Cylindrical Capacitor Case CNC Grooving Pre Sealing Machine

Product Overview

This system is a CNC grooving and pre-sealing machine engineered for cylindrical supercapacitor cases. It performs the critical case grooving and pre-sealing curl-forming operations using servo motor and screw-driven motion. The controlled approach distance and speed support accurate forming, stable dimensions, and a repeatable process without the rebound associated with pneumatic-cylinder compression resistance.

The equipment is suited to 60-series diameter battery and supercapacitor products, with diameter customization available. It supports manufacturers that require consistent case preparation before subsequent assembly processes. Operators can set grooving and sealing dimensions through the human-machine interface, allowing the unit to automatically and precisely adjust to the required production data.

Built around high-precision linear guide assemblies, a jacket-style holding arrangement, PLC control, and intelligent external guarding, this unit is designed for dependable industrial operation. Its stable clamping, high centering coaxiality, controlled forming sequence, and long tooling life help maintain process consistency under demanding repetitive production conditions.

Key Features

• Servo Screw Drive Precision: Grooving and sealing motions use servo motor screw drives for accurate control of feed distance and feed speed. This arrangement provides stable advancing motion and avoids the rebound behavior that can occur when compressed pneumatic cylinders encounter resistance.

• Programmable Dimensional Adjustment: Grooving and sealing dimensions can be entered through the human-machine interface. The equipment then automatically performs precise adjustment to the selected data, supporting efficient setup for the required product dimensions.

• Controlled Two-Stage Sealing Feed: The sealing head first advances rapidly, then changes to a slower speed as it reaches the pre-sealing curl-forming stage. This progressive motion supports careful, controlled edge forming rather than an abrupt pressing action.

• Jacket-Style Product Clamping: A jacket-type fixture holds the cylindrical product securely during processing. The stable restraint minimizes movement, maintains high centering coaxiality, and promotes uniform grooving and sealing results with good roundness.

• High-Precision Linear Guidance: Precision linear guide sets direct the feed motion during both grooving and sealing. The guided movement supports high process precision and stable formed dimensions over repeated operating cycles.

• Die Roller Grooving Method: The system uses a tooling roller approach for grooving. This forming method is matched to cylindrical supercapacitor case processing and is supported by a normal tooling service life of more than 5 million operations.

• PLC and HMI Control: PLC control and HMI display provide a clear operating interface for production settings and process interaction. The control architecture also provides a practical foundation for integration into automated manufacturing workflows.

• Intelligent External Safety Guarding: An external intelligent protective enclosure helps provide safe and reliable operation. The guarded construction is intended to protect the operating area while preserving convenient access for normal use.

• Industrial Mechanical Presentation: The unit combines a compact floor-standing footprint with a geometrically designed exterior intended for practical operation. Its layout supports a professional production environment where equipment access and stable installation matter.
