Description

试样延伸率和断面收缩率测量的辅助装夹装置 Auxiliary clamping device for measuring sample elongation and area reduction

技术领域 technical field

背景技术 Background technique

It provides reliable mechanical performance parameters of materials for machinery manufacturing, civil engineering, metallurgy and various other industrial sectors, so as to facilitate the rational use of materials and ensure the machine (structure) and Its parts (components) work safely and reliably.

延伸率(δ)和断面收缩率(ψ)是材料力学性能试验中两个重要的指标。当试样较短时,可将试样拼合后用左手顶紧,右手用游标卡尺测量,但由于试样拉断后断口毛刺较多易划伤手指,工作效率低。对于长试样,断后对接在一起,标线有时不在上方,给测量带来较大困难。带头试样根本无法测量;或由于试样拉断后的两段,其轴线不位于一条直线上,造成测量误差。为满足试样力学性能参数的测试,需要设计专用工具。Elongation (δ) and reduction of area (ψ) are two important indicators in the mechanical performance test of materials. When the sample is short, you can put the sample together and tighten it with your left hand, and measure it with a vernier caliper with your right hand. However, since the sample is broken, there are many burrs on the fracture surface, which is easy to scratch the fingers, and the work efficiency is low. For long samples, butt together after breaking, the marking line is sometimes not on the top, which brings great difficulties to the measurement. The sample with the head cannot be measured at all; or because the axes of the two sections of the sample are not located on a straight line after the sample is broken, measurement errors are caused. In order to meet the test of the mechanical performance parameters of the sample, special tools need to be designed.
