Applications

Used to reduce square or rectangular tube ends for furniture frames, storage racks and display systems, supporting telescoping, assembly and subsequent welding. Four-direction forming helps maintain end symmetry and reduce visible offset caused by one-sided compression.

  • Furniture Manufacturing
  • Shelving
  • Display Racks

Customization Scope

Dedicated dies can be designed for the section size, rectangular proportions, wall thickness, corner radius, material and target end geometry. High-appearance or non-standard sections require a drawing, tube samples and the mating component for fit verification.

Tube Processing / Swaging

How the Machine Works

Dedicated dies form square or rectangular tube from multiple directions. Section proportions, corner radius, weld-seam position and wall thickness influence material flow, so positioning and die clearance must control offset and surface marks.

Inputs Required for Selection

  • Incoming section, diameter or side size, wall thickness and length
  • Material grade, weld-seam position and incoming surface condition
  • Target end dimensions, formed length, finish and mating relationship
  • Tolerance, inspection method and required retained samples
  • Planned output, handling method, electrical supply and floor space

Configuration Options to Review

  • Workpiece-specific dies, positioning and support
  • Manual, semi-automatic or linked controls
  • Feeding, receiving and line integration
  • Local voltage, guarding and operator interface
  • Sample trials and parameter records for special parts

Trials and Acceptance

  • Inspect fasteners, lubrication, hydraulics, electrics and safety devices
  • Check no-load movement, control logic and emergency stops
  • Run material trials with the agreed workpiece
  • Measure critical dimensions and finish against drawings or samples
  • Confirm trial records, packing list and supplied information

Before Delivery and Installation

  • Confirm machine size, weight, unloading route and installation position
  • Prepare the specified power supply, foundation and working clearance
  • Check the main machine, dies, accessories and documents against the packing list
  • Complete safety and no-load checks before the first production trial

Maintenance Priorities

  • Check lubrication, hydraulic oil and fasteners according to the maintenance information
  • Remove debris and dust from dies, rolls or finishing zones
  • Record common settings, unusual noise, alarms and workpiece changes
  • Match machine identity, specification and photos before ordering a replacement

Frequently Asked Questions

Why can a square-tube end shift off centre?

Section variation, seam position, wall thickness and locating error can make material flow unevenly.

Can square and rectangular tube share tooling?

The aspect ratio and corner radius normally require matched tooling rather than pressure adjustment alone.

Success.
