Abstract

According to the plastic steel air duct flange machining device and method, a first servo motor of a fixing assembly of the device controls an annular workpiece to rotate and move through a main shaft speed reducer and a rapid chuck; a third servo motor of the clamping assembly controls a lead screw worm gear to rotate through a third planetary reducer, controls a pressing lead screw to push or pull a sliding block and controls the clamping distance between a sliding roller and a fixed bottom roller. A second servo motor of the overturning assembly controls a rotating gear to crawl along a gear ring through a second planetary reducer, drives a main fixing table to rotate around a center fixing shaft through a second fixing support and enables a sliding roller and a fixed bottom roller to rotate to drive a clamping part, clamped between the sliding roller and the fixed bottom roller, of the extruded and extended workpiece to overturn, and workpiece flanging is completed. According to the flanging device, heating is not needed in the flanging process, a machined air duct flange is high in precision, the radian formed by flanging is consistent, the end face of the flange is flat, stress concentration of a bent part can be effectively avoided, and the flanging quality is high.

Description

technical field [0001] The invention belongs to the technical field of air duct flange manufacturing, and in particular relates to a plastic-steel air duct flange processing device and a processing method. Background technique [0002] The properties of plastic-steel ducts such as rigidity, elasticity, corrosion resistance, and anti-aging properties are excellent. They are used to form plastic-steel air ducts in ventilation scenarios. They have a long service life and are favored by the market. To meet the needs of the usage scenario, the end of the air duct needs to be processed to form a flange, and the adjacent air ducts are connected and fixed through the flange. At present, the commonly used plastic-steel air duct flanging process is common mechanical flanging equipment. The end of the air duct is flanged through a flanging die, which often needs to be heated and rotated to facilitate the formation of flanging. During flanging processing, usually both the flanging die ...
