Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of aluminum ingot processing, and more specifically, to a striking device for demolding aluminum ingots. Background Technology

[0002] In aluminum ingot casting production, the demolding process is a crucial step connecting casting and subsequent processing, directly affecting production continuity and the yield of finished aluminum ingots. Currently, the industry generally relies on manual hammering or chisel-wielding to strike the aluminum ingot with vibration, separating it from the inner wall of the mold, for demolding operations of small and medium-sized molds.

[0003] However, this manual hammering method has many drawbacks: on the one hand, the operation requires workers to repeatedly adjust the hammering angle and force around the mold, which is not only labor-intensive but also requires continuous hammering for a period of time to complete demolding due to the tight fit between the aluminum ingot and the mold, severely restricting production efficiency; on the other hand, it is difficult to precisely control the hammering force. Too little force will not demold smoothly, while too much force will easily cause the mold edge to crack or the aluminum ingot surface to dent, increasing mold maintenance costs and the risk of product scrap. In addition, the metal shavings and vibration noise generated during the hammering process can also pose safety hazards and occupational health threats to operators. Therefore, there is an urgent need for a highly automated aluminum ingot demolding hammering device with controllable force to solve the problems of inconvenience, low efficiency and safety hazards caused by the existing manual hammering method. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this disclosure provide a hammering device for demolding aluminum ingots, which solves the technical problem that in the prior art, the operation process requires workers to repeatedly adjust the hammering angle and force around the mold, which is not only labor-intensive, but also requires continuous hammering for a period of time to complete demolding because the aluminum ingot is closely attached to the mold, which seriously restricts production efficiency.

[0005] According to one aspect, at least one embodiment of this disclosure provides a striking device for demolding aluminum ingots, comprising: A platform and a pair of top frames, both of which are mounted on the platform; A support assembly is disposed between the top frame and the platform; A striking component, the striking component being mounted on the platform; The striking assembly includes a horizontal groove, which is horizontally opened on the side end face of the frame. A movable frame is connected to the horizontal groove via a horizontal linear drive. One end of the movable frame is connected to a fixed frame via a vertical linear drive. A drive motor is horizontally mounted on the fixed frame. A rotating shaft is provided at the output end of the drive motor. Several protrusions are provided around the outer surface of the rotating shaft.

[0006] As a further technical solution, the outer end face of the convex layer is rotatably connected to a striking plate via a pin, and several springs are connected between the surface of the striking plate and the convex layer. A conveyor belt is installed in the frame, and the rotating shaft is located directly above the conveyor belt.

[0007] As a further technical solution, the support assembly includes a pair of brackets, each of which is horizontally fixed to one end of the top frame. The brackets are located on both sides of the conveyor belt and are relatively parallel. The surface of the brackets is provided with long grooves.

[0008] As a further technical solution, several pulleys are horizontally rotatably connected inside the long trough, and a pair of slide rails are provided at both ends of the platform surface. The slide rails are 90° opposite to the conveyor belt, and the top frame is slidably connected to the pair of slide rails.

[0009] As a further technical solution, telescopic cylinders are provided at both ends of the platform surface, the output end of the telescopic cylinders is connected to the top frame, and the cross-section of the bracket is L-shaped.

[0010] As a further technical solution, a number of rolling rods are rotatably connected inside the frame, and the rolling rods are supported on the top of the conveyor belt.

[0011] As a further technical solution, the striking plate is restricted to a unilateral rotation structure by the connection with the convex layer pin.

[0012] As a further technical solution, the upper surface of the conveyor belt is slightly higher than the surface of the platform.

[0013] The beneficial effects of the embodiments disclosed herein are as follows: 1. In this disclosure, the striking assembly solves the problem of low efficiency in manual striking through an automated striking design. A rotating shaft drives the striking plate to impact at high frequency, while spring buffers prevent mold damage and ensure uniform striking force throughout. The moving frame and fixed frame allow for multi-dimensional adjustment to adapt to different mold specifications. This structure reduces manual labor intensity, avoids mold damage or aluminum ingot scrapping due to uncontrolled force, significantly improves demolding efficiency, and meets the needs of large-scale production.

[0014] 2. In this disclosure, the support component solves the problem of mold wobbling during impact through a stable limiting design. An L-shaped bracket secures the mold from the bottom and sides, while pulleys reduce conveying resistance. A telescopic cylinder drives the top frame to move along the slide rail, flexibly adjusting the spacing to adapt to molds of different widths. This structure ensures precise mold positioning during impact, improves impact effectiveness, and avoids surface damage to aluminum ingots caused by mold displacement, ensuring product quality stability and reducing equipment maintenance costs.

[0022] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0023] like Figures 1-4 As shown, a striking device for demolding aluminum ingots according to an embodiment of the present disclosure is illustrated, comprising: A platform 1 and a pair of top frames 2, wherein the top frames 2 are both mounted on the platform 1; Support component 4 is disposed between the top frame 2 and the platform 1; A striking component 3 is disposed on the platform 1; The striking assembly 3 includes a horizontal groove 3-1, which is horizontally opened on the side end face of the platform 1. A movable frame 3-2 is connected to the horizontal groove 3-1 via a horizontal linear drive. One end of the movable frame 3-2 is connected to a fixed frame 3-3 via a vertical linear drive. A drive motor 3-4 is horizontally mounted on the fixed frame 3-3. A rotating shaft 3-5 is provided at the output end of the drive motor 3-4. Several protrusions 3-6 are provided around the outer surface of the rotating shaft 3-5. A striking plate 3-7 is rotatably connected to the outer end face of the protrusions 3-6 via a pin. Several springs 3-8 are connected between the surface of the striking plate 3-7 and the protrusions 3-6. A conveyor belt 3-9 is installed in the platform 1, and the rotating shaft 3-5 is located directly above the conveyor belt 3-9.

[0024] In some examples, a striking assembly 3 is designed to achieve rapid demolding of aluminum ingot molds. This assembly includes a horizontally extending transverse groove 3-1 on the side end face of a frame 1. An internal movable frame 3-2 is driven by a horizontal linear drive device (such as a lead screw mechanism) and can move along the length of the transverse groove 3-1 to adjust the striking position. A vertical linear drive device (such as an electric push rod) at one end of the movable frame 3-2 is fixed vertically downwards, and its output end is connected to a fixed frame 3-3, which can drive the fixed frame 3-3 to rise and fall, adjusting the striking height. A drive motor 3-4 on the fixed frame 3-3 is horizontally mounted, and its output end has a rotating shaft 3-5 keyed to the motor shaft. A raised layer 3-6 is evenly distributed around the surface of the shaft. A striking plate 3-7 on the outer end face is rotatably connected by a pin. A spring 3-8 between the plate and the raised layer 3-6 is welded at one end to the surface of the striking plate 3-7 and at the other end to the side of the raised layer 3-6, always applying an outward elastic force to the striking plate 3-7. The conveyor belt 3-9 in the frame 1 is used to receive the falling aluminum ingots, and the rotating shaft 3-5 is located directly above the conveyor belt 3-9 to ensure that the position is accurately aligned with the mold.

[0025] During operation, the horizontal linear drive device moves the movable frame 3-2 to adjust the lateral position of the striking action, while the vertical linear drive device lowers the fixed frame 3-3, bringing the striking plate 3-7 close to the mold surface. The drive motor 3-4 then rotates the rotating shaft 3-5, causing the raised layer 3-6 to rotate with the shaft. Under the combined action of centrifugal force and the elastic force of the spring 3-8, the striking plate 3-7 opens outwards, periodically impacting the outer wall of the mold. The elasticity of the spring 3-8 allows the striking plate 3-7 to quickly return to its original position after impact, achieving continuous striking and promoting the separation of the aluminum ingot from the mold. The high-speed rotation of the rotating shaft 3-5, combined with multiple striking plates 3-7, achieves high-frequency continuous striking, improving demolding efficiency. The elastic buffer of the spring 3-8 prevents excessive striking force from damaging the mold, while also enhancing the fit between the striking plate 3-7 and the mold. The multi-dimensional adjustment of the movable frame 3-2 and the fixed frame 3-3 adapts to molds of different specifications, expanding the applicability of the device. The synchronous conveying of the conveyor belt 3-9 automates the demolding operation, reducing manual intervention. This component combines rotary drive with elastic striking to achieve efficient demolding of aluminum ingot molds, ensuring continuous production.

[0026] like Figures 1-4As shown in the figure, the support component 4 in this embodiment includes a pair of brackets 4-1, each of which is horizontally fixed to one end of the top frame 2. The brackets 4-1 are located on both sides of the conveyor belt 3-9 and are relatively parallel. The surface of the bracket 4-1 is provided with a long groove 4-2, and several pulleys 4-3 are horizontally rotatably connected in the long groove 4-2. A pair of slide rails 4-4 are provided at both ends of the surface of the platform 1. The slide rails 4-4 are 90° opposite to the conveyor belt 3-9. The top frame 2 is slidably connected to the pair of slide rails 4-4. Telescopic cylinders 4-5 are provided at both ends of the surface of the platform 1. The output end of the telescopic cylinder 4-5 is connected to the top frame 2. The cross-section of the bracket 4-1 is L-shaped.

[0027] In some examples, a support assembly 4 is designed to achieve stable fixation of the aluminum ingot mold. This assembly includes a pair of horizontally fixed brackets 4-1 at one end of the top frame 2, located parallel to each other on both sides of the conveyor belt 3-9, with an L-shaped cross-section. The horizontal part supports the bottom of the mold, while the vertical part restricts the lateral movement of the mold. Several pulleys 4-3 are evenly distributed in the long grooves 4-2 on the surface of the brackets 4-1, which are horizontally rotatably connected to reduce friction between the mold and the brackets 4-1 and facilitate mold transport. A pair of slide rails 4-4 at both ends of the surface of the platform 1 are distributed at 90° to the conveyor belt 3-9. The bottom of the top frame 2 is slidably connected to the slide rails 4-4 via a slider, and can move along the direction of the slide rails 4-4 to adjust the spacing of the brackets 4-1. Telescopic cylinders 4-5 at both ends of the surface of the platform 1 are horizontally fixed, with their output ends connected to the side of the top frame 2, which can drive the top frame 2 to slide along the slide rails 4-4 to open and close the brackets 4-1.

[0028] During operation, based on the width of the aluminum ingot mold, the telescopic cylinder 4-5 pushes the top frame 2 to move along the slide rail 4-4, adjusting the spacing between the two side brackets 4-1 so that the vertical part of the brackets 4-1 fits against the sides of the mold. When the mold moves on the conveyor belt 3-9 above the brackets 4-1, the pulleys 4-3 roll with the mold, reducing resistance. The L-shaped structure of the brackets 4-1 simultaneously limits the mold from the bottom and sides, preventing the mold from shaking or shifting during the hammering process, ensuring that the hammering force is accurately applied to the mold. The sliding cooperation between the slide rail 4-4 and the top frame 2 makes it easy to adjust the spacing of the brackets 4-1 to adapt to molds of different widths. The drive of the telescopic cylinder 4-5 enables automated adjustment, improving operating efficiency. The rolling action of the pulleys 4-3 reduces the mold conveying resistance and avoids scratches on the mold surface. The bidirectional limiting of the L-shaped brackets 4-1 enhances support stability, ensuring that the mold position is fixed during hammering and improving the demolding effect. This component, through the combination of adjustable clamping and stable support, provides reliable fixation for the aluminum ingot mold, ensuring the smooth progress of the hammering demolding operation.

[0029] For example, such as Figure 3 As shown, a plurality of rolling rods 5 are rotatably connected inside the frame 1, and the rolling rods 5 are supported on the top of the conveyor belt 3-9.

[0030] In some examples, several rolling rods 5, rotatably connected within the frame 1, are horizontally distributed and supported on the top of the conveyor belt 3-9. The rolling rods 5 provide upward support to the conveyor belt 3-9, preventing it from sagging due to the load of the aluminum ingot mold and ensuring smooth operation. Simultaneously, the rolling rods 5 rotate synchronously with the conveyor belt 3-9, reducing friction between them, extending the service life of the conveyor belt 3-9, and ensuring smooth and stable mold conveying.

[0031] For example, such as Figure 4 As shown, the striking plate 3-7 is restricted to a unilateral rotation structure by means of the pin connection with the protrusion 3-6.

[0032] In some examples, the striking plate 3-7 is restricted to a unilateral rotation structure by a pin connection with the raised layer 3-6, meaning it can only rotate in the direction closer to the mold. This structure ensures that the striking plate 3-7 effectively impacts the mold when rotating, while the reverse rotation is restricted, preventing the impact force from being dispersed due to excessive flipping. This ensures that each impact provides sufficient impact force, improves the demolding effect, and prevents the spring 3-8 from being damaged by excessive stretching.

[0033] For example, such as Figure 1 As shown, the upper surface of the conveyor belt 3-9 is slightly higher than the surface of the frame 1.

[0034] In some examples, the upper surface of the conveyor belt 3-9 is slightly higher than the surface of the stand 1, which reduces the contact friction between the mold and the stand 1 during mold transport. This design ensures that the mold only contacts the conveyor belt 3-9, facilitating smooth movement of the mold by the conveyor belt 3-9 and preventing scratch damage to the bottom of the mold caused by the surface of the stand 1. At the same time, it allows the bracket 4-1 of the support component 4 to clamp the mold from both sides, ensuring accurate positioning of the mold during the striking process.

[0035] In practical use: The aluminum ingot mold is placed on the conveyor belt 3-9. The telescopic cylinder 4-5 pushes the top frame 2 to move along the slide rail 4-4. The L-shaped brackets 4-1 on both sides are close to the mold, and the pulleys 4-3 reduce movement friction and limit movement from the bottom and sides. The moving frame 3-2 adjusts its lateral position along the transverse groove 3-1, and the vertical linear drive drives the fixed frame 3-3 to descend, so that the striking plate 3-7 is close to the mold. The drive motor 3-4 drives the rotating shaft 3-5 to rotate, and the striking plate 3-7 on the protrusion 3-6 periodically impacts the mold under the action of the spring 3-8. The single-sided rotation design ensures that the impact force is concentrated. After the aluminum ingot is removed, it is conveyed with the conveyor belt 3-9. The rolling rod 5 supports the conveyor belt 3-9 to prevent sagging. The entire process realizes automated knocking demolding without the need for manual adjustment of angle and force.
