The invention discloses a continuous
quenching device for jacking a chain wheel workpiece. The continuous
quenching device for jacking the chain wheel workpiece comprises a feeding motor, a feeding
caterpillar band, a feeding roller, a feeding area, a
heating furnace area, a cooling groove, a
quenching groove and a discharging hoisting part arranged in the quenching groove; the quenching groove isadjacent to the outlet side of the
heating furnace area; the feeding motor drives a feeding transmission part to drive the feeding
caterpillar band to continuously march to cyclically pass through the feeding area, the
heating furnace area and the cooling groove; a discharging motor drives a discharging roller to drive a discharging
caterpillar band to continuously march to conveying the workpiece to be discharged; the inlet side of the heating furnace area is provided with a
methanol first spraying port, and after ignition, a fire curtain scouring the whole inlet side can be formed; and theside, where the feeding caterpillar band moves out of the cooling groove, on the cooling groove is provided with a
methanol second spraying port, and after ignition, it is used for
drying the feedingcaterpillar band under high temperature. After the scheme is adopted, production is efficient, the formed fire curtain prevents
oxygen-containing air from entering the heating furnace area, it is avoided that
oxygen-containing
water vapor enters the heating furnace area along with the feeding caterpillar band, and therefore oxidization of the workpiece in a furnace is effectively avoided.
