Description

Technical Field

[0001] The utility model relates to the technical field of rolling rollers, in particular to a casting device for rolling roller castings. Background Art

[0002] Rollers are crucial components in roll forming. Rollers must withstand significant rolling forces during the rolling process, so they are typically produced through a single-stage casting process. Rollers are cast in roll casting molds. Roller casting molds consist of a runner and a roll cavity. Currently known roll casting molds feature a gate at the top, directly connected to the top of the roll cavity. Molten steel enters the mold through the gate, gradually filling it. To prevent the molten steel from shrinking after casting, potentially causing the casting to fail to meet requirements, a certain amount of molten steel is injected into the gate to fill the gap.

[0003] Upon investigation, a Chinese utility model patent disclosed a roller casting mold (publication number: CN202291293U), which includes several layers of sand boxes stacked in sequence, with a roller cavity for casting inside the sand box, and a runner is provided on one side of the sand box and the roller cavity, and the lower end of the runner is tangentially connected to the bottom of the roller cavity.

[0004] In the above patent, during casting, the molten steel enters the end of the runner from the runner. Due to the bull-horn-shaped runner, the flow rate of the molten steel is reduced, the molten steel is buffered, and then enters the roller cavity tangentially, which greatly reduces the impact of the molten steel on the bottom of the roller cavity; at the same time, the molten steel enters tangentially from the bottom of the roller cavity, generating rotation, so that the waste slag or gas in the molten steel is easier to be discharged directly from the top. However, after casting, the roller body is tightly combined with the mold, demolding is inconvenient, and the casting efficiency is low.

[0005] Therefore, the utility model provides a casting device for roll castings to solve the above problems. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] The utility model provides a casting device for roller castings, such as Figure 1 、 Figure 2 and Figure 4 As shown, the casting device of the roll casting includes a base plate 1, a pouring pipe 2 arranged on the base plate 1, a first clamping block 3 fixedly installed on the base plate 1, a second clamping block 4 movably installed on the base plate 1, and a fixing mechanism arranged on one side of the first clamping block 3 for convenient demoulding.

[0027] The fixing mechanism includes a first mold 5 movably mounted on one side of the first clamping block 3, a second mold 6 movably mounted on one side of the first mold 5, a clamping block 7 fixedly mounted on the first mold 5 and the second mold 6, and a hoop 8 arranged on the first mold 5 and the second mold 6. The clamping blocks 7 are distributed in a circular array on the first mold 5 and the second mold 6.

[0028] When the casting device of the roll casting is in use, the base plate 1 is placed in a suitable position, and the second mold 6 is manually aligned with the first mold 5. After alignment, the hoop 8 is manually clamped to the second mold 6 and the first mold 5. First, the clamping block on the hoop 8 is aligned with the gap between the two clamping blocks 7, and then the hoop 8 is pushed down until the clamping block on the hoop 8 is pushed to the bottom, and then the hoop 8 is rotated thirty degrees until the clamping block on the hoop 8 overlaps with the clamping block 7. According to this operation, the second mold 6 and the bottom of the first mold 5 are fixed through another hoop 8, and then the second mold 6 and the first mold 5 are placed inside the first clamping block 3, and then the second clamping block 4 is aligned and fitted with the first clamping block 3. The molten steel is injected into the interior of the pouring pipe 2, and flows into the interior of the first mold 5 and the second mold 6 through the pouring pipe 2, gradually filling the first mold 5 and the second mold 6. In order to prevent the volume of the molten steel from shrinking after casting, so that the casting cannot meet the requirements, a certain amount of molten steel is injected into the pouring pipe 2 for filling, and finally the casting is completed. When demolding is required, it is only necessary to separate the second clamping block 4 from the first clamping block 3, and take out the first mold 5 and the second mold 6. Then, the two hoop rings 8 are manually rotated in reverse so that the block on the hoop ring 8 is between the two clamping blocks 7, and then the hoop ring 8 is pulled outward to separate the hoop ring 8 from the first mold 5 and the second mold 6. Then, the first mold 5 and the second mold 6 are separated to take out the casting.

[0029] Furthermore, in order to fix the first clamping block 3 and the second clamping block 4, as shown in FIG. Figure 1 、 Figure 2 and Figure 5 As shown, the first clamping block 3 is fixedly connected to the two sides with fixed blocks 9, the second clamping block 4 is fixedly connected to the two sides with fixed plates 10, the interior of the fixed plate 10 is screwed with a threaded rod 11, and the interior of the fixed plate 10 and the fixed block 9 are provided with threaded holes that are compatible with the threaded rod 11.

[0030] When the casting device of the rolling mill casting is in use, after the second clamping block 4 is aligned and fitted with the first clamping block 3, the threaded rod 11 is manually rotated so that the threaded rod 11 connects and fixes the fixing block 9 and the fixing plate 10, thereby fixing the first clamping block 3 and the second clamping block 4. When demolding, the threaded rod 11 is manually rotated in the opposite direction to remove the threaded rod 11 from the fixing block 9 and the fixing plate 10, and then the first clamping block 3 and the second clamping block 4 are separated.

[0031] Furthermore, in order to fix the pouring pipe 2, as shown in FIG. Figure 1 、 Figure 2 and Figure 3 As shown, a plurality of support frames 12 are fixedly connected to the top of the bottom plate 1 , a limiting block 13 is fixedly connected to the top of the supporting frame 12 , and an inserting block 14 is slidably connected inside the limiting block 13 .

[0032] The top of the insert block 14 is fixedly connected to a limit plate 15 , the interior of the limit block 13 is slidably connected to a movable plate 16 , and the bottom of the limit plate 15 is fixedly connected to a plurality of telescopic rods 17 .

[0033] A first spring 18 is sleeved on the side surface of the telescopic rod 17 . One end of the first spring 18 is fixedly connected to the bottom of the limiting plate 15 , and the other end of the first spring 18 is fixedly connected to the top of the limiting block 13 .

[0034] When the casting device of the rolling mill casting is in use, when it is necessary to inject molten steel into the pouring pipe 2, first manually push the handle on the movable plate 16 to push the movable plate 16 into the inside of the limit block 13. When the inclined surface of the movable plate 16 contacts the inclined surface of the insert block 14, continue to push the movable plate 16 forward to push the insert block 14 upward. The upward movement of the insert block 14 drives the limit plate 15 to move upward. The upward movement of the limit plate 15 drives the telescopic rod 17 to extend and pulls the first spring 18 until the groove on the movable plate 16 moves to the position of the insert block 14. The insert block 14 will be quickly inserted into the inside of the groove on the movable plate 16 due to its own weight and the elastic potential energy of the first spring 18. The movable plate 16 limits the insert block 14, and the insert block 14 fixes the limit plate 15 and the pouring pipe 2.

[0035] Furthermore, in order to facilitate the removal of the movable plate 16, as shown in FIG. Figure 1 、 Figure 2 and Figure 5 As shown, a second spring 19 is provided inside the limit block 13, and a baffle 20 is slidably connected inside the limit block 13. One end of the second spring 19 is fixedly connected to one side of the limit block 13, and the other end of the second spring 19 is fixedly connected to one side of the baffle 20.

[0036] When the casting device of the rolling mill casting is in use, the movable plate 16 moves inside the limit block 13, and the movable plate 16 drives the baffle 20 to move synchronously. The second spring 19 is squeezed by the movement of the baffle 20 until the insert block 14 enters the inside of the groove on the movable plate 16. After the casting is completed, the limit plate 15 is manually pushed upward, and the movement of the limit plate 15 drives the insert block 14 to move synchronously. The insert block 14 is taken out from the inside of the groove of the movable plate 16, and the baffle 20 is pushed in the opposite direction by the elastic potential energy of the second spring 19. The reverse movement of the baffle 20 drives the movable plate 16 to move synchronously. Then, the movable plate 16 is taken out by manually pulling the handle on the movable plate 16.

[0037] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
