Wherein: 1. the polycrystalline diamond composite sheet comprises a base body 2, a base body mounting surface 3, a polycrystalline diamond composite sheet 4, a polycrystalline diamond composite sheet mounting surface 5, an alloy base body 6, a polycrystalline diamond layer 7, a convex strip or groove 8, an acute-angle structure 9, an upper rounded corner structure 10, a lower rounded corner structure 11 and a buckle.
Detailed Description
The invention will be further described with reference to the accompanying drawings.
As shown in fig. 1, 2, 3, 4, 5, 6 and 7, the cutter head for the chain arm saw comprises a substrate 1 made of steel or hard alloy, wherein a substrate mounting surface 2 is arranged on the substrate, a polycrystalline diamond composite sheet 3 is arranged on the substrate, a polycrystalline diamond composite sheet mounting surface 4 is arranged below the polycrystalline diamond composite sheet, the polycrystalline diamond composite sheet comprises a lower alloy substrate 5 and an upper polycrystalline diamond layer 6, and the substrate mounting surface is connected with the polycrystalline diamond composite sheet mounting surface; the method is characterized in that: the installation surface of the base body is provided with a convex strip or a groove 7, and the installation surface of the polycrystalline diamond composite sheet is provided with a groove or a convex strip matched with the convex strip or the groove.
The invention adopts mortise and tenon structure, increases the strength of the synthetic sheet and the spliced alloy or steel, and can achieve the aim of the invention.
Further, the protrusion is formed by a snap 11 with a thin middle part, the snap is arranged in a groove of the base body mounting surface, and the snap on the base body mounting surface is formed with the protrusion, as shown in fig. 8.
That is, the substrate mounting surface is provided with a groove, the polycrystalline diamond composite sheet mounting surface is also provided with a groove, and the two grooves are connected by a thin middle buckle.
Furthermore, the convex strip section of the substrate mounting surface 2 or the polycrystalline diamond composite sheet mounting surface has a structure with a wide part width and a narrow root part far away from the root part. As shown in fig. 2, 3, 5, 6.
That is to say, the structure of the polycrystalline diamond composite sheet above cannot be pulled out after the base body mounting surface and the polycrystalline diamond composite sheet mounting surface are combined, so that the connection is firmer.
Furthermore, the convex strip section of the substrate mounting surface 2 or the polycrystalline diamond composite sheet mounting surface 4 is of a rectangular structure. As shown in fig. 4.
Therefore, the connection is simpler and the installation is more convenient.
