[0002] When alloy parts are processed, high temperature heating is required. After the alloy parts are heated, quenching treatment is completed. In order to obtain better comprehensive performance, the existing quenching heat treatment process usually adopts salt bath quenching process. The existing salt bath quenching tooling generally adopts a grid-type material tray, and the roller is placed vertically in the material tray. Although this tooling has a simple structure, the material cannot be quenched during quenching, and quenching dead corners are easily generated on the material.

[0003] According to a salt bath quenching tool disclosed in the existing patent document with publication number CN218561516U, it includes a tray rack and a tray frame arranged on the tray rack; the tray frame includes a frame body and a support bar 1, the frame body is provided with a plurality of placement grooves, and the two ends of the support bar 1 are arranged in the placement grooves on both sides of the frame body, so that multiple support bars 1 are arranged in parallel; the support bar 1 is provided with a recessed section for limiting the workpiece to be quenched. When in use, this technical solution has a support block nested inside the spacer sleeve, and the support block is limited by the open groove of the spacer sleeve to prevent the tray frame from changing its position due to the rotation of the spacer sleeve or the support block during the quenching process. With respect to the above technical solution, although this solution avoids shaking when in use, the materials cannot move, so that the materials cannot be fully quenched, which is inconvenient when in use.

[0005] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical scheme: a salt bath quenching device for high-temperature alloy parts, including a quenching device body, the quenching device body includes a quenching box, a fixed seat is fixedly installed on the side of the quenching box, a lifting mechanism is fixedly installed on the fixed seat, a fixed frame is fixedly installed on the top of the lifting mechanism, the fixed frame cooperates with the top of the quenching box, a cavity is opened inside the quenching box, a support plate is movably installed inside the cavity, and both ends of the support plate are fixedly installed on the fixed frame.

[0006] Furthermore, the support plate is provided with a slot, and a fixing rod is movably installed inside the slot.

[0012] 1. A salt bath quenching device for high-temperature alloy parts. When in use, the support plate moves up and down to make the material match the top of the fixed rod. The fixed rod pushes the material to the side to change the position of the material, thereby completing the mobile quenching of the material and ensuring the comprehensive quenching of the material.
