Hydraulic Press Brake

Factory Direct Sale Without Middleman

We have been manufacturing press brakes for nearly 20 years, and we are able to customize them according to the actual needs of our customers, regardless of their needs.

In order to ensure the quality, service life and processing accuracy of the press brakes, the main components of the machine are all international famous brands, such as Schneider, Rexroth, Siemens, etc.

At the same time, our press brakes are tempered and shot blasted, which most of our counterparts cannot do, and this is one of our advantages.

Press Brake Ram Depth Calculator (Bend Depth)

How to calculate depth of bend on press brake?

The bend depth of the press brake ram is calculated and controlled when the sheet is bent at a certain angle by free bending on the press brake machine.

This is to control the positioning value of the ram when moving up and down.Press Brake Ram Depth Calculator

The upper die mounted on the ram will bend the sheet to a certain position exactly at the sum of the certain set angle and the rebound angle.

In this way, the workpiece can spring back to the set angle after the ram returns.

However, in actual bending, there are many factors that affect the bending angle of the sheet material.

The measured angle of the first bending often does not match the set angle and needs to be corrected.

At this time, the angular error should be converted into the depth correction value to make it corrected.

Calculated by using the formula for the bend depth of the ram for free bending and the formula for correcting the depth of the ram in case of angular error, we have simplified it into a practical formula that can be applied practically at the production site.

We have made it into an online calculator for your convenience and hope it will help you.

  1. I am looking for the formula to calculate the theoratic depth of the ram to get a certain angle.
    But I have a hard time finding this.

    Can you help me with this?

    1. you can use trigonometric tan(theeta) equation for find the depth of ram.

      tan(x)= opp/adj

      you have angle x, how much want to band
      you have opp side as the v opening
      so, you can find depth….adj…
      adj=tan(x)(require bend angle) *opp(v-opening)

  2. I ask for the formula too, i have a old press brake and i need to retrofit. Please give the formula for all is interested. Thank you.

    1. Sorry we can’t provide you the formula, you can use this online calculator anytime if it is useful for you.
