Bike Tube Bender Equipment丨JK-04 Machine Energy Hydraulic

The JK-04 is a hydraulic tube bender equipment model designed specifically for bicycle handlebar production. It bends round tubes into the shapes required for different handlebar designs, helping frame and component factories keep geometry consistent across large production runs.

Applications in Bicycle Handlebar Production

1. Suitable Handlebar Types

The JK-04 targets the range of handlebars seen in everyday bicycle production. Typical handlebar types include:

• City and trekking bike handlebars
• Flat bars for MTB and hybrid bikes
• Bars for BMX and urban bikes
• Other custom steel or alloy handlebars within the designed tube range

For each handlebar type, the machine supports the main bends that define rise, sweep, and overall shape, so engineers can match existing models or introduce new designs.

2. Tube Sizes and Materials

Handlebar performance depends heavily on tube dimensions and material, so the JK-04 is built for commonly used handlebar tubes. Typical applications cover:

• Round tubes used for bicycle handlebars
• Steel and alloy tubes within the bending range of the machine
• Wall thicknesses chosen by the customer for strength and ride comfort

Key Features for Production and Engineering Teams

1. Hydraulic Bending for Consistent Handlebar Geometry

Hydraulic power gives the JK-04 a stable bending force over repeated cycles. For handlebar production, this helps:

• Keep left and right sides of the bar aligned
• Maintain target bending angles over long runs
• Reduce variation that could affect handling, rider comfort, or appearance

Consistent geometry also simplifies downstream operations such as welding, grinding and surface finishing.

Integration with Existing Bicycle Production Lines

1. Upstream and Downstream Processes

The JK-04 can be integrated into both standalone handlebar lines and mixed bicycle production environments. Common surrounding processes include:

• Tube cutting and end preparation
• Hole punching or slotting when required by handlebar design
• Welding of additional parts, such as cross braces for BMX bars
• Grinding, polishing and surface treatment

By placing the tube bender equipment close to these processes, factories can reduce handling time and keep material flow simple.

Manufacturing Background and Support

At Jui Chih, we build the JK-04 based on our long experience in bicycle machinery and tube processing equipment. This background helps us clearly understand:

• Common handlebar standards and dimensions
• Typical issues when bending tubes for handlebars
• Practical requirements of factories running multi-shift production

We assemble each JK-04 machine with careful checks on structural alignment, smooth motion, and hydraulic performance. Before shipment, we carry out sample bending tests to make sure the machine performs as expected in real production conditions.
