Description

Technical Field

[0001] This invention relates to the field of metal material processing technology, specifically to a beryllium aluminum alloy sheet preparation equipment and method. Background Technology

[0002] Beryllium-aluminum alloys are characterized by their light weight, high specific strength, high specific stiffness, good thermal stability, high toughness, and corrosion resistance. They combine the low density of beryllium with the easy machinability of aluminum, and have been widely used in aerospace, computer manufacturing, automotive industry and other fields. They have become a new material that has attracted much attention in various fields.

[0003] Existing technologies lack deep processing steps for metal raw materials during raw material preparation, resulting in the direct melting of metal particles of different diameters. This method is prone to causing stratification due to the characteristics of beryllium and aluminum, leading to different overall metal content in the alloy.

[0004] Meanwhile, existing technologies mostly involve simple stirring during the mixing process, lacking protection against the powder flying during stirring; at the same time, the smelting process requires maintaining a vacuum state, which leads to the long-term operation of vacuum equipment, resulting in excessive energy consumption.

[0015] Preferably, the top of the side box is connected to the first air pipe, and a dust filter screen is provided at the connection between the side box and the first air pipe to prevent material from being blocked.

[0016] Preferably, the lifting ring has a spiral upward-shaped filter structure, and a rubber gasket is provided at the contact point between the outer wall of the lifting ring and the material cylinder.

[0017] Preferably, the bottom outer side of the drive shaft is provided with three sets of stirring blades, and the stirring blades are designed to be inclined at an angle of 60 degrees.

[0018] Preferably, the method for preparing the beryllium aluminum alloy sheet is characterized by comprising the following steps:

[0019] Step 1: Add lumps or powdered aluminum into the feeding cylinder. Control the first motor via the control panel to drive the drive roller and crushing roller to rotate and crush the material. Then, add beryllium powder and plasticizer into the feeding cylinder in sequence. The ratio of beryllium powder, plasticizer and aluminum powder is 6.5:0.5:3. At this time, the drive roller and crushing roller crush the various raw materials. Gravity causes the crushed raw material powder to fall onto the lifting ring, which is in the form of a filter screen.

[0020] Step 2: The second motor is controlled to operate, which drives the lifting ring through the transmission belt to lift the material. At this time, the metal raw materials with qualified particle diameter will fall into the storage cylinder through the lifting ring, and the transmission shaft drives the stirring paddle to stir the various materials. The metal particles with unqualified diameter will be driven upward to the discharge plate by the transmission action of the lifting ring, so that they can be crushed multiple times until the particle diameter is qualified. Here, the qualified particle diameter is set to 200 mesh.

[0021] Step 3: During the crushing process, inert gas connected to the outside can be introduced into the reversing valve through the first air pipe. The inert gas is then blown into the storage cylinder and the feeding cylinder through the reversing valve and the guide pump. The inert gas mentioned here can be nitrogen or helium. At this time, the properties of the inert gas can prevent the metal powder from flying and causing powder explosion. The airflow of the inert gas is discharged through the air hole set on the top of the side box, reducing the phenomenon of discharge from the feed port.

[0022] Step 4: After the powder preparation process is completed, the electromagnetic clutch can be controlled through the control panel to operate, so that the rotating drive shaft can drive the first filter screen to rotate through the electromagnetic clutch. This causes the holes of the first and second filter screens to overlap, thus feeding the prepared powder and reducing the phenomenon of stratification between different solutions.

[0023] Step 5: During the mixing process, the operator first controls the vacuum pump through the control panel to draw gas from the inside of the melting furnace and gradually create a vacuum. When the vacuum pump finishes drawing, the operator controls the second check valve through the control panel to allow the inert gas flowing inside the storage cylinder to flow into the compensation cylinder through the second check valve. This causes the inert gas to accumulate inside the compensation cylinder and push the piston plate to move backward.

[0024] Step Six: At this point, the piston plate displacement pushes the compression spring and pressure sensor to contract, thereby causing the pressure sensor to detect the total amount of gas at the front end of the piston plate. When the overall volume reaches the standard value, the pressure sensor sends an electrical signal to the control panel to control the first one-way valve to open, so that the inert gas can flow into the melting furnace, and the melting, cooling and forming processes can be carried out under the protection of the inert gas.

[0025] The present invention has the following advantages: The present invention provides an improved method for preparing beryllium aluminum alloy plates, which, compared with similar equipment, has the following improvements:

[0027] The equipment and method for preparing beryllium aluminum alloy plates described in this invention, by setting a transmission component at the bottom of the feeding cylinder, controls a second motor to drive the transmission shaft and lifting ring and other components to rotate through the transmission belt, thereby lifting and mixing the crushed material through the lifting ring and stirring paddle, which is beneficial to improving the guiding and mixing effect of metal distribution;

[0046] The stirring assembly 387 includes an electromagnetic clutch 3871. The electromagnetic clutch 3871 is rotatably mounted on the bottom of the drive shaft 383. The electromagnetic clutch 3871 is bolted to the inner through-hole of the first filter screen 3872, providing a limiting effect for the installation of the first filter screen 3872.

Electrical connection provides power to the electromagnetic clutch 3871, the guide pump 3875, and the reversing valve 3876. The guide pump 3875, which plays a guiding role, is fixedly installed at the right end opening of the storage cylinder 3874 through a connecting pipe. The reversing valve 3876, which plays a reversing role, is installed on the right end pipe of the guide pump 3875. The first gas pipe 3877 is installed on the rear end pipe of the reversing valve 3876. The right end of the smelting furnace 2 is connected to the bottom outlet pipe of the storage cylinder 3874 through a connecting pipe, so that the storage cylinder 3874 provides a guiding effect for the smelting furnace 2.

[0047] The top of the side box 32 is connected to the first air pipe 3877, and a dust filter screen is provided at the connection between the side box 32 and the first air pipe 3877 to block the material.

[0048] The lifting ring 384 has a spiral upward filter structure, and a rubber gasket is provided at the contact point between the outer wall of the lifting ring 384 and the material cylinder 31. The lifting ring 384 provides a material lifting effect.

[0049] Three sets of stirring paddles 386 are provided on the bottom outer side of the drive shaft 383, and the stirring paddles 386 are designed with an angle of 60 degrees. The drive shaft 383 provides a transmission effect for the stirring paddles 386.

[0050] The working principle of the beryllium aluminum alloy sheet preparation equipment based on Example 1 is as follows:

[0051] When using this device, first place it in the work area, then connect it to an external power source to provide the power required for its operation.

[0052] First, during the preparation of beryllium-aluminum alloy, the workers add block or powdered aluminum metal into the feeding cylinder 31, and control the first motor 33 through the control panel 6 to drive the drive roller 34 and the crushing roller 35 to rotate and perform crushing work. Then, beryllium powder and plasticizer are added into the feeding cylinder 31 in sequence. Here, the ratio of beryllium powder, plasticizer and aluminum powder is 6.5:0.5:3. At this time, the drive roller 34 and the crushing roller 35 crush the various raw materials, and the crushed raw material powder falls onto the lifting ring 384 by gravity. The lifting ring 384 is in the shape of a filter screen.

[0053] Second, by controlling the second motor 381 to work, it drives the lifting ring 384 to lift the material through the transmission belt 382. At this time, the metal raw materials with qualified particle diameter will fall into the storage cylinder 3874 through the lifting ring 384, and drive the stirring paddle 386 through the transmission shaft 383 to stir the various materials, which is beneficial to improve the mixing effect of the prepared materials. The metal particles with unqualified diameter will be driven upward to the feeding plate 37 by the transmission action of the lifting ring 384, so that they can be crushed multiple times until the particle diameter is qualified. Here, the qualified particle diameter is set to 200 mesh.

[0054] Third, during the crushing process, inert gas connected to the outside can be introduced into the reversing valve 3876 through the first air pipe 3877, and the inert gas can be blown into the storage cylinder 3874 and the feeding cylinder 31 through the reversing valve 3876 and the guide pump 3875. The inert gas mentioned here can be nitrogen or helium. At this time, the characteristics of the inert gas can prevent the metal powder from flying and causing powder explosion. The airflow of the inert gas can be discharged through the air hole set at the top of the side box 32, reducing the phenomenon of being discharged from the feed port.

[0055] Fourth, after the powder preparation process is completed, the electromagnetic clutch 3871 can be controlled by the control panel 6 to operate, so that the rotating drive shaft 383 can drive the first filter screen 3872 to rotate through the electromagnetic clutch 3871. This causes the holes of the first filter screen 3872 and the second filter screen 3873 to overlap and feed the prepared powder. This is beneficial to improve the rapid melting and mixing of fine powder during mixing and can reduce the phenomenon of stratification between different solutions.

[0056] Example 2:

[0057] Please see Figure 1 and Figure 8The present invention provides a beryllium aluminum alloy plate preparation device. Compared with the first embodiment, this embodiment further includes: a compensation component 4. The compensation component 4 includes a quick-connect pipe 41. The top opening pipe of the melting furnace 2 is equipped with a quick-connect pipe 41 that serves as a quick connection. The right end of the quick-connect pipe 41 is fixedly installed with a flow control valve 42 through a connecting pipe. The flow control valve 42 provides flow monitoring for the quick-connect pipe 41. The right opening pipe of the flow control valve 42 is equipped with a second gas pipe 43.

[0058] The bottom of the second air pipe 43 is connected to the top pipe of the first one-way valve 44. The first one-way valve 44 is bolted to the front side of the top of the compensation cylinder 45. A second one-way valve 46 is installed on the front pipe of the compensation cylinder 45 to guide the flow. The second one-way valve 46 provides an inlet effect for the compensation cylinder 45. A piston plate 47 is slidably arranged on the inner wall of the compensation cylinder 45. A pressure spring 48 is fixedly installed at the rear end of the piston plate 47 to reset the pressure spring 48. A pressure sensor 49 is fixedly installed at the rear end of the piston plate 47 to detect the pressure. The pressure sensor 49 provides detection of the air pressure at the front end of the piston plate 47. The flow control valve 42, the first one-way valve 44, the second one-way valve 46, and the pressure sensor 49 are all electrically connected to the control panel 6 to provide power to the flow control valve 42, the first one-way valve 44, the second one-way valve 46, and the pressure sensor 49.

[0059] In this embodiment:

[0060] First, during the mixing process, the operator controls the vacuum pump 5 through the control panel 6 to operate, thereby drawing gas from the inside of the melting furnace 2 to gradually form a vacuum. When the vacuum pump 5 completes the drawing work, the operator controls the second check valve 46 through the control panel 6 to operate, so that the inert gas flowing inside the storage cylinder 3874 can flow into the compensation cylinder 45 through the second check valve 46, thereby causing the inert gas to accumulate inside the compensation cylinder 45 and push the piston plate 47 to move backward.

[0061] Secondly, at this time, the displacement of the piston plate 47 pushes the compression spring 48 and the pressure sensor 49 to contract, thereby causing the pressure sensor 49 to detect the total amount of gas at the front end of the piston plate 47. When the overall volume reaches the standard value, the pressure sensor 49 sends an electrical signal to the control panel 6 to control the first one-way valve 44 to open, so that the inert gas can flow into the interior of the melting furnace 2, and the melting, cooling and forming processes can be carried out under the protection of the inert gas.

[0062] This invention provides an improved method for preparing beryllium aluminum alloy sheets. A first motor 33 drives a drive roller 34 and a crushing roller 35 to crush various materials. A speed sensor 36 monitors the rotational speed of the crushing roller 35, thereby improving the repeatability and effectiveness of the crushing process for metal particles. A second motor 381 drives a drive shaft 383 and a lifting ring 384 via a transmission belt 382. The lifting ring 384 and a stirring paddle 386 then lift and mix the crushed materials, improving the guiding and mixing effect of the metal distribution. An electromagnetic clutch 3871 controls the process. The drive shaft 383 is provided with an adsorption action, which drives the first filter screen 3872 to rotate and discharge material through the second filter screen 3873. The discharge action is protected by introducing inert gas through the guide pump 3875 and the reversing valve 3876. Inert gas is introduced into the compensation cylinder 45 through the second one-way valve 46. The piston plate 47 is pushed to squeeze the compression spring 48 and the pressure sensor 49 respectively. The pressure sensor 49 monitors the amount of gas introduced through the pressure of the piston plate 47, and the elasticity of the compression spring 48 provides a reset action for the piston plate 47, which helps to improve the gas compensation of the smelting process.

9. The equipment for preparing beryllium aluminum alloy plates according to claim 2, characterized in that: The drive shaft (383) has three sets of stirring paddles (386) on its outer bottom, and the stirring paddles (386) are designed with an angle of 60 degrees.

10. A method of using the equipment for preparing beryllium aluminum alloy plates according to any one of claims 4 to 9, characterized in that: Includes the following steps: Step 1: Add block or powdered aluminum metal into the feeding cylinder (31), and control the first motor (33) through the control panel (6) to drive the drive roller (34) and crushing roller (35) to rotate and perform crushing work. Then, add beryllium powder and plasticizer into the feeding cylinder (31) one after another. The ratio of beryllium powder, plasticizer and aluminum powder is 6.5:0.5:

3. At this time, the drive roller (34) and crushing roller (35) crush the various raw materials, and the crushed raw material powder falls onto the lifting ring (384) by gravity. The lifting ring (384) is in the shape of a filter screen. Step 2: The second motor (381) is controlled to work, so that it drives the lifting ring (384) to lift the material through the transmission belt (382). At this time, the metal raw materials with qualified particle diameter will fall into the storage cylinder (3874) through the lifting ring (384), and the stirring paddle (386) will drive the various materials to stir through the transmission shaft (383). The metal particles with unqualified diameter will be driven upward to the feed plate (37) by the transmission action of the lifting ring (384), so that they can be crushed multiple times until the particle diameter is qualified. Here, the qualified particle diameter is set to 200 mesh. Step 3: During the crushing process, inert gas connected to the outside can be introduced into the reversing valve (3876) through the first air pipe (3877), and the inert gas can be blown into the storage cylinder (3874) and the feeding cylinder (31) through the reversing valve (3876) and the guide pump (3875). The inert gas mentioned here can be nitrogen or helium. At this time, the characteristics of the inert gas can prevent the metal powder from flying and causing powder explosion. The airflow of the inert gas can be discharged through the air hole set on the top of the side box (32) to reduce the phenomenon of being discharged from the feed port. Step 4: After the powder preparation process is completed, the electromagnetic clutch (3871) can be controlled by the control panel (6) to work, so that the rotating drive shaft (383) can drive the first filter screen (3872) to rotate through the electromagnetic clutch (3871), so that the holes of the first filter screen (3872) and the second filter screen (3873) overlap to feed the prepared powder, which can reduce the phenomenon of stratification between different solutions; Step 5: During the mixing process, the operator first controls the vacuum pump (5) through the control panel (6) to operate, so that the vacuum pump (5) draws the gas inside the melting furnace (2) and gradually forms a vacuum. When the vacuum pump (5) completes the drawing work, the operator controls the second check valve (46) through the control panel (6) to operate, so that the inert gas flowing inside the storage cylinder (3874) can flow into the compensation cylinder (45) through the second check valve (46), so that the inert gas accumulates inside the compensation cylinder (45) and pushes the piston plate (47) to move backward. Step 6: At this time, the displacement of the piston plate (47) pushes the compression spring (48) and the pressure sensor (49) to contract, so that the pressure sensor (49) detects the total amount of gas at the front end of the piston plate (47). When the overall volume reaches the standard value, the pressure sensor (49) sends an electrical signal to the control panel (6) to control the first one-way valve (44) to open, so that the inert gas can flow into the interior of the melting furnace (2), and the melting, cooling and forming processes can be carried out under the protection of the inert gas.
