Description
Yangli Pneumatic Sheet Clamp for CNC Turret Punch Press
The Yangli Pneumatic Sheet Clamp is an important workholding component used on CNC turret punch presses to securely grip sheet metal during automatic feeding, positioning and punching operations.
The clamp is powered by compressed air, allowing it to open and close quickly according to the CNC machine cycle.
During production, the sheet clamp holds the sheet firmly while the machine feeding system moves the workpiece along the X and Y axes. Accurate and reliable clamping is essential because any unwanted movement between the sheet and clamp can affect hole position, repeatability and overall punching accuracy.
WYS MACHINERY supplies different clamp configurations for Yangli CNC turret punch presses, including both the older round-body design and the newer square-body design shown in the product images.
Old Type & New Type Designs
Two common Yangli pneumatic sheet clamp designs are shown.
Old Type – Round Body
The older version features a round pneumatic cylinder structure.
It is commonly found on earlier Yangli CNC turret punch press models and uses compressed air to actuate the clamping mechanism.
New Type – Square Body
The newer version uses a more compact square-body pneumatic structure.
Although the external appearance is different, its primary purpose remains the same: securely clamp the sheet during automatic feeding, positioning and repositioning.
When replacing an existing clamp, the correct type should be selected according to the machine model, installation structure and original clamp design.
Main Function
The main function of the pneumatic sheet clamp is to maintain a reliable mechanical connection between the sheet metal and the machine positioning system.
During CNC punching, the process can be summarized as:
Clamp Sheet → Move Sheet → Position Hole Location → Punch → Reposition → Continue Punching
If the sheet is not held securely, positioning errors can accumulate during repeated movement.
A properly functioning pneumatic work clamp helps maintain stable workpiece position and supports accurate high-speed punching.
Pneumatic Operation
The clamp uses compressed air as its power source.
When the machine control system sends a signal, compressed air actuates the clamp mechanism to either:
Close and grip the sheet
or
Release the sheet for repositioning or loading
Pneumatic actuation provides fast response and is well suited to repetitive CNC punching cycles.
Compared with purely manual clamping, pneumatic clamps can integrate directly with the machine's automated feeding and control system.

Role in Sheet Feeding & Positioning
The sheet clamp works together with the CNC punch press feeding system.
During production, the machine feeder moves the clamped sheet according to the programmed coordinates.
The clamp therefore plays an important role in:
- Sheet feeding
- Workpiece positioning
- Hole coordinate accuracy
- Repeated punching
- Automatic repositioning
- Large-sheet processing
- Continuous CNC production
This makes the clamp not only a simple gripping component, but also an essential part of the turret punch press workholding and sheet positioning system.
Relation to Sheet Repositioning
For large sheets, the machine may need to perform a repositioning cycle when the original clamp position can no longer cover the remaining punching area.
During repositioning, the clamp may release and move to a new gripping position before clamping the sheet again.
The pneumatic sheet clamp therefore works closely with the machine's repositioning mechanism.
This relationship is especially useful for website SEO because it naturally connects this page with keywords such as:

Typical Applications
The Yangli pneumatic sheet clamp is suitable for:
- CNC turret punch presses
- Sheet metal automatic feeding
- Sheet positioning
- Workpiece clamping
- Large-sheet punching
- Automatic repositioning
- High-frequency CNC punching
- Sheet metal fabrication
- Electrical cabinet production
- Metal enclosure manufacturing
- Punch press maintenance
- Clamp replacement
- CNC punch press spare parts repair
Replacement & Model Identification
Different Yangli CNC turret punch press models may use different clamp structures.
Before replacement, customers should confirm:
- Machine model
- Production year
- Old or new clamp type
- Installation dimensions
- Mounting hole position
- Pneumatic connection
- Clamp jaw structure
- Original part photos
If the machine model is unclear, customers can provide detailed photos of the existing clamp and mounting position for identification.
WYS MACHINERY can help match the appropriate replacement version.
Old Type vs. New Type Replacement
Because the old and new Yangli pneumatic clamps have different external structures, they should not automatically be considered interchangeable.
The correct replacement should be confirmed according to:
- Mechanical mounting
- Pneumatic interface
- Clamp height
- Jaw position
- Sheet holding level
- Machine feeder structure
For this reason, the two versions are best presented on the same product page as different configurations, rather than publishing two almost identical SEO pages.
