Abstract
An ultra-thin matrix of circular diamond saw with 3-6.5 mm of thickness is prepared through blanking, machining, quenching, pressure tempering, levelling and grinding. Its advantages are high productivity increased by 10-20%, low energy consumption decreased by 30%, and high utilization rate of raw material (increased by 10-15%).
Description
Technical field
The invention belongs to the metallic article field, relate generally to diamond saw blade.
Background technology
Diamond saw blade, particularly diamond circular saw blade have been widely used in the cutting processing of nonmetal hard construction material (as marble, granite, cement products etc.).Diamond saw blade is made up of diamond block and saw bit matrix two parts.The connecting shaping of diamond block and matrix (steel) has three kinds of methods usually: ratio-frequency welding connection, method of laser welding and sintering process.
In the technical indicator of diamond circular saw blade, except mechanical property, outside rigidity, the flatness, the thickness of saw blade also is the key index that non-metal hard construction material processing industry is concerned about, because the thickness of saw blade directly influences the utilization rate of cutting processing efficient, energy consumption and raw material (waste material) to this class construction material.Saw blade thickness reduces, and then cutting processing efficient increases, and energy consumption reduces, and utilization rate of raw materials improves, and economic benefit rises.
Reducing of diamond disc thickness mainly is the minimizing of saw bit matrix thickness.Under the matrix of identical material, the minimizing of matrix thickness will cause rigidity to descend, and the bearing load ability reduces, until losing normal cutting processing ability.Therefore, under the situation that guarantees saw bit matrix rigidity, seeking the thinnest saw bit matrix is that people pay close attention to, particularly large diameter saw bit matrix.
Over nearly this year, people are studying slim diamond saw blade substrate always, have also obtained certain achievement.
In the prior art, the slim circular saw blade substrate of diamond is thinned to thickness below the setting from ISO6105 and GB11270 standard on external diameter matrix of the same race, general attenuate amount 0.7mm, maximum attenuate amount has reached 3.7mm, and the thickness of existing slim circular saw blade substrate has reached following index:

4, exert pressure
After matrix quenches in machine oil, enter in the forcing press immediately and exert pressure, the pressure of exerting pressure is 1.5～50kgf/cm
2, the time of exerting pressure is 5～30 minutes.
5, tempering
After matrix was exerted pressure, many overlapping was clamped in the anchor clamps, puts into tempering furnace together with anchor clamps and carries out temper.Temperature is 350～460 ℃, tempering time 4～8 hours.
6, smooth, roll and check
Matrix carries out finish turning, grinding, smooths and rolls after tempering, and on four unification inspection machines, flatness, the end of matrix is jumped into row and proofreaied and correct.
Adopt manufacture method of the present invention can produce with the thinner ultrathin diamond circular saw film base body of thickness under the diameter.The technical indicator that is reached is as shown in table 1:
