The invention discloses a forming die for an automobile silence plate with a double-layer area and a machining method. The machining method comprises the following steps of: step (1). machining a mainguard plate in advance, specifically, determining the size of a main guard plate material sheet through CAE analysis; step (2). machining an auxiliary plate in advance, specially, determining the size of an auxiliary plate material sheet through CAE analysis; step (3). bonding the auxiliary plate, specially, finding the position of the auxiliary plate before machining relative to the main guard plate before machining through early CAE simulation analysis, coating an adhesive on the auxiliary plate, bonding the auxiliary plate to the corresponding position on the main guard plate, and enablingthe material sheets to flow while the two material sheets are bonded together through the adhesive; and step (4). performing stretch forming, specifically, placing the two bonded material sheets in the designed forming die, and performing one-time stretch forming on the two bonded material sheets. By means of the machining method of the automobile silence plate with the double-layer area, one-time forming of the automobile silence plate with the double-layer area can be achieved. The machining is convenient; the machining efficiency is high; and the machining precision of the automobile silence plate is improved to a certain extent.
Description
technical field [0001] The invention relates to an automobile mould, in particular to a forming mold and a processing method of an automobile sound-absorbing panel with double-layer regions. Background technique [0002] The car body is assembled with steel plate structure or other materials to form a closed space and compartment, and each car type has different design concepts due to the original factory, such as engine design, shock absorber system, intake and exhaust methods, doors, car body The compactness, etc., or static, or different road conditions will produce different noises, through the steel plate, car body resonance, sound amplification, excessive noise is uncomfortable, tinnitus, easy fatigue, or interfere with the original pleasant sound effect, etc., so it is necessary to do the sound insulation of the car. Therefore, with the original design and assembly conditions, plus various shock absorption, sound insulation and sound-absorbing materials, the unnecess...
