Top 10 Considerations When Using Press Brake Toolings

Press brake toolings are made of high-quality steel products made by special heat treatment, with high hardness, not easy to wear and tear, able to bear great pressure, but each mold has its limits pressure: ton/meter, so choose the length of the mold when using the press brake toolings correctlyThat is, how much pressure per meter to bear, must not exceed the marked limit pressure.
In order not to damage the die, we stipulate that align with the original point, it is necessary to use the upper and lower modes with the length of 300mm to do the alignment.The upper mold lower mold of the same height only can be used after the alignment.It is strictly forbidden to use the split small mold for the alignment, and the alignment must be based on the regulated pressure inside the press brake machine.
In the use of the mould, due to the various height of the molds, the mold can only be used in a press brake machine with the same height, which can not be used in different heights.
When using the press brake toolings, choose the right upper die and lower die according to the sheet metal hardness, thickness, and length.Generally, the slot width of the lower die should be 5-6 times the thickness of the metal plate, while the length should be longer than the sheet.The harder and the thickness of the sheet metal material, the wider of the lower die slot.
When bending an acute angle or a dead angle, 30° punch should be chosen. Bending the acute angle first, then flattening.When bending R angle, R punch and R die should be chosen.
In bending the long piece of work, it is better not to use a segmented mold in order to reduce the indentation at the mold connection position, and it is better to choose a single slot die, because the exterior angle R of lower die with single slot V is big, not easy to generate bending indentation.
When selecting the top punch, we should know the type of die and the parameters well, and then decide which punch should be used based on the shape of the product that needs to be formed.
When bending hard or too thick product, do not use press brake die to bend steel bar or other cylinder products.
When using the press brake mold, the operators should have a clear mind.The upper die and lower die of press brake machine should be locked after alignment, in case the punch fall down to hurt the workers or damage the die.Attention should be paid when adding pressure during the operation process, do not add too much pressure and pay attention to the data changes on the display screen.
After finish using the press brake toolings, put the die back in the press brake die cabinet (press brake store) according to the marking, clean the dust on the mold regularly, and apply the anti-rust oil to prevent rust which will reduce the precision of the toolings
