The present invention can also adopt following technical measures:
Described live roll has a back shaft, the axle center of back shaft is shaped on through hole, the through hole two ends of back shaft are equipped with the tube stub that connects water-cooled tube, be shaped on four keyways on the back shaft, on back shaft, be spaced a plurality of running rollers and the both sides guide deflection sheaves that have four coupling keys in porose are installed, between each running roller and the guide deflection sheave collet is installed, is filled with insulating cotton between each collet and the back shaft, on back shaft, be separately installed with the retaining ring and the steady brace of both sides guide deflection sheave.
Described back shaft is made by No. 45 steel, and described running roller, guide deflection sheave and collet are made by heat-resisting steels.
Advantage and positively effect that the present invention has are: because the live roll of step-down gear, chain and chain wheel drive is installed in process furnace, the discharging track of process furnace and the charging track of hydropress are installed between process furnace and hydropress, make like this workpiece in the process furnace by the live roll automatic transport to the hydropress quenching of finalizing the design, install respectively at process furnace import and hydropress discharge end and to have the charging track that promotes cylinder and to have the discharging track that spurs cylinder, thereby realize heat treated automated operation.In addition, the hydro-cylinder up and down of hydropress is on driving in lower table clamping mold, the spray cooling oil, hydro-cylinder is also done synchronous up and down motion repeatedly (swing) up and down, increased the oil cooling ability, improved the quenching quality, live roll in the process furnace adopts hollow support axle and structures such as running roller, collet in addition, not only saved heat-resisting steels, and reduce cost, by the cooling of water to back shaft, prolong its work-ing life, it is stable that the present invention also has quenching hardness in addition, the technology favorable reproducibility, advantage of high production efficiency.
