Bending Machine working principle and Adjustment

Macchina piegatrice Working Principle is essential knowledge for anyone in metal fabrication. As a professional in this field, I frequently work with bending machines and have gained an in-depth understanding of their operation. In this article, I will explain how these machines function, enabling precise and accurate bends in various materials. Using hydraulic or mechanical systems, bending machines apply force to shape metal sheets into desired angles and forms. I will break down the key components and processes, demonstrating how this technology enhances efficiency and quality in manufacturing. Join me as we explore the mechanics behind bending machines and their critical role in the industry.

⒈Bending machines– Turn the handwheel to fine tune the distance of the slider at the bottom dead center to take the positive workpiece angle value; push the handle in, the left coupling is disengaged, and turn the handwheel to adjust the slider between the bottom dead center and the work surface. The piegatura angle is poor.

⒉– The slider upper limit stops the head and the slider stroke can be adjusted to increase productivity.

⒊– The working stroke starts, and when the contact switch is touched, the working stroke speed starts, and the working stroke speed ar adjusted by the potentiometer.

⒋– Pressure adjustment, if the workpiece angle is small and large at both ends, the pressure can be increased appropriately. Otherwise, the pressure should be reduced.

⒌– The electric button board is followed by a power indicator light, a key switch, a motor start switch, an emergency stop button, a pointing device, and a changeover switch. The potentiometer is used to control the length of the working stroke time, and can also control the holding time of the work. The changeover switch can select the jog, single and continuous action of the slider.

⒍– The upper mold is fixed and fixed by a wedge structure to ensure the straightness of the cutting edge and the uniformity of the gap between the upper and lower molds.

⒎–The electric box mechanical interlocking device can automatically cut off the power when opening the electric box door to ensure personal safety during maintenance.

⒏– The back gauge is used for positioning the plate in the longitudinal direction and is adjusted by the motor.

⒐– For the lower die, according to the thickness of the bent sheet, select the appropriate die, and the opening size should generally be greater than 8 times the thickness of the material.

⒑– Slider and back gauge push button switch, and small handwheel for fine adjustment of the back gauge.

⒒– The foot switch operates the slider up and down to make jog, single and continuous movements.

Hydraulic System Operation and Safety Guidelines for Bending Machines

The clockwise rotation of the motor drives the axial piston pump to pass the filtered oil through the pipeline into the valve plate and the solenoid valve to return to the mailbox.

The No. 13 hydraulic control check valve closes the lower chamber of the No. 15 cylinder to make the slider stay at any position. At this time, the solenoid valves do not work, and the oil output from the oil pump returns to the mailbox.

When the No. 11 D4 electromagnet works, the slider descends rapidly, and the oil in the lower chamber of the No. 15 cylinder is returned to the mailbox through the No. 17 and No. 15 throttle valves, and the upper chamber of the cylinder is filled with oil.

When the slider hits the limit switch, the No. 5 D2 and No. 12 D3, No. 14 D5 solenoid valves work.

The No. 16 flush valve and the No. 17 cone valve are closed, and the oil output from the oil pump enters the cylinder, and the slider enters the working speed.

The No. 6 high-pressure relief valve is to ensure the rated pressure of the machine, and the 18th remote pressure regulating valve is adjusted to obtain the allowable pressure.

The working time of the No. 5 D2, No. 11 D3 and No. 14 D5 electromagnets is controlled by the foot switch, and the jog distance when the slider is lowered is realized, and the speed at which the slider speed is lowered is adjusted by the No. 9 throttle valve.

After stopping the slider lowering action, move the foot to step on the foot switch.

At the moment of the return trip, the No. 14 D5 electromagnet was first to reset for 2 seconds and then relieved.

Then D1, No. 5 D2/14 D5 electromagnet works on the 10th, and the slider returns. The return speed is constant.

The working pressure of the return stroke is 120kg/cm2, which is adjusted by the No. 10 relief valve.

⒈– Each valve works normally, the power cord is connected reliably, the pipe joint is tightly connected, and there is no oil leakage.

⒉– The pipe is well connected and the anti-vibration pipe joint has no oil leakage.

⒋– The hose connection is free from damage and oil leakage.

⒌– The cylinder is well sealed and there is no oil leakage.

⒍– The pressure gauge is good and has an inspection label.

⒎– The motor is clean and ventilated.

⒏– The oil filter is clean.

⒐– The oil tank oil is clean, the oil mark is clear, the oil level is normal, and the oil temperature is 15~60 °C.
