Description

Technical Field

[0001] The invention relates to the technical field of aluminum-iron melting casting plate production, and in particular to a manufacturing method and a manufacturing device of an aluminum-iron melting casting plate. Background Art

[0002] Aluminum-iron cast brake discs are made of cast iron and aluminum, which can reduce weight by about 20%, significantly reduce energy consumption and emissions, reduce the unsprung weight of the vehicle, and improve thermal deformation resistance by up to 70%, reduce drag torque, and reduce the possibility of shaking. The Chinese patent publication number CN118204478A discloses a new method for preparing a lightweight brake disc with an iron (steel) / aluminum layered composite structure, including optimizing and regulating the forming of aluminum alloy, wherein the Cr content is 0.5-0.8wt%, the Mn content is 1.0-1.5wt%, the Ti content is 2.0wt%, and the Nb content is 0.5wt%; using Inert gas assisted pressure casting is used to achieve composite structure forming. First, the steel brake surface component is placed at the bottom of the graphite mold, and the aluminum alloy raw material with optimized composition is placed on the upper part. When the vacuum degree is less than 0.5Pa, the whole is heated to 800°C and kept warm for 30 minutes, cooled to 720°C and kept warm for 20 minutes, and then pressurized to 3.0MPa with Ar gas and kept at pressure for 15 minutes; after forming is completed, controlled cooling is carried out, the temperature is reduced from 720°C to 580-600°C in 60 minutes, and kept warm for 20 minutes, and the temperature is reduced from 600°C to 300-320°C in 180 minutes, and kept warm for 40 minutes, and finally cooled with the furnace.

[0003] In the above-mentioned prior art, when the aluminum-iron cast brake disc is cast, the pre-proportioned aluminum alloy base material and gray iron need to be process controlled during the casting process, that is, the aluminum alloy base material gray iron and trace alloys are added in trace amounts to adjust the aluminum-iron ratio during the casting process to achieve the purpose of improving the quality of the cast disc. During this process, the furnace needs to be opened for process control filling. This process will cause air to enter and reduce the temperature of the furnace casting process, which is not conducive to the casting process. For this reason, a method for manufacturing an aluminum-iron cast disc and a manufacturing device thereof are proposed. Summary of the invention

[0004] In order to solve the problem that when casting an aluminum-iron cast brake disc, the pre-proportioned aluminum alloy base material and gray iron need to be process controlled during the casting process, that is, the aluminum alloy base material gray iron and trace alloys are added in trace amounts to adjust the aluminum-iron ratio during the casting process to achieve the purpose of improving the quality of the cast disc. In this process, the furnace needs to be opened for process control filling, and this process will cause air to enter and reduce the temperature of the furnace casting process, which is not conducive to the casting process. The present invention provides a method for manufacturing an aluminum-iron cast disc and a manufacturing device thereof.

[0005] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions: A manufacturing device for an aluminum-iron smelting plate comprises a material table, wherein a furnace mechanism for uniformly heating the aluminum-iron is arranged on the bottom side of the material table, a cover mechanism for stirring and isolating air is arranged on the top side of the material table, a process feeding mechanism for sealing a process control filler under the cover mechanism is installed on the material table, and the process feeding mechanism is located on the bottom side of the cover mechanism, and a rotating mechanism for dumping materials is installed on the material table, and the rotating mechanism is located on one side of the process feeding mechanism. When the aluminum-iron smelting plate is smelted and cast, an aluminum alloy substrate and gray iron are placed in a furnace mechanism according to a proportion and heated, and during the heating process, the molten aluminum-iron liquid is stirred and an inert gas is introduced to isolate the air while being sealed by the cover mechanism. When it is necessary to adjust the composition for process control, the process feeding mechanism is rotated to add the required process control material into the rotating mechanism, and when the required amount of control material is reached, the rotating mechanism is rotated to put the material into the furnace mechanism to complete the process control.

[0006] Furthermore, the furnace mechanism includes a graphite crucible, which is movably installed on a material table. A heating and thermal insulation layer is installed on the graphite crucible. The heating and thermal insulation layer is made of ceramic fiber cotton. A resistance wire is installed on the heating and thermal insulation layer. Through the setting of the graphite crucible, the graphite can effectively withstand the high temperature environment and does not chemically react with the alloy. By heating the thermal insulation layer and the evenly wound resistance wire, stable and sufficient heat can be generated, which is beneficial to the melting and casting of aluminum iron liquid.

[0007] Furthermore, the cover plate mechanism includes a lifting cover, which is movably installed on the material table. A stirring paddle is rotatably installed on the lifting cover, and the stirring paddle is made of graphite. An inert gas pipe is installed on the lifting cover, and an air port is opened on the inert gas pipe. During the aluminum-iron smelting process, inert gas is continuously introduced into the surface of the aluminum-iron liquid to isolate the air and prevent the air from oxidizing the aluminum-iron liquid. At the same time, the stirring paddle is used to stir the aluminum-iron liquid during the smelting process to prevent the aluminum-iron liquid from stratifying, which is conducive to a uniform smelting process.

[0008] Furthermore, the inert gas pipe is made of an enameled steel pipe, which has high temperature resistance and corrosion resistance, and prevents the inert gas pipe from being deformed.

[0009] Furthermore, the process feeding mechanism includes a mounting seat, which is mounted on a material table, a rotating shaft is rotatably mounted on the mounting seat, a connecting plate is mounted on the rotating shaft, a fixed material trough is mounted on the connecting plate, a movable push groove is slidably mounted on the fixed material trough, a cylinder is mounted on the mounting seat, the main shaft of the cylinder is located on one side of the movable push groove, a motor is mounted on the mounting seat, the main shaft of the motor is mounted on the rotating shaft, and the motor is started. Trace alloy powder and aluminum-iron powder required for aluminum-iron smelting are respectively placed in the enclosed space formed by the three fixed material troughs and the movable push groove. When it is necessary to add corresponding materials for process control ratio, the motor is started, and the motor drives the rotating shaft to rotate. The rotation of the rotating shaft drives the corresponding fixed material trough to rotate to one side of the cylinder. The cylinder is started to push out the movable push groove on the corresponding fixed material trough, and the required material is pushed out during the pushing process of the movable push groove.

[0010] Furthermore, a limit slide rod is installed on the fixed material trough, and a limit slider is installed on the movable push groove. A sliding hole is opened on the limit slider, and the limit slide rod is slidably installed in the sliding hole. A spring is movably sleeved on the limit slide rod, and the spring is installed on the limit slider. The setting of the limit slider and the limit slide rod facilitates the sliding of the movable push groove on the fixed material trough. At the same time, under the action of the restoring force of the spring, when the cylinder is reset, the movable push groove is driven to reset, which is convenient for next use and improves the ease of use of the structure.

[0011] Furthermore, the rotating mechanism includes a rotating rod, a rotating hole is opened on the material table, the rotating rod is rotatably installed in the rotating hole, a beveled material trough is installed on the rotating rod, a pressure sensor is installed on the bottom side of the beveled material trough, the beveled material trough is located on the bottom side of the fixed material trough, an electric cylinder is installed on the material table, the main shaft of the electric cylinder is in contact with the beveled material trough, the electric cylinder is electrically connected to the pressure sensor, the material pushed out through the movable pushing groove enters the beveled material trough, and the weight is controlled by the pressure sensor on the beveled material trough. When the required material weight is reached, the cylinder stops pushing the movable pushing groove and resets, and at the same time the pressure sensor transmits an electrical signal to the electric cylinder, the electric cylinder extends out to drive the beveled material trough to rotate on the material table, dumps the required material into the graphite crucible and then resets, completing the process control in the closed state, preventing the melting and casting temperature and air from entering when the lifting cover is opened, ensuring the normal progress of the melting and casting process, and improving the practicability and ease of use of the equipment.

[0012] A method for manufacturing an aluminum-iron smelting casting plate comprises the following steps: Step (1) placing a GG20HC-L model grey cast iron blank in a cupola and heating it to 1400-1450° C. for melting, and after melting, the molten iron flows into a mold of a target size for casting at a casting temperature of 1300-1380° C., and after casting and cooling, grey cast iron is obtained; Step (2) grinding the edges of the obtained gray iron and A356-T6 aluminum alloy substrates and removing excess by means of a horizontal lathe; Step (3) placing the gray iron and aluminum alloy substrate into a graphite crucible according to a ratio, heating to 1500-1600° C. for aluminum-iron smelting and casting, performing process control during the smelting and casting, placing the target molten aluminum-iron liquid into a brake disc mold and cooling it to obtain an aluminum-iron smelting disc; The order of feeding in step (3) is to first feed the aluminum alloy substrate and then feed the gray iron. Since the density and melting point of the aluminum alloy substrate are lower than those of the gray iron, the molten aluminum alloy substrate and the gray iron are prevented from being separated during the casting process, resulting in uneven casting. By first adding the aluminum alloy substrate, the aluminum alloy substrate is evenly cast with the gray iron during the melting process of the aluminum alloy substrate during the heating process, thereby improving the casting effect.

[0013] The process control of step (3) is to start the motor to drive the rotating shaft to rotate, thereby driving the fixed material trough corresponding to the required material to rotate to one side of the cylinder, and start the cylinder to push the movable push trough to slide on the fixed material trough and add the required material into the oblique material trough. When the target control amount is reached, the pressure sensor feeds back an electrical signal to the electric cylinder, and the electric cylinder drives the oblique material trough to rotate and dumps the required material into the graphite crucible; Step (4) preparing the aluminum-iron molten casting disc blank and subjecting it to heat treatment; The heat treatment in step (4) is performed by heating the aluminum-iron molten casting plate to 450-550° C. for homogenization annealing, then cooling it to 200-350° C. for stress relief annealing, and finally heating the aluminum-iron molten casting plate to 400-500° C. and placing it in a coolant for cooling and quenching; Step (5) the aluminum-iron casting plate after standing quenching is subjected to aging treatment; Step (6) Precision turning and drilling of the aluminum-iron molten cast plate.

[0014] The beneficial effects of the present invention are as follows: The present invention, through the arrangement of movable push troughs, fixed troughs, oblique-mouth troughs, etc., realizes process control during the smelting and casting of the aluminum-iron smelting casting plate. While maintaining the smelting and casting sealed state, process control can be achieved through the movement of the corresponding fixed troughs and the quantitative amount of the oblique-mouth troughs, thereby preventing air from entering to oxidize the molten aluminum-iron, facilitating the continuous heating and smelting and casting process, and improving the convenience and practicality of the equipment.

[0015] The present invention prevents the molten aluminum alloy substrate and the gray iron from being separated and unevenly cast during the casting process by first adding the aluminum alloy substrate and then the gray iron, and improves the casting effect by first adding the aluminum alloy substrate so that the aluminum alloy substrate is evenly cast with the gray iron during the melting process of the aluminum alloy substrate during the heating process.
