Limited post, pressing mold forms the forming tank corresponding with resistance ring close to limited post side, and pressing mold is provided with anti-close to body one end
The escape groove only collided with water side.
By using above-mentioned technical proposal, the main body of fire-fighting joint is set on limited post, so as to which radially fixation disappears
Anti- joint, then fire hose and collar are once set in connection end, start hydraulic cylinder, pressing mold forces radial contraction to make collar
Contraction distortion is simultaneously pressed on limited post, so as to which fixed clamp is in fire hose between the two；During this, escape groove is prevented
Only pressing mold collides with water side, and forming tank makes collar form inside groove with the resistance ring on nipple.
Preferably, limited post includes supplying the fire-fighting joint miner diameter end being arranged and the bigger diameter end abutted with water side end face,
Bigger diameter end diameter is more than miner diameter end diameter and is located at close to body side.
By using above-mentioned technical proposal, miner diameter end outer wall is radially fixed by fire-fighting joint, and bigger diameter end is by fire-fighting joint
Axial restraint, so as to which fire-fighting joint be positioned, it is easy to determine the relative position relation between fire-fighting joint and pressing mold, beneficial to collar
Rapidly, quickly it is wrapped on fire-fighting joint.
Preferably, press mold is provided with close to the side of forming tank the pressurized tank for extruding reinforcing ring in escape groove.
By using above-mentioned technical proposal, fire-fighting joint is set on limited post, pressurized tank is relative with annular groove
Should, reinforcing ring is set in pressurized tank, reinforcing ring is further closed up, so as to be set in annular groove.
Preferably, compacting portion of one of press mold formed with insertion breach.
By using above-mentioned technical proposal, the part that compacting portion closes up reinforcing ring is pressed further into breach, so as to enter
One step closes up reinforcing ring, ensures that reinforcing ring is completely embedded with fire-fighting joint.
Preferably, limiting section forms chamfering structure away from body one end.
By using above-mentioned technical proposal, chamfering structure has been easy to fire-fighting joint being set on limited post.
Preferably, crushing block shares eight.
By using above-mentioned technical proposal, eight crushing blocks exert a force jointly, drive collar imposed deformation so that collar is becoming
Homogeneous deformation during change, reduce the possibility of collar rupture.
In summary, the utility model has the advantages that：Limited post positions fire-fighting joint completely, and press mold squeezes
Pressure beam covers and reinforcing ring, them is set in fire-fighting joint and upper, ensures that fire-fighting joint is smoothly installed.
