Riveting terminal bad phenomenon analysis ( On)

1, riveting terminal contact material overflow 2, riveting gap: the second step under the riveting die and take off the board didn't killed. 3, contact grooves, the first stop on pre rivet contact thickness is too thin, leading to the second step contact at the bottom of the cavity is less than 4, shrapnel deformation: because the bottom hole is too small a second step the unbroken much too big expansion is expected to lead to deformation of the shell off 5, contact: 1: the first step in advance riveting to play enough, 2: feed plate gasket is easy to loose. 6, contact filamentous crushed: because the concentricity of two-step riveting is not exactly the same, the first step after riveting contact diameter is larger, which leads to the second step cavity edge cut excess stock. 7, contact the fan crushed: rivet on the vibration plate of the knot, the knot between vibration plate and mold. Displacement or vibration plate line breadth too big blow. 8, the contact surface is not smooth, when refueling cavity or oil foreign body in it. 9, slow speed when the rivet into a mold: mold inside air pressure is too big, at the time of forward, the pressure will also block behind the rivet to walk forward. 10, riveting terminal rivet in vibration disc fall down: after vibration plate used for too long, some dirty things in the corner of the orbit, blocking the rivet to walk forward. More than 20 years experience in mold design team of engineers, break through the stamping industry technical difficulties, but production mould automatic riveting terminal parts, automatic mould tapping parts, precision stamping mould injection terminals, etc. Precision contact: wish you a prosperous business, everything goes well, if you want to learn more dynamic, can scan the qr code, pay attention to the public. , is committed to precision stamping processing factory of the world's most professional electronic components
