Description

Technical Field

[0001] This utility model relates to the field of casting grinding balls, specifically a novel horizontal centrifugal metal mold grinding ball casting machine. Background Technology

[0002] Grinding balls are grinding media widely used in ball mills in industrial production. Their quality and performance directly affect the working efficiency and service life of the ball mill. Therefore, the requirements for their quality and performance are high. As the demand for grinding balls increases, it has promoted the continuous development and improvement of grinding ball production technology, which has led to the development of centrifugal casting machines.

[0003] In the prior art, patent CN90104290.0 discloses a novel vertical centrifugal metal mold grinding ball casting machine. A motor drives a pallet and a metal mold mounted on the pallet to rotate around the axis of a vertically mounted main shaft via a belt conveyor. The metal mold consists of upper and lower circular templates and upper and lower ball molds fitted onto the upper and lower circular templates. The ball molds are divided into two groups: small ball molds and large ball molds, distributed at equal points on the small and large circumferences of the circular templates, respectively. The pouring section consists of a main gating system, a runner, and inner runners that connect radially to each ball mold and converge on the circumference of the runner. This machine allows the molten iron to solidify first in the ball molds and then in the inner runners, facilitating sufficient feeding and venting, resulting in well-formed grinding balls without porosity or shrinkage cavities, and increasing the single-machine output of grinding balls.

[0004] The centrifugal metal mold grinding ball casting machine provided by the aforementioned patent can ensure unobstructed internal gating and sufficient molten iron feeding through centrifugal force, and can also fully expel air from the molten iron, thereby improving the quality and yield of the grinding balls. However, this device lacks a cooling structure during grinding ball casting, resulting in a slow cooling rate of the grinding balls, which is detrimental to improving the efficiency of grinding ball casting. Furthermore, the mold has a short service life and high manufacturing costs. Opening and closing the mold is also time-consuming and laborious during use. Utility Model Content

[0026] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details:

[0027] Example 1

[0028] like Figure 1 , Figure 2 and Figure 4As shown, a novel horizontal centrifugal metal mold grinding ball casting machine includes a frame 1 and a main shaft 4, which is rotatably mounted on the frame 1. It also includes a motor 2 and a V-belt 20. The motor 2 and a rotating base 3 are arranged side-by-side on the frame 1, and the main shaft 4 is rotatably mounted on the rotating base 3. A first V-belt pulley 201 is mounted on the output shaft of the motor 2, and a second V-belt pulley 401 is mounted on the shaft of the main shaft 4. The first and second V-belt pulleys 201 and 401 are connected by the V-belt 20. A brake valve 19 is also included, located beside the second V-belt pulley 401 on the main shaft 4. The main shaft 4 is driven to rotate by the motor 2, and the brake valve 19 can assist in stopping the rotation of the main shaft 4.

[0029] like Figure 1 , Figure 4 and Figure 5 As shown, the main shaft 4 is a hollow shaft tube with one open end, and a water inlet pipe 14 is provided in the cavity. A water outlet cavity 15 is formed between the inner wall of the main shaft 4 and the water inlet pipe 14. A metal ball mold is provided at the closed end of the main shaft 4, and a rotating joint 16 is provided at the other end. By providing the rotating joint 16, the external water pipe can be prevented from rotating with the main shaft 4. A water inlet connector 1601 and a water outlet connector 1602 are provided on the rotating joint 16. A first water pipe connection valve 17 and a second water pipe connection valve 18 are provided on the shaft body of the main shaft 4. One end of the water inlet pipe 14 is connected to the first water pipe connection valve 17, and the other end is connected to the water inlet connector 1601. The second water pipe connection valve 18 and the water outlet connector 1602 are both connected to the water outlet cavity 15. Then, by connecting the rotary joint 16 and the water inlet pipe 14, external water can be supplied to the water inlet pipe 14 through the rotary joint 16. The internal rotatable connection between the water inlet pipe 14 and the rotary joint 16 ensures that the water inlet pipe 14 does not affect the smooth flow of water when it rotates with the main shaft 4. By setting the water inlet pipe 14 and the water outlet chamber 15 inside the main shaft 4, the water supply structure can rotate with the rotation of the main shaft 4, preventing the external pipeline from getting tangled on the main shaft 4 during rotation.

[0030] like Figure 1 , Figure 3 and Figure 4As shown, the metal ball mold is equipped with an openable first fixing frame 5 and a second fixing frame 7, and multiple openable ball molds 8 are arranged sequentially along their circumferential direction on their opening and closing surfaces. The metal ball mold also includes a feed port 9 and an ingate 21. The feed port 9 is located in the middle of the second fixing frame 7, and the ingate 21 is provided between the ball molds 8 and the feed port 9. The feed port 9 is connected to the inside of the ball mold 8 through the ingate 21. During casting, the ladle is connected to the feed port 9, and the molten iron is injected into each ball mold 8 through each ingate 21. Then, the rotation of the main shaft 4 causes the molten iron to gather on the side of the ball mold 8 away from the center under the action of centrifugal force until it is full. The ladle and the feed port are easily connected, and there is no leakage under centrifugal force. The system also includes a cylinder 6, which is equipped with a telescopic rod 601. The cylinder 6 also includes an inlet valve port 602 and an outlet valve port 603. The hollow shaft of the main shaft 4 also houses an inlet pipe 12 and an outlet pipe 13. An air control valve 22 is rotatably mounted on the shaft of the main shaft 4. The ends of the inlet pipe 12 and the outlet pipe 13 near the air control valve 22 both pass through the main shaft 4 and abut against the valve port of the air control valve 22. The air control valve 22 is connected to an external air supply device and is a sealed rotatable sleeve mounted on the shaft of the main shaft 4. By setting the air control valve 22, the inlet pipe 12 and the outlet pipe 13 can rotate with the main shaft 4 without air supply. When the main shaft 4 stops rotating and the cylinder 6 needs to be started, the inlets of the inlet pipe 12 and the outlet pipe 13 are aligned with the corresponding valve ports of the air control valve, allowing the air pump 6 to operate via an external air source. Furthermore, by rotating the air control valve 22 and the main shaft 4, the rotation of the main shaft 4 prevents the air control valve 22 from rotating, thus avoiding the problem of external air supply lines becoming entangled due to the rotation of the main shaft 4. The end of the air inlet pipe 12 furthest from the air control valve 22 extends through the main shaft 4 to the external connection air inlet valve 602, and the end of the air outlet pipe 13 furthest from the air control valve 22 extends through the main shaft 4 to the external connection air outlet valve 603. One end of the first mounting bracket 5 is fixedly mounted on the closed end of the main shaft 4, and the other end is connected to an openable second mounting bracket 7 via a cylinder 6. Three cylinders 6 are sequentially arranged in a circumferential direction on the end face of the first mounting bracket 5 near the main shaft 4. A telescopic rod 601 passes through the first mounting bracket 5 and is inserted into the second mounting bracket 7, driving the second mounting bracket 7 to move. The use of three cylinders 6 ensures that the second mounting bracket 7 is more stably mounted on the first mounting bracket 5. The second fixing frame 7 is moved by the telescopic rod 601 of the cylinder 6, which can realize the opening and closing of the second fixing frame 7, thereby realizing the opening and closing of the metal ball mold. The ball mold 8 includes a cavity part and a frame and support part. The cavity part is stamped from copper plate, and the frame and support part is made of stainless steel. The cavity part is welded to the frame and support part, which can effectively reduce the mold manufacturing cost.

[0031] like Figure 1 and Figure 5As shown, the first fixing frame 5 and the second fixing frame 7 are respectively provided with a first circulation chamber 10 and a second circulation chamber 11 for wrapping the ball mold 8; the first water pipe connecting valve 17 and the second water pipe connecting valve 18 are both connected to the first circulation chamber 10 and the second circulation chamber 11 through pipelines. The cylinder 6 also includes a through hole 604, which is provided in the middle of the cylinder 6 along its length direction; the cylinder is specially designed and customized, and the through hole 604 is opened in the middle of the cylinder 6 to connect the water channel without affecting the normal operation of the cylinder. The first circulation chamber 10 is provided with a first inlet valve 1001 and a second outlet valve 1102; the second circulation chamber 11 is provided with a second inlet valve 1101 and a second outlet valve 1102; there are two first water pipe connection valves 17, one of which is connected to the first inlet valve 1001 through the through hole 604 of one of the cylinders 6; the other of which is connected to the second inlet valve 1101; there are two second water pipe connection valves 18, one of which is connected to the first inlet valve 1001 through the through hole 604 of one of the cylinders 6, and the other of which is connected to the second outlet valve 1102 through the through hole 604 of one of the cylinders 6. External cooling water is supplied to the first inlet valve 1001 via the inlet pipe 14 of the rotary joint 16, through one of the first water pipe connection valves 17 and the through hole 604 of the cylinder 6 connected thereto, thereby delivering cooling water into the first circulation chamber 10 to cool the ball mold 8. Since the first outlet valve 1002 is located away from the main shaft 4, it is inconvenient to connect it to the second water pipe connection valve 18. Therefore, the first outlet valve 1002 is connected to the second water pipe connection valve 18 through the through hole 604 of one of the cylinders 6, facilitating the return of cooling water to the outlet chamber 15 for circulation and discharge. Simultaneously, external cooling water in the inlet pipe 14 is diverted to the second inlet valve 1101 through another first water pipe connection valve 17, flowing into the second circulation chamber 11 to cool the ball mold 8. Then, the second outlet valve 1102 is connected to the second water pipe connection valve 18 through the through hole 604 of the last cylinder 6, thus discharging the cooling water from the second circulation chamber 11.

[0032] Example 2

[0033] like Figure 1 , Figure 2 and Figure 4 As shown, a novel horizontal centrifugal metal mold grinding ball casting machine includes a frame 1 and a main shaft 4, which is rotatably mounted on the frame 1.

The first and second V-belt pulleys 201 are connected by the V-belt 20. A brake valve 19 is also included, located on the side of the second V-belt pulley 401 on the main shaft 4.

[0034] like Figure 1 , Figure 4 and Figure 5 As shown, the main shaft 4 is a hollow shaft tube with one open end, and a water inlet pipe 14 is provided in the cavity.

[0035] like Figure 1 , Figure 3 and Figure 4 As shown, the metal ball mold is provided with an openable first fixing frame 5 and a second fixing frame 7, and multiple openable ball molds 8 are arranged sequentially along the circumferential direction on their opening and closing surfaces. The metal ball mold also includes a feed port 9 and an inner sprue 21. The feed port 9 is provided at the middle position of the second fixing frame 7. An inner sprue 21 is provided between the ball mold 8 and the feed port 9. The feed port 9 is connected to the inside of the ball mold 8 through the inner sprue 21. Additionally, it includes a cylinder 6, which is equipped with a telescopic rod 601; the cylinder 6 also includes an inlet valve port 602 and an outlet valve port 603; the hollow shaft tube of the main spindle 4 is also equipped with an inlet pipe 12 and an outlet pipe 13; an air control valve 22 is rotatably mounted on the shaft of the main spindle 4; the ends of the inlet pipe 12 and the outlet pipe 13 near the air control valve 22 both pass through the main spindle 4 and abut against the valve port of the air control valve 22; the air control valve 22 is connected to an external air supply device and is sealed and rotatably mounted on the shaft of the main spindle 4. The end of the inlet pipe 12 away from the air control valve 22 passes through the main spindle 4 and extends to the external inlet valve port 602; the end of the outlet pipe 13 away from the air control valve 22 passes through the main spindle 4 and extends to the external outlet valve port 603. One end of the first fixing bracket 5 is fixedly mounted on the closed end of the main spindle 4, and the other end is equipped with an openable and closable second fixing bracket 7 via the cylinder 6. Three cylinders 6 are sequentially arranged in a circumferential direction on the end face of the first fixed frame 5 near the main shaft 4. The telescopic rod 601 passes through the first fixed frame 5 and is inserted into the second fixed frame 7, driving the second fixed frame 7 to move. The ball mold 8 includes a cavity part and a frame and support part. The cavity part is stamped from a copper plate, and the frame and support part are made of stainless steel. The cavity part is welded to the frame and support part, which can effectively reduce the mold manufacturing cost.

[0036] like Figure 1 and Figure 5As shown, the first fixed frame 5 and the second fixed frame 7 are respectively provided with a first circulation chamber 10 and a second circulation chamber 11 for wrapping the ball mold 8; the first water pipe connecting valve 17 and the second water pipe connecting valve 18 are both connected to the first circulation chamber 10 and the second circulation chamber 11 through pipelines. The cylinder 6 also includes a through hole 604, and the cylinder 6 has a through hole 604 that runs through the entire length of its middle part; the first circulation chamber 10 is provided with a first water inlet valve 1001 and a second water outlet valve 1102; the second circulation chamber 11 is provided with a second water inlet valve 1101 and a second water outlet valve 1102; there are two first water pipe connecting valves 17, one of which is connected to the first water inlet valve 1001 through the through hole 604 of one of the cylinders 6; the other is connected to the second water inlet valve 1101; there are two second water pipe connecting valves 18, one of which is connected to the first water inlet valve 1001 through the through hole 604 of one of the cylinders 6, and the other is connected to the second water outlet valve 1102 through the through hole 604 of one of the cylinders 6.

[0037] The working principle of this utility model is as follows: During casting, the ladle is connected to the feed port 9. Molten iron is injected into each ball mold 8 through each inner gating channel 21. Then, the rotation of the main shaft 4 causes the molten iron to gather on the side away from the center of the ball mold 8 under the action of centrifugal force until it is full. The ladle is convenient to connect with the feed port and will not leak under centrifugal force. At the same time, the external cooling water is connected through the water inlet connector 1601 on the rotary joint 16 and flows through the water inlet pipe 14 to the first water pipe connecting valve 17, and is divided into the first circulation chamber 10 and the second circulation chamber 11 to cool the ball mold 8.

Furthermore, the rotating joint 16 on the main shaft 4 prevents the external water supply device from rotating with the main shaft 4, thereby achieving cooling of the rotating metal ball mold, improving the cooling speed of the grinding balls, and effectively improving the efficiency of grinding ball casting. By setting a rotating metal ball mold, during casting, the vehicle-mounted ladle can be connected to the feed port 9, and molten iron can be injected into each ball mold 8 through each ingate 21. Then, the rotation of the main shaft 4 causes the molten iron to gather on the side away from the center of the ball mold 8 under the action of centrifugal force until it is full.

Various modifications and variations can be made to this utility model by those skilled in the art.
