Description

Technical Field

[0001] The utility model belongs to the field of ingot production, and particularly relates to an impurity removal device for ingot forming. Background Technique

[0002] Metal casting is a common manufacturing process. By injecting molten metal or alloy into a pre-prepared mold and allowing it to cool and solidify, metal parts or products with the required shape and size can be obtained. Taking an aluminum alloy ingot as an example, to improve the quality and purity of the ingot, usually a layer of the surface of the molten aluminum alloy liquid needs to be scraped off to remove the scum or impurities on the surface of the molten aluminum alloy liquid.

[0003] In the prior art, Patent CN202220005256.1 discloses a slag scraping mechanism for aluminum ingot casting. By setting an inclined scraper, moving the scraper can scoop up the scum on the scraper, and then the scum on the scraper is scraped off by a cleaning sleeve for treatment. In the above solution, when the scraper is located in the molten aluminum, the inclined setting of the scraper can facilitate scooping up the scum on the scraper. However, when the scraper moves upward and leaves the molten aluminum, the molten aluminum remaining on the scraper may drive the scum to slide down the scraper and return to the mold under the action of gravity, resulting in an unsatisfactory slag removal effect. Content of the Utility Model

[0004] Aiming at the deficiencies in the prior art, the utility model provides an impurity removal device for ingot forming to solve the problem that when the scraper moves upward and leaves the molten aluminum, the molten aluminum remaining on the scraper may drive the scum to slide down the scraper and return to the mold under the action of gravity.

[0005] According to the embodiments of the utility model, the following technical solutions are adopted:

[0006] The impurity removal device for ingot forming includes an impurity removal component and a driving component. The impurity removal component includes a slag removal shovel. The slag removal shovel includes a fixed plate and a movable plate hinged to the fixed plate. The free end of the movable plate is provided with a wedge surface, and the thickness of the movable plate at the wedge surface decreases from the direction close to the fixed plate to the direction far from the fixed plate. An adjusting member for adjusting the deflection angle of the movable plate relative to the fixed plate is installed on the fixed plate; the driving component is used to drive the fixed plate to move horizontally or vertically.

[0007] Compared with the prior art, the utility model has the following beneficial effects:

[0008] In this solution, an adjusting member is provided to adjust the angle of the movable plate. When the movable plate is located in the molten aluminum, an obtuse angle is formed between the working surface of the movable plate and the fixed plate, that is, the free end of the movable plate inclines downward. The driving assembly drives the fixed plate to move, driving the movable plate to move in the molten aluminum to salvage the floating slag. When the movable plate moves to the end of the ingot mold, while lifting the fixed plate upward, the angle between the movable plate and the fixed plate is gradually reduced by the adjusting member, thereby reducing the possibility of the floating slag falling off the movable plate to a certain extent.

[0009] Furthermore, the adjusting member includes a connecting rod. One end of the connecting rod is hinged to the free end of the movable plate, and the other end of the connecting rod is hinged with a slider. The slider is slidably connected to the fixed plate in the vertical direction.

[0010] Furthermore, the driving assembly includes a bracket, a longitudinal slide rail arranged on the bracket, a first slide plate slidably connected to the longitudinal slide rail, a transverse slide rail arranged on the first slide plate, a second slide plate slidably connected to the transverse slide rail, and the fixed plate is detachably connected to the second slide plate.

[0011] Furthermore, the driving assembly further includes a base, and the bracket is rotatably connected to the base.

[0012] Furthermore, a scraping member for scraping the floating slag adhered to the movable plate is installed on the fixed plate. The scraping member includes a cleaning rod slidably connected to the fixed plate and a cleaning member detachably connected to the cleaning rod.

[0013] Furthermore, the cleaning member includes a fixing part, a sliding part slidably connected to the fixing part, and bristles or a scraper arranged on the sliding part. A spring is connected between the sliding part and the fixing part.

[0014] Furthermore, a roller is rotatably connected to the free end of the movable plate, and the axis of the roller is parallel to the hinge axis of the movable plate relative to the fixed plate.

[0015] Furthermore, baffles are arranged on both sides of the movable plate. Description of the Drawings

Detailed implementation mode

[0020] The present utility model will be further described in detail below in conjunction with the accompanying drawings of the specification, and specific implementation modes will be given.

[0021] As Figure 1 , Figure 2 , Figure 3 shown, the impurity removal device for ingot forming includes an impurity removal component and a driving component. The impurity removal component includes a slag removal shovel. The slag removal shovel includes a fixed plate 5 and a movable plate 6 hinged to the fixed plate 5. A wedge surface 8 is provided at the free end of the movable plate 6. The thickness of the movable plate 6 at the wedge surface 8 decreases from the direction close to the fixed plate 5 to the direction far from the fixed plate 5. Specifically, the wedge surface 8 is provided on the working surface of the movable plate 6. When the movable plate 6 moves in the molten aluminum, the wedge surface 8 has a certain pushing effect on the molten aluminum, which is convenient for fishing the floating slag onto the movable plate 6.

[0022] A regulating member for adjusting the deflection angle of the movable plate 6 relative to the fixed plate 5 is installed on the fixed plate 5. Specifically, the regulating member includes a connecting rod 7. One end of the connecting rod 7 is hinged to the free end of the movable plate 6, and the other end of the connecting rod 7 is hinged to a slider 9. The slider 9 is slidably connected to the fixed plate 5 in the vertical direction. A cylinder for driving the slider 9 to slide is installed on the fixed plate 5. By driving the slider 9 to slide in the vertical direction, the connecting rod 7 can drive the movable plate 6 to deflect. For example, taking the state where the movable plate 6 and the fixed plate 5 are in a horizontal state as the initial state, when the slider 9 slides downward at this time, the free end of the movable plate 6 can deflect downward, and when the slider 9 slides upward at this time, the free end of the movable plate 6 can deflect upward.

[0023] The driving component is used to drive the fixed plate 5 to move horizontally or vertically. Specifically, the driving component includes a bracket 2, a longitudinal slide rail arranged on the bracket 2, a first slide plate 3 slidably connected to the longitudinal slide rail, a transverse slide rail arranged on the first slide plate 3, and a second slide plate 4 slidably connected to the transverse slide rail. A cylinder for driving the first slide plate 3 to slide is installed on the bracket 2, and a cylinder for driving the second slide plate 4 to slide is installed on the first slide plate 3. The track directions of the transverse slide rail and the longitudinal slide rail are perpendicular to each other. By sliding the first slide plate 3 on the longitudinal slide rail, the second slide plate 4 can be driven to generate a longitudinal displacement, and by sliding the second slide plate 4 on the transverse slide rail, the transverse displacement of the second slide plate 4 can be realized, that is, the second slide plate 4 can generate a longitudinal displacement or a transverse displacement. The fixed plate 5 is detachably connected to the second slide plate 4. Specifically, the fixed plate 5 is bolted to the second slide plate 4, and the fixed plate 5 can be driven to move horizontally or vertically through the second slide plate 4.

[0024] During specific use, the bracket 2 is placed beside the ingot mold, and the direction of the transverse slide rail is along the length direction of the ingot mold. Taking Figure 1 the direction shown as an example, if the sliding direction of the second slide plate 4 is the left - right direction, then the length direction of the ingot mold is also along the left - right direction, so that the slag removal shovel can salvage along the ingot mold during the left - right movement. Then, by sliding the first slide plate 3 on the longitudinal slide rail, the height of the movable plate 6 is adjusted so that the movable plate 6 is located in the molten aluminum. When the movable plate 6 is located in the molten aluminum, the working surface of the movable plate 6 and the fixed plate 5 are adjusted to form an obtuse angle, that is, the free end of the movable plate 6 inclines downward.

[0025] By sliding the second slide plate 4 in the transverse slide rail, the movable plate 6 is driven to move along the length direction of the ingot mold to salvage the floating slag in the molten aluminum. When the movable plate 6 moves to the end of the ingot mold, the first slide plate 3 is driven to slide upward, so that the fixed plate 5 can be lifted upward. At the same time, the slider 9 is slid upward, and the free end of the movable plate 6 is pulled upward by the connecting rod 7 to gradually reduce the angle between the movable plate 6 and the fixed plate 5, thereby reducing the possibility of the floating slag falling from the movable plate 6 to a certain extent.

[0026] In another embodiment of the present utility model, in order to facilitate adjusting the direction of the transverse slide rail along the length direction of the ingot mold, the driving component further includes a base 1. The bracket 2 is rotatably connected to the base 1, and a motor for driving the bracket 2 to rotate is installed on the base 1. By rotating the bracket 2, when placing the base 1, as long as the base 1 is placed beside the ingot mold, the angle of the transverse slide rail can be adjusted by rotating the bracket 2, without the need to move the base 1 multiple times for adjustment.

[0027] In another embodiment of the present utility model, in order to facilitate the cleaning of the scum adhering to the movable plate 6, a scraping member for scraping the scum adhering to the movable plate 6 is installed on the fixed plate 5. Specifically, the scraping member includes a cleaning rod 10 slidably connected to the fixed plate 5 and a cleaning member detachably connected to the cleaning rod 10. Taking the cleaning rod 10 slidably connected to the fixed plate 5 in the transverse direction as an example, the sliding direction of the cleaning rod 10 is perpendicular to the hinge axis of the movable plate 6. A cylinder for driving the sliding of the cleaning rod 10 is installed on the fixed plate 5. When the movable plate 6 is in a horizontal state, by driving the sliding of the cleaning rod 10, the cleaning rod 10 drives the cleaning member to slide on the movable plate 6, and the scum adhering to the movable plate 6 can be scraped off. In order to facilitate the lower end of the cleaning member to contact and press against the movable plate 6 for scraping the scum, a cleaning block 11 is slidably connected to the end of the cleaning rod 10 in the vertical direction, the cleaning member is installed on the cleaning block 11, and a cylinder for driving the vertical movement of the cleaning block 11 is installed on the cleaning rod 10.

[0028] The cleaning member includes a fixed part 12, a sliding part 13 slidably connected to the fixed part 12, and bristles 14 or a scraper provided on the sliding part 13. A spring 15 is connected between the sliding part 13 and the fixed part 12. The fixed part 12 is bolted to the cleaning block 11. By sliding the sliding part 13 relative to the fixed part 12, the bristles 14 or the scraper can be pressed against the surface of the movable plate 6, which has a better scraping effect and also enables the cleaning member to clean the scum at the wedge surface 8.

[0029] In another embodiment of the present utility model, when the movable plate 6 moves to the end close to the ingot mold, in order to facilitate the movable plate 6 to abut against the inner wall of the ingot mold during deflection and move along the inner wall of the ingot mold, so as to better salvage the scum, a roller 17 is rotatably connected to the free end of the movable plate 6. The axis of the roller 17 is parallel to the hinge axis of the movable plate 6 relative to the fixed plate 5. Then when the free end of the movable plate 6 deflects upward, when the roller 17 contacts the inner wall of the ingot mold, by continuing to deflect the movable plate 6 upward, the roller 17 can rotate along the inner wall of the ingot mold and then leave the inner wall of the ingot mold.

[0030] In another embodiment of the present utility model, in order to prevent the scum from falling over from both sides of the movable plate 6 when the movable plate 6 is lifted upward, baffles 16 are provided on both sides of the movable plate 6. In order to prevent interference between the baffles 16 and the fixed plate 5 during the deflection of the movable plate 6, there is a certain distance between the end of the baffle 16 and the fixed plate 5.
