Description
Technical field
The utility model relates to a kind of RS series to draw the formula seal plug that rises, and belong to the fabrication hole sealing technique in auto industry
Field.
Background technique
Most of existing auto industry class fabrication hole sealing technique uses steel ball sealing, concrete operations are as follows: steel ball is by sending
Material mechanism separates one by one, falls by gravity, into the feed bin of pressure head front end, which determines that position rests on steel ball by spring
Steel ball is pressed into fabrication hole by bottom using the steel ball feed device of spring mechanism.Or steel ball by feeding mechanism one by one
Steel ball is pressed into hole in piece part by a common oil cylinder pushing press-loading head after separation, is pressed process: after part clamps in place,
Steel ball feeding cylinder is moved to press fitting position, and steel ball is sent into the feed bin before pressure head, and at this moment press-loading head stops in situ, warp
It crosses hydraulic valve after being delayed several seconds and commutates and provide pressure to oil cylinder, pressure head, which advances, is pressed into steel ball in workpiece, oil cylinder during this
Stroke is controlled by buting iron.
Steel ball sealing requires the surface hardness of steel ball used and circularity to want up to standard；The metal contact surface of sealing hole and steel ball is hard
Degree will be slightly less than steel ball surface hardness, while guarantee contact surface circularity, and contact as far as possible for line, be contacted by steel ball to line
The mill pressure in face reaches the full contact in spherical surface and line face to realize sealing.
Steel ball sealing has following defect: steel ball has leakage pressure risk, the event in the case of the bored plug leakage of cylinder head water jacket
Hindering reason 65% is steel ball leakage pressure；Steel ball sealing mode is linear sealing, after engine operating vibration, there is very high leakage wind
Danger.
