The driving of Fig. 4-Fig. 7 (A)-(J) expression hydraulic type rack and pinion mechanism 16 and relation between the on-off action of a pair of jib 5,5 of cutting knife 4a, 4b is housed.
At first, when cutting knife 4a, 4b were in to greatest extent open mode (starting position), gear 24 was arranged in an end (figure lower end) (Fig. 4 (A)) of tooth bar 25.When this position, crankpin 14 is arranged in rear portion (figure right-hand member).
Then, in case move tooth bar 25 belows to figure as shown in arrow 1,24 of gears are done the inhour rotation shown in arrow m, and crankpin 14 rotates around gear shaft 15, make slide block 10 forwards (left among the figure) (Fig. 4 (B)) move.
So two jibs 5 are pressed the relative direction shown in the arrow n through pitman shaft 8 around jib fulcrum 6 and are rotated, two cutting knife 4a, 4b towards glass blank 30 symmetrically mutually near (Fig. 4 (B)).
And then gear 24 rotations, approaching mutually between two cutting knife 4a, the 4b, glass blank 30 is cut off.Cut off the back under the state that two cutting knife 4a, 4b overlap, gear 24 Rotate 180s ° arrive the middle position (Fig. 4 (C)) of tooth bar 25.This tooth bar middle position is the dead-centre position of cutting knife 4a, 4b, and cutting knife 4a, 4b change to starting from closing action.
In this position, dead point, tooth bar 25 is in the stroke way, and continues straight line in same direction and move.Gear 24 also is in the rotation way in addition, continues to do spinning movement to same sense of rotation.Thereby the reverse position (dead-centre position) in that jib 5,5 opens and closes can not produce the discontinuous point of action because of the collision that stop dog caused as traditional way, can finish the reverse motion of jib in continuous movement process smoothly.
After melten glass (blank) 30 was cut off by cutting knife 4a, 4b, in case gear 24 is crossed the middle position of tooth bar 25, slide block 10 promptly rearward moved, and cutting knife 4a, 4b are to the arrow of opening.Direction moves (Fig. 5 (D)).Because it is not aforesaid switching by forcing to be reversed that the on-off action of this cutting knife 4a, 4b switches, the vibration that causes so move switching.Thereby the crash shock between cutting knife 4a, the 4b can not take place, wearing and tearing, deterioration between cutting knife 4a, 4b or turned etc. can not take place yet, can realize the excellent cutting action.
When gear 24 arrived the other end of tooth bar 25, cutting knife 4a, 4b opened (Fig. 5 (E)) to greatest extent.
At this moment, supply with the melten glass (blank) 30 that next piece need cut off, and change (Fig. 5 (F)) to the return action of tooth bar 25.
That is, from this moment, in case tooth bar 25 moves to the direction (top among the figure) of arrow p, gear 24 is promptly done clockwise rotating shown in the arrow q, and slide block 10 moves on to the place ahead, and cutting knife 4a, 4b move (Fig. 6 (G)) to the arrow r direction of closing.
In case gear 24 arrives the middle position (dead-centre position) of tooth bar 25, cutting knife 4a, 4b promptly close fully, and melten glass (blank) 30 is cut off (Fig. 6 (H)).Reverse motion on this dead-centre position is also same with the locational reverse motion of aforesaid (C) figure, there is not the collision in the tooth bar 25 strokes way, action smoothly can not make cutting knife 4a, 4b bump or vibrates, and can carry out excellent cutting to melten glass (blank) 30.
After melten glass (blank) 30 was cut off by cutting knife 4a, 4b, in case gear 24 is crossed the middle position of tooth bar 25, cutting knife 4a, 4b promptly moved (Fig. 6 (I)) to the arrow s direction of opening.
Then, gear 24 returns the initiating terminal position of tooth bar 25, and cutting knife 4a, 4b become the state of opening to greatest extent (Fig. 7 (J)).That is, return the state of Fig. 4 (A) this moment.
Carry out such operation repeatedly, cutting knife 4a, 4b i.e. order cut off melten glass (blank) 30.
Fig. 9 and Figure 10 are the operation curves of comparison shears of the present invention and traditional shears.
(A) figure be with the action starting point be the total travel curve of benchmark, (B) figure is the details of dead point portion.
In Fig. 9 and Figure 10 (A) figure, longitudinal axis S represent with two cutting knifes between corresponding each the cutting knife distance of distance from the dead point, the longitudinal axis D on right side represents the diameter of blank.In addition, transverse axis is the traveling time of cutting knife, the dead-centre position as 0 point, and as the reference position.
In addition, in (B) figure, the longitudinal axis is represented the miles of relative movement of cutting knife (blade), and transverse axis is represented the traveling time of cutting knife (blade), and time reference point is for moving the zero hour.
The speed v of the blade of a is 2.7m/s among Figure 10 of expression conventional example, and air pressure Pa is 3kg/cm
2, the blade speed v of b is 3.2m/s, air pressure Pa is 4kg/cm
2According to the operation curve of this traditional way, go up because the butt joint of stop dog and mandatory reverse is formed with the interruption action of certain angle at the dead point of cutting knife close moment (D, P), and collision and vibration after the generation cut-out, can produce the skew shown in the oblique line part.C among Figure 10 (B) represents the magnetic valve time of setting up a call that air feed is used.
On the other hand, the blade speed v of representing d among Fig. 9 of the present invention is 4.4m/s, and oil pressure Po is 30kg/cm
2, the blade speed v of e is 5.7m/s, oil pressure Po is 50kg/cm
2, according to operation curve of the present invention, go up the sinusoidal curve that forms slyness at the dead point of cutting knife 4a, 4b close moment (D, P), after cut-out, can not produce collision or vibration.Again, the pressure of blade increases, and speeds up, with shortening duration of contact of blank.For example, when the blank diameter that will cut off was 100mm, T duration of contact of traditional way was about 60-80msec (seeing Figure 10 (A)), and duration of contact of the present invention, T then was about 50-70msec (seeing Fig. 9 (A)), can make that to cut off vestige little and shallow.
Blank diameter is big more, and the effect that shortens duration of contact is obvious more.That is, compare with traditional way, can shorten significantly the duration of contact of major diameter blank.
Fig. 9 (B) expression is worked as oil pressure and is respectively 20kg/cm
2, 30kg/cm
2And 50kg/cm
2The time situation, cut-out power is big more, the speed of blade (response speed) is fast more, and is also short more with the duration of contact of blank.
The present invention avoids bumping and vibrating by adopting hydraulic type rack and pinion mechanism 16, thereby prevents that blade is turned, reduces wear or deterioration, prolongs its work-ing life, can reduce the number of times of maintenance or part exchanging, increases operation rate.Again, can realize high pressure cut-off, can accelerate the speed of cutting knife (blade) 4a, 4b, shorten the duration of contact between blade and blank, make the cut-out vestige little and shallow by oil pressure.And high pressure with combine at a high speed, also can carry out excellent cutting to the major diameter blank.
