一种制作金属氧化皮拉伸试样的模具
摘要：
本实用新型公开了一种制作金属氧化皮拉伸试样的模具，其包括对称设置的形状相同的左侧板、右侧板以及设于两侧板下部的底板，底板与左、右侧板通过螺栓固定连接；左侧板一侧开设有圆柱槽，上部开设有半圆形的凹槽，左、右两个侧板中间部位形成圆柱形容置槽，容置槽的上部逐渐收缩形成一用于浇注环氧树脂的浇口。采用本实用新型可制作出一种新型的拉伸试样，该拉伸试样的两端通过本模具的容置槽可由环氧树脂形成夹持部，进行拉伸试验时将拉伸夹头夹持住该夹持部，即可进行拉伸试验，防止了氧化皮被直接夹碎；容置槽的上部逐渐收缩，形成一直径较小的浇口，这样成型的夹持部与金属氧化皮测试部圆滑过渡，可防止其在拉伸机夹头中断裂。
摘要（英）：

The utility model discloses a die for manufacturing a tensile sample of a metal oxide skin. The die comprises a left side plate, a right side plate and a bottom plate, wherein the left side plate and the right side plate are symmetrically arranged, and shapes of the left side plate and the right side plate are identical; the bottom plate is arranged at lower parts of the two side plates and fixedly connected with the left side plate and the right side plate through bolts; a cylindrical groove is formed in one side of the left side plate, and a semicircular groove is formed in the upper part of the side plate; a cylindrical accommodating groove is formed in the middle parts of the left side plate and the right side plate; and the upper part of the accommodating groove retracts gradually, so that a sprue used for pouring an epoxy resin is formed. With the adoption of the die, a novel tensile sample can be manufactured, clamping parts made of the epoxy resin are arranged at two ends, passing through the accommodating groove of the die, of the tensile sample, and when a tensile test is performed, ensile chucks clamp the clamping parts, so that the tensile test can be performed, the sprue with a smaller diameter is formed, the formed clamping parts are in smooth transition with metal oxide skin test parts, and the clamping parts can be prevented from being broken in the tensile chucks.
