Abstract

The invention relates to a closed straightening frame. A straightening frame body, two or more straightening rollers, straightening roller fixing frames and fixing pieces are included. The two or morestraightening rollers are oppositely arranged and used for straightening steel bars. The straightening roller fixing frames are fixed to the straightening frame body through the fixing pieces. Dustproof covers are arranged on the outer sides of the fixing pieces. Sliding grooves are formed in the fixing pieces. The straightening roller fixing frames are provided with circular grooves. The closedstraightening frame further comprises positioning balls, and the straightening roller fixing frames and the fixing pieces relatively slide through cooperation of the circular grooves, the positioningballs and the sliding grooves. Different from the prior art, the inner hiding type dust sealing and lubricating design is adopted, inner hiding type positioning (balls) is adopted, loosening preventing and self-locking are achieved, the structure is compact, the dustproof effect is good, the inner lubrication condition is good, structure connection is firm, safety performance is good, and the integral service life is long.

Description

technical field [0001] The invention relates to the technical field of steel bar processing, in particular to a closed straightening frame. Background technique [0002] In the prior art, the size of the straightening roller fixing frame of the straightening frame is too large, the dust on the straightening rollers is easy to get stuck, and the straightening rollers often cannot rotate. [0003] The adjustment bolts are external, and the dust-proof effect is poor. The adjustment bolts are fixed with snap rings, which are easily damaged, causing the entire straightening roller fixing frame to reverse and loosen continuously during use, poor safety performance, and short service life; the adjustment bolts directly Installed on the body of the straightening frame, it is easy to lose the straightening frame directly; using exposed positioning pins, it is easy to fall off and cause straightening failure; the radial dimension of the entire straightening frame is large, the rotatio...
