Bar one end is connected, the inner cavity phase configuration of core pieces and mold.
According to the above scheme, the core pieces include that several section radius successively successively decrease conical blocks from top to bottom, described several
Conical blocks are provided with central through hole, and the conical blocks center of bottom is fixedly linked with described locating rod one end, remaining conical blocks is logical
It crosses central through hole to socket-connect with locating rod, and can be slided up and down along locating rod.
According to the above scheme, the attachment device includes several outer cranses and interior cranse, and the outer cranse is set to described adjacent
The outer wall junction of two groups of conical rings, the interior cranse are set to the inner wall junction of the two adjacent groups conical ring.
According to the above scheme, circumferentially uniform intervals are equipped with several notches, top for the upper surface of the top tapered ring of the mold
Backstop platform is equipped on 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-speed rail bearer ring, by high-speed rail
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
Tool, which applies, opens stress, so that each arc cone block is formed gap mold and opens in advance, eliminates mold closed-gap in demoulding, convenient
Mold is smoothly deviate from, and abrasion is reduced；Pressure quenching mold is put into high-speed rail bearing ring parts inner hole, mold outer cone by robotic arm pawl
Face reclines with high-speed rail bearer ring inner conical surface, forms line between arc flange collar and inner conical surface and contacts, and convenient for demoulding, reduces abrasion；It will
The core pieces of piecemeal are put into pressure quenching mold inner hole by locating rod, slide core pieces along pressure quenching mold inner conical surface
It is close to pressure quenching mold, the high-speed rail bearing ring forging by changing conical mold core number of blocks realization different inner diameters is secondary to be quenched
Fire, flexibly, the scope of application is wider for adjustment.
