[specific embodiment]
Below in conjunction with accompanying drawing, the utility model is further described:
A kind of safety guard of bender; comprise the installing plate 2 being fixedly connected with bender frame 1; described installing plate 2 is provided with the support 3 that can rotate to it; described support 3 is provided with and can detects the photoelectric sensor switch 4 that stretches into the finger in bending machine die, is also provided with first positive stop 5 of in the time that described support 3 turns to detection position, described support 3 being located on described installing plate 2.Photoelectric sensor switch 4 can detect the workman's finger or the arm that extend in bending machine die, once finger or arm stretch between upper/lower die, photoelectric sensor switch 4 will send signal, and bender is shut down, and therefore, has guaranteed workman's safety.Support 3 can rotate relative to installing plate 2, can in replacing bending machine die, be that mould is stepped down, and makes the direct labor can quickly replacing mould.The first positive stop 5 can make its relevant position that remains on setting can make each swinging mounting 3 to detection position time, and does not need time time adjustment, has improved efficiency.Described installing plate 2 comprises starting stave 21 and the second riser 22, between described starting stave 21 and the second riser 22, be provided with the transverse slat 23 that connects the two, described starting stave 21 is fixedly connected with described frame 1, and the second described riser 22 is hinged with described support 3.Described installing plate 2 is one-body molded.One-body molded processing is simple, convenient.
On the second described riser 22, be also provided with second positive stop 6 of in the time that described support 3 rotates away from its detection position, described support 3 being located.In the time changing the mould of bender, swinging mounting 3, is pull from the side and dismantles mould and step down.The second positive stop 6 is set and can makes support 3 be parked in the position of setting, avoid support 3 in the situation that rotation amplitude is excessive, to break the holding wire of photoelectric sensor switch 4, after also having prevented from rotating, can not locate and occur rocking and damage photoelectric sensor switch 4.
On described transverse slat 23, offer horizontal transverse slat bar hole 231, on the first described positive stop 5, offer the first bar hole 51, in described transverse slat bar hole 231 and the first described bar hole 51, be provided with the first described positive stop 5 is locked to the first lock(ing) bolt 7 on described transverse slat 23.On the second described riser 22, offer vertical riser bar hole 221, on the second described positive stop 6, offer the second bar hole 61, in described riser bar hole 221 and the second described bar hole 61, be provided with the second described positive stop 6 is locked to the second lock(ing) bolt 8 on the second described riser 22.Described transverse slat bar hole 231 is two, and the first described bar hole 51 is two, and the first described lock(ing) bolt 7 is two, and is arranged in described transverse slat bar hole 231 and described the first bar hole 51.Described support 3 comprises the support riser 31 hinged with described installing plate 2 and is 90 ° of support transverse slats 32 that are connected with described support riser 31, on the support transverse slat 32 described in described checkout gear 4 is fixedly connected on.On described support transverse slat 32, offer support bar hole 321, in described support bar hole 321, be provided with described checkout gear 4 is locked to the 3rd lock(ing) bolt 9 on described support transverse slat 32.The effect that bar hole is set is to finely tune according to the needs of actual conditions the position of incline the first positive stop 5, the second positive stop 6 and photoelectric sensor switch 4, guarantees precision.
Described installing plate 2 is one-body molded.Installing plate 2 adopts the one-body molded processing of bender, easy to process, manufactures efficiency high.
Operation principle:
In the time that workman carries out work; first swinging mounting 3; support 3 is resisted against on the first positive stop 5; now support 3 and photoelectric sensor switch 4 mounted thereto are just in operating position; can detect because workman extend into finger or the arm between upper die of bending machine tool 10 and bed die 11 because of carelessness; once photoelectric sensor switch 4 detects the finger or the arm that there are human body between mold 10 and bed die 11; photoelectric sensor switch 4 just sends signal to bender control system, is shut down by control system control bender.Like this, just avoid mold 10 and bed die 11 to jam a finger or (as shown in Figure 4) occurs the situation of arm.
Because the replacing of the upper/lower die of bender need to split out from the side of bender by mold 10 and bed die 11, will cause and stop interference mold exchange more if support 3 is resisted against on the first positive stop 5, just mould can not be taken apart.At this moment only need swinging mounting 3, make the lower end abutment of support 3 on the second positive stop 6, so just mould can be pulled down from the side (as shown in Figure 3).
