Hydraulic Rivetless Clinching Machine | TDC Duct Flange Fastener

Product Description

The JACK-AIVA Hydraulic Rivetless Clinching Machine joins two or more sheet-metal layers through cold pressing. Also described as a stationary hydraulic fastener, it is used for TDC flange ductwork and related sheet-metal connections without separate rivets at the clinched joint.

The punch and die must be selected for the sheet stack and flange access. The reference website specification describes a 4 mm round head for three-layer stacks of 0.6 mm, 0.8 mm or 1.0 mm per sheet. The standard head arrangement is listed for TDC flange heights not exceeding 30 mm.

Production Process

Select suitable tooling → Align sheet layers → Position the flange in the tooling → Hydraulic cold pressing → Release and inspect the joint

The tool forms the connection through cold pressing. The operator must position the workpiece, and joint suitability depends on the material, layer combination and tooling.

Key Features

Technical Parameters

Choosing the Clinching Tool

Specify each sheet layer separately rather than only the combined thickness. The 4 mm standard-head reference and its listed sheet stacks are not universal ratings. A separate documented tooling option uses a 6 mm round head for a 1.2 + 1.2 + 1.2 mm stack; confirm the actual tool set in the quotation. Flanges above 30 mm require a head length suitable for access.

Machine Configuration

Stationary machine frame

Supports the hydraulic joining operation and the workpiece access area.

Hydraulic pressing unit

Applies the pressing action needed to form the connection.

Interchangeable punch and die

Tool geometry is selected for the required sheet stack and joint.

Operating control

The pictured equipment includes a foot-operated control; the final operating arrangement is specified with the machine.

Applications

• TDC flange ductwork connections
• HVAC sheet-metal fabrication
• Compatible multi-layer sheet joints requiring rivetless fastening

Why Choose This Machine?

Cold-press joining provides an alternative to separate rivets for suitable sheet-metal connections. Matching the tooling to sheet thickness and flange height makes the machine configuration specific to the required joint.

Information Required for Quotation

• Material grade and surface coating
• Number of layers and thickness of each layer
• TDC flange height and section drawing
• Joint position and required tool access
• Required joint performance and inspection method
• Production volume and factory power supply

FAQ

Does the process use separate rivets?

No. The documented stationary machine joins sheet layers through cold pressing without separate rivets.

How many sheet layers can be joined?

The source describes two or more layers, with tooling selected for the actual stack.

What is the standard flange height limit?

The reference standard head is suitable for TDC flange heights up to 30 mm. Taller flanges need a longer head arrangement.

Is one tool suitable for every thickness?

No. Tooling must be matched to the layer thicknesses. Provide the individual sheet specifications when ordering.

Are motor power and pressure fixed for every machine?

Those values are not specified in the supplied stationary-machine description. They should be confirmed for the quoted configuration.
