Description
Technical field
The present invention relates to bar bending testing equipment fields, more particularly, to a kind of reinforcing steel bar bending tester.
Background technique
The reinforcing bar produced need to measure material bear bending load when mechanical characteristic test, this is material mechanical
One of the basic skills that can be tested, provides reliable material for machine-building, civil engineering, metallurgy and various other industrial departments
Mechanical property parameters guarantee the trouble free service of machine (structure) and its part (component) convenient for reasonably using material.Reinforcing bar
Test sample card applies stability force among support arm and flexual center, by pressure head clockwise, so that sample is generated deformation, observes it after 180 ° of bending
It is whether intact after clod wash, mechanical property is detected, whether the outer surface and side for detecting knee have an impact surface quality of steel
Defect.
It is that 2012 concrete reinforcement steel material test method of the standard GB/T of people's republic magnificent/T28900-is issued
After cloth, reinforcing bar needs to test the performance of reinforcing bar before factory or before use, in order to guarantee subsequent use reliability,
Especially carrying out alternating bending test to reinforcing bar using angle-bender is one of important test step, and when test can detect reinforcing bar
Bending performance repeatedly, the data such as anti-fatigue performance.When carrying out bending repeatedly to reinforcing bar, bending, bending first are carried out to reinforcing bar
After the completion, then manually reinforcing bar is placed in turn, inverse bending is carried out to reinforcing bar.
Need manually to be repeated the orientation for manually adjusting style reinforcing bar between pinch roller and pressure head during this, because
Speed is slow when this test, inefficiency.
Summary of the invention
The object of the present invention is to provide a kind of reinforcing steel bar bending testers, be provided at the top of rack positive bending mechanism and
Inverse bending mechanism, and it is provided with positive staking punch and reversed staking punch, positive bending can be carried out to reinforcing bar, then followed by
