Abstract

The invention belongs to the technical field of copper bar test, and particularly discloses a trapezoid copper bar stretch test method. The method comprises the steps of 1, preparing a stretch sample,taking two trapezoid copper bars on which needs to be performed a stretch test and two pieces of abrasive paper, wherein the surfaces of waist edges of the two trapezoid copper bars are fitted with each other, and putting the two pieces of abrasive paper between the two ends of the two trapezoid copper bars respectively; 2, preparing the test, moving the stretch sample to a to-be-tested area of astretch testing machine, and using a clamping head of the stretch testing machine to clamp the two ends of the two trapezoid copper bars; 3, performing the stretch test, applying action force to thestretch sample by the stretch testing machine, and collecting needed test data to determine stretch property of the trapezoid copper bars; 4, calculating the data, dividing the collected test data into two to obtain the stretch test data of one trapezoid copper bar. Compared with the prior art, the test method, when used for performing the stretch test on the trapezoid copper bars, has simple operation, is time-saving and labor-saving, and can obtain an accurate stretch result.

Description

technical field [0001] The invention belongs to the technical field of copper bar detection, and specifically discloses a trapezoidal copper bar tensile test method. Background technique [0002] Copper busbars, also known as copper busbars or copper busbars, are made of copper and have rectangular, chamfered (rounded) rectangles, trapezoidal, etc. long conductors. Copper bars are used in circuits to transport current and connect electrical equipment. effect. Copper busbar is a high-current conductive product, which is suitable for electrical engineering such as high and low voltage electrical appliances, switch contacts, power distribution equipment, and busway. It is also widely used in ultra-high current electrolytic smelting projects such as metal smelting, electrochemical plating, and chemical caustic soda. Electrical copper bars have the advantages of low resistivity and large bendability. [0003] After the copper bar is manufactured, it needs to be tested, mainly t...
