Hydraulic Press Brake For Sale

We have been producing press brakes for more than 20 years and have rich experience. At the same time, we have established deep relationships with various global technology and parts partners to ensure the stable operation of the press brakes we sell.

Press Brake

NC Press Brake

If you have limit budget, the NC press brake will be a good choice for you to finish sheet metal bending.

Press Brake

CNC Press Brake

CNC press brake has much higher accuracy, efficiency than NC press brake when bending metal plate.

Robotic Press Brake

Robotic Press Brake

Robotic press brake It can efficiently and accurately complete the automatic bending of sheet metal.

How to set the K factor, bending deduction, bending allowance and bending calculation in SolidWorks? What’s their relationship?

The bending allowance table is a table you make in advance and insert it when drawing sheet metal parts in the future. It will be added automatically according to the plate thickness.

K factor is mostly used for non 90 ° bending or large arc bending (it can be set according to the deduction of plate bending by your bending machine).

Bending deduction is to subtract a dimension from each bend (according to the plate thickness and lower die width, such as 2mm cold plate and 16mm lower die, the bending deduction is about 3.4mm; For example, if a 2mm sheet metal part has 20mm sides and 80mm sides, the unfolding length is 20 + 80-3.4 = 76.6mm). It can be set in the sheet metal option of the part you draw, or it can be set in the bending.

The K factor is usually not used.

However, for non 90 degree and large arc bending, the bending deduction is obviously not accurate, so the K factor must be determined;

The method is:

Draw a right angle sheet metal part, set a correct bending deduction, then click unfold, measure and record the unfolded size.

Go back and set a K factor, such as 0.25, and then click expand to see if the expansion size is the same as that just now.

If it is the same, the K factor is right. If it is different, go back and adjust the K factor until the unfolded size is the same as that deducted from the previous bend, then the K factor is right.

Write it down.

For plates of the same thickness, you can use this K factor to calculate.
