Detailed Description

In order to enable those skilled in the art to better understand the technical solutions of the present application, the technical solutions of the present application are further described below with reference to the accompanying drawings and examples.

Referring to fig. 1 to 5, a grinding wheel type diamond saw blade includes a base 1 having a fitting center hole 101, through which the base 1 of the fitting center hole 101 can be integrally fitted to a cutting apparatus with the base 1 and the saw blade.

As shown in fig. 1-2, the surface of the base 1 is sequentially divided into a clamping surface 1a, a grinding surface 1b and a cutting side circumferential surface 1c by the assembly center hole 101 towards the circumferential side direction of the base 1, wherein the clamping surface 1a is used for being matched with cutting equipment to integrally fasten and clamp a saw blade, and the cutting strength of the saw blade in the cutting process is ensured, so that the stress deformation of the saw blade is avoided; the cutting side peripheral surface 1c is positioned at the periphery of the base body and is used for contacting with an object to be cut for cutting; the grinding surface 1b is used for synchronously carrying out contact grinding on two sides of the cutting seam after the cutting side peripheral surface 1c is cut, so that synchronous cutting and grinding are realized, the problems that the grinding precision is affected due to deflection of the cutting seam during later-stage independent grinding are solved, and the operation procedures and the operation time length of independently grinding two sides of the cutting seam are increased at present are effectively solved, the operation efficiency of cutting and later-stage grinding is greatly improved.

In order to improve the grinding efficiency and accuracy, as shown in fig. 1 to 3, a grinding structure is provided on the grinding surface 1 b. Specifically, the grinding structure is grinding sheets 2 which are uniformly distributed on the grinding surfaces 1b at two sides of the substrate 1 and have a diamond grid structure, the surface of the grinding sheets is a grinding surface, diamond particles are embedded in the grinding sheets, and the grinding sheets can be cut along with the previous step to quickly grind cutting seams. The grinding piece 2 is uniformly provided with a plurality of diamond holes 201, the side edge of each diamond hole 201 is provided with a grinding blade 2a, and the diamond holes can realize a certain cutting effect on the end face of the cutting seam so as to assist the grinding surface to realize rapid grinding, and solve the problem that the grinding surface is difficult to effectively grind the end face of the uneven cutting seam.

In order to meet the requirements of different grinding precision of the two end surfaces of the cutting seam (generally, when cutting the end of the blank, the cut end is abandoned so as to ensure that the cut end is flat), therefore, as shown in fig. 1-2 and 4-5, the radial width of the grinding sheet 2 on one side is larger than that of the grinding sheet 2 on the other side, wherein one side of the wider grinding sheet 2 contacts the end surface after cutting, while the narrower grinding sheet 2 is usually used for contacting the end surface of the cutting seam after cutting, so that the wider grinding sheet 2 grinds the end surface of the reserved cut object for a longer time so as to improve the precision of the end surface after cutting, and the cut end surface contacts the narrower grinding sheet 2 so as to reduce the grinding resistance and quicken the cutting and synchronous grinding time.

In order to further improve the grinding accuracy of the remaining end face of the object to be cut, as shown in fig. 3 to 4, the diamond-shaped holes 201 of the grinding sheet 2 on the wider side are gradually increased from the holding face 1a to the outer peripheral direction of the base body 1. The structure makes the diamond-shaped holes 201 close to the cutting side peripheral surface 1c larger, so each diamond-shaped hole 201 is provided with a longer grinding edge 2a, and an effective re-cutting effect can be realized on the cut rough end surface, so that the cut end surface gradually tends to be flat; the diamond-shaped holes 201 close to the clamping surface 1a are gradually reduced, the length of the grinding edge 2a of each diamond-shaped hole 201 is reduced, the area of the grinding surface is increased, and the grinding effect is never improved, so that the diamond-shaped hole 201 structure with gradually changed size can accelerate the grinding efficiency of the cutting end surface along with the cutting process and ensure the grinding quality.

In the cutting process, the surface of the saw blade is in a close contact state with the cutting seam, and the contact state is still maintained after the cutting is completed, in order to facilitate the separation of the saw blade from the cutting end surface, as shown in fig. 4-5, each side of the clamping surface 1a is lower than the height of the grinding piece 2 on the corresponding side, and the structure ensures that only the grinding pieces 2 on two sides are in contact with the end surface of the cutting seam in the cutting and grinding processes, and the clamping surface 1a is separated from the end surface of the cutting seam, so that the contact resistance can be effectively reduced, and the stop operation can be performed after the saw blade is separated from the cutting end surface rapidly.
