfer process of the forging billet out of the furnace, avoid a large temperature difference between the inside and outside of the forging billet, thereby ensuring the quality of the billet in the subsequent forging and rolling process, avoiding the forging cleaning or reheating process due to quality problems, improving the production forging efficiency and reducing production costs.

[0047] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent changes and modifications made within the scope of the present invention should still fall within the scope of the present invention.
