specific Embodiment 2

[0053] Specific embodiment 2 of the flaring test tooling of the present application: The difference between this embodiment and specific embodiment 1 is that the main body and the lower protrusion are made of insulators, and a conductive circuit is connected between the upper protrusion and the pressure rod. The conductive loop is provided with a power supply and an indicator light, and when the lower pressing end of the pressure device contacts the pressing rod and the upper protrusion at the same time, the conductive loop is turned on, and the indicator light indicates that the pressing end is pressed in place.

specific Embodiment 3

[0054] Specific embodiment 3 of the flaring test tooling of the present application: The difference between this embodiment and specific embodiment 1 is that the main body is made of an insulator, and a conductive circuit is connected between the two upper protrusions, and a power supply is provided on the conductive circuit. And the indicator light, when the lower pressure end of the pressure device is in contact with the two upper protrusions at the same time, the conductive circuit is turned on, and the indicator light indicates that the pressure end is pressed down in place.

specific Embodiment 4

[0055] Specific embodiment 4 of the flaring test tooling of the present application: The difference between this embodiment and specific embodiment 1 is that there are no bolts and threaded holes on the main body, and when the pressure end contacts the main body, it indicates that the lower pressure end is pressed down in place.

Abstract

The invention relates to a flaring test tool. The flaring test tool comprises a support, wherein the support comprises a connecting piece, the connecting piece is provided with an indication upper endsurface, and the indication upper end surface is used for making contact with the pressure end of a pressure device to indicate that the pressure end is pressed downwards in place; the support further comprises a lower protruding part and a pressing rod, the lower protruding part is arranged on the connecting piece, the axis of the pressing rod extends in the vertical direction, and the pressingrod moves downwards in the axial direction under the pushing effect of the pressure end; an ejector core is arranged at the lower end of the pressing rod, is provided with a conical part and is used for extruding the upper part of a sample outwards in the circumferential direction when the pressing rod moves downwards to form a flaring in the upper part of the sample; and the connecting piece allows the pressing rod to penetrate through and guides the moving direction of the pressing rod. Whether the flaring amount of the sample meets the requirement or not can be visually and precisely judgedby judging whether the pressure end makes contact with the connecting piece or not, and the actual flaring amount of the sample is guaranteed to be consistent with a preset flaring amount, thereby guaranteeing the flaring test result is precise.

Description

technical field [0001] The invention relates to a flaring test tooling. Background technique [0002] The flaring test tooling in the prior art includes a flared top core. When performing a flare test on a sample, a pressure is applied to the flared top core toward the sample, so that the flared top core squeezes the sample, and the sample is subjected to pressure. After the extrusion produces flaring deformation to the preset flaring amount, check whether the sample has cracks. If cracks occur, it means that the sample has not passed the flaring test. Otherwise, it means that the sample has passed the flaring test. In the prior art, the judgment of the amount of flaring usually depends on the experience of the operator: perform a rough flaring operation on the sample, and then take the sample down to check the amount of flaring. If the amount of flaring is not enough, put it back The flaring test tool is installed and then the flaring operation is performed. Repeat the ab...
