CNC sheet bending machine is usually used steel welded structure, with ample strength and rigidity. Hydraulic drive, cylinder disposed on each ends of the machine slider, direct drive slide work. Slide synchronization mechanism adopts torsion bar forced synchronization. Mechanical stopper structure, stable and reliable. Slide stroke motor quick tune, manual standardization, the counter show. Wedge-type deflection compensation mechanism, so as to ensure a high bending accuracy. CNC sheet bending machine 3 common structure kind as follows:
Acting on a slider that's driven downward movement of the punch. so as to confirm the slider once operating stroke and come, not owing to the slider face up to partial load and round the cylinder pipe resistance distinction caused slider inclined with relation to the table, so poignant the standard of the piece of work forming, typically equipped with slide motion synchronous system. The acting is straightforward with mechanical or hydraulic synchronization system. Mechanical synchronization device of easy structure, low cost, and might get some synchronization accuracy, however less ready to face up to partial load, and so solely appropriate for tiny and medium sized hydraulic plate bending machine. Hydraulic synchronization system with a mechanical hydraulic servo synchronization system, electro-hydraulic servo synchronization system associated an electronic digital valve management synchronous system. Such synchronization system high synchronization accuracy, suited to high bending exactitude sheet bending machine. however the technical complexness and high value.
By acting that's put in within the lower portion of the machine slide, and junction rectifier the upward movement of the die. operative cylinder disposed during a central position slider, nominal force-hour single-cylinder, three-cylinder nominal force is giant. As a results of the central fuel tank centered on the slider, the slider is per the beam deformation, the gap between the punch and die a lot of equally on the block length, that the higher the piece of work bending exactitude. Slider come by gravity, so the mechanism is straightforward. Acting beneath the advantage of sunshine weight, compact structure, straightforward maintenance; disadvantage is synchronization accuracy isn't high; single-acting cast tilt solve troublesome problems; precise management of the depth of the punch into the die is difficult; not offered for punching; and work bench to run up the die with the piece of work, the operator isn't straightforward to work.
Three folding-type add the preceding three-point bending technique works, 3 bender advantage is that the high bending exactitude, wide craft use, and has had four sides forming machine functions. however the machine structure is difficult and dear, the present worth is comparable to doubly the movable kind two-axis CNC sheet bending machine.
