The invention relates to a voice diaphragm pressure bearing piece
stamping and
laser irradiation composite forming
machining device and a method of the device. The device is a composite device formed by combining an automatic grading
stamping forming die and a
laser irradiation heating system. Strip-shaped materials are fed and located under the control of an automatic feeding device. The voice diaphragm pressure bearing piece forming
machining process is divided into three continuous automatic grading steps of
punching,
laser irradiation heating forming and blanking. In a first
station, an edge pressing mechanism, a
punching male die and a fixed die plate are combined for
punching, so that a voice diaphragm pressure bearing piece is punched; in a second
station, a forming male die, the fixed die plate and restraint layer glass are combined to acquire a laser irradiation heating forming
station, a laser unit works, the strip-shaped materials are irradiated with lasers through the restraint layer glass, the strip-shaped materials are heated and softened through laser irradiation,
extrusion of the forming male die is conducted, and therefore the voice diaphragm pressure bearing piece is formed; in a third station, blanking is conducted, the voice diaphragm pressure bearing piece is blanked through a blanking male die. The voice diaphragm pressure bearing piece
stamping and laser irradiation composite forming
machining device is simple, practical and low in cost, the forming efficiency of the voice diaphragm pressure bearing piece is high, and the forming accuracy of the voice diaphragm pressure bearing piece is good.
