Abstract
Description
Technical Field
[0001] This utility model relates to the field of cutting and grinding tools, and in particular to a grinding wheel. Background Technology
[0002] A grinding wheel is a grinding tool, a disc-shaped hard abrasive made from a mixture of abrasive and bonding agents. Grinding wheels are commonly used for cutting metal materials. The grinding surface of the wheel acts directly on the metal material, grinding a notch until the metal is cut. Currently, grinding wheels have poor chip removal performance. Therefore, during the cutting process, chips accumulate between the grinding wheel and the metal material, increasing friction and accelerating wear, thus reducing the wheel's lifespan. Utility Model Content
[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a grinding wheel that improves the chip removal performance of the grinding wheel, thereby increasing its service life.

The plurality of first chip removal protrusions are circumferentially distributed around the axis of the grinding wheel body. The plurality of first chip removal protrusions are close to the edge of the grinding wheel body. The gap between any two adjacent first chip removal protrusions is used for chips to pass through.
[0005] It has at least the following beneficial effects:
[0006] The gap between any two adjacent first chip-removing protrusions is used for chip passage, meaning that a chip removal channel is formed between any two adjacent first chip-removing protrusions. This results in multiple chip removal channels formed by the multiple first chip-removing protrusions along the edge of the grinding wheel body. During the cutting process of metal materials, chips can enter these multiple chip removal channels and move along their edges, allowing for more efficient chip removal from the cutting area and preventing chip accumulation between the grinding wheel body and the metal material. This grinding wheel effectively prevents chip accumulation between the grinding wheel body and the metal material during cutting, enabling rapid chip removal from the cutting area, improving the chip removal performance of the grinding wheel, and consequently extending its service life.

The plurality of second chip removal protrusions are staggered with the plurality of first chip removal protrusions. The gap between any two adjacent second chip removal protrusions is used for chips to pass through.
[0009] According to the present invention, the grinding wheel of the present invention has a third arc surface and two second guide planes on its side. The included angle formed by the two second guide planes faces the outer peripheral surface of the grinding wheel body. Both second guide planes are tangent to the third arc surface, and the third arc surface protrudes towards the outer peripheral surface of the grinding wheel body.

[0026] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0027] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.
[0028] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0029] refer to Figure 1This utility model discloses a grinding wheel, including a grinding wheel body 400. A plurality of first chip removal protrusions 100 are provided on the upper surface of the grinding wheel body 400. The plurality of first chip removal protrusions 100 are circumferentially distributed around the axis of the grinding wheel body 400. The plurality of first chip removal protrusions 100 are close to the edge of the grinding wheel body 400. The gap between any two adjacent first chip removal protrusions 100 is used for chips to pass through.
[0030] In existing technologies, both the upper and lower surfaces of traditional grinding wheels are flat. During the cutting of metal materials with traditional grinding wheels, a relatively tight and flat cutting interface is formed between the grinding wheel and the metal material. At this point, only a tiny gap between the grinding wheel and the metal material serves as a chip removal channel. Because the space of the chip removal channel is very limited, when a large amount of chips is generated, the chip removal channel is easily filled with chips, preventing subsequent chips from being discharged smoothly and causing them to accumulate in the cutting area. Therefore, it can be seen that the chip removal performance of traditional grinding wheels is poor. Due to the poor chip removal performance of traditional grinding wheels, chips cannot be discharged from the grinding wheel and the metal material in a timely manner, leading to increased friction between the grinding wheel and the metal material, accelerating the wear rate of the grinding wheel, and making the abrasive grains in the grinding wheel more likely to fall off, thus reducing the service life of the grinding wheel.
[0031] It is understood that the gap between any two adjacent first chip removal protrusions 100 is used for chips to pass through, that is, a chip removal channel for chip removal is formed between any two adjacent first chip removal protrusions 100. Thus, multiple first chip removal protrusions 100 form multiple chip removal channels on the edge of the grinding wheel body 400. During the cutting of metal materials by the grinding wheel body 400, chips can enter multiple chip removal channels and move along the edges of the channels, allowing chips to be discharged from the cutting area more efficiently and preventing chip accumulation between the grinding wheel body 400 and the metal material. This grinding wheel can prevent chip accumulation between the grinding wheel body 400 and the metal material during cutting, allowing the chips generated during cutting to be quickly discharged from the cutting area, improving the chip removal performance of the grinding wheel, and thus helping to extend the service life of the grinding wheel.
[0032] On the other hand, when the grinding wheel body 400 rotates at high speed, the multiple first chip removal protrusions 100 evenly distributed on the edge of the grinding wheel body 400 increase the uneven distribution of mass at the edge of the grinding wheel body 400, thereby enhancing the effect of centrifugal force. This allows the chips to be more easily and quickly thrown off the surface of the grinding wheel body 400 under the action of centrifugal force, thus preventing chip accumulation at the edge of the grinding wheel body 400. Furthermore, the multiple first chip removal protrusions 100 can disperse the cutting force during cutting, making the cutting process more stable. Compared with traditional grinding wheels, the cutting force dispersion effect of the multiple first chip removal protrusions 100 can reduce excessive compression and deformation of chips caused by concentrated cutting force, making it easier for the chips to maintain a relatively intact shape. Chips with intact shapes are less likely to entangle with each other during the discharge process, thus allowing the chips to be discharged from the cutting area more smoothly.
[0033] refer to Figure 1 and Figure 2 The side of the first chip removal protrusion 100 includes a first arc surface 110 and a second arc surface 120. The first arc surface 110 coincides with the outer peripheral surface of the grinding wheel body 400, and the second arc surface 120 protrudes towards the center of the grinding wheel body 400. It should be explained that the two opposing planes in the thickness direction of the grinding wheel body 400 are the upper and lower surfaces of the grinding wheel body 400, respectively. The outer peripheral surface of the grinding wheel body 400 is the most important working surface of the grinding wheel, and its linear velocity is the highest, primarily used for cutting. It can be understood that the outer peripheral surface of the grinding wheel body 400 is used for cutting metal materials, and the first arc surface 110 on the first chip removal protrusion 100 coincides with the outer peripheral surface of the grinding wheel body 400, allowing the first arc surface 110 on the first chip removal protrusion 100 to also participate in cutting. On the one hand, the first arc surfaces 110 on the multiple first chip removal protrusions 100 and the outer peripheral surface of the grinding wheel body 400 participate in cutting simultaneously, dispersing the cutting force originally concentrated at the edge of the grinding wheel body 400 to each of the first chip removal protrusions 100. This reduces the cutting load borne by the grinding wheel body 400 and the multiple first chip removal protrusions 100, thus making it less likely for the cutting speed to decrease or jam due to excessive load under the same power drive, which is beneficial to improving the cutting efficiency of the grinding wheel. On the other hand, the second arc surfaces 120 on the first chip removal protrusions 100 protrude towards the center of the grinding wheel body 400. The second arc surfaces 120 can guide the chips, allowing the chips between two adjacent first chip removal protrusions 100 to move along the second arc surfaces 120, thereby making it easier for the chips to be discharged.
[0034] refer to Figure 1The upper surface of the grinding wheel body 400 is provided with a plurality of second chip removal protrusions 200. These protrusions are circumferentially distributed around the axis of the grinding wheel body 400. Each protrusion is located between the center of the grinding wheel body 400 and a plurality of first chip removal protrusions 100, with the protrusions 200 and 100 staggered. The gap between any two adjacent protrusions 200 is used for chip passage. It is understood that as the grinding wheel is used continuously, the diameter of the grinding wheel body 400 will continuously decrease. When the edge of the grinding wheel body 400 shrinks to the location of the protrusions 200, the gap between any two adjacent protrusions 200 also forms a chip removal channel. In other words, at this point, the protrusions 200 form multiple chip removal channels at the edge of the grinding wheel body 400. The corresponding technical effects will not be further elaborated here. On the other hand, refer to... Figure 3 Multiple second chip removal protrusions 200 are staggered with multiple first chip removal protrusions 100. During the cutting process, the multiple first chip removal protrusions 100 and the multiple second chip removal protrusions 200 together form a more complex chip removal channel. This allows chips to be discharged from the cutting area towards the center of the grinding wheel body 400 or in other directions through the chip removal channel, further improving chip removal efficiency and reducing chip accumulation in the cutting area. It should be explained that from... Figure 3 From the top view, α is the centerline of the first chip removal bump 100, β is the centerline of the second chip removal bump 200, and the multiple second chip removal bumps 200 are staggered with the multiple first chip removal bumps 100 respectively, which means that the centerline of α and the centerline of β form an angle, and the centerline of β is located in the middle of two adjacent first chip removal bumps 100.
[0035] refer to Figure 1 and Figure 2 The second chip removal protrusion 200 has a third arc surface 210 and two second guide planes 220 on its side. The included angle formed by the two second guide planes 220 faces the outer peripheral surface of the grinding wheel body 400. Both second guide planes 220 are tangent to the third arc surface 210, which protrudes towards the outer peripheral surface of the grinding wheel body 400. It is understood that during the cutting process involving multiple first chip removal protrusions 100, when chips splash onto the third arc surface 210, the third arc surface 210 guides the chips, allowing them to move along the third arc surface 210 to the two second guide planes 220, thus enabling the chips to move along the second guide planes 220 and ensuring that the chips are discharged from the grinding wheel body 400. In this embodiment of the invention, both second guide planes 220 are perpendicular to the upper surface of the grinding wheel body 400, and the bisector of the angle between the two second guide planes 220 coincides with the axis of the grinding wheel body 400.
[0036] refer to Figure 1 and Figure 2 The upper surface of the grinding wheel body 400 is provided with multiple third chip removal protrusions 300. These protrusions are circumferentially distributed around the axis of the grinding wheel body 400. Each third chip removal protrusion 300 is located between the middle of the grinding wheel body 400 and multiple second chip removal protrusions 200. The third chip removal protrusions 300 and the second chip removal protrusions 200 are staggered. The gap between any two adjacent third chip removal protrusions 300 is used for chip passage. The function of the third chip removal protrusions 300 is the same as that of the second chip removal protrusions 200, and will not be further elaborated here. The side of the third chip removal protrusions 300 includes a fourth arc surface 310 and two third guide planes 320. The included angle formed by the two third guide planes 320 faces the outer peripheral surface of the grinding wheel body 400. Both third guide planes 320 are tangent to the fourth arc surface 310, which protrudes towards the outer peripheral surface of the grinding wheel body 400. In this embodiment of the invention, both third guide planes 320 are perpendicular to the upper surface of the grinding wheel body 400, and the bisectors of the angles of the two third guide planes 320 coincide with the axis of the grinding wheel body 400. During the cutting process involving multiple first chip removal protrusions 100, the multiple first chip removal protrusions 100, multiple second chip removal protrusions 200, and multiple third chip removal protrusions 300 together form a more complex chip removal channel, allowing chips to be discharged from the cutting area towards the center of the grinding wheel body 400 or other directions through the chip removal channel, further improving chip removal efficiency and reducing chip accumulation in the cutting area. The functions of the third guide plane 320 and the fourth arc surface 310 will not be further elaborated here. It should be explained that from... Figure 3 From the top view, α is the center line of the first chip removal bump 100 and the third chip removal bump 300, β is the center line of the second chip removal bump 200, and the multiple third chip removal bumps 300 are staggered with the multiple second chip removal bumps 200 respectively, which means that the center line of α and the center line of β form an angle, and the center line of α is located in the middle of two adjacent second chip removal bumps 200.
[0037] refer to Figure 3 In this embodiment of the utility model, the upper surface of the grinding wheel body 400 is provided with a plurality of first chip removal protrusions 100, a plurality of second chip removal protrusions 200 and a plurality of third chip removal protrusions 300 from the outside to the inside.
[0038] refer to Figure 2The thicknesses of the first chip removal protrusion 100, the second chip removal protrusion 200, and the third chip removal protrusion 300 are all equal. In one embodiment of this invention, the thickness of the grinding wheel body 400 is 2.5mm to 3mm, and the thickness of the first chip removal protrusion 100 is 0.8mm to 1mm. Since the thicknesses of the first chip removal protrusion 100, the second chip removal protrusion 200, and the third chip removal protrusion 300 are all equal, their thicknesses are all 0.8mm to 1mm. In a preferred embodiment of this invention, the thickness of the grinding wheel body 400 is 3mm, and the thicknesses of the first chip removal protrusion 100, the second chip removal protrusion 200, and the third chip removal protrusion 300 are 0.8mm. It is understood that the thickness ratio of the first chip removal protrusion 100 to the thickness of the grinding wheel body 400 should not be too large to avoid generating a large unbalanced force when the grinding wheel rotates at high speed.
[0039] refer to Figure 1 The grinding wheel body 400 has a mounting hole 410 in the middle. It is understood that the mounting hole 410 is used for inserting the drive shaft of the driving device, allowing the grinding wheel body 400 to fit tightly with the drive shaft, thereby enabling the driving device to drive the grinding wheel body 400 to rotate at high speed. The axis of the mounting hole 410 is the axis of the grinding wheel body 400.
[0040] In this embodiment of the invention, the grinding wheel body 400, the first chip removal protrusion 100, the second chip removal protrusion 200, and the third chip removal protrusion 300 are integrally formed. To manufacture the grinding wheel of this invention, the abrasive is simply poured into a corresponding mold. The mold has cavities for forming the grinding wheel body 400, the first chip removal protrusion 100, the second chip removal protrusion 200, and the third chip removal protrusion 300. After the abrasive is poured into the mold, the mold is placed into a hot press mold for hot pressing, thus hot pressing out the grinding wheel of this embodiment of the invention, making the grinding wheel body 400, the first chip removal protrusion 100, the second chip removal protrusion 200, and the third chip removal protrusion 300 integrally formed. Further details are omitted here.
[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0042] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
