Why is the middle of the plate bent by the press brake

The middle of the plate bent by the bending machine is bent with an R angle, which is generally related to the thickness of the plate. If the intermediate curvature marked in the technical requirements is exceeded, the straightness of the folded part cannot meet the requirements. The following methods are available for reference:

1 .It may be caused by the unevenness of the upper and lower knives, and the mold is offset from the included angle, so the angle is the same, and the straightness is not enough.

2 .There is no deflection compensation, and the reason is similar to that of each pair of molds, resulting in displacement.

3 .The method can be used to measure the upper slider and the lower workbench with a height gauge to see if it is parallel, if the mold has been parallel, then find other reasons to find a way to solve it.

If the angle is inconsistent, the oblique block can be adjusted to reduce the error. If there is no problem with the upper and lower molds, the pressure of the press brake is uneven or the upper tool holder is deformed. Put a few thin sheets of paper at the bottom of the lower mold, and slowly adjust it.

In the case of middle bending, the straightness of the folded part cannot meet the requirements.

1 It may be caused by the unevenness of the upper knife and the lower knife, in order to achieve the angle, the quick clamp is moved, so the angle is the same, but the straightness is not enough.

2 The reason is that there is no deflection compensation, and the reason is similar to the first one.

3 Method: You can use the meter method to play the upper slider and the lower workbench to see if it is parallel, find the reason and then find a way to solve it.

Caused by inconsistent angles, adjusting the oblique block can reduce the error.

If there is no problem with the upper and lower molds, it is that the pressure of the cylinder is uneven or the upper tool holder is deformed. Put a few thin sheets of paper at the bottom of the lower mold and slowly adjust it.

Of course there was an R angle, and it was related to the thickness of the board.

Hello, dear. The hydraulic press brake can not go up and down may be due to the following reasons:1Check whether the electric Hu Qi action is normal 2Check if the hydraulic valve is clogged3Check whether the back pressure valve is adjusted or not4Whether the foot pedal is out of order.

When the foot pedal is up, the left and right lights on the hydraulic valve are on at the same time.

When the foot pedal is down, there is no response.

Excuse me, yes, there is a problem.

Leaks in the hydraulic system. Measure the stroke of the brake pedal frequently with appropriate intervals. Pedal travel is the distance the pedal travels towards the floor from a fully released position.

Allow the engine to idle and keep the propeller shaft in the center position. Press the brake pedal and keep the pedal force constant. If the pedal slowly falls under the same force, Fushizakura may have a leak due to the lack of the hydraulic braking system.

Why is the angle of the two sides different for ordinary bending machine.

1. The pressure is not the same, which is caused by the lack of shelter between the adjustment tools and the uneven situation. 2. The hydraulic stroke is different. 3. The middle of the lower mold is worn excessively, or the middle of the upper mold is worn and deformed, resulting in insufficient intermediate forming.

Summary. Hello dear! We'll be happy to answer for you.

Why is the angle of the two sides different when the ordinary bending machine bendsAnswer: because the stroke of the cylinder is different. The bending machine is a kind of machine that can bend a thin plate, and its structure mainly comprises a support, a workbench and a clamping plate, the workbench is placed on the support, the workbench is made up of a base and a pressing plate, the base is connected with the clamping plate by a hinge, the base is composed of a seat shell, a coil and a cover plate, the coil is placed in the depression of the seat shell, and the top of the depression is covered with a cover plate.

When used, the coil is energized by the wire, and the gravitational force is generated on the pressing plate after the power is applied, so as to realize the clamping of the thin plate between the pressing plate and the base. Due to the use of electromagnetic force clamping, the pressure plate can be made into a variety of workpiece requirements, and the workpiece with side walls can be processed, and the operation is also very simple. The press brake is divided into manual press brake, hydraulic press brake and CNC press brake.

The manual bending machine is divided into mechanical manual bending machine and electric manual bending machine, and the hydraulic bending machine can be divided into torsion shaft synchronization, machine-hydraulic synchronization, and electro-hydraulic synchronization according to the synchronization mode. Hydraulic press brakes can be divided into the following according to the mode of movement

Upward and downward movement.

Why is the angle of the two sides different for ordinary bending machine.

Hello dear! We'll be happy to answer for you. Ordinary bending machine, the angle of the two sides is not the same, why is it A:

Because the cylinder stroke is different. The bending machine is a kind of machine that can bend the thin plate with a ridge and a spike, and its structure mainly comprises a support, a workbench and a clamping plate, the workbench is placed on the support, the workbench is made up of a base and a pressing plate, the base is connected with the clamping plate by a hinge, the base is made up of a seat shell, a coil and a cover plate, the coil is placed in the recess of the seat shell, and the top of the depression is covered with a cover plate. When used, the coil is energized by the wire, and the gravitational force is generated on the pressing plate after the power is applied, so as to realize the clamping of the thin plate between the pressing plate and the base.

Due to the use of electromagnetic force clamping, the crushed plate can be made into a variety of workpiece requirements, and the workpiece with side wall can be processed, and the operation is also very simple. The press brake is divided into manual press brake, hydraulic press brake and CNC press brake. The manual bending machine is divided into mechanical manual bending machine and electric manual bending machine, and the hydraulic bending machine can be divided into the following according to the synchronous mode

Torque shaft synchronization, machine-hydraulic synchronization, and electro-hydraulic synchronization. The hydraulic bending machine can be divided into upward and downward movement according to the mode of transportation and movement.

The angle difference between the two ends of the bend is 30 degrees.

How it should be adjusted.

Dear, the asymmetrical adjustment of the two ends of the bending machine in the process of bending Li Jinsong: according to the error of the angle at both ends of the bending plate of the bending machine, the use of the bending machine above the hexagonal tube can be disassembled at one end which Zheng can be adjusted unilaterally, the Y-axis handwheel rotates a circle, and adjusts it to a suitable state according to the size of the angle error, and the hexagonal tube at the released end can be connected to the normal use. Check whether there is any deviation in the free state on both sides of the press brake (both sides of the normal range are allowed, and the deviation value is not within the range, you can use the eccentric sleeve on one side to make appropriate adjustments until the two sides are adjusted to the allowable range, and it can be used normally.)

Because the bending machine has to stretch the plate upwards in the process of use, it is inevitable that it will hit the mold or slider, so it will lead to inaccurate bending.

Hello bending rent, the possible reasons why the bending machine can not go up and down are: 1The problem of the source of electricity trouble:

Check whether the power supply is properly connected and whether the wires are short-circuited or broken. 2.Control System Issues:

It could be that the controller is malfunctioning, or the sensors connected to the controller are failing, causing the machine to not be able to perceive the operator's commands. 3.Mechanical Component Issues:

It may be that the internal parts of the machine are damaged or loose, causing the machine to not function properly. The above are common reasons, but the specific reasons need to be checked and repaired on a case-by-case basis.
