Embodiment 1

[0058] to combine Figure 1 to Figure 4 As shown, the induction hardening equipment provided in the first embodiment includes a workpiece platform 1 and a quenching induction device 2 . Wherein, the workpiece platform 1 is used to install the workpiece 4 to be processed, and the quenching induction device 2 includes an inductor bracket 21 and a plurality of quenching heating inductors 22 arranged on the inductor bracket 21, and a plurality of quenching heating inductors 22 are used to enclose It is used in the working area where the workpiece 4 is heated as a whole. The shape and size of this working area can be flexibly set depending on the condition of the workpiece 4. For example, when the workpiece 4 is in the shape of a ring, the shape of the working area also corresponds to a ring-shaped area, so that the workpiece 4 is heated more evenly. It can be seen that the induction hardening equipment adopts the overall heating and quenching method. Compared with the existing sc...

Embodiment 2

[0082] Embodiment 2 provides a heat treatment system, which includes a cooling pool and the induction hardening equipment in Embodiment 1; wherein, the cooling pool is used to cool the workpiece 4 heated by the induction hardening equipment, and the cooling pool can be a preset pool body , add quenching liquid in the pool body. The induction hardening equipment is correspondingly arranged above the cooling pool, and the heated workpiece 4 can be put into the cooling pool as a whole for cooling.

[0083] The heat treatment system can realize the quenching treatment of the slewing bearing. Combine below Figure 1 to Figure 4Be specific. The induction hardening equipment includes a workpiece platform 1 and a quenching induction device 2 . Wherein, the workpiece platform 1 is arranged in the cooling pool, and the workpiece platform 1 is used to install the slewing support to be processed, and can drive the slewing support to perform lifting and rotating movements. The quenchin...

Abstract

The invention discloses an induction quenching device. The induction quenching device comprises a workpiece platform and a quenching induction device. The workpiece platform is used for installing a workpiece to be machined. The quenching induction device comprises an inductor support and a plurality of quenching heating inductors arranged on the inductor support. A work area used for conducting overall heating on the workpiece is defined by the multiple quenching heating inductors, and the whole workpiece is evenly heated. Compared with existing scanning type induction heating quenching, the problem of quenching soft bands of the workpeice to be machined is effectively solved in an integral quenching manner. Meanwhile, the induction quenching device can quench workpieces of different sizes, and the application range is wider.

Description

technical field [0001] The invention relates to the technical field of heat treatment equipment, in particular to induction hardening equipment and a heat treatment system. Background technique [0002] Large transmission parts such as slewing bearings are widely used in concrete pump trucks, wind power generation equipment, port equipment, and crane equipment. The most commonly used slewing bearing structure is composed of inner and outer rings and steel balls or rollers. In order to improve the bearing capacity and service life of the slewing ring, the inner and outer rings must be quenched. The most commonly used quenching methods at this stage are mainly high-temperature furnace quenching and induction hardening, which are widely used because of the fast quenching speed of workpieces. At present, induction hardening equipment at home and abroad mainly adopts scanning induction heating and quenching in which the sensor and the workpiece move relative to each other, and ...
