Cross central through hole to socket-connect with locating rod, and can be slided up and down along locating rod.
By such scheme, the attachment means include several outer cranses and interior cranse, and the outer cranse is located at described adjacent
The outer wall junction of two groups of conical rings, the interior cranse is located at the inwall junction of the two adjacent groups conical ring.
By such scheme, circumferentially uniform intervals are provided with several notches, top for the upper surface of the top tapered ring of the mould
Backstop platform is provided with the outside of the top edge of portion's conical ring.
The beneficial effects of the invention are as follows：The present invention provides a kind of pressure quenching mold component of high ferro bearer ring, by high ferro
The radial and axial modularization of bearer ring pressure quenching mold, array conical ring is by inside and outside cranse spicing forming type, and interior cranse is to mould
Stress is opened in tool application, each arc is bored block formation gap mould and opens in advance, mould closed-gap is eliminated in the demoulding, convenient
Mould is smoothly deviate from, and reduces abrasion；Pressure quenching mold is put into by high ferro bearing ring parts endoporus, mould outer cone by robotic arm pawl
Face is reclined with high ferro bearer ring inner conical surface, and linear contact lay is formed between arc flange collar and inner conical surface, is easy to the demoulding, reduces abrasion；Will
The core pieces of piecemeal are put into pressure quenching mold endoporus by locating rod, core pieces is slided along pressure quenching mold inner conical surface
It is close to pressure quenching mold, realizes that the high ferro bearing ring forging of different inner diameters is secondary by the conical core rod number of blocks of change and quench
Fire, adjustment is flexible, and the scope of application is wider.
