In current design considers, in order to easy to control, we are made to the bend pipe work pieces process correspondence of each model
As soon as so may require that and multiple hydraulic cylinders 9 be arranged on the crossbeam 12 of door type frame 8 with hydraulic cylinder 9, and respectively
Multiple oil feed lines 23 are arranged to be respectively controlled.
But the alternative structure of hydraulic cylinder 9 is there are also good various deformation, such as screw-nut transmission, with electric servo cylinder generation
For hydraulic cylinder, with pneumatic cylinder with hydraulic cylinder 9, moving up and down for cambered surface pressing plate 10 is realized using the principle of rodless cylinder.
These modes are all the alternative structures of hydraulic cylinder 9, are the simple deformations of the design, also should be in the protection scope of the design.
Specifically used method:
The application method of the design is described in detail with reference to the accompanying drawings of the specification.It is divided into three steps: one,
Bend pipe workpiece feeding；Two, the retaining wall on slope of feeding back elbow workpiece；Three, the blanking of retaining wall on slope back elbow workpiece.
Before stating three steps on the implementation, for the embodiment of embodiment 1 and embodiment 2, it is also necessary to according to be added
The model of work bend pipe workpiece adjusts 3 position of beveling machine, keeps 3 position of beveling machine and corresponding arc surface base mouth 7 corresponding.But also it wants
The cutter in 3 machining cutter head of beveling machine is adjusted according to the model of bend pipe workpiece to be processed, keeps it straight with bend pipe workpiece to be processed
Diameter is adapted.
For step 1:
It first has to turning to door type frame 8 into Figure of description position shown in FIG. 1, makes mobile column 13 and the right side of door type frame 8
The contact limit of side limited block 16.
Then bend pipe workpiece to be processed is placed on bend pipe support 2 using hanging position it is to be processed.
For step 2:
Bend pipe workpiece is placed on bend pipe support 2 when carrying out retaining wall on slope again, then door type frame 8 is turned to Figure of description
Position shown in Fig. 2 makes the mobile column 13 of door type frame 8 contact limit with left side limited block 15.Then hydraulic cylinder 9 is controlled, is made
The piston rod of hydraulic cylinder 9 extends, and the cambered surface pressing plate 10 of piston rod bottom is pressed on bend pipe workpiece, and bend pipe workpiece is in pressure
Effect is lower to be fixed.Then retaining wall on slope is carried out again.
For step 3:
When after retaining wall on slope to the bend pipe workpiece blanking completed the process, then door type frame 8 turned into Figure of description Fig. 1 institute
The position shown makes the mobile column 13 of door type frame 8 contact limit with right side limited block 16.Then curved by what is completed the process by hanging
Tube workpiece hangs station, with the retaining wall on slope to next bend pipe workpiece.
In summary:
The door type frame 8 of pressing device rotatably opens and closes, so that the bend pipe workpiece in hanging is easily placed into bend pipe branch
It is to be processed on seat 2, enable devices to the processing for being suitable for the large-scale bend pipe double end cut using hanging lifting piece uploading；Bend pipe support
2 are equipped with multiple arc surface base mouths 7, and the corresponding different bend pipe model of each arc surface base mouth 7 is able to carry out a variety of on a station
The bend pipe workpiece double end cut of model is processed, and station is greatly saved to the occupancy of floor space.
