What is a Joggle In Sheet Metal

What is a Joggle In Sheet Metal?

A joggle in sheet metal is a small offset or bend to create an overlapping joint on a flush surface. The offset bending process creates two opposite bends with equal angles in a single action. The joggle bends are in opposite directions and less than 90°.

It creates the jog bends on many types of sheet metal bending, including aluminum, Mild steel, galvanized steel, and stainless steel. The joggle sheet metal tool is commonly used in sheet metal industrial works, such as Electrical enclosures, aircraft, and automobiles.

 

What is the purpose of Joggle?

The purpose of a joggle is to allow for clearance to create sheet metal joggle joints to reinforce structures. such as in sheet metal work or reinforced concrete structures. Steel joggles in sheet metal are used in steel rebars to provide a secure connection between the rebar and the concrete, facilitating the transfer of loads more efficiently.

 

What is the process of joggle forming?

A joggle bending is an offset bending process that creates two opposite bends with equal angles in a single action, It means creating a small Z-shape bend profile. Joggle forming is when multiple bends are made on a sheet metal creating an angle less than 90 degrees.

This joggle forming process mostly involves placing a sheet metal between a punch and a die. The inside joggle radii should be approximately the same as used for straight bending. A joggle press brake clamps sheet metal between two dies to create a joggled joint. When the press brake applies pressure to the sheet metal, the top die pushes down to make a bend at the point where it contacts the sheet metal. The joggling process aims to strengthen and secure connections for safety and reliability.

 

Applications of Joggles:

1. Aircraft and Automotive Industry: Often used in fuselage or body panel assembly to create smooth overlaps without additional fasteners.
2. Electrical Enclosures: Allows for cleaner joins and wiring clearances inside boxes and panels.
3. Joining and Sealing: Improves fit and sealing in joints, which is especially useful in applications requiring watertight or airtight assemblies.
4. Reinforcement: Increases structural strength where two sheets meet, improving stability and appearance.

How to make a joggle in sheet metal?

Joggle in sheet metal refers to a process that creates a step or a projection on the edge of a metal piece to provide a secure joggled joint when assembled with another piece. Normally Small Joggles formed in sheet metal work from 0.7mm to 3mm thick and up to a width of 140mm.

How to joggle sheet metal with custom offset dies?

Step 1: To define joggle in sheet metal after completing joggle tools to ensure quality,  the sheet metal joggle tool will be tested to make a joggle in sheet metal on the joggle bender machine.

Step 2: we will check each dimension with a vernier caliper based on the drawing provided.
