The utility model has reasonable structure and exact bending test; the test can be completed by one step; the utility model is suitable for the tests of bending deflection performance of various metal materials.

Description

A kind of testing machine for bending test of metal
The utility model relates to a kind of testing machine for bending test of metal, is particularly useful for the check that metal material bears the flexural deformation performance of regulation angle of bend.
The metal current bending test adopts pressing machine usually, universal testing machine etc., as universal testing machine, this device mainly is made up of two backing rolls with enough hardness that are fixed in table top and oil cylinder and the flexual center that is installed under the oil cylinder, because automaton, the distance in the bending test process between its backing roll that this device is not applicable to bending test are operated control by mode manually, it is complicated to pretend industry, poor practicability, efficient is low, and can't once finish test, often cause test failure because of the angle of bend that surpasses regulation.
The purpose of this utility model provides a kind of, can regulate the distance between backing roll automatically, once finishes the automatic control testing machine for bending test of metal of bending test.
The utility model is to realize like this, it comprises microcomputer automatic control device (7), master cylinder (6) and two backing rolls (4) that are installed on the testing machine platform (1) are formed, it is characterized in that installing respectively two gear trains (2) that have displacement transducer in the both sides of two backing rolls (4), two backing rolls (4) are connected by the end of connecting rod (3) with two gear trains (2) that have displacement transducer, and the other end that two gear trains (2) of displacement transducer are housed links to each other with automaton (7).
The utility model has the advantages that can not only control master cylinder (6) by the microcomputer automatic control device makes flexual center (5) reach the stroke of setting, can also adjust the spacing of backing roll (4) automatically, make test reach the angle of bend of setting, can once finish bend test of metal.
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing 1 is a structural representation of the present utility model.
Main points of the present utility model are technical parameters of setting to automaton (7) input, be installed in two gear trains (2) that have sensor by connecting rod (3) connection of backing roll (4) both sides by microcomputer automatic control, adjust two spacings of accepting the backing roll (4) of sample, make it to reach the distance of setting.
Another characteristics of the present utility model are that the gear train (2) that has sensor can adopt hydraulic jack, this oil cylinder one end is connected with backing roll (4) with connecting rod (3), the other end is connected with microcomputer automatic control device (7), install displacement additional and pass the master cylinder (6) of device under control of microcomputer, be used for adjusting the stroke that is installed in the following flexual center (5) of master cylinder (6), the microcomputer automatic control device also is used for adjusting two spacings of accepting the backing roll (4) of sample simultaneously, make it to reach setting apart from S, with reference to Fig. 1.During test sample (8) is placed on two backing rolls (4), start master cylinder (6), make flexual center (5) reach the stroke L of setting, thereby can make sample bend to the angle of regulation or occur till crackle, crack, the brisement.And then start master cylinder (6) and two auxiliary oil cylinders (2), and make flexual center (5) and two backing rolls be returned to initial position, this moment, whole bending test was finished.
Another main points of the present utility model are that the described displacement gear train (2) that has can also adopt screw mandrel to replace, and the effect of its transmission effect and oil cylinder is identical.
The utility model is simple in structure, and bending test is accurate, can once finish test, saves sample, is applicable to the check of various metal material flexural deformation performances.

Claims (3)

1, a kind of testing machine for bending test of metal, comprise microcomputer automatic control device (7), master cylinder (6) and two backing rolls (4) that are installed on the testing machine platform (1) are formed, it is characterized in that installing respectively two gear trains (2) that have displacement transducer in the both sides of two backing rolls (4), two backing rolls (4) are connected by the end of connecting rod (3) with two gear trains (2) that have displacement transducer, and the other end that two gear trains (2) of displacement transducer are housed links to each other with automaton (7).
2, testing machine for bending test of metal according to claim 1 is characterized in that the described gear train (2) that has displacement transducer adopts hydraulic jack.
