Title: Method for drawing forming
Inventor: NUMAMOTO TERUO
IPC: B21D22/26
Filed: 1988-02-01
Abstract: PURPOSE:To perform stable forming by pressingly holding the periphery of a work onto a die and also pressingly holding the about central point of a part to be recessed of the work and then forming the part into a recessed, stepped shape by use of a die and punch for drawing the panel-shaped work into a recessed, stepped shape having both open sides. CONSTITUTION:When a work W is put on a die 2 and a slide is moved down, the work W abuts on a projection 3a and a pressing part 3b of a blank holder 3 and the work W is made to be a bent shape along the shape of the die 2. Then, the total periphery of the work W is pressed and held on the die 2 by the blank holder 3 and the center of a recessed part A is pressingly held on the die 2 by a pressing part 3b. The work W is brought to be in a good shape in which both the sides of the work W are uniform along the die shape without prebending, so that deformations easily formed in the recessed part by the pressing part 3b during holding the work W by the holder 3 are prevented from generation. The recessed part A is succeedingly reduced by a punch down moved to form the work W having recessed stepped shape with both open sides. Hence, the work W is formed without lapped wrinkles and cracks.

Then an Ni film is laminated onto the 1st layer W film except the part of the ceramic film 8 with plating or the like. Thus, the Ni film is not exposed by the ceramic layer 8 to the bonding face between the ceramic substrate 2 and the ceramic cover 3 and the bonding face of both is formed entirely by a ceramic. Since the ceramic is an oxide similar to a low melting point glass to offer excellent compatibility and the air-tight sealing is ensured to all the bonding face, the aging characteristic is improved and a highly reliable crystal vibrator is obtained.
