Introduction

The clamping force is the main parameter that characterizes the specifications of the die-casting machine. At present, there are many methods to test the clamping force of the die-casting machine, and the results obtained by different methods are not the same.

If the test results are biased, it is easy to cause a variety of accidents and cause disputes and conflicts between equipment suppliers and buyers. Therefore, the market urgently needs Develop a unified clamping force test method and clearly define each step of the measurement.

This document is formulated to provide a basis for the clamping force test evaluation of the die casting machine industry, improve the reliability and comparability of the test results, and save Equipment manufacturing costs and standardize market order.

4 Test Principle

4.1 According to Hooke's law, when a solid material is subjected to force, the stress and strain (unit deformation) of the material are in a linear relationship, satisfying Hooke's law.

The material that does not conform to Hooke's law is called linear elastic material. The tie rod of the die casting machine is a linear elastic material. After the tie rod is subjected to force, according to Hooke's law, the
