Description

Technical Field

[0001] This application belongs to the field of machining equipment technology, and particularly relates to a blocking structure and an online automated demagnetizing device including the structure. Background Technology

[0002] Generally, steel parts, such as various automotive parts, need to be demagnetized in the later stages of machining. The main reason is that if the parts have obvious magnetism, it will easily cause the following harmful effects: reduced measurement accuracy, adsorption of iron filings and impurities, and inconvenience in assembly.

[0003] Relatively efficient demagnetizing devices are generally the online, automated demagnetizing devices mentioned above. Their main structural components include a frame, a conveyor belt, and a demagnetizer. The demagnetizer is typically current-driven, using either alternating current (AC) or direct current (DC) demagnetizing methods to gradually disrupt the magnetic domains within the aforementioned components, thus achieving demagnetization.

[0004] The demagnetizer is roughly U-shaped. When the steel components pass under it, a certain demagnetization effect can be achieved. The conveyor belt is used to move the components.

[0005] On the other hand, in order to improve the demagnetizing effect, the parts can pass under the demagnetizer multiple times, and the placement angle on the conveyor belt is different each time, so as to obtain a relatively comprehensive demagnetizing effect.

[0006] For example, Chinese utility model patent with authorization announcement number CN 222354858 U and authorization announcement date of 2025.01.14 discloses a demagnetizing device for automotive parts, whose main structural components include: an operating table, a first conveyor belt, a second conveyor belt, a demagnetizer, a rotating plate, a motor, a push plate, a roller, a first cylinder, a rack, a gear, a drive shaft, a spring, a fixing block, and a second cylinder.

[0007] The demagnetizing device in this utility model patent has the following advantages: the parts can be flipped over by a rotating plate during the demagnetizing process, thereby saving demagnetizing time and improving the demagnetizing effect.

[0008] However, in actual use, this demagnetizing device has at least the following problems of being impractical and costly. Specifically, in order to achieve the effect of flipping the parts, the device is equipped with a complex overall structure, including two cylinders, which is relatively inefficient, troublesome, and costly. Utility Model Content

[0009] This application provides a blocking structure, the technical problem to be solved by which is to make the flipping action of steel parts during the demagnetization process simpler, more convenient and economical.

[0010] This application also provides an online automated demagnetizing device including the above-mentioned blocking structure.

[0011] The technical solution adopted by this application to solve the above problems is: a blocking structure, including a double-layer plate frame unit for clamping the side baffle of the demagnetizing device, a bottom frame unit with counterweight block disposed on the double-layer plate frame unit and replaced by the double-layer plate frame unit after the upper and lower positions are interchanged, for placement on the panel of the demagnetizing device, and a sleeve unit disposed on the double-layer plate frame unit and used for flipping the steel parts in the conveying by blocking.

[0012] A further preferred technical solution is that the double-layer plate frame unit includes two vertical plates that are parallel to each other and are disposed on the bottom frame unit with counterweight, and fastening bolts that are disposed on the two vertical plates and are used to clamp the side baffle of the demagnetizing device.

[0013] A further preferred technical solution is that the base frame unit with counterweight includes a rectangular frame with two vertical plates at one end, and a cuboid counterweight disposed within the rectangular frame and used for placement on the panel of the demagnetizing device.

[0014] A further preferred technical solution is that the sleeve unit includes a horizontal fixed tube disposed on one of the vertical plates, and an outer tube sleeved on the horizontal fixed tube and used to block steel components.

[0015] A further preferred technical solution is that the double-layer board frame unit further includes a transverse reinforcing plate disposed at one end of the vertical board and used to connect the end face of the rectangular frame.

[0016] A further preferred technical solution is that the base frame unit with counterweight also includes an internal threaded hole on the rectangular frame, which is provided on the rectangular frame and is installed with the fastening bolts that have been removed from the vertical plate, in order to push up the rectangular frame on the demagnetizing device panel.

[0017] A further preferred technical solution is that the sleeve unit further includes a protruding strip disposed on the outer side of the rectangular frame and having the internal threaded channel.

[0018] A further preferred technical solution is that the base frame unit with counterweight also includes an L-shaped grip groove for picking up and placing items, which is provided on the cuboid counterweight.

[0019] An online automated demagnetizing device including the aforementioned blocking structure includes a demagnetizing device side baffle, a demagnetizing device panel, a conveyor belt, and a demagnetizer. It also includes mounting holes disposed on the conveyor belt, protruding plates disposed in pairs on the conveyor belt and inclined to support steel components to reduce the difficulty of the sleeve unit in blocking and turning the steel components, and mounting blocks disposed on the lower surface of the protruding plates for inserting into the mounting holes.

[0020] A further preferred technical solution is that the protruding plate is replaced by an elastic rubber sheet attached to the conveyor belt and used to support the steel parts, and the elastic rubber sheet is also provided with a hemispherical protrusion to reduce the difficulty of the sleeve unit in preventing the steel parts from being turned over.

[0021] The beneficial effects of this application include at least the following five points.

[0022] First, the blocking structure, by placing the sleeve unit on the steel parts conveying path, makes the parts flipping function of the blocking method effective, and the flipping method is relatively simple, convenient and economical, without the need for cylinders, motors and other structures.

[0023] Secondly, the component flipping function of this blocking structure has a relatively wide range of applications. It can be installed and used on the side baffle and panel of the demagnetizing device, and the installation stability is sufficient.

[0024] Third, the sleeve unit not only has the feature of adjustable length, but also achieves height adjustment on the side baffle of the demagnetizing device through the double-layer plate frame unit.

[0025] Fourth, by replacing the fastening bolts, the height adjustment effect of the blocking structure remains effective on the demagnetizing device panel without affecting the positional stability of the structure.

[0026] Fifth, the above-mentioned demagnetizing device including the blocking structure has the advantage that steel parts are easily blocked and turned over, even if the shape of the steel parts is relatively difficult to turn over and is approximately cubic. Attached Figure Description

Detailed Implementation

[0039] The following description is merely a preferred embodiment of this application and is not intended to limit the scope of this application.

[0040] like Figures 1-10 As shown, a blocking structure includes a double-layer plate frame unit 1 for clamping the side baffle 11 of the demagnetizing device, a bottom frame unit 2 with counterweight block disposed on the double-layer plate frame unit 1 and replaced by the double-layer plate frame unit 1 after the upper and lower positions are interchanged for placement on the panel 12 of the demagnetizing device, and a sleeve unit 3 disposed on the double-layer plate frame unit 1 and used by blocking to flip the steel parts a in the conveying process.

[0041] In this embodiment, the specific components of the blocking structure include: one sleeve unit 3, one or two base frame units 2 with counterweights, and the same number of double-layer plate frame units 1 as the base frame units 2 with counterweights.

[0042] The main methods of using this blocking structure include the following two.

[0043] First, the double-layer plate frame unit 1 is located at the bottom, and the base frame unit 2 with counterweight is located at the top. The former is used to clamp the side baffle 11 of the demagnetizing device, while the latter is idle. The sleeve unit 3 is located on the conveying path of the steel component a, achieving the effect of blocking and flipping the steel component a, so that the demagnetizer 14 can achieve a more comprehensive demagnetizing effect. For details, please refer to the appendix. Figure 2 .

[0044] Secondly, the double-layer plate frame unit 1 is on top, and the counterweight base frame unit 2 is on the bottom. The latter is placed on the demagnetizing device panel 12. The former serves as the connecting structure between the counterweight base frame unit 2 and the sleeve unit 3. The sleeve unit 3 is located on the conveying path of the steel component a. Ultimately, this also results in a more comprehensive demagnetizing effect. For details, please refer to the appendix. Figure 3 .

[0045] The main material of the blocking structure is plastic, rubber, aluminum alloy or stainless steel, and the connection between the double-layer plate frame unit 1, the bottom frame unit 2 with counterweight and the sleeve unit 3 is integrally formed.

[0046] In addition, the following points need to be explained.

[0047] 1. In the conveying direction of steel component a, the blocking structure is installed upstream of demagnetizer 14 or inside its effective demagnetizing area.

[0048] 2. The installation height of the double-layer plate frame unit 1 on the side baffle 11 of the demagnetizing device is adjustable, and the length of the sleeve unit 3 itself is adjustable, so that the blocking and flipping effect of the blocking structure has a relatively wide range of applications for steel parts a of various shapes and styles.

[0049] 3. If steel component a is too heavy, the above-mentioned blocking and overturning effect will not apply.

[0050] 4. When there are two of each of the double-layer plate frame unit 1 and the base frame unit 2 with counterweight, one double-layer plate frame unit 1 and one base frame unit 2 with counterweight can form a complete fixing structure at one end of the sleeve unit 3, allowing the sleeve unit 3 to provide greater safety blocking strength for the steel component a. For details, please refer to the appendix. Figure 5 .

[0051] 5. When the sleeve unit 3 is in use, its length direction is generally perpendicular to the length direction of the conveyor belt 13.

[0052] 6. When the above two fixed structures are set on the left and right sides of the conveyor belt 13, they are independent of each other. That is, one of them can be a double-layer plate frame unit 1 on top and the other can be a double-layer plate frame unit 1 on the bottom. Correspondingly, the side baffles 11 of the demagnetizing device are not necessarily set in pairs.

[0053] The double-layer plate frame unit 1 includes two vertical plates 101 that are parallel to each other and are mounted on the bottom frame unit 2 with counterweight, and fastening bolts 102 that are mounted on the two vertical plates 101 and respectively with the sleeve unit 3 and are used to clamp the side baffle 11 of the demagnetizing device.

[0054] In this embodiment, the two vertical plates 101 are parallel to each other and are rectangular in shape, with the sleeve unit 3 perpendicular to them. Correspondingly, the length direction of the side baffle 11 of the demagnetizing device is generally parallel to the length direction of the conveyor belt 13.

[0055] One of the vertical plates 101 is provided with a screw hole for installing the fastening bolt 102, and the other vertical plate 101 is provided with the sleeve unit 3.

[0056] The base frame unit 2 with counterweight includes a rectangular frame 201 with two vertical plates 101 at one end, and a cuboid counterweight 202 disposed within the rectangular frame 201 and placed on the demagnetizing device panel 12.

[0057] In this embodiment, the cuboid counterweight 202 has a relatively large weight, which is used to effectively maintain the length direction of the sleeve unit 3 perpendicular to the length direction of the conveyor belt 13, so that the relatively heavy steel parts a can also be smoothly blocked and turned over.

[0058] The inner side of the rectangular frame 201 is fully close to the side of the cuboid counterweight 202. If the main material of the blocking structure is, for example, plastic, the cuboid counterweight 202 can be made of stainless steel to ensure the effectiveness of the "counterweight" function.

[0059] It should be noted that the double-layer board frame unit 1 is located at the bottom, and the base frame unit 2 with counterweight is located at the top. When the latter is not in use, the cuboid counterweight 202 can be removed from the rectangular frame 201 and placed on the demagnetizing device panel 12 for further storage, to prevent it from pressing the double-layer board frame unit 1 askew. For details, please refer to the appendix. Figure 2 .

[0060] The sleeve unit 3 includes a horizontal fixed tube 301 disposed on one of the vertical plates 101, and an outer tube 302 sleeved on the horizontal fixed tube 301 and used to block the steel component a.

[0061] In this embodiment, the transverse fixing tube 301 and the outer tube 302 can be either sleeved or screwed together. When the two are screwed together, the sleeve unit 3 further includes the aforementioned fastening nut 303 disposed on the transverse fixing tube 301 and used to clamp the outer tube 302.

[0062] Furthermore, the reason why the transverse fixing tube 301 and the outer tube 302 are designed as tubes rather than rods is that their effect of preventing the overturning of steel parts a relies on their structural strength and material rigidity, rather than their weight.

[0063] If the sleeve unit 3 is too heavy, it may press down on the double-layer plate frame unit 1, causing its appropriate blocking height to be changed.

[0064] The double-layer board frame unit 1 also includes a horizontal reinforcing plate 103 disposed at one end of the vertical plate 101 and used to connect the end face of the rectangular frame 201.

[0065] In this embodiment, the vertical plate 101, the horizontal reinforcing plate 103, and the rectangular frame 201 are integrally formed. The main function of the horizontal reinforcing plate 103 is to increase the connection strength between the vertical plate 101 and the rectangular frame 201, and to prevent the vertical plate 101 from tilting or even falling off the rectangular frame 201.

[0066] At this time, the overall shape of the vertical plate 101 and the horizontal reinforcing plate 103 is "L-shaped".

[0067] The base frame unit 2 with counterweight also includes an internal threaded hole 203 on the rectangular frame 201, which is provided on the rectangular frame 201 and is installed by means of the fastening bolts 102 that have been removed from the vertical plate 101, in order to push up the rectangular frame 201 on the demagnetizing device panel 12.

[0068] In this embodiment, the main function of the internal threaded channel 203 is: When this blocking structure is used with the double-layer plate frame unit 1 on top and the counterweight base frame unit 2 on the bottom, its cooperation with the fastening bolts 102 that have been removed from the vertical plate 101 allows the sleeve unit 3 to also provide vertical height adjustment functionality. This is something that the original counterweight base frame unit 2 without the internal threaded channel 203 could not achieve. For details, please refer to the appendix. Figure 5 .

[0069] However, the following three points need to be noted when implementing the above functions.

[0070] First, in this method, the number of fastening bolts 102 is at least two, and their size matches the internal threaded channel 203.

[0071] Secondly, generally speaking, when the upper limit of the rectangular frame 201 raised by the fastening bolt 102 is such that the rectangular frame 201 cannot fully fit the cuboid counterweight 202, the lifting function of the rectangular frame 201 cannot affect the stability of the entire bottom frame unit 2 with counterweight after it has been selected.

[0072] Third, the base frame unit 2 with counterweight may further include a nut to reinforce the tightness of the fastening bolt 102. The nut is applicable when the fastening bolt 102 clamps the side baffle 11 of the demagnetizing device and when the fastening bolt 102 lifts the rectangular frame 201.

[0073] The sleeve unit 3 also includes a protruding strip 204 disposed on the outer side of the rectangular frame 201 and having the internal threaded channel 203.

[0074] In this embodiment, the main function of the protruding strip 204 is to allow the diameter of the internal threaded channel 203 to be relatively large while ensuring the structural integrity and unbrokenness of the rectangular frame 201, so as to be used with the larger-sized fastening bolt 102, and ultimately provide a relatively greater threaded connection strength for the fastening bolt 102.

[0075] Conversely, without the protruding strip 204, the diameter of the internal threaded channel 203, for example, being 70% of the wall thickness of the rectangular frame 201, might already significantly reduce the structural strength of the rectangular frame 201.

[0076] Specifically, the cross-sectional shape of the protruding strip 204 is semi-circular or rectangular, and its length is equal to the vertical depth of the rectangular frame 201. The internal threaded channel 203 vertically penetrates the protruding strip 204.

[0077] The base frame unit 2 with counterweight also includes an L-shaped grip groove 205 for picking up and putting down the cuboid counterweight 202.

[0078] In this embodiment, the main function of the L-shaped gripping groove 205 for picking up and putting down is to make the loading and unloading of the cuboid counterweight 202 within the rectangular frame 201 more convenient and safer.

[0079] The rectangular counterweight 202 can be easily picked up and put down by inserting a hook into the L-shaped grip groove 205 or by reaching into the palm of the hand. See the attached document for details. Figure 4The width of the L-shaped gripping groove 205 for picking up and putting down does not need to be equal everywhere; it can generally include one vertical groove and one horizontal groove.

[0080] An online automated demagnetizing device including the aforementioned blocking structure includes a demagnetizing device side baffle 11, a demagnetizing device panel 12, a conveyor belt 13, and a demagnetizer 14. It also includes mounting holes 15 disposed on the conveyor belt 13, protruding plates 16 disposed in pairs on the conveyor belt 13 and inclined to support steel components a to reduce the difficulty of the sleeve unit 3 in blocking the flipping of steel components a, and mounting blocks 17 disposed on the lower surface of the protruding plates 16 for inserting into the mounting holes 15.

[0081] In this embodiment, the specific structure of the demagnetizing device includes: two side baffles 11, two panels 12, one conveyor belt 13, one demagnetizer 14, two rings of mounting holes 15, and 5-10 pairs of protruding plates 16.

[0082] Each of the protruding plates 16 is provided with two mounting blocks 17 for inserting into two mounting holes 15 to ensure that the protruding plate 16 is stably installed on the conveyor belt 13.

[0083] In addition, the protruding plate 16 is mainly used for inclined support of steel component a, which is generally cubic in shape. For details, please refer to the appendix. Figure 8 This ensures that the sleeve unit 3 can be relatively easily blocked from flipping.

[0084] On the other hand, the relatively long steel component a can be placed on the conveyor belt 13 or on the protruding plate 16 without affecting its inherent advantage of being easy to flip.

[0085] Finally, the side baffle 11 and the panel 12 of the demagnetizing device are both made of stainless steel and are integrally formed. The conveyor belt 13 is a rubber belt. The demagnetizer 14 is a commercially available product, such as an AC demagnetizer. The mounting hole 15 is a circular hole. The protruding plate 16 and the mounting block 17 are integrally formed and are made of plastic or rubber.

[0086] The protruding plate 16 has a hollow structure and a relatively small width, which reduces the load on the conveyor belt 13 and makes it less likely to fall off when the conveyor belt 13 turns.

[0087] The protruding plate 16 is replaced by an elastic rubber sheet 18 attached to the conveyor belt 13 and used to support the steel component a. The elastic rubber sheet 18 is also provided with a hemispherical protrusion 19 to reduce the difficulty of the sleeve unit 3 in preventing the steel component a from being turned over.

[0088] In this embodiment, another structural style of the demagnetizing device is: the protruding plate 16 is replaced by an elastic rubber sheet 18, which can provide a relatively large coefficient of friction to the bottom of the steel component a, making it easier for the sleeve unit 3 to block and flip it, rather than blocking and stopping it. Otherwise, the steel component a will accumulate more and more, which will be a safety hazard.

[0089] Correspondingly, the mounting block 17, the elastic rubber sheet 18, and the hemispherical protrusion 19 are integrally formed and made of plastic or rubber. The coefficient of friction of the elastic rubber sheet 18 is greater than that of the conveyor belt 13, which ensures the effectiveness of the aforementioned easy-to-turnover function. For details, please refer to the appendix. Figure 10 .

Within the scope of knowledge possessed by those skilled in the art, various modifications can be made without departing from the spirit of this application.
