Introduction of Lihao servo feeder.

Aug. 22, 2020

In order to achieve stamping automation, more and more manufacturers choose to use feeder to achieve automatic production, reduce personnel operation, reduce production costs, improve production efficiency.There are many types of feeder, the main commonly used in the market are air feeder, roller feeder, servo feeder, and so on.Today we will briefly introduce the servo feeder.

servo feeder

Servo feeder adopts CNC system to accurately control the feeding roller, so compared with other feeding equipment, it has the advantages of higher feeding precision, better stability, easier operation, wider application range, etc. At present, servo feeder has become the most used feeding equipment in the stamping industry.


There are three main types of NC servo feeder:

1. Pneumatic NC servo feeder

This is stamping industry the most used servo feeder machine, it USES cylinder clamping loosen, installation without limit, not only can match almost all punch to use, and can be used with hydraulic press, shearing machine, but as the cylinder push-pull form relax, there is a certain response time, therefore is not suitable for high speed feeding.

At present, the models of PNEUMATIC NC servo feeder are: NCR series, NCF series, NCH series, and the new NC series.


2. Mechanical NC servo feeder:

The relaxation way USES the mechanical lever to relax, relax the speed is fast, there are restrictions on the installation, mainly with the punch for short step high speed feeding occasions, it is more convenient to relax debugging, it is suggested that mechanical NC and pneumatic NC can be used in the occasion.

At present, LIhao mechanical NC servo feeder is mainly JNC series products.


3. Biased NC servo feeder:

This machine is specially developed for the processing and production of wafer cutting customers. It adopts the servo system imported from Japan and adopts closed-circuit computer feedback control to ensure the accuracy within ±0.02mm.To realize the material transport on the two-dimensional plane, to make the circular blanking reach circular intercutting, and to ensure the flatness of the circular, maximize the utilization of materials.


The specific selection of what feeder, but he also consider other factors, such as the properties of stamping materials, stamping process, type of punch, speed, and so on.Only by integrating the actual needs of customers can we recommend a suitable feeder.
