Description

Technical Field

[0001] The utility model mainly relates to the technical field of peeling test tooling, in particular to a tooling used for sample stretching. Background Art

[0002] Currently, more and more aluminum alloy materials are used in automobile production processes, and with them comes the use of some parts that are high in strength and not easy to bend. For common steel plates and deformable aluminum alloys, the samples can be easily bent for peeling tests. However, due to their high strength and low elongation, materials such as cast aluminum alloys and steel cannot be bent, so it is impossible to perform peeling tests on connectors with parts made of such materials by bending the samples. For connectors with parts made of such materials (cast aluminum alloys, steel, etc.), a peeling test needs to be performed by stretching. However, the prior art lacks a clamping tool specifically for performing tensile peeling tests on such connection samples (at least one part of the connection sample is made of a material that cannot be bent). Utility Model Content

[0003] The technical solution of the utility model aims at the technical problem that the existing technical solutions are too single, and provides a solution that is significantly different from the existing technologies. It mainly provides a tooling for sample stretching, which is used to achieve stable clamping of connected samples (the material of at least one part in the connected sample is a material that cannot be bent) to facilitate tensile peeling tests.

[0005] A tool for sample stretching, comprising a carrier plate for placing the sample and a pressing plate for pressing the sample, a pulling plate for connecting a stretching device being fixedly connected to the side of the carrier plate facing away from the pressing plate, and the pressing plate and the carrier plate are detachably connected.

[0006] Furthermore, the carrier plate and the pressure plate are fixedly connected by bolts, a first connection hole for the bolts to pass through is opened on the carrier plate in a region corresponding to the pressure plate, and a second connection hole for the bolts to pass through is opened on the pressure plate.

[0007] Furthermore, a clearance hole is provided in the middle of the carrier plate, the clearance hole is a waist-shaped hole, and an outwardly expanding arc-shaped area is provided in the middle thereof.

[0008] Furthermore, two opposite sides of the carrier plate are provided with a large notch and a small notch, and the two opposite sides of the carrier plate are symmetrically arranged.

[0009] Furthermore, the pulling plate is "T"-shaped, and a side of the transverse portion of the pulling plate facing away from the vertical portion is fixedly connected to the carrier plate.

[0010] Furthermore, a side of the pulling plate connected to the carrier plate is provided with an escape opening aligned with the position of the escape hole.

[0011] Furthermore, one side of the pulling plate connected to the carrier plate is formed with limit blocks clamped on two opposite sides of the carrier plate.

[0012] Furthermore, the pressing plate includes a first pressing plate and a second pressing plate, the first pressing plate and the second pressing plate have the same structure, and the first pressing plate and the second pressing plate are respectively used to press on two ends of the same part in the sample.
