A kind of inner hole wall is processed with the glass cutting of ring groove and uses Knife flywheel blade
Technical field
The utility model relates to the glass cutting that a kind of inner hole wall is processed with ring groove and uses Knife flywheel blade, belongs to technical field of tools.
Background technology
The endoporus of break bar is in order to be installed on the cutter shaft, and cutter shaft then is installed on the knife rest, and knife rest is installed on the handle or on the glass cutting machine.Break bar foreign aid cutting edge is pressed in glass surface; Drag handle or move and be installed in the knife rest on the machine; Break bar can produce rolling because of the resistance of glass surface, forms an impression at glass surface, because of the fragility of glass; This impression can form a lacinia line of glass surface, thereby realizes the cutting to glass.
Break bar exists following several kinds of inner hole walls at present:
Conventional break bar endoporus, the inner hole wall of most break bars is slick cylindrical surface, can reduce the friction resistance on break bar inner hole wall and cutter shaft surface like this, so that realize smooth and easy cutting.But this break bar in use, and when cullet got between break bar endoporus and the cutter shaft, the normal rolling that tends to block break bar caused cutting normally not carry out.
The vibration break bar, the technology that processes on a kind of hole wall perpendicular to break bar side plane groove has then been invented by Japanese TOYO company.Use the break bar of this technology, cutting edge can produce regular vibration when glass-cutting, thereby increases the degree of depth of cutting.Also help collecting and removing the cullet that sticks to the cutter shaft surface, thereby reduce the cutting fraction defective.
Summary of the invention
The purpose of the utility model is that the glass cutting that provides a kind of inner hole wall to be processed with ring groove uses Knife flywheel blade.
Knife flywheel blade is used in the glass cutting that the utility model provides a kind of inner hole wall to be processed with ring groove, at endoporus cannelure is arranged.
This ring groove can be one, also can be many.
The utility model utilizes the main effect of this groove to be:
Effectively remove or collect the cullet of entering break bar endoporus, thereby prolong normal clipping time, reduce the cutting fraction defective;
Break bar bore surface and cutter shaft surface contact area diminish, and can reduce the vacuum adsorption force that may exist between break bar bore surface and cutter shaft surface.Thereby make cutting more smooth and easy.

Embodiment
Referring to figs. 1 through Fig. 9 the embodiment of the utility model is described.
Embodiment: extremely shown in Figure 9 like Fig. 1;
Obviously, the many modifications made based on the aim of the utility model of those skilled in the art and the variation protection domain that belongs to the utility model.
Embodiment 1: extremely shown in Figure 3 like Fig. 1; A kind of inner hole wall is processed with the glass cutting of ring groove and uses Knife flywheel blade, and the axis of cannelure 2 perpendicular to break bar endoporus cylindrical surface arranged in the endoporus of grinding block 1.
Embodiment 2: extremely shown in Figure 6 like Fig. 4; A kind of inner hole wall is processed with the glass cutting of ring groove and uses Knife flywheel blade, and the axis of cannelure 7 perpendicular to break bar endoporus cylindrical surface arranged in the endoporus of Knife flywheel blade 6, and cannelure 7 is many, extends to the other end from an end of cylindrical hole.
Embodiment 3: extremely shown in Figure 9 like Fig. 7; A kind of inner hole wall is processed with the glass cutting of ring groove and uses Knife flywheel blade, and cannelure 8 is arranged in the endoporus of Knife flywheel blade 6, and cannelure 8 is many, extends to the other end from an end of cylindrical hole, and cannelure 8 forms the oblique angle with the axis on break bar endoporus cylindrical surface; Or be called the screw-type groove.
Embodiment 4: a kind of inner hole wall is processed with the glass cutting of ring groove and uses Knife flywheel blade, at endoporus the axis of cannelure perpendicular to break bar endoporus cylindrical surface is arranged, and this ring groove can be one, also can be many.
As stated, the embodiment of the utility model has been carried out explanation at length, but as long as break away from the inventive point and the effect of the utility model in fact a lot of distortion can not arranged, this will be readily apparent to persons skilled in the art.Therefore, such variation also all is included within the protection domain of the utility model.
