Temperature control sorting device used in pipe machining process

Abstract

The invention relates to a temperature control sorting device used in the pipe machining process. The temperature control sorting device comprises an automatic feeding device, an intermediate frequency heating furnace, a sorting device and a control cabinet. The automatic feeding device is connected with a feeding inlet of the intermediate frequency heating furnace through a conveying mechanism. The sorting device is connected with a discharging outlet of the intermediate frequency heating furnace. The control cabinet is connected with the sorting device. The automatic feeding device is composed of a fixed plate and a plurality of ejector plates. A baffle with the two ends being connected with the two side faces of a hopper is fixedly arranged between each two ejector plates. The ejector surface of each ejector plate is tilted relative to a discharging outlet of the hopper. The ejector plates are driven by an ejector air cylinder to move up and down, and thus materials on the ejector surfaces inside the hopper are driven to cross the corresponding baffles under the effect of gravity to fall into the conveying mechanism in sequence. The sorting device comprises a temperature sensor. The control cabinet controls the sorting device by receiving a workpiece temperature detected by the temperature sensor so as to sort workpieces at the discharging outlet of the intermediate frequency heating furnace. The temperature control sorting device is simple in structure and capable of automatically achieving efficient and precise sorting.

Description

technical field

[0001] The invention relates to the field of intermediate frequency furnaces, in particular to a temperature-controlled material selection device in the pipe processing process. Background technique

[0002] Intermediate frequency furnace It is a power supply device that converts power frequency 50HZ AC power into intermediate frequency (above 300HZ to 1000HZ). It converts three-phase power frequency AC power into DC power after rectification, and then converts DC power into adjustable medium frequency current, which is supplied by capacitors and sensors. The medium-frequency alternating current flowing in the coil generates high-density magnetic force lines in the induction coil, and cuts the metal material contained in the induction coil, generates a large eddy current in the metal material, and uses the principle of electromagnetic induction to heat the metal. Due to the fast heating speed of the intermediate frequency furnace, high production efficiency ...
