Description

Technical Field

[0001] The invention belongs to the technical field of amorphous alloys and relates to a device and method for continuous production of amorphous alloy wires. Background Art

[0002] Amorphous alloy wire is small in size and low in cost. It also has the most significant giant magneto-impedance effect (GMI). When a high-frequency alternating current passes through an amorphous alloy wire, a relatively small axial magnetic field is applied. At this time, the magnetic impedance of the amorphous alloy wire will change dramatically. This change is converted into an electrical signal, which can detect weak magnetic fields. Therefore, amorphous alloy wire is the preferred material for developing GMI magnetic sensors. Compared with traditional magnetic sensors, GMI magnetic sensors have the characteristics of extremely high measurement sensitivity, high response speed, small size, and almost no hysteresis. At the same time, the results are not affected by temperature changes, and have unparalleled advantages in the field of high-sensitivity and high-precision weak magnetic detection.

[0003] The preparation methods of amorphous alloy wires have been mainly divided into three categories: glass-coated spinning, melt-pulling spinning and inner-circle rotary water spinning. Among them, the inner-circle rotary water spinning method is to spray a metal jet into the coolant on the inner surface of a high-speed rotating cylinder to cool and form an amorphous alloy wire. No additional coolant replenishing device is required during the production process, which has the characteristics of low cost, low coolant consumption and environmental friendliness. In addition, the cylinder speed controls the flow rate of the coolant to improve the liquid surface stability and cooling efficiency of the coolant.

[0004] In 2022, Chinese patent CN115870463A disclosed an improved internal circular rotary water spinning equipment, in which a wire clamping unit was added. The linear motion of the straight rod and the sleeve was controlled by a cylinder to realize the opening and closing of the clamping strip, successfully clamp the amorphous alloy wire, and wind it in the V-shaped groove. The equipment has initially realized the continuous preparation and winding of amorphous alloy wire, and improved production efficiency. However, the equipment still has several limitations: first, the driving mechanism of the wire clamping unit is relatively complex, including cylinders, pistons, valves and other components, which increases the equipment cost and maintenance difficulty; second, the equipment lacks relevant devices for the continuous supply of low-temperature coolant. Long-term continuous production will increase the coolant temperature, thereby affecting the quality of the amorphous alloy wire; third, the equipment lacks a feeding device and cannot continuously supply raw materials. Summary of the invention

[0043] As a preferred technical solution, by adjusting the ratio of the thickness of the drum and the length of the central axis of the drum, the winding length of the amorphous alloy wire can be adjusted while the drum is fixedly installed.

[0044] One of the technical solutions of the present invention is to provide a method for continuous production of amorphous alloy wire, which adopts the above-mentioned device to continuously produce amorphous alloy wire, and comprises the following steps:

[0045] During the melting of the master alloy, the motor is started to drive the wheel hub to rotate, and a suitable amount of coolant is added into the wheel hub according to the amorphous forming capacity of the alloy, and a coolant film is formed by the centrifugal force;

[0046] During the production process, the coolant in the wheel hub is sucked through the coolant inlet pipe, and after being cooled by the coolant circulation pump, it is input into the wheel hub through the coolant outlet pipe, so that the coolant always keeps a low temperature;

[0047] According to the amorphous forming ability of the master alloy, the distance between the alloy jet outlet of the material tube and the coolant surface is adjusted through the material tube position control component. After the master alloy is completely melted, high-pressure gas is introduced into the material tube to make the alloy jet ejected into the high-speed rotating coolant, which is quickly cooled and solidified to form amorphous alloy wire;

[0048] At this time, the motor drives the drum wheel to rotate the suction bar just to the coolant just below the direction of the alloy jet, so that the starting section of the formed amorphous alloy wire falls on the suction bar after cooling, and the magnet on the suction bar absorbs the amorphous alloy wire;

[0049] Subsequently, the driving roller is started. Under the action of the driving roller, the connecting wire is converged, and the angle between the suction bar and the first straight rod begins to decrease to substantially zero, and the starting section of the amorphous alloy wire leaves the coolant under the traction of the suction bar; then, the angle between the first straight rod and the second straight rod begins to decrease to substantially zero; finally, the angle between the second straight rod and the groove-shaped bottom surface of the first straight rod begins to decrease to zero, so that the starting section of the amorphous alloy wire is embedded in the drum wheel;

[0050] As the drum rotates, the amorphous alloy wire is formed and wound inside the drum, realizing continuous production.

[0051] As a preferred technical solution, the drum and the hub rotate coaxially and in the same direction, and the rotation speed is set according to the formation time of the amorphous alloy wire, so that the amorphous alloy wire can be collected smoothly.

[0052] Furthermore, after the production starts, the three robotic arms are first controlled in a coordinated manner to accurately align the material tube with the selected smelting position in the hub, while ensuring that the distance between the tube column surface of the material tube and the surface of the drum center axis of the drum is 30-40cm;

[0053] The screw driving component is started to lower the material tube, and the alloy jet outlet of the material tube is lowered to 20-30 mm from the inner wheel surface of the hub, and the screw driving component is shut down to stop the lowering of the material tube; the height of the alloy jet outlet of the material tube is determined by comprehensively considering factors such as the amorphous forming ability of the alloy and the ejection pressure, so that the alloy jet is ejected into the coolant and condensed to form an amorphous alloy wire with a completely amorphous structure;

[0054] Subsequently, the three robotic arms are coordinated and controlled again to drive the material tube to move linearly in the thickness direction of the drum until the material tube stops at a position 10-15 cm away from the outer contour surface of the drum; the position of the material tube should be set so that the starting section of the amorphous alloy wire can be smoothly clamped, while avoiding collision between the drum and the material tube during high-speed rotation.

[0055] Furthermore, the prepared master alloy block is put into the feeding mechanism, and enters the material pipe after passing through the conveying pipe;

[0056] The induction heating motor is started to generate an alternating magnetic field in the induction coil, and the master alloy is heated to a temperature 100-200°C above the melting point of the master alloy and kept at this temperature for 5-10 minutes to completely melt the master alloy;

[0057] The wheel hub is driven to rotate at a speed of 300-500rpm, and a cooling liquid film with a thickness of 10-15mm is formed through the action of centrifugal force.

[0058] As a preferred technical solution, during the heating process, an infrared thermometer is used to detect the temperature of the master alloy in real time to ensure that the temperature meets the requirements.

[0059] As a preferred technical solution, the gas valve is opened, high-pressure gas is introduced, the gas pressure is adjusted, and the alloy jet is ejected.

[0060] As a preferred technical solution, after the production process is completed, the power supply of the induction heating motor is cut off to stop heating the master alloy;

[0061] Next, the robot arm is operated to move the material tube away from the production position;

[0062] After the material tube is cooled and cleaned, it is repositioned to its original position to prepare for the next production cycle;

[0063] Then, the motor driving the drum and the hub is turned off to stop the rotation of the drum and the hub;

[0064] After the equipment stops completely, take out the wound amorphous alloy wire from the drum for subsequent processing or direct application;

[0065] Finally, drain and clean the coolant in the amorphous alloy wire cooling assembly to ensure that the inside of the equipment is clean and free of residue.

[0066] In view of the current status of the inner circle rotary water spinning technology, the amorphous alloy wire winding assembly including the amorphous alloy wire suction mechanism was redesigned on the basis of the existing technology, and a master alloy melting and injection assembly including a feeding function and an amorphous alloy wire cooling assembly including coolant circulation for temperature control were added to integrate a new type of amorphous alloy wire continuous production device.

[0067] Compared with the prior art, the present invention has the following beneficial effects:

[0068] (1) The temperature of the coolant is controllable: the present invention adds an amorphous alloy wire cooling assembly, uses a coolant input pipe to absorb the coolant in the wheel hub, inputs the coolant into the coolant circulation pump for cooling, and then inputs the coolant into the wheel hub through the coolant output pipe to maintain the temperature of the coolant, ensure the formation of the amorphous structure, and increase the continuous production capacity of the amorphous alloy wire;

[0069] (2) Simplified wire collection structure: The present invention eliminates components such as cylinders and pistons, uses a driving roller as a power source to control the movement of the straight rod and the suction strip, and realizes the automatic collection of amorphous alloy wires, which greatly simplifies the wire collection structure and reduces the cost of the device and the difficulty of maintenance;

[0070] (3) High productivity: The present invention adds a hopper to achieve continuous supply of raw materials, and cooperates with the amorphous alloy wire winding assembly and the amorphous alloy wire cooling assembly to greatly improve production efficiency and achieve continuous production of amorphous alloy wire;

[0071] (4) Wide range of production types: According to the amorphous forming capacity of the master alloy, the height of the alloy jet outlet of the material pipe from the coolant level is flexibly adjusted through the material pipe position control component, thereby changing the residence time of the alloy jet in the air, ensuring that the amorphous alloy wire obtains a sufficient cooling rate to form a completely amorphous structure;

[0072] (5) Safety and environmental protection: The coolant of the present invention is recycled, which reduces coolant consumption and reduces environmental pollution. BRIEF DESCRIPTION OF THE DRAWINGS

[0088] Example:

[0089] A continuous production device for amorphous alloy wire, such as Figure 1 As shown, it includes a master alloy melting and injection assembly, a material pipe position control assembly, an amorphous alloy wire cooling assembly and an amorphous alloy wire winding assembly;

[0090] like Figure 2 As shown, the master alloy smelting and injection assembly includes a feeding mechanism, a material pipe 10 and a master alloy heating mechanism. The feeding mechanism feeds raw materials, and the feeding mechanism is connected with the material pipe 10 through a conveying pipe. The material pipe 10 is provided with an interface to pass high-pressure gas to spray alloy jets. The feeding mechanism uses a hopper 12, and the material of the material pipe 10 is quartz. The high-pressure gas uses high-pressure nitrogen. The master alloy heating mechanism heats the material pipe 10. The feeding mechanism is used to feed the master alloy into the material pipe 10 to continuously produce amorphous alloy wire 34. The material pipe 10 is used to store and melt the master alloy during the production process, and to spray the alloy jet. Compared with the prior art, the master alloy smelting and injection assembly connects the feeding mechanism with the material pipe 10, which can continuously supply raw materials and greatly improve the production capacity of amorphous alloy wires.

[0091] The master alloy heating mechanism includes an induction heating motor 13 and an induction coil 11. The induction heating motor 13 is connected to the induction coil 11. The material tube 10 is arranged in the induction coil 11 for heating. The induction heating motor 13 is arranged on a tray 14. The induction heating motor 13 is used to provide a heat source for melting the master alloy. The induction coil 11 is used to generate an alternating magnetic field to melt the master alloy.

[0100] A method for continuous production of amorphous alloy wire, using the above device to carry out Fe 75 Si 10 B 15 The specific steps for continuous production of amorphous alloy wire are as follows:

[0101] After the production starts, the three mechanical arms are first controlled in coordination to accurately align the material tube 10 with the selected smelting position in the hub 3, while ensuring that the distance between the pipe column surface of the material tube 10 and the surface of the drum center axis 31 of the drum 7 is 35 cm;

[0102] The screw driving component 15 is started to lower the material tube 10, and the alloy jet outlet of the material tube 10 is lowered to 25 mm from the inner wheel surface of the hub 3, and the screw driving component 15 is shut down to stop the material tube 20 from descending; the height of the alloy jet outlet of the material tube 10 is determined by comprehensively considering factors such as the alloy amorphous forming ability and the ejection pressure, so that the alloy jet is ejected into the coolant 33 and condensed to form an amorphous alloy wire 34 with a completely amorphous structure;

[0103] Subsequently, the three robotic arms are coordinated and controlled again to drive the material tube 10 to move linearly in the thickness direction of the drum 7 until the material tube 10 stops at a position 13 cm away from the outer contour surface of the drum 7; the position of the material tube 10 should be set in such a way that the starting section of the amorphous alloy wire 34 can be smoothly clamped, while avoiding the collision between the drum 7 and the material tube 10 during high-speed rotation;

[0104] The prepared master alloy block is put into the hopper 12, and then enters the alloy jet nozzle 10 with a nozzle aperture of 150 μm and a nozzle length of 1.5 mm after passing through the conveying pipe;

[0105] The induction heating motor 13 is started to generate an alternating magnetic field in the induction coil 11, and the master alloy is heated to a temperature of 150° C. above the melting point of the master alloy and kept at this temperature for 8 minutes, so that the master alloy is completely melted;

[0106] During the heating process, an infrared thermometer is used to detect the temperature of the master alloy in real time to ensure that the temperature meets the requirements;

[0107] Open the gas valve, introduce high-pressure nitrogen, adjust the gas pressure, and spray out the alloy jet;

[0108] During the melting of the master alloy, the motor 5 is started to drive the wheel hub 3 to rotate at a speed of 400 rpm, and a suitable amount of coolant 33 is added into the wheel hub 3 according to the amorphous forming ability of the alloy, and a coolant film with a thickness of 13 mm is formed by the centrifugal force;

[0109] During the production process, the coolant 33 in the wheel hub 3 is sucked by the coolant input pipe 29, input into the coolant circulation pump 27, and then input into the wheel hub 3 through the coolant output pipe 28 after cooling, so that the coolant 33 is always kept at a low temperature;

[0110] The alloy jet is ejected into the high-speed rotating coolant 33, and is rapidly cooled and solidified to form an amorphous alloy wire 34;

[0111] At this time, the motor 5 drives the drum 7 to rotate the suction bar 9 to the coolant 33 just below the direction of the alloy jet, so that the starting section of the formed amorphous alloy wire 34 falls on the suction bar 9 after cooling, and the magnet 35 on the suction bar 9 absorbs the amorphous alloy wire 34;

[0112] The drum 7 and the hub 3 rotate in the same direction and coaxially, and the rotation speed is set according to the time when the amorphous alloy wire 34 is formed, so that the amorphous alloy wire 34 can be collected smoothly;

[0113] Subsequently, the driving roller 26 is started. Under the action of the driving roller 26, the connecting wire 36 is converged, and the angle between the suction strip 9 and the first straight rod 8 begins to decrease to substantially zero, and the starting section of the amorphous alloy wire 34 leaves the cooling liquid 33 under the traction of the suction strip 9; then, the angle between the first straight rod 8 and the second straight rod 6 begins to decrease to substantially zero; finally, the angle between the second straight rod 6 and the groove-shaped bottom surface of the first straight rod 8 begins to decrease to zero, so that the starting section of the amorphous alloy wire 34 is embedded in the drum 7;

[0114] As the drum 7 rotates, the amorphous alloy wire 34 is formed and wound inside the drum 7, thus achieving continuous production.

[0115] After the production process is completed, the power supply of the induction heating motor 13 is cut off to stop heating the master alloy;

[0116] Next, the robot arm is operated to move the material tube 10 away from the production position;

[0117] After the material tube 10 is cooled and cleaned, the material tube 10 is repositioned to the initial position to prepare for the next production cycle;

[0118] Then, the motor 5 driving the drum 7 and the wheel hub 3 is turned off to stop the rotation of the drum 7 and the wheel hub 3;

[0119] After the equipment is completely stopped, the wound amorphous alloy wire 34 is taken out from the drum 7 for subsequent processing or direct application;

[0120] Finally, the coolant 33 in the amorphous alloy wire cooling assembly is drained and cleaned to ensure that the inside of the equipment is clean and free of residue.
