Pressure quenching and tempering integrated machine tool for thin-wall annular parts

Abstract

The invention relates to a press quenching machine tool, in particular to an integrated press quenching and tempering machine tool for thin-walled annular parts; Fire machine tool, the machine tool can realize the effect of small wear of the parts on the mandrel, perfect waterproof measures, and automatic loading and unloading; the machine tool includes upper mold, lower mold, upper mold lifting assembly, liquid spray ring, liquid spray ring slider, return The fire heating sensor and the liquid spray ring lifting assembly, etc.; the lower mold, the upper mold lifting assembly and the liquid spray ring lifting assembly are all installed on the frame, the liquid spray ring slider is connected with the liquid spray ring lifting assembly, and the liquid spray ring slider A liquid spray ring and a tempering heating sensor are installed on it; the present invention overcomes the shortcomings of the existing machine tool that the shape-limited mandrel is severely worn after the parts are quenched, and the quenching and tempering must be processed separately, and achieves integrated heating and quenching. Integrate with the tempering process, the wear of the mandrel is small, and the effect of automatic loading and unloading is perfect with waterproof measures.

Description

technical field [0001] The invention relates to a press-quenching machine tool, in particular to an integrated press-quenching-tempering machine tool for thin-walled annular parts. Background technique [0002] Quenching distortion is the most common problem in the heat treatment process. For mass-produced parts, controlling quenching distortion is an effective means to improve the internal quality and service life of the product. The use of molded quenching technology is a direct and effective measure to prevent quenching distortion and improve the pass rate. Distortion trend, modify the structure and shape of the shape-limited mold, apply it to the quenching system, and finally realize that different types of press quenching machine tools can meet the requirements of the minimum quenching distortion and the highest quenching quality for different products. [0003] In order to reduce the quenching distortion of thin-walled annular parts during press quenching, it is necess...

AI Technical Summary

Problems solved by technology

[0007] In order to overcome the serious wear and tear on the shape-limited mandrel of the existing mold press quenching machine tool after the quenching of the thin-walled annular parts, the maintenance cost of the mandrel is relatively high; quenching and tempering are processed by different machine tools, which lengthens the process flow and reduces storage and transportation costs Increased shortcomings, the technical problem to be solved by the present invention is to provide a press quenching and tempering machine tool integrating heating, quenching and tempering processes. The expansion of the ring parts offsets the shrinkage of the thin-walled ring parts after quenching, thereby reducing the holding force of the thin-walled ring parts to the mandrel, so that the wear of the thin-walled ring parts to the mandrel is small; the parts are quenched and tempered in one machine Finished on the machine tool, which can improve processing efficiency and reduce storage and transportation costs
