Description

Technical Field

[0001] The invention relates to the technical field of eliminating impurity gases in high-temperature molten metal, in particular to a hydraulic vibration degassing device for mechanical casting. Background Art

[0002] In the field of mechanical casting, the quality and performance of castings are often directly affected by their internal pores and impurity content. With the continuous improvement of product quality requirements in modern industry, especially in the field of high-end casting, the control of bubbles and impurities in molten metal has reached unprecedented strict standards. This is because these tiny pores and impurities not only affect the appearance quality of castings, but are also likely to cause significant damage to their mechanical properties and durability, thus affecting the service life and market competitiveness of products.

[0003] After searching, it was found that the prior art announcement number is CN115007840B, which discloses a hydraulic vibration degassing device for mechanical casting, including a bracket, characterized in that: a vibration platform is provided on the base of the bracket, a hydraulic lifting and adjusting mechanism is provided on the upper part of the bracket, an inert gas control mechanism is provided in the middle part of the bracket, and the hydraulic telescopic rod of the hydraulic lifting and adjusting mechanism is connected to the inert gas output pipe of the inert gas control mechanism, and the inert gas output pipe is arranged above the vibration platform. The coordinated work of various parts of this design invention can realize degassing for castings of different shapes and sizes, and can flexibly select and determine the number of gas pipes that need to be inserted into the liquid metal and the insertion position depth according to different working conditions, and determine the flow rate of the gas in the pipe according to different working conditions;

[0004] Traditional casting degassing methods, such as natural degassing, are simple and easy to implement, but have low degassing efficiency and are difficult to meet the requirements of modern casting processes for the purity of molten metal. Natural degassing usually relies on the inherent characteristics of molten metal, such as the natural rise of bubbles when standing still, or by increasing the temperature of molten metal to accelerate the discharge of bubbles. However, this method is not only time-consuming, but also has limited degassing effect, and it is difficult to completely remove tiny bubbles and impurities in the molten metal. Mechanical degassing methods have gradually received widespread attention. Mechanical degassing methods accelerate the discharge of bubbles and the removal of impurities by introducing external forces such as vibration, stirring, and inert gas injection. However, existing mechanical degassing devices still have certain problems in application. For example, the clamping mechanism is unstable, which makes it easy for the molten metal to overflow or splash during the vibration process; the degassing efficiency is not high, which makes it difficult to meet the requirements of high-quality casting; the impurity treatment is not thorough, and the purity of the molten metal is difficult to reach the ideal level; improper waste gas treatment causes potential harm to the environment and workers;

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] In a typical implementation of this application, please refer to Figures 1 to 11As shown, a hydraulic vibration degassing device for mechanical casting comprises: a bracket 1, a vibration assembly is arranged on the bracket 1, and the vibration assembly comprises: a lower support plate 36, the lower support plate 36 is fixedly mounted on the bracket 1, an upper support plate 37 is arranged above the lower support plate 36, a plurality of vibration springs 38 are arranged between the lower support plate 36 and the upper support plate 37, a plurality of eccentric vibration motors 39 are fixedly mounted on the top surface of the lower support plate 36, a metal liquid storage tank 2 is fixedly mounted on the top surface of the vibration assembly through a clamping member, the clamping member comprises: four second electric push rods 41, the four second electric push rods 41 are respectively arranged on the upper support plate 37, the output shafts of the four second electric push rods 41 are all fixedly mounted with a clamping plate 42, a cross groove 40 is opened on the top surface of the lower support plate 36, the four second electric push rods 41 and the clamping plate 42 are respectively located in the four grooves of the cross groove 40, and a hydraulic adjustment assembly is arranged above the metal liquid storage tank 2, and the hydraulic adjustment assembly comprises: a hydraulic drive generator 3, the hydraulic drive generator 3 is arranged On the bracket 1, a hydraulic cylinder 4 is arranged on the top surface of the bracket 1 located above the metal liquid storage tank 2, and a hydraulic pipe 5 is arranged between the hydraulic drive generator 3 and the hydraulic cylinder 4; a degassing mechanism, the degassing mechanism is arranged on the output end of the hydraulic cylinder 4, and the degassing mechanism includes: a fixed seat 6, the fixed seat 6 is fixedly installed on the bottom surface of the output end of the hydraulic cylinder 4, the bottom surface of the fixed seat 6 is rotatably connected with a stirring blade 7, the bottom surface of the stirring blade 7 is fixedly installed with a pressure sensor 8, the side wall of the fixed seat 6 is installed with a nozzle 11 through an adjustment component, an inert gas storage tank 19 is fixedly installed below the hydraulic drive generator 3, a gas pipeline 20 is arranged on one side of the inert gas storage tank 19, and one side of the gas pipeline 20 is connected to the nozzle 11, a regulating valve 21 is rotatably connected on the side wall of the bracket 1, and a detector 22 is fixedly installed on the top surface of the regulating valve 21, and the degassing component also includes a crushing component and a purification component; a controller 43, the controller 43 is fixedly installed on the top surface of the bracket 1, and is used to control various parts on the equipment;

[0033] According to the above features, the metal liquid storage tank 2 can be clamped, and the metal liquid inside the metal liquid storage tank 2 can be degassed. Specifically, the staff places the metal liquid storage tank 2 on the bottom surface of the upper support plate 37, and turns on the second electric push rod 41 through the controller 43, so that the clamping plate 42 connected to the output shaft of the second electric push rod 41 clamps the outer surface of the metal liquid storage tank 2, and then turns on the eccentric vibration motor 39 through the controller 43, so that the eccentric vibration motor 39 rotates and generates vibration force, so that the upper support plate 37 vibrates through the vibration spring 38. When the upper support plate 37 vibrates, part of the bubbles inside the metal liquid storage tank 2 will move upward. At this time, the output end of the hydraulic cylinder 4 is moved downward through the controller 43, so that the fixed seat 6 fixedly connected to the output end of the hydraulic cylinder 4 moves downward toward the bottom surface inside the metal liquid storage tank 2. At this time, the control The device 43 can rotate the stirring blade 7 to rotate the metal liquid in the metal liquid storage tank 2. When the pressure sensor 8 on the bottom of the stirring blade 7 contacts the bottom of the metal liquid storage tank 2, the output end of the hydraulic cylinder 4 will automatically stop moving down, and at this time, the staff can adjust the adjustment component through the controller 43. When the nozzle 11 is in a position opposite to the metal liquid in the metal liquid storage tank 2, the staff rotates the regulating valve 21 to allow the inert gas in the inert gas storage tank 19 to be ejected from the nozzle 11 through the gas pipeline 20. At this time, the inert gas will collide with the bubbles in the rotating metal liquid to improve its purification effect. In addition, because the nozzle 11 is on the bottom of the metal liquid storage tank 2, when a large amount of inert gas is ejected from the nozzle 11, the bubbles in the metal liquid will rise rapidly, reducing pores and surface defects.

[0034] It is worth mentioning that the working principle of the stirring blade 7 is to drive the stirrer to rotate through the motor to fully mix different materials and achieve a uniform mixing effect. The stirring blade 7 receives electrical energy from the power supply, and the controller 43 sends a start signal to the motor, and the motor starts to rotate. The motor drives the stirring blade 7 to rotate through the transmission device to mix the materials. The controller 43 can control the mixing effect and uniformity of the materials by adjusting the motor speed and stirring time. The working principle of the second electric push rod 41 is to achieve precise positioning and motion control of the push rod by controlling the motor speed and torque, as well as the movement speed and position of the push rod. After the motor is reduced in speed by gears, it drives a pair of lead screw nuts to convert the rotational motion of the motor into the linear motion of the push rod. The controller 43 receives a control signal from an external device or system, such as a switch signal, an analog signal or a digital signal. The controller 43 processes the received signal and determines the speed, torque and running direction of the motor according to the type and value of the signal. The controller 43 converts the processed signal into an instruction that the motor can understand through the drive circuit, and drives the motor to rotate at the specified speed, torque and running direction. The motor drives the lead screw nut after gear reduction to realize the linear motion of the push rod. The controller 43 can realize the precise positioning and motion control of the push rod by adjusting the speed and torque of the motor and the position feedback of the push rod. The eccentric vibration motor 39 receives electric energy from the power supply. The controller 43 sends a start signal to the motor, and the motor starts to rotate. Due to the presence of the eccentric block, centrifugal force is generated when the motor rotates, and the driving device generates vibration. The controller 43 can control the frequency and amplitude of the vibration by adjusting the speed of the motor and the weight or position of the eccentric block. The above working principle and process are mature existing technical means, so they are no longer described in the present invention.

[0035] As a preferred implementation in this embodiment, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 8 As shown, the crushing assembly includes: a baffle 23, which is fixedly mounted on the top surface of the fixed seat 6, a through slot 24 is provided on the side wall of the baffle 23, a support seat 28 is fixedly mounted on the right side wall of the baffle 23, and a plurality of rotating blades 29 are rotatably connected to the right side wall of the support seat 28, and the crushing assembly also includes: a fixed plate 25, which is fixedly mounted on the left side wall of the baffle 23, a filter screen 26 is provided on the left side wall, the front side wall and the rear side wall of the fixed plate 25, the right side wall of the fixed plate 25 is connected to the through slot 24, and a collection box 27 is provided inside the fixed plate 25;

[0036] According to the above characteristics, impurities in the metal liquid in the metal liquid storage tank 2 can be crushed and collected, and bubbles in the metal liquid can be crushed. Specifically, when the stirring blade 7 rotates, the metal liquid inside the metal liquid storage tank 2 will generate a vortex through the rotation of the stirring blade 7. At this time, the flow direction of the metal liquid is consistent. At this time, the metal liquid will push the rotating blade 29 to rotate. When the rotating blade 29 rotates, the impurities in the metal liquid will be crushed and blocked by the filter screen 26. When the baffle 23 rises, it will drive the fixed plate 25 to rise synchronously, so that the impurities on the filter screen 26 fall into the collection box 27 for collection, and when the bubbles in the metal liquid hit the filter screen 26, they will be crushed by the filter screen 26 and the impurities crushed by the rotating blade 29. Moreover, when the vortex rotates, an inward centripetal force will be formed, which is similar to the effect of the earth's gravity pulling an object to the ground. In the vortex, this centripetal force pulls foreign matter such as impurities in the metal liquid to the center of the vortex, that is, below, so that impurities and bubbles pass through the filter screen 26 evenly, so as to improve the use effect of the filter screen 26.

[0037] As a preferred implementation in this embodiment, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Fig. 9 As shown, the purification component includes: a disc 30, which is slidably mounted on the outer surface of the output end of the hydraulic cylinder 4, and the inside of the disc 30 is slidably mounted with an activated carbon plate 31, a negative ion ecological silicon crystal plate 32, a glass fiber reinforced plastic dust removal filter plate 33 and a bottom plate 34 from top to bottom, and the bottom plate 34 prevents the activated carbon plate 31, the negative ion ecological silicon crystal plate 32 and the glass fiber reinforced plastic dust removal filter plate 33 from being separated from the inside of the disc 30, and the top surface of the disc 30 and the bottom surface of the bottom plate 34 are both provided with a plurality of vents 35;

[0038] According to the above-mentioned characteristics, the exhaust gas flowing out from the top of the metal liquid storage tank 2 can be filtered. Specifically, because the disc 30 is slidably installed on the outer surface of the output end of the hydraulic cylinder 4, when the output end of the hydraulic cylinder 4 moves downward, the disc 30 will be in close contact with the top surface of the metal liquid storage tank 2, so that the exhaust gas generated in the metal liquid storage tank 2 passes through the fiberglass dust removal filter plate 33, the negative ion ecological silicon crystal plate 32 and the activated carbon plate 31 in turn, and then is discharged through the vent 35 to reduce the harm to the surrounding staff and reduce the pollution to the environment. When the degassing is completed, when the output end of the hydraulic cylinder 4 rises, the bottom surface of the baffle 23 contacts the bottom plate 34, so that it drives the disc 30 to rise, which is convenient for the staff to move the metal liquid storage tank 2 away after the degassing is completed.

[0039] As a preferred implementation in this embodiment, please refer to Figure 6, Figure 7 and Fig.11 As shown, the adjustment component includes: a sphere 9, which is fixedly mounted on the side wall of the fixed seat 6, and openings are provided on both side walls of the sphere 9. An inner ball 10 is movably mounted inside the sphere 9, and one end of the inner ball 10 away from the fixed seat 6 is fixedly connected to the side wall of the nozzle 11. A cavity 12 is provided on the top surface of the fixed seat 6, and a sealing plate 13 is fixedly mounted on the side wall of the cavity 12. A connecting rod 14 is fixedly mounted on one end of the inner ball 10 located in the cavity 12, and a rotating column 15 is rotatably connected to the side of the connecting rod 14 away from the nozzle 11. The adjustment member also includes a driving member, which includes: a magnetic levitation track 16, which is fixedly mounted inside the cavity 12, and a slide groove is provided on the top surface of the magnetic levitation track 16. A suspension plate 17 is slidably connected in the slide groove of the magnetic levitation track 16, and a first electric push rod 18 is fixedly mounted on the top surface of the suspension plate 17, and the output shaft of the first electric push rod 18 is connected to the side wall of the rotating column 15.

[0040] According to the above features, the direction of the nozzle 11 can be controlled. Specifically, when the nozzle 11 needs to be moved left and right, it is only necessary to energize the magnetic levitation track 16 to move the suspension plate 17, thereby driving the first electric push rod 18 to move synchronously. When the first electric push rod 18 moves, the rotating column 15 connected to the output shaft of the first electric push rod 18 drives the connecting rod 14 to move, so that the inner ball 10 moves inside the sphere 9, and the nozzle 11 moves synchronously. When the nozzle 11 moves up and down when necessary, it is only necessary to turn on the first electric push rod 18 to extend and retract its output shaft, thereby driving the rotating column 15 and the connecting rod 14 to rise and fall. It is worth mentioning that the magnetic levitation controls the electromagnetic force between the magnetic levitation track 16 and the suspension plate 17 by changing the direction and size of the current, so that the suspension plate 17 is suspended on the track. Specifically, when the magnets on the magnetic levitation track 16 are energized, a suspension magnetic field is formed, and the repulsion or attraction of the magnets is used to suspend the suspension board 17 in the slide groove of the magnetic levitation track 16. At the same time, the coils of the magnetic levitation track 16 and the suspension board 17 are energized in sequence to form a traveling wave magnetic field, thereby driving the suspension board 17 to continue to move forward. The driving method of the above-mentioned magnetic levitation track 16 and the suspension board 17 can also be replaced with an electric drive threaded rod to move the suspension board 17. Specifically, the threaded rod is rotatably connected to the internal slide groove of the magnetic levitation track 16, and the suspension board 17 is threadedly connected to the threaded rod. A drive motor is fixedly installed on one side of the magnetic levitation track 16, and the output shaft of the drive motor is connected to one end of the threaded rod. When the drive motor rotates, the threaded rod can drive the suspension board 17 to move.

[0041] Working principle:

[0042] When in use, the staff places the metal liquid storage tank 2 on the upper support plate 37, drives the clamping plate 42 to clamp the tank body through the second electric push rod 41, turns on the eccentric vibration motor 39, and vibrates the upper support plate 37 and the metal liquid storage tank 2 through the vibration force, so that the bubbles in the tank move upward, and the hydraulic cylinder 4 pushes the fixing seat 6 to move downward, so that the stirring blade 7 is immersed in the metal liquid and rotates to form a vortex, and the bubbles are broken at the same time. When the pressure sensor 8 detects that the stirring blade 7 contacts the bottom of the tank, the hydraulic cylinder 4 stops moving downward, adjusts the nozzle 11 to a suitable position, and opens the regulating valve 21 to make the inert gas spray out from the nozzle 11 and collide with the bubbles in the rotating metal liquid to improve the purification effect. The rotation of the stirring blade 7 drives the rotating blade 29 to rotate. Impurities in the metal liquid are broken and blocked by the filter 26. When the baffle 23 rises, it drives the fixed plate 25 and the filter 26 to rise, so that the impurities fall into the collection box 27. The disc 30 is in close contact with the top surface of the metal liquid storage tank 2. The exhaust gas generated in the tank is filtered through the fiberglass dust removal filter plate 33, the negative ion ecological silicon crystal plate 32 and the activated carbon plate 31, and finally discharged through the vent 35. The magnetic suspension track 16 is combined with the suspension plate 17. The electromagnetic force is controlled by changing the direction and size of the current to move the suspension plate 17 on the track. The movement of the suspension plate 17 drives the first electric push rod 18 and the nozzle 11 to move, so as to realize the left and right movement of the nozzle 11. The extension and retraction of the first electric push rod 18 controls the up and down movement of the nozzle 11.

[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
