Abstract
The utility model discloses a metal bending tester, which comprises a stander, wherein a limiting device, a swinging device and a tensile fixing device are arranged on the stander, the limiting device is provided with a pair of limiting frames, a limiting block is fixed on each limiting frame and a test-piece positioning groove is formed between the two limiting blocks; the swinging device comprises a swinging rod, wherein one end of the swinging rod is rotatably fixed on the stander, and a test-piece clamp is also fixed on the swinging rod; and the tensile fixing device comprises a weight bracket, wherein a weight is arranged on the weight bracket, and the top of the weight bracket is provided with a test-piece fixing member. Therefore, the tensile force provided by a spring is replaced by gravity, the situation that the provided tensile force is instable is easily caused because an elasticity coefficient of the spring changes in the long-term using process of the traditional metal bending tester, and therefore an accurate testing result is ensured.

Technical field
The utility model relates to a kind of test unit, and a kind of bend test of metal device of more specifically saying so belongs to test machines manufacturing technology field.
Background technology
Bending resistance is one of important indicator of some metal materials, and bending resistance is under certain pulling force, and the number of bends of test button defines, and number of bends is many more, and bending resistance is good more.The bending test of metal is generally carried out on Apparatus for Bending at low-temp.
Existing testing machine for bending test of metal comprises frame, the stop means on frame, pulling force stationary installation and pendulous device, and stop means is used for fixing the inflection point of metal specimen, and stop means generally adopts the flute profile of two spacing formation; The pulling force stationary installation is an end of fixing metal test specimen on the one hand, and the metal specimen pulling force is provided on the other hand; The other end of pendulous device fixing metal test specimen, and through the swing metal specimen is bent.Owing to provide pulling force generally to adopt spring in the pulling force stationary installation of existing testing machine for bending test of metal, unstable because of the change pulling force that causes easily providing of the elasticity coefficient of spring in long-term use on the one hand, thus influence test findings; On the other hand, for the test specimen of different size, need different pulling force, the testing machine for bending test of metal of said structure is changed spring and is seemed inconvenient, therefore, also exists and uses inconvenient deficiency.
The utility model content
To the problems referred to above, it is stable that the problem that the utility model quasi-solution is determined provides a kind of pulling force that provides, and can also be directed against different test specimens, and the convenient testing machine for bending test of metal of regulating pulling force is with warranty test result's the accurate and convenience of using operation.
For achieving the above object; The utility model adopts following technical scheme: a kind of testing machine for bending test of metal; It comprises frame, the stop means on said frame, pendulous device and pulling force stationary installation, and said stop means has a pair of position-limited rack; Fixing limited block on said each position-limited rack forms the test specimen locating slot between said two limited blocks; Said pendulous device comprises fork, and an end of said fork is rotatable to be fixed on the frame, on the said fork also fixedly test specimen press from both sides; Said pulling force stationary installation comprises the counterweight support, is equipped with counterweight on the said counterweight support, and the top of said counterweight support is provided with the test specimen fixture.
The improvement of the testing machine for bending test of metal of the utility model, it also comprises counterweight bracket tray and pallet jacking gear, said counterweight bracket tray is in transmission connection below the counterweight support and with the pallet jacking gear.
At least one position-limited rack and frame are movable fixed.Said position-limited rack and frame for the movable fixed structure are: fixing nest bar on the said frame, and said position-limited rack is provided with adjuster bar, and said nest bar matches with adjuster bar.
Adopt such scheme, the testing machine for bending test of metal of the utility model because said pulling force stationary installation comprises the counterweight support, is equipped with counterweight on the said counterweight support, and the top of said counterweight support is provided with the test specimen fixture.Like this, substituted spring with gravity pulling force be provided, on the one hand, avoided in the long-term use of existing testing machine for bending test of metal elasticity coefficient because of spring to change causing easily the pulling force that provides unstable, thus the warranty test result accurately; On the other hand, for the test specimen of different size, when needing different pulling force, as long as therefore increase and decrease or replacing counterweight have use, convenience operation.
In improvement project; Below the counterweight support, be provided with liftable counterweight bracket tray, during use, can be placed in increase and decrease or replacing counterweight under the state on the counterweight bracket tray at the counterweight support; Move the counterweight bracket tray then; With an end of counterweight support and test specimen fixing after, put down the counterweight bracket tray, make increase and decrease or change convenience, the safety that counterweight becomes.
