عملية الرأس على البارد هي واحدة من العمليات الجديدة للتشغيل الآلي بالضغط ذات القطع الأقل أو بدون قطع
المعدن. وهي طريقة معالجة تستخدم التشوه البلاستيكي للمعدن تحت تأثير
قوى خارجية، وبمساعدة القوالب، تقوم بإعادة توزيع ونقل حجم المعدن لتشكيل
الأجزاء أو الفراغات المطلوبة. عملية الخراطة على البارد هي الأكثر ملاءمة لإنتاج الأجزاء القياسية
أدوات التثبيت مثل البراغي والبراغي والصواميل والمسامير والمسامير والدبابيس وغيرها
A مسمار سلك الأمان Half thread is a specialized fastener designed to secure components in critical applications where vibration or movement could cause loosening. Here’s a detailed description:
الميزات:
-
Half-Threaded Design:
-
The bolt has a threaded portion (typically near the head) and a smooth shank section.
-
The unthreaded portion provides shear strength, while the threaded section allows for secure fastening.
-
-
Safety Wire Hole:
-
A small drilled hole (usually near the head or at the threaded end) allows for the insertion of safety wire (locking wire).
-
The wire is looped through adjacent bolts or a fixed structure to prevent rotation and loosening.
-
-
المادة:
-
Often made from high-strength materials like stainless steel (A2/A4), alloy steel (grade 8.8/10.9), or titanium for corrosion resistance and durability.
-
-
Thread Type:
-
Common thread standards include metric (M-series) or imperial (UNC/UNF).
-
The threaded portion may be fully or partially engaged depending on the application.
- Safety wire bolt Half thread
-
-
Head Styles:
-
Available in hex head, socket head cap screw (SHCS), or other aviation/aerospace-specific designs.
-
التطبيقات:
-
Aerospace & Aviation: Engine components, landing gear, and rotor assemblies.
-
Automotive & Racing: High-vibration areas like suspension and drivetrain.
-
Industrial Machinery: Critical bolted joints subject to dynamic loads.
Safety Wiring Method:
-
The wire is threaded through the bolt hole and twisted tightly to an adjacent fastener, ensuring tension prevents rotation.
-
Proper wiring follows clockwise tightening direction to avoid loosening under torque.
This bolt ensures fail-safe security in high-risk environments where traditional locking methods (like nuts or washers) may fail.
