How to Use a Multifunctional Angle Ruler to Bend Sheet Metal

A multifunctional angle ruler is necessary when bending sheet metal.

How to correctly use the multifunctional bending meter

(1) Measure the angle between 0° – 50°

The angle ruler and straight ruler are all installed, and the measured part of the product is placed between the measuring surfaces of each ruler of the base ruler for measurement.

(2) Measure the angle between 50° – 140°

The angle ruler can be removed and the ruler can be installed to connect it to the sector plate.

The measured part of the workpiece is placed between the measuring surface of the base ruler and the straight ruler for measurement.

(3) Measure the angle between 140° – 230°

Remove the straighter ruler and clamping block and install the angle ruler only, but push the angle ruler upward until the intersection line of the short side and long side of the angle ruler is aligned with the sharp edge of the base ruler.

Place the measured part of the workpiece between the measuring surface of the base ruler and the short side of the angle ruler for measurement.

(4) Measure the angle between 230° – 320° (i.e. the internal angle of 40° – 130°)

Remove the angle ruler, the straight ruler and the fixing block, leaving only the sector plate and the main ruler (with base ruler).

Place the measured part of the product between the base ruler and the measuring surface of the sector plate for measurement.

This article introduces how to use the angle ruler when measuring angle and how to read the universal angle ruler.

The reading method of the universal angle ruler is the same as that of the caliper.

First read the angle in front of the zero offset line and then read the vernier “minute” angle value.

The sum of the two is the value of the angle of the measured part.

1 when the angle of the workpiece is > 90 º ~ 180 º, the measured angle = 90 º + the reading of the angle measuring ruler.

2 when the angle of the workpiece is > 180 º ~ 270 º, the measured angle = 180 º + the reading of the angle measuring ruler.

3 when the angle of the workpiece is > 270 º ~ 320 º, the measured angle = 270 º + the reading of the angle measuring ruler.
