Disc Spring Sorting Testing Machine
Category：Torsion Testing Machine
Introduction
The Disc Spring Sorting Testing Machine is designed for accurate measurement and automatic sorting of disc springs based on their mechanical performance.The machine can precisely measure the static compression strength of disc springs under compressed conditions and evaluate their ability to withstand static loads, such as measuring the load generated at a specified deformation.It can also determine key performance parameters including spring stiffness (elastic modulus), maximum deformation, and residual deformation. The equipment supports testing the force at a specified deformation or measuring the remaining height/deformation under a specified test force.By setting the qualified range of spring force or height parameters, the machine can automatically perform force-based or height-based sorting, improving inspection efficiency and ensuring consistent product quality. It is widely used in disc spring manufacturing, automotive components, machinery, and precision spring quality control applications.

Main Structure and Functions
Main Frame:
Adopts a gantry-type structure, providing a stable support platform and installation base for the testing machine.
Transmission System:
Mainly consists of a reducer, precision ball screw mechanism, and guiding components. It transfers power to the compression plate, enabling accurate upward and downward movement.
Drive System:
Composed of an AC servo speed controller and servo motor, providing stable power output and driving the testing system.
Measurement and Control System:
The test force measurement and control system consists of a high-precision load cell, signal amplifier, and related components. The displacement measurement system uses a photoelectric encoder to achieve computer-based display, control, data acquisition, and processing functions.
Safety Protection System:
Includes specimen breakage stop protection, overload protection, crosshead limit protection, over-current protection, over-voltage protection, and overspeed protection to ensure safe and reliable operation.
