1results about How to "Fully tempered" patented technology

This invention relates to the field of heat treatment technology for mechanical castings, specifically to a heat treatment equipment and method for engineering machinery parts. A motor-driven turntable is installed in the pretreatment chamber. A bearing-mounted sleeve is installed at the other end of the inner cavity of the pretreatment chamber. Four sets of positioning tubes are arranged in a circumferential array on the turntable. One end of the sleeve faces the turntable, and a rod is slidably inserted into the sleeve. A telescopic pressure plate is installed at the other end of the rod, and the telescopic pressure plate is sleeved on the positioning tube. The workpiece is clamped between the telescopic pressure plate and the turntable. The beneficial effects are: by setting up a pretreatment device before tempering, the quenching residue generated is fully centrifuged and separated through centrifugal rotation. Then, the heat is recovered from the tempering furnace to form high-temperature gas. Under the scouring of the high-temperature gas, not only can the surface quenching coolant be vaporized, but the workpiece is also preheated, achieving a thorough tempering process.
