Embodiment Construction

[0053] The method for finishing the pyramid sleeve of the metallurgical machinery reel part of the present invention adopts an indexing device to index each pyramid body distributed on the circumference of the pyramid sleeve.

[0054] The indexing device used in the present invention is such as Figure 4 As shown, it includes a frame 31, a mandrel 32, a bearing seat 33, a fixing flange 34, a workpiece fixing device 35, an adjusting device 36, and a positioning device 37;

[0055] The two ends of the frame 31 are respectively provided with bearing seats 33, and the upper part of the bearing seat 33 is provided with a bearing cover 38 which is matched with it. The bearing seat 33 and the bearing cover 38 together fix the mandrel 32 on the frame 31; One end of the inner part of the two bearing seats 33 is fixedly provided with a fixing flange 34 , and the other end is provided with a workpiece fixing device 35 . One end of the mandrel 32 is also provided with an adjusting device...

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 gapless rigid 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 of a metallurgical machinery reel part, in particular to a finishing method of a pyramid sleeve of a metallurgical machinery reel part. Background technique [0002] The reel is the main component of the uncoiler and coiler equipment in metallurgical machinery, and the quadrangular 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 quadrangular pyramid sleeve, and the pyramids are arranged in the longitudinal direction of the quadrangular pyramid sleeve and are uniformly distributed around the center of the rotation axis of the quadrangular pyramid sleeve. figure 1 , figure 2 The quadrangular pyramid sleeve shown has 4 groups of pyramids evenly distributed around the circumference, and each group of pyramids includes 2 pyramids that are sym...
