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.
A column with a square groove is a structural element that features a longitudinal (lengthwise) square-shaped channel or recess along its surface. This design can serve functional, aesthetic, or load-bearing purposes, depending on the application.
Caraterísticas principais:
-
Shape & Structure:
-
The column itself may be cylindrical, rectangular, or another cross-sectional shape.
-
The square groove is a recessed channel cut into the column, running parallel to its length.
-
The groove may be centered, offset, or repeated in a pattern (e.g., multiple grooves for fluting).
- Square slot with column
-
-
Purpose & Applications:
-
Aesthetic Design: Adds visual interest, often seen in architectural columns (e.g., decorative fluting in classical pillars).
-
Functional Use: Provides space for wiring, piping, or reinforcement bars in construction.
-
Weight Reduction: Grooves can reduce material usage while maintaining structural integrity.
-
Assembly & Alignment: Helps in fitting adjoining components (e.g., sliding panels or joining beams).
-
-
Materials:
-
Concrete: Used in construction for reinforced columns.
-
Metal (Steel/Aluminum): Common in industrial and mechanical applications.
-
Wood: Found in decorative or furniture design.
-
Composite Materials: For lightweight, high-strength needs.
-
-
Manufacturing Methods:
-
Machining: For metal or plastic columns (CNC milling, lathing).
-
Molding/Casting: For concrete, polymer, or metal columns.
-
Extrusion: Common for aluminum profiles with grooves.
-
Carving/Routing: For wooden columns.
- Square slot with column
-
Examples of Use:
-
Architecture: Fluted columns in Greco-Roman designs.
-
Engineering: Square-grooved shafts for keyway fittings.
-
Furniture: Decorative table legs or support beams.
-
Industrial: Guide rails with grooves for machinery alignment.
