Abstract
Metal material bending test device with improved testing accuracy is provided. The device includes a pedestal mechanism including bent pedestals on both sides, bent support rolls fitted on the bent pedestals via rotating shaft, two parallel drawbars connected between the two bent pedestals. The bent support rolls have diameter of 70-160 mm, and the centers of drawbars is arranged at area about 120 mm around the stress center of the bent support rolls. In addition, multi-pressure heads mechanism and sample automatic take-out device can also be provided. In the utility model, diameters of the bent support rolls are increased, hence the distance between the stress centers of the two bent support rolls is widened to reduce testing load; and the drawbar is as close as possible to the stress centers of the rolls, so that lateral force can be effectively offset to improve test accuracy and efficiency. The device is convenient in operation, and is suitable for cold bending test of metal material.
Description
Technical field
The utility model relates to a kind of metal material bending test equipment.
Background technology
Metal material is most important starting material in the development of the national economy.Along with the continuous expansion of China's Foreign Trade in recent years, metal material outlet becoming the again new growth point of earning foreign exchange.Therefore, the quality control of metal material just becomes the emphasis in each big steel enterprise and the quality testing department work.
Bending strength is one of important technology index that shows the metal material quality good or not.So far, the test result of this performance, most of enterprise and detection unit obtain by testing on the universal testing machine.But for universal testing machine, this test Just One Of Those Things kind subsidiary function, so its efficient, effect are all unsatisfactory.So the cold bend test special plane has been produced demand.But mainly there is following problem in existing cold bending test machine.
In cold bend test,, cylinder lever connecting rod is housed between Bending support in order to offset the lateral compression power that test produces.But existing bending roller diameter is all less than 60mm, and the distance between the two bending roller center of effort is little, and working load is big; And the pull bar installation site is unreasonable, is installed under the revolving shaft center, Bending support bottom below the 120mm, so it is yielding effectively to offset the side force Bending support.Cause test effect undesirable, and test load is bigger.
Existing material test compressing head is a pressure head, changes pressure head operation inconvenience, inefficiency, and labour intensity is big.
In cold bend test, when off-test, owing to the effect of material internal stress or the reason of misoperation.Sample tends to be stuck in and is difficult between two rollers take out.
Summary of the invention
The purpose of this utility model is to be to overcome above-mentioned because of lateral compression power causes the defective of Bending support distortion, and provides a kind of metal material bending test isolated plant.It is easy to operate that isolated plant can also realize changing pressure head, and sample is convenient to remove.
The technical solution of the utility model is, metal material bending test isolated plant, it comprises a seat mechanism, this seat mechanism comprises the Bending support that is arranged on both sides, be arranged on bending roller on the Bending support by revolving shaft, before and after two parallel draw bars be connected between the Bending support of both sides, its feature in, described bending roller diameter is between φ 70mm-φ 160mm; The pull bar center is arranged on bending roller center of effort up and down in the 120mm scope.
The further technical scheme of the utility model is: described pull bar is by the center of effort of revolving shaft.
The further technical scheme of the utility model can also be: described metal material bending test isolated plant, it is characterized in that, also comprise a pressure heads mechanism that cooperates with a seat mechanism, described pressure heads mechanism is fixing single-revolution clamp body on a main shaft, and a plurality of pressure heads are installed on the rotary jig body.When test need curved be changed the pressure head specification, only need to rotate the rotary jig body, can easily finish replacing.Test be can greatly save like this and required time and testing crew muscle power adjusted.
The further technical scheme of the utility model can also be: comprise that also one is arranged on the sample automatic device for taking out on the pressure heads mechanism, this sample automatic device for taking out upper end is fixedly connected on the main shaft, and following end hook is pulled in the bottom of sample.
Described sample automatic device for taking out is frame or loop configuration, and the upper end is fixed on pressure heads mechanism or the entablature, and the bottom is around the bottom of sample.Adopt modes such as pull bar (plate), chain, wire rope, chain link, drag hook to be installed on the sample unloading device that frame or ring texture were located and formed to seaming chuck mechanism, entablature, main shaft etc.
The beneficial effects of the utility model are,
Because it is big that the bending roller diameter becomes, make the distance between the two bending roller center of effort strengthen, the test load that makes reduces, simultaneously the center of effort of the as close as possible bending roller of pull bar, and when consistent, can offset side force effectively with bending roller center of effort.
Owing to, can select the crooked pressure head of specification the most frequently used more than two is installed on it simultaneously at machine seaming chuck partial devices one main shaft and rotary jig body.When test need curved be changed the pressure head specification, only need to rotate the rotary jig body, can easily finish replacing.Test be can greatly save like this and required time and testing crew muscle power adjusted.
Owing to be provided with the sample withdrawing device, after off-test, utilize oil cylinder opposite force or gravity that sample is taken out automatically.
