Yawei Pneumatic Sheet Clamp for CNC Turret Punch Press

The Yawei Pneumatic Sheet Clamp is a workholding and sheet-feeding component used on CNC turret punch presses to securely grip the sheet during automatic movement and punching.

Powered by compressed air, the clamp opens and closes according to the machine control cycle.

Once the sheet is clamped, the machine feeding system moves the workpiece to each programmed punching position. During this process, the pneumatic clamp must hold the sheet securely so that the workpiece follows the feeder movement accurately.

Reliable clamping is important for maintaining:

• Punching position accuracy
• Repeatability
• Stable sheet movement
• High-speed feeding
• Automatic repositioning
• Consistent CNC production

This model is designed for Yawei CNC turret punch press applications and can be supplied as a replacement component according to the machine model and original clamp configuration.

Main Function

The pneumatic sheet clamp forms the mechanical connection between the sheet metal and the CNC feeding system.

During punching, the operating sequence can typically be understood as:

Clamp Sheet → Feed Sheet → Position → Punch → Reposition → Continue Processing

The clamp must remain stable during repeated acceleration, deceleration and directional movement of the sheet.

If the clamp does not hold the sheet securely, the workpiece may slip or shift, resulting in positional errors and reduced punching accuracy.

For this reason, the sheet clamp is a key component in the turret punch press workholding and positioning system.

Pneumatic Clamping Principle

The clamp is actuated by compressed air.

When pneumatic pressure is supplied, the internal mechanism drives the clamp to open or close depending on the machine control logic.

The main advantages of pneumatic operation include:

• Fast response
• Reliable repeated operation
• Easy integration with the CNC control cycle
• Suitable for high-frequency clamping
• Simple connection to the machine pneumatic system

This makes the pneumatic clamp well suited to automatic sheet metal punching production.

Role in CNC Sheet Feeding

The clamp works directly with the machine's feeder or sheet positioning mechanism.

During automatic punching, the CNC control system commands the feeder to move the sheet to predetermined coordinates.

The pneumatic sheet clamp keeps the workpiece mechanically connected to the feeder so that every programmed movement is transferred accurately to the sheet.

This makes the component relevant not only to clamping, but also to:

sheet feeding
workpiece positioning
CNC coordinate movement
punching repeatability
automatic sheet handling

Sheet Repositioning Function

When processing large sheets, the original clamping position may eventually reach the machine's travel limit.

At this point, the turret punch press can perform a sheet repositioning cycle.

During repositioning, the sheet is temporarily secured while the clamp releases, moves to a new position and grips the sheet again.

The pneumatic clamp is therefore an important part of the automatic repositioning system for large-format sheet metal processing.

This connects the product naturally with keywords such as:

• sheet repositioning clamp
• CNC punch press repositioning
• large sheet feeding
• turret punch workholding
• sheet handling system

Replacement & Model Matching

Different Yawei turret punch press models may use different sheet clamp structures.

Before ordering a replacement, customers should confirm:

• Machine model
• Production year
• Original clamp design
• Mounting dimensions
• Clamp height
• Clamp jaw structure
• Pneumatic port position
• Installation hole pattern

If the original part number is unavailable, customers can provide clear photos and measurements of the existing clamp.

WYS MACHINERY can help identify the correct replacement configuration.

Sheet Clamp vs. Feeder

这一点我建议在内部内容逻辑上区分清楚。

The sheet clamp is not the complete feeder.

The feeder is the machine mechanism that moves the sheet along the programmed axes, while the pneumatic sheet clamp is the gripping component that connects the sheet to that feeding system.

Therefore:

Feeder = Sheet Movement System
Sheet Clamp / Gripper = Workholding Component

这样可以避免 Google 或 AI 把这个页面错误理解成整套 feeder。
