A Method of Improving the Machining Accuracy of Tension Coiler Reel

Abstract

The invention relates to a method for processing tension coiler rolls. It solves the shortcomings of the traditional processing method such as poor coaxiality, difficult installation, large radial runout of the outer support journal of the shaft end of the reel, and large radial runout of the reel body, and difficulty in ensuring the processing accuracy of the reel. Measures: A method to improve the processing accuracy of the reel of the tension coiler: the outer circular surface of the blank sector plate, the hollow shaft of the blank and the pyramidal shaft of the blank after heat treatment are respectively processed to the positions where the gears and bearings are installed to the set value. 2-5 mm surplus, the other parts and the hook head plate and positioning plate of the reel are respectively processed to the set value; the inclined table surface in contact with the fan-shaped plate and the pyramid shaft is ground to fit; the reel parts after assembly are processed , and use a dial indicator to detect the radial runout of the surplus part; use a heavy-duty machine tool to process it to the set value; check the reel. The invention greatly reduces the ellipticity and radial runout of the hollow shaft, the pyramid shaft, and the mandrel shaft of the reel, and improves the coiling speed and coil quality.

Description

Technical field [0001] The invention involves a mechanical processing method, which is specific to the method of processing tension rolls. Background technique [0002] The tension roll machine is an important equipment on the production line of cold -rolled and hot -rolled steel. It plays a role in supporting or collecting steel and regulating rolling tension.The roll is the core component. It consists of hollow axis, edge cone axis, fan -shaped plate, hook head plate, positioning plate, external support head, rotating swell -contracted cylinder and other components.The manufacturing accuracy of the rolling tube has a direct impact on the quality of the steel products. The accuracy of the rolling tube is high, the tension of the tens of steel rolling is small, the unit is running smoothly, the quality of the steel inner part of the steel roll is small, and the rolling product is high.Conversely, the accuracy of the rolling cylinder is low, the ellipse is large, and the axis end ...

Problems solved by technology

However, due to the influence of the processing and assembly accuracy of the hollow shaft, pyramid shaft, and fan-shaped plate, the bearings and gears installed on the hollow shaft, the outer circular surface of the reel mandrel composed of the pyramid shaft and the fan-shaped plate, and the pyramid shaft It is very difficult to install the outer support bearing on the coaxial line, resulting in radial runout of the outer support journal at the shaft end of the reel, and large ellipticity and radial runout of the reel body, which makes it difficult to guarantee the machining accuracy of the reel And affect product quality and pass rate
