Integrated immersion quenching device of steel bottle quenching-and-tempering line

Abstract

The invention discloses an integrated immersion quenching device of a steel bottle quenching-and-tempering line, comprising a main rack, a quenching rack provided with a steel bottle holding mechanism and a quenching groove containing a quenching liquid. Each side of the quenching rack is provided with a quenching rack roller. The main rack is provided with a first guide rail matched with the quenching rack roller. The quenching rack is fixedly connected with a hydraulic cylinder. The front end of a hydraulic push rod matched with the hydraulic cylinder is fixed on the main rack. The main rack is further provided with a sprocket assembly. One end of a chain matched with the sprocket assembly is fixedly connected with the top of the quenching rack, while the other end of the chain is fixedly connected with a balancing weight. The quenching groove comprises a primary quenching groove and a secondary quenching groove between which a circulation pump is arranged. The circulation pump is respectively connected with the primary quenching groove and the secondary quenching groove through a two-way pipeline. The invention has the benefits of simple structure, stable operation, rapid immersion of the quenching rack into the quenching liquid, improved quenching intensity, increased balancing weight and reduced driving burden of the hydraulic cylinder.

Description

technical field [0001] The invention relates to a steel cylinder quenching and tempering equipment, in particular to an integral immersion quenching device applied to a steel cylinder quenching and tempering production line. Background technique [0002] Quenching treatment is required in the steel cylinder quenching and tempering production process. The existing steel cylinder quenching and tempering production line generally sends the steel cylinder into the quenching tank filled with quenching liquid through chains and other conveying mechanisms. The intensity is not enough. In order to ensure the straightness of the steel cylinder, it is best to immerse the steel cylinder in the quenching liquid for quenching. Therefore, the quenching frame needs to be equipped with a lifting device, which not only ensures that the steel cylinder is quickly immersed in the quenching liquid, but also ensures that the quenching frame is relative to the main frame. The operation is stable. ...

[0002] Quenching treatment is required in the steel cylinder quenching and tempering production process. The existing steel cylinder quenching and tempering production line generally sends the steel cylinder into the quenching tank filled with quenching liquid through chains and other conveying mechanisms. The intensity is not enough. In order to ensure the straightness of the steel cylinder, it is best to immerse the steel cylinder in the quenching liquid for quenching. Therefore, the quenching frame needs to be equipped with a lifting device, which not only ensures that the steel cylinder is quickly immersed in the quenching liquid, but also ensures that the quenching frame is relative to the main frame. The operation is stable. Since the quenching frame and steel cylinders may weigh tens of tons, coupled with the uneven distribution of the overall weight, misalignment during movement, and buoyancy changes when immersed in liquid, the overall stability factors are uncertain, so the lifting device is in the process of lifting. Stability is particularly important, and the quenching mechanism on the existing steel cylinder quenching and tempering production lin
