The line of the 4th receiving point 34, the 5th receiving point 35 and the 6th receiving point 36 is vertical direction, and three protects in constituting
Shield area 200, the bending working region of correspondence protection bender, the domain of middle protection zone 200 is mainly protected the position of point of a knife, is prevented and it
He collides at barrier 8, and the hand drop-in of main protection people is in position of tool tip；
And, the line of the 4th receiving point 34, the 5th receiving point 35 and the 6th receiving point 36, apart from bending line 2mm backward,
At this moment because prevented during box is rolled over remaining side it is too early block a little the 4th receiving point 34, the 5th receiving point 35 and the
Six receiving points 36 cause the stopping downward actuation of machine；
The line of the 7th receiving point 37, the 8th receiving point 38 and the 9th receiving point 39 is vertical direction, and three protects before constituting
Shield area 300, the front portion of correspondence protection bender bending working region, the hand of main protection people is possible to when metal plate is captured

Ensure position at least 2mm of the 4th receiving point 34 apart from the point of a knife of mold 6.4th receiving point 34 to the 6th connects
Sink 36 is a safe distance for regulation, and mechanical stop distance should be less than safe distance.Mechanical stop distance is bender
One performance parameter of machine.The generation of mechanical stop distance is because upper beam is during moving downward, when upper beam is transported downwards
After dynamic signal stops, because upper beam has certain inertia, controller has certain response time, also by the machinery of lathe
The combined influence of characteristic and hydraulic characteristic, upper beam may proceed to stop after declining a small distance, and this small distance is used as machinery
Stop distance.
The efficient bender safe light curtain that the present invention is provided, the launch point positioned at different protection zones can be relatively independent
Shielded, i.e., rear protection zone 100, middle protection zone 200 and preceding protection zone 300 can be shielded respectively；According to rear protection zone 100,
Middle protection zone 200 is different with the state that preceding protection zone 300 is shielded, the efficient bender safe light curtain that the present invention is provided, can
To there is three mode of operations.
First mode of operation：It is in the case of general bending, i.e., preceding when bending workpieces 5 are a flat board metal plate refering to Fig. 4
Protection zone 300, the trizonal launch point in middle protection zone 200 and rear protection zone 100 are not shielded.
Second mode of operation：Refering to Fig. 5, when during box is rolled over, if treating structure such as Fig. 5 institutes of bending workpieces 5
Show, then in normal bending because rear baffle 4 needs to move to the lower section for relativelying close to the 3rd receiving point 33, in order to avoid machine
Device hang-up is, it is necessary to protection zone 100 after shielding；In normal bending because the flanging of box is under the 9th receiving point 39
Side, in order to avoid machine hang-up, in addition it is also necessary to shield preceding protection zone 300.
3rd mode of operation：Refering to Fig. 6, during box is rolled over, if treat bending workpieces 5 structure as shown in fig. 6,
Rear baffle 4 needs to move to the lower section of the 3rd receiving point 33, does not have the flanging of metal plate in the lower section of the 9th receiving point 39, then only
Mask rear protection zone 100, middle protection zone 200 and the normal work of preceding protection zone 300.
Compared to the efficient bender safe light curtain that prior art, the present invention are provided, multiple launch points are protected before constituting
Area 300, middle protection zone 200 and the different protection zone in rear protection zone 100 3, it acts on position and corresponds to bender bending respectively
Three part before, during and after region；By shielding the launch point in different protection zones, various protected modes can be converted, to tackle
Requirement and safeguard protection of the bending operation of different situations to realize different bending operating modes are acted on.
Particular, it is important that A protection zones 400, B protection zones 500 and C protection zones 600 can also be shielded respectively, this is relied on
Design, is capable of achieving instant function of shielding, and lower mask body introduces the instant function of shielding.
Before instant function of shielding is introduced, first (key point is referred both to some key points of definition bender upper beam action
Position of tool tip), and between the position of difference, the control mode of safe light curtain.
Key point is from top to bottom followed successively by：PMS is top dead-centre, is the extreme higher position of the artificial upper beam motion for setting；PCV
That is rate conversion point, in this segment distance of PMS to PCV, upper beam is rapid decrease motion, and the speed for reaching upper beam after PCV starts
It is slack-off；PMI is bottom dead centre, is the extreme lower position that upper beam can decline.
Between 2 points of PMS to PCV, upper beam is quick motion downwards.At this moment safe light curtain shields, and prevents
Only collided with other barriers 8 because of mould point of a knife on upper beam during rapid decrease and cause unexpected injury；Arrived in PCV
The distance between PMI, upper beam is downward microinching, and this when, safe light curtain was inoperative.
Because the 4th receiving point 34 to the distance of the 6th receiving point 36 is a safe distance, the machinery stopping of acquiescence machine
Distance is less than safe distance.So the installation site requirement of safe light curtain is the 4th receiving point 34 apart from upper mould point of a knife 2mm.Ensure
During quick motion downwards, if the 6th receiving point 36 detects the signal that upper beam after barrier 8 moves downward and stops
Stop, because upper beam has certain inertia, controller has certain response time, also special by the mechanical property and hydraulic pressure of lathe
Property combined influence, upper beam may proceed to stop after declining a small distance, and the distance of point of a knife and barrier 8 is at least 2mm, it is ensured that
Safety.PCV, due to there is the instant function of shielding of normal bending, can be set PCV to metal plate to the distance of sheet metal work 5 simultaneously
The position of golden top 2mm.
Instant function of shielding, principle is as follows：
As shown in fig. 7, when safe light curtain follows upper beam when moving downward the fast next stage, when receiving point is due to barrier 8
When stopping light and do not receive light, now safe light curtain can cut off downstream signal, and upper beam can continue to move downward
Stopped after one mechanical stop distance.
If moved downward, to the 6th receiving point 36 at the position of workpiece 5, because workpiece 5 obstructs the light, upper beam is still
Can so stop, but could be arranged to the 6th receiving point 36 this when to be blocked in this position is normal condition, light proscenia
The position of automatic record now upper beam motion, while setting the 6th receiving point 36, the 3rd receiving point 33 and the 9th under this position
Receiving point 39 composition the automatic shield of A protection zones 400 fall to detect function, as shown in Figure 8.So after first time is set, with
Afterwards for thickness of the same race the bending of workpiece 5, upper beam when the 6th receiving point 36 is moved in 5 position of workpiece, due to A protection zones
400 automatic shields, so do not result in upper beam motion stopping, upper beam may proceed to move downward.
Similarly, when upper beam moves to B protection zones 500 close to workpiece 5 for the first time, it is also possible to carry out same record
Automatic shield function behind position, as shown in figure 9, later upper beam moves to three of automatic shield B protection zones 500 behind this position
Receiving point, upper beam continues sharp downward movement.
Similarly, when upper beam moves to C protection zones 600 close to workpiece 5, due to introducing rate conversion point PVC before
At least provided with 2mm, that is, now the position of the 4th receiving point 34 is exactly the position of rate conversion point PVC, as shown in Figure 10, this
Shi Shangliang movement velocitys by change under fast it is slow under.The safe light curtain failure under the slow next stage.
Upper beam point of a knife apart from least position of 2mm of workpiece 5 start it is slow under, this actually shorten it is slow it is lower to bending away from
From, process time is shortened, improve production efficiency.
This function ensure that when upper beam point of a knife reaches PCV, although receiving point below metal plate, but
Still machine will not be caused to stop, at utmost shortening PCV to PMI distances, in fact, rate conversion point minimum can be set
To 2mm, production efficiency is greatly improved.
Except outside above-mentioned position, shielding respective regions, receiving point detects barrier 8 still in other positions
Upper beam motor message can be cut off stops upper beam, as shown in figure 11.
