Advantages and disadvantages of several common punch feeders
- Dec 13, 2018 -

In the process of feeding the feeder, in addition to selecting a good feeder manufacturer, the selection of the feeder type is particularly important. There are many types of feeders, mainly air feeders, high-speed roller feeders, NC servo feeders, high-speed gear replacement feeders and clip feeders. Many manufacturers often only talk about their advantages when introducing various types of feeders, not to mention their principles and shortcomings, which brings a lot of trouble to customers when they actually purchase. As a professional feeder manufacturer。

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

Air feeder advantages: easy to operate, easy to install, affordable, and can achieve automatic stamping feeding equipment at the lowest price. In actual production, it is mainly used for feeding of stamping products with low precision and fast speed.

Disadvantages of air feeder: easy to damage materials, O-ring wear has an impact on the feeding accuracy.

2. High-speed roller feeder: The roller feeder is the most widely used feeding device at present. The principle is to connect the output shaft of the punching rod through the connecting rod, and the punching press drives the operation. The feeder is adjusted by adjusting the yaw amplitude of the eccentric disk. Feed length.

Advantages of high-speed roller feeder: high feeding accuracy, high speed, no additional energy supply, and extremely low failure rate.

Disadvantages of high-speed roller feeder: Due to the limited eccentricity of the eccentric disk, the maximum feeding length can only reach 300mm, and the feeding step adjustment is inconvenient. The punching machine needs the output shaft to be installed.

3. The principle of the NC feeder is that the servo motor and the PLC control system drive the timing belt to drive the upper and lower rollers to rotate and press loose to achieve quantitative feeding.

Advantages of NC feeder: Double control mode of button and touch screen, easy operation, servo control, higher feeding precision, multi-stage feeding, convenient feeding length, maximum feeding length up to 9999.99MM, wide and feeding step Long distance stamping industry.

Disadvantages of NC feeder: Pneumatic NC maximum speed is 200 beats / min, mechanical NC maximum feed speed is 250 beats / min, and the price is slightly higher.

4. The high-speed gear replacement feeder is an intermittent feeding method driven by a cam. The change of the feed distance is changed from 2 to 4 gears.

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

Disadvantages of high-speed gear replacement feeder: small application range and high price.

5, the clip feeder is driven by a cam, using a curved cam and three plate cam design, to achieve high-speed and smooth feeding. Built-in inspection mechanism to detect blockage or deformation of materials. The 165 degree feed section angle allows the material to stay longer in the press. Combined with the mold guiding pin, the release time of the material during guiding can be adjusted. It can transport round or square wires.

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

Disadvantages of the clip feeder: generally used for material feeding in 0.1~0.5mm, the scope of application is small, and the price is relatively high
