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.

What are the common faults of press brake?

Press brake makes poor surface roughness of the workpiece. The tool tip of the press brake is damaged that is not sharp. The press brake resonates leading to the unstable placement. The press brake has a crawling phenomenon, resulting in poor processing technology.

The workpiece produces taper-size head. The level of the press brake is not adjusted properly that one side is high and the other is low, resulting in uneven placement. When turning the long shaft, the material fed is too hard to be cut deeper. The tailstock thimble and the spindles are not concentric.

The size of each workpiece is inconsistent. The carriage of the press brake runs at high speed for a long time, resulting in the wear of the screw and bearing. The repeated positioning accuracy of the tool holder produces deviations during long-term use. The carriage can accurately return to the starting point of processing every time, but the size of the processed workpiece is still changed. It is generally caused by the main shaft, caused by the high-speed rotation to wear.

How to avoid electric leakage when the press brake is working?

For the press brake, it is inevitable that there will be leakage in the working process. If the leakage is not handled in time, it will damage to safety.

In order to avoid the occurrence of electric leakage when the press brake is working, the press brake must be equipped with a leakage protector, it is a current-driven leakage maintenance device, which has a good effect on the protection of the press brake.

When operating the press brake, if the insulation of the electrical installation equipment is damaged, the cover will be charged. The correct grounding and zeroing work must be done. The electrical installation of the press brake should be maintained with high-voltage grounding to reduce the risk of electric shock.

The wiring operation of the press brake is also very simple. It is enough to connect the metal shell and the common maintenance neutral line firmly. Lead out from the neutral line on the power side of the leakage maintainer. Under the protection of its maintainer, the press brake can maintain a good and stable situation.

Why there are errors when using the press brake?

The outer circle of the bend is a cone. The connection between the front and rear centers is not coaxial with the spindle axis, which is caused by the wrong position of the tailstock center of the press brake.

The workpiece vibrates when bending. It may be that the tailstock sleeve of the press brake extends too long or the support of the workpiece is too loose. The mold is not sharp enough or the arc is too large. The bearing clearance of the rotary center is large. The clearance of the medium and small sliding plates is too large.

The mold does not meet the requirements. The mold and the main shaft axis of press brake are not on the same axis. The circular runout caused by the wear of the bearing. The center hole of the workpiece is not cleaned or is fuzzed. The center hole does not work because the lever in the center of the mold touches the end face of the chuck.
