Description

Technical Field

[0001] The utility model belongs to the technical field of magnetizers, and in particular relates to a magnetizer for magnetic steel sheets which is convenient for positioning. Background Art

[0002] Magnetic steel sheet is a kind of alloy steel with strong magnetism, which is usually used in technological products such as motors. The magnetic steel sheet needs to be magnetized to have magnetism. It is usually magnetized by a magnetizer. The capacitor is first charged with a DC high voltage, and then discharged through a coil with extremely small resistance. The peak value of the discharge pulse current can reach tens of thousands of amperes. This current pulse generates a strong magnetic field in the coil. The magnetic steel sheet is placed in the magnetizing cylinder in the magnetizer. The magnetic field magnetizes the magnetic steel sheet placed in the coil for magnetization.

[0003] Chinese patent application No. 202121825824.4 discloses an automatic magnetizing device with a positioning function. The patent sets a first suction device and a second suction device. The first suction device and the second suction device adopt a vacuum suction principle, and utilizes the two suction devices to fit the magnet, and then extracts the air between the suction device and the magnet, so that the magnet and the suction device fit tightly together, so that the magnet can be lifted, which is convenient and fast, and not easy to fall, thereby effectively avoiding damage caused by accidental falling from a high altitude. However, in use, the two suction devices are driven by a motor and two cylinders to move left and right. The magnetic steel sheet placed in the magnetizing cylinder is automatically taken and placed, so as to realize automatic feeding and taking of the magnetic steel sheet when magnetizing. The motor and the cylinder will generate certain vibrations during operation, and the vibrations will be transmitted to the magnetizing cylinder in the magnetizer, causing the magnetic steel sheet in the magnetizing cylinder to move due to the vibration, resulting in misalignment between the suction device and the magnetic steel sheet in the magnetizing cylinder when the subsequent suction device takes the material, so that the area of ​​the suction device contacting the magnetic steel sheet is reduced or even no contact is made, resulting in the magnetic steel sheet placed in the magnetizing cylinder being unstable or falling when taking the material, thereby reducing the use effect of the magnetizer. For this reason, we propose a magnetic steel sheet magnetizer that is easy to position. Utility Model Content

Two groups of nut seats 207 are arranged on the outside of the opposing screw rod 200. The nut seats 207 can convert the rotary motion of the opposing screw rod 200 into linear motion during operation. The outer wall of the nut seat 207 is installed with a connecting plate 201, and vertical plates 204 are installed on the opposite sides of the ends of the two groups of connecting plates 201. Clamps 206 are installed at the bottom of the vertical plates 204, and rubber buffer plates 211 are installed on the opposite sides of the two groups of clamps 206. When in use, the rubber buffer plates 211 will contact the side of the magnetic steel sheet body 105, which can play a buffering effect and avoid the formation of clamping marks on the side of the magnetic steel sheet body 105. The side of the vertical plate 202 is provided with a driving member for rotating the opposing screw rod 200.

[0024] Example 2

[0025] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The driving member includes a side plate 205, which is fixed to the side of the vertical plate 202.

[0028] Example 3

[0029] Based on Example 2, see Figure 6 As shown, cleaning components for cleaning the opposing screw rod 200 are installed on both sides of the nut seat 207. The cleaning components include two sets of arc plates 300. Concave plates 301 are fixedly installed on the sides of the arc plates 300. Arc brushes 302 are provided at the ends of the concave plates 301. The arc brushes 302 can clean hard dust or impurities attached to the outside of the opposing screw rod 200.

[0030] The concave plate 301 and the arc brush 302 are fixedly connected by two sets of screws. During use, the arc brush 302 that is worn out after a long period of use can be replaced by disassembling and assembling the screws. The screws are unscrewed and the arc brush 302 is removed. A new arc brush 302 is taken out and replaced by following the reverse principle mentioned above. The cleaning effect of the arc brush 302 on the opposing screw rod 200 is increased, and the inner wall of the arc plate 300 is fixedly connected to the outer wall of the nut seat 207.

[0031] The cleaning component designed in the utility model can be used to clean some hard dust or impurities attached to the outer wall of the opposing screw rod 200 when the nut seat 207 moves left and right on the opposing screw rod 200, thereby reducing the degree of wear on the inner wall of the moving nut seat 207 caused by the hard dust or impurities attached to the outer wall of the opposing screw rod 200, thereby facilitating use.

[0033] The working principle and use process of this utility model:

[0034] When the utility model is in use, after the unmagnetized magnetic steel sheet body 105 is sucked and placed into the magnetizing cylinder 101 by the suction device, the driving motor is started, and the driving motor drives the opposing screw rod 200 to rotate. At this time, the two groups of nut seats 207 outside the opposing screw rod 200 move in opposite directions, driving the connecting plate 201 to move, and at the same time, the connecting plate 201 drives the vertical plate 204 to move, and at the same time, the vertical plate 204 drives the rubber buffer plate 211 to move, and then the rubber buffer plate 211 contacts and clamps the magnetic steel sheet body 105 located in the magnetizing cylinder 101, and positions the magnetic steel sheet body 105. Then the suction device is separated from the magnetic steel sheet body 105, and the device is turned on to magnetize the magnetic steel sheet body 105. After the magnetization is completed, according to the above-mentioned opposite principle, the two groups of rubber buffer plates 211 move in opposite directions and separate from the surface of the magnetic steel sheet body 105, and finally the magnetized magnetic steel sheet body 105 is sucked and lifted by the suction device for material collection;

[0035] When the nut seat 207 moves left and right on the opposing screw rod 200, it will drive the arc brush 302 to move. At this time, the moving arc brush 302 will clean some hard dust or impurities attached to the outer wall of the opposing screw rod 200, thereby reducing the wear of the inner wall of the nut seat 207 caused by some hard dust or impurities attached to the outer wall of the opposing screw rod 200 when the nut seat 207 moves.
