Pneumatic Battery Electrode Sheet Trimming Machine Edge Cutting Machine

Product Overview

This pneumatic edge-cutting system is designed for trimming the top and side sealed edges of aluminum-plastic-film pouch cells after pocket forming. It combines cylinder-driven punching, sharp high-speed-steel cutting blades, and precision guided motion to produce a clean, repeatable trimming operation. The 300 mm cutter length supports production fixtures requiring a substantial cutting span, while the specified trimming accuracy of ±0.2 mm helps users maintain controlled finished-edge dimensions.

The equipment is suited to pouch-cell manufacturing and laboratory battery fabrication processes where post-forming edge management is required. An operator places the battery on the positioning plate with one hand and actuates the foot switch to complete the cut. Trimming width is defined around the customer-provided sample cell and its reserved top/side seal dimensions, then can be adjusted through the positioning stop edge.

Built around upper and lower blade mechanisms, a guide-post and guide-bushing assembly, and a battery positioning plate, this unit is configured for practical daily operation. Mold ball guide posts and guide bushings guide the upper blade with high precision, helping maintain zero clearance between the upper and lower cutting blades and supporting blade service life.

Key Features

• Pneumatic Punching Action: A cylinder-driven punching method delivers the cutting motion for top and side seal edge trimming. The pneumatic arrangement requires an air supply of at least 0.5 MPa.

• Controlled Trimming Accuracy: Specified trimming accuracy is ±0.2 mm. This defined tolerance supports users who need a repeatable edge-cutting step after aluminum-plastic-film pocket forming.

• 300 mm Compatible Cutter Length: The cutter is specified for a 300 mm cutting length. This provides a clear dimensional reference for matching the system to the intended pouch-cell format and fixture arrangement.

• High-Precision Blade Guidance: The upper cutting blade uses mold ball guide posts and guide bushings for guidance. This arrangement is intended to maintain zero clearance between upper and lower blades while promoting stable cutting alignment and working life.

• High-Speed-Steel Cutting Blades: Both the upper and lower cutting blades are made from high-speed steel. Their sharp cutting edges are paired with a blade hardness rating of HRC≥58 for a robust cutting interface.

• Customizable Edge Width: Cutting width is determined by the profiling fixture, based on the reserved dimensions of the top and side seals on the customer-supplied sample cell. A positioning stop edge also enables trimming-width adjustment during setup.

• Foot-Switch Operation: The cutting action is controlled by a foot switch. This simple operating sequence allows the user to hold the battery against the positioning plate and complete trimming by pressing the foot valve.

• Purpose-Built Positioning Structure: The mechanical assembly includes upper and lower blade mechanisms, a guide-post and guide-bushing mechanism, and a battery positioning plate mechanism. These dedicated elements support consistent placement and controlled blade movement.

• Integrated Electrical Controls: The electrical configuration includes a solenoid valve and foot switch, with AC220V/50HZ power and a 500W rating. This combines pneumatic actuation with straightforward electrical control components.

Why Choose This Product

• Dedicated post-forming function: This system is specifically configured for trimming top and side sealed edges after aluminum-plastic-film pocket forming, rather than relying on a generalized cutting arrangement.

• Precision-focused mechanical guidance: Mold ball guide posts and guide bushings guide the upper blade with high precision to maintain the stated zero-clearance relationship between the cutting blades.

• Durable blade construction: Upper and lower blades use high-speed steel, with cutter hardness specified at HRC≥58. This is a practical foundation for a demanding repetitive cutting interface.

• Format-responsive setup: The profiling fixture can be customized from the customer-provided sample-cell blueprint and reserved seal dimensions, while the positioning stop edge provides trimming-width adjustment.

• Straightforward workstation operation: One-hand placement on the positioning plate and foot-switch actuation provide a direct, easy-to-operate cutting sequence with defined pneumatic and electrical requirements.
