Pneumatic Pincer

Introduction to Press Gripper 

pneumatic sheet metal grippers for transfer press system are run on compressed air and have the ability to pick up, place, hold and release objects while an action is being executed. Modular design could save assembly hours. Long life cycle, best price and flexible industrial assembly make Brisk grippers the best one available. Modular design could save assembly hours.

Different mechanisms could include:

A lateral direct coupling of a pair of pistons to guided opposing jaws moving opposite each other.
A design where opposing jaws are driven by a component of the piston rod riding on a cam surface portion of the jaws.
A rack, powered by pistons, driving a pinion that in turn employs a scotch yoke cam device to drive opposing jaws.
A rather complicated mechanism where the piston or one of its members drives a scroll mechanism similar to a machine lathe-chucking device.

Function and Purpose

Key Features

1. High Precision and Repeatability – Ensures consistent placement and alignment of parts.

2. Strong and Reliable Grip – Maintains firm holding force during high-speed press operations.

3. Compact and Lightweight Design – Suitable for robotic or multi-axis transfer systems.

4. Durable Construction – Typically made from hardened steel or aluminum alloys for long service life.

5. Customizable Gripping Jaws – Designed according to the shape, thickness, and material of the workpiece.

Working Principle

Press grippers commonly operate using pneumatic, mechanical, or servo-controlled systems:

• Pneumatic grippers use compressed air to open and close gripping fingers.

• Mechanical grippers rely on levers or cams synchronized with the press cycle.

• Servo grippers allow precise force and position control for delicate operations.

The gripping mechanism is synchronized with the press stroke, ensuring the gripper picks up the workpiece after one forming step and transfers it to the next die station smoothly and safely.

Applications

• Automotive manufacturing – Handling car body panels, brackets, and structural components.

• Appliance and electronics industries – Transferring stamped sheet parts.

• Aerospace and metal fabrication – Moving precision-formed components.

• Progressive and transfer press lines – Automating multi-stage stamping operations.

Advantages

• Improves efficiency and production speed in press operations.

• Reduces manual handling and enhances workplace safety.

• Minimizes scratches, deformation, and damage to materials.

• Enables high consistency and repeatability in part positioning.

• Compatible with fully automated robotic press systems.
