18650 Automatic Cylindrical Cell Hydraulic Crimping Machine

18650 Automatic Cylindrical Cell Hydraulic Crimping Machine 

This machine is an auto crimper that is specifically designed for sealing cylindrical battery cases. It has advanced features that ensure stable and consistent sealing quality. The four-step crimping process involves two trials for pre-deformation, a third trial for complete sealing and a fourth trial for case consolidation. The machine also has a user-friendly human-machine interface with a PLC touch screen control. It comes with a floor-stand enclosure that has transparent front and side openable windows, which allows for clear process monitoring and adjustment.

Machine structure

No.	Name	Description	Advantages
1	Hydraulic Part	Touch screen operation, equipment pressure provided by the hydraulic station in conjunction with hydraulic cylinders.	Precise copper sleeve positioning, wear-resistant, mold positioning throughout the process.
2	Feeding Part	Adjustable-speed motor drives the wear-resistant conveyor belt.	Extended conveying device increases material capacity, automatic and precise feeding reduces labor.
3	Pushing Part	Precision guide rail pushes the battery to accomplish pre-sealing, secondary sealing, and tertiary sealing in a step-by-step manner.	Step-by-step feeding system.
4	Molding Part	Made with high-quality imported materials, high precision and strictly manufactured; designed with 4 positioning points cooperating with the mold base slide.	4 positioning points cooperation with mold base.
5	Discharge Part	The discharging mechanism automatically unloads the battery cell into the discharge chute.	Discharge and material loading on the same side, more convenient for the operator.
6	Electrical Part	Mitsubishi Electric PLC, multiple sensor switches connected throughout the machine; automatic alarm in case of abnormal situations, automatic stop; equipped with emergency stop and door opening protection functions.	Convenient operation, safe.
