A self-calculation method for die size deviation of bending machine

Abstract

The invention discloses a method for self-calculating the size deviation of a bending machine mold. The method includes the following steps: 1) install and press the plate, and set the initial clamping point; 2) bend the plate by 90 degrees, and record the corresponding actual Y target value at this time; 3) bend the plate by 135 degrees, and record this 4) Click the VR navigation function key, and input the actual Y target value when the plate is bent at 90 degrees and 135 degrees respectively; 5) Set the input error convergence interval; 6) Click the automatic calculation function key, Obtain the error convergence result; 7) Convergence is successful, and the recommended notch width, the R angle of the advancing notch and the recommended clamping point compensation amount are obtained. The self-calculation method of the die size deviation of the bending machine in the present invention can automatically calculate the appropriate relevant parameters and the position of the clamping point when the lower die is replaced, which greatly saves the operator's debugging time and ensures that the bending machine at any angle within the range High bending precision, suitable for diverse process requirements.

Problems solved by technology

[0003] For bending machines currently on the market, when bending sheet metal, the notch width parameter V and the chamfer angle parameter R of the lower die will generally affect the bending effect, and considering the error factors of the actual die itself, the given VR is only a reference value

However, sheet metal bending generally requires high precision, and often 2 to 7 wires will cause an error of 1 to 3 degrees, resulting in too large a bending angle error, and it is difficult to fix the error range when bending at any angle , the operator needs to make a sample before bending to find a suitable angle compensation value, which is very time-consuming

In addition, considering that different products often require different bending process requirements, after replacing the new mold, the above steps need to be repeated, which is cumbersome and reduces the processing efficiency
