Description

Technical Field

[0001] This utility model relates to a buffer device for the heating cover of an annealing furnace, belonging to the technical field of buffer equipment for annealing furnaces in the cold rolling industry. Background Technology

[0002] In the cold rolling process, stress relief of sheet metal is inseparable from the annealing unit, of which the heating hood is a crucial component for annealing heating. Installed on the furnace platform, the heating hood's safe operation is a prerequisite for ensuring efficient equipment operation. Considering maintenance costs, the overall weight of a typical heating hood is around 3 tons, making it quite heavy. When loaded into the furnace, the heating hood exerts a significant impact on the furnace platform. Traditional shock absorption methods use rigid supports, which are relatively simple. However, during the installation of the heating hood, vertical impacts cause hard damage to the furnace platform and the surrounding ground, failing to achieve the intended shock absorption. Utility Model Content

[0003] The purpose of this invention is to provide a buffer device for the heating hood of an annealing furnace, which can effectively prevent the heating hood from impacting the furnace platform during loading, avoid damage to the furnace platform due to instantaneous high pressure, and solve the problems existing in the background art.

[0004] The technical solution of this utility model is:

[0005] An annealing furnace heating hood buffer device includes a heating hood, a furnace platform, a support, and a buffer mechanism. The support is annular and fits with the heating hood. The support is fixed to the lower part of the heating hood. Several buffer mechanisms are evenly arranged in the circumferential direction of the support. Each buffer mechanism includes connecting bolts, connecting plates, pressure plates, springs, and a base plate. The connecting plates are fixedly connected to the support by connecting bolts, the pressure plates are fixed to the connecting plates, and the springs are arranged between the pressure plates and the base plate.

[0006] The bracket has a U-shaped cross-section, and bolt holes for connecting bolts are provided on the bracket and the connecting plate.

[0007] The bolt holes on the connecting plate that mate with the connecting bolts are elongated.

[0008] The connecting plate and the pressure plate are arranged vertically, and a stiffening plate is provided between the connecting plate and the pressure plate.

[0009] The upper end of the spring is fixedly connected to the pressure plate, and the lower end of the spring is fixedly connected to the base plate.

[0010] The buffer mechanism is evenly distributed along the circumference of the support, consisting of four oppositely arranged components.

[0011] The beneficial effects of this utility model are: it can effectively prevent the heating cover from impacting the furnace platform when loading the furnace, and avoid damage to the furnace platform due to the instantaneous large pressure. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings and examples.

[0016] See attached document Figure 1 , 2 An annealing furnace heating cover buffer device includes a heating cover 1, a furnace platform 2, a support 3, and a buffer mechanism. The support 3 is annular and cooperates with the heating cover 1. The support 3 is fixed to the lower part of the heating cover 1. Several buffer mechanisms are evenly arranged in the circumferential direction of the support 3. The buffer mechanism includes a connecting bolt 4, a connecting plate 5, a pressure plate 7, a spring 8, and a base plate 9. The connecting plate 5 is fixedly connected to the support 3 by the connecting bolt 4. The pressure plate 7 is fixed to the connecting plate 5. The spring 8 is arranged between the pressure plate 7 and the base plate 9.

[0017] In this embodiment, refer to the appendix Figure 1 , 2 The cross-section of the support 3 is U-shaped, and four buffer mechanisms are evenly arranged in the circumferential direction of the support 3.

[0018] The bracket 3 and the connecting plate 5 are respectively provided with bolt holes that mate with the connecting bolts 4, wherein the bolt holes on the connecting plate 5 are elongated.

[0019] The connecting plate 5 and the pressure plate 7 are arranged vertically, and a stiffening plate 6 is provided between the connecting plate 5 and the pressure plate 7. The upper end of the spring 8 is fixedly connected to the pressure plate 7, and the lower end of the spring 8 is fixedly connected to the base plate 9.

[0020] During installation, first weld bracket 3 to heating cover 1, and then evenly install four sets of buffer mechanisms on bracket 3.

[0021] During the process of the heating cover 1 falling onto the furnace platform 2, the four sets of buffer mechanisms set on the support 3 can effectively prevent the heating cover 1 from impacting the furnace platform 2 when loading the furnace, thus avoiding damage to the furnace platform 2 due to the large pressure it is subjected to at any moment.

[0022] Once the heating cover 1 has successfully landed on the furnace platform 2, loosen the connecting bolts 4, remove the buffer mechanism, and move it to another heating cover 1 to be used.
