Electric self-heating quenching device

Abstract

The invention belongs to the technical field of quenching devices, and particularly relates to an electric self-heating quenching device. The electric self-heating quenching device includes a shell, aconnecting column, a limiting plate, a fixing pipe, an electric pushing rod, a fixing plate, a motor, a rotating seat, a baffle, a limiting rod, a first partition plate, a groove, a reflux box, a cooling pipe, a first water pump, a water inlet pipe, a reflux pipe, a water tank, a filter net, a second water pump, a water outlet pipe, a communicating pipe, a sprayer, a second partition plate, heatdissipation fins, a fan and a steam cavity. According to the electric self-heating quenching device, steam inside the shell is sucked into the steam cavity through the fan, the high-temperature steamis cooled through the heat dissipation fins, thus the high-temperature steam is condensed into water to fall into the top of the second partition plate, and the condensed water flows into the reflux box through the reflux pipe; the water is collected through the groove in the top of the first partition plate, is cooled through the cooling pipe and flows back into the reflux box; and the cooled water is reintroduced into the water tank from the water inlet pipe through the first water pump, impurities in the water are filtered through the filter net inside the water tank, and the water is recycled.

Description

technical field [0001] The invention belongs to the technical field of quenching devices, in particular to an electric self-heating quenching device. Background technique [0002] The quenching of steel is to heat the steel to a temperature above the critical temperature Ac3 (hypoeutectoid steel) or Ac1 (hypereutectoid steel), keep it warm for a period of time to make it fully or partially austenitized, and then cool it at a temperature greater than the critical cooling rate. Rapid cooling to below Ms (or near Ms isothermal) heat treatment process for martensite (or bainite) transformation, usually also solid solution treatment of aluminum alloy, copper alloy, titanium alloy, tempered glass and other materials or with The heat treatment process of rapid cooling process is called quenching.

AI Technical Summary

Problems solved by technology

[0003] At present, the existing tubular workpieces use vertical heating furnaces. For shorter workpieces, the vertical heating furnace wastes a lot of energy for heating and heat preservation. If a small vertical heating furnace is used, once a long workpiece is encountered, it cannot be loaded. It cannot quench tubular workpieces of different lengths well, and during the quenching process, a large amount of high-temperature water vapor will be generated, which is easy to cause injury to the operator, and generally cooling requires a large amount of water. The recycling of cooling water in the device is poor, and it is easy to waste a lot of water in the process of quenching, which is not conducive to water saving and environmental protection
