The air feeder is the earliest feeding equipment used in the stamping industry. Its principle is to use air as power, clamp the material by the cylinder, and feed the material by the telescopic stroke of the cylinder, and adjust the length of the feed by adjusting the cylinder. The length is controlled by adjusting the stroke of the cylinder.

Advantages: easy to operate, easy to install, affordable, and can realize automatic punching feeding equipment at the lowest price. In actual production, it is mainly used to feed stamping products that require low accuracy and low speed.

Disadvantages: easy to damage the material, and the worn O-ring will affect the feeding accuracy.

High-speed roller feeder

The roller feeder is currently the most widely used feeding equipment. Its principle is to connect to the output shaft of the punch through a connecting rod, which is driven by the punching press, and the feeder is adjusted by the deflection of the eccentric disk.

Advantages: high feeding accuracy, fast speed, no additional energy supply, and extremely low failure rate.

Disadvantages: Due to the limited deflection of the eccentric disc, the maximum feeding length can only reach 300mm, and the feeding step is inconvenient to adjust.

High-speed gear change feeder

It is an intermittent feeding method driven by a cam. The feed distance change is made by the transformation of 2~4 gears.

Advantages: the unique split cam mechanism and precision gear ensure high-precision and high-speed feeding. There is no need to adjust the feeding thickness, and the feeding distance can only be changed by gears. The relaxation device is an eccentric cam, so the relaxation angle can be adjusted freely within the range of 0°~180°.

Disadvantages: small scope of application and high price.

Servo feeder

This is a model that uses a full set of the numerical control system to drive the feeding roller to realize the feeder. The feeding parameters (length, speed, quantity) can be set on the touch screen to complete a simple feeding length, and the feeding length is unlimited.

Advantages: servo feeding precision is high, multi-stage feeding, long stepping function, convenient operation and debugging, the high degree of customization (various thick plates, swing type), especially suitable for precision machining occasions

Disadvantages: higher cost

Clip-on feeder 

Driven by a cam, using a cambered cam and 3 plate-shaped cams to achieve high-speed and stable feeding. A built-in detection mechanism can detect blockage or deformation of materials. The feeding interval angle of 165 degrees makes the material stay longer in the punch. Combined with the mold guide pin, the release time of the material can be adjusted when guiding. Can transport round or square wire. 

Advantages: The feeding speed can be synchronized with the punching machine, and the fastest speed can reach 1200 times/min. Its feeding accuracy is higher, more stable, and the machine is lighter and smaller. It is suitable for feeding ultra-thin materials, such as connection High-precision and high-speed stamping of detectors, lead frames, and inspection parts.

Disadvantages: Generally used for feeding materials with material between 0.1 and 0.5 mm, the scope of application is small and the price is relatively high.
