The side of 8e1 is provided with guide holder 8e2, and front sides of the guide holder 8e2 far from stamping station 8 is symmetrical arranged there are two bending bar 8e3, and two
A bending bar 8e3 runs through guide holder 8e2 in horizontal, and bending bar 8e3 coordinates with guide holder 8e2 horizontal anomalous movements, two bending bars
The bottom of 8e3 offers tooth socket, and the two is respectively arranged below with a gear, two gears with power motor 8e1
Spindle drive connection, the outside of stamping station 8 is symmetrically opened up crosses slot 8e4 there are two bending, and two bendings cross slot 8e4 and bending
Connection in chamber 8b, two front ends of the bending bar 8e3 far from guide holder 8e2 are able to movable be plugged in a bending and cross slot
In 8e4.After the sheet metal 12 being punched is headed by material ejection cylinder 9 to bending chamber 8b, at this time two bending bar 8e3 by
The cooperation of power motor 8e1 and gear, two bending bar 8e3 cross slot 8e4 into bending chamber 8b by bending and move, and roll over
Curved bar 8e3 crosses the movement that slot 8e4 can be more stable by guide holder 8e2 and bending.
The bending force piece further includes two tension springs, and one end of two tension springs is connect with the top of guide holder 8e2, and two
The other end of a tension spring is connect with the top in two stage casings bending bar 8e3 respectively.In the 8e3 movements of bending bar, tension spring can be relied on
Active force, realization that can be more stable translate.
The bending accessory part packet assistant cylinder 9d and u-bracket 9e being arranged on assistant cylinder 9d output ends, it is U-shaped
The opening of holder 9e is facing towards the bottom of stamping station 8, and the bottom of stamping station 8 is offered for u-bracket 9e opening both ends energy
Enough vertical movable two traveling slots, two traveling slots are connected to in bending chamber 8b, through assistant cylinder 9d driving u-brackets 9e
Opening both ends it is movable into bending chamber 8b by traveling slot.In the 8e3 movements of bending bar, u-bracket 9e is by assistant cylinder at this time
The work of 9d and move, and its both ends that are open moves in traveling slot, that is, by 12 meeting of sheet metal in bending chamber 8b
Its corresponding part in aperture position both ends is pushed up upward, then coordinates the front end propulsive force of bending bar 8e3 so that 12 quilt of sheet metal
The part that u-bracket 9e openings both ends jack up is bent over bar 8e3 and heads on again, realizes bending.
The foldable component includes bending cylinder 7k and compact heap 7m, and bending cylinder 7k is arranged in inversion on the top of footstock
Portion, offer on footstock for bending cylinder 7k piston rod can by the second unthreaded hole, compact heap 7m is located at the lower section of footstock,
And it connect with the piston rod of bending cylinder 7k, advances into bending chamber 8b through bending cylinder 7k drivings compact heap 7m.Due to U
After type holder 9e jacks up sheet metal 12, bending cylinder 7k is moved synchronously, and compact heap 7m is poured to bending chamber 8b,
Sheet metal 12 in bending chamber 8b is compressed, compact heap 7m may be constructed rectangle knot with u-bracket 9e opening both ends splits
Structure, then the structure of compact heap 7m i.e. stepped, can evade falling u-bracket 9e openings both ends, while u-bracket 9e fortune
In dynamic, sheet metal 12 can not only be compacted to the part that block 7m is pushed down and jacked up yet, last compact heap 7m can rise reset, and
And u-bracket 9e also resets, last bending bar 8e3 ejects the shrapnel 13 after bending, so 8 back side of stamping station can be provided with out
It is connected in material mouth 10, discharge port 10 and bending chamber 8b.
Operation principle：Manipulator is one by one by sheet metal 11 in lying in a horizontal plane on transfer feed bin 1, then by feeding cylinder
2 piston motion, and coordinate scraping wings 2a so that the sheet metal 11 is pushed on two pressing blocks, and lifts electricity
Bar 1c is slowly declined with block 1e is lifted so that lift block 1e cooperation feeding cylinder 2, purpose allow lift it is final on block 1e
Multiple sheet metals 11 are piled up in superposition, are piled up to a greater number, are lifted electric pole 1c and slowly move, output rod can will lift block
1e is slowly lifted, and the sheet metal 11 of top takes the lead in close to travel wheel 3b, and travel wheel 3b is at this time by traveling motor 3a works
It rotates, and rotates and generate friction with sheet metal 11 so that the sheet metal 11 is driven by friction, then sheet metal 11
It being driven into two mounting plate 4a, top takes the lead in passing through from anti-wheel lower section of sticking up, if sheet metal 11 upwarps,
Roller contact is upwarped by this, and corrects limit, then sheet metal 11 enters between two power roller 4c, and dynamic by one
The rotation of power roller 4c, in cooperation travel wheel 3b so that the sheet metal 11 is smoothly by several friction roller 4e, subsequently into extremely
Two are corrected in disk 4m, and the side of sheet metal 11, which can contact, corrects disk 4m, and carries out friction transition by correction cambered surface 4m1,
So that sheet metal 11 is in a posture being previously set and enters in stamping station 8, wait for that sheet metal 11 delays in stamping station 8
It is slow mobile, and after reaching below punching cylinder 7a, the piston of punching cylinder 7a declines so that rectangular slab 7b declines, then in advance
Casting die takes the lead in 11 surface of contacting metal thin plate, and simultaneously, the piston of lower die cylinder 9b pushes up upward, by lower module 9c head into
It is punched in chamber 8a so that then the end face of the end faces lower module 9c and stamping station 8 coordinates punching cutter 7e to be punched into metal
Thin slice 12, then lower die cylinder 9b piston resets are entered to sheet metal 12 in punching chamber 8a by lower module 9c, and
And material ejection cylinder 9 relies on die pad 9a at this time, which is headed into bending chamber 8b, at this time two bendings
With power motor 8e1 and gear, two bending bar 8e3 cross slot 8e4 into bending chamber 8b by bending and move bar 8e3,
U-bracket 9e is moved by the work of assistant cylinder 9d at this time, and its both ends that are open moves in traveling slot, while bending gas
Cylinder 7k is moved synchronously, and compact heap 7m is poured to bending chamber 8b, is compressed to the sheet metal 12 in bending chamber 8b, pressure
Tight block 7m may be constructed rectangular configuration with u-bracket 9e opening both ends splits, and due to the setting of compact heap 7m, u-bracket 9e is only
The part that can avoid sheet metal 12 and compact heap 7m, which rises, to be jacked up, and the front end propulsive force of bending bar 8e3 is then coordinated,
It is headed on so that sheet metal 12 is bent over bar 8e3 again by the part that u-bracket 9e openings both ends jack up, realizes bending, wait for metal
After thin plate 11 is punched, the waste material of both sides can take turns 6a by way of drawing, and draw wheel 6a and be worked by servo motor 6b, by this
Waste material is smoothly drawn, and after waste material is brought out wheel 6a extractions, can be taken and be fallen on lifter plate 6d, lifter plate 6d can decline so that this is useless
Material slowly landing, waits for manually focusing on.
The above described is only a preferred embodiment of the present invention, not making any limit to the technical scope of the present invention
System, thus it is every according to the technical essence of the invention to any subtle modifications, equivalent variations and modifications made by above example,
In the range of still falling within technical scheme of the present invention.
