Detailed Description

In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following embodiments.

As shown in fig. 3-6, a diamond grinding block is provided, which includes a bolt 1, and a substrate layer 2, a buffer layer 3, a transition layer 4 and a grinding block layer 5 sequentially disposed from top to bottom, wherein the transition layer 4 is provided with a plurality of first through holes 41 for the bolt 1 to pass through, the tail of the bolt 1 sequentially passes through the first through holes 41, the buffer layer 3 and the substrate layer 2, and the tail of the bolt 1 is locked with a nut 6 on the substrate layer 2. The head of the bolt 1 is in a circular truncated cone structure, and the head of the bolt 1 is embedded in the grinding block layer 5.

Like this, this neotype head of bolt can bulge transition layer 4 lower surfaces, in actual production, bolt 1 and transition layer 4, put into 5 forming die on abrasive brick layer after buffer layer 3 and stratum basale 2 are connected, can fill up transition layer 4 lower surfaces during the sintering shaping after the raw materials is injected in the mould, consequently, form the looks block state of direction about with bolt 1 head in 5 shaping backs on abrasive brick layer, the dovetail fluting process of transition layer 4 has so been saved, the production efficiency of diamond abrasive brick has been improved, and it is fixed more comprehensive.

Further, the head of the bolt 1 is provided with a first round surface 11 and a second round surface 12 connected with the column part of the bolt 1, and the diameter of the first round surface 11 is larger than that of the second round surface 12, so that the head of the bolt 1 is in a truncated cone structure, after the diamond grinding block is formed, the head of the bolt 1 is embedded into the grinding block layer 5, and the truncated cone structure limits the grinding block layer 5 to move in the up-down direction and the left-right direction, so that the grinding block layer 5 and the transition layer 4 are fastened together.

Preferably, the transition layer 4 is also provided with a plurality of second through holes 42, so that the raw material of the grinding block layer 5 can be injected into the second through holes 42, and the grinding block layer is sintered and then forms a clamping state with the second through holes 42 in the left and right directions, so that the grinding block layer 5 and the transition layer 4 are further limited and offset in the left and right directions, the connection is firmer, the punching process is quick and simple, and the whole processing efficiency is not influenced.

Furthermore, the first through holes 41 are three and arranged in rows, the second through holes 42 are eight and are equally divided into two rows, and the two rows of second through holes 42 are respectively arranged on two sides of the first through holes 41.

Furthermore, each row of the first through holes 41 or the second through holes 42 are arranged at equal intervals, so that stress on each connection point between the module layer 4 and the transition layer 4 is more uniform during operation, and the module layer 4 is prevented from falling off or being damaged.

Further, the transition layer 4 is the cambered surface setting, the cambered surface can share the effort for bolt 1 at the 5 during operations on abrasive brick layer, avoids bolt 1 to receive the great effort on abrasive brick layer 5 and fracture the damage, prolongs diamond abrasive brick's life.

The above embodiments and drawings are not intended to limit the form and style of the present invention, and any suitable changes or modifications made by those skilled in the art should not be construed as departing from the scope of the present invention.
