Press Brake Machine Back-gauge Introduction

Press brake is a specialized equipment used for bending sheet metal .Due to its simple operation and good process versatility,it is widely used in the sheet metal processing industry.The most crucial point in controlling the bending product accuracy lies in the press brake's backgauge.Today,we will discus how to adjust the backgauge of a CNC press brake. 
Adjusting the press brake back-gauge of a press brake depends mainly on the type of CNC system your press brake is equipped with ,as well as whether it has a servo motor 
or a frequency converter.Only these systems can adjust the speed.Generally ,the adjustment of the backgauge is done through the CNC system.such as the DA53T CNC system. 
You can input the required valves into the CNC system,then click to run,and the backgauge will automatically move to the size you set.This is the adjustment of the backgauge from front to back. 

If you need to adjust the backgauge from left to right or up and down.It depends on the type of system your press brake is equipped with ,such as the 3+1 axis electric hydraulic servo press

brake ,where the backgauge's left,right ,up and down must be amnually adjusted.However ,the 4+1 axis electric hydraulic servo press brake does not require manual adjustment ,as the backgauge's up and down can be adjusted through the CNC system,and the backgauge's left and right can be adjusted through the manuipulation rod on the foo pedal switch.

How to adjust a CNC press brake after bending error occurs:

When using a CNC press brake for work ,there is a high possibility of some usage errors.At this time,attention should be paid ,the press brake should be checked once it has a problem.

The first step in checking is to determine of the press brake's mold has any war or damage.If this phenomenon causes an error,you can replace the mold.

In the process of checking the CNC press brake ,if there is no damage ,check the parallelism of the slide and the worktable.If it does not meet the requirements,you can adjust it according to the relevant standard requirements to keep the parallelism within the allowable range.

Movement of the backgauge mechanism of the press brake

The backgauge mechanism of the press brake moves forward and backward using a DC servo motor(or an AC servo motor),whose rotational motion is transmitted to the ball screw via a toothed belt transmission ,and then becomes linear motion through the nut ,driving the drag plate and the backgauge rack along the guide axis.
