Description

Technical Field

[0001] This invention relates to the field of manganese-zinc soft magnetic ferrite processing, and more particularly to a device for grinding the edges of bent magnetic strips. Background Technology

[0002] In the production process of manganese-zinc soft magnetic ferrite, it is necessary to first form a blank. Specifically, a mold is installed on a press, and powder is filled into the mold to form a blank with a certain strength. Among them, the curved magnetic strip is a special-shaped product of the blank, mainly used in induction cookers and induction cookers. Referring to 11, the inner and outer sides of the curved arc of the curved magnetic strip are designed with protrusions, and the protrusions are required to be smooth and free of burrs. At present, after the curved magnetic strip is pressed, due to its special shape, workers often use a brush to repeatedly brush the protrusions of the curved magnetic strip to deburr it. However, manual deburring is slow, which reduces the production efficiency of the curved magnetic strip. Secondly, manual brushing cannot completely remove the hard burrs on the protrusions of the curved magnetic strip, resulting in a decrease in the quality of the curved magnetic strip. Therefore, a curved magnetic strip edge grinding device that can quickly remove burrs is proposed. Summary of the Invention

[0003] The purpose of this invention is to provide a device for grinding the edges of bent magnetic strips, so as to solve the technical problem that it is inconvenient to remove the protruding burrs at the bending arc during the forming process of bent magnetic strips.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A device for grinding the edge of a curved magnetic strip includes a curved magnetic strip with protrusions on both sides and a conveyor horizontally arranged below the curved magnetic strip with grooves on both sides.

[0006] A support component that moves along the chute of the conveyor is provided inside the chute of the conveyor. A guide rail connected to the conveyor is provided above the support component. A magnet is provided inside the conveyor and below the guide rail.

[0007] A drive component is provided inside the chute of the conveyor and on the side of the support component. A motor is provided above the drive component, and a brush is provided at the output shaft of the motor.

[0008] The guide rail has an opening near its end, and the position of the opening corresponds to the position of the motor.

[0009] The drive component includes a telescopic rod and a mounting component installed in the conveyor chute, wherein the extension distance of the telescopic rod corresponds to the shape of the curved magnetic strip.

[0010] Preferably, the guide rail has an opening with a shovel plate connected to the conveyor, and a baffle plate is provided at the opening of the guide rail and above the shovel plate, wherein one end of the shovel plate is inclined.

[0011] Preferably, there are two guide rails, both of which are S-shaped and have a gap between them, the gap being the size of the curved magnetic strip transport adapter.

[0012] Preferably, the opening side of the guide rail is bent, with a bending angle of 15 to 60 degrees.

[0013] Preferably, the length of the edge bristles of the brush is greater than the length of the bristles in the middle of the brush.

[0014] Preferably, the support component includes a support block connected to the transport machine and a connecting plate mounted above the support block and connected to the guide rail;

[0015] The connecting plate has two through holes on its surface, and the through holes are oblong.

[0016] The support block and the connecting plate position guide rail fixing components are provided, and multiple support components connected to the transport machine are provided on the side of the guide rail.

[0017] Preferably, the mounting component includes a fixing plate installed inside the conveyor chute and a mounting plate disposed at the top side of the fixing plate and connected to the motor. The bottom side of the fixing plate is provided with a connector that penetrates the fixing plate and is connected to the mounting plate and the telescopic rod at both ends respectively.

[0018] Preferably, a sliding groove is provided at the top center of the side of the fixing plate, and a slider that moves along the sliding groove of the fixing plate is provided below the mounting plate.

[0020] The beneficial effects of this invention are:

[0021] This invention uses a conveyor to move a bent magnetic strip along the gap of a guide rail. The magnetic force of the magnet reduces the moving speed of the bent magnetic strip at the opening of the guide rail. At the same time, a shovel lifts the edge of the bent magnetic strip, separating the protrusion of the bent magnetic strip from the conveyor. A baffle limits the bent magnetic strip to prevent it from falling off. A telescopic rod drives the connecting piece, allowing the mounting plate to slide above the fixed plate. The motor drives the brush to rotate while moving along the side of the bent magnetic strip, causing the rotating brush bristles to rub against the bent magnetic strip and polish the protrusion of the bent magnetic strip.

[0034] To make the technical means, creative features, achieved objectives, and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this invention and not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention.

[0035] Specific embodiments of the present invention are described below with reference to the accompanying drawings.

[0036] Example 1

[0037] This embodiment proposes a curved magnetic strip edge grinding device, including a curved magnetic strip 1 with protrusions on both sides and a conveyor 2 horizontally arranged below the curved magnetic strip 1 and having grooves on both sides.

[0038] A support component 4 is provided inside the chute of the conveyor 2, which moves along the chute of the conveyor 2. A guide rail 3 connected to the conveyor 2 is provided above the support component 4. It should be noted that there is no friction between the bottom end of the guide rail 3 and the conveyor 2. A magnet 8 is provided inside the conveyor 2 and below the guide rail 3. The magnet 8 is an electromagnet.

[0039] A drive component 6 is provided inside the chute of the transport machine 2 and on the side of the support component 4. A motor 5 is provided above the drive component 6, and a brush 7 is provided at the output shaft of the motor 5.

[0040] The guide rail 3 has an opening near its end, and the position of the opening corresponds to the position of the motor 5.

[0041] The drive component 6 includes a telescopic rod 62 and a mounting component installed in the slide of the conveyor 2, wherein the extension distance of the telescopic rod 62 corresponds to the shape of the curved magnetic strip 1;

[0042] The guide rail 3 has a shovel 9 connected to the conveyor 2 at its opening. A baffle 10 is provided at the opening of the guide rail 3 and above the shovel 9. It should be noted that one end of the shovel 9 is inclined, and the length of the shovel 9 is the same as the moving distance of the bent magnetic strip 1 at the opening of the guide rail 3. Accordingly, the bent magnetic strip 1 is placed at an inclined position at the opening of the guide rail 3.

[0043] For details, please refer to Figure 1-11 This example presents a device for grinding protrusions on bent magnetic strips. This grinding device integrates a chain conveyor 2, guide rail 3, motor 5, drive component 6, brush 7, scraper 9, and baffle 10. Its purpose is to use the conveyor 2 to move the bent magnetic strip 1 along the gap in the guide rail 3, and the magnetic force of the magnet 8 to reduce the speed of the bent magnetic strip 1 at the opening of the guide rail 3. Simultaneously, the scraper 9 scrapes up the edge of the bent magnetic strip 1, separating the protrusion from the conveyor 2. The grinding is then completed via a telescopic rod. 62 drives the connector 63, causing the mounting plate 65 to slide above the fixed plate 61. This causes the motor 5 to rotate the brush 7 while moving it along the side of the curved magnetic strip 1. The bristles of the brush 7 polish the protrusions of the curved magnetic strip 1. At the same time, the baffle 10 limits the curved magnetic strip 1 during deburring to prevent it from falling off. The magnetic force of the magnet 8 causes the debris to be attracted above the conveyor 2. The debris is discharged when the power is cut off, thus avoiding the problem of low efficiency in deburring the protrusions of the curved magnetic strip 1.

[0044] The following describes the specific structure of the guide rail 3, support component 4, brush 7, and mounting component involved in this example;

[0045] Please see Figure 1-6 There are two guide rails 3, both of which are S-shaped and have a gap between them. It should be noted that the gap size is the transport fit size of the bent magnetic strip 1. It should also be noted that the opening side of the guide rail 3 is bent, with a bending angle of 15 to 60 degrees. The bent slope of the guide rail 3 faces the bent magnetic strip 1 and guides the bent magnetic strip 1 at the opening of the guide rail 3.

[0046] Please see Figure 7-9 The length of the edge bristles of brush 7 is greater than the length of the bristles in the middle of brush 7. It should be noted that the edge bristles of brush 7 are in contact with the raised edge of the curved magnetic strip 1.

[0047] Please see Figure 1-10 The support component 4 includes a support block 41 connected to the conveyor 2 and a connecting plate 42 installed above the support block 41 and connected to the guide rail 3. The surface of the connecting plate 42 is provided with two through holes. It should be noted that the through holes are oblong holes. The bottom end of the support block 41 has a slider that moves along the slide of the conveyor 2. The support block 41 and the connecting plate 42 are fixed components of the guide rail 3, and multiple support components 4 connected to the conveyor 2 are provided on the side of the guide rail 3.

[0048] Please see Figure 7-8 The mounting components include a fixed plate 61 installed inside the slide of the conveyor 2 and a mounting plate 65 located at the top side of the fixed plate 61 and connected to the motor 5. The side of the fixed plate 61 and below the mounting plate 65 is provided with an elongated hole. The bottom side of the fixed plate 61 is provided with a connector 63 that passes through the fixed plate 61 and is connected to the mounting plate 65 and the telescopic rod 62 at both ends respectively. It should be noted that the top end of the connector 63 passes through the elongated hole and connects to the mounting plate 65. The top center of the side of the fixed plate 61 is provided with a sliding groove, and the bottom of the mounting plate 65 is provided with a slider 64 that moves along the sliding groove of the fixed plate 61.

[0049] The following section breaks down the sliding process of the brush 7 to the curved magnetic strip 1, taking into account the specific configurations of the guide rail 3, support component 4, brush 7, and mounting components:

[0050] ①Please refer to Figure 2 and Figure 6As the curved magnetic strip 1 is moved along the gap of the guide rail 3 by the conveyor 2 to the opening of the guide rail 3, and as the center of the brush 7 is aligned with the center of the curved magnetic strip 1, the telescopic rod 62 drives the connector 63 and the mounting plate 65 to make linear motion. The motor 5 and the brush 7 approach the curved magnetic strip 1 under the drive of the mounting plate 65, and make the brush 7 contact the curved magnetic strip 1. Through the rotational force of the motor 5, the bristles of the brush 7 rotate and rub against the curved magnetic strip 1, removing the burrs from the protrusions of the curved magnetic strip 1.

[0051] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
