Iron plate CNC Hydraulic Press brake bending machine cylinder and operation matters
Oil cylinder is used to load hydraulic oil, and numerical control bending machine is a kind of machine used to bend metal sheet.
When we use CNC bending machine to bend materials, we must bend in the middle section. If we bend at one side, then when one cylinder
touches the workpiece, the other cylinder continues to go down. Until the other cylinder touches the lower die, the two cylinders begin to pressurize.
The cylinder works high at one side and low at the other, and soon CNC bending machine cylinder. It will damage and leak oil.
Secondly, try not to choose two cylinders of CNC bending machine, because such CNC bending machine working life is too short.
When the workpiece is in the middle of the CNC bending machine and the cylinder is on both sides, the bending of the slider is affirmative.
In addition, the reaction force produced by the inclination of the slider causes the middle of the slider to protrude outwards, which leads to
inaccurate bending of the CNC bending machine.
Since two cylinders of CNC bending machine can not be selected, then three cylinders of CNC bending machine, the third cylinder in the middle,
the force point is directly in place, the slider does not deform, will not protrude, fully ensure the accuracy of CNC bending machine, but also can extend the service life of equipment.
In addition to the proper selection of CNC bending machine itself, some important parts of CNC bending machine have to be adjusted reasonably,
such as the press foot of CNC bending machine, which is used to press steel plate when bending. If the seal of CNC bending machine leaks,
the pressure of press foot will be insufficient, and the phenomenon of steel plate skidding will occur, resulting in the damage of scissors and clippers.
In this regard, we must pay attention to check the press foot of CNC bending machine to prevent leakage of its seals. If the problem has occurred,
we should replace the seals in time to ensure that the press foot of CNC bending machine has enough pressure to press the steel plate, so as to provide
a good basis for the smooth completion of the bending work.
The above is why you want to buy CNC bending machine to see the specific content of the cylinder, I hope to help you. More information about
CNC bending machine can be seen in the earlier stage of our company. If you have any questions, you can contact our staff. We will answer them for you one by one.
Iron plate CNC Hydraulic Press brake bending machine cylinder and operation matters
Hydraulic bending machine includes bracket, worktable and clamping plate. The worktable is placed on the bracket. The worktable is composed of a base and a pressure plate.
The base is connected with the clamping plate by hinges. 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 connected by the wire .
In the bending process of the bending machine, there is no pressure between the upper die and the lower die. The required bending angle is obtained
by adjusting the depth of the die opening. This bending method is called bending clearance. Deep into the lower die die, the bending angle of
the bender is small, the larger, and vice versa. Because of elastic materials, the advantage of bending clearance is that when bending
controls springback and over bending, you can use fewer moulds
to achieve a variety of angles, processing and less pressure. Normally, in order to obtain the best bending effect, the ratio of material thickness T to
V-shaped opening width of V-shaped lower die is based on T:1:8V:
The following points should be paid attention to in the operation of hydraulic bender:
- In this process, the pressure weakness automatically stops falling, while the pressure or the process of a large increase slows down, and can not fall or rise.
- Automatic stop when pressure; increase is normal, not rapid decline, but the normal pressure of the product.
- When high and low pressure products. Sometimes it’s half normal, sometimes it’s half abnormal. But when the relationship is normal, the two sides are abnormal.
- The normal and abnormal middle of the two sides.
