Description
Technical field
The present invention relates to bending machine, and in particular to the swan neck system in bending machine.
Background technology
The structure of the swan neck system used in bending machine is at present：Including frame, the vertical branch of activity in the front end of frame
The main shaft that top is provided with wheel model is held, main shaft is driven by drive mechanism and rotated, and fixed cover is equipped with bending pipe arm on main shaft, in bend pipe
Horizontal guide rail is provided with the top of arm, the clamping for being provided with and tubing being matched for clamping tightly with wheel model, clamping are slided on horizontal guide rail
Along horizontal guide rail closer or far from wheel model under the driving for the clamping cylinder being installed on bending pipe arm.The work of above-mentioned swan neck system
Process is：In an initial condition, bending pipe arm is in clamping station；During bend pipe, one end of tubing to be curved is first positioned over bending machine
In feed mechanism, then the other end of tubing to be curved is placed between wheel model and clamping, then starts clamping cylinder, until folder
Locking oil cylinder promotes clamping to be moved to along horizontal guide rail, then stops clamping cylinder
Action, be then again turned out drive mechanism drive shaft, synchronous drive wheel model and bending pipe arm are turned out, and bending pipe arm exists
Meeting synchronous drive clamping is turned out during being turned out, and makes wheel model and clamping synchronous axial system, so as to by clamping and take turns
The tight bending pipes shaping of die clamp, until after bending pipes to be curved shaping, then stop main axis, then restart clamping oil
Cylinder, promote clamping along horizontal guide rail away from wheel model, so as to unclamp the tubing by clamping and wheel model clamping, then worker again will bending
The tubing of shaping takes out from wheel model, then drive mechanism drive shaft is inwardly turned round again, synchronous drive wheel model, bending pipe arm and
Clamping inwardly returns back to clamping station, carries out bend pipe next time and operates.The shortcomings that above-mentioned swan neck system is：（1）Bending pipes into
After type, the molded tubing to be removed being stuck in wheel model is damaged to avoid wheel model from rotating, now wheel model should stop operating, and lead
Cause bending pipe arm to be rotated further, the molded tubing that worker station will be stuck in wheel model in the turning circle of bending pipe arm can only be treated
After taking-up, then drive mechanism can be made inwardly to return back to clamping station by main shaft synchronous drive wheel model, bending pipe arm and clamping, due to
Worker stands in the turning circle of bending pipe arm all the time during tubing is taken, when worker is during tubing is taken, because worker grasps
Slip up or to the drive mechanism that drive shaft rotates break down etc. reason cause bend pipe revolution of arm when, worker easily by
The bending pipe arm inwardly turned round is injured, and security is low, and huge hidden danger has been buried for production safety；（2）One when tubing is to be curved
Bend pipe operation is completed, it is necessary to the next when bent portion position carries out bend pipe operation of the root tubing, if two are treated in pipe portion position
When the distance between bend pipe position is more than the translating stroke of clamping, tubing will be by during being fed mechanism and moving forward
Clamping stops so that tubing treats that bent portion position can not reach clamping station, so as to which bend pipe operation can not be continued, and greatly limitation
The scope of application of bending machine.

Quan Xing；
The operation principle of the present invention is as follows：
In an initial condition, bending pipe arm 4 is located at clamping station, now the keyway phase of the slotting key 8 on sliding block 6 and positioning disk 9
Depart from；During bend pipe, first tubing to be curved is placed in the die cavity of wheel model 2, then makes the piston rod of clamping cylinder 18 protruding,
The folder that clamping cylinder 18 is moved inwardly on sliding block 6 by the promotion sliding block 6 of the connection of first connecting rod 19 and second 20 along horizontal guide rail 5
Mould 7 is in that relative clamping shape clamps tubing to be curved with wheel model 2, and now, the slotting key 8 of sliding block outer end just inserts the key of positioning disk 9
Groove, bending pipe arm 4 and the phase of main shaft 3 are fixed；Then the piston rod of bend pipe oil cylinder 14 is made inwardly to retract, bend pipe oil cylinder 14 passes through chain
13rd, the mutual cooperation of driven sprocket 12 and drive sprocket 10 drives main shaft 3 to be turned out clockwise, the synchronous drive wheel model of main shaft 3
2nd, the clamping 7 on bending pipe arm 4 and bending pipe arm 4 is turned out clockwise, so that clamping 7 enters tubing in clamping shape with wheel model 2
Row bending, bend pipe angle is needed when encoder 24 detects that main shaft 3 turns to by the cooperation of the gear 26 of second gear 25 and the 3rd
Afterwards, stop the action of bend pipe oil cylinder 14, now, shaping is bent by the tubing clamped by clamping 7 and wheel model 2, and in bend pipe
Arm 4 clockwise be turned out during, bending pipe arm 4 can by the cooperation of the rack 17 of first gear 15 and first of its bottom,
Make the piston rod of bending pipe arm angling cylinder 16 is synchronous to pull out to stretching；After bending pipes to be curved are molded, then make clamping cylinder 18
Piston rod is inwardly retracted, and clamping cylinder 18 is outwards put down by the promotion sliding block 6 of the connection of first connecting rod 19 and second 20 along horizontal guide rail 5
The tubing of brake forming is just unclamped in the clamping 7 moved on sliding block 6, and now the slotting key 8 of sliding block outer end just leaves positioning
The keyway of disk 9, the relative main 3 of bending pipe arm 4 is freely rotated, then make the piston rod of bending pipe arm angling cylinder 16 to inside contracting
Return, bending pipe arm angling cylinder 16 drives the inwardly revolution counterclockwise of bending pipe arm 4 by the cooperation of the first rack 17 and first gear 15
To clamping station, then worker is again by the tubing taking-up for the brake forming being stuck in wheel model 2.It is an advantage of the invention that：
（1）Because worker is when taking brake forming tubing, bending pipe arm has returned back to clamping station so that worker will not be located at bend pipe again
The turning circle of arm, so that the occurrence of bend pipe revolution of arm injures worker when effectively preventing from taking pipe, substantially increases using peace
Quan Xing；（2）After completing bend pipe operation to a position to be curved of tubing due to bending pipe arm, clamping station can be first returned back to, so as to
Effectively prevent the clamping of bending pipe arm from interfering the feeding of tubing, so as to substantially increase the scope of application of bending machine.
