Hidraulic Plate Folding Machine- China Suppliers Factory Manufacturers

CNC press brake is mainly used to realize the bending of metal cabinets, box shells, U-shaped beams and rectangles of various geometric shapes. The plates can be stretched, grooved, punched, and corrugated by the CNC press brake. The CNC press brake processing has the advantages of high bending straightness without marks, peeling or wrinkles.

What is the difference between CNC press brake and electro-hydraulic press brake?

The CNC press brake uses a torsion axis to link the left and right swing rods to form a torsion axis, forcing a synchronization mechanism to move up and down the cylinders on both sides. It is a mechanical forced synchronization method. The parallelism of the slider cannot be automatically checked and adjusted.

The electro-hydraulic press brake installs a magnetic scale on the slider and the wall plate. The numerical control system can analyze the synchronization of the two sides of the slide through the information feedback from the magnetic scale at any time. If something wrong, the numerical control system will be adjusted by a proportional electro-hydraulic servo valve to synchronize the strokes on both sides of the slider. They constitute the feedback closed-loop control of the electro-hydraulic press brake.

The parallelism of the slide block determines the angle of the workpiece. The CNC press brake keeps the slide block synchronized by the machine. There is no real-time error feedback. However, its eccentric load capacity is poor.

The electro-hydraulic press brake is the system through the proportional electro-hydraulic valve group to control the slider synchronization. The magnetic scale reports real-time error.

The CNC press brake does not have a control system and V-axis compensation. You can only stake out and do trial bending first.

The electro-hydraulic press brake is controlled by a professional numerical control system with V-axis compensation. There is a simulated bending function that no stakeout is required.

How to choose a suitable CNC press brake?

When purchasing CNC press brake, consider the production of parts. It must be able to complete the processing tasks. The workbench must be the shortest and the tonnage can be the smallest. The material grade and the maximum processing thickness and length should be paid attention to.

The shorter workbench, the fewer shim adjustments to produce qualified parts. Reduced shim adjustment shortens preparation time.

When free bending is used in CNC press brake, the bending radius is 0.156 times the opening distance of the die. The opening distance of the die should be 8 times the thickness of the metal material. If the bending radius of CNC press brake is almost as small as the material thickness, a bottomed die must be formed.

In order to choose the lowest tonnage specification, it is best to plan for a bending radius larger than the thickness of the material, using the free bending method.

The accuracy is the most important factor affecting your choice. It determines whether you need to consider a CNC or a manual press brake. If the bending accuracy requires within 1° and cannot be changed, you must focus on the CNC press brake.

How to improve the lifespan of CNC press brake?

Create a uniformly distributed machining allowance for each type of bending in each bending process. The main CNC press brake mold should be as close as possible to the final shape of the mold in each process.

The evenly distributed machining allowance of the CNC press brake mold ensures a constant and high productivity and a safe bending process. When the angle is constant, the bending speed and feed rate can also be kept constant at a high level.

Continuous cutting of CNC press brake should be maintained for as long as possible during the bending process. Otherwise, it will increase the thermal stress and thermal fatigue on the cutting edge. A uniform and high temperature in the cutting area is more beneficial.

LZK has introduced Ulti-Form, a new robotic bending system with an automatic tool changer bender. Ulti-Form follows the success of LZK's Dyna-Cell robotic bending cell and takes automated bending technology a step further by incorporating an automatic tool changer to keep bending productivity at the highest level, efficiently handling small batches and long production runs with minimal changeover time. Ulti-Form achieves high productivity bending through unattended operation.

Tool Cell Inspired Design

Ulti-Form's 135-ton bending machine is designed on the ToolCell platform, LZK's most acclaimed automatic tool change bending machine, and is integrated with industrial robots. The bending machine has a built-in tool warehouse and uses a clamping mechanism in the machine's rear stopper fingers to change tools quickly and efficiently. The bending machine and robot work in tandem to minimize changeover time. The bender completes the tool change when the robot picks up the first part from the input stack and centers it. Ulti-Form can handle parts from 50 x 100 mm to 1200 x 800 mm and weigh up to 25 kg.

No Robotics Instruction

Thanks to LZK's powerful programming wizard, Ulti-Form is an easy-to-use automation with a fast "art-to-part" process. Both bending machine and robot programming are handled offline, with no robot tutorials required. CADMAN®-B software automatically calculates the optimal bending program. The robot software imports all bending data and automatically calculates all fixture positions, taking into account fixture forces, collision detection and robot accessibility. It generates the fastest collision-free path for the robot throughout the bending operation. The system's database contains all the setup information needed for the bending machine and robot so Ulti-Form is quickly ready for production.

Adaptive Gripper

The Ulti-Form robot gripper is an adaptive design designed by LZK (patent pending). It has the flexibility to adapt to multiple part geometries and automatically adjusts to the size of the part. This allows a range of different part geometries to be handled without the need to change grippers, thus keeping production continuous and uninterrupted.

Quality Assurance

Ulti-Form is equipped with LZK's Easy-Form® Laser Adaptive Bending System, which provides automation with quality assurance. Real-time in-line adaptive bending technology adds advanced process stability to robotic bending machine bending. The Easy-Form laser system adapts to material variations, including sheet thickness, strain hardening and grain direction, automatically compensating for any changes to ensure consistently accurate bending results.

Automation Today

Ulti-Form is a modern, automated bending system. Its efficiently organized layout has a footprint of only 8 x 10 meters. The system includes three input pallets, a large output area and small part placement area, an automatic pallet dispenser and transfer system for transferring complete pallets out of the system.

Ulti-Form is designed for flexibility and can be run automatically or in manual mode. Manual operation can be used for very complex parts and small batches; automated production of long series.

Ulti-Form is flexible, efficient and easy to program and operate, providing a fast return on investment.
