Summary of the invention
The object of the invention is to, for the problem of existing wire drawing machine rubbing device frictional disk rotating shaft serious wear pointed in background technology, provide a kind of wire drawing machine rubbing device that can solve foregoing problems.
The technical scheme realizing goal of the invention of the present invention is as follows:
A kind of wire drawing machine rubbing device, it comprises drum cover, frictional disk, friction plate, frictional disk rotating shaft and the Compress Spring for pressing friction dish, the lower end of frictional disk rotating shaft is connected with fixed with drum cover, described friction plate is arranged between drum cover and frictional disk, frictional disk rotating shaft is arranged on the center of frictional disk, between frictional disk rotating shaft and the axis hole of frictional disk, axle sleeve is set, axle sleeve and frictional disk interference fit, axle sleeve inside arranges some roads ball grooves, ball is provided with in ball grooves, the center, top of described frictional disk is provided with boss, described Compress Spring is arranged on boss, Compress Spring top is provided with briquetting, the top threaded engagement of briquetting and frictional disk rotating shaft, the arranged outside of frictional disk pulls out line wheel assembly, the center of drum cover is provided with groove, bottom surface and the friction plate of frictional disk are arranged in groove.
Can freely rotate to make to pull out line wheel, the described line wheel assembly radial direction comprised along frictional disk that pulls out is arranged on pulling out wire wheel axis, be arranged on and pull out pulling out line wheel and pull out wire wheel axis and holding of wire wheel axis outboard end in frictional disk end face outside.The moment of welding wire to frictional disk can be reduced by the end face outside of pulling out wire wheel axis and be arranged on frictional disk, reduce the friction between frictional disk and frictional disk rotating shaft.
Further, the described line wheel that pulls out comprises wheel disc and wire sleeve, and bearing is arranged in wire sleeve.
Wire drawing machine rubbing device of the present invention arranges axle sleeve between frictional disk and frictional disk rotating shaft, axle sleeve inside arranges multiple tracks ball grooves, in ball grooves, ball is set, when pulling out line wheel upper generation moment, by the rolling friction between the inner ball of axle sleeve and frictional disk rotating shaft, moment is eliminated, reduce the wearing and tearing of frictional disk rotating shaft largely, extend the service life of frictional disk rotating shaft.In order to prevent the dislocation between friction plate and frictional disk and drum cover, groove is provided with in the bottom of drum cover, the bottom surface of frictional disk and friction plate are all arranged in groove, effectively can prevent the generation misplaced, between frictional disk and drum cover, the frictional force of appropriateness, makes welding wire to be closely wrapped on reel.
