Problems solved by technology

In this way, it is not easy to guarantee the dimensional accuracy, and the processing error is generally around ±0.20mm
Such a large error can only be adjusted by adding shims when the reel is assembled, which has an impact on the accuracy and quality of the quadrangular pyramid sleeve or reel

Abstract

The invention discloses a method for finely machining a pyramid cover of a drum part of a metallurgical machine, which finely machines a roughly machined workpiece by the following steps: 1, mounting the workpiece on a dividing apparatus and mounting the dividing apparatus provided with the workpiece on a worktable of a machine tool, wherein the workpiece and the dividing apparatus are in gaplessrigid connection; 2, milling pyramids distributed along the direction of a group of buses on the top face of the workpiece; 3, milling the inclined working planes of the pyramids distributed along the direction of another group of buses of the workpiece; 4, milling the inclined working planes of all pyramids of the workpiece; and 5, polishing the inclined working planes of each pyramid. When the method is used for finely machining the pyramid cover, the angular dimensions of the inclined working planes of the pyramids are guaranteed accurately; the inclined working planes of the pyramids in the same circle are fully symmetric about the center of the inner hole of the pyramid cover in distance, angle and dimension; and the required precision of each inclined working plane of the pyramid cover is ensured.

Description

technical field [0001] The invention relates to a processing method for metallurgical machinery reel parts, in particular to a finishing method for pyramid sleeves of metallurgical machinery reel parts. Background technique [0002] The reel is the main part of the uncoiler and coiler equipment in metallurgical machinery, and the square pyramid sleeve is the core part of the reel. The structure of the rough-processed quadrangular pyramid sleeve is as follows: figure 1 , figure 2 As shown, a plurality of pyramids 10 are arranged on the surface of the square pyramid sleeve, and each pyramid is arranged longitudinally along the square pyramid sleeve, and at the same time, it is uniformly distributed around the rotation axis of the square pyramid sleeve. figure 1 , figure 2 Four groups of pyramids are evenly distributed on the circumference of the shown quadrangular pyramid sleeve, and each group of pyramids includes 2 pyramids that are symmetrical to each other, that is, 8...
