What is induction furnace three sorting equipment?
1. Induction electric furnace The three-sorting equipment measures the temperature of the blanks coming out of the discharge port of the intermediate frequency electric furnace through the infrared thermometer, and feeds this temperature signal to the intermediate frequency furnace control system and the PLC control system through the temperature control system, so as to Adjust the heating temperature and control the temperature to classify the cylinder to achieve the qualified process requirements. The blank heating temperature passes, the blank heating temperature lower than the process requirements and the blank heating temperature higher than the process requirements enter the low temperature material frame and the high temperature material frame respectively, to realize the induction furnace three-sorting .
- The automatic sorting mechanism of the induction furnace three sorting equipment consists of photoelectric switch, infrared temperature detector, regulator (SR3) and PLC. After the photoelectric switch detects the discharge, it sends this signal to the PLC. After the PLC detects the discharge signal, it sends out an instruction to detect whether there is an upper and lower limit alarm signal of the regulator. If there is this signal, it will issue an instruction to make the unqualified pusher cylinder move; if there is no such signal, it will issue an instruction to make the qualified pusher cylinder move. The qualified or unqualified command signal here is a delayed signal sent after the discharge signal is detected, the purpose is to avoid the sorting cylinder caused by the instability of the infrared temperature detector and the regulator in the initial stage of temperature measurement erroneous action. The length of the delay time is adjusted by the analog setting potentiometer 0 on the PLC (the setting range of this potentiometer is 0—20 seconds). Whether the workpiece temperature is qualified or not is completed by the regulator (SR3), and the upper and lower limits of the qualified temperature range should be set as the upper and lower limit alarms of the regulator. For example: If the workpiece temperature is considered normal in the range of 1100°C—1200°C, the upper limit alarm of the regulator should be set to 1200°C, and the lower limit alarm should be set to 1100°C. The workpieces within this temperature range are pushed into the qualified workpiece guide rail by the qualified pusher cylinder, and the workpieces not within this temperature range are pushed into the unqualified workpiece guideway by the unqualified pusher cylinder, so as to complete the automatic sorting of the intermediate frequency furnace pushing and discharging. .
