Description

Technical Field

[0001] The present invention relates to the technical field of casting grinding balls, and particularly to a new type of horizontal centrifugal metal mold grinding ball casting machine. Background Art

[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, higher requirements are imposed on their quality and performance. With the increasing demand for grinding balls, it has promoted the continuous development and improvement of grinding ball production technology, thus giving rise to centrifugal casting machines.

[0003] In the prior art, the invention patent with the patent number CN90104290.0 discloses a new type of vertical centrifugal metal mold grinding ball casting machine. The motor drives a tray and a metal mold mounted on the tray to rotate together around the axis of a vertically installed main shaft through a belt transmission mechanism. The metal mold consists of upper and lower circular templates and upper and lower ball molds inserted on the upper and lower circular templates. The ball molds are divided into two groups, small ball molds and large ball molds, which are respectively distributed at the equally divided points on the small circumference and the large circumference of the circular template. The gating system consists of a main runner, a diverter, and ingates that communicate with each ball mold and radially converge on the circumference of the diverter. In this machine, the molten iron solidifies first in the ball mold and then in the ingate, which is beneficial for sufficient feeding and sufficient exhaust, so that the cast grinding balls have a complete appearance, no porosity and shrinkage cavities, and the single-machine output of the grinding balls is increased.

[0026] The following will be further described in conjunction with the drawings and specific embodiments:

[0027] Embodiment 1

[0028] Such as 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, the main shaft 4 is rotatably mounted on the frame 1, and also includes a motor 2 and a V-belt 20. The motor 2 and the rotating seat 3 are arranged in parallel on the frame 1, and the main shaft 4 is rotatably arranged on the rotating seat 3; a first V-belt pulley 201 is arranged on the output shaft of the motor 2, and a second V-belt pulley 401 is arranged on the shaft body of the main shaft 4, and the first V-belt pulley 201 and the second V-belt pulley 401 are connected by the V-belt 20. In addition, a brake valve 19 is also included, and the brake valve 19 is arranged on the side of the main shaft 4 at the second V-belt pulley 401. The main shaft 4 is driven to rotate by the motor 2, and then the brake valve 19 is arranged to assist the main shaft 4 to stop rotating.

[0029] like Figure 1 , Figure 4 and Figure 5 As shown, the main shaft 4 is a hollow shaft tube with one end open, and a water inlet pipe 14 is arranged in the cavity, and 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 arranged at the closed end of the main shaft 4, and a rotating joint 16 is rotatably arranged at the other end; by setting the rotating joint 16, the external water pipe can be prevented from rotating with the main shaft 4. A water inlet joint 1601 and a water outlet joint 1602 are arranged on the rotating joint 16, and a first water pipe connecting valve 17 and a second water pipe connecting valve 18 are arranged on the shaft body of the main shaft 4. One end of the water inlet pipe 14 is connected to the first water pipe connecting valve 17, and the other end is connected to the water inlet joint 1601, and the second water pipe connecting valve 18 and the water outlet joint 1602 are both connected to the water outlet cavity 15. Then, the rotating joint 16 and the water inlet pipe 14 are abutted, and the external water source can be transported to the water inlet pipe 14 through the rotating joint 16, and the water inlet pipe 14 and the rotating joint 16 are internally rotatingly connected, so that the water inlet pipe 14 does not affect the smooth flow of water when it rotates with the main shaft 4. By arranging the water inlet pipe 14 and the water outlet cavity 15 inside the main shaft 4, the water supply structure can rotate with the rotation of the main shaft 4, and the external pipe line can be prevented from being entangled on the main shaft 4 during the rotation of the main shaft 4.

[0030] like Figure 1 , Figure 3 and Figure 4As shown in the figure, a first fixed frame 5 and a second fixed frame 7 that can be opened and closed are provided in the metal ball mold, and a plurality of ball molds 8 that can be opened and closed are sequentially arranged along the circumferential direction on the opening and closing surface. The metal ball mold further includes a feed inlet 9 and an internal runner 21. A feed inlet 9 is provided at the middle position of the second fixed frame 7. An internal runner 21 is provided between the ball mold 8 and the feed inlet 9. The feed inlet 9 is connected to the inside of the ball mold 8 through the internal runner 21. During casting, the vehicle-mounted ladle is connected to the feed inlet 9, and the molten iron passes through each internal runner 21 and is injected into each ball mold 8. Then, by rotating the main shaft 4, the molten iron gathers on the side away from the center of the circle in the ball mold 8 under the action of centrifugal force until it is full. The connection between the vehicle-mounted ladle and the feed inlet is convenient, and there is no leakage under the centrifugal action. Additionally, it further includes a cylinder 6, and a telescopic rod 601 is provided on the cylinder 6; the cylinder 6 further includes an air inlet valve port 602 and an air outlet valve port 603; an air inlet pipe 12 and an air outlet pipe 13 are further provided inside the hollow shaft tube of the main shaft 4. An air control valve 22 is rotatably installed on the shaft body of the main shaft 4. One ends of the air inlet pipe 12 and the air outlet pipe 13 close to the air control valve 22 penetrate through the main shaft 4 and abut against the valve ports of the air control valve 22; the air control valve 22 is connected to an external air supply device and is hermetically and rotatably sleeved on the shaft body of the main shaft 4. By providing the air control valve 22, the air inlet pipe 12 and the air outlet pipe 13 can rotate following the main shaft 4 when not ventilated. When the main shaft 4 stops rotating and the cylinder 6 needs to be started, the pipe orifices of the air inlet pipe 12 and the air outlet pipe 13 are aligned with the corresponding valve ports of the air control valve, and the air pump 6 can be driven to work through the external air source. And through the rotational setting of the air control valve 22 and the main shaft 4, the main shaft 4 will not drive the air control valve 22 to rotate during the rotation process, thereby avoiding the problem of the pipeline of the external air source following the main shaft 4 to rotate and causing the pipeline to be entangled. One end of the air inlet pipe 12 away from the air control valve 22 penetrates through the main shaft 4 and extends to the outside to connect to the air inlet valve port 602, and one end of the air outlet pipe 13 away from the air control valve 22 penetrates through the main shaft 4 and extends to the outside to connect to the air outlet valve port 603. One end of the first fixed frame 5 is fixedly provided on the closed end of the main shaft 4, and the other end is provided with a second fixed frame 7 that can be opened and closed through the cylinder 6. Three cylinders 6 are sequentially arranged along the circumferential direction on the end surface of the first fixed frame 5 close to the main shaft 4. The telescopic rod 601 penetrates through the first fixed frame 5 and is inserted on the second fixed frame 7, and drives the second fixed frame 7 to move. By providing three cylinders 6, the second fixed frame 7 can be more stably installed on the first fixed frame 5. The second fixed frame 7 is driven to move through the telescopic rod 601 of the cylinder 6, and the opening and closing of the second fixed frame 7 can be realized, thereby realizing the mold opening and mold closing of the metal ball mold. The ball mold 8 includes a cavity part, a frame and a support part. The cavity part is formed by stamping a copper plate, and the frame and the support part are made of stainless steel. The cavity part is welded to the frame and the support part, which can effectively reduce the mold manufacturing cost.

[0031] As Figure 1 and Figure 5As shown, the first and second fixing frames 5 and 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 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 middle part of the cylinder 6 is provided with a through hole 604 that penetrates the whole along its length direction; the cylinder is specially designed and customized, and a through hole 604 is opened in the middle part of the cylinder 6 without affecting the normal operation of the cylinder, for connecting the waterway. The first circulation chamber 10 is provided with a first water inlet valve 1001 and a first water inlet valve 1001; the second circulation chamber 11 is provided with a second water inlet valve 1101 and a second water outlet valve 1102; two first water pipe connecting valves 17 are provided, one first water pipe connecting valve 17 is connected to the first water inlet valve 1001 through the through hole 604 of one of the cylinders 6; the other first water pipe connecting valve 17 is connected to the second water inlet valve 1101; two second water pipe connecting valves 18 are provided, one 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. The external cooling water is connected to the first water inlet valve 1001 through the water inlet pipe 14 of the rotary joint 16, through one of the first water pipe connecting valves 17 and the through hole 604 of the cylinder 6 connected thereto, so that the cooling water is transported to the inside of the first circulation chamber 10 to cool the ball mold 8. At the same time, since the first water outlet valve 1002 is located at the end away from the main shaft 4, it is inconvenient to connect with the second water pipe connecting valve 18, so the first water outlet valve 1002 is connected to the second water pipe connecting valve 18 through the through hole 604 of one of the cylinders 6, so that the cooling water can be easily returned to the water outlet chamber 15 for circulation and discharge. At the same time, the external cooling water is diverted to the second water inlet valve 1101 through another first water pipe connecting valve 17 in the water inlet pipe 14, flows into the second circulation chamber 11 to cool the ball mold 8, and then the second water outlet valve 1102 is connected to the second water pipe connecting valve 18 through the through hole 604 of the last cylinder 6, so that the cooling water in the second circulation chamber 11 is discharged.
