Description

Technical Field

[0001] The invention relates to the technical field of metal casting equipment, and in particular to a metal casting equipment. Background Art

[0002] Metal casting is forging and smelting casting. Smelting casting is the process of melting metal into a liquid that meets certain requirements and pouring it into a mold. After cooling, solidification and cleaning, a casting with a predetermined shape, size and performance is obtained. The casting blank is almost formed, so it can achieve the purpose of no mechanical processing or a small amount of processing, which reduces the cost and time to a certain extent. Casting is one of the basic processes in the modern machinery manufacturing industry. Forging is a processing method that uses forging machinery to apply pressure to metal billets to make them plastically deform to obtain forgings with certain mechanical properties, shapes and sizes. It is one of the two major components of forging (forging and stamping). Forging can eliminate defects such as loose casting produced by the metal in the smelting process, optimize the microstructure, and at the same time, because the complete metal flow line is preserved, the mechanical properties of forgings are generally better than those of castings of the same material. Important parts with high loads and severe working conditions in related machinery, except for simpler shapes that can be rolled plates, profiles or welded parts, are mostly forgings.

[0003] Currently, during metal forging, the metal is hammered after calcining to remove internal impurities. When the metal is mechanically forged in a red-hot state, impurities will fall off the metal surface. These high-temperature impurities will fall to the ground at will, causing workers to step on them by mistake, which may cause the risk of burns. Therefore, we need a metal casting equipment.

At the top of the connecting rod 13, the expansion plate 4 will block the sputtering sparks when in use, and part of them will fall into the inside of the collecting tank 3, and the other part will adhere to the arc-shaped inner wall of the expansion plate 4. Since the expansion plate 4 and the connecting rod 13 are rotatably installed, the expansion plate 4 can be rotated when there is a lot of attached metal slag, and the rotating expansion plate 4 will be dislocated with the connecting rod 13, so that the inclined rod 22 will also be rotationally dislocated with the expansion plate 4, and the metal residue adhered to the inner surface will be scraped off and fall to the inner wall of the collecting tank 3.

And drive the gear ring 14 and the connecting rod 13 to rotate on the slide rail 23, thereby driving the scraper plate body 6 to rotate.

[0033] Reference Figure 6 , Figure 7 The transmission mechanism includes a second slide rail 26, and two sliders 27 are slidably installed on one side of the second slide rail 26 close to the collecting tank 3, and a rotatable linkage rod 25 is installed between the two sliders 27 through a shaft column, and a plug hole is opened at the front end of the top of the linkage rod 25, and the plug hole of the linkage rod 25 is sleeved on the circumferential outer wall of the sleeve shaft 24, and the front end of the linkage rod 25 is sleeved on the circumferential outer wall of the sleeve shaft 24. When the sleeve shaft 24 moves in a circular trajectory on the gear plate 9, it will push the two sliders 27 at the rear end of the linkage rod 25 to move back and forth on the second slide rail 26.

[0034] Reference Figure 4 The rear ends of the two sliders 27 are welded and fixed with the same connecting block 28, and the rear end of the connecting block 28 is welded and fixed with a pushing movement rod 29. The pushing movement rod 29 is fixed to the rear ends of the two sliders 27 through the connecting block 28, so it will be driven by it to move forward and backward.

[0035] Reference Figure 4 , Figure 6 The pressure mechanism includes a pressure gas cylinder 18, and the pressure gas cylinder 18 is detachably mounted on the rear end of the mounting plate 2 close to the rectangular plate 19 by bolts. A rubber piston block 30 is arranged on the inner wall of the pressure gas cylinder 18, and the middle part of the front end of the rubber piston block 30 is fixedly connected to the rear end of the pushing movement rod 29, and the rear end of the pressure gas cylinder 18 is penetrated and connected with a connecting pipe 17, and a one-way valve is arranged inside the connecting pipe 17.

At the same time, a one-way valve is arranged inside the connecting pipe 17, and the internal gas can only flow to the inside of the pressure gas cylinder 18, forming an extraction effect.

[0036] Reference Figure 2 , Figure 3 , Figure 5 The air suction mechanism includes a rectangular rod 8, and the rectangular rod 8 is detachably mounted on the side of the rectangular plate 19 away from the slide rail 26 by bolts, and the side of the rectangular rod 8 away from the rectangular plate 19 is detachably mounted with an arc-shaped air suction box 7 by bolts, and the top of the arc-shaped inner wall of the arc-shaped air suction box 7 is fixed with an air suction groove 20 by bolts, and the air suction groove 20 is connected with the arc-shaped air suction box 7 through a connecting pipe 17, and is connected to the inside of the arc-shaped air suction box 7. When extracting, the arc-shaped air suction box 7 will suck in the smoke generated during forging through the air suction groove 20, and enter the inside of the pressure gas cylinder 18, and be discharged through another pipe body with a built-in one-way valve.

[0037] Reference Figure 1 A discharge groove 16 is welded and fixed to the outside of the rectangular discharge hole at the bottom of the mounting plate 2, and a base plate 12 is welded and fixed to the bottom of the support column 1. By arranging the discharge groove 16 below the rectangular discharge hole, it is convenient for the scraper body 6 to push the impurities entering the rectangular discharge hole to slide into the collection container through the discharge groove 16 to avoid falling directly to the ground.

[0038] When in use, firstly, the calcined metal block is mechanically lifted to the top of the base layer 5 at the top of the support column 1, and the forging operation is performed by the machine. During forging, the impurities falling off the surface of the metal block will fall into the collecting tank 3 below the surrounding area. When the servo motor 10 is running, the output shaft will be used to drive the gear plate 9 to rotate. The rotation of the gear plate 9 will engage the gear ring 14. And it will drive the gear ring 14 and the connecting rod 13 to rotate on the slide rail 23, thereby driving the scraper plate 6 to rotate. When the scraper plate 6 moves in a circular trajectory, it will push the impurity layer that falls to the inner wall of the collecting tank 3 to move. When it moves to the rectangular discharge hole, it will directly fall onto the discharge tank 16, which is convenient for centralized collection and processing. At the same time, the expansion plate 4 will block the sputtering sparks, part of which will fall into the inside of the collecting tank 3, and the other part will adhere to the arc-shaped inner wall of the expansion plate 4. Since the expansion plate 4 and the connecting rod 13 are rotatably installed, the expansion plate 4 can be rotated when there is a lot of attached metal slag, and the rotating expansion plate 4 will be dislocated with the connecting rod 13 , so that the inclined rod 22 will also form a rotational dislocation with the expansion plate 4, scraping off the metal residues adhering to the inner surface and dropping them onto the inner wall of the collecting tank 3. At the same time, the front end of the linkage rod 25 is sleeved on the circumferential outer wall of the sleeve shaft 24. When the sleeve shaft 24 moves in a circular trajectory on the gear plate 9, it will push the two sliders 27 at the rear end of the linkage rod 25 to move back and forth on the slide rail 26, pushing the motion rod 29 to be fixed to the rear ends of the two sliders 27 through the connecting block 28, so that it will be driven by it to move back and forth, thereby The rubber piston block 30 is driven to move back and forth inside the pressure gas cylinder 18, and the connecting pipe 17 is connected to the inside of the arc-shaped suction box 7. The arc-shaped suction box 7 will suck in the smoke generated during forging through the suction groove 20, and a one-way valve is arranged inside the connecting pipe 17, so that only air can be injected into the pressure gas cylinder 18. When extracting, the arc-shaped suction box 7 will suck in the smoke generated during forging through the suction groove 20, and enter the inside of the pressure gas cylinder 18, and be discharged through another pipe body with a built-in one-way valve.
