Abstract

The invention discloses a secondary quenching treatment device and a rod-shaped workpiece processing method. The quenching treatment device comprises a primary induction heater assembly, a primary quenching assembly, a secondary induction heater assembly, a secondary quenching assembly and a transmission mechanism. In the process of processing and treating an automobile anti-collision rod, the rod-shaped workpiece can sequentially pass through the primary induction heater assembly, the primary quenching assembly, the secondary induction heater assembly and the secondary quenching assembly through the transmission mechanism, so that different heat treatments can be respectively carried out on the core layer and the surface layer of the rod-shaped workpiece section by section on the same production line to improve the comprehensive mechanical properties of the rod-shaped workpiece; and the transmission mechanism is simple in structure, convenient to assemble and efficient and stable in transmission, so that the rod-shaped workpiece can spin while advancing in the length direction of the rod-shaped workpiece and can be evenly heated and quenched while being processed and treated, andthe heat treatment quality of products can be improved.

Description

technical field [0001] The invention relates to the technical field of quenching devices, in particular to a secondary rapid cooling and quenching treatment device and a processing method for rod-shaped workpieces. Background technique [0002] Quenching is to heat the steel above the critical temperature, hold it for a certain period of time, and then cool it at a rate greater than the critical cooling rate, so as to obtain an unbalanced structure mainly composed of martensite (and also obtain bainite or maintain single-phase austenite according to needs). ) of a heat treatment process. Quenching is the most widely used process method in steel heat treatment process. The purpose of quenching is to transform supercooled austenite into martensite or bainite to obtain martensite or bainite structure, and then cooperate with different temperature Tempering to greatly improve the rigidity, hardness, wear resistance, fatigue strength and toughness of steel, so as to meet the dif...
