The principle of the feeder and the adjustment of the feeding step

The feeding step of the feeder, also known as the feeding length, refers to the length of the conveyor belt that the feeder feeds into the mold at a time. It is determined according to the shape and size of the stamping part and the needs of the stamping process. Different finished products often have different feeding steps, so it is very important to master the adjustment method of the feeder step in actual use. Feeders can be divided into air feeders, roller feeders, and NC feeders. Manufacturers who have compared their parameters will know that they not only have huge differences in price, but also that all kinds of feeders can achieve The maximum feeding step distance is also different. It is impossible for a set of processing machines (punching machine, shearing machine) to use only one processing technology. Usually, multiple processing technologies are used to manufacture multiple products. At this time, there will be multiple feeding steps, and the selected materials What is needed for the machine is the maximum feeding step. Only by knowing the maximum feeding step, can we truly choose a suitable and accurate feeding model to ensure that the minimum investment can meet the needs of various processing techniques. After the NC feeder step is adjusted, it needs to be actually tested to ensure that the feed distance is correct and stable. The specific test methods are as follows: 1. After the punch is turned on, stop to the bottom dead center position, and draw a line on the material , The rotary punch press to the bottom dead center, draw a line on the material, repeat the measurement several times, compare with the required step, and then adjust the step fixing screw until the required step is reached. 2. Feed the material into the mold. After the punch is inching to punch the pilot hole, move the punch to more than 3 points, and measure the position of the pilot pin and pilot hole until the pilot pin and pilot hole are aligned. Correct. 3. When detecting the step distance, do not use the single action function to stop the punch at the top dead center for measurement, because at the top dead center, the feed is only half of the feed, and the stop position is different each time, and the step distance cannot be measured. Be sure to measure after 3 o'clock. 4. If the NC feeder is equipped with a larger punch and is equipped with a second fine-tuning device, the first fine-tuning device on the eccentric disc (ie the fine-tuning of the scale ring) is approximately adjusted to the required step, and the fine-tuning is from the original rocker arm position. The second fine-tuning device is adjusted.
