Abstract

The utility model discloses a special-shaped glass cutting machine. The glass cutter 11 of the special-shaped glass cutting machine can be controlled to rotate by a handle 7, and can move back and forth on a suspension arm 6 by the guiding of a profiling bar 11; a rotating cutter seat can ensure the cutter point of the glass cutter 11 facing to the direction of movement always for cutting. The utility model can cut the special-shaped glass of optional shapes and sizes. The utility model has the advantages of reasonable design, convenient operation and low cost, and is an ideal special-shaped glass cutting tool.

Description

The special-shaped glass cutting machine

The utility model relates to a kind of machine of glass-cutting, particularly a kind of special-shaped glass cutting machine that cuts out arbitrary shape glass.

At present, use more glass-cutting apparatus to be the pen type glass cutter on the market, it has simple in structure, and characteristics easy to use are comparatively suitable for cutting straight line, but as special-shaped glass such as incising circular, ellipse, pentagram, hearts, then be difficult to be competent at, other improved a bit glass cutter is as loading onto kerosene etc. in the glass cutter, also do not solve the problem of cutting special-shaped glass, therefore have significant limitation.

The purpose of this utility model provides a kind of simple and reasonablely, easy to use, can cut out the special-shaped glass cutting machine of any special-shaped glass.

The purpose of this utility model is achieved in that cutting machine is by base 1, one end is fixed on the support arm 2 on the base, but the vertical direction rotating shaft 8 by handgrip 7 controls of rotating on the support arm 2, be fixed on compositions such as the horizontal cantilever 6 of rotating shaft 8 lower ends and glass cutter 10, it is characterized in that: a knife rest 5 that can move around along cantilever 6 is housed on the cantilever 6, knife rest 5 lower ends are fixed with a vertical profiling bar that can contact with master plate 12 11 and a rotating tool rest 9 are housed, be fixed with glass cutter 10 on the rotatable tool rest 9, cantilever 6 and rotating shaft 8 relative ends are equipped with an elastic force adjusting screw(rod) 4, spring 3 one ends connect elastic force adjusting screw(rod) 4, and the other end connects knife rest 15.

The utility model principle of work is: when needs cutting special-shaped glass, earlier make a hollow master plate 12 according to desired shape, then master plate 12 is fixed on the base 1, by adjusting the high and low position that screw 16 mixes up glass cutter 10, and suitably adjust the tightness of springs 3 by elastic force adjusting screw(rod) 4 according to the size of different master plates 12, the profiling bar 11 that makes of the effect of spring 3 leans against on the inner edge of master plate 12 all the time, rotate handgrip 7, thereby profiling bar 11 cuts on glass 17 along the master plate 12 inner edges glass-guiding cutter 10 that moves, the knife edge that rotatable tool rest 9 makes glass cutter 10 is beneficial to cutting all the time along the working direction of glass cutter 10.When handgrip 7 rotates a circle, just finished the work of cutting non-conventional glass.Another characteristics of the present utility model are, by adjusting the position of knife rest 5, when glass cutter 10 and rotating shaft 8 more near the time, just can cut out arbitrarily small special-shaped glass.

Because the utility model has adopted movable carriage and rotatable tool rest and other supporting device, makes the special-shaped glass cutting machine can cut out arbitrary shape and arbitrarily small special-shaped glass, this is that present prior art is difficult to realize.And the utlity model has simple and reasonablely, easy to operate, low, the good effectiveness of cost is a kind of comparatively ideal parting tool, is suitable for applying.

Below in conjunction with accompanying drawing the utility model is elaborated.

Fig. 1 is a special-shaped glass cutting machine structure synoptic diagram;

Fig. 2 is the A-A sectional view;

Fig. 3 is the oval master plate structural representation of using of cutting;

Fig. 4 is the heart-shaped master plate structural representation of using of cutting;

Fig. 5 is a cutting pentagram backup plate structural representation.

When needs cutting special-shaped glass, on master plate 12, dig out earlier a hollow desired shape, because of between profiling bar 11 and the glass cutter 10 distance being arranged, so howing than the size of actual needs, the hollow shape on the master plate 12 goes out this distance in advance, then that master plate 12 usefulness retaining screws 18 are solid on fixed leg 19.In order to make knife rest 5 move left and right neatly, be equipped with both sides, knife rest 5 upper end can be along the pulley 13 of 15 slips of the groove on the cantilever 6, groove 15 is in the motion that does not run through near elastic force adjusting screw(rod) 4 one ends with restriction pulley 13, spring 3 one ends are connected on the knife rest 5, and the other end is connected on the elastic force adjusting screw(rod) 4, like this, by regulating elastic force adjusting screw(rod) 4, the elasticity of control spring 3 just can make the profiling bar 11 on the knife rest 5 nestle up the inner edge of master plate 12 all the time, and move flexibly.Tool rest is constantly changed direction when considering the cutting special-shaped glass, so be designed to rotatable tool rest 9, rotatable tool rest 9 is fixed on the interior ring of pulley 14, and the outer shroud of pulley 14 is fixed on the knife rest 5, and rotatable tool rest 9 can be rotated on knife rest 5 flexibly.Unscrew screw 16 and glass cutter 10 is adjusted to be close to glass 17, screw screw 16 then glass cutter 10 lockings.Before the glass-cutting, earlier at the kerosene of embrocating on glass,, and regulate the knife edge direction of glass cutter 10 in case glass cutter 10 skids, compress handgrip 7 then, at this moment support arm 2 distortion slightly under pressure makes glass cutter 10 more tight with combining of glass 17, then rotary handle 7, promptly begin cutting, under rotatable tool rest 9 effects, can constantly revise the direction of glass cutter 10 knifes edge by rotation, make it consistent with direction of motion all the time.In the process of rotary handle 7, profiling bar moves along master plate 12 inner edges, and glass-guiding cutter 10 cuts out the same special-shaped glass of hollow shape that makes in advance with master plate 12 on glass 17, and handgrip 7 rotates a circle, and finishes cutting action.

Embodiment 11, foundation of incision machine 1 is made by cast iron, base upper berth one deck soft cloth during glass-cutting, support arm 2 is made by spring steel, spring 3 adopts the high-quality spring, and glass cutter 10 adopts steel alloy, and master plate 12 adopts the high-quality three-ply-wood, all the other devices are made by the high-quality steel, and wherein fixed part adopts riveted joint.

Embodiment 2, and master plate 12 adopts hard plastic board, the fixedly employing welding that device is 3, and all the other and embodiment 1 are together.
