Technical Field

[0001] This utility model relates to the field of drainage pipe production technology, and more specifically, to a centrifugal casting device for the production of bridge drainage pipes. Background Technology

[0002] Bridge drainage pipes are the core components of bridge drainage systems, used to quickly remove water from bridge surfaces, prevent water accumulation from eroding the structure, increasing bridge load, or affecting traffic safety. Bridge drainage pipes have the function of efficient drainage, preventing water from seeping into the beams, protecting bridge durability, avoiding structural corrosion and increased load pressure, and providing safety assurance by reducing the risk of vehicles skidding in rainy weather. In the production process of bridge drainage pipes, centrifugal casting equipment is required to cast and shape the drainage pipes.

[0003] Although existing casting equipment can cast drainage pipes, traditional casting equipment can usually only produce a few dozen per day, which is not efficient and cannot meet the needs of mass production of drainage pipes. Therefore, it is necessary to design a centrifugal casting equipment for the production of bridge drainage pipes in order to avoid this phenomenon. Utility Model Content

[0008] Preferably, a tail end cap is embedded inside the second circular groove, a tail baffle is embedded inside the first circular groove, and the tail baffle is annular. Both the tail end cap and the tail baffle are located inside the annular portion, and a head retaining ring is embedded inside the straight cylindrical portion.

[0009] Preferably, a servo motor is installed on the top of the worktable and is fixed on one side of the bearing housing. The output end of the servo motor is fitted with a drive pulley through a shaft. A driven pulley is coaxially arranged on the surface of one of the rotating shafts and is connected to the drive pulley by a transmission belt.

[0010] Preferably, the outer surface of the straight section has two symmetrical first positioning holes, and the outer surface of the annular section has two symmetrical second positioning holes.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0018] like Figure 1 , Figure 2 , Figure 4 as well as Figure 6As shown, this is a schematic diagram of the centrifugal casting device used for the production of bridge drainage pipes in this embodiment. The centrifugal casting device in this embodiment includes a workbench 1. Two sets of bearing seats 2 are provided on the top of the workbench 1, and the two sets of bearing seats 2 are symmetrically distributed and fixed in the mounting frame 11. A rotating shaft 3 is provided between each set of bearing seats 2 through bearings. Two transmission rollers 4 are coaxially provided on the surface of the rotating shaft 3. A mold 5 is provided on the top of the transmission rollers 4. The mold 5 includes a straight cylindrical part 501, a frustum part 502, an annular part 503 and a guide ring 504. One end of the straight cylindrical part 501 is fixedly connected to the frustum part 502, and one end of the frustum part 502 is fixedly connected to the annular part 503. The inner wall of the annular part 503 is provided with a first... A first circular groove 6 and a second circular groove 7 are provided. A tail end cap 8 is embedded inside the second circular groove 7. A tail baffle 9 is embedded inside the first circular groove 6. The tail baffle 9 is annular. Both the tail end cap 8 and the tail baffle 9 are located inside the annular part 503. A head retaining ring 10 is embedded inside the straight cylindrical part 501. Before centrifugal casting, the tail end cap 8, the tail baffle 9 and the head retaining ring 10 need to be assembled into the mold 5. First, the tail end cap 8 is inserted into the second circular groove 7. Then, the tail baffle 9 is inserted into the first circular groove 6 and limited. Then, the head retaining ring 10 is inserted into the straight cylindrical part 501 and limited. This makes the tail end cap 8, the tail baffle 9 and the head retaining ring 10 form a centrifugal casting cavity in the mold 5. like Figure 2 As shown, in this embodiment, two guide rings 504 are coaxially arranged on the outer surface of the straight cylinder 501, and the two guide rings 504 are located above the corresponding two transmission rollers 4. During the centrifugal casting process, the mold 5 is placed on the two sets of transmission rollers 4, so that the two guide rings 504 of the mold 5 abut against the surfaces of the two sets of transmission rollers 4. Then, molten iron at 1200 degrees Celsius is injected into the mold 5 from one end of the straight cylinder 501, so that the molten iron is retained in the cavity. Then, the rotating shaft 3 drives one of the sets of transmission rollers 4 to perform centrifugal casting. The mold rotates, and another set of transmission rollers 4 assists in the rotation. In conjunction with two guide rings 504 set on the surface of the mold 5, the mold 5 rotates together with the guide rings 504 at a speed of 1200 rpm for three minutes. This centrifugal force is used to evenly distribute the molten iron on the inner wall of the mold 5, thereby forming a casting to produce a drain pipe. Through this centrifugal casting method, about 400 drain pipe products can usually be produced per day, which is several times higher than the daily production of traditional casting methods. This improves processing efficiency, better meets the needs of mass production of drain pipes, and is highly practical.

[0019] It is worth noting that in this embodiment, the diameter of the second circular groove 7 is slightly smaller than that of the first circular groove 6, and the top of the workbench 1 is provided with an installation frame 11. The installation frame 11 can be fitted with plates to protect the centrifugal casting device.

[0020] like Figure 2 as well as Figure 5 As shown, in this embodiment, the outer surface of the straight cylindrical portion 501 has two symmetrical first positioning holes 16, and the outer surface of the annular portion 503 has two symmetrical second positioning holes 17. Limiting pins 18 are inserted into the interior of both the first positioning holes 16 and the second positioning holes 17. The multiple limiting pins 18 can be divided into two groups. One group of limiting pins 18 abuts against the tail baffle 9, while the other group of limiting pins 18 abuts against the head retaining ring 10. After the tail baffle 9 and the head retaining ring 10 are respectively embedded in the mold 5, the two groups of limiting pins 18 are respectively inserted into the first positioning holes 16 and the second positioning holes 17. The tail baffle 9 is limited and blocked by one group of limiting pins 18, while the head retaining ring 10 is limited and blocked by the other group of limiting pins 18, so as to complete the assembly.

[0021] like Figure 1 as well as Figure 3 As shown, in order to provide power to the rotating shaft 3, a servo motor 12 is installed on the top of the workbench 1 in this embodiment, and the servo motor 12 is fixed on one side of the bearing seat 2. The output end of the servo motor 12 is fitted with a drive pulley 13 through a shaft. A driven pulley 14 is coaxially arranged on the surface of one of the rotating shafts 3, and the driven pulley 14 and the drive pulley 13 are connected by a transmission belt 15. By controlling the servo motor 12, the output end of the servo motor 12 drives the drive pulley 13 to rotate. Through the transmission belt 15, the driven pulley 14 is driven to rotate, and the driven pulley 14 can drive the fitted rotating shaft 3 to rotate together, so that the rotating shaft 3 drives the transmission roller 4.
