Description

Quenching device for high-strength steel grating Technical Field The utility model relates to the field of metal heat treatment, in particular to a high-strength steel grating quenching device. Background The steel grating is a steel product which is formed by intersecting flat steel with transverse rods according to a certain interval and welding square lattices in the middle, and is mainly used for making ditch cover plates, steel structure platform plates, tread plates of steel ladders and the like, and the transverse rods are generally made of twisted square steel. Quenching the steel sheet can improve the rigidity, hardness, wear resistance, fatigue strength and toughness of the steel. A steel grating spray quenching device is mentioned in the prior China publication (issued publication number: CN 215560470U). Including the workstation, it is connected with two-way threaded rod to rotate on the workstation, is equipped with drive two-way threaded rod pivoted driving piece on the workstation, is equipped with the guide bar on the workstation, and two equal threaded connection of the shaft that two-way threaded rod both ends screw is opposite has a spray board, and the guide bar runs through two spray boards simultaneously, is equipped with the shower on the spray board, and the shower on two spray boards sets up relatively, and shower one end seals the setting, and the other end intercommunication water supply assembly, has seted up a plurality of spray holes on the shower, and the spray hole is towards the steel grating setting of waiting to quench. The application has the effect of improving the working efficiency. When the existing device quenches the steel grating, the steel grating is required to be placed between the spray pipes, then the quenching liquid sprayed to the middle steel grating by the spray pipes at the two sides quenches the steel grating, but the existing device can only slightly adjust the distance between the steel grating and the spray pipes at the two sides in the quenching process, so that the horizontal landing position of the quenching liquid on the steel plate can only be slightly changed by gravity, the corner where the quenching liquid is difficult to spray originally is difficult to spray by the spray pipe distance change to obtain the spraying of the quenching liquid, the sprayed quenching liquid is difficult to collect and waste, and the recycling is unfavorable.
