Abstract

The present invention relates to a cup-shaped sample unloading apparatus and method. The apparatus comprises a steel wire rope, a high fixed pulley assembly, a low fixed pulley assembly, two fixing piles, a sample unloading guide post, a spring, a base and a positioning sleeve. The high fixed pulley assembly, the low fixed pulley assembly, the positioning sleeve and one fixing pile are fixed on the base from left to right, and the other fixing pile is fixed on a lower mould. An outer wall of the positioning sleeve is fixedly connected to the base. One end of the spring is fixed on the sample unloading guide post, and the other end is fixedly connected to the positioning sleeve, so that the sample unloading guide post vertically slides up and down inside the positioning sleeve. One end of the steel wire rope is fixed on one fixing pile, and the other end is successively wound on a pulley fastened on the top of the sample unloading guide post and the low fixed pulley assembly. The high fixed pulley assembly is connected to the other fixing pile. The present invention has an advantage of resolving a problem that a cup-shaped sample is apt to be stuck at a die and is difficult to be unloaded in experiments such as a convex lug or secondary brittleness.

Description

technical field [0001] The invention belongs to the field of measuring the formability of metal plates, in particular to a cup-shaped sample unloading device and method. Background technique [0002] When carrying out the lug test or secondary processing embrittlement test, it is necessary to punch the disc sample into a cup-shaped sample. Due to the impact of springback on the formed sample, especially the high-strength steel, the formed sample is particularly easy to jam. on the die. Manually using a copper rod to smash the sample downward will lead to different degrees of deformation of the bottom of the sample cup, which will affect the measurement of the lug test value and the follow-up test of secondary processing embrittlement. Second, for equipment of 100 tons and above , Manually need to climb up and down the equipment, which is time-consuming and laborious, and it is not safe. Therefore, there is a need for a device and method that can easily remove the cup-shape...
