Description

Method for manufacturing horn vibrating piece

The present invention relates to a manufacturing method, and more particularly to a method of manufacturing a horn vibrating piece.

However, when the horn vibrating piece is elastic, the processing method is generally such that the rolled material is impregnated with the liquid resin, taken out, dried, and then wound into a spare cloth. When the elastic wave is to be manufactured, the conveying machine is used to pull the rolled material to the position of the forming mold, and when the cloth corresponds to the position of the forming mold, the mold is stopped, and then the upper mold and the lower mold of the forming mold are clamped to each other. So that the cloth material is pressed between the upper and lower molds; the upper and lower molds are also provided with heating means, and when the upper and lower molds are closed and the cloth material is pressurized, the heating device is also energized to make The lower molds are all raised in temperature, so that the resin-containing cloth material is softened by heating, and the elastic wave shape is formed by pressurization, and the elastic wave profile is cut at the same time of forming, or another A process cuts the contoured elastic wave to obtain the desired final component.

Moreover, when the molding die is heated under pressure, the heating temperature required is about 200 ° C, and the pressing heating time is about 10 seconds each time; in other words, each set of molds stays on the cloth. The minimum time for molding is 10 seconds, only six zeros can be formed in one minute. Only three hundred and sixty can be formed per hour.
