Abstract

The invention discloses a cutter installation adjustor for a slitting roller. The cutter installation adjustor for the slitting roller comprises a locating ring (1) and a graduated ring (2), and is a helical pair device. Locating marks are arranged on the end face of the locating ring (1), graduation marks and graduation values are arranged on the end face of the graduated ring (2), and the axial distance represented by the interval between every two adjacent graduation marks is 0.01mm; firstly, the graduated ring (2) is turned to be in the state that the graduated ring (2) cannot be turned any more, then, the graduated ring (2) is turned in the reverse direction for a circle, when the graduated ring (2) is turned counterclockwise at the moment, the axial distance of the cutter installation adjustor is increased, and when the graduated ring (2) is turned clockwise, the axial distance of the cutter installation adjustor is reduced. Stepless adjustment is achieved, the precision at the 0.01mm level can be achieved, adjustment is easy and visual, accurate adjustment of the width allowance of a product and accurate adjustment of cutter installation gaps are achieved, a large number of adjusting pads is saved, an unfixed-length spacer bush with the length smaller than 2mm can be replaced, existing operation of cutter installation is difficult and complex, operation of cutter installation through the cutter installation adjustor for the slitting roller can be quite easy, the cost is reduced, energy consumption is reduced, technical difficulty of cutter installation is greatly reduced, and precision of adjustment of cutter installation and working efficiency are improved.

Description

Slitting mill dress cutter adjuster

Affiliated technical field:

The present invention relates to new method in the longitudinally continuous shearing work of cold rolled metal goods, that slitting mill dress cutter regulates.

Background technology:

Longitudinally shear continuously the work of cold rolled metal goods, all to use slitting mill, existing itemize is cut again limit, the key factor that limit quality is cut in impact fills cutter quality exactly, more precisely, be exactly whether gap value between two cuttves is reasonable, this is a complex operations that has suitable difficulty, and dress cutter quality depends on operating experience.General requirement is: while shearing cold-strip steel, by the 10-15% of belt steel thickness, regulate the gap value between two cuttves, by the 30-50% of belt steel thickness, regulate the coincidence amount between two cuttves, also claim interlock amount, material softer, cut precision require when high to get the small value, otherwise get large value.When regulated quantity is reasonable, can make shearing work smooth, reduce load reduction energy consumption, otch section is neat; Gap value is too small, just there will be the defects such as burr, burr, has both destroyed the concordant degree of rolling, is also the main reason of annealing adhesion; Gap value and coincidence amount are excessive, can make to cut limit " setting ", or tearing of limit section cut in generation.Traditional dress cutter control method is: between two adjacent cutterheads, the first coarse adjustment of a plurality of spacers of chuck, shimming carries out accurate adjustment more afterwards, realize the gap adjustment between two cuttves, because pad itself has certain thickness and deviation, institute's adjust the play is exactly an approximation, cannot realize the accurate adjusting in gap, adjusting work needs again a lot of pads, operate and not only bother but also loaded down with trivial details, to improving the quality of product, it is the obstacle that cannot cross over together, also be a difficult problem for one nothing solution, hindered the further raising of product quality, and to consume a large amount of spacers and cost of manufacture, dress cutter adjusting work is neither accurate, time-consuming taking a lot of work again.

Summary of the invention:

The problems that exist in order to solve tradition dress cutter control method, cross over the obstacle that conventional method cannot be crossed over, untie conventional method and cannot untie a Zhe road difficult problem, realize the further lifting of product quality, to meet the requirements at the higher level of different user to product quality, the present invention has designed brand-new dress cutter control method and a technical solution.

This invention solves the technical scheme that its technical problem adopts: with having externally threaded locating ring, on locating ring end face, there is a gauge mark, in the annular distance of location, there is keyway, keyway is for locating with the axle of cutting of slitting mill, with there is internal thread, end face circumference is comprised of the limb of scale division value again calibration groove, the represented axial adjustment distance value of the every little lattice of limb scale is 0.01 millimeter, locating ring and limb are combined into one pair of screw pair, by the rotation to screw pair limb, reach the adjusting of axial distance, realize the accurate adjusting of dress cutter work.

The beneficial effect of this invention is: directly perceived, simple, can realize easily the 0.01 millimetre-sized fine adjustment in product width tolerance and dress cutter gap, can replace 2 millimeters and following spacer and loose chi spacer, allow dress cutter this have suitable difficulty and complicated work, very simple and easy operating become, the cost-saving low power consume that falls, significantly reduce dress cutter technical difficulty, improve dress cutter and reconcile precision and operating efficiency.

Accompanying drawing explanation:

Accompanying drawing is a width 3-D view, 1. locating rings, 2. limb in figure.

The specific embodiment:

In the drawings, the internal diameter of locating ring (1) and keyway press slitting mill cut shaft diameter and key is wide determines, and location with it, locating ring (1) external diameter determines by the external diameter of dress cutter spacer, at the cylindrical of the ladder external screw thread processed of getting on the bus, end face has a gauge mark; Limb (2) has internal thread, and end face circumference has calibration groove and scale division value, and the represented axial adjustment distance of every little lattice scale division value is 0.01 millimeter; Locating ring (1) and limb (2) are combined into one pair of screw pair, after first limb (2) being screwed to the end of to, returning and circle again, now, be rotated counterclockwise the axial distance value that limb (2) increases dress cutter adjuster, the limb (2) that turns clockwise reduces to fill the axial distance value of cutter adjuster, by the method, realizes the work that slitting mill dress cutter precisely regulates gap.

Claims

1. slitting mill fills cutter adjuster, by locating ring (1) and limb (2), formed, it is one pair of screw pair device, its technical characterictic is: on the end face of locating ring (1), have a gauge mark, diameter of bore and keyway press slitting mill cut shaft diameter and key is wide determines, external diameter is determined by the external diameter of dress cutter spacer, thread cutting on ladder cylindrical, after Major Diam adds keyway size according to external diameter and diameter of bore, compromise is determined, rounds numerical value, 1 millimeter of thread pitch (or 2 millimeters); The internal diameter of limb (2) has internal thread, and external diameter determines on the circumference of end face, have calibration groove and scale division value by the external diameter of dress cutter spacer; Gauge deducts two thick remainder values of cutter by minimal product width dimensions to be determined, can not be too thin, to meet instructions for use, be as the criterion.
