Summary of the invention
The utility model is the mechanical drum-type tire reverse wrap molding mechanism of the stability that solves the technical problem that exists in the known technology and provide a kind of and reduce the sidewall windrow, improve the secter pat motion and reliability.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of mechanical drum-type tire reverse wrap molding mechanism; Comprise positioning disk that to be installed on the axle sleeve relative with cylinder block, be located at the secter pat between cylinder block and the positioning disk and be supported on the anti-package running roller on the positioning disk arc surface; It is characterized in that: said positioning disk is made up of the positioning disk chorista that positioning disk matrix and the activity of being uniformly distributed along the circumference are inlaid on the positioning disk matrix; Said positioning disk chorista is packed in through securing member on the side of said secter pat, and said anti-package running roller is located on the arc surface of positioning disk split.
The technical scheme that the utility model can also be taked is:
Repair welding has the filling metal between the end of said securing member and the arc surface.
On the side that screw that said positioning disk distributes through alternatively up and down and bearing pin are packed in secter pat.
Said anti-package running roller is made up of running roller body and the roller shell that is fastened on the running roller body, the circular arc camber that the outer surface of said roller shell adopts the curvature with carcass to be complementary, and said running roller body and roller shell are made by nylon material and antiseized flexible material respectively.
Advantage and the good effect that the utlity model has are:
Adopt said structure; When secter pat was radially locked the carcass wire loop, drive lead dish chorista and the running roller that is located on its arc surface moved simultaneously, carcass anti-package end points is propped up highly reduced; Guarantee that the anti-package running roller begins the pressing carcass from root, and then reduce the sidewall windrow; In addition, the positioning disk chorista cooperates with the positioning disk matrix, has strengthened the guiding distance of secter pat in positioning disk one side, guarantees that secter pat is the bilateral guiding in whole movement travel, guaranteed the stability and the reliability of secter pat motion; The anti-package running roller further is made up of rigid running roller body and flexible roller shell; Guaranteeing under running roller and the situation that carcass fully contacts; Form the buffering of active force in both direct contact portions, and then reduce the depth of cup of carcass upper roll wheel, improved the Forming Quality of product.
