What are the advantages of CNC press brake?

The main cylinders on both sides of the CNC press brake synchronously adopt a hydraulic control system and a grating ruler to form a closed-loop control, which is independently restricted by CNC. Accurate feedback data ensures safe operation of the slider.

The CNC press brake has high strength and good rigidity. It is stable and reliable with high precision. Backgauge distance and slider stroke adopt electric and manual fine adjustment. CNC press brake is equipped with a digital display device, which is convenient and quick to use.

The CNC press brake has a multi-step programming function, which can realize automatic operation, continuous positioning, and automatic and precise adjustment. The processing of CNC press brake shows real-time display and can remember the position and parameters after power failure.

The backgauge adopts imported ball screw and linear guide to ensure the positioning accuracy.

The CNC press brake uses a servo motor as an actuator. When the bending operation is not performed, the motor does not move and consume power. Therefore, CNC press brake is a product that meets the energy saving requirements. The servo motor has a higher degree of controllability so that it can be well adapted to the production needs of the modern industry.

 

What is the proper CNC press brake setup procedures?

The efficiency and the profitability of a CNC press brake are measured by the number of completed and correct parts produced in a given period of time.

Operators need to know CNC press brake completely. They also should know material type, thickness, flange dimensions and tolerances, angles and angle tolerances, and inside radius of angles.

The choice of tool is based on the drawing. Air bending, bottom bending, and coining are available. Select the tool that is at least as accurate as the specified type.

Tonnage charts are available for air bending. For bottom bending, a good tonnage may be four times than that of the air bending. Coining requires eight times the air bend tonnage.

If you have two or more CNC press brakes, make sure to choose the best-suited one. Remember that air bending cannot overload a CNC press brake.

Determine tooling position on the bench. If the tonnage requirement exceeds the concentrated load limit in the center of the CNC press brake, it can be off-center.

Install the tooling and align the upper and lower.

CNC press brake should be programmed properly, which is very quick.

Bend materials only after completing a good test bend. If something wrong, correct the program until a good part has been formed.

It’s time to run CNC press brake.

 

What are the uses of CNC press brake?

Medical fields are assisted by CNC press brakes in the manufacturing and production of high-tech and crucial equipment, such as X-ray machines, components to emergency vehicles, and the actual construction of hospitals.

Military and defense industries employ CNC press brakes to design and craft components to weapons, vehicles, and other significant equipment. The military industry is one of the most invested by the advanced machines. The usage of CNC press brake speeds up the processes of building and testing new equipment.

The usage and importance of CNC press brakes cannot be understated. Without these machines, precise crafting would not be as widely possible and instituted as it is today. The CNC machine industry has always been at the forefront of innovative design to expand further outside industries.

LZK launches Taurus, a new large-format gantry-style fiber laser cutting machine engineered for extra-large sheet metal cutting capacity. A unique modular design, the machine size begins at a 12-meter bed length and can be expanded in increments of 4 meters to a maximum bed length of 42 meters to suit user needs. The large format allows a diverse range of parts to be cut and efficiently nested, increasing productivity and optimizing material usage.

Large-scale advantages

Taurus offers the flexibility to handle very large sheets or multiple sheets, with a cutting range that ensures high machine dynamics for jobs of different batch sizes, shapes and material types, accommodating workpieces up to 3.3 meters wide and 30 mm thick.

Large parts can be processed without repositioning, while multiple smaller parts can be placed on the cutting table and processed in a continuous manner without interruption. Parts can be cut in one part of the table and loaded/unloaded in another, keeping downtime to a minimum.

Taurus is designed for easy access. Only the gantry comes with a housing, not the entire machine. The mechanical design and drive system ensure high machine dynamics during large format cutting.

The operator has easy access to the controls at all times using two touch panels.

The handheld control unit allows the operator to safely move all axes in manual mode for machine setup or loading the nozzle changer. A camera located in the cutting area and a monitor on the operator console allow continuous monitoring of the cutting process. The cutting area has a removable front panel for easy maintenance.

The machine does not require a special foundation.

For simple cutoff of metal parts, the shearing machine is a very tempting option, which is fast, easy and cheap. The shearing machine involves a moving blade applying pressure and pushes a workpiece up against a fixed blade.

What are the specifications you should know about the shearing machine?

When purchasing metal shearing machine, take the required dimensions fitted various workpieces into account.

Sheet thickness is the sheet or web thickness that can be sheared. Sheet length is the largest dimension of working distance from right to left that can be cut. Sheet depth is the distance from the centerline of the ram to the back frame in a gap frame.

Operating a shearing machine requires strict adherence to safety procedures. Operators can activate the shearing machine using several methods. Operators can control manually by a footswitch, pendant, or push-button. The automatic shearing machine automatically performs without intervention. The shearing machine changes tools and parameters in a pre-programmed manner, such as speed or applied load.

Shearing machines require periodic maintenance. The blade performs sharpening on a regular basis so that shears do not yield poor quality cuts. The angle of the cutting edge and the finish of the grind play important roles in affecting performance and lifespan.

How many parts does shearing machine contain?

The shearing machine is composed of a frame, a pressing mechanism, a blade gap adjustment device, a knife holder, and a hydraulic system.

The rack adopts a combined welding structure with good rigidity, including left and right columns, front wall panels, workbenches, and fuel tanks.

The pressing mechanism is composed of a set of material pressing feet installed at the bottom of the frame beam. After the pressurized oil gets into, the presser foot plunger presses down the steel plate. The presser foot does not reset depending on the spring force until the shearing machine stops.

The adjustment of the upper and lower cutting tool gap is realized by rotating the blade gap adjustment device handle to drive the two pinion gears on the shaft. Rotate the sleeve on the supporting shaft.

The knife holder of the shearing machine is an enclosed-welded structure, having high torsion resistance and good rigidity. It is connected to the frame by two ends of the support shaft, equipped with a shearing and return cylinder.

How to install shearing machine?

The shearing machine must be installed on a solid concrete foundation and fastened with anchor bolts. Install it by a secondary irrigation installation method. Place a level it on the work table for vertical and horizontal correction.

The left and back sides are higher than the right and front sides within the allowable range. All parts of the shearing machine must be inspected comprehensively. Add lubricating oil according to the lubrication diagram. Adjust the tightness of the V-belt and the spring tightness of the pressure plate. Adjust the tightness of the brake belt.

When adjusting the gap of the cutting edge, rotate the flywheel to bring the upper knife holder to the bottom dead center. Loosen the screw fixed the blade. Determine the gap value according to the thickness of the plate. Tighten gradually the bolts and nuts to adjust to the required gap. Finally, tighten all the bolts of the fixed blade of the worktable.

How to perform CNC press brake?

Close the rear protective door of the CNC press brake. Turn on the power. Turn on the switch on the control panel of CNC press brake. Then, start the oil pump. The CNC press brake does not operate at this time. Release all emergency stop switches.

Adjust stroke. Pay attention to adjusting the stroke when using it. You must test it before bending. There must be a gap of plate thickness when its upper die descends to the bottom. Otherwise, it will cause damage to the CNC press brake. The adjustment of the stroke also has electric quick adjustment.

For the selection of bending notches for CNC press brake, a notch with a width of 8 times the thickness of the plate should generally be selected.

Backgauge adjustment generally has electric quick adjustment and manual fine adjustment, which is the same as the shearing machine.

Press down the blue "reset" button on the pedal and the "reset rearguard" button on the electric box, ensuring that the two blue reset indicator lights are off.

Turn the function forwarding switch to the "auto" position and press the motor start button after the controller self-test is over.

The CNC press brake finds the reference point and loads the corresponding bending program. Ensure that the mold installed in the CNC press brake is consistent with the programmed mold. Ensure that the sheet material is consistent with the programming page.

How to adjust the gap between blades of CNC press brake?

Remove the lower blade of CNC press brake and clean it piece by piece. Select one side to install tightly. Check the straightness of the blade in the horizontal and vertical directions.

Remove the upper blade of CNC press brake and clean it piece by piece. Then, the operation is same with that of the lower blade.

The upper blade is fixed. We adjust the blade gap by adjusting the lower blade.

The left and right screws of the lower blade increase the clearance. Loosen the four bolts on the table of the lower blade.

Manually turn the upper blade down to the proper position. The operator adjusts at the blanking area of the CNC press brake.

Use a feeler gauge to roughly adjust to 0.5mm from the unoccupied part of the upper and lower blades.

Manually turn the blade to the middle position and adjust it to 0.5mm.

Manually turn the blade up to the right position where the upper and lower blades are not disengaged. The middle position is roughly adjusted to 0.5mm.

Manually turn the upper blade to the proper position and start fine adjustment.

What should be considered when using CNC press brake?

Before working, you must check the surrounding area of CNC press brake for any objects that may cause harm to it. Make sure the surroundings are clean, especially backgauge. Check the position of the oil mark in the oil tank. Check the hydraulic part for leaks.

The CNC press brake should be operated by professors. The operators must wear the corresponding labor protection supplies.

After turning on the power switch of the CNC press brake, do not start the oil pump immediately. Start the oil pump only after the computer screen displays normal.

After starting the CNC press brake, run it for 2 to 3 minutes without anything. Run the slide block at full stroke for 2 to 3 times. Check the motor and CNC press brake for noise. If the temperature is low, the oil tank and oil circuit must be preheated.
