DETAILED DESCRIPTION
[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] See also Figure 1 , Figure 2 and Figure 3 The utility model provides an alloy adding device for ductile iron casting, including a column 1, a flange hole is opened at the lower end of the column 1, the column 1 can be fixedly installed at a work station by screws, the column 1 is rotatably installed with a sleeve 2 through a bearing, an electric rotating platform 3 is fixedly installed on the upper end of the column 1, the electric rotating platform 3 is a hollow existing device, and has structures such as a servo motor, a worm gear, a worm and an annular table, the annular table of the electric rotating platform 3 is fixedly assembled with the sleeve 2, and the sleeve 2 can be rotated circumferentially by the electric rotating platform 3.
[0024] A first support arm 4 and a second support arm 18 are fixedly installed on the same side of the sleeve 2. The first support arm 4 is located above the second support arm 18. A rotating shaft 10 is rotatably installed between the first support arm 4 and the second support arm 18 through a bearing. The rotating shaft 10 is vertically arranged. A reduction motor 5 is fixedly installed on the upper side of the first support arm 4. The output end of the reduction motor 5 is connected and assembled with the upper end of the rotating shaft 10. The rotating shaft 10 can be rotated by the reduction motor 5.
[0025] A disc 6 is fixedly installed in the middle of the rotating shaft 10, and a storage tank 7 is evenly fixedly installed on the circumferential side of the disc 6. The storage tank 7 is an existing component composed of a tank body, a filling cover and other structures, which is used to store various alloy powders respectively. A square tube 15 is installed at the lower end of the storage tank 7. The square tube 15 has a through groove along the radial direction of the disc 6. A baffle 13 is inserted in the through groove. The baffle 13 has a material trough 16. The baffle 13 can translate in the through groove. When the material trough 16 is located inside the square tube 15, the alloy powder inside the storage tank 7 can be discharged downward. When the material trough 16 is located outside the square tube 15, the baffle 13 blocks the square tube 15. In this state, the alloy powder in the storage tank 7 will not be discharged.
[0026] To facilitate the control of the baffle 13, the material storage tank 7 is installed with an elastic structure 8 for resetting the baffle 13. The elastic structure 8 can enable the baffle 13 to have a force to reset close to the rotating shaft 10. After resetting, the material trough 16 is located outside the square tube 15; the second support arm 18 is installed with a pushing structure 9 for pressing against the baffle 13. The pushing structure 9 is used to push the aligned baffle 13 to the side away from the rotating shaft 10. After pushing, the material trough 16 is located inside the square tube 15.
[0027] The number of the storage tanks 7 is 2 to 6 distributed in a circle to meet the needs of the types of alloy powders. Different types of alloy powders are stored independently in the storage tanks 7 .
[0028] Specifically, the elastic structure 8 includes a guide rod 84 and a spring 81. A linear bearing 82 is fixedly installed on the lower side of the storage tank 7 through a support rod. The linear bearing 82 is horizontally arranged. A guide rod 84 is slidably installed in the linear bearing 82. One end of the guide rod 84 is fixedly assembled with the baffle 13. The guide rod 84 is sleeved with a spring 81, and the spring 81 is against the baffle 13 and the linear bearing 82; the guide rod 84 can slide horizontally in the linear bearing 82, and the spring 81 enables the baffle 13 to have a force to translate toward the rotating shaft 10.
[0029] A limit ring 83 is fixedly mounted on one end of the guide rod 84 away from the baffle 13. The limit ring 83 is used to limit the limit position of the guide rod 84 to return to the rotation shaft 10 to prevent the baffle 13 from detaching from the square tube 15 and causing leakage of alloy powder.
[0030] Specifically, the pushing structure 9 includes a pushing block 91 and a first guide wheel 93. The pushing block 91 is fixedly installed on the upper side of the second support arm 18 through a support seat. A first slope 92 is provided on the front side of the pushing block 91. The end surface of the pushing block 91 away from the rotating shaft 10 and the first slope 92 are evenly rotated and installed with the first guide wheel 93; the first slope 92 has the function of guiding the baffle 13 to move to the side away from the rotating shaft 10, and the setting of the first guide wheel 93 can reduce the friction when it abuts against the baffle 13, thereby improving the smoothness of the abutment process.
[0031] A second slope 17 matching the first slope 92 is provided at the end of the baffle 13 close to the rotating shaft 10; "matching" here means that when the baffle 13 rotates to be located at the pushing block 91, the second slope 17 is located on the rear side of the baffle 13, and the first slope 92 and the second slope 17 have the same inclination direction, so that they can interact with each other to complete the action of pushing the baffle 13.
[0032] Second guide wheels 14 for contacting the side wall of the baffle 13 are rotatably mounted at the four corners of the square tube 15 ; the second guide wheels 14 can improve the accuracy and smoothness of the translation of the baffle 13 and avoid excessive contact between the baffle 13 and the inner surface of the square tube 15 to increase friction.
[0033] A collecting hopper 12 is fixedly installed at the end of the second support arm 18 away from the sleeve 2, and a guide pipe 11 is installed on the lower side of the collecting hopper 12; the collecting hopper 12 is used to collect the alloy powder falling from the upper square tube 15 and guide it to the smelting furnace through the guide pipe 11, which can compensate for the conveying distance of the alloy powder and improve the conveying accuracy of the alloy powder.
[0034] The working principle of this embodiment:
[0035] During installation, the column 1 is set at a position close to the smelting furnace, and the electric rotating platform 3 and the reduction motor 5 are electrically connected to the control cabinet of the external smelting furnace through wires, and are uniformly controlled by the controller on the control cabinet.
[0036] The storage tank 7 close to the front side of the pushing structure 9 is the first one, and the others are arranged clockwise as the second, third, fourth, and so on from a top view. The alloy powders are pre-stored in the storage tanks 7 in a predetermined order of placement.
[0037] In the initial state, the electric rotating platform 3 drives all components to turn at least 90° through the sleeve 2, the first support arm 4 and the second support arm 18, avoiding the smelting furnace to facilitate the input of raw materials; during smelting, the electric rotating platform 3 drives all components to rotate back through the sleeve 2, the first support arm 4 and the second support arm 18 until the guide tube 11 is located above the smelting furnace.
[0038] When alloy powder is added as required, the reduction motor 5 drives all storage tanks 7 to rotate counterclockwise at a top-down angle via the rotating shaft 10 and the disc 6. The first storage tank 7 close to the pushing structure 9 first reaches the top of the collecting hopper 12. At this time, the second slope 17 gradually abuts against the first guide wheel 93 arranged on the pushing block 91, so that the baffle 13 moves away from the rotating shaft 10 until the square tube 15 is directly above the collecting hopper 12. The reduction motor 5 stops rotating. At this time, the material chute 16 is located inside the square tube 15, and the alloy powder in the corresponding storage tank 7 enters the smelting furnace through the collecting hopper 12 and the guide tube 11.
[0039] When the next alloy powder needs to be added, the disc 6 is rotated counterclockwise again, and the baffle 13 located above the collecting hopper 12 is gradually separated from the pushing structure 9 and reset through the elastic structure 8, while the baffle 13 on the lower side of the next storage tank 7 is against the pushing structure 9. This can be repeated to add the alloy powder according to the amount, sequence and timing, and reset after completion.
