Horizontal high-frequency quenching machine

Abstract

The invention discloses a horizontal high-frequency quenching machine which comprises a base, a high-frequency quenching heating device, cooling liquid, a cooling oil tank, a stepping feeding device, a pushing transmission device used during workpiece quenching, a workpiece turning-over device horizontally arranged during workpiece quenching and a program control system. The high-frequency quenching heating device comprises a high-frequency power supply control cabinet and an induction coil which is in circuit connection with a high-frequency power supply. The stepping feeding device is longitudinally arranged in front of a working platform of the base in a front-and-back mode, and vertical columns are respectively arranged on the left side and the right side of the rear portion of the working platform. The workpiece turning-over device is transversely arranged in a left-and-right mode, an inlet of the stepping feeding device is connected with a hopper, and an outlet of the stepping feeding device is positioned above the workpiece turning-over device. The induction coil is positioned on the workpiece turning-over device side, and the pushing transmission device is arranged on the vertical columns. The horizontal high-frequency quenching machine has the advantages of being high in machining precise, good in repetition, and capable of reducing deformation of shaft parts during high-frequency quenching, performing automatic production and reducing labor intensity of workers.

Description

technical field [0001] The invention relates to the technical field of quenching equipment, in particular to a horizontal high-frequency quenching machine. Background technique [0002] Quenching process is widely used in modern machinery manufacturing industry. The important parts in machinery, especially the steel parts used in automobiles, airplanes and rockets, are almost all quenched. In order to meet the technical requirements of various parts, various quenching processes have been developed. For example, according to the part to be treated, there are overall, local quenching and surface quenching; according to whether the phase transformation is complete during heating, there are complete quenching and incomplete quenching (for hypoeutectoid steel, this method is also called subcritical quenching); according to cooling The content of time phase transformation includes graded quenching, austempering and underspeed quenching. [0003] For the quenching treatment of s...

Problems solved by technology

[0003] For the quenching treatment of shaft parts, the existing heat treatment factory uses simple heat treatment equipment, by setting two thimbles to fix the shaft, and then heat-treating it with high-frequency coils. The stress of the thimble is easy to be deformed under high temperature, which affects the accuracy and reduces the quality of the product
