Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of quenching quality control, in particular to a carbonitriding quenching quality control device for thin-walled parts. Background Art
[0002] Carbonitriding is a method of simultaneously carburizing and nitriding the surface of a workpiece. After nitriding, quenching treatment is required. Thin-walled parts also need to be quenched after carbonitriding to achieve a higher hardness of the thin-walled parts.
[0003] However, the existing quenching equipment cannot control the cooling time of thin-walled parts, and cannot use different methods to cool thin-walled parts. Quenching thin-walled parts to increase their hardness will produce higher stress, which is prone to deformation, cracks and other problems. For this reason, we propose a thin-walled parts carbonitriding quenching quality control device. Utility Model Content

[0013] Furthermore, an auxiliary rod is fixed inside the structural frame on one side of the screw rod by bolts, and the auxiliary rod passes through the internal thread slider.
[0014] Compared with the prior art, the beneficial effects of the utility model are:
[0015] The servo motor drives the screw rod to rotate, and the rotation of the screw rod pushes the internal thread slider to move downward.
