Abstract
The invention discloses a method for processing a fracture type halving sealing ring. The method is characterized in that a brittle material is selected to process and form a round sealing ring, and a stress concentration notch is formed along a set fracture surface position of the round sealing ring and is symmetrical around the center of the ring; drawing or impacting force is applied along a direction which is vertical to a set fracture surface so as to expand the fracture, so that two halving rings are formed; and the two halving rings are spliced with each other through the corresponding fractures so as to form the fracture type halving sealing ring. The method utilizes the natural forming fracture to position and seal, so that accurate positioning can be realized and a sealing effect can be ensured in the installation and use processes of the fracture type halving sealing ring.

Described edge perpendicular to the direction applying stretching of the section drafted or the method for impulsive force is:
Rounding seal ring set is contained on diminished shaft, keep described diminished shaft for maintaining static, described diminished shaft the vertex of a cone at one end apply pressure vertically towards the end face of described rounding sealing ring, make described rounding sealing ring and diminished shaft generation relative displacement, until described rounding sealing ring is broken as point ring in two lobes;
Or be: keeping described rounding sealing ring for maintaining static, bottom the cone of described diminished shaft, applying pressure vertically, make described rounding sealing ring and diminished shaft generation relative displacement, until described rounding sealing ring is broken as point ring in two lobes.
Or be: in the symmetric position of the inner peripheral surface of described rounding sealing ring, and concentrate breach to be 90 ° with described stress to distribute, arrange a pair backing plate; Arranging between described a pair backing plate can radial extent driving mechanism, starts described driving mechanism and described a pair backing plate is being stretched along the direction perpendicular to section or support is risen described rounding sealing ring, until described rounding sealing ring is broken as point ring in two lobes.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, point sealing ring in adopting the inventive method to manufacture, avoids complicated high-precision machining;
2, the present invention implements location and sealing by utilizing the fracture of self-assembling formation, and it is installed and use procedure energy precise positioning also can ensure sealing effectiveness.
