Description

Technical Field

[0001] Embodiments of the present invention relate to the technical field of pressing devices, and specifically, to a pressing device for producing aluminum alloy additives. Background Art

[0002] As an important material widely used in many fields, during the production process of aluminum alloy, adding aluminum alloy additives can effectively improve various indexes of the product; for the processing of aluminum alloy additives, it is mainly completed by pressing. Specifically, after putting metal powder into a pressing mold, it is pressed into a metal block, and such metal blocks are also easier to transport than metal powder.

[0003] In the currently used pressing device, during feeding, a movable hopper is used to put metal powder into the lower die. The pressing head presses down to complete the pressing and forming. During discharging, first, the metal block in the lower die is ejected to the top surface of the lower die, and then when the hopper moves to eject the metal block for discharging and at the same time put metal powder into the lower die, the above process has the following drawbacks: At the moment when the pressing head presses down into the lower die for forming, the air inside the forming cavity is squeezed out, which causes some metal powder to be discharged together with the air and cannot be formed synchronously. When the hopper moves again to push the metal block for discharging and put metal powder into the lower die, the just-missing metal powder will be discharged together with the metal block, resulting in waste; currently, although a powder receiving port is opened on the path where the metal block is discharged, the recoverable metal powder is ultimately limited, and there will still be some metal powder remaining on the top surface of the lower die and cannot be recycled. Summary of the Invention

[0004] To overcome the above defects, embodiments of the present invention provide a pressing device for producing aluminum alloy additives, which solves the technical problem that metal powder always remains on the top surface of the lower die of the pressing device in the related art and cannot be fully and timely recycled.

[0005] According to one aspect, at least one embodiment of the present invention provides a pressing device for producing aluminum alloy additives, including: A frame body, on which a lower die is provided. The lower die is provided with a pressing through hole that penetrates up and down. A top column is arranged to move up and down in the pressing through hole. The top column is configured to be coplanar with the top surface of the lower die after rising to eject the metal block in the pressing through hole; A scraping arc plate, which reciprocally slides relative to the lower die, and the bottom surface of the scraping arc plate abuts against the top surface of the lower die. The scraping arc plate has a side opening, and a pushing plate for pushing the metal block is arranged in the side opening. The scraping arc plate has a discharging state and a reset state; When the scraping arc plate is in the discharging state, the side opening faces the discharging direction, and the pushing plate can push out the metal block under the drive of the scraping arc plate; When the scraping arc plate is in the reset state, the side opening faces away from the discharging direction, and the scraping arc plate can scrape the metal powder on the top surface of the lower die into the pressing through hole.

[0006] For example, in a pressing device for producing aluminum alloy additives provided by at least one embodiment of the present invention, a support adjustment block is reciprocally slidably provided on the frame along the discharging direction, and the support adjustment block is slidably connected to the top of the scraping arc plate along the arc direction for adjusting the scraping arc plate to the discharging state or the reset state, and the top surface of the pushing plate is lower than the bottom surface of the support adjustment block.

[0007] For example, in a pressing device for producing aluminum alloy additives provided by at least one embodiment of the present invention, a gear is rotatably connected to the support adjustment block, and a rack is provided on the outer peripheral wall of the scraping arc plate, and the gear meshes with the rack for driving the scraping arc plate to slide so as to change the orientation of the side opening to adjust the scraping arc plate to the discharging state or the reset state.

[0008] For example, in a pressing device for producing aluminum alloy additives provided by at least one embodiment of the present invention, the scraping arc plate is semicircular or U-shaped, and the projections of the scraping arc plate and the pushing plate along the horizontal plane can both pass through the pressing through hole.

[0009] For example, in a pressing device for producing aluminum alloy additives provided by at least one embodiment of the present invention, there are two support adjustment blocks, and the two support adjustment blocks are respectively located on both sides of the pressing through hole and are symmetrically arranged. After the two scraping arc plates slide, they can abut against each other to be combined into the discharging state or the reset state; Wherein, after the two pushing plates slide following the scraping arc plate, they can abut against each other so as to pass through the pressing through hole in the discharging state.

[0010] For example, in a pressing device for producing aluminum alloy additives provided by at least one embodiment of the present invention, it further includes: A hopper, the hopper is reciprocally slidably arranged on the frame along the discharging direction, the hopper is located above the lower die, the hopper can slide to directly above the pressing through hole to feed materials into the pressing through hole, and the hopper is connected to the support adjustment block and is located on the side of the support adjustment block away from the discharging direction so that the hopper can push the support adjustment block to reciprocally slide.

[0011] For example, in a pressing device for producing aluminum alloy additives provided by at least one embodiment of the present invention, a connecting rod detachably connected to the hopper is provided on the support adjustment block.

[0012] For example, in a pressing device for producing an aluminum alloy additive provided by at least one embodiment of the present invention, there are a plurality of pressing through-holes, and the plurality of pressing through-holes are arranged in a matrix. A plurality of upper die pressing heads are arranged on the frame in a lifting manner, and the upper die pressing heads correspond to the pressing through-holes one by one. The upper die pressing heads are used to cooperate with the lower die to form metal blocks in the pressing through-holes.

[0013] For example, in a pressing device for producing an aluminum alloy additive provided by at least one embodiment of the present invention, it further includes: A blanking roller table, which is fixedly arranged on the frame on the side of the lower die close to the discharging direction. The blanking roller table is used to receive and discharge metal blocks.

[0014] The beneficial effects of the embodiments of the present invention are as follows: In the existing device, when the pressing head presses down, some metal powder will be discharged with the air, and these missed powders will be discharged together with the metal blocks, resulting in waste. In this device, in the reset state, the scraping arc plate can scrape the metal powder on the top surface of the lower die into the pressing through-holes, which enables the metal powder that would otherwise be wasted to re-enter the pressing process and reduces the waste of metal powder. In the discharging state, the side opening of the scraping arc plate faces the discharging direction, and the pushing plate can push out the metal block under the drive of the scraping arc plate. Such a design makes the blanking process smoother, and compared with the simple ejection blanking in the existing device, it increases the pushing effect of the pushing plate and can more effectively push out the metal block, ensuring the stability and reliability of blanking.

[0015] By switching the scraping arc plate between the discharging state and the reset state, instead of the traditional form of directly discharging the metal block and the metal powder together, the ejection of the metal block and the recycling of the metal powder are realized, making the working process of the pressing device more continuous, reducing the waste and residue of the metal powder, and ensuring the production stability.

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention.

[0020] For the sake of simplicity of the drawing surface, only the parts related to the disclosure are schematically shown in each figure, and they do not represent their actual structures as products. In addition, for the sake of simplicity and easy understanding of the drawing surface, in some figures, components with the same structure or function are only schematically shown for one of them, or only one of them is marked. In this article, "one" not only means "only this one", but also can mean "more than one" situation, and "several" includes "two" and "more than two".

[0021] In this article, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0022] In the present invention, unless otherwise clearly specified and defined, the first feature being "on" or "under" the second feature may include direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through additional features therebetween. Moreover, the first feature being "above", "over" and "on top of" the second feature includes the first feature being directly above and obliquely above the second feature, or merely indicating that the horizontal height of the first feature is higher than that of the second feature. The first feature being "under", "beneath" and "underneath" the second feature includes the first feature being directly under and obliquely under the second feature, or merely indicating that the horizontal height of the first feature is less than that of the second feature.

[0023] In the description of this embodiment, the orientation or positional relationships such as "upper", "lower", "left" and "right" are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0024] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be construed as indicating or implying relative importance.

[0025] As Figures 1 to 5 shown, it shows a pressing device for producing aluminum alloy additives in an embodiment of the present invention. The frame 1 serves as the support foundation of the entire device, and adjustable feet can be provided at the bottom; the lower die 2 is fixedly installed at a designated position on the frame 1 through bolts. To ensure accuracy, positioning pins can be provided on the frame 1 to cooperate with the positioning holes of the lower die 2. The lower die 2 is provided with a pressing through-hole 201 that penetrates up and down, and a punch 3 is installed in it with a clearance fit. This can not only ensure the smooth lifting and lowering of the punch 3 in the pressing through-hole 201, but also prevent metal powder from entering the gap between the punch 3 and the inner wall of the pressing through-hole 201. The bottom of the punch 3 can be installed on the frame 1 through a hydraulic cylinder, driving the punch 3 to move up and down in the pressing through-hole 201. After rising, it is coplanar with the top surface of the lower die 2 to eject the metal block in the pressing through-hole 201, facilitating the discharge of the metal block. Further, the punch 3 can adopt a cylindrical structure adapted to the pressing through-hole 201, and the top is set as a flat plane to ensure full contact with the metal block and evenly eject the metal block.

[0026] Furthermore, the scraping arc plate 4 can be installed on the frame 1 through a slider and a linear guide rail, reciprocatingly slide relative to the lower die 2, and can be equipped with an active power source (motor) to actively control its movement. The scraping arc plate 4 is integrally arc-shaped, and it should ensure that the scraping arc plate 4 can fully cover the top surface of the lower die 2 during the sliding process. The function of the arc is mainly to ensure that in the reset state, the residual metal powder is concentrated between the arcs at the side opening 401 during the sliding reset and introduced into the pressing through-hole 201; while the push plate welded at the side opening 401 of the scraping arc plate 4 is mainly to scrape the metal powder scraped by the sliding discharge wall of the scraping arc plate 4 out of the lower die 2 earlier in the discharging state, avoiding the synchronous discharge of the two and failing to achieve the purpose of recycling. Moreover, it does not abut against the top surface of the lower die 2 and can act on the ejected metal block, avoiding affecting the movement direction of the metal powder.

[0027] During the discharging and feeding processes of the traditional device, the residual powder cannot be effectively processed. However, through the ingenious design of the scraping arc plate 4 and the pushing plate 402, this device combines the two steps of discharging and recycling the residual powder, separately processes the metal block and the residual metal powder, and can scrape the metal powder on the top surface of the lower die 2 into the pressing through-hole 201 in the reset state, achieving effective recycling and being used for pressing again, reducing waste.

[0028] As Figures 1 to 7 shown, the scraping arc plate 4 needs to switch between the discharging state and the reset state, using a movement trajectory similar to a horizontal arc, which can provide a more stable, smooth and space-saving guiding path for the scraping arc plate 4, avoiding the easy jamming or interference with other components when using methods such as swinging, making the whole structure more compact and facilitating the reciprocating change of its side opening 401 in the same or opposite direction as the discharging direction.

[0029] In addition, the reason for the sliding connection with the top of the scraping arc plate 4 is to avoid interfering with the working components (the pushing plate 402 and the scraping part at the bottom of the scraping arc plate 4). The bottom surface of the scraping arc plate 4 needs to be in close contact with the top surface of the lower die 2 for scraping work, and the pushing plate 402 at the side opening 401 is also used for pushing. If it is connected to the bottom or side surface, it will interfere with the position change of the pushing plate 402 back and forth. While the sliding connection with the top will not interfere with the bottom surface and side working components (the pushing plate 402) of the scraping arc plate 4, ensuring the normal functioning of each component.

[0030] Specifically, the support adjustment block 5 can adopt a block structure, which is used to provide the support and installation basis for the scraping arc plate 4. The top of the scraping arc plate 4 can be slidably connected to the chute at the bottom of the support adjustment block 5 through a T-shaped structure, and the chute is preferably arranged along a horizontal arc to ensure that the scraping arc plate 4 can freely switch between the discharging state and the reset state after sliding.

[0031] As Figures 1 to 8As shown, the meshing transmission between the gear 6 and the rack 403 belongs to direct-contact rigid transmission, which can achieve precise motion transmission. In the aluminum alloy additive pressing device, the scraping arc plate 4 needs to accurately switch between the discharging state and the reset state. The transmission between the gear 6 and the rack 403 can ensure the motion trajectory and position accuracy of the scraping arc plate 4, thereby improving the working reliability of the pressing device. Moreover, the transmission structure of the gear 6 and the rack 403 is relatively simple and occupies less space, enabling reasonable layout within the limited device space. The gear 6 on the support adjustment block 5 is directly meshed with the rack 403 of the scraping arc plate 4 without complex intermediate transmission components, making the entire driving structure more compact.

[0032] Specifically, during the state switching, the motor on the support adjustment block 5 drives the gear 6 to rotate. The gear 6 meshes with the rack 403, converting the rotational motion into the sliding of the scraping arc plate 4 along the arc trajectory, thereby changing the orientation of the side opening 401. When the side opening 401 faces the discharging direction, it is the discharging state, or when it faces away from the discharging direction, it is the reset state, so as to change the state of the scraping arc plate 4.

[0033] As Figures 1 to 8 shown, the scraping arc plate 4 is designed as a semi-circular or U-shaped. This shape is more convenient for one-piece molding production in the early stage and covers the pressing through-hole 201, enabling the pushing plate 402 to apply uniform thrust to the materials within the entire pressing through-hole 201 when pushing the materials, and can adapt to the adjustment structure of the gear 6 and the rack 403 to change the orientation of the side opening 401 along the arc path.

[0034] As Figures 1 to 8 shown, there are two support adjustment blocks 55. The two support adjustment blocks 55 are respectively located on both sides of the pressing through-hole 201 and are symmetrically arranged. After the two scraping arc plates 44 slide, they can abut against each other to form the discharging state or the reset state. The pushing plate 402402 is arranged horizontally. After the two pushing plates 402402 follow the sliding of the scraping arc plate 44, they can abut against each other so that the projection on the horizontal plane in the discharging state can cover the pressing through-hole 201.

[0035] With the design of two support adjustment blocks 5 and two scraping arc plates 4, compared with the overall U-shaped design, it is more flexible when adjusting the position and angle of the scraping arc plate 4. There is no need to directly slide the side opening 401 on the overall U-shaped scraping arc plate 4 over a large range to change the state. Instead, the scraping arc plates 4 on the two symmetric support adjustment blocks 5 slide along the arc path within a small range. When the ends of the two abut against each other, they can form an integral scraper. The integral scraper can form the side opening 401. When the side opening 401 faces the discharging direction, it is the discharging state, and when the side opening 401 faces away from the discharging direction, it is the reset state; the overall structure is more compact and the movement range is also small.

[0036] The movement of the two scraping arc plates 4 can be precisely controlled by adjusting the positions of the two support adjustment blocks 5 separately. Moreover, if one of the scraping arc plates 4 or the support adjustment blocks 5 malfunctions, only a single component needs to be repaired or replaced, instead of operating on the entire large component as in the case of an integral U-shaped design.

[0037] Specifically, when initially in the discharging state, the ends of the two scraping arc plates 4 are in contact with each other. Similarly, for the pushing plate 402, both of them cover the pressing through-hole 201 along the horizontal projection to achieve the above purpose. When a state change is required, the gear 6 rotates to drive the scraping arc plate 4 to slide, so that the other two ends of the two scraping arc plates 4 are in contact again, changing to the reset state. At this time, the pushing plates 402 may or may not be in contact with each other because it is no longer necessary to push the metal block. Then, the next pressing cycle can be carried out.

[0038] As Figures 1 to 9 shown, the hopper 7 is reciprocally slidably arranged on the frame 1 along the discharging direction. The hopper 7 is located above the lower die 2 and can accurately slide to directly above the pressing through-hole 201 for feeding. At the same time, the hopper 7 is connected to the support adjustment block 5 and arranged in sequence along the discharging direction, which is convenient for the hopper 7 to drive the scraping arc plate 4, eliminating the need for an additional power source. The connecting rod 8 provided on the hopper 7 is detachably connected to the support adjustment block 5. The connecting rod 8 can be a threaded connection structure, with one end screwed into the hopper 7 and the other end cooperating with the corresponding threaded hole on the support adjustment block 5. When the hopper 7 slides, it can push the support adjustment block 5 to reciprocally slide synchronously, realizing their coordinated operation.

[0039] There are several pressing through-holes 201 arranged in a matrix. This arrangement can make full use of the space of the lower die 2 and improve production efficiency. At the same time, several upper die pressing heads 9 are arranged on the frame 1 in a lifting manner, and the upper die pressing heads 9 and the pressing through-holes 201 are in one-to-one correspondence. The lifting of the upper die pressing heads 9 can be realized by a hydraulic cylinder or an electric push rod. During the pressing process, the upper die pressing heads 9 press down to extrude and form the metal blocks in the pressing through-holes 201. In addition, the blanking roller path 10 is fixedly arranged on the frame 1, on one side of the lower die 2 along the discharging direction. The blanking roller path 10 is composed of multiple rollers arranged in parallel. The rollers are installed on the brackets through bearings, and the brackets are fixedly connected to the frame 1. After the metal blocks are discharged, they can fall onto the rollers of the blanking roller path 10 and be conveyed to the subsequent processing area or storage area.

[0040] Working principle: First, the top column 3 is located inside the pressing through-hole 201, the scraping arc plate 4 is in the discharging state, the side opening 401 faces the discharging direction, the hopper 7 slides to directly above the pressing through-hole 201 to put metal powder into the pressing through-hole 201, completing the feeding. At the same time, the scraping arc plate 4 will scrape the remaining part of the metal powder on the lower die 2 and then discharge it into the pressing through-hole 201 (the metal powder that was not completely discharged in the last reset state). Subsequently, it changes to the reset state, the side opening 401 faces away from the discharging direction, the hopper 7 moves away from the lower die 2, and the scraping arc plate 4 scrapes into the pressing through-hole 201 again; it changes to the discharging state, the press head presses down, presses the metal powder in the pressing through-hole 201 into a metal block. After forming, the top column 3 rises to eject the metal block, and the metal block in the pressing through-hole 201 is ejected to the top surface of the lower die 2 to start discharging. The hopper 7 drives the scraping arc plate 4 to slide again, and the pushing plate 402 pushes away the ejected metal block. At the same time, the scraping arc plate 4 scrapes the metal powder to one end of the lower die 2; after discharging, it changes to the reset state again to recover the remaining powder, the side opening 401 faces away from the discharging direction, the hopper 7 resets, the top column 3 descends, and the scraping arc plate 4 scrapes the metal powder at one end of the lower die 2 back into the pressing through-hole 201 for the next round of pressing. Thus, the cycle is completed.

Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
