Raw blade automatic cold-pressing forming method for diamond saw blade

Abstract

The invention discloses a raw blade automatic cold-pressing forming method for a diamond saw blade. The raw blade automatic cold-pressing forming method comprises the following steps that a cover plate is prefabricated, a positioning column is arranged in the middle of the cover plate, and a column groove containing the positioning column is formed in the center of a lower mold core; during pressing, the positioning column of the cover plate is sleeved with a center hole of a base body of the diamond saw blade to be placed into the lower mold core, and the base body is fixed to the lower moldcore through the cover plate; powder sweeping is conducted, so that great-wall-like teeth of the base body are pre-buried into diamond alloy powder; automatic pressing is conducted, an upper mold coreand an upper pressing head move downwards, when the upper mold core moves to the surface of the cover plate, the lower mold core moves downwards, and the upper pressing head enters a groove containing cavity to form a sealed space; and after pressurization, the powder and the base body are combined together, after pressure maintaining for a multiple seconds, the upper pressing head and the uppermold core rise, the cover plate and a raw blade stay at the lower mold core, and a demolding procedure is started to push the raw blade out. The raw blade automatic cold-pressing forming method has the advantages that uneven distributing of the powder above and below the great-wall-like teeth is avoided, the quality of the saw blade is improved, and the security coefficient of the saw blade is increased.

Description

technical field [0001] The invention relates to an automatic cold-press forming method for a green diamond saw blade, which belongs to the technical field of diamond saw blades. Background technique [0002] Now when the factory is producing diamond saw blades, the previous process is cold-pressed and formed, and manual pressing has been eliminated. At present, automatic cold-pressed forming is widely used. [0003] The existing automatic cold forming technology is carried out according to the following steps: Step 1, powder sweeping: according to the preset groove volume, the equipment automatically adds diamond alloy powder and automatically sweeps the powder surface to be equal to the surface of the lower mold core; Step 2 , the upper core of the diamond saw blade substrate is adsorbed by the magnet 10 and moves downward, and the upper pressure head also moves downward. Open the powder into the inside of the powder, and the part of the discharged powder rolls to the top ...

AI Technical Summary

Problems solved by technology

[0004] The disadvantage of this current technology is: when the base body discharges the powder downward, less powder rolls to the surface of the Great Wall tooth, resulting in uneven distribution of powder on the top and bottom of the Great Wall tooth, which seriously affects the quality and safety factor of the saw blade.
