Description

Technical Field

[0001] The present invention relates to the technical field of alloy casting, and particularly relates to a cooling rotary casting machine and a casting method thereof. Background Art

[0002] Ferroalloy casting refers to the process of injecting liquid ferroalloy (commonly known as molten iron) into a mold to solidify it into an ingot. Except for aluminothermic method, ferrotungsten and vacuum solid decarburization reduction products, the pyrometallurgical process of ferroalloys ultimately obtains liquid ferroalloys. According to the different equipment used, there are three methods for ferroalloy casting: pit (site) casting, ingot mold casting, and casting machine casting.

[0003] The pit (site) casting method completes the ferroalloy casting in a specially constructed pit. The bottom and side walls of the pit are pre-laid with solid alloys having a similar composition to the alloy to be cast, and then the liquid alloy is injected and made to cover the entire pit as much as possible to form a thin layer, and the molten iron quickly solidifies. The ingot mold casting method is to carry out ferroalloy casting in a group or individual ingot molds. The casting machine casting method is to complete all processes of the entire casting process such as mold preparation, alloy injection, and demolding in the casting machine.

[0004] In the process of ferroalloy casting, in order to improve the alloy casting efficiency, a rotating mold is provided. A plurality of mold cavities are provided on the rotating mold, and ferroalloys are cast by pouring into the mold cavities, thereby improving the casting speed of ferroalloys.

[0025] Embodiment As Figure 1 、 Figure 2 shown, a cooling rotary casting machine according to the present invention includes a circular housing 1. On both sides of the circular housing 1, a first fixed platform 2 and a second fixed platform 3 are respectively provided, and both the first fixed platform 2 and the second fixed platform 3 are arranged on the ground. A rotary mechanism with a rotating function is provided inside the circular housing 1. As Figure 3 、 Figure 4As shown, the rotating mechanism includes a rotating center block 7 and rotating bodies 8 evenly arranged on the rotating center block 7. The cross-section of the rotating bodies 8 is fan-shaped, with a fan-shaped cross-section of 30 degrees. The rotating center block 7 is cylindrical, and the rotating bodies 8 are evenly spaced on the cylindrical surface of the rotating center block and circumscribe the cylindrical surface. In this embodiment, there are a total of six rotating bodies 8, with spaces for placing alloy molds 9 provided between adjacent rotating bodies 8. The angle between each rotating body 8 is 30 degrees. The rotating bodies 8 and the rotating center block 7 are welded to form an integral structure. One side of the rotating center block 7 is transmission-connected to the power element on the fixed platform 2 via a connecting rod 1 5, and the other side of the rotating center block 7 is rotationally connected to the fixed platform 2 3 via a connecting rod 2 6. The power element is a servo motor 4, and the mounting plate of the servo motor 4 is bolted to the top of the fixed platform 2. The output shaft of the servo motor 4 is connected to one end of the connecting rod 1 5, and the other end of the connecting rod 1 5 is fixedly connected to one side of the rotating center block 7. The connecting rod 1 5 is connected to the circular housing 1 via a bearing. One end of the connecting rod 2 6 is rotatably connected to the fixed platform 2 3, and the other end of the connecting rod 2 6 is fixedly connected to the other side of the rotating center block 7. The connecting rod 2 6 is connected to the circular shell 1 through a bearing. The output shaft of the servo motor 4 drives the connecting rod 1 5 to rotate, thereby driving the rotating center block 7 to rotate. When the rotating center block 7 rotates, the connecting rod 2 6 rotates on the fixed platform 2 3. The rotation of the rotating center block 7 drives the rotating body 8 to rotate. The servo motor 4 can drive the rotating body 8 to rotate at a uniform and slow speed, ensuring the smoothness of the rotation process. During the rotation process, the connecting rod 1 5 rotates on the circular shell 1 through the bearing, and the connecting rod 2 6 rotates on the circular shell 1 through the bearing, achieving the effect of the circular shell 1 not moving and driving the rotating center block 7 to rotate.

[0026] like Figure 5 As shown, two rotating shafts 10 are symmetrically positioned at both ends of the alloy mold 9. A mounting plate with a threaded hole is fixedly welded to one end of each rotating shaft 10, and the mounting plate is bolted to the alloy mold 9. A rotating bearing 11 is sleeved on the other end of each rotating shaft 10. The bottom end of the alloy mold 9 is connected to a counterweight 13 via a mounting seat 12. Two mounting seats 12 are provided, symmetrically mounted on the bottom end of the alloy mold 9. A mounting plate is also welded to the top end of each mounting seat 12, and the mounting plate is bolted to the bottom end of the alloy mold 9. Mounting slots are provided on the mounting seats 12, and a slider 14 is provided at the top end of the counterweight seat. The slider 14 is inserted into the slot and slidably connected to the slot. The counterweight 13 can be directly pushed using an existing pushing device, and the slider 14 of the counterweight 13 slides into the slot of the mounting seat 12, completing the installation of the counterweight 13. The presence of friction between the slider 14 and the slot prevents the counterweight 13 from falling off the mounting seat 12.

[0027] A clamping structure for installing an alloy mold 9 is provided on the rotating body 8. The clamping mechanism includes hydraulic cylinders 15 symmetrically arranged on the side surface of the rotating body 8. The hydraulic rod of the hydraulic cylinder 15 is connected to one end of the fixed rod 16, and an arc-shaped clamping seat 17 for clamping the rotating bearing 11 is provided at the other end of the fixed rod 16. A clamping pad 18 is arranged inside the arc-shaped clamping seat 17. The clamping pad 18 is made of rubber material, and a plurality of rubber particles for increasing friction are arranged on the inner side of the clamping pad 18. The hydraulic cylinders 15 at corresponding positions on two adjacent rotating bodies 8 drive the fixed rods 16 to extend simultaneously, and the arc-shaped clamping seats 17 on the two fixed rods 16 cooperate to clamp the rotating bearing 11 on the alloy mold 9. After clamping, the rotating shaft 10 of the alloy mold 9 can rotate around the rotating bearing 11. During the clamping process, the arc-shaped clamping seat 17 presses the clamping pad 18, and the clamping pad 18 deforms and presses the rotating bearing 11, and the two arc-shaped clamping seats 17 cooperate with each other to tightly clamp and fix the rotating bearing 11.

[0028] As Figure 9 , Figure 10 shown, an opening 19 for casting the alloy mold 9 is provided at the top end of the circular shell 1, and an opening 20 for the alloy mold 9 to rise to the rotating mechanism is provided at the bottom end of the circular shell 1. The molten alloy liquid is cast into the alloy mold 9 from the opening 19 at a uniform speed through an existing casting mechanism. The length and width of the opening 20 are both larger than those of the opening 19, and the opening 20 can enable the alloy mold 9 to easily enter the circular shell 1 without being blocked. A lifting mechanism for lifting the alloy mold 9 to the rotating mechanism is arranged below the circular shell 1. As Figure 6 , Figure 7 , Figure 8 shown, the lifting mechanism includes a lifting base 22. The lifting base 22 is arranged below the opening 20 of the circular shell 1, and the lifting base 22 is arranged on the ground. Hydraulic cylinders 21 are symmetrically installed at the top end of the lifting base 22. The hydraulic rod of the hydraulic cylinder 21 is connected to the lifting rod 23, and a lifting seat 24 for placing the rotating shaft 10 is provided at the top end of the lifting rod 23. A groove is arranged inside the lifting seat 24, and the rotating shaft 10 is placed in the groove of the lifting seat 24. The two hydraulic cylinders 21 on the lifting base 22 drive the lifting rod 23 to rise. The rising of the lifting rod 23 drives the lifting seat 24 to rise. When the lifting seat 24 rises, the rotating shaft 10 is clamped into the groove of the lifting seat 24, and the lifting seat 24 continues to rise to lift the rotating shaft 10, thereby driving the alloy mold 9 to rise. The alloy mold 9 enters from the opening 20 and is clamped by the clamping structure after rising to the vacant position of the rotating body 8. An installation groove adapted to the counterweight 13 is arranged on the lifting base 22. The alloy mold 9 can be moved to the lifting base 22 by an existing manipulator, and the counterweight 13 at the bottom of the alloy mold 9 is placed in the installation groove for positioning to ensure that the subsequent hydraulic cylinder drives the lifting seat 24 to lift the rotating shaft 10 of the alloy mold 9.

[0029] As Figure 11 shown, a cooling mechanism is spirally arranged inside the circular housing 1. The cooling mechanism includes a cooling pipe 25 spirally arranged on the inner surface of the circular surface of the circular housing 1. One end of the cooling pipe 25 penetrates through the circular housing 1 and is connected to the refrigeration system. The circular housing 1 is a cylinder as a whole. The other end of the cooling pipe 25 winds inwards from the outermost side of the circular surface of the circular housing 1 and penetrates through the circular surface of the circular housing 1 to be connected to the refrigeration system to form a cycle. A coolant is arranged inside the cooling pipe 25. The cooling pipe 25 is connected to the circular housing 1 through an arc-shaped clamp. The arc-shaped clamp clamps the cooling pipe 25 tightly. Both sides of the arc-shaped clamp are locked and connected to the circular housing 1 through bolts. A plurality of arc-shaped clamps are evenly distributed on the cooling pipe 25 to firmly fix the cooling pipe 25 on the circular housing 1. The refrigeration system adopts an existing structure to cool the coolant through the refrigeration system and convey the coolant to the cooling pipe 25 to finally form a cycle. Through the cooling pipes 25 spirally arranged on both sides inside the circular housing 1, the ferroalloy inside the alloy mold 9 on the entire rotating mechanism is cooled.

[0030] When in use, the operation steps are as follows: Step 1: First, determine the ferroalloy to be cast, and then select the corresponding alloy mold 9 according to different types of ferroalloys.

[0031] Step 2: Install the rotating shaft 10 on both sides of the alloy mold 9, install the mounting seat 12 at the bottom end of the alloy mold 9, and push and install the counterweight 13 to the bottom of the alloy mold 9 through an existing pushing device.

[0032] Step 3: Move the alloy mold 9 to the position of the lifting base 22 of the lifting mechanism through an existing manipulator, and place the counterweight 13 in the installation groove for positioning.

[0033] Step 4: The hydraulic cylinder II 21 drives the lifting rod 23 to rise. The rising of the lifting rod 23 drives the lifting seat 24 to rise. The rising of the lifting seat 24 catches the rotating shaft 10 through the groove, and then the lifting seat 24 continues to rise, driving the alloy mold 9 to enter from the opening II 20 at the bottom of the circular housing 1, so that the alloy mold 9 rises to the vacant position between the rotating bodies 8.

[0034] Step 5: The hydraulic cylinders I 15 at the corresponding positions on two adjacent rotating bodies 8 drive the fixed rods 16 to extend simultaneously. The arc-shaped clamping seats 17 on the two fixed rods 16 jointly clamp the rotating bearing 11 on the alloy mold 9.

[0035] Step 6: The servo motor 4 on the fixed platform I 2 drives the rotation center body to rotate, and then drives the rotating body 8 to rotate, driving the lowermost alloy mold 9 to rotate and rise.

[0036] Step 7: Repeat Steps 2 to 6 to set different types of molds in all six vacant positions.

[0037] Step eight: The servo motor 4 on the fixed table 1 drives one of the alloy molds 9 to rotate and rise to the highest position, and the molten alloy liquid is cast into the alloy mold 9 from the opening 19 at a uniform speed through an existing casting mechanism.

[0038] Step nine: The servo motor 4 drives the alloy mold 9 to rotate slowly at a uniform speed. Under the action of the counterweight 13, the alloy mold 9 rotates through the rotary bearing 11, always maintaining the positions of the top and bottom surfaces unchanged, and hardly shakes during the rotation process.

[0039] Step ten: Repeat step eight and step nine until all the alloy molds 9 are cast. Cool the coolant through an existing refrigeration system, transport it to the cooling pipe 25, and form a cycle. Cool the alloy molds 9 on the entire rotating mechanism through the cooling pipes 25 spirally arranged on both sides inside the circular housing 1.

[0040] Therefore, the present invention adopts the above-mentioned cooling rotary die casting machine and its casting method. The rotation of the alloy mold on the rotating mechanism facilitates continuous casting production. The lifting mechanism can lift different types of alloy molds to the rotating mechanism. During the production process, various types of alloys can be cast, meeting the requirement of casting multiple alloys with the same device.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that they can still modify or equivalently replace the technical solutions of the present invention, and these modifications or equivalent replacements cannot make the modified technical solutions deviate from the spirit and scope of the technical solutions of the present invention.

The molten alloy liquid is cast into the alloy mold from the first opening at a uniform speed through the existing casting mechanism; Step 9, the servo motor drives the alloy mold to rotate at a uniform speed. Under the action of the counterweight, the alloy mold rotates through the rotating bearing to keep the positions of the top and bottom surfaces unchanged; Step 10, repeat Steps 8 and 9 until all the alloy molds are cast. The coolant is conveyed to the cooling pipes, and the alloy molds on the rotating mechanism are cooled through the cooling pipes spirally arranged on both sides inside the circular shell.
