The normal feed accuracy of the servo feeder is generally about 15 threads (0.15mm) without considering the influence of external factors. If the accuracy is further improved, it is necessary to install the positioning pin in the mold to cooperate with the feeder relaxation function. When a feeding error occurs, first check whether the mold is stable. Then close the punch. When the mold is stable, manually feed the material, and then draw a line on the steel belt to measure the feeding error range.

  Servo feederWithout considering the influence of external factors, the normal feed accuracy is generally about 15 threads (0.15mm). If the accuracy is further improved, it is necessary to install the positioning pin in the mold to cooperate with the feeder relaxation function. When a feeding error occurs, first check whether the mold is stable. Then close the punch. When the mold is stable, manually feed the material, and then draw a line on the steel belt to measure the feeding error range.

There are many factors that affect the servo feeder, mainly in the following aspects:

1. Feed rate. If the automatic speed of the servo feeder is too fast, the paper feed roller will slip when the servo motor starts quickly. Or when the motor stops running instantaneously, the motor shaft vibration is unstable. Therefore, the faster the feed speed, the worse the accuracy. The slower the speed, the more stable. Solution: The smaller the automatic speed setting, the better, while keeping up with the continuous firing of the punch.

2. Feeding length. The longer the feed length, the greater the cumulative error. Correspondingly, the longer the length, the faster the feed speed, thus affecting the feed accuracy. Solution: slow down the automatic speed, by the feeder control punching.

3. Material width or thickness. The wider or thicker the material, the higher the loading rate. When the motor of the servo feeder starts instantly, it is easy to slip, or the gravity reaction of the feeding leveling frame affects the accuracy. Solution: try to choose a large torque motor or increase the width of the feeder.

4. The mold is not smooth. During the feeding process, the steel belt does not fit smoothly with the mold, resulting in burrs and sticky materials, and unilateral friction between the steel belt and the mold material. Solution: First check whether the mold is not straight. The die reference line needs to be perpendicular and parallel to the press table or feeder. Otherwise, the steel belt will run off during the feeding process. Second, check whether the mold is damaged. Check whether the strip steel is smooth in the mold.

5. The feeding material is not correct, or the compression nut is too tight and too loose. In this case, the general steel belt will run off, affecting the feeding accuracy. Solution: When the servo feeder is feeding, the steel belt needs to be parallel and perpendicular to the feeder. Press the nut or spring evenly on both sides.

The servo feeder adopts the electronic control system to control the servo motor to accurately convey the plate, which overcomes the shortcomings of the traditional feeder, such as low feeding accuracy, high feeding failure rate and complex feeding step adjustment. Is the current stamping industry cost-effective feeding equipment. In the actual stamping production, the correct installation is the fundamental to give full play to its efficient performance. After the feeder leaves the factory, professional installers will be assigned to the customer site to help the customer assemble and debug until the customer's production line can achieve high efficiency.
