NC BENDING MACHINES WITH FEEDER

Similarly to standard NC semi-automatic benders, the versions with the feeder are excellent in plants of medium production load. Additionally, because of the fact that the bender is equipped in a feeder with the rotation servomechanism, the models may be successfully used for complicated spatial bending. With applicable configuration of the equipment, they allow for obtaining high quality of bending for thin-walled pipes and sections and with small radii. The model range covers with standard NC semi-automatic benders, that is from the model for bending pipes with the maximum diameter of Ø38mm to benders with the bending efficiency up to max. Ø325mm.

The most important functions and advantages:

• all working motions, with the exception of feeder rotation, are realized with the help of central hydraulic system equipped in oil control and cooling system,
• the feeder rotation is realized with the use of servomechanism programmed from the central control panel,
• the operator is responsible only for moving the cart with the feeder in accordance with the previously set stoppers, the rotation is carried out automatically as set in the programme,
• control takes place with the use of operation panel (Polish) with the possibility of saving up to 200 processing programmes with 10 bends of various angles each,
• the standard equipment of the machine comprises the guide mould stroke servomotor (the so-called booster), arms which reinforce the shaft with the bending and guide mould clamp, controlled mandrel return and reverse bending function
• possibility of modification in terms of the mandrel working length, bending header size, etc.  

When selecting the machine, it is worth to pay attention to the very essential fact concerning the role and involvement of the operator in the material bending process. As far as the discussed NC semi-automatic mandrel benders with the feeder are concerned, the operator is responsible only for the material shift between the given bends. The control over the applicable material shift is made easier due to the list with the measure which at the same time guarantees the production repeatability. The change of the bending plane is realized automatically due to the rotation of the servomechanism driven feeder. The offer comprises, both basic versions of NC semi-automatic benders, in which the material shift and rotation is carried out manually by the operator as well as CNC automatic benders controlled in both axes, where bending takes place without the operator's interference between the given steps.
