Automatic Hydraulic Crimping/18650 Sealing Machine for Cylindrical Battery Cases



1. Equipment Description

1.1 Working Principle

The hydraulic cylinder, driven by the hydraulic station power transmission device, enables intermittent motion. Using a copper-bushed guide seat in combination with high-precision high-frequency guide rods, the machine generates substantial pressure to press the battery case and cap to the process-required dimensions, achieving the sealing purpose.

 

1.2 Performance Features

The entire machine integrates electrical and mechanical systems, with production fully automated under PLC control. It offers low energy consumption, low cost, high efficiency, high precision, easy maintenance, and low failure rate.

 

2. Main Technical Specifications

Airtac cylinders

Mitsubishi electrical control system

Touch screen fine adjustment control on upper frame

ChuanZhun sensors

MEAN WELL power supply

Equipped with safety protection device

Protective guard for upper pressing plate opening/closing

Sealing: First, second, and third sealing molds, made of wear-resistant oil steel material

 

3. Main Components

A. Hydraulic Section

Hydraulic-driven precision cylinder generates large sealing pressure.

Positioning guide pillars move vertically with high performance.

Eight copper bushings for accurate positioning and wear resistance.

Mold positioning throughout the process, low noise.

Touch screen manual fine-tuning, HMI smart control, easy settings.

 

B. Feeding Section

Extra-long conveyor increases loading capacity, reduces operator workload.

Transmission uses German NEY bearings.

Taiwan TWT adjustable-speed motor drives wear-resistant feeding belt, ensuring accurate and safe material feed.

 

C. Pushing Section

Intelligent sensors detect battery position and transmit signals quickly.

Dual-axis positioning with single-cylinder U-shaped pusher block to pre-press battery caps.

Pre-sealing mold integrates capping function; pre-sealing, second, and third sealing completed in one cycle.

 

D. Molding Section

Airtac cylinder drives bidirectional mold base for cyclic sealing, completing the third seal.

Mold base is made from oil steel, heat-treated for wear resistance, corrosion resistance, and high-temperature resistance.

Optical fiber positioning prevents misaligned pressing; auto alarm if position is incorrect.

Sealing molds undergo special vacuum treatment and are made from imported high-quality materials.

Mold lifespan exceeds 600,000 cycles under normal operation.

The third sealing mold features a usage counter (manual reset only).

 

E. Hydraulic Station

Equipped with 5 MPa hydraulic station and 80 mm diameter hydraulic cylinder for sealing pressure.

 

F. Discharging Section

Automatic unloading mechanism transfers finished cells to discharge chute.

Loading and unloading on the same side for single-operator operation, reducing labor costs.

 

G. Electrical System

Manual mode for mold adjustment/testing before switching to automatic operation.

Mitsubishi PLC program monitors the entire process.

Multiple sensors, safety light curtains, automatic alarms, and emergency stop function.
