Abstract

The present application relates to the field of laser cutting processing, especially to a magnetic material cutting device with protection function. The magnetic material cutting device with protection function, in the laser cutting work, the outer surface of the magnetic monomer is wrapped by the downward spraying of the cooling gas flow through the protection air pipe, so as to avoid the continuous erosion of the high temperature heat to the magnetic monomer. After completing the laser cutting work of each column of magnetic monomers, the electric elevator controls the fixed rod to cooperate with the diamagnetic plate to separate the magnetic monomers on each center steel column from the magnetic base plate and transfer them to the guide inclined frame, so that the whole column of magnetic monomers timely leave the working area of the laser cutting machine along the guide inclined frame, avoiding the laser cutting machine from splashing a large amount of high temperature sparks to the magnetic monomers during the laser cutting work in the adjacent position. The technical problem that the magnetic monomers cut from the magnetic base plate fall into the collection net below and are affected by the high temperature sparks for a long time to affect the magnetic effect is solved.

Description

Technical Field

[0001] This invention relates to the field of laser cutting, and more particularly to a magnetic material cutting device with protective functions. Background Technology

[0002] On a laser cutting production line for magnetic materials, magnetic monomers cut from a magnetic substrate fall into a collection net below by gravity. However, the high-temperature sparks generated by the laser beam in the cutting zone are ejected downwards with the airflow, directly impacting the magnetic debris on the collection net. A large number of high-temperature sparks accumulate on the magnetic monomers, forming a thermal shock zone on the surface of the monomers. This generates severe thermal stress and rapid cooling, causing microstructural distortion of the grains, which weakens the material's magnetic permeability and increases iron loss. Furthermore, the prolonged high-temperature environment causes the surface of the magnetic metal to gradually oxidize, forming an oxide layer or slag. These non-magnetic deposits not only reduce the remanent magnetic induction of the magnetic material but also introduce non-uniform magnetic resistance in subsequent assembly or magnetic circuit design, affecting the performance of motors or transformers. Summary of the Invention

[0003] To overcome the drawback that magnetic monomers cut from the magnetic substrate fall into the collection net below and are affected by prolonged exposure to high-temperature spark radiation, thus affecting their magnetic properties, this invention provides a magnetic material cutting device with protective functions.

[0004] The technical implementation scheme of the present invention is as follows: a magnetic material cutting device with protective function, comprising a control machine tool, a laser cutting machine, a protective air pipe, a mounting frame, a waste collection box, an electric lift, a fixing rod, a torsion spring, a support frame, a central steel column, an antimagnetic plate, a guide frame, and a limiting bracket; the control machine tool is equipped with a laser cutting machine for laser cutting magnetic units on a magnetic substrate; a protective air pipe is fixedly connected to the upper part of the laser cutting machine; a mounting frame is fixedly connected inside the control machine tool; a positioning frame for placing the magnetic substrate is fixedly connected to the mounting frame; a waste collection box is fixedly connected inside the mounting frame; the waste collection box... The system is equipped with several electric lifts; the lifting components of the electric lifts are rotatably connected to fixed rods; torsion springs are fixedly connected between the fixed rods and the corresponding lifting components of the electric lifts; several support frames are fixedly connected to the fixed rods; a central steel column is fixedly connected to the support frames; an antimagnetic plate is slidably connected to the central steel column; guide frames corresponding to the fixed rods are installed on the mounting frame, the guide frames are located below the corresponding fixed rods, the middle part of the guide frames is designed with a hollow structure, and the width of the hollow structure in the middle of the guide frames is greater than the width of the antimagnetic plate; two left and right limit brackets are fixedly connected to the hollow structure of the guide frames.

[0005] As a further preferred option, a tension spring is fixed between the antimagnetic plate and the corresponding support frame.

[0006] As a further preferred option, a suction tube is fixedly connected to the mounting bracket; the fixing rod is a hollow tube structure with closed ends; a telescopic tube connects the fixing rod and the suction tube; and the support frame has a suction hole structure for connecting the corresponding fixing rod.

[0007] As a further preferred option, the antimagnetic plate has a through-hole structure.

[0010] As a further preferred option, the pressure bar is fixed with a buffer pad.

[0011] As a further preferred option, a vibration motor that provides vibration and impact is mounted on the fixed plate.

[0012] As a further preferred option, one side of the waste collection box is connected to an inlet pipe; the other side of the waste collection box is connected to an outlet pipe.

[0013] As a further preferred option, a splash guard is fixed inside the waste collection box.

[0014] This invention has the following advantages: The magnetic material cutting device of this invention, with protective function, allows the laser cutting machine to sequentially cut magnetic monomers on a magnetic substrate. A cooling airflow is sprayed downwards through protective air pipes to envelop the outer surface of the magnetic monomers, preventing continuous erosion of the monomers by high-temperature heat. The cut magnetic monomers are magnetically attracted to corresponding central steel columns below. After each row of magnetic monomers is laser-cut, an electric lifting mechanism, in conjunction with an antimagnetic plate, detaches the magnetic monomers from the magnetic substrate and transfers them to a guide frame. This ensures that the entire row of magnetic monomers leaves the working area of ​​the laser cutting machine promptly, preventing the laser cutting machine from sputtering large amounts of high-temperature sparks onto the magnetic monomers during laser cutting operations at adjacent locations. This solves the technical problem of magnetic monomers cut from the magnetic substrate falling into the collection net below and being subjected to prolonged high-temperature spark radiation, thus affecting their magnetic properties.

[0025] Example 1: A magnetic material cutting device with protective function, such as... Figures 1-8As shown, the system includes a control machine tool 1, a laser cutter 11, a protective air pipe 12, a mounting frame 21, a waste collection box 22, an electric lift 31, a fixing rod 32, a torsion spring 33, a support frame 34, a central steel column 35, an antimagnetic plate 36, a guide frame 41, and a limit bracket 42. The control machine tool 1 is equipped with a laser cutter 11, which performs laser cutting on the magnetic units 51 on the magnetic substrate 5 column by column according to a set program. A protective air pipe 12 is fixedly connected to the upper part of the laser cutter 11, and a cooling airflow conveying device is connected to the outside of the protective air pipe 12. A mounting frame 21 is fixedly connected inside the control machine tool 1. A positioning frame 211 is fixedly connected to the mounting frame 21. A waste collection box 22 is fixedly connected inside the mounting frame 21. Several electric lifts 31 are equidistantly installed in the waste collection box 22 along the left and right directions. The lifting components of each electric lift 31 are rotatably connected to a rotating shaft. A fixed rod 32; a torsion spring 33 is fixedly connected between each fixed rod 32 and the lifting component of the corresponding electric lift 31; several support frames 34 are fixedly connected at equal intervals along the front-back direction on each fixed rod 32; a central steel column 35 is fixedly connected to each support frame 34; an antimagnetic plate 36 is slidably connected to each central steel column 35; guide inclined frames 41 corresponding to the number and position of the fixed rods 32 are installed on the mounting frame 21. The guide inclined frames 41 are designed to be inclined forward and downward. The guide inclined frames 41 are located below the corresponding fixed rods 32. The middle part of the guide inclined frames 41 is designed to be hollow, and the width of the hollow structure in the middle part of the guide inclined frames 41 is greater than the width of the antimagnetic plate 36; a limiting bracket 42 is fixedly connected to the left and right sides of the hollow structure of each guide inclined frame 41; the front side of all guide inclined frames 41 is connected to the same transmission device.

[0026] like Figure 4 , Figure 7 and Figure 8 As shown, each antimagnetic plate 36 is fixedly connected to a tension spring 37 for downward reset between it and the corresponding support frame 34; a suction tube 39 is fixedly connected to the mounting bracket 21, and a suction device is connected to the suction tube 39; each fixing rod 32 is a hollow tube structure with closed ends; a telescopic tube 391 is connected between each fixing rod 32 and the suction tube 39; each support frame 34 has several suction holes 3401 that connect to the corresponding fixing rod 32; each antimagnetic plate 36 has several through holes 3601 that are aligned with the suction holes 3401 of the corresponding support frame 34; a retaining ring 38 is fixedly connected to the bottom of each antimagnetic plate 36, and the retaining ring 38 initially blocks the outside of the corresponding support frame 34, so that the external airflow needs to flow through the through holes 3601 of the antimagnetic plate 36 to enter the suction holes 3401 of the support frame 34.

[0027] The laser cutting operation steps of a magnetic material cutting device with protective function are as follows.

[0028] First, the staff places the magnetic substrate 5 to be cut on the mounting frame 21. Each magnetic unit 51 on the magnetic substrate 5 is magnetically attracted to a corresponding central steel column 35 below it. Then, the laser cutting machine 11 performs laser cutting on each column of magnetic units 51 on the magnetic substrate 5 according to the set program. While the laser cutting machine 11 is cutting each magnetic unit 51, the external cooling airflow delivery device sprays cooling air downwards through the protective air pipe 12. The cooling airflow flows downwards along the surface of the magnetic unit 51. The suction device uses suction pipe 39 and telescopic pipe 391 to perform airflow suction on suction hole 3401 of support frame 34. The cooling airflow flowing downward along the surface of magnetic unit 51 flows through the through hole 3601 of antimagnetic plate 36, suction hole 3401 of support frame 34 and telescopic pipe 391 and is sucked away by suction pipe 39. The cooling airflow wraps the upper and lower surfaces of magnetic unit 51, isolates the excess heat radiation generated by laser cutting machine 11 during operation, and prevents magnetic unit 51 from being corroded by high temperature heat for a long time and affecting its magnetism.

[0029] After the laser cutting machine 11 completes the laser cutting of a whole row of magnetic units 51 along the front-to-back direction on the magnetic substrate 5, these cut magnetic units 51 remain magnetically attracted to the corresponding central steel column 35. Then, the electric lifting machine 31 corresponding to the row of central steel columns 35 drives the fixed rod 32 to move downward. The fixed rod 32 drives all the magnetic units 51 magnetically attracted to the central steel columns 35 to move downward and detach from the magnetic substrate 5. When the first magnetic unit 51 located on the rear side contacts the inclined guide frame 41, the magnetic unit 51 is blocked by the guide frame 41 and drives the fixed rod 32 to rotate clockwise at the left viewing angle. The fixed rod 32 drives the torsion spring 33 to twist, so that all the magnetic units 51 on the fixed rod 32 rotate to be in close contact with the inclined guide frame 41. At this time, all the antimagnetic plates 36 on the fixed rod 32 are in close contact with the two corresponding limit brackets 42. Then the electric lifting machine 31 moves downward. The lowering machine 31 continues to drive the fixed rod 32 and the corresponding central steel column 35 to move downwards. The magnetic unit 51 is blocked by the guide bracket 41 and detaches from the corresponding central steel column 35. At the same time, the antimagnetic plate 36 is blocked by the limiting bracket 42 and moves upwards along the corresponding central steel column 35. Simultaneously, the antimagnetic plate 36 drives the tension spring 37 to stretch upwards, making the antimagnetic plate 36 higher than the central steel column 35, and the central steel column 35 moves downwards away from the magnetic unit 51, causing the magnetic attraction between the magnetic unit 51 and the central steel column 35 to weaken significantly until the magnetic unit 51 slides forward along the guide bracket 41 under its own gravity and falls onto the external transmission equipment, leaving the working area of ​​the laser cutting machine 11. The external transmission equipment then transmits the cut magnetic unit 51 to the next processing equipment. After that, the laser cutting machine 11 performs laser cutting on a row of magnetic units 51 on the magnetic substrate 5 according to the above steps.

[0030] Example 2, based on Example 1 above, as follows: Figures 1-8 As shown, in this embodiment, a lifting frame 13 is slidably connected to the left side of the laser cutting machine 11; an electric push rod 14 is installed on the laser cutting machine 11; the telescopic end of the electric push rod 14 is fixedly connected to the lifting frame 13; a fixed plate 15 is fixedly connected to the lifting frame 13; several pressure rods 16 are fixedly connected to the fixed plate 15; a buffer pad 17 is fixedly connected to the lower end of each pressure rod 16; a vibration motor 18 providing vibration impact is installed on the fixed plate 15; when the laser cutting machine 11 is performing laser cutting on the magnetic unit 51 on the magnetic substrate 5, in order to avoid the laser beam staying in the same area of ​​the magnetic unit 51 for a long time and causing heat accumulation, the laser cutting machine 11 moves at a relatively fast speed. Therefore, there is a weak connection structure between some of the cut magnetic units 51 and the magnetic substrate 5 that is not completely severed, resulting in a weak connection structure between the cut magnetic units 51 and the magnetic substrate 5, which leads to the loss of the entire row of magnetic units. When the body 51 is being unloaded and detached, the magnetic unit 51 cannot smoothly detach from the magnetic substrate 5 along with the central steel column 35. At this time, the electric push rod 14 pulls the lifting frame 13 to move the fixed plate 15 downward. The fixed plate 15 drives all the pressure rods 16 to press down against the surface of the corresponding magnetic unit 51 through the buffer pad 17. The electric push rod 14 pulls the lifting frame 13 to apply downward squeezing force to the magnetic unit 51. At the same time, the vibration motor 18 applies vibration impact to the pressure rods 16 on the fixed plate 15. The pressure rods 16 transmit the vibration impact to the corresponding magnetic unit 51 through the buffer pad 17, causing the weak connection structure between the magnetic unit 51 and the magnetic substrate 5 to be broken. This allows the magnetic unit 51 to detach from the magnetic substrate 5 in time along with the central steel column 35, preventing the magnetic unit 51 from remaining on the magnetic substrate 5.

[0031] Example 3, based on Example 1 above, as follows: Figures 1-8 As shown, in this embodiment, one side of the waste collection tank 22 is connected to an inlet pipe 23, which is connected to a water supply device; the other side of the waste collection tank 22 is connected to an outlet pipe 24, which is connected to a waste liquid filtration device; the external water supply device continuously supplies water into the waste collection tank 22 through the inlet pipe 23, and excess water in the waste collection tank 22 is discharged into the external waste liquid filtration device through the outlet pipe 24, so that water flows continuously in the waste collection tank 22. When the laser cutting machine 11 is performing laser cutting on the magnetic unit 51 on the magnetic substrate 5, the high-temperature sparks sprayed downwards... When the high-temperature airflow comes into contact with the water flowing inside the waste collection box 22, the water flow will carry away most of the high-temperature sparks and high-temperature airflow, preventing the accumulation of high-temperature heat inside the waste collection box 22, and preventing the high-temperature sparks from colliding with the inner wall of the waste collection box 22 and splashing outwards irregularly. A splash guard 25 is fixed inside the waste collection box 22. The installation height of the splash guard 25 is higher than the height of the water surface. After the high-temperature sparks sprayed downward come into contact with the water flow, they cool and become impurity particles. At this time, some impurity particles splash upward from the liquid surface. The splash guard 25 can intercept most of the upward splashing impurity particles.
