[0017] A process for manufacturing a track roller, using the above-mentioned track roller manufacturing equipment, comprises the following steps:

[0018] S1: first insert the lower mold into the placement groove, place the upper mold on the lower mold for mold closing and fix the threaded joint with the threaded tube, then, through the second moving module, the second moving plate is moved in the direction close to the fixed plate, and at the same time, the moving frame is pushed upward by the rotating tube, the sleeve rod and the third connecting block, so that the second pushing rod slides downward along the second inclined groove, thereby driving the first L-shaped plate to move in the direction close to the sand casting mold body through the moving block and the L-shaped block, and at the same time, the fifth spring is compressed, so that the inclined surface is against the four top edges of the upper mold, which can push the upper mold to be centered and adjusted, and push it to move downward and against the lower mold, and after the upper mold and the lower mold are against each other, when the second moving plate continues to move, the sliding plate can be moved downward along the rotating tube, and at the same time, the fourth spring is compressed, at this time, it can provide pre-tightening force between the upper mold and the lower mold, so that the cooperation between the upper mold and the lower mold is tighter and more reliable, thereby ensuring the quality of subsequent casting;

[0019] S2: When the supporting wheel is being cast, when the second movable plate moves toward the direction close to the fixed plate, the sliding block is driven to move away from the fixed cover through the first connecting block. At this time, negative pressure is generated in the fixed cover. At the same time, when the first L-shaped plate moves toward the direction close to the sand casting mold body and abuts the lower mold against the upper mold, the sealing plate can be driven to move to the top of the riser through the second L-shaped frame to form a sealing effect. Then, the molten metal is poured into the heat preservation box, and the cover plate is rotated and closed by the rotating module, so as to seal the heat preservation box;

[0020] S3: Next, the first solenoid valve and the second solenoid valve are opened. At this time, the gas inside the sand casting mold body can be sucked into the fixed cover through the first exhaust pipe. At the same time, the gas in the heat preservation box can be absorbed to form a negative pressure inside the heat preservation box, so as to facilitate the discharge of the gas in the molten metal, avoid the generation of bubbles during the molding of the supporting roller, and ensure the casting quality of the supporting roller;

[0021] S4: When the exhaust mechanism is exhausting the heat preservation box, the motor is started, and the rotation of the motor drives the rotation of the winding wheel, so that the pull rope can be reeled in, and then the first moving plate and the scraper are pulled to move in the direction close to the slag outlet, and at the same time, the first T-shaped guide rod is driven to move, and the second spring is compressed. At this time, the scraper can scrape and clean the slag on the surface of the molten metal, and scrape it to the side close to the slag outlet, so that the slag is between the scraper and the heat preservation box. At this time, the motor is stopped;

[0022] S5: When scraping and cleaning the slag, the first moving plate and the scraper are moved by the moving mechanism. At the same time, when the first moving plate moves, the rotating rod and the stirring rod can be driven to move synchronously through the first mounting block. At the same time, when the upper end of the first moving rod abuts against the side wall of the projection, the first pushing block can be pushed to move downward. At this time, the first pushing rod slides upward along the first inclined groove, so that the rack can be pushed to move through the second connecting block. At the same time, the third spring is compressed. When the upper end of the first moving rod passes over the side wall of the projection, the rack can be moved and reset under the action of the third spring. This reciprocating process can make the rack move back and forth, thereby driving the gear to reciprocate, and then driving the rotating rod and the stirring rod to reciprocate, so that the molten metal can be reciprocated and stirred before pouring, which not only makes the molten metal more uniform, but also facilitates the discharge of gas in the molten metal, thereby improving the casting quality of the supporting wheel;

[0023] S6: Then, the first closing plate is driven to open through the first moving module, so that the molten metal in the insulation box can pass through the high-temperature resistant metal hose, the connecting pipe, the threaded joint and the threaded pipe and then enter the sand casting mold body through the gate for sand casting, thereby ensuring the quality of the casting. At the same time, when the first closing plate is moved and opened, the triangular block is driven to move through the second L-shaped plate. When the triangular block abuts against the end of the knocking rod, the knocking rod can be pushed to move in the direction close to the second moving module. At the same time, the first spring is compressed. When the triangular block passes over the end of the knocking rod, the knocking rod can move and reset under the action of the first spring. In this way, the side wall of the first moving plate can be reciprocated and knocked and vibrated, and the vibration can be transmitted to the slag through the scraper, thereby facilitating the vibration and separation of the molten metal remaining on the surface of the slag, thereby avoiding the waste of molten metal.

[0024] S7: After the pouring is completed, the motor can be started again, and the first moving plate and the scraper are pulled forward for a distance by the pull rope, so that the lower end of the scraper moves into the slag outlet. At the same time, when the first moving plate continues to move, it can drive the second moving rod to move synchronously. At this time, the end of the second moving rod is against the side wall of the inclined plate, so that the connecting plate can be pushed upward. At the same time, the sixth spring is compressed and drives the second sealing plate to move upward synchronously, so as to open the slag outlet. At this time, the slag can slide through the slag outlet into the collecting trough for collection, so as to facilitate the automatic collection of the scraped slag, which is more convenient and quick to use.

[0025] S8: Then, the motor is started to reverse, and under the action of the second spring, the first moving plate and the scraper are moved and reset, and at the same time, the second sealing plate can be moved upward and reset under the action of the sixth spring, so as to seal the slag outlet. At the same time, the first moving module drives the first sealing plate to move and reset, and the bottom of the heat preservation box is sealed, and the cover plate is driven to rotate and open by the rotating module, so as to continue casting later;

[0026] S9: After the casting is completed, the second movable plate is driven by the fixed plate to move and reset. At this time, under the action of the fifth spring, the first L-shaped plate is moved and reset, thereby loosening the upper mold. At this time, the supporting wheel after sand casting can be taken out from the sand casting mold body. At the same time, the sliding block is driven to move into the fixed cover to squeeze the gas in the fixed cover. At the same time, the first one-way valve is opened, and the second one-way valve and the third one-way valve are closed, so that the gas in the fixed cover can be squeezed out through the outlet pipe.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] (1) The supporting wheel manufacturing equipment and the supporting wheel manufacturing process, by setting a limit mechanism, etc., when casting the supporting wheel, first the lower mold is inserted into the placement groove, and the upper mold is placed on the lower mold for mold closing, then the second moving plate is moved in the direction close to the fixed plate by the second moving module, and at the same time, the moving frame is pushed to move upward by the rotating tube, the sleeve rod and the third connecting block, so that the second push rod slides downward along the second inclined groove, thereby driving the first L-shaped plate to move in the direction close to the sand casting mold body through the moving block and the L-shaped block, and at the same time, the fifth spring is compressed, so that the inclined surface is abutted against the four top edges of the upper mold, which can push the upper mold to be centered and adjusted, and push it to move downward and abut against the lower mold, and after the upper mold and the lower mold are abutted, when the second moving plate continues to move, the sliding plate can be moved downward along the rotating tube, and at the same time, the fourth spring is compressed, at this time, it can provide a pre-tightening force between the upper mold and the lower mold, so that the cooperation between the upper mold and the lower mold is tighter and more reliable, thereby ensuring the quality of subsequent casting.

[0029] (2) The supporting roller manufacturing equipment and the supporting roller manufacturing process are provided with an exhaust mechanism, etc., so that when the supporting roller is cast, when the second movable plate moves toward the direction close to the fixed plate, the sliding block is driven to move away from the fixed cover through the first connecting block, and at the same time, the first one-way valve is closed. At this time, negative pressure is generated in the fixed cover. At the same time, when the first L-shaped plate moves toward the direction close to the sand casting mold body and abuts the lower mold and the upper mold, at this time, the sealing plate can be driven by the second L-shaped frame to move to the top of the riser and form a sealing effect. Then, the molten metal is poured into the heat preservation box, and the cover plate is rotated and closed by the rotating module to seal the heat preservation box. Then, the first solenoid valve and the second solenoid valve are opened. At this time, the gas inside the sand casting mold body can be sucked into the fixed cover through the first exhaust pipe. At the same time, the gas in the heat preservation box can be absorbed to form a negative pressure inside the heat preservation box, so that the gas in the molten metal can be discharged easily, bubbles can be avoided during the forming of the supporting roller, and the quality of the supporting roller casting can be ensured.

[0030] (3) The supporting wheel manufacturing equipment and supporting wheel manufacturing process are provided with a scraping mechanism and a vibrating mechanism, etc. When the exhaust mechanism exhausts the heat preservation box, the motor is started, and the rotation of the motor drives the rotation of the winding wheel, so that the pull rope can be reeled in, and then the first moving plate and the scraper are pulled to move in the direction close to the slag outlet, and at the same time, the first T-shaped guide rod is driven to move, and the second spring is compressed. At this time, the scraper can scrape and clean the slag on the surface of the molten metal, and scrape it to the side close to the slag outlet, so that the slag is between the scraper and the heat preservation box. At this time, the motor is stopped, and then the first moving module drives the first sealing plate to open, so that the molten metal in the heat preservation box can pass through the high-temperature resistant metal hose, the connecting pipe, the threaded joint and the threaded pipe and then enter the sand casting mold body through the gate for sand casting, thereby ensuring the quality of the casting. At the same time, when the first sealing plate moves and opens, the second L-shaped plate drives the triangular block to move. When the triangular block abuts against the end of the knocking rod, the knocking rod can be pushed to the side close to the slag outlet. When the first moving plate is moved forward, the end of the second moving rod is pressed against the side wall of the inclined plate, thereby pushing the connecting plate upward. At the same time, the sixth spring is compressed and drives the second sealing plate to move upward synchronously, thereby opening the slag outlet. At this time, the slag can slide through the slag outlet to the collecting trough for collection, thereby facilitating the automatic collection of the scraped slag, which is more convenient and quicker to use.

[0031] (4) The supporting wheel manufacturing equipment and the supporting wheel manufacturing process are provided with a stirring mechanism, etc., so that when the slag is scraped and cleaned, the first moving plate and the scraper are moved by the moving mechanism. At the same time, when the first moving plate moves, the rotating rod and the stirring rod can be driven to move synchronously through the first mounting block. At the same time, when the upper end of the first moving rod abuts against the side wall of the protrusion, the first pushing block can be pushed to move downward. At this time, the first pushing rod slides upward along the first inclined groove, so that the rack can be pushed to move through the second connecting block. At the same time, the third spring is compressed. When the upper end of the first moving rod passes over the side wall of the protrusion, the rack can be moved and reset under the action of the third spring. In this way, the rack can be reciprocated, thereby driving the gear to reciprocate, and then driving the rotating rod and the stirring rod to reciprocate, so that the molten metal can be reciprocated and stirred before pouring, which not only makes the molten metal more uniform, but also facilitates the discharge of gas in the molten metal, thereby improving the casting quality of the supporting wheel.

[0060] A process for manufacturing a track roller, using the above-mentioned track roller manufacturing equipment, comprises the following steps:

[0061] S1: First, insert the lower mold 1001 into the placement groove 26, place the upper mold 1002 on the lower mold 1001 to close the mold and fix the threaded joint 19 and the threaded tube 20.

[0062] S2: When the supporting wheel is being cast, when the second movable plate 2205 moves toward the direction close to the fixed plate 2203, the sliding block 2202 is driven to move away from the fixed cover 2201 through the first connecting block 2206. At this time, negative pressure is generated in the fixed cover 2201. At the same time, when the first L-shaped plate 2303 moves toward the direction close to the sand casting mold body 10 and abuts the lower mold 1001 and the upper mold 1002, the sealing plate 2213 can be driven by the second L-shaped frame 2210 to move to the top of the riser 1004 and form a sealing effect. Then, the molten metal is poured into the heat preservation box 13, and the cover plate 14 is rotated and closed by the rotating module 24, so as to seal the heat preservation box 13;

[0063] S3: Next, the first solenoid valve 2208 and the second solenoid valve 2211 are opened. At this time, the gas inside the sand casting mold body 10 can be sucked into the fixed cover 2201 through the first exhaust pipe 2209.

[0066] S6: Then, the first closing plate 15 is driven to open through the first moving module 16, so that the molten metal in the insulation box 13 can pass through the high temperature resistant metal hose 17, the connecting pipe 18, the threaded joint 19 and the threaded pipe 20 and then enter the sand casting mold body 10 through the gate 1003 for sand casting to ensure the quality of the casting.

At the same time, the first spring 205 is compressed. When the triangular block 202 passes over the end of the knocking rod 203, the knocking rod 203 can move and reset under the action of the first spring 205. In this way, the side wall of the first moving plate 2104 can be reciprocated and knocked and vibrated, and the vibration is transmitted to the slag through the scraper 2105, so as to facilitate the vibration and separation of the molten metal remaining on the surface of the slag to avoid the waste of molten metal.

[0067] S7: After the pouring is completed, the motor 303 can be started again, and the first moving plate 2104 and the scraper 2105 are pulled forward for a distance by the pull rope 305, so that the lower end of the scraper 2105 moves to the slag outlet 2102. At the same time, when the first moving plate 2104 continues to move, it can drive the second moving rod 805 to move synchronously. At this time, the end of the second moving rod 805 is against the side wall of the inclined plate 807, so that the connecting plate 803 can be pushed to move upward. At the same time, the sixth spring 804 is compressed and drives the second sealing plate 2103 to move upward synchronously, thereby opening the slag outlet 2102. At this time, the slag can slide through the slag outlet 2102 to the collecting trough 2101 for collection, so as to facilitate the automatic collection of the scraped slag, which is more convenient and quick to use.

[0068] S8: Then, the motor 303 is started to reverse, and under the action of the second spring 307, the first movable plate 2104 and the scraper 2105 are moved and reset. At the same time, the second sealing plate 2103 can be moved upward and reset under the action of the sixth spring 804, so as to seal the slag outlet 2102. At the same time, the first sealing plate 15 is driven to move and reset through the first movable module 16, and the bottom of the heat preservation box 13 is sealed. In addition, the cover plate 14 is driven to rotate and open through the rotating module 24, so as to continue casting later.

[0069] S9: After the casting is completed, the second movable plate 2205 is moved and reset by the fixed plate 2203. At this time, under the action of the fifth spring 503, the first L-shaped plate 2303 is moved and reset, thereby loosening the upper mold 1002. At this time, the supporting wheel after sand casting can be taken out from the sand casting mold body 10. At the same time, the sliding block 2202 is driven to move into the fixed cover 2201, which can squeeze the gas in the fixed cover 2201. At the same time, the first one-way valve is opened, and the second one-way valve and the third one-way valve are closed, so that the gas in the fixed cover 2201 can be squeezed out through the outlet pipe 2207.

10. A process for manufacturing a track roller, using the track roller manufacturing device according to claim 9, characterized in that: The following steps are involved: S1: First, insert the lower mold (1001) into the placement groove (26), place the upper mold (1002) on the lower mold (1001) to close the mold and fix the threaded joint (19) and the threaded tube (20), then, through the second moving module (2204), the second moving plate (2205) is moved in a direction close to the fixed plate (2203), and at the same time, the moving frame (901) is pushed to move upward by the rotating tube (910) and the sleeve rod (912) and the third connecting block (909), so that the second pushing rod (907) slides downward along the second inclined groove (906), thereby driving the first L-shaped plate (2303) to move close to the sand casting mold body (1006) through the moving block (2301) and the L-shaped block (2302). ), and at the same time, the fifth spring (503) is compressed, so that the inclined surface (2304) abuts against the four top edges of the upper die (1002), which can push the upper die (1002) to be centered and pushed to move downward and abut against the lower die (1001). Moreover, after the upper die (1002) abuts against the lower die (1001), when the second movable plate (2205) continues to move, the sliding plate (911) can move downward along the rotating tube (910). At the same time, the fourth spring (913) is compressed. At this time, a pre-tightening force can be provided between the upper die (1002) and the lower die (1001), so that the upper die (1002) and the lower die (1001) can be matched more tightly and reliably, thereby ensuring the quality of subsequent casting; S2: When the supporting wheel is being cast, when the second movable plate (2205) moves in a direction close to the fixed plate (2203), the sliding block (2202) is driven to move in a direction away from the fixed cover (2201) through the first connecting block (2206). At this time, negative pressure is generated in the fixed cover (2201). At the same time, when the first L-shaped plate (2303) moves in a direction close to the sand casting mold body (10) and abuts the lower mold (1001) and the upper mold (1002), the sealing plate (2213) can be driven to move to the top of the riser (1004) through the second L-shaped frame (2210) to form a sealing effect. Then, the molten metal is poured into the heat preservation box (13), and the cover plate (14) is rotated and closed by the rotating module (24), thereby sealing the heat preservation box (13); S3: Next, the first solenoid valve (2208) and the second solenoid valve (2211) are opened. At this time, the gas inside the sand casting mold body (10) can be sucked into the fixed cover (2201) through the first exhaust pipe (2209). At the same time, the gas inside the heat preservation box (13) can be absorbed to form a negative pressure inside the heat preservation box, thereby facilitating the discharge of the gas in the molten metal, avoiding the generation of bubbles during the molding of the roller, and ensuring the casting quality of the roller; S4: When the exhaust mechanism (22) is exhausting the heat preservation box (13), the motor (303) is started, and the rotation of the motor (303) drives the rotation of the winding wheel (304), so that the pull rope (305) can be reeled in, thereby pulling the first movable plate (2104) and the scraper (2105) to move in a direction close to the slag outlet (2102), and at the same time, the first T-shaped guide rod (306) is driven to move, and the second spring (307) is compressed. At this time, the scraper (2105) can scrape and clean the slag on the surface of the molten metal, and scrape it to the side close to the slag outlet (2102), so that the slag is between the scraper (2105) and the heat preservation box (13). At this time, the motor (303) is stopped; S5: When scraping and cleaning the slag, the first movable plate (2104) and the scraper (2105) are moved by the moving mechanism (3). At the same time, when the first movable plate (2104) moves, the rotating rod (402) and the stirring rod (403) can be driven to move synchronously through the first mounting block (401). At the same time, when the upper end of the first movable rod (704) abuts against the side wall of the protrusion (707), the first pushing block (705) can be pushed to move downward. At this time, the first pushing rod (702) slides upward along the first inclined groove (706), so that the rack (403) can be pushed through the second connecting block (701). The first moving rod (406) is moved, and at the same time, the third spring (604) is compressed. When the upper end of the first moving rod (704) passes over the side wall of the protrusion (707), the rack (406) can be moved and reset under the action of the third spring (604). In this way, the rack (406) can be reciprocated, thereby driving the gear (404) to rotate reciprocatingly, and then driving the rotating rod (402) and the stirring rod (403) to rotate reciprocatingly, so that the molten metal can be reciprocated and stirred before pouring, which not only makes the molten metal more uniform, but also facilitates the discharge of gas in the molten metal, thereby improving the casting quality of the supporting wheel; S6: Then, the first closing plate (15) is driven to open by the first moving module (16), so that the molten metal in the heat preservation box (13) can pass through the high temperature resistant metal hose (17), the connecting pipe (18), the threaded joint (19) and the threaded pipe (20) and then enter the sand casting mold body (10) through the gate (1003) for sand casting, thereby ensuring the quality of the casting. At the same time, when the first closing plate (15) is moved and opened, the triangular block (202) is driven to move by the second L-shaped plate (201). When the triangular block (202) and the knocking rod (203) are in contact with each other, the triangular block (202) and the knocking rod (203) are moved. When the ends abut against each other, the knocking rod (203) can be pushed to move in a direction close to the second moving module (2204). At the same time, the first spring (205) is compressed. When the triangular block (202) passes over the end of the knocking rod (203), the knocking rod (203) can be moved and reset under the action of the first spring (205). In this way, the side wall of the first moving plate (2104) can be knocked and vibrated back and forth, and the vibration is transmitted to the slag through the scraper (2105), so that the molten metal remaining on the surface of the slag can be vibrated and separated, thereby avoiding waste of the molten metal. S7: After the pouring is completed, the motor (303) is started again, and the first movable plate (2104) and the scraper (2105) are pulled forward for a distance by the pull rope (305), so that the lower end of the scraper (2105) moves into the slag outlet (2102). At the same time, when the first movable plate (2104) continues to move, it can drive the second movable rod (805) to move synchronously. At this time, the end of the second movable rod (805) is abutted against the side wall of the inclined plate (807), so that the connecting plate (803) can be pushed to move upward. At the same time, the sixth spring (804) is compressed and drives the second sealing plate (2103) to move upward synchronously, thereby opening the slag outlet (2102). At this time, the slag can slide through the slag outlet (2102) into the collecting trough (2101) for collection, thereby facilitating the automatic collection of the scraped slag, which is more convenient and quick to use; S8: Next, the motor (303) is started to rotate in the reverse direction. Under the action of the second spring (307), the first movable plate (2104) and the scraper (2105) are moved and reset. At the same time, the second sealing plate (2103) is able to move upward and reset under the action of the sixth spring (804), thereby sealing the slag outlet (2102). At the same time, the first movable module (16) drives the first sealing plate (15) to move and reset, and seals the bottom of the heat preservation box (13). In addition, the cover plate (14) is driven to rotate and open through the rotating module (24) so ​​as to continue casting. S9: After the casting is completed, the second movable plate (2205) is moved and reset by the fixed plate (2203). At this time, under the action of the fifth spring (503), the first L-shaped plate (2303) is moved and reset, thereby loosening the upper mold (1002). At this time, the supporting roller after sand casting can be taken out from the sand casting mold body (10). At the same time, the sliding block (2202) is driven to move into the fixed cover (2201), which can squeeze the gas in the fixed cover (2201). At the same time, the first one-way valve is opened, and the second one-way valve and the third one-way valve are closed, so that the gas in the fixed cover (2201) can be squeezed out through the outlet pipe (2207).
