Suppressing Slippage at the Root Cause in Instrument Micro Screws
2026,04,01
The pressure ring is a key component in preventing workpiece wrinkling and slippage during the stretching process. For
Instrument Micro Screws, its anti-slip design requires a combination of surface treatment and pressure control.
Pressure Ring Surface Optimization: For the working surface of the pressure ring in contact with the workpiece, Instrument
Micro Screws can use a rubber composite layer (high-temperature resistant silicone material, suitable for high-temperature stretching scenarios) or a textured finish.
The coefficient of friction of the rubber layer is 2-3 times that of metal, effectively increasing gripping force. For high-temperature environments (such as hot stretching), a ceramic coating texture is used, combining anti-slip and heat resistance.
Adjustable Pressure Force System: Insufficient pressure force will cause workpiece edge slippage, while excessive force can easily cause workpiece breakage.
Electronic vehicles use a spring-air cushion combination system or a hydraulically adjustable device to dynamically adjust the pressure force according to the workpiece thickness and stretching depth.
For example, when stretching a 1mm thick aluminum plate, the pressure force is set to 500-800N; when stretching a 3mm thick steel plate, it is adjusted to 1500-2000N to ensure a balance between pressure and friction.
