Description

Technical Field

[0001] This utility model belongs to the technical field of roll casting equipment, specifically relating to a multi-channel roll casting equipment. Background Technology

[0002] Rolls are the core components of rolling mills, consisting of three parts: the roll body, the roll neck, and the shaft end. They apply pressure to metal through rotation, causing plastic deformation to shape and size the desired product. Rolls require high strength, high wear resistance, and good thermal stability. Roll casting equipment is specifically designed for producing rolls. Through a casting process, molten metal is poured into roll molds, and after cooling, solidification, and finishing, rolls of the predetermined shape, size, and performance are obtained.

[0003] Existing Chinese patent CN 206811084 U discloses a large-scale multi-channel roll casting device, relating to the field of roll casting equipment. It comprises a housing, a first pouring pipe, a first pouring channel, a second pouring pipe, a second pouring channel, a third pouring channel, a drain pipe, a direct pouring pipe, a direct pouring channel, a plug, electroslag, and graphite rods. The housing consists of a base plate, a second roll head box, a roll neck box, a roll body box, a first riser, a second riser, and a first roll head box. The housing is equipped with the first, second, and third pouring channels, which are connected to the direct pouring channel. A plug is provided on the direct pouring channel, and the plug is located inside the intermediate box. This invention has a simple structure and convenient operation, effectively improving the roll casting progress and enabling one-time forming of roll castings during the casting process, greatly improving the production quality and efficiency of roll manufacturing.

[0004] The existing technical solutions mentioned above have the following drawbacks: Although the casting progress of the rolls can be improved by setting multiple pouring channels, the method of heating the rolls for secondary melting is time-consuming and labor-intensive in order to solve quality problems such as mold cracks, shrinkage cavities, and porosity. Moreover, there is still a certain probability of cracks being generated during the secondary melting and solidification process, resulting in low production quality. Furthermore, the solidification speed of the pouring liquid is relatively slow, leading to low production efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a multi-channel roll casting equipment to solve the technical problem of easy cracking in casting, thereby improving production efficiency and accelerating the solidification of the casting liquid.

[0006] To solve the above-mentioned technical problems, this utility model provides a multi-channel roll casting equipment, including three casting equipment bodies. The bottom of each casting equipment body is provided with a base, and the top of each base is uniformly connected with three auxiliary plates. The top of each auxiliary plate is provided with an annular groove. The top of both the base and the auxiliary plates is provided with through holes. A vibration device is provided between the casting equipment body and the base, and a moving component is provided on one side of each casting equipment body.

[0007] Furthermore, the vibration device includes a connecting plate, a vibrating element is provided at the bottom of the connecting plate, and three vibrating rods are evenly connected to the top of the connecting plate.

[0008] Furthermore, a kit is connected to the top of the vibration rod, and three support rods are evenly connected to the top of the kit.

[0009] Furthermore, the top of the kit is provided with a connecting sleeve, the bottom end of which is connected to the top end of the support rod. The vibration device is sleeved on the outside of the casting equipment body, and the vibration rod passes through the corresponding through hole.

[0010] Furthermore, the vibrating element is specifically a high-frequency vibrator, and the output end of the vibrating element is connected to the bottom end of the connecting plate via a transmission connection.

[0011] Furthermore, the movable component includes a bracket, a sliding groove is provided on one side of the bracket, a circular groove is provided at the top of the bracket, and a threaded rod is rotatably connected inside the sliding groove.

[0012] Furthermore, a driver is provided on the top of the bracket, specifically a motor. The output end of the driver is connected to the top end of the threaded rod. A slide plate is provided on one side of the bracket. A threaded hole is opened at the top end of the slide plate. The outer wall of the threaded rod is threadedly connected to the inner wall of the threaded hole. One end of the slide plate is slidably connected to the inner wall of the groove.

[0013] Furthermore, both sides of the slide plate are connected to connectors, and the bottom ends of the slide plate and the connectors are connected to a central rod. The bottom ends of the connectors and the slide plate are respectively engaged with the top end of the casting equipment body.

[0014] The beneficial effects of this utility model are:

[0015] 1. Through a series of vibrations driven by a vibrating component, the molten metal poured inside the casting equipment is subjected to uniform and sufficient vibration. This vibration effectively promotes the rise and collapse of air bubbles in the molten metal to the surface, thereby significantly reducing defects such as air bubbles, gaps, and porosity inside the casting after solidification. This improves the density and overall quality of the casting. Vibration also helps the molten metal to solidify more evenly, avoiding stress concentration and uneven solidification caused by premature solidification in certain areas. This not only improves the mechanical properties of the casting but also enhances its surface quality and dimensional accuracy.

[0016] 2. By making the center of the casting liquid hollow, both the outer and inner walls of the casting are simultaneously cooled by the cooling medium during solidification. This uniform cooling method significantly shortens the solidification time of the casting liquid, improving production efficiency. The hollow design at the center of the casting liquid avoids stress concentration and excessive temperature gradients caused by uneven cooling in the central area, thus effectively reducing the generation of bubbles and gaps during solidification. Simultaneously, because the casting liquid solidifies more uniformly, the internal structure of the casting is denser, improving the overall quality of the casting.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Example:

[0027] like Figures 1 to 4 As shown, a multi-channel roll casting equipment includes three casting equipment bodies 1. A base 2 is provided at the bottom of each casting equipment body 1. Three auxiliary plates 3 are evenly connected to the top of each base 2. Annular grooves 4 are formed at the top of each auxiliary plate 3. Through holes 5 are formed at the top of both the base 2 and the auxiliary plates 3. A vibration device 6 is provided between the casting equipment body 1 and the base 2. A moving component 7 is provided on one side of each casting equipment body 1. The vibration device 6 includes a connecting plate 61. A vibrating element 62 is provided at the bottom of the connecting plate 61. Three vibrating rods 63 are evenly connected to the top of the connecting plate 61. A kit 64 is connected to the top of each vibrating rod 63. Three support rods 65 are evenly connected to the top of the kit 64.

[0028] The top of the kit 64 is provided with a connecting sleeve 66, the bottom end of which is connected to the top end of the support rod 65. The vibration device 6 is sleeved on the outside of the casting equipment body 1, and the vibration rod 63 passes through the corresponding through hole 5. The vibration element 62 is specifically a high-frequency vibrator, and the output end of the vibration element 62 is connected to the bottom end of the connecting plate 61 for transmission.

[0029] The inner wall of the connecting sleeve 66 is connected to the outer wall of the casting equipment body 1. Three support rods 65 are supported at the bottom of the connecting sleeve 66 to assist the casting equipment body 1 in vibration. The vibration element 62 is activated, causing the connecting plate 61 to vibrate. The connecting plate 61 then drives the vibration rod 63 to vibrate, which in turn drives the support rods 65 and the connecting sleeve 66 to vibrate. This vibrates the molten metal poured into the casting equipment body 1, eliminating air bubbles and reducing gaps and pores generated during the solidification process. This improves the solidification effect of the molten metal. The vibration rod 63 passes through the interior of the through hole 5, and the outer wall of the vibration rod 63 does not adhere to the inner wall of the support rod 65, avoiding obstruction of the output end of the vibration element 62 from performing high-frequency vibration.

[0030] like Figure 4 As shown, the moving component 7 includes a bracket 71. A groove 72 is formed on one side of the bracket 71, and a circular groove 73 is formed at the top of the bracket 71. A threaded rod 74 is rotatably connected inside the groove 72. A driver 75, specifically a motor, is mounted on the top of the bracket 71. The output end of the driver 75 is connected to the top of the threaded rod 74. A sliding plate 76 is mounted on one side of the bracket 71. A threaded hole 77 is formed at the top of the sliding plate 76. The outer wall of the threaded rod 74 is threadedly connected to the inner wall of the threaded hole 77. One end of the sliding plate 76 is slidably connected to the inner wall of the groove 72. Connectors 78 are connected to both sides of the sliding plate 76. A center rod 79 is connected to the bottom of both the sliding plate 76 and the connectors 78. The bottom ends of the connectors 78 and the sliding plate 76 are respectively engaged with the top of the casting equipment body 1.

[0031] The center rod 79 is inserted into the center of the casting equipment body 1. While the casting equipment body 1 is filled with casting liquid, the center of the casting liquid is hollow. This design allows the outer and inner walls of the casting liquid to cool simultaneously during solidification, accelerating the solidification process and reducing the formation of air bubbles and gaps. Once the hollow casting liquid has solidified, the process is activated. The output end of the driver 75 rotates, driving the threaded rod 74 to rotate. The rotation of the threaded rod 74 causes relative movement between its outer wall and the inner wall of the threaded hole 77. The sliding plate 76 slides upwards towards the slide groove 72, removing the center rod 79 from the casting equipment body 1. Then, the casting liquid is poured again into the solidified center for a secondary pouring.

[0032] In summary, rolls cast in this manner have fewer internal air bubbles and cracks, resulting in better cemented casting.
