Abstract

The utility model relates to the technical field of stretching of the mechanical properties of metal materials, in particular to a special tool for stretching detection of metal material round test rods. In the prior art, when the metal material round test rods are stretched and tested, they need to be clamped up and down one by one, especially when the number of tested is large, resulting in repeated workload, and due to repeated clamping, the weight of each metal material round test bar Plumbibility is not guaranteed. The utility model is that before stretching the metal material round test rod, the upper and lower jaws of the tensile testing machine are respectively equipped with the special tooling for the metal material round test rod stretching, and the metal material round test rod does not need to be clamped one by one when the metal material round test rod is stretched. , Just place the metal round test rod in the card slot of the tooling, the metal round test rod will automatically find the center, ensuring the plumbness of each tested metal round test rod. The utility model reduces the workload caused by repeated clamping and improves the accuracy of detection data.

Description

Special tooling for tensile testing of metal material round test rods

technical field

The utility model relates to the technical field of mechanical performance stretching of metal materials, in particular to a special tool for mechanical performance stretching of metal material round test rods.

Background technique

At present, when the metal material round test bar is tensile tested, it is necessary to clamp the metal material round test bar up and down on the tensile testing machine one by one. The clamping caused the plumbness of each metal round test bar to be unguaranteed.

Contents of the invention

The purpose of the utility model is to provide a metal material round test bar tensile test special tool to solve the defects of the prior art, and is used for the test of various specifications of metal material round test bars on the tensile testing machine.

The technical scheme that the utility model solves its technical problem adopts is:

The special tooling for the tensile test rod of metal materials is composed of two cylinders, A and B. The A cylinder is a solid metal cylinder, and its function is for the clamping of the tensile testing machine; the central axes of the A and B cylinders are collinear; the B cylinder There is a card slot for the positioning of the metal material round test rod inside. The upper part of the card slot is used for the positioning of the metal material round test rod. The width of the card slot matches the diameter of the clamping part of the metal material round test rod; The detection part of the material round test rod protrudes; the upper and lower parts are transitioned by a conical surface, the large diameter of the conical surface matches the diameter of the clamping part of the metal material round test rod to be tested, and the small diameter of the conical surface matches the metal material to be tested The diameter of the detection part of the round test rod matches.

The beneficial effect of the utility model is that: when the metal material round test rods are stretched and tested, it is not necessary to repeatedly clamp the metal material round test rods up and down one by one, which reduces the repetitive workload; the metal material round test rods are placed on the tooling In the card slot, the metal material round test rod will automatically find the center, which ensures the plumbness of the tested metal material round test rod and improves the accuracy of the detection data.

detailed description:

In the figure: 1 special tooling for stretching metal material round test rods, 2 metal material round test rods;

As shown in Figures 1 to 7, before the metal material round test bar is stretched 2, a pair of metal material round test bar tensile special tooling 1 is clamped on the upper and lower jaws of the tensile testing machine, and only The metal round test rod 2 needs to be placed in the slot of the tooling, and the metal round test rod 2 will automatically find the center, ensuring the plumbness of each tested metal round test rod. Subsequently, the tensile detection of the metal material round test bar 2 is completed by loading the testing machine.
