Hot workpiece fast transfer quenching system

Abstract

The invention relates to a hot workpiece fast transfer quenching system which comprises a cooling tank and at least one thermal treatment furnace, wherein the cooling tank and the thermal treatment furnaces are arranged in a split type. Each thermal treatment furnace is provided with a furnace door which can be opened or closed. A material box containing hot workpieces is arranged in each thermal treatment furnace. The hot workpiece fast transfer quenching system is characterized in that a transfer device is arranged between the cooling tank and each thermal treatment furnace and used for transferring the material box in the corresponding thermal treatment furnace into the cooling tank; the whole cooling tank is rectangular, and a water sink, an oil sink and a rinse tank are arranged inside the cooling tank side by side at intervals; and each transfer device is mounted at the upper edge of the cooling tank and reciprocates in the longitudinal direction to take in the material box of the corresponding thermal treatment furnace. By means of the transfer devices, the multiple thermal treatment furnaces are matched with the same cooling tank, the transfer time of the hot workpieces between a thermal treatment process and a cooling process is reasonably utilized, continuous quenching treatment can be conducted on the different hot workpieces, the work efficiency is improved, and energy consumption is lowered.

Description

technical field [0001] The invention relates to the technical field of heat treatment, in particular to a rapid transfer quenching system for hot workpieces. Background technique [0002] Recently, the traditional way is to take out the hot workpiece after heat treatment from the heat treatment furnace by forklift or spreader, and transfer it to the cooling tank for cooling and cooling to complete the quenching process. The heat treatment process and the cooling process are set independently, and the The work efficiency is low, and the transfer time of the hot workpiece between the two processes is long, and the temperature difference of the hot workpiece is too large. Because the quenching process has strict requirements on the temperature of the hot workpiece, under such time conditions, the hot workpiece is delayed when it is released from the furnace. The best quenching process time, affecting the quality of hot workpiece. To solve this problem, the existing treatment m...

Problems solved by technology

[0004] Although the above technical solution reduces the time wasted due to waiting and repeated start-up actions by rationally utilizing the cooperation of various mechanism components, so as to avoid delaying the optimal quenching time of the workpiece, there are still some shortcomings. Transfer from the heat treatment furnace to the quenching chamber to realize the continuity of the workpiece in the lateral direction. Its structure is complex, and it is difficult to maintain the consistency between the roller tables. The quenching mechanism is only suitable for the quenching treatment of the same kind of workpiece. Its structure Single, narrow scope of application, low efficiency
