Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
One of the present invention cuts sheet, matrix cross sections is the card of U shape, and the two ends of card U shape are respectively to extending into the face of being polished flat outward, and the edge tilt of polishing plane forms cutting inclined-plane, described polishing plane and fixing polishing material on cutting inclined-plane, the U shape bottom of card is fixed orifices.
Below by embodiment, above content being specifically described, the soldering that embodiment is a polishing hull surface rust mark and solder joint cuts sheet, matrix external diameter 100mm, selects scorching 65Mn steel board of not quenching, thickness 1.1mm, the matrix external diameter r of falling fillet is 0.5, cut face width degree 6mm, bevel angle �� is 15 degree, whole height 12mm, more owing to being polished position plane, polishing intensity is lower, it is 13 15mm that polishing plane width is selected, bottom polishing plane and U shape, the punching press bevel edge r of falling fillet between recessed plane is 4mm, cut after sheet carries out punching press by press tool, matrix after punching press is carried out chamfering, then deoil, the surface treatments such as sandblasting, sheet can be cut as soldering to use, polishing material is selected granularity 35 height of eye grade to cut and is spilt cutting the even cloth in sheet outer end with diamond, polishing plane place arranges according to circular cluster point. bunch some diameter 3mm, same circumference adjacent cluster dot center spacing 10mm. adjacent circumferential spacing 6mm, enters stove carry out soldering by adding solder on the matrix of the polishing material arranged, be fixed on matrix by polishing material.
According to Fig. 1, described in cut the card that sheet cross section is U shape, matrix card is circular, and the U shape bottom of card is fixed orifices 1, described in cut sheet diameter range between 80mm��230mm, it is preferable that diameter be 100mm.
The described height cutting sheet is at least not less than human body palm thickness, and matrix height is greater than 10mm.
The described height cutting sheet is determined by the rotational inertia of abrasive disc and the requirement reducing vibration, and concrete theory is: the system one being had to multiple particle, and its rotational inertia can be calculated by lower formula 1.
In formula formula 1, mi is the quality of single particle, and ri is the distance of single particle apart from central shaft, and I represents its rotational inertia.
If this system is made up of rigid body, it is possible to the rotational inertia of unlimited particle and, namely with its rotational inertia of integral and calculating, such as formula 2, owing to abrasive disc can regard continuous particle body as, therefore, it is possible to carry out integration by formula 2 and seek its rotational inertia.
Iz=�� r2Dm=�� �� r2DV formula 2
In formula 2, Iz is rotational inertia, and r is the distance of particle apart from central shaft.
Can learning by formula 2, when card external diameter is constant, card height is more high, then overall volume is more big, then rotational inertia is more big, then the probability of sharpening machine vibration when adding polishing and amplitude. Then the height of mill is more low more good, but also to be considered human engineering factor, when using hand operated grinding wheel machine to polish, operator hold sharpening machine handle, its hand needs certain terrain clearance, if Grinding wheel disc mill is for being disk shape, then during handle, hand easily contacts polishing surface, easily cause unnecessary injury, and hand-held posture is unfavorable for long-term operation. Therefore in conjunction with hand operated grinding wheel machine, described in cut sheet height should at least be not less than human body palm thickness, i.e. h > 10mm.

What use best bevel angle �� making cuts sheet, operator are when using sander 10 operation installed and cut sheet, cutting inclined-plane and polishing plane keep certain angle, can make to cut sheet and can obtain a thrust forward, this bevel angle �� can ensure that cutting sheet cuts the weld seam of projection, and can ensure that cutting sheet blade edges when polishing welding seams can be discharged abrasive dust by inclined-plane.
Described polishing plane width minimum value can be consistent with cutting surface width, and polishing plane surface arranges polishing material, and the main effect that this structure place arranges polishing material has two: one to be when cutting sheet level and polish, it is possible to play ablation; Two is when cutting sheet cutting inclined-plane and polish, and plays assistance chip removal, the effect of assistant grinding.
The width on described cutting inclined-plane and chip removal, heat radiation are inversely proportional to, and are directly proportional to grinding efficiency, according to the parameter of three, require to determine funtcional relationship, and determine optimum Cutting inclined-plane further, and institute's optimized choice interval range is 3.5mm��12mm, optimum value 6mm.
Width and chip removal, heat radiation, the grinding efficiency parameter three on cutting inclined-plane determine that funtcional relationship principle is: in bruting process, cut sheet grinding hull welding surface, owing to there being material to remove, create a large amount of heats, wherein major part heat is by chip discharge, part heat is absorbed by hull steel, owing to diamond heat-conduction coefficient is the highest, is transmitted to the heat cutting on sheet less. In order to abrasive dust can be discharged smoothly when ensureing polishing, and being taken away by heat, carry out the width on cutting inclined-plane polished and be an inverse relation between chip removal, heat radiation, namely cut surface width more little, heat radiation, chip removal effect are more good; But on the other hand, in unit surface, abrasive particle number is more many, the abrasive particle number participating in grinding is more many, but in the unit time, polishing removal amount is more big, it is possible to grinding efficiency and abrasive particle number are regarded as the relation of a linear increase. And the abrasive particle number in unit surface is consistent with cutting inclined-plane, therefore cutting inclined-plane and grinding efficiency can regard the relation of a linear increase as.
