Description
Technical field
The invention belongs to shape bending technical field, be specifically related to the test device of a kind of bending machine upper sectional material bending force.
Background technology
Along with section bar day by day increases in the application of the aspects such as building, electronics, automobile and track traffic, the shape of section bar also day
Become variation, often shape bending is deformed in real work.Section bar is all directly to be curved on bending machine at present,
Even if the section bar of same specification, due to manufacturer, batch, the difference of material composition, during bending, required bending force and material
Resilience the most different, here it is the shaping amount after causing section bar to bend on bending machine is relatively big, add labor during shaping simultaneously
Fatigue resistance, production efficiency is low, and product quality can not be guaranteed.
Summary of the invention
It is an object of the invention to provide the test device of a kind of bending machine upper sectional material bending force.The present invention is by bending
Increase a set of stress test device on machine, substantially reduce the shaping amount after shape bending, reduce labor intensity, improve life
Produce efficiency.
The technical solution used in the present invention: the test device of a kind of bending machine upper sectional material bending force, it includes that test supports

Placing the draw-in groove composition of described section bar, wherein draw-in groove is a U-shaped structure, and described draw-in groove is separately fixed at the two ends of connecting plate, and
Being positioned on the same plane of connecting plate, servo electric jar is fixed on connecting plate, and servo electric jar is positioned at same with described draw-in groove
In one plane, test bracing frame is fixed on described bending machine by connecting plate, and pressure transducer is fixed on servo electric jar
On the axle head of projecting shaft, the stress test head of pressure transducer is for testing the STRESS VARIATION of section bar, the output of pressure transducer
End is connected with the controller communication of bending machine.
Further, described card trench bottom is provided with a cushion block, and the section bar tested props up and is located on cushion block.
Further, described servo electric jar is positioned at the middle part between two draw-in grooves on test bracing frame.
Further, the opening upwards of described draw-in groove, and the axle head of the projecting shaft of servo electric jar is positioned at the groove depth of draw-in groove
Medium position.
Further, the model of described strain gauge is CFBLY.
Further, described draw-in groove is provided with reinforcement connecting plate with the junction of connecting plate.
Compared with prior art it provides the benefit that the present invention: the stress test device of the present invention is arranged on shape bending
Before, owing to the test of stress realizes by sensor, it is ensured that the accuracy of test data, the bending of section bar simultaneously is to pass through
CNC controller realizes, so the shaping amount after shape bending reduces；The digital control system utilizing this device bending machine can basis
The difference of section bar stress value adjusts technological parameter during bend pipe automatically；Present invention decreases labor intensity during shape bending, greatly
Improve greatly production efficiency, ensure that product quality and aesthetics simultaneously.
