Abstract

The invention belongs to the technical field of steel heat treatment, and particularly relates to an arc-shaped cutting board multi-row continuous quenching device which comprises a rack system, a roller way conveying system and a water spraying system. The rack system comprises a fixed rack located on the outermost side of the quenching device and a movable rack connected to the interior of the fixed rack in a lifting mode. The roller way conveying system comprises a plurality of curved surface roller ways which are oppositely arranged on the movable rack and the fixed rack, and a cutting board passage for an arc-shaped cutting board to pass through is formed between the oppositely arranged curved surface roller ways; the water spraying system comprises a plurality of slit nozzles and round hole nozzles which are oppositely arranged on the movable rack and the fixed rack; and the curved surface roller way, the slit nozzle and the circular hole nozzle which are arranged on the movable rack are connected with the movable rack in a follow-up manner. The cutting board is continuously quenched during movement, quenching soft points are eliminated, and cooling efficiency, cooling uniformity and cutting board surface quality are considered; quenching deformation of the cutting board is restrained through the curved surface roller way, and the straightness of the quenched cutting board is improved.

Description

technical field [0001] The invention belongs to the technical field of steel heat treatment, and in particular relates to a multi-row continuous quenching device with arc-shaped knife plates. Background technique [0002] The curved knife plate is a wear-resistant part used in construction machinery and mining machinery, and it is used in high-wear service conditions. The material used for this type of blade is low-alloy wear-resistant steel. In addition to requiring high strength and hardness, the material also needs to have high toughness, easy forming, and easy welding. Therefore, quenching is usually required to obtain a high-hardness martensite matrix structure. [0003] Domestic arc knife plate quenching generally adopts immersion quenching or pressure quenching. When immersion quenching is used, multiple groups of arc-shaped blades are fixed in the clamping mechanism, and sent to the water tank by a special spreader for quenching, and the cooling water in the pool / t...
