O processo de encabeçamento a frio é um dos novos processos para a maquinagem sob pressão com menos ou nenhum corte
metal. É um método de processamento que utiliza a deformação plástica do metal sob a ação de
forças externas e, com a ajuda de moldes, redistribui e transfere o volume de metal para formar
as peças ou os espaços em branco necessários. O processo de encabeçamento a frio é o mais adequado para a produção de
elementos de fixação, tais como cavilhas, parafusos, porcas, rebites, cavilhas, etc.
Cross Slot Barrel Nuts are specialized fasteners designed for applications requiring secure, adjustable, and tool-free connections. Here’s a detailed description:
Features & Design:
-
Barrel-Shaped Body – Cylindrical form allows rotation within a pre-drilled hole, enabling multi-directional adjustment.
-
Cross Slot Mechanism – The top features a cross-shaped slot (two perpendicular grooves) that accepts a compatible flathead screwdriver or a cross-slot key for installation/removal.
-
Threaded Interior – Contains internal threads to mate with a machine screw or bolt, creating a strong clamping force when tightened.
-
Flanged or Non-Flanged – Some versions include an external flange to distribute load and prevent pull-through in softer materials.
-
Material Options – Typically made from steel, stainless steel, or brass para resistência à corrosão e durabilidade.
Vantagens:
-
Tool-Free Adjustment – The cross slot allows quick tightening/loosening without specialized tools (ideal for field adjustments).
-
360° Rotation – The barrel design lets the nut pivot, accommodating misaligned holes or angular adjustments.
-
Secure Grip – Threads resist loosening under vibration (common in automotive, furniture, or machinery).
-
Low Profile – Sits flush or semi-flush when installed, saving space.
Aplicações comuns:
-
Montagem de móveis – Used in flat-pack furniture for easy, tool-free tightening.
-
Automotive & Aerospace – Securing panels or components requiring frequent access.
-
Equipamento industrial – Adjustable mounts or fixtures.
-
Consumer Electronics – Internal fastening in devices needing serviceability.
Installation:
-
Insert the barrel nut into a pre-drilled hole (often with a shoulder or lip to retain it).
-
Align the cross slot for screwdriver access.
-
Drive the mating screw through the opposing part and into the barrel nut’s threads, tightening as needed.
