Problems solved by technology

During the preparation process, although the transition layer powder and the working layer powder come from different silos, after being put into the mold cavity, due to the fluidity of the powder, it is inevitable that the diamond in the working layer will flow to the transition layer, and the

Embodiment 1

[0061] The serrated diamond bit of the present embodiment, as figure 1 As shown, it includes a diamond-free transition layer 1 and a diamond-containing working layer 2, and the junction 3 between the transition layer 1 and the working layer 2 is a sawtooth structure; meanwhile, the working surface 4 of the working layer 2 is also sawtooth structure. The protrusions and recesses of the sawtooth structure have side walls that stop and fit in the circumferential direction of the cutter head. The welding surface of the transition layer 1 used for welding with the substrate is a curved surface concave toward the cutter head.

Embodiment 2

[0063] The square-wave diamond cutter bit of the present embodiment, as figure 2 As shown, it includes a transition layer 1 without diamond and a working layer 2 containing diamond. It is a square wave structure. The protrusions and depressions of the above-mentioned square wave structure have side walls that stop and fit in the circumferential direction of the cutter head. The welding surface of the transition layer 1 used for welding with the substrate is a curved surface concave toward the cutter head.

Embodiment 3

[0065] The wavy diamond cutter head of the present embodiment, as image 3 As shown, it includes a diamond-free transition layer 1 and a diamond-containing working layer 2, and the joint 7 between the transition layer 1 and the working layer 2 is a wave structure; meanwhile, the working surface 8 of the working layer 2 is also Wavy structure. The above-mentioned protrusions and depressions of the corrugated structure have side walls that stop and fit in the circumferential direction of the cutter head. The welding surface of the transition layer 1 used for welding with the substrate is a curved surface concave toward the cutter head.

Abstract

The invention discloses a diamond tool bit, a preparation method of the diamond tool bit, a cold pressing mold for a diamond tool bit, and a diamond saw blade. The diamond tool bit comprises a transition layer which does not contain diamonds and a working layer containing diamonds. A concave-convex structure is arranged at the joint of the transition layer and the working layer. According to the diamond tool bit, the transition layer which does not contain diamonds and the working layer containing diamonds are engaged mutually through the concave-convex structure, the bonding area of the transition layer and the working layer is increased, and the bonding strength between the transition layer and the working layer is high; and meanwhile, according to the diamond tool bit of the structure, the transition layer or the working layer can be independently formed at first during cold press molding, the situation that the transition layer and a substrate welding face include diamonds due to the fact that transition layer powder and working layer powder are simultaneously put into a mold cavity is avoided, and the effect that the transition layer does not contain diamonds is ensured, so that guarantees are provided for subsequent welding quality on the basis that the bonding strength of the transition layer and the working layer is also considered.

Description

technical field [0001] The invention belongs to the technical field of superhard material tools, and in particular relates to a diamond cutter head and a preparation method thereof, and also relates to a cold pressing mold for a diamond cutter head, and a diamond saw blade using the diamond cutter head. Background technique [0002] Diamond saw blade is a cutting tool, which is widely used in the processing of hard and brittle materials such as concrete, refractory materials, stone, ceramics, etc. The diamond saw blade is mainly composed of two parts: the substrate and the cutter head; the substrate is the main supporting part of the bonding or welding cutter head, and the cutter head is the part that cuts during use and is continuously consumed during use. According to the preparation process, diamond saw blades are classified into sintered diamond saw blades, welded diamond saw blades and electroplated diamond saw blades. Among them, the welding of diamond saw blades is m...
