Automatic manufacturing process

This high-speed line is designed for automatic laminating of motor cores, and other structure parts need skewed, rotating and automatic stacking rivets.

When the strip material comes out of the coil material by a double decoiler, it will be straightened by a leveling machine with S-loop rack. Then it will be feed by a coil feeder and enters into the progressive dies.

The motor core/ rotor stator punching can be completed continuously: Punching--Forming --Finishing--Trimming--Automatic lamination--Blanking with skewed laminations--Blanking with rotary laminations or other blanking processes. The entire process is automatic.

High-efficiency and high-precision

This line can feed the metal coil in the speed of 60m per minute, and the stamping is generally in the range of 200 to 600 times/min, which ensures s a high efficiency of production.

The coil feeder that used in this line is mechanical cam feeder, which is reliable with a meager failure rate and very high precision feeding performance.

Main Parts & Description

1. Double Uncoiler

It used to uncoil the metal strip from coil material, and the twin head type will improve the efficiency of changing the coil.

Operation: Non-Motorized (Motorized for optional)
Mandrel Expansion: Manually (Hydraulic for optional)
Coil Width: 20mm-100/200/300/400 mm
Coil Thickness: 0.1-1.6mm
Coil I.D.: 450-530 mm, Coil O.D.: 1200 mm
Loading Capacity: 0-500/1000/2000/3000 kgs

2. S-loop Straightener

The S-loop straightener is specially designed to level the metal strip for high-speed motor core lamination stamping. S-loop rack can storage the material to ensure high-speed feeding, and it equips photoelectric sensor for loop control.

Coil Width: 20mm-100/200/300/400 mm
Coil Thickness: 0.1-1.2 mm
Feeding Speed: 0-60 m/min
Straightener Roller: 5 pcs on top + 6 pcs on bottom
Pinch Roller: 2 pcs
Roller Adjustment: 4 points fine micro-adjustment

3. CAM Feeder/Gear Feeder

Cam feeder is a mechanical feeder that feeds the metal strip into the high-speed press and progressive die, with high-speed 500spm and high feeding accuracy +/-0.01mm.

Coil Width: 100/200/300/400 mm
Coil Thickness: 0.1 - 1.6 mm
Feeding Length: 11.5 - 245 mm
Feeding Speed: 500 SPM
Feeding Angle: 180
Release Angle: Adjustable

4. High-Speed Stamping Press

HE high-speed press machine body is made by high intensive cast iron, through natural environment eliminates stress to enhance machine durability. It performances high accuracy in automatic feed, single stroke, or progressive die applications. A forced lubrication system ensures the operation reliability. And the electric control system achieves a high automation operation and operation safety.
