Novel end disc diameter stepless adjustable disc type pre-deformer

Abstract

The invention relates to a novel end disc diameter stepless adjustable disc type pre-deformer. The pre-deformer comprises multiple supporting claw discs and a big disc; the big disc comprises a big disc main body, a circular hole is formed in the center of the big disc main body, the big disc main body is provided with sliding grooves which are formed in the direction from the edge of the big discmain body to the radius, and strand passing holes are formed in the positions, located on the sides of the sliding grooves, of the big disc main body; each supporting claw disc comprises a supportingslide plate, wherein multiple threaded holes are formed in one end of the supporting slide plate, and the end, provided with the threaded holes, of the supporting slide plate is connected with a slideway connecting plate through bolts, the cross section of the end, away from the supporting slide plate, of the slideway connecting plate is shaped like T, and an adjusting lead screw with external threads is fixedly connected to the joint of the supporting slide plate and the slideway connecting plate; the supporting claw disc fits the sliding grooves of the big disc through the slideway connecting plates. Accordingly, by making original bolt fixed connection of the supporting claw discs and the big disc improved to be slideway screw stepless adjustable connection of between the supporting claw discs and the big disc, and the problem that an existing disc type pre-deformer cannot achieve end disc diameter linear continuous adjustment is solved.

Description

technical field [0001] The invention belongs to the technical field of steel wire rope pre-deformers, and relates to a novel disc-type pre-deformer with steplessly adjustable end disc diameter. Background technique [0002] At present, the disc-type pre-deformers used by major domestic steel wire rope manufacturers mostly use the connection method of the large disc and the supporting claw disc to be screwed in the end disc diameter adjustment system, and only 2-3 adjustment points can be realized at most. During the wire rope twisting process, in order to ensure the tightness of the wire rope twisting, when determining the twist angle of the wire rope On the premise that it is equal to the design twist angle, the guaranteed twist length S is proportional to the design twist length of the steel wire rope. From a theoretical point of view, steel wire ropes with different specifications and diameters have a corresponding definite twist length S value. Therefore, there are two...
