Pyramid sleeve finish machining device for metallurgical machinery winding drum part

Abstract

The invention provides a pyramid sleeve finish machining device for a metallurgical machinery winding drum part, and relates to the field of pyramid sleeve machining. The pyramid sleeve finish machining device for the metallurgical machinery winding drum part comprises a rectangular pyramid sleeve, a treatment box is arranged on the outer side of the rectangular pyramid sleeve, a deburring structure is arranged inside the treatment box, polishing sand is placed inside the treatment box, a cover plate is arranged at the top of the treatment box, a hinge seat is arranged between the cover plateand the treatment box, the treatment box is rotationally connected with the cover plate through the hinge seat, a gear motor is arranged on one side of the treatment box and fixedly connected with thetreatment box, and limiting structures are arranged on the two sides of the rectangular pyramid sleeve. According to the pyramid sleeve finish machining device for the metallurgical machinery windingdrum part, an expansion head is expanded by gas injected into a hollow rod, at the moment, the inner wall of the rectangular pyramid sleeve is attached more tightly through anti-skid protrusions on the expansion head, the stable fixing effect is achieved, clamping can be facilitated, and subsequent machining is facilitated.

Description

technical field [0001] The invention relates to the technical field of pyramid sleeve processing, in particular to a pyramid sleeve finishing device for 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 surface of the square pyramid sleeve is provided with several pyramids, and the pyramids are arranged longitudinally along the square pyramid sleeve, and at the same time, the rotation axis of the square pyramid sleeve is the center and the circumference is evenly distributed. [0003] The general pyramid sleeve is a cast copper part, the material is soft and the rigidity is poor, and there are no chucks at both ends, so that there is no clamping, alignment and center frame position when the inner hole is processed on the lathe, and there is no suitable tooling plate It has become a big problem to control t...
