Sink 36 is a defined safe distance, 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 be due to upper beam 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 as machinery
Stop distance.
Efficient bender safe light curtain provided by the utility model, the launch point positioned at different protection zones can be relatively only
Vertical is 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
100th, the state that middle protection zone 200 and preceding protection zone 300 are shielded is different, efficient bender safety provided by the utility model
Light curtain, there can be 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, middle protection zone 200 and 100 trizonal launch point of rear protection zone do not shield.
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 be moved to relatively close to the lower section of 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, 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 the structure of bending workpieces 5 as shown in fig. 6,
Rear baffle 4 needs to be moved to the lower section of the 3rd receiving point 33, without metal plate flanging in the lower section of the 9th receiving point 39, then only
Mask rear protection zone 100, middle protection zone 200 and preceding protection zone 300 normal work.
Compared to prior art, efficient bender safe light curtain provided by the utility model, before multiple launch points are formed
Protection zone 300, the different protection zone in middle protection zone 200 and rear protection zone 100 3, it acts on position and corresponds to bender respectively
Three parts before, during and after bending region；By shielding the launch point in different protection zones, a variety of protected modes can be converted, with
The bending operation of different situations is tackled, to realize the requirement of different bending operating modes and safeguard protection effect.
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, can be achieved instant function of shielding, and lower mask body introduces the instant function of shielding.
Before instant function of shielding is introduced, first define bender upper beam action some key points (key point refers both to
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 upper beam motion artificially set；PCV
That is rate conversion point, in this segment distance of PMS to PCV, upper beam is that rapid decrease moves, and the speed of upper beam starts after arrival PCV
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 quickly to move downwards.At this moment safe light curtain shields, and prevents
Only collided because of mould point of a knife on upper beam during rapid decrease with other barriers 8 and cause unexpected injury；Arrived in PCV
The distance between PMI, upper beam are downward microinchings, and this when, safe light curtain was inoperative.
Because the distance of the 4th receiving point 34 to the 6th receiving point 36 is a safe distance, the machinery stopping of machine is given tacit consent to
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 that the signal that upper beam moves downward after barrier 8 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, ensures
Safety.PCV, due to there is the instant function of shielding of normal bending, can set PCV and arrive metal plate to the distance of sheet metal work 5 simultaneously
Golden top 2mm position.
Instant function of shielding, principle are as follows：
As shown in fig. 7, when safe light curtain follows upper beam 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
It 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 curtain device
The position of automatic record now upper beam motion, while the 6th receiving point 36, the 3rd receiving point 33 and the 9th under this position are set
The automatic shield of A protection zones 400 that receiving point 39 forms falls detection function, as shown in Figure 8.So after first time is set, with
The bending of workpiece 5 of thickness of the same race is directed to afterwards, and upper beam is when moving to the 6th receiving point 36 in 5 position of workpiece, due to A protection zones
400 automatic shields, so upper beam motion will not be caused to stop, 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, same record can also be carried out
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 continue 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 rate conversion point PVC position, as shown in Figure 10, this
Shi Shangliang movement velocitys by change under fast it is slow under.Safe light curtain fails under the slow next stage.
Upper beam point of a knife apart from least 2mm position of workpiece 5 start it is slow under, this actually shorten it is slow it is lower to bending away from
From shortening process time, improve production efficiency.
This function ensure that when upper beam point of a knife reaches PCV, although receiving point below metal plate,
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 in above-mentioned position, shielding outside respective regions, receiving point detects barrier 8 still in other positions
Upper beam motor message, which can be cut off, stops upper beam, as shown in figure 11.
