Description

Swan neck system in multimode bending machine

Technical field

The present invention relates to the swan neck systems in bending machine more particularly to multimode bending machine.

Background technique

Multimode bending machine is a kind of tubing that a straight tube can be bent into the bend pipe with multiple and different bending radius Process equipment.Multimode bending machine includes: rack, is provided with the feeding mechanism and swan neck system for capableing of conveying pipe on the rack, The swan neck system includes: the headstock being connected with rack, is vertically arranged with hydraulic cylinder, the work on hydraulic cylinder on the rack Stopper rod is connected with headstock, and by driving, piston rod stretches out hydraulic cylinder upwards or retracted downward can make headstock on the rack It rises or falls, main shaft is provided in headstock, closed assembly has the wheel model of several different specification sizes on main shaft, on main shaft It is fixedly connected with bending pipe arm, closed assembly has the clamping being adapted to one by one with each wheel model respectively on bending pipe arm.During Bending Processing, First on tubing to be curved is fed forward between the wheel model and clamping in headstock by feeding mechanism to bight portion, then basis Processing request starting hydraulic cylinder driving headstock is moved upwardly or downwardly, make on headstock corresponding a pair of wheel model and clamping with The first section aligned to be curved on tubing to be curved, this can carry out bending to bight portion to first after molding to wheel model and clamping, After the completion of bending, this moves back mould to wheel model and clamping, and feeding mechanism continues forward to convey tubing to be curved, make first to bight portion from Wheel model and clamping are opened, until second on tubing to be curved enters between wheel model and clamping to bight portion, then starts hydraulic oil Cylinder driving headstock is moved upwardly or downwardly, and makes second on headstock in corresponding another pair wheel model and clamping and tubing to be curved Section aligned to be curved, this to wheel model and clamping molding after can to second to bight portion carry out bending, after the completion of bending, wheel model with Mould is moved back in clamping, and feeding mechanism continues to be fed forward tubing to be curved, repeats above-mentioned bend pipe procedure of processing, until tubing to be curved is according to adding Work requires and is respectively the bend pipe with multiple and different bending radius by the wheel model of different specification size and clamping bending and molding.On Swan neck system is stated to have the following deficiencies: 1, the hydraulic cylinder of headstock is driven to be constantly subjected to headstock and be mounted on headstock Wheel model and the downward pressure of clamping are easy for keeping the hydraulic cylinder impaired in this way, to can not work normally, or even be easy to happen Production accident；2, feeding mechanism is in conveying pipe, and the middle section of tubing is because the influence of self weight is easily bent downwardly deformation, in this way During feeding forward, tubing is easy to produce drift and shakes, it is difficult to accurate to reach corresponding wheel model and folder in swan neck system Between mould, it is often necessary to which artificial progress auxiliary operation, which just can ensure that, moves to tubing between corresponding wheel model and clamping, thus The working efficiency of bend pipe is reduced, and is easy to influence the quality of bend pipe product；3, the clamping being fixed on bending pipe arm is being closed It is horizontally moved always along horizontal guide rail during mould and demoulding, so that clamping is still located on and wheel model phase after demoulding Level position, in this way during carrying out continuous bending processing to tubing, when needing to be overturn tubing, tubing Upper machined molding bending part is easy for colliding with clamping, at this moment with regard to usually needing manually to be interfered, drops significantly Low bend pipe efficiency if worker operation is improper is also easy to that tubing is made to collide with clamping, and the tube surfaces after collision will be sent out Raw recess or deformation, to influence the quality of final bend pipe product.
