Specific embodiment
The present invention is as Figure 1-10 shows, and the Bending Mould includes upper die holder 1, cope plate 2, lower die 3, lower die holder 4 and extremely
A few bending punching pin 5, the lower die are fixedly connected on the top surface of lower die holder, and the cope plate is liftable set on lower die
Top, the liftable top set on cope plate of the upper die holder, the bending punching pin are removably attachable to the bottom of upper die holder
On face and its length is greater than the thickness of cope plate, offers at least one accommodating being adapted to bending punching pin on the cope plate
Hole；As Figure 8-9, workpiece is pushed down with lower die cooperation in use, cope plate downlink can be controlled first, then controls upper die holder downlink,
So that bending punching pin is extended downwardly along accommodating hole, finally cooperate bending workpieces with lower die；The bending punching pin 5 is towards lower die 3
It opens up jagged at the root edge of side, idler wheel 6 is hinged in the notch.
People also found in actual use, since idler wheel belongs to stressed member, need to carry out more after a certain period of use time
When changing, and traditional articulated form will bring great trouble to the replacement of idler wheel, and substantially extending replacing construction and stop work
Between, so that finally strong influence is brought to the process-cycle of workpiece, in this regard, this case is also made that following optimal enforcement side
Formula.
The bending punching pin 5 includes ontology 51, fixing clip 52 and movable clip block 53, and the ontology 51 can by bolt one
Disassembly is connected on the bottom surface of upper die holder 1, and the fixing clip 52 is fixedly connected on ontology 51 towards 3 position of lower die
On side surface, the movable clip block 53 fit in ontology 51 towards on the side surface of 3 position of lower die and with fixing clip 52
Removably it is connected by least two bolts two；
The bottom of end face of the fixing clip 52 towards movable clip block 53 offers accommodation groove 1, the activity folder
The bottom of block 53 towards the end face of fixing clip 52 offers accommodation groove 2 530；Institute is formed by accommodation groove one, the combination of accommodation groove two
State notch；
The grafting cylinder 60 being linked together with it, one 520 direction of accommodation groove are equipped on the both sides of the face of the idler wheel 6
Offer the arc groove 1 being adapted to grafting cylinder 60 on the surface of movable clip block 53, the accommodation groove 2 530 is towards fixing clamp
The arc groove two being adapted to grafting cylinder 60 is offered on the surface of block 52, the two grafting cylinders 60 are plugged on arc groove one respectively
521, in arc groove two.In this way, realize the hinged of idler wheel and bending punching pin, so that idler wheel cocoa freedom and fixing clip,
Movable clip block does relative rotary motion.
And when roller surface appearance abrasion, slight crack etc., when needing to replace idler wheel, can first it remove in fixing clip
Bolt two so that fixing clip is separated with movable clip block, then extracts idler wheel out；Hereafter, new, the intact rolling of operator desirable one
The grafting cylinder of one side is inserted into accommodation groove one, then accommodation groove two is directed at another grafting cylinder by wheel, finally, bolt two is loaded onto,
So that grafting cylinder enters in accommodation groove two, and movable clip block and fixing clip are relatively fixed.The replacement process of entire idler wheel
It is very convenient and extremely short to the replacement cycle of idler wheel, downtime period is effectively reduced to a certain extent, is improved to workpiece
Processing efficiency.
The arc groove one and arc groove two is concentric and the two is in major arc shape.Ensure that idler wheel can be stable
It is rotated freely around Pivot Point Center, and passes through the structural form of major arc shape, so that the stability of idler wheel is further promoted.
Plane bearing 61 is equipped in the two grafting cylinders 60, a side end face of the plane bearing 61 is against idler wheel
On end face and another side end face is against on the surface of accommodation groove one or accommodation groove two.To guarantee that idler wheel is stable, alters without axial
While dynamic so that idler wheel can freely, smooth do relative rotary motion with fixing clip, movable clip block.
