Description

Technical Field

[0001] This utility model mainly relates to the technical field of aluminum alloy casting equipment, specifically an aluminum-zinc-silicon alloy ingot linear casting machine. Background Technology

[0002] With the rapid development of high-end industries such as new energy, aerospace, and automobile manufacturing, the demand for aluminum-zinc-silicon alloy materials is increasing, and higher requirements are being placed on the specifications, purity, internal structure, and production efficiency of alloy ingots. As the basic raw material for subsequent processing (such as rolling and forging), the casting quality of aluminum-zinc-silicon alloy ingots directly determines the performance of downstream products. Therefore, efficient, precise, and stable casting equipment has become a key core equipment in the field of alloy material production. In the traditional aluminum-zinc-silicon alloy ingot casting process, conventional fixed-mold casting equipment typically fixes the mold to the ground foundation and injects molten alloy into the mold by moving the casting pot. After a single set of molds is cast, the next round of casting can only be carried out after the molten alloy has completely solidified and the mold has been manually removed. This method cannot achieve continuous operation, has low production efficiency, and is difficult to adapt to the needs of large-scale mass production. Utility Model Content

[0013] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0014] Example: Linear casting machine for aluminum-zinc-silicon alloy ingots like Figure 1-5 As shown, the linear casting machine for aluminum-zinc-silicon alloy ingots includes the following components: track 10, mold carrier 20, mold 30, drive mechanism 40, and electrical control system 50. The track 10 includes a square steel bracket 101, a mounting base plate 102, and a track square steel 103. Several evenly distributed mounting base plates 102 are fixedly installed on the front and rear sides of the square steel bracket 101, and track square steel 103 is fixedly installed on the front and rear sides of the top surface of the square steel bracket 101. The mold carrier 20 includes a body 201 and wheels 202. Wheel frames 203 are fixedly installed at the four corners of the bottom surface of the body 201. Wheels 202 are rotatably installed at the bottom of each wheel frame 203. The wheels 202 cooperate with corresponding track square steel 103. The body 201 of the mold carrier 20 is driven by a drive mechanism to move along the track square steel 103. First saddles are fixedly installed on both sides of the body 201.

[0015] The working principle described above is as follows: In this device, the track 10 is the basic support structure of the entire casting machine, the square steel bracket 101 provides stable frame support for the whole, and the several evenly distributed mounting base plates 102 fixed on the front and rear sides can enhance the connection stability between the square steel bracket 101 and the ground and prevent the track from shifting during use; the track square steel 103 fixed on the front and rear sides of the top of the square steel bracket 101 provides a precise guide track for the movement of the mold carrying vehicle 20; the traveling wheels 202 rotatably mounted on the traveling wheel frames 203 at the four corners of the bottom surface of the mold carrying vehicle 201 cooperate with the corresponding track square steel 103. Under the drive of the drive mechanism, the traveling wheels 202 roll along the track square steel 103, thereby realizing the smooth movement of the mold carrying vehicle 20; the first saddle fixedly installed on both sides of the vehicle body 201 is a key structure for subsequent connection with the drive mechanism, providing an interface for reliable connection between the two.

[0016] The drive mechanism 40 includes a rail frame 401. The bottom of the rail frame 401 is provided with a roller assembly 60 that cooperates with a square steel support 101. A reduction motor 402, a servo motor, is fixedly mounted at the center of the top surface of the rail frame 401 via a motor mounting seat. The output shaft of the reduction motor 402 vertically penetrates the rail frame 401 and is connected to its bearing. A support square steel 104, parallel to the rail square steel 103, is fixedly mounted at the center of the top surface of the square steel support 101. A rack 403 is fixedly mounted on the top surface of the support square steel 104. A drive gear 404 meshing with the rack 403 is fixedly mounted at the output end of the reduction motor 402. The electrical control system 50 is used for the operation control of the drive mechanism 40. A second saddle is fixedly mounted on one side of the rail frame 401. The rail frame 401 and the car body 201 are connected by a traction pin that engages with the first saddle via the second saddle.

[0017] The drive mechanism 40 drives the mold carrier 20 to move. The roller assembly 60 at the bottom of the track frame 401 cooperates with the square steel bracket 101 to provide support and guidance for the movement of the track frame 401. The reduction motor 402, which is fixed to the center of the top surface of the track frame 401 through the motor mounting seat, has its output shaft running vertically through the track frame 401 and connected by bearings to ensure stable rotation of the output shaft. The support square steel 104, which is parallel to the track square steel 103 and fixed to the center of the top surface of the square steel bracket 101, provides a stable mounting base for the rack 403. The rack 403 is fixed to one side of the support square steel 104. The drive gear 404 fixed at the output end of the geared motor 402 meshes with the rack 403. When the geared motor 402 starts, the drive gear 404 rolls on the rack 403, thereby driving the rail frame 401 to move along the direction of the supporting square steel 104. The second saddle fixed on one side of the rail frame 401 cooperates with the first saddle on the body 201 of the mold carrier 20 and is connected by a traction pin, thereby driving the mold carrier 20 to move along the rail square steel 103. The electrical control system 50 operates and controls the operation of the drive mechanism 40 to achieve precise control of the movement of the mold carrier 20. The electrical control system 50 includes a field operation box 501, which contains a programmable controller and a high-precision encoder. Several evenly distributed detection limit switches are fixedly installed on the front and rear sides of the track 10. The detection limit switches are used to detect the position of the vehicle body 201. The electrical control system 50 has manual, automatic and interlocking functions, and adopts ABB programmable servo drive and high-precision encoder to form a closed-loop control.

[0018] The electrical control system 50 is the core of the entire casting machine's control. The on-site control box 501 provides a convenient interface for operators, enabling on-site control of the casting machine. Detection limit switches are installed at preset positions on both sides of the track 10 to detect the positions of components such as the mold carrier 20. When the mold carrier 20 moves to a set position, the detection limit switches send a signal to prevent overtravel. The programmable controller (PLC) uses an ABB programmable servo drive as its control core, receiving operation commands from the on-site control box and feedback signals from the detection limit switches and high-precision encoders. After logical operations and processing, it sends control commands to the drive mechanism 40 and other actuators. The high-precision encoder is used to detect the moving speed and position of the mold carrier 20 in real time and feeds the detection signal back to the PLC, forming a closed-loop control. Through this closed-loop control, the PLC can adjust the output of the drive mechanism 40 in real time based on the feedback signal, achieving precise control of the speed and position of the mold carrier 20. Meanwhile, the electrical control system 50 also has manual, automatic and interlock functions. The manual mode can be used for equipment debugging and emergency operation, the automatic mode can realize the automated operation of the pouring process, and the interlock function can prevent conflicts between different operations and ensure the safe operation of the equipment.

[0019] The roller assembly 60 includes a track channel steel 601. The track channel steel 601 is fixedly installed on the rear part of the top surface of the square steel bracket 101. A plurality of rollers 602 are rotatably installed on the rear part of the bottom surface of the track frame 401 through the roller bracket. The rollers 602 are inserted into the track channel steel 601 and roll in cooperation with it. A limiting component 70 is fixedly installed on the front part of the bottom surface of the track frame 401, which is symmetrically arranged with the roller assembly 60. The roller assembly 60 is a crucial support and guide structure for the movement of the railcar frame 401 within the drive mechanism 40. The track channel steel 601, fixed to the rear of the top surface of the square steel bracket 101, provides a specific rolling track for the rollers 602. Several rollers 602, rotatably mounted on the rear bottom surface of the railcar frame 401 via the roller bracket, engage with and roll within the track channel steel 601. When the railcar frame 401 moves under the power of the drive mechanism 40, the rollers 602 roll within the track channel steel 601, providing support for the movement of the railcar frame 401. Simultaneously, the channel-shaped structure of the track channel steel 601 guides the rollers 602, preventing lateral deviation of the railcar frame 401 during movement. The limiting assembly 70, symmetrically arranged with the roller assembly 60 and fixed to the front bottom surface of the railcar frame 401, limits and guides the movement of the railcar frame 401 from the other side. Working together with the roller assembly 60, it ensures the overall stability and accuracy of the movement of the railcar frame 401.

[0020] The limiting component 70 cooperates with the roller component 60 to limit and guide the movement of the railcar frame 401. The I-beam rail 701, symmetrically arranged with the rail channel steel 601 and fixed to the front of the top of the square steel bracket 101, provides a track for the limiting wheels 702. Several evenly distributed connecting seats fixed to the front of the bottom of the railcar frame 401 are used to install axles. The limiting wheels 702, rotatably mounted at the lower end of the axles, work together to clamp the I-beam rail 701. When the railcar frame 401 moves, the limiting wheels 702 and the I-beam rail 701 roll in a coordinated manner. On one hand, the clamping action of the symmetrical limiting wheels 702 effectively restricts the lateral movement of the railcar frame 401, preventing deviation. On the other hand, the rolling action of the limiting wheels 702 reduces the frictional resistance during the movement of the railcar frame 401, ensuring smooth movement.

[0021] The mold 30 is the core component used for casting aluminum-zinc-silicon alloy ingots, consisting of a mold body 301 and lifting cores 302. The top surface of the mold body 301 is open, facilitating the pouring of molten aluminum-zinc-silicon alloy into the mold. The lifting cores 302, fixedly installed on both sides of the bottom surface of the inner wall of the mold body 301, serve two purposes: firstly, during the casting process, they can form specific structures for the alloy ingot (such as lifting holes), facilitating subsequent lifting and handling of the ingot; secondly, the lifting cores 302 can also enhance the structural strength of the mold body 301 to a certain extent, and may also guide the flow and solidification of the alloy liquid, promoting uniform solidification of the ingot. The mold body 301 can cast alloy ingots weighing 1000kg±200kg / ingot, and the mold 30 weighs 1750kg±100kg / piece. This parameter design meets the production requirements of aluminum-zinc-silicon alloy ingots of specific specifications.

[0022] The interior of the vehicle body 201 is hollow, with inlet and outlet water pipes fixedly installed on the outside, forming a closed cooling water jacket structure. During the casting process, the molten aluminum-zinc-silicon alloy liquid is poured into the mold 30, releasing a large amount of heat, causing the temperature of the mold 30 to rise. At this time, cold water is introduced into the interior of the vehicle body 201 through the inlet water pipe. The cold water flows in the closed cooling water jacket, exchanging heat with the vehicle body 201 and absorbing the heat transferred from the mold 30, thereby cooling the mold 30. At the same time, the cooling water jacket also acts as insulation, reducing the diffusion of heat from the mold 30 to the surrounding environment and preventing surrounding equipment from being affected by high temperatures. The water, which has heated up after absorbing heat, is promptly discharged from the vehicle body 201 through the outlet water pipe, ensuring that cooling water continuously enters the vehicle body 201 for cooling and maintaining a good cooling effect.
