Abstract

The utility model discloses a pinch roll device for introducing strip steel into a slitting shear. The device is arranged between an outlet side guide of a temper mill and the slitting shear, and comprises a base, a rotation shaft, swinging arms, pressing rolls, a guide plate and supporting rolls, wherein the rotation shaft is arranged on the base; the swinging arms are fixed on two sides of the rotation shaft; the pressing rolls are arranged on the end parts of the swinging arms by pressing roll bearing seats; the guide plate is welded on the swinging arms; the supporting rolls are arranged on the base by supporting roll bearing seats; a gap, through which the strip steel can pass, can be formed by each pressing roll and the corresponding supporting roll under a condition that the swinging arms are pressed downwards, so that the strip steel can be smoothly introduced into the slitting shear. By virtue of the guide plate on the swinging arms, the head raising of the strip steel is avoided, the strip steel can be effectively guided to smoothly enter the slitting shear, the production efficiency is improved further, and the hidden dangers of personal injury are reduced; when the strip steel is silt, the pressing rolls swing to be pressed downward under the driving of the swinging arms, the strip steel in the gaps between the pressing rolls and the supporting rolls can be smoothly guided into the slitting shear for slitting, the smoothness and the non-deflection of the strip steel and the parallel and level performance of cutting openings of the strip steel can be ensured in the shearing, the shearing quality of the strip steel is improved, and the product yield is improved.

Description

For with steel, importing and cut the pinch roll apparatus of cutting

Technical field

After the utility model related to belt steel flating, the pinch roll apparatus of cutting was cut in importing.

Background technology

That smooth unit is mainly that the coil of strip to normal temperature state after hot rolling carries out is smooth, bundling and rewinding, to improve band steel mechanical performance, improves belt plate shape and strip surface quality, after cutting and cutting the outlet side guide and guard that are arranged in planisher, for bundling and back-end crop.

Characteristic due to the raw material roll bending, during the coil of strip uncoiling, take the lead into crooked recessed shape, the staff is in order to facilitate threading, through the uncoiler outlet side of being everlasting, will be with steel up to push up, straight the entering in entrance pinch roll of this belt transect steel ability, but with steel, there is following defect through the smooth laggard method of operation of cutting of cutting: 1, due to the very thin characteristic of steel, situation with the steel nose often appears in guide and guard place of planisher outlet side, easily by other equipment top distortion, must the staff when serious standing on equipment tramps with one's feet carries out threading work at surface of steel plate, namely affect production efficiency, there is again personal injury hidden danger, 2, in threading, also need the another one staff ruuning situation of observation band steel taping head at any time, notify in time the staff to adjust, cause in smooth unit running process not only time-consuming but also effort, affect production efficiency, 3, due to the band steel while cutting, is not pushed down to the band steel in advance, while meeting the band steel to be cut of deflection, the band steel enters to cut after the equipment of cutting is sheared and the otch deviation phenomenon easily occurs, affects greatly the product lumber recovery.

Summary of the invention

The purpose of this utility model is exactly for above-mentioned defect, provide a kind of be used to steel, importing and cut the pinch roll apparatus of cutting, guide after smooth the band steel smoothly by this pinch roll apparatus enter cut cut, without the nose phenomenon, while simultaneously effectively guaranteeing to shear, straight, the deflection not of band steel, improve the shearing quality with steel.

For achieving the above object, the utility model designed be used to steel, importing and to cut the pinch roll apparatus of cutting, between being arranged on the outlet side guide and guard of planisher and cutting and cut, described pinch roll apparatus comprises base, be arranged on the rotating shaft on base, and the swing arm that is fixed on the rotating shaft both sides, described pinch roll apparatus also comprises the pressure roller that is arranged on the swing arm end by the pressure roller shaft bearing, be welded on the guide plate in swing arm and be arranged on the carrying roller on base by supporting roller bearing seat, described carrying roller and pressure roller form when swing arm is in depressed state can be for the gap of passing with steel, thereby making to be with steel to import to cut smoothly cuts.

Further, described swing arm upper end is provided with to the bending part of carrying roller direction inclination, and described guide plate is welded on the bending part of swing arm.

Further, between the bending part of described guide plate and swing arm, be welded with some reinforcements.

Further, described pinch roll apparatus also comprises driving swing arm oscillating motor, and the cylinder body of described hydraulic cylinder is hinged on base, and the tailpiece of the piston rod of described hydraulic cylinder is hinged on bearing, and described bearing is fixed in swing arm.

Further, the end of described rotating shaft is fixedly connected with sleeve, and described sleeve is rotatably assorted by lining and connecting axle, and described connecting axle is fixed on base by axle end baffle plate.

The utility model has the advantage of: this device, by the guide plate in swing arm, has been avoided the nose with steel, during effectively the pilot tape steel enters smoothly and cuts and cut, thereby enhances productivity, and reduces personal injury hidden danger; When the band steel need to be cut, swing arm band dynamic pressure roller swings to depressed state, the band steel imports to cut smoothly in pressure roller and carrying roller gap cuts middle preparation sub-cut, belt steel flating while guarantee shearing, non-deflection, band steel otch are concordant, improve the shearing quality with steel, improved the product lumber recovery, improved product quality, therefore, have higher production, safety, economic benefit.
