How to do the feeder misfeed detection device
- Dec 04, 2018 -

Nowadays, with the continuous development of the society, a powerful machine emerges in the mechanical equipment, that is, the feeder. For the advantages and characteristics of the feeder, I think everyone will see and understand it in the previous article. The feeder is very suitable for the current social development requirements, and there are many advantages. Then the problem comes at this time. Have you ever understood the maintenance problem of the feeder? Everyone knows that the feeder has been used for a long time and naturally there will be problems, then everyone Want to know if the feeder misfeeds the detector? Next, let’s listen to the Xiaobian one by one:

Nowadays more and more stamping owners have chosen to use the feeder, the feeder is matched with the punch progressive die type for continuous processing and production. This processing method not only improves the stamping production efficiency, but also significantly improves the quality of the finished product. Improve material utilization and reduce production costs. However, in the actual use process of the punch feeder production line, the material feeding is often not in place due to some internal or external factors, and the feeding speed of the feeder is very fast. It is often difficult to detect in real time when the feeding is not accurate, which not only makes the quality of the finished product and The processing technology is difficult to guarantee, the scrap rate is high, and the mold is damaged, which increases the maintenance and use cost.

        So how do you solve the problems mentioned above? The answer is simply to solve the problem with the feeder feeding the wrong detection device. The feeder misfeed detection device consists of two parts: the detection host and the photoelectric part. The photoelectric part is assembled on both sides of the die inlet port of the punching die, and the cam signal of the punching machine is used as the trigger signal, which is controlled by the PLC program to reach the feeding machine at the feeding level. When feeding the mold, it can detect various kinds of insufficient feed detection or pass the detection purpose in real time, so as to effectively ensure the safety of the mold and ensure the stamping production process and product quality are guaranteed.

1. Insufficient feeding detection

Insufficient feeding detection and feeding distance detection are mainly used to match the feeding time and angle of the punching machine to detect whether the feeding of the feeder is correct and automatically control the punching process. Insufficient feeding detection is to carry out feeding once after the first step of the progressive die. The feeding distance is certain. This distance is determined by the punch feeder. It is important when the feeding is in place. The feeding of the feeder is not enough, which will lead to the progressive die. The stamped product has been scrapped or the mold has been damaged.

2. by checking out

Through detection, it is mainly used in the production process of product blanking, and the detection of blown products is eliminated to prevent the phenomenon of stacking. The product is detected by discharging once after the completion of one stamping of the progressive die. The discharging is to blow out the product by using a compressed air blowing device in a certain cam cycle, and the product passes through the light curtain to cut off the light curtain signal. During this process, the product (or scrap) must pass through the light curtain. If it is not left in the progressive die through the light curtain, the progressive die will cause damage to the mold or product during the next press.
