Cold stamping mould frame for electronic type universal material testing machine

Abstract

A cold stamping die carrier used in an electronic universal material testing machine relates to a mechanical and dynamic experimental apparatus. The cold stamping die carrier is used for arranging a cold stamping die on the electronic universal material testing machine so as to perform actual measurement on the dynamics rule of a sheet material in the cold stamping process. Stamping equipment has high production efficiency, but actual measurement on important load-displacement curves by the electronic universal material testing machine in the stamping process is inconvenient. The electronic universal material testing machine can conveniently measure the load-displacement curves in the loading process, but the material to be measured is first machined into a sample with standard shape and specification at experiment, and the experiment can only be performed on simple deformation modes (such as stretching, compression and bending) while the experiment can not be directly performed on complex deformation modes (such as blanking and deep drawing) of the sheet material at cold stamping. A cold stamping die can be arranged on the electronic universal material testing machine and works reliably by the framework provided by the invention, thus facilitating the actual measurement of mechanics parameters of the sheet material in the cold stamping process.

Description

Technical field: [0001] The invention belongs to mechanical and mechanical experiment equipment. Through the device, the cold stamping die can be installed on the electronic universal material testing machine, so as to measure the mechanical law of the metal or non-metal sheet metal during the cold stamping process. Background technique: [0002] Cold stamping is at room temperature, using a mold installed on the stamping equipment (mainly a press) to apply a certain pressure to the stamped material to cause separation or plastic deformation, so as to obtain parts of the required shape and size (also called manufacturing A pressure processing method of parts or stampings). Because the commonly used material is sheet metal, it is also often called sheet metal stamping. The cold stamping die is a special tool used to realize the cold stamping process, and the mold base part has been standardized, which is called the standard mold base. The cold stamping die adopts a standar...

AI Technical Summary

Problems solved by technology

The electronic universal material testing machine is mainly used to measure the mechanical properties of metal or non-metallic materials. It can easily measure the load-displacement curve during the loading process, but the test material must be processed into a standard shape and specification in the experiment. Samples, and can only conduct experiments on several simple deformation methods such as tension, compression, and bending, and cannot directly conduct experiments on complex deformation conditions (such as blanking, deep drawing, etc.) of sheet metal in the cold stamping process
