Abstract

The invention discloses a tooth guard porous laser welding sheet and a preparation process thereof, belonging to the technical field of high-efficiency and energy-saving tools. The laser welding sheet includes a substrate, a chip removal groove, a chip removal cooling hole and a diamond cutter head. The part of the inner surface of the head is inclined, and the chip removal cooling holes are distributed on circular lines with different radii. The material of the substrate is 30CrMo; the raw material composition of the cutter head: 20-33 parts of copper, 28-44 parts of iron, 3-12 parts of nickel, 6-20 parts of cobalt, 3-11 parts of tin, 11-24 parts of rare earth alloy, 0.09-0.15 parts of liquid paraffin, 1.0-2.5 parts of diamond. The cutter head and the substrate are connected as a whole by laser welding. In the present invention, by optimizing the composition of the cutter head and the structure of the laser welding sheet, the prepared laser welding sheet can meet the use requirements of high efficiency and energy saving, and is environmentally friendly and safe.

Description

technical field [0001] The invention relates to the technical field of high-efficiency energy-saving tools, in particular to a porous laser welding sheet for tooth guards and a preparation process thereof. The laser welding sheet is mainly used for the construction of expressways and the cutting and maintenance of engineering bridges, demolition and construction of walls, and old concrete pavement renovation etc. Background technique [0002] In the rapidly developing market environment, safety and efficiency are essential requirements for laser welding sheets, especially when used in harsh environments, the safety of laser welding sheets is a constant theme. Ordinary saw blades are difficult to maintain safe stability because there is no tooth protection or only a small amount of hard alloy protection matrix, and the infrastructure construction is inseparable from laser welding blades. With the improvement of labor costs, high-efficiency and energy-saving tools are bound t...
