Abstract
The invention discloses a circle shear blade repairing and sharpening device which comprises a roll grinder. A circle shear clamping mould is installed on a rack of the roll grinder and a rotary power system of the circle shear clamping mould serves as the roll rotation power system of the roll grinder. A main body of the circle shear clamping mould is a waste roller, namely the work surface of the waste roller is machined into a smooth axial plane matched with an inner diameter of the circle shear besides one end is provided with clamped shroud. A clamped groove used for installing circle shear clamping disc is machined on the machined smooth axial plane, wherein the width of the clamped groove for installing the circle shear clamping disc is matched with the circle shear clamping disc, the distance between the clamping groove and the clamped shroud and the thickness of the clamped circle shear are a multiple relation. The circle shear blade repairing and sharpening device is high in repair quality and small in repair workload, the amount of machining can be flexibly controlled according to the abrasion of the blade of the circle shear, and the service life of the circle shear can be extended to the maximum.
Description
Technical field
The present invention relates to a kind of polishing device, especially a kind of circle shear blade repairing and sharpening device.
Background technology
At present, rolling plate enterprise all adopts the turning method for processing to recover the cutting edge of circle shear.The shortcoming of this repair mode is that processing capacity is big, and general each processing needs turning to fall 8mm thickness, causes the service life of circle shear short.And there is the processing knife mark at the cutting edge place of the circle shear of this repair mode reparation, and repairing quality is low, directly causes sheet material limit cutting accuracy low, has influenced the quality of sheet material.If circle shear is not repaired utilization, the significantly raising with causing product cost influences the competitiveness of product in market.Therefore, designing a kind of repairing quality height, repair the little circle shear blade repairing and sharpening device of processing capacity, is the present technical issues that need to address.
Summary of the invention
Technical problem to be solved by this invention provides a kind of repairing quality height, repairs the little circle shear blade repairing and sharpening device of processing capacity.
The technical scheme that the present invention solves its technical problem is:
A kind of circle shear blade repairing and sharpening device; Form by roll grinder; On the stand of roll grinder, circle shear is installed and clamps mold; The rotary power system that circle shear clamps mold is the roll rotary power system of roll grinder, and described circle shear clamps the main body of mold for scrapping roll, and the working face that is about to scrap roll clamps the convex shoulder except that at one end staying; All the other are processed into the smooth axial plane with circle shear internal diameter coupling; And be used to the card holding trough that circle shear clamps dish is installed in the smooth axial plane processing that processes, being used to install the width that circle shear clamps the card holding trough of dish and clamping the dish coupling with circle shear, card holding trough becomes multiple to concern with the distance that clamps between the convex shoulder with the thickness of the circle shear that clamps.
The technical scheme that the present invention solves its technical problem can also be:
Circle shear of the present invention clamps dish and is made up of two half-round clamping rings; All be processed with at least two at each half-round clamping ring and clamp disc radial trip bolt unthreaded hole and at least two circle shears axially fasten the screw thread hole; Circle shear axially fastens the screw thread hole and clamps disc radial trip bolt unthreaded hole and mutually disjoints; In card holding trough, radially be processed with and clamp the tapped blind hole of disc radial trip bolt unthreaded hole coupling; Circle shear clamps dish and fixes through the main body that first trip bolt and circle shear clamp mold, and circle shear is installed on circle shear through second trip bolt and clamps on the mold.
The present invention all is processed with two at each half-round clamping ring and clamps disc radial trip bolt unthreaded hole and two circle shears axially fasten the screw thread hole, in card holding trough, radially process four with the tapped blind hole that clamps disc radial trip bolt unthreaded hole coupling.
The invention has the beneficial effects as follows:
Compared with prior art; The present invention is high to the cutting edge repairing quality of circle shear, the reparation processing capacity is little; The reparation processing capacity is reduced to below the 5mm by the 8mm of turning, and can grasp processing capacity flexibly according to circle shear cutting edge abrasion condition, can prolong the service life of circle shear to greatest extent.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
The specific embodiment
A kind of circle shear blade repairing and sharpening device; Form by roll grinder; On the stand 1 of roll grinder, circle shear is installed and clamps mold 2; The rotary power system that circle shear clamps mold 2 is the roll rotary power system of roll grinder, and described circle shear clamps the main body of mold 2 for scrapping roll, and the working face that is about to scrap roll clamps the convex shoulder 3 except that at one end staying; All the other are processed into the smooth axial plane with circle shear internal diameter coupling; And be used to the card holding trough that circle shear clamps dish 5 is installed in the smooth axial plane processing that processes, being used to install the width that circle shear clamps the card holding trough of dish 5 and clamping dish 5 couplings with circle shear, card holding trough becomes multiple to concern with the distance that clamps between the convex shoulder 3 with the thickness of the circle shear that clamps 4.Described circle shear clamps dish 5 and is made up of two half-round clamping rings; All be processed with at least two at each half-round clamping ring and clamp disc radial trip bolt unthreaded hole and at least two circle shears axially fasten the screw thread hole; Circle shear axially fastens the screw thread hole and clamps disc radial trip bolt unthreaded hole and mutually disjoints; In card holding trough, radially be processed with and clamp the tapped blind hole of disc radial trip bolt unthreaded hole coupling; Circle shear clamps dish 5 and fixes through first trip bolt 7 and the main body that circle shear clamps mold 2, and circle shear 4 is installed on circle shear through second trip bolt 6 and clamps on the mold 2.All be processed with two at each half-round clamping ring and clamp disc radial trip bolt unthreaded hole and two circle shears axially fasten the screw thread hole, in card holding trough, radially process four with the tapped blind hole that clamps disc radial trip bolt unthreaded hole coupling.
