BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a material testing device for a material test strip continuous body in which a plurality of test strips are continuously and integrally formed.

[0002]

2. Description of the Related Art A conventional material test piece is composed of a small piece having gripping portions 1 and 1 at both ends and a narrowed portion 2 at an intermediate portion as shown in FIG. It was configured to hold the gripping parts 1, 1 of the material test piece made of a single body and perform a tensile test.

[0003]

Since the conventionally known material testing apparatus is designed to grip a test piece consisting of a small piece as described above, a test piece consisting of a small piece is automatically held in the gripping part of the testing apparatus. However, there is a problem that the supply mechanism for supplying the test piece to the device is complicated, and it is difficult to safely and surely supply the test piece composed of a small piece and surely grip the test piece.

The inventor has developed and proposed at the same time a material test piece continuum 10 shown in FIG. 3 for the purpose of solving the problems of the test piece consisting of the small piece. In this material test piece continuous body 10, a plurality of punched holes 15 are formed so that a plurality of single-shaped test pieces are arranged side by side, and the four-sided frame portion 1
4 has a square shape such as a sheet shape, a film shape, or a plate shape integrally formed. Each of the plurality of test pieces formed between the plurality of holes 15 has the gripping portions 11, 11 and the narrowed portion 12 therebetween.

An object of the present invention is to provide a novel material testing apparatus for carrying out a material test by using this material test piece continuum.

[0006]

The apparatus of the present invention made for this purpose has a test piece continuum gripping mechanism for gripping a material test strip continuum and a test piece continuum gripping mechanism for material testing.
While holding the one-piece continuum, pick up the test piece
Switch is used to intermittently feed the test piece continuum gripping mechanism.
Inter-specimen intermittent feed mechanism with a horizontal feed screw that is rotated by a motor, and a vertical feed net that is also rotated by a motor.
It is supported by a cutter support plate that moves up and down by a jig and can freely move in and out to cut the four-circle frame part between the test pieces of the test piece continuum.
And a pair of chucks for gripping the grip portion of the test piece separated by the cutter at that position and displacing at least some of the displacement to perform a tensile test on the test piece. Each test piece that composes
It is designed to automatically and continuously perform a tensile test.
It is characterized by

[0007]

Operation: The material test piece continuum is gripped at its upper part by the test piece continuum gripping mechanism, and the material test piece continuum is
The test piece itself is intermittently fed by the intermittent feeding mechanism by the pitch. At the stop position of the intermittent feeding movement of the material test piece continuous body, the both end gripping portions of the test piece are gripped by the pair of chucks. In order to separate the test piece gripped by the pair of chucks from the test piece adjacent thereto, the cutter is operated to cut the four-sided frame portion between the test pieces adjacent to each other. After that, some of the chucks are displaced and the chucked test piece is pulled to perform the test. When the test of this test piece is completed, the inter-test-piece intermittent feeding mechanism operates, sends the adjacent test piece to a pair of chuck positions, chucks this, and cuts between the adjacent test piece by a cutter, Perform the same test.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The apparatus of the present invention is shown in FIGS. 1 and 2, and 20 and 21 in the drawings are fixed parts provided on a mount (not shown). The upper and lower immovable parts 20 and 21 are attached to the pair of chucks, each of which is composed of a lower chuck 22 and an upper chuck 23 similar to those used in a known tensile tester, and at least one or both of these chucks are mutually connected. It is displaced so that the material test piece is subjected to a tensile test.

In the figure, reference numeral 24 denotes a test piece continuum gripping mechanism, which has a plurality of gripping portions 25, 25 for gripping the four-circumferential frame portion 14 above the test strip continuum 10. The gripping portion 25 is the air cylinder 2.
The test piece continuum 10 can be gripped by 6, 26. This test piece continuum gripping mechanism 2
No. 4 is supported by a test piece intermittent feed mechanism 27 so that it is intermittently fed and operated. Therefore, the test strip continuum gripping mechanism 24 has support strips 28, 28 on its upper portion, is supported and guided by the horizontal guide 29 of the inter-test strip intermittent feed mechanism 27, and is screwed into the horizontal feed screw 30.

The inter-specimen intermittent feed mechanism 27 has the horizontal guide and the horizontal screw 30 supported by a support member 31 fixed to the upper fixed portion 21, and a motor 32 for rotating the horizontal feed screw 30. Have.

A pair of vertical guides 33 hang vertically downward on a support member 31 fixed to the upper fixed portion 21.
And a vertical feed screw 34, and a motor substrate 36 is fixedly mounted on the lower end of the vertical guide 33.
A motor 3 that has a guide member 35 that guides the lower four-circumferential frame portion 14 of 0 and drives the vertical feed screw 34 to rotate.
7 is fixed.

In the figure, 38 is the four-sided frame portion 1 of the test piece continuum 10.
A cutter that cuts 4 is guided by the vertical guide 33, supported by a cutter support plate 39 that moves vertically by screwing with a vertical feed screw, and can be moved in and out by an air cylinder 40, and a test piece continuum at a protruding position. The four peripheral frame portions 14 of 10 are cut.

In FIG. 1, the test strip continuum 10 is gripped by the test strip continuum gripping mechanism 24.
The grip 11 of the test piece at the left end of 0 is the upper and lower chucks 22,
The state of being chucked by 23 is shown.
In the illustrated embodiment, the four-sided frame portion 14 at the left end of the test strip continuum 10 is cut, but in this state, it may not be particularly cut. While the test piece at the left end is chucked, the motor 37 is operated to rotate the vertical feed screw 24 to vertically move the cutter support plate 39 and the cutter 38, and the air cylinder 40 is operated to operate the cutter 3.
8 is projected, and the gap between the test piece chucked by the upper and lower chucks 22 and 23 and the adjacent test piece is cut. Then, the upper and lower chucks 22 and 23 are displaced, and the test piece is subjected to a tensile test. Thus, when this pulling test is completed, the chuck abandons the test piece, operates the motor 32 of the inter-test piece intermittent feed mechanism 27 to rotate the horizontal feed screw 30, and causes the test piece continuum gripping mechanism 24 to move to the next test in the figure. The pieces are intermittently fed until they face the chucks 22 and 23, and the chucks 22 and 23 operate at the fed positions to chuck. Along with this, the cutter moves up and down in the same manner as described above to cut between the next test piece and the tensile test.

[0014]

As described above, according to the material testing apparatus of the present invention, the material test can be performed by the material test piece continuum , and the material test pieces constituting the material test piece continuum can be sequentially processed.
It has the effect that it can be automatically tested continuously in succession , is effective, and is easy to handle.
