Description
Technical field
The relevant a kind of cutters that are used to cut off hard brittle material of the present invention, the particularly relevant cutters that are used to cut off glass.
Background technology
At first, the cut-out with regard to hard brittle material is that example illustrates with glass.Cut off in the method for glass, following method is widely used.That is to say that a kind of method is that utilization has the diamond cutters of diamond blade or the wheeled cutters of cemented carbide cut (line) glass surface, produce the crack near making glass, apply bending moment or surging force etc. along this crack, to allow the crack cut off glass at the glass internal growth.
For example, Figure 18 is the situation of expression when making the crack betide sheet glass 101 with the glass cutting cutter 100 of setting up break bar.The break bar 3 of cemented carbide by after being pressed in glass surface, in case press pressure surpasses the threshold value of the stress-strain of glass, then with on the vertical direction of pressure direction (plate face) is just produced crack 102.This crack is called vertically split.If this vertically split one grows to the opposite side that arrives sheet glass, sheet glass 101 just is cut off.
In the big occasion of press pressure, in the horizontal direction splay crack 103 will take place simultaneously.This crack is called horizontal slit.Horizontal slit one takes place, and then opens because of this progress of fracture, so press pressure is cancelled, cuts off the expansion of going up important vertically split and will hinder.Simultaneously the glass on surface peels off and becomes smear metal.
Thereby, when cutting a piece of glass the surface, importantly do not allow horizontal slit take place with the glass cutting cutter.
Influence in the factor of this line, representative have following several:
(1) cutters: kind, material, point of a knife angle, (break bar diameter: the occasion of wheeled cutters)
(2) glass: the characteristic of near surface, glass are formed, residual stress
(3) line condition: point of a knife load, line speed
(4) environment: the temperature of air and humidity, cutters have or not with oil
For correctly cutting off plate glass, need to obtain dark vertically split.Therefore, become big as long as allow the nose angle degree become big and allow point of a knife load.Again, the occasion of wheeled cutters makes the break bar diameter become greatly also effective.
Hand-held glass cutting cutter also streaks when the glass surface, and when beginning to rule, the load that is applied to mostly on the point of a knife is all not enough.Therefore, often can't allow effective vertically split take place.Partly be called " cut-in without ball part " in this line that this effective vertically split will not take place.During cut-in without ball, the line sound of the uniqueness that vertically split caused (just like hair or fiber because of by the short sound that is sent of burning shrinkage) can not take place.
On the line starting point, if can not obtain effective vertically split, when then for example sheet glass being cut off in the mode that applies stress in bending, the part of this cutting starting point can't correctly be cut off, and makes glass that the unfavorable conditions such as part of unfilled corner be arranged.It will be difficult beginning just to obtain effective vertically split in particular for the sheet glass as thin as a wafer of liquid-crystal display etc. from the starting point of ruling.
Summary of the invention
The object of the present invention is to provide a kind of hard brittle material cutters, begin to make effective vertically split to take place by the simple mechanism starting point of can ruling certainly.
Another object of the present invention is to provide a kind of scriber and a kind of scribble method that uses these cutters, make line just can produce effective vertically split at the beginning.
For achieving the above object, hard brittle material cutters of the present invention, it comprises that hard brittle material cuts off with blade, is used to the tube portion that supports the back shaft of described blade and be used to take in described back shaft, it is characterized in that: described tube portion be arranged to make described back shaft be held in can before and after slide, be provided with in the inside of described tube portion: elastomerics; Weight or first attracts member; And travel mechanism, under described elastomeric effect, make described weight or first attract member to move, impact to produce.
Described weight moment gets back to and opens the beginning during position, and described back shaft is passed on to described blade and impacted;
Described weight has recess, and described travel mechanism has coniform body; When cutting off beginning, hold described tube portion and described blade is pressed in when being cut off on the member, make described back shaft mobile both quantitative, and the part of described coniform body embedded described recess set on the described weight and move in described tube portion inside;
Described first when attracting member moment to get back to zero position, and described bolster is passed on to described blade and impacted;
Described travel mechanism has second and attracts member, and when cutting off beginning, described tube portion slides described back shaft, so that described first attracts member moment to leave the second attraction member and move.
In the described tube portion air introducing mechanism is set, described second attracts member to be arranged to have the function of piston, to utilize pneumatics set line pressure is set for and can be changed.
Main on the elastomerics with whisker, compression spring etc., and the elastomeric material of soft or resin material also can.
If adopt hard brittle material cutters of the present invention, when both then cutter head portion being compressed into quantitatively, travel mechanism can start, and the point of a knife by the tool setting head due to this startup applies surging force, begin just to form effective vertically split from line, and can eliminate the cut-in without ball phenomenon at hard brittle material.

Embodiment
Fig. 1 is the profile construction of the glass cutting cutter 1 of the expression first embodiment of the present invention.Glass cutting cutter 1 is made of following two portions:
1. the body 1a that is constituted by cylindrical shell 2;
2. the 1b of cutter head portion will for example be installed in maintaining part 4 by break bar 3 rotations that tungstenalloy constituted freely.
The 1b of cutter head portion passes the axle support section 7 of being installed on cylindrical shell 2 lower ends by axle 6 set on the maintaining part 4, so that can slide at above-below direction.This upper end of 6 has the head 8 of rivet-like, in order to avoid this axle 6 comes off on described shaft supporting part 7.
In addition, the present invention as described later, when when line, the glass cutting cutter was both quantitative in order to axle 6 is upwards pushed with the 1b of cutter head portion, and tool setting head 1b applies surging force, so axle 6 has axial both quantitative stroke.
In the hollow bulb as the cylindrical shell 2 of handle portion, be formed for its hollow space is divided into flange shape fastener 2a up and down.On this fastener 2a, shown in being seen amplification profile on the A-A ' of Fig. 1 alignment, on its eccentric position, form circular window 10.This fastener 2a is in fact one-body molded with cylindrical shell 2.
At the following hollow bulb of fastener 2a, take in the push rod 11 with head 8 butts of described axle 6, at the following hollow bulb of fastener 2a, take in be used to allow the set weight that surging force takes place hammer portion 12 and be used for hammer portion 12 is applied the whisker 13 that suppresses.Screw togather a bolt 15 on the top 14 of body 1a, the upper end of whisker 13 is pushed in the lower end of this bolt 15.Therefore, move up and down by rotating this bolt 15, so that suppressing of whisker 13 can be adjusted.
Described push rod 11 is that the hollow bulb internal diameter that its external diameter is made than cylindrical shell 2 bottoms is little approximate number millimeter, and is in trip embedding state in this hollow bulb.In addition, form cone 16 in the upper end of push rod 11, and on the top ends of this cone 16, form thin column 17.External diameter in described cone 16 bottoms is little than push rod 11 external diameters, and the whisker 18 of circular cone shape is set between shoulder that is produced on push rod 11 and the fastener 2a whereby.By this whisker 18, push rod 11 applied downwards suppress, and make described column 17 when standby, be matched with the central shaft of hollow bulb.
On the position of the off-centre (right-hand among the figure) below above-mentioned hammer portion 12, form towards last hole 19.The diameter in this hole 19 is bigger a little than the diameter of the column 17 of push rod 11.In the amplification profile of A-A ' line, the window 10 of fastener 2a is on the position of the column 17 that comprises described hole 19 and push rod 11.
In addition, in hammer portion 12, shown in the amplification profile of B-B ' line, on direction of principal axis, form a pair of groove 12a, and on the direction of principal axis of the inner peripheral surface of cylindrical shell 2, form projection 2b, to engage described groove 12a.Whereby, hammer portion 12 limits the rotation of its circumferential direction when moving up and down.
In addition, as long as the substitute of whisker 13 and 18 can obtain equal function, other elastomerics also can.
The action of described cutters 1 will illustrate with reference to main the amplification profile of (a) among the figure 2 to (d).Figure (a) occasion when being standby, the state identical with Fig. 1.Secondly, in case the body 1a that holds pressed downwards and with break bar 3 by being pressed on the sheet glass, push rod 11 rises with regard to the elastic force pressure of opposing whisker 13.If cone 16 surfaces of this push rod 11 are fastener 2a at a touch, afterwards, shown in figure (b),, push rod 11 rises on one side itself just changing direction toward clockwise direction on one side.
Figure (c) is the occasion that column 17 that expression is positioned at these cone 16 tops has been matched with formed holes 19 below the hammer portion 12, and afterwards, shown in figure (d), hammer portion descended 12 moments, and the upper surface of the face Z in this hole 19 bump column 17.At this moment, the downward surging force that is taken place reaches the break bar 3 of the 1b of cutter head portion via push rod 11 and axle 6.
So, before surging force takes place, with the 1b of cutter head portion by being pressed on the sheet glass, and after confirming the generation of this surging force, with common the same line of occasion.If the press pressure that the generation of this surging force is required is made as at the needed cutting pressure of line starting point, then can apply best cutting pressure in the line starting point.
In addition, applying the state of cutting pressure, because of surging force via break bar 3 to glass sheet, so the growth of vertically split can be obtained dark vertically split by promotion more.
Fig. 3 is the mode chart that is illustrated in this glass cutting cutter 1 formed vertically split.Begin to light the effective vertically split C of formation on sheet glass 101 from line.Relatively, be as shown in Figure 4 by existing glass cutting cutter 100 formed vertically split C, exist the part of cut-in without ball at the line starting point initial stage.
In the glass cutting cutter 1 of Fig. 1, as triggering for generating mechanism, constitute the vertical columns 17 of push rod 11 and embed the hole 19 of hammer portions 12, but in another triggering for generating mechanism as shown in Figure 5, after forming the hole 19 ' of 2 grades of formations, the recovery of whisker 13 is divided into secondary and can produces secondary pulse power in hammer portion 12 '.
Fig. 6 is the sectional view of the example of the expression cutter head 1b of portion.At the axle 6 inner cotton cores 25 that insert, soak on this cotton core 25 and contain cutters with oily.The end contact break bar 3 of cotton core 25 is so that can supply with cutters with oily.
Fig. 7 is the glass cutting cutter 1 ' of the expression second embodiment of the present invention.As shown in Figure 1, be the circumferential direction rotation of restriction hammer portion 12, form projection 2a and become groove 12a at the inner peripheral surface of cylindrical shell 2, but must do trickle processing for this reason in the peripheral shape of hammer portion 12.
Therefore, on the glass cutting cutter 1 ' of Fig. 7, below hammer portion 12 ', form cyclic groove 26, to replace described hole 19.Whereby, even hammer portion 12 ' rotates at circumferential direction, when rake 21 and fastener 2a butt, after push rod 20 tilted toward the clockwise direction, its column 22 necessarily embedded grooves 26.
In addition, on this glass cutting cutter 1 ', the head 8 ' of axle 6 forms the plane, and on the contrary, the bottom 23 of push rod 20 forms bowl-shape, can stand voluntarily because of push rod 20 during standby, so the whisker 18 that Fig. 1 adopted will not need.
Fig. 8 is the profile construction of the glass cutting cutter 31 of the expression third embodiment of the present invention, and the member corresponding with Fig. 1 adopted the common label.In the middle of the upwardly extending axle 6 of the maintaining part 4 of the 31b of cutter head portion, stopper 32 is installed regularly, and inserts the iron coil bobbin (bobbin) 33 that slides freely on 6 at this, these axle 6 upper ends are screwed on below the magnet 34.
