1. Product Overview

This machine is designed for formability testing of thin metal sheets/strips to evaluate plastic deformation performance, complying with standard GB/T 4156-2007 Metallic materials — Sheet and strip — Cupping test.

It adopts all-electric mechanical clamping & buffering structure. The punch presses into specimens and stops automatically once crack occurs. An optional camera is available for video playback to precisely read the cupping depth at the moment of crack initiation.

Test Principle

A spherical-end punch indents a specimen fixed between die and clamping die until a through crack generates. The indentation depth of the punch is defined as cupping value, which reflects the ductility of sheet metal. Specimen is clamped with 10kN clamping force, and cupping depth (mm) is recorded after penetration cracking.

3. Features & Performance

Automatic load control for easy operation.
Load cell ensures accurate and reliable force reading.
Computer controls whole test process per national standard; displays real-time data and force-time curves with automatic data processing.
Complete data storage and file management function for post-processing.
Equipped with printer for test report output.
Multi-level safety protection:
- Overload protection: unloading automatically when load exceeds rated value by 2%~5%
- Limit travel protection: motor stops when piston reaches stroke limit

4. Core Advantages

Servo motor constant-speed loading driven by PC; stepless adjustable pre-set punching speed.
Independent motor-driven clamping with adjustable clamping force and synchronous digital display.
Spoke-type load cells replace traditional hydraulic sensors; high-precision encoder measures cupping depth for superior accuracy and stability.
Quick-change fixture and easy specimen loading; one-button automatic clamping and full-auto testing. System auto stops upon force drop caused by cracking; peak value automatically recorded.
Automatic report generation, curve plotting and auto homing after each finished test.
