Description

Slitting mill

The utility model relates to a kind of slitting mill.

Slitting mill is made up of three major parts, be rolling cut part, place unreeling part and placing rolling part after the rolling cut part before the rolling cut part, analyze from structure, all also there are some shortcomings in this three part, at first be that spacing between the hobboing cutter adopts packing ring to adjust, adjustment process is pretty troublesome; The secondth, rolling is partly adopted and is concentrated tension mechanism, causes the coiling elasticity of each bundling inconsistent; The 3rd is that the coiled material carrying cylinder that unreels the single diameter of part constitutes a pair of contradiction with the polytropy of coiled material diameter of bore, and the trouble when causing coiled material to install on the coiled material carrying cylinder.

The purpose of this utility model provides that a kind of coiled material is easy for installation, cutter apart from adjust easily, the slitting mill of rolling degree of tightness unanimity.

Solution of the present utility model is that described circle material carrying cylinder is provided with at least three outwardly directed back-up blocks in the tube radially, also be provided with the compression spring that two ends are supported on back-up block respectively and are lifted on the supporting plate of coiled material carrying cylinder in the tube, described packing ring slides on the cutter shaft, this packing ring is provided with the circumferentially uniform and in axial direction flexible push rod in three edges, there is a nut that is set in packing ring then to cooperate with three push rod spirals, be provided with a winder and a left side that is positioned at the winder both sides on the described Scroll between per two adjacent separator discs, a right friction plate and a left side, right brake disc, separator disc, winder, friction plate and brake disc are all joined with the Scroll cunning, and brake disc is provided with the radial screw in the helicla flute that inserts on the Scroll, and the axle head of Scroll also is provided with separator disc, brake disc, the holddown spring that friction plate and winder compress mutually.

The back-up block that but radial elastic stretches on the above-mentioned coiled material carrying cylinder can make internal diameter coiled material within the specific limits be installed on the coiled material carrying cylinder easily and be supported reliably; The packing ring that is arranged on the cutter shaft can make push rod flexible vertically from packing ring by rotating nut, so just can adjust the spacing of hobboing cutter at an easy rate in certain scope; Be arranged on the Scroll helicla flute one can with driving torque equably distribution and transmission give brake disc, two frictional force can offset the brake disc slippage time, make the spring force of holddown spring pass to every pair of friction pair equably, thereby reach the elasticity unanimity of every winder rolling, rolling quality height.

Further illustrate detailed content of the present utility model below in conjunction with drawings and Examples.
