Faulty bending testing equipment with interchangeable bending mold socket

main purpose

1. Realize rapid changeover and improve equipment utilization: When testing multiple models of products in research and development or quality inspection, there is no need to purchase complete machines or carry out lengthy mechanical modifications for each product. Simply replace the corresponding mold socket module to start new testing immediately, greatly reducing downtime.

2. Ensure the neutrality and repeatability of testing: The card holder adopts precision positioning design (such as cone positioning, high-precision pins) to ensure that the bending center line and force axis of the sample strictly coincide with the main axis of the equipment after each mold change, fundamentally ensuring the high comparability of data between different batches of testing.

3. Protecting the device body and simplifying operation: All clamping and positioning functions for samples are integrated into replaceable molds, avoiding damage to the precision moving parts of the host due to frequent adjustments. Operators only need to receive simple mold loading and unloading training, reducing the threshold for use.

Typical technical parameters

• Interface standard: Adopt quick change interface, such as pneumatic locking, manual knob locking or hydraulic locking, with a locking force usually greater than 5kN.

• Positioning accuracy: The repeated positioning accuracy is better than ± 0.02mm, ensuring consistency during each installation.

• Load bearing capacity: The design load needs to match the testing capacity of the equipment (such as 500N or 2kN).

• Interface size: Standardized installation flange size (such as Φ 100mm, 150mm × 150mm square plate).

• Material and Hardness: The main body is made of high-strength aluminum alloy or stainless steel, and the hardness of the positioning components is ≥ HRC 60, ensuring wear resistance and long-term accuracy.

product structure

A complete interchangeable system typically consists of two parts:

1. Host side base (male head): fixed on the moving and static crossbeams of the equipment. include:

• High precision positioning mechanism: such as hardened steel cone sleeve or precision positioning pin.

• Quick locking mechanism: such as pneumatic piston, eccentric cam or high-strength bolt.

• Signal and pneumatic interface: used to connect possible sensors (such as micro switches) or pneumatic grippers on the mold.

2. Mold end module (female head): refers to the personalized part that actually holds the sample. include:

• Matching positioning interface: a conical surface or pin hole that fits snugly with the base.

• Sample clamping mechanism: customized V-shaped blocks, imitation card slots, pneumatic fingers, etc. according to the product.

• Lightweight structure: usually adopts aluminum alloy frame, which is convenient for manual handling and installation.

Product performance

1. Transformation efficiency: Mold replacement can be completed within 1-3 minutes, which is more than 10 times more efficient than traditional bolt fixing methods.

2. Rigid transmission: Although it is a detachable connection, through positioning and surface contact design, its connection rigidity is close to an integrated structure, ensuring that the test force is transmitted without loss.

3. Excellent error proofing: The mold and socket usually have keyways or codes to prevent incorrect installation.

4. Long term accuracy maintenance: The key positioning surface has no relative sliding, minimal wear, and with regular calibration, it can ensure that the equipment maintains high accuracy after years of use.

Collaboration with temperature control system

When integrating a temperature control system into the device, special requirements are placed on the mold socket:

• Material thermal stability: The materials of the mold and the card holder need to have similar coefficients of thermal expansion or be thermally compensated during design to prevent loss of positioning accuracy or locking failure due to expansion/contraction differences at high temperatures (such as+150 ℃) or low temperatures (such as -40 ℃).

• Thermal isolation design: The base of the card holder sometimes needs to be connected to the equipment crossbeam with insulation materials to reduce the thermal bridge effect, reduce the energy consumption of the temperature control system, and protect the host sensors from temperature effects.

meet the standard

This design directly supports and meets the efficiency and standardization requirements of modern high standard testing laboratories:

• Support for multi standard testing: By quickly replacing molds that meet different sample sizes specified by standards such as EIA-364, IEC, JIS, a single device can easily meet multi standard compliance testing.

• Compliant with laboratory management standards: Convenient mold management (numbering, calibration records) meets the requirements of ISO/IEC 17025 and other standards for traceability and control of testing equipment.

• Improving data consistency: ensuring consistent conditions for conducting the same test with different operators and at different times, resulting in more reliable data.

Application field

This design is particularly valuable for fields with diverse products and frequent testing requirements:

• Connector and Cable Industry: Used for frequent replacement and testing of connectors with different PIN numbers and spacing, as well as cables of various wire diameters.

• Research and development of consumer electronics products: Quickly test the bending life of various new forms of products such as mobile phone hinges, watch straps, headphone plugs, etc.

• Automotive parts supplier: Conduct small batch sampling durability testing for wiring harnesses, switches, sensors, and actuators of different vehicle models.

• Third party testing laboratory: Faced with diverse sample submissions from numerous customers, it can quickly respond, improve service capabilities and throughput.

Convertible bending mold socket

This is the core hub for achieving flexibility, efficiency, and accuracy in device testing. It is a standardized and high-precision mechanical interface platform that allows users to quickly and accurately replace bending molds or sample fixtures of different specifications within minutes. Its core value lies in transforming specialized testing fixtures for specific products into plug and play "modules", enabling a host to seamlessly adapt to a wide range of testing needs from micro connectors to thick cable harnesses.
