Description

Technical Field

[0001] This invention relates to the field of demagnetizing table technology, and in particular to a demagnetizing table for a weighing, marking, atomizing, and oiling production line. Background Technology

[0002] Demagnetization is a technique used to eliminate or weaken the magnetism of objects. Magnetic objects contain numerous magnetic domains. When unmagnetized, these domains are randomly arranged, and the object as a whole exhibits no magnetism. However, when an object is magnetized, the domains align regularly in a certain direction, giving the object its magnetic properties. Demagnetization disrupts this ordered arrangement of domains, causing them to return to a disordered state, thereby weakening or even eliminating the object's magnetism. Demagnetization can eliminate magnetic interference, improve processing accuracy, ensure the normal operation of equipment, and even improve material properties.

[0003] In principle, demagnetizing equipment typically uses methods such as thermal demagnetization, alternating magnetic field demagnetization, and reverse demagnetization to eliminate the magnetism of objects. This technology is widely used in various fields.

[0004] In existing inventions, when demagnetizing complex products, the complex shape and uneven distribution of the internal magnetic field may lead to a large amount of residual magnetism. Furthermore, existing demagnetizing devices are not convenient for making the workpiece vibrate up and down, left and right, and rotate synchronously during the demagnetization operation. Based on the principles of vibration and oscillation demagnetization and the principle of cyclic switching of the demagnetization direction of alternating magnetic field, we propose a demagnetizing table for a weighing, marking, atomizing, and coating production line.

[0030] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0031] like Figures 1-9 The demagnetizing table shown is used in a weighing, marking, atomizing, and oiling production line. It includes a frame 1, with two symmetrically arranged first demagnetizers 7 and an atomizing oil spraying assembly installed on the top surface of the frame 1. A second demagnetizer 8 and an air blowing assembly are installed on the frame 1.

[0032] The first demagnetizer 7 and the second demagnetizer 8 generate a weak magnetic field opposite to the original magnetic field through the principle of electromagnetic induction. This weak magnetic field cancels out the original magnetic field of the magnetic material, causing the magnetic field lines to become disordered, thereby weakening the magnetic field.

[0033] It also includes a drive module, on which a rotatable workstation frame 2 is connected for transmission. A rotatable transmission bevel gear ring 3 is rotatably sleeved on the workstation frame 2. A passive rotating ring 4 that can move up and down is sleeved on the workstation frame 2. A set of demagnetizing seats 5 arranged in a circular array is slidably connected to the workstation frame 2. Each demagnetizing seat 5 and the passive rotating ring 4 are hinged together with a connecting arm 6.

[0034] The drive module includes an inner moving frame 14 and a motor 15 fixedly mounted on the frame 1. The inner moving frame 14 is rotatably connected to the passive rotating ring 4 through a bearing. The inner moving frame 14 is sleeved on the station rotating frame 2. The bottom surface of the inner moving frame 14 is respectively equipped with a guide column and a guide tooth plate 16. The guide column is slidably connected to the frame 1. The output shaft end of the motor 15 and the station rotating frame 2 are both equipped with first bevel gears. The two first bevel gears mesh with each other. The output shaft end of the motor 15 is fixedly equipped with a half-face gear 17. The half-face gear 17 is connected to the guide tooth plate 16 for transmission. The top surface of the inner moving frame 14 is equipped with a return spring 18 that is limited by the station rotating frame 2.

[0035] When the workpiece 11 to be demagnetized is demagnetized, the motor 15 outputs a speed in a set state. After the motor 15 outputs the speed, it drives the stationary rotating frame 2 to rotate at a set speed. After the motor 15 outputs the speed, through the setting of the half-face gear 17, the guide tooth plate 16 and the return spring 18, the inner moving frame 14 can move up and down at a set speed during the rotation of the stationary rotating frame 2. After the inner moving frame 14 moves up and down to reset, it drives the passive rotating ring 4 to move up and down to reset within a set stroke. Through the up and down reset of the passive rotating ring 4, the demagnetizing seat 5 can move left and right to reset. Through the left and right reset of the demagnetizing seat 5, the workpiece 11 to be demagnetized will vibrate horizontally at a set speed.

[0036] Each demagnetizing base 5 is equipped with a demagnetizing component;

[0037] The demagnetizing component includes a frequency table 9 that can vibrate up and down. A frequency generation module is provided between the frequency table 9 and the demagnetizing base 5. A rotatable clamping shaft 10 is provided on the frequency table 9, and the workpiece 11 to be demagnetized is clamped on the clamping shaft 10.

[0038] The vibration frequency generation module includes a horizontal shaft 26 rotatably connected to the workstation frame 2, a hollow shaft 27 rotatably connected to the demagnetizing seat 5, a vertical shaft 28 and a convex shaft 29. The hollow shaft 27, the clamping shaft 10, the convex shaft 29 and the vertical shaft 28 are all driven by the horizontal shaft 26.

[0039] The tail end of the horizontal shaft 26 is provided with a tail bevel tooth, which is connected to the transmission bevel tooth ring 3 for transmission.

[0040] The hollow shaft 27 has a hollow groove with openings at both ends and slidably connected to the horizontal shaft 26. The cross-sections of the hollow groove and the horizontal shaft 26 are both regular polygons.

[0041] The axes of the hollow groove and the horizontal shaft 26 are both perpendicular to the rotation axis of the station frame 2;

[0042] By setting the hollow slot and the regular polygonal cross section of the horizontal axis 26, the horizontal axis 26 can continuously drive the hollow axis 27 on the demagnetizing seat 5 when the demagnetizing seat 5 moves back and forth.

[0043] A second bevel gear is installed on both the hollow shaft 27 and the vertical shaft 28, and the two second bevel gears mesh with each other.

[0044] A synchronous belt is used for transmission between the convex shaft 29 and the hollow shaft 27. The clamping shaft 10 has a bottom groove with an opening at the bottom end that is slidably connected to the vertical shaft 28. The cross-sections of the bottom groove and the vertical shaft 28 are both regular polygons.

[0045] The axes of the vertical shaft 28 and the clamping shaft 10 are parallel to the rotation axis of the station rotating frame 2. The vertical shaft 28 is set through the regular polygonal cross-section of the bottom groove and the vertical shaft 28, so that when the frequency table 9 drives the clamping shaft 10 to move up and down, the vertical shaft 28 and the clamping shaft 10 can rotate continuously. Through the rotation of the clamping shaft 10, the workpiece 11 to be demagnetized will rotate at a set speed during the demagnetization operation. Through the rotation of the workpiece 11 to be demagnetized during the demagnetization operation, the alternating magnetic field acting on the workpiece 11 can repeatedly change the intensity of the alternating magnetic field acting on the workpiece 11 to be demagnetized and the magnetization direction of the workpiece 11 to be demagnetized, thereby improving the demagnetization efficiency and demagnetization effect of the workpiece 11 to be demagnetized.

[0046] A polarizing plate 30 is mounted on the convex shaft 29, and a vibrating wheel 31 is rotatably mounted on the frequency table 9. The vibrating wheel 31 is in contact with the polarizing plate 30, and a vibration spring 32 that is limited by the station rotating frame 2 is mounted on the top surface of the frequency table 9.

[0047] During the demagnetization operation, the motor 15 outputs a rotational speed. After the motor 15 outputs a rotational speed, the frequency table 9 vibrates at a high frequency through the setting of the polarizing plate 30, the vibrating wheel 31 and the vibration spring 32. Through the high-frequency vibration of the frequency table 9, the workpiece 11 to be demagnetized can vibrate up and down at a set frequency during demagnetization.

[0048] During the demagnetization process of the workpiece 11 to be demagnetized, the synchronous up-and-down vibration, left-and-right vibration and rotation can, on the one hand, use the principle of vibration and oscillation to destroy the magnetic domain arrangement on the workpiece 11 to be demagnetized, thereby weakening and eliminating the magnetism; on the other hand, it can cyclically change the demagnetization direction of the alternating magnetic field on the workpiece 11 to be demagnetized, thereby effectively improving the demagnetization efficiency and demagnetization effect of the workpiece 11 to be demagnetized.

[0049] The clamping shaft 10 is equipped with an air clamping module that communicates with the air blowing assembly. An oil receiving hopper 12 is fixedly installed on the frequency table 9. An oil drain valve is installed at the bottom of the oil receiving hopper 12. An electromagnetic coil 13 is installed on the oil receiving hopper 12. It also includes a conductive ring 35 that is rotatably sleeved on the ventilation column 20. The electromagnetic coil 13 is powered through the conductive ring 35.

[0050] The oil collection hopper 12 is designed to collect excess oil during the spraying process.

[0051] The air-blowing assembly includes an air pump 19 and an air column 20 mounted on a frame 1. A rotating workstation frame 2 is rotatably mounted on the air column 20. An internal air passage 21 is fixedly opened inside the air column 20. The air outlet of the air pump 19 is connected to the internal air passage 21. A pressure probe is provided at the connection between the air pump 19 and the internal air passage 21. A microcontroller 22 is mounted on the frame 1. The data terminal of the pressure probe is connected to the microcontroller 22. An air distribution ring 23 is rotatably mounted on the air column 20. The inner cavity of the air distribution ring 23 is connected to the internal air passage 21.

[0052] The air clamp module includes an external air passage 24 opened inside the clamping shaft 10, an air distribution ring 23 rotatably connected to the external air passage 24 through a corrugated duct, an annular groove opened on the clamping shaft 10, an annular clamping bag 25 installed on the annular groove, and the inner cavity of the annular clamping bag 25 connected to the external air passage 24.

[0053] By setting up the air blowing assembly and the air clamp module, the workpiece 11 to be demagnetized is effectively fixed on the clamping shaft 10;

[0054] The atomizing oil spraying assembly includes an oil tank 33 mounted on a stand 1 and a spray pipe 34 mounted on the stand 1. A spray pump is mounted on the top surface of the oil tank 33. The oil inlet of the spray pump is connected to the oil tank 33, and the oil outlet of the spray pump is connected to the spray pipe 34.

[0055] During the demagnetization process, the atomizing oil spraying component continuously atomizes and sprays oil. The oil can block and buffer the magnetism of magnetic products. Applying oil to the outer wall of the workpiece 11 to be demagnetized can, to a certain extent, block the influence of external magnetic fields on the magnetic domains inside the workpiece 11. It also buffers the magnetic field generated by the interaction between the magnetic domains inside the workpiece 11. In addition to demagnetizing, the oil film formed on the surface of the workpiece 11 can isolate air and moisture, thus preventing rust.

[0056] The spray pipe 34 and the two first demagnetizers 7 are both located above the clamping shaft 10. The arrangement direction of the two first demagnetizers 7 is perpendicular to the axis of the clamping shaft 10, and the arrangement direction of the second demagnetizer 8 is perpendicular to the axis of the clamping shaft 10.

[0057] It also includes a straight shaft 36 rotatably connected to the ventilation column 20, an intermediate bevel gear mounted on the straight shaft 36, a lateral bevel gear mounted on the station frame 2 and the transmission bevel gear ring 3, both lateral bevel gears being connected to the intermediate bevel gear, and the intermediate bevel gear being positioned between the two lateral bevel gears.

[0058] The working principle of this invention is as follows: Before demagnetization, the workpiece 11 to be demagnetized is connected to the weighing, marking, atomizing and oiling production line.

[0059] The weighing, marking, atomizing, and oiling production line is used for weighing, marking, and primary atomizing oil removal of workpieces 11 to be demagnetized.

[0060] Before demagnetization, multiple workpieces 11 to be demagnetized are clamped onto various clamping shafts 10. After the workpieces 11 are clamped, multiple electromagnetic coils 13 operate synchronously, heating the workpieces 11 to the Curie temperature. Once the workpieces 11 are heated to the Curie temperature, thermal demagnetization of the workpieces 11 is achieved. After thermal demagnetization, the electromagnetic coils 13 stop operating, and the workpieces 11 are then gradually cooled. After the workpieces 11 have cooled completely, the motor 15 outputs a rotational speed, which in turn drives the stationary rotating frame 2 to rotate at a predetermined speed. Furthermore, after the motor 15 outputs its rotational speed, the inner moving frame 14 can move up and down at a set speed during the rotation of the stationary rotating frame 2, thanks to the arrangement of the half-face gear 17, the guide gear plate 16, and the return spring 18. When the inner moving frame 14 moves up and down to return to its original position, it then drives the passive rotating ring 4 to move up and down to return to its original position within a set stroke. The up and down movement of the passive rotating ring 4 causes the demagnetizing seat 5 to move left and right to return to its original position. The left and right movement of the demagnetizing seat 5 causes the workpiece 11 to vibrate horizontally at a set speed. After the motor 15 outputs its rotational speed... By configuring the polarizing plate 30, vibrating wheel 31, and vibrating spring 32, the frequency table 9 vibrates at a high frequency. This high-frequency vibration of the frequency table 9 causes the workpiece 11 to vibrate up and down at a set frequency during demagnetization. The simultaneous up-and-down, left-and-right, and rotating vibrations of the workpiece 11 during demagnetization effectively disrupt the magnetic domain arrangement on the workpiece 11, thereby weakening and eliminating magnetism. Furthermore, the alternating magnetic field can be cyclically changed to alter the demagnetization direction of the workpiece 11, thus improving the overall performance of the workpiece. The demagnetizing efficiency and effect of the demagnetized workpiece 11: During the demagnetizing operation, the atomizing oil spraying component continuously atomizes and sprays oil. The oil can block and buffer the magnetism of magnetic products. Applying oil to the outer wall of the workpiece 11 to a certain extent blocks the influence of external magnetic fields on the magnetic domains inside the workpiece 11, and also buffers the magnetic field influence generated by the interaction between the magnetic domains inside the workpiece 11. In addition to demagnetizing, the oil film formed on the surface of the workpiece 11 can isolate air and moisture, so that the workpiece 11 can prevent rust.
