Description

Technical Field

[0001] The utility model relates to the technical field of metal processing equipment, and particularly relates to a buffer device for steel billet heads. Background Art

[0002] When rolling large-sized rectangular steel, a flame cutting machine is needed to cut the head and tail. The head of the billet falls from the second-floor platform 4 meters high into the scrap steel hopper through a chute. Due to the large weight of the head and the large potential energy when falling from a high place, it causes a very large impact on the scrap steel hopper, resulting in problems such as bulging and welding detachment of the scrap steel hopper. In order to improve the service life of the scrap steel hopper, the current technical solution in this field is to reduce the falling potential energy of the head by adding a buffer component in the chute. When the flame cutting machine cuts off the head, the head enters the chute through the feed port. After the buffer component in the chute offsets part of the potential energy of the head, the potential energy is significantly weakened when the head is discharged into the scrap steel hopper through the discharge port, thereby reducing the impact on the scrap steel hopper.

[0003] However, the applicant found that: when the flame cutting machine cuts steel, in addition to generating the potential energy of the head, a large amount of cutting slag and granulated water are also generated, which flow into the scrap steel hopper along the chute together. The cutting slag affects the purity of the scrap steel and needs to be processed offline later. Drainage holes are opened at the bottom of the scrap steel hopper, and the water with the cutting slag flows to the ground, often blocking the ground drainage trough. After a long time, it will also become caked. Only during the production shutdown time, a large amount of manpower is spent cleaning the cutting slag and the fallen heads on the ground, so the workload of manual operation is increased. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0035] Please refer to Figures 1-5 , the present utility model provides a technical solution: a billet head buffer device, including a chute 1 provided with a feed inlet and a discharge outlet. The chute 1 has a vertical chute arranged vertically and an inclined chute arranged obliquely;

[0036] As Figure 1 shown, the buffer device further includes: a first buffer member provided near the discharge outlet in the inclined chute. The first buffer member is used to reduce the falling potential energy of the billet head entering the inclined chute. In the non-working state, the first buffer member blocks the discharge outlet; in this embodiment, the first buffer member includes: a flap 4 and a fixing member that rotatably arranges the flap 4 in the inclined chute. The flap 4 fits with the inner wall of the inclined chute; specifically, the fixing member includes: a support plate 3 provided at the upper end of the inclined chute; an end shaft 15 connected to the flap 4, and the end shaft 15 is rotationally matched with a rotating groove 17 opened in the support plate 3, preferably connected by a bearing;

[0037] As Figure 3 shown, the buffer device further includes: an inclined hole 20 opened in the inclined chute and in front of the first buffer member; a collection assembly for temporarily storing cutting slag and granulated water, and the collection assembly is connected to the inclined hole 20; in this embodiment, the collection assembly includes: a water receiving tank 5 provided at the bottom end of the inclined chute, and the water receiving tank 5 is connected to the inclined hole 20; a drain pipe 21 provided at the bottom end of the water receiving tank 5;

[0038] Adopting the above technical solution can reduce the potential energy of the billet head falling, and at the same time automatically separate the billet head and cutting slag generated by the flame cutting machine when cutting the intermediate billet, reduce the damage of the billet head impact to the scrap steel bucket 6, and eliminate the subsequent manual separation work of cutting slag and scrap steel. During work, the billet head enters the vertical chute through the feed inlet. When the billet head falls on the inclined plane, it will bounce up and enter the inclined chute. The cutting slag and granulated water generated by the flame cutting machine to cut the steel reach the flap 4 before the billet head. Under the blocking action of the flap 4, the cutting slag and granulated water enter the water receiving tank 5 through the inclined hole 20 to complete collection. Subsequently, the billet head impacts the flap 4, reducing the potential energy of the billet head. The first buffer member, that is, the flap 4, will rotate to open the discharge outlet of the chute 1 after being impacted, thereby discharging the billet head. When it falls into the scrap steel bucket 6, the billet head will not cause a large impact on the scrap steel bucket 6, protecting the structure of the scrap steel bucket 6 and greatly extending the service life of the scrap steel bucket 6.

[0039] Furthermore, as Figure 4As shown in the figure, one end of the support plate 3 is hinged to a rotating plate 16. A rotating groove 17 is formed in the area where the rotating plate 16 abuts against the support plate 3. At the corresponding position of the other end of the support plate 3 and the rotating plate 16, a first mounting hole 22 is provided. A second bolt 18 and a second nut 19 are arranged in the first mounting hole 22.

[0040] Adopting the above technical solution can facilitate the disassembly of the flap 4. Since the flap 4 is often impacted during use, its surface is easily smashed and needs to be replaced regularly. When replacing, the second nut 19 fixed to one end of the second bolt 18 is untied, and the rotating plate 16 is rotated to open the rotating groove 17, so that the end shaft 15 of the flap 4 can be disassembled from the support plate 3.

[0041] Furthermore, as Figure 1 and Figure 3 shown in the figure, the buffer device further includes a second buffer member arranged in the vertical groove. The first buffer member is used to reduce the potential energy of the material head before it enters the inclined groove; in this embodiment, the second buffer member includes: a chain 2 with one end fixed to the steel support above the vertical groove. The other end of the chain 2 hangs down under the action of gravity to form a free end. A plurality of chains 2 are arranged and are flush with each other to form a blocking surface. The chain 2 is arranged 500 mm in front of the flap 4.

[0042] Adopting the above technical solution further improves the reduction of the potential energy of the material head. After the material head falls from the vertical groove of the chute 1, since it will bounce when it hits the inclined plane and hits the heavy chain 2, the potential energy is reduced when it rolls down overcoming the bearing capacity of the chain 2. Cooperating with the flap 4 can fully reduce the potential energy of the material head. At this time, the material head will not cause a large impact on the scrap steel bucket 6.

[0043] Furthermore, as Figure 3 and Figure 5 shown in the figure, in this embodiment, a buffer plate 13 is connected to the free end of the chain 2. A convex rib 14 is arranged at the buffer plate 13 facing the feed inlet of the chute 1. The convex rib 14 is used to increase the weight of the buffer plate 13. To ensure that the buffer plate 13 will not tilt, at least two chains 2 are arranged and are symmetrically arranged with respect to the buffer plate 13.

[0044] Adopting the above technical solution can further improve the reduction effect of the potential energy of the material head by the chain 2. Since the weight of the material head is relatively large, relying solely on the chain 2 itself to reduce its potential energy has very limited effect. By connecting a buffer plate 13 to the free end of the chain 2, the overall weight of the chain 2 can be increased. After the material head falls from the vertical groove of the chute 1, since it will bounce when it hits the inclined plane and hits the buffer plate 13 of the heavy chain 2, the weight of the buffer plate 13 is much greater than the weight of the chain 2 itself. Therefore, it can more effectively resist the impact of the material head. By adding the buffer plate 13, it is suitable for reducing the potential energy of the material head with a relatively large weight.

[0045] AsFigure 1 and Figure 5 As shown in Figure 5 , the buffer device further includes a mounting member for connecting one end of the chain 2 to the steel bracket and connecting the free end to the buffer plate 13. The mounting member includes: a positioning pin 7 having a second mounting hole 11 for fixing the groove of the chain 2; a positioning plate 8 having a pin hole 9 for pressing the chain 2; a first bolt 10 and a first nut 12 are disposed in the second mounting hole 11;

[0046] Adopting the above technical solution can facilitate the disassembly and replacement of the chain 2 or the buffer plate 13. Since the buffer plate 13 is often impacted during use, its surface is easily smashed, and it needs to be replaced regularly. When replacing, loosen the first nut 12 fixed at one end of the first bolt 10, and pull out the first bolt 10 from the second mounting hole 11 of the positioning pin 7, then the positioning plate 8 that limits the chain 2 can be removed from the positioning pin 7. The above operation can facilitate the disassembly of the chain 2 or the buffer plate 13.

[0047] Working principle: When in use, after the stock head falls from the vertical groove of the chute 1, since it will bounce up when it falls on the inclined plane and hits the heavy chain 2, when overcoming the bearing capacity of the chain 2 and rolling down, the falling potential energy is reduced once. The cutting slag and granulated water reach the flap 4 before the stock head. Under the blocking action of the flap 4, the cutting slag and granulated water enter the water collecting tank 5 through the inclined hole 20 to complete the collection. Subsequently, the stock head hits the flap 4, causing the potential energy of the stock head to be reduced twice. The first buffer member, i.e., the flap 4, will rotate to open the discharge port of the chute 1 after being impacted, thereby discharging the stock head. When it falls into the scrap steel hopper 6, the stock head will not cause a large impact on the scrap steel hopper 6, protecting the structure of the scrap steel hopper 6 and greatly extending the service life of the scrap steel hopper 6.

[0048] Thus, a series of operations are completed. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
