Description

Technical Field

[0001] This utility model belongs to the field of rolling mill manufacturing technology, specifically relating to an easily identifiable centrifugal rolling mill bottom riser. Background Technology

[0002] The molding of centrifugal roll necks requires the use of base samples and risers. Base samples are used to make the base box, and risers are used to make the risers. The number of moldings per day is large, and the number and specifications of base and riser samples selected for each batch are also large. The selection of base and riser samples relies entirely on manual measurement and selection. Whether it is possible to make them easy for people to identify, prevent confusion in personnel memory, and ensure that the required base and riser samples are selected and used on the corresponding boxes has a significant impact on sand box molding and product production.

[0003] When molding the bottom box and riser of the centrifugal roll neck, the required bottom and riser patterns must be manually selected from the pattern stack in the pattern storage area and hoisted one by one onto the corresponding pattern in the pounding area. Then, the necessary box rings are selected for pounding and securing. Patterns only have specification markings welded to the top. Some patterns are quite tall, making it difficult for personnel to climb onto them to check the markings. When using patterns, a release agent is applied to the pattern body, making it difficult to mark. If the pattern selection personnel make a mistake, the wrong pattern can easily lead to incorrect bottom box or riser sand mold making. Furthermore, the pounding area has a large number and specifications of patterns, many of which are similar in shape and have indistinct appearances. If the pattern is not properly secured on the pattern, resulting in an upside-down shape, it can also lead to incorrect sand mold making. Figure 4 As shown, because the bottom box and riser are demolded with the larger end facing up and the smaller end facing down, personnel can only measure the size of the larger end. Since the bottom box has a bottom, the size of the smaller end is difficult to measure. The size of the smaller end of the riser needs to be measured when the riser is flipped over. Errors are often not detected in time during demolding, which can significantly impact subsequent processes. Firstly, the sand mold flows into the sand box for the spraying process after demolding. If the bottom sample or riser is incorrect, it will require re-spraying after the spraying process is completed, increasing the workload. Secondly, after spraying, it flows into the casting process, which can cause minor issues like process defects or, in severe cases, insufficient product output, leading to rework and significant quality losses. Utility Model Content

[0004] To address the problem of difficulty in observing the top markings when manually selecting bottom risers in existing technologies, and to solve the problem of difficulty in checking during demolding if the wrong pattern is used, this utility model provides an easily identifiable centrifugal roll bottom riser that allows for convenient observation of the markings on the marking plate.

[0005] The technical solution adopted by this utility model for an easily identifiable centrifugal roll bottom riser is as follows:

[0006] A centrifugal roll bottom sample that is easy to identify includes a sample body with a mark on the top and a base plate at the bottom of the sample body. A lifting hole is opened at the center of the sample body and the base plate. The sample body is characterized in that: the base plate is provided with multiple marking plates that can be flipped up and down and respectively attached to the upper surface and the lower surface of the base plate. Each marking plate is marked on both the upper and lower sides.

[0007] The signboard is fixedly connected to the base plate via a fixed structure.

[0008] A further improvement of this utility model is that each signboard is arranged in an arc shape, and the number of signboards is even, and they are arranged symmetrically on both sides of the sample.

[0009] A further improvement of this utility model is that: the side wall of the base plate is provided with a bottom pivot with the same curvature as the base plate for each signboard, and the outer arc side of each signboard is provided with a top pivot with the same curvature as the corresponding signboard for the position of the bottom pivot.

[0010] A further improvement of the above-mentioned technical solution of this utility model is that each bottom rotating shaft is connected to the corresponding top rotating shaft through a connecting rod, and the two ends of the connecting rod are respectively hinged to the corresponding bottom rotating shaft and the top rotating shaft.

[0011] A further improvement of the present invention is that each of the signboards is fixedly connected to the base plate by multiple sets of fixing structures, and the multiple sets of fixing structures are evenly arranged along the outer arc side of the corresponding signboard.

[0012] A further improvement of the above-mentioned technical solution of this utility model is that: each set of fixing structures includes a connecting block for connecting the sign plate and the base plate, and each sign plate has a top slot that cooperates with the connecting block at the position corresponding to the position of the connecting block. The side wall of the base plate has a bottom slot that cooperates with the connecting block at the position corresponding to each top slot. The two ends of the connecting block are respectively inserted into the corresponding top slot and bottom slot.

[0013] Due to the adoption of the above technical solution, the technical progress achieved by this utility model includes:

[0014] When not in use, this utility model is placed with the base plate facing down and the label on the sample facing up. The label plate is located above the base plate and is attached to the upper surface of the base plate. Thus, when workers select a bottom sample, they do not need to observe the label on the top of the sample, but only need to observe the label on the label plate to know the model of the current bottom sample, reducing sample selection errors.

[0015] When using this invention, the marking plate is rotated so that it is located below the base plate and in contact with the lower surface of the base plate. When demolding, the bottom plate of the bottom mold is demolded with the bottom mold facing upwards. At this time, the model of the bottom mold being demolded can be known by observing the marking on the marking plate. This ensures that if the wrong bottom mold is used, it is easy to check and can be detected in time during demolding, thus avoiding the flow of unqualified sand molds into subsequent processes and causing production impact.

[0016] When the signboard is attached to the upper or lower surface of the base plate, the present invention can fix the signboard to the base plate through the fixed structure, thereby preventing the signboard from swaying back and forth during hoisting.

[0017] In this invention, since the number of marking plates is even and they are arranged symmetrically on both sides of the sample, when the marking plates are in contact with the lower surface of the base plate, the bottom riser sample can be placed stably, preventing it from tipping over.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. In the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessarily obscuring the concept of this utility model.

[0028] First refer to Figure 1 and Figure 3 As can be seen, this utility model includes a sample 1, to which a base plate 2 is fixedly connected. A label indicating the current sample 1 model is welded to the top of the sample 1. A connecting lifting hole 3 is formed at the center of the sample 1 and the base plate 2. Multiple up-and-down rotating label plates 4 are mounted on the base plate 2. The number of label plates 4 is even, and the multiple label plates 4 are arranged symmetrically in a mirror image with the sample 1 as the center. Each label plate 4 has a label indicating the current sample 1 model welded to both its upper and lower surfaces. When a label plate 4 is rotated upwards, it fits against the upper surface of the base plate 2. When a label plate 4 is rotated downwards by 180°, it fits against the lower surface of the base plate 2. In this embodiment, each label plate 4 is an arc-shaped plate with the same curvature as the base plate 2. The diameter of the outer arc side of the arc-shaped plate is the same as the diameter of the base plate 2, and the diameter of the inner arc side of the arc-shaped plate is the same as the diameter of the sample 1.

[0029] In this invention, the signboard 4 can be hinged to the base plate 2 through various hinge methods, thereby achieving a 180° vertical rotation. In this embodiment, a bottom pivot 21 is provided on the side wall of the base plate 2 corresponding to the position of each signboard 4. The curvature of the bottom pivot 21 is the same as that of the base plate 2. A top pivot 41 is provided on the outer arc side of each signboard 4 corresponding to the position of the bottom pivot 21. The curvature of the top pivot 41 is the same as that of the outer arc side of the signboard 4. At the same time, the top pivot 41 is connected to the corresponding bottom pivot 21 through a connecting rod 6. The two ends of the connecting rod 6 are respectively hinged to the corresponding top pivot 41 and bottom pivot 21.

[0030] When the signboard 4 is attached to the upper or lower surface of the base plate 2, the signboard 4 is fixed to the base plate 2 by the fixing structure 5 to prevent the signboard 4 from shaking and being damaged during hoisting of this utility model; in this utility model, each signboard 4 should be connected to the base plate 2 by at least two sets of fixing structures 5, and multiple sets of fixing structures 5 are evenly distributed on the outer arc side of the same signboard 4. In this embodiment, as shown... Figure 2 As shown, each set of fixing structures 5 includes a top slot 52 opened on the outer arc side of the sign plate 4, and a bottom slot 53 opened on the side wall of the base plate 2 corresponding to the position of the top slot 52. A U-shaped connecting block 51 is inserted into the top slot 52 and the bottom slot 53. The connecting block 51 can be made of elastic material such as rubber. The two ends of the connecting block 51 are respectively inserted into the bottom slot 53 and the top slot 52, thereby fixing the sign plate 4 and the base plate 2 together.

[0031] The working principle of the easily identifiable centrifugal roll bottom sample in this embodiment is as follows: When not in use, the base plate 2 of this invention is placed downwards and the marking on the sample 1 is upwards. The marking plate 4 is located above the base plate 2 and is attached to the upper surface of the base plate 2, and is fixed together by the fixing structure 5. Therefore, when workers select a bottom sample, they do not need to observe the marking on the top of the sample 1, but only need to observe the marking on the marking plate 4 to know the model of the current bottom sample, reducing selection errors.

[0032] In this embodiment, the present invention is lifted, and then the connecting block 51 is pulled out from the bottom slot 53 and the top slot 52. The marking plate 4 is rotated 180° to be below the base plate 2 and in contact with the lower surface of the base plate 2. Then, the connecting block 51 is reinserted into the bottom slot 53 and the top slot 52, thereby fixing the marking plate 4 and the lower surface of the base plate 2 together. When demolding, the base plate 2 of the bottom mold is demolded with the bottom mold facing upwards. At this time, the model of the bottom mold being demolded can be identified by observing the marking on the marking plate 4. This ensures that if the wrong bottom mold is used, it is easy to check and can be detected in time during demolding, avoiding the flow of unqualified sand molds into subsequent processes and causing production impact.

[0033] In the above embodiments, this utility model provides an easily identifiable centrifugal roll bottom liner. When workers select a bottom liner, they do not need to observe the markings on the top of the sample; they only need to observe the markings on the marking plate to know the model of the current bottom liner, reducing selection errors. At the same time, when demolding, the bottom plate of the bottom liner is demolded with the bottom plate facing upwards. At this time, by observing the markings on the marking plate, the model of the bottom liner being demolded can be known, ensuring that if the wrong bottom liner is used, it is easy to check and can be detected in time during demolding, avoiding the flow of unqualified sand molds into subsequent processes and causing production impact.

[0034] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Various modifications and improvements made to the technical solutions of the present invention by those skilled in the art without departing from the design concept of the present invention should fall within the protection scope of the present invention. The technical content for which protection is sought in the present invention has been fully described in the claims.
