Both NC feeder and roller feeder belong to punch feeder， which is a machine for conveying materials。It is responsible for transferring the raw material needed to be processed through leveling and then to the equipment for punching and forming products in the production of punch presses.The appearance of punch feeder greatly reduces the production cost of products and saves human resources, which has a good competitiveness in the modern society with fierce competition.However, the use of punch feeder customers know that the punch feed machine will often appear biased feed inaccurate phenomenon. what is the reason?
1、Material thickness adjustment is not well adjusted, resulting in the roller press material is not tight slip, according to different material thickness, to timely make the feeding material thickness adjustment of the feeder.
2、When the material thickness is thick, the pressure spring of the roller feeder is not pressed tight in time, which leads to insufficient pressure of the roller and skidding, so the feeding is not accurate.
3、Oil stains on the brakes of the high-speed roller feeder caused the failed brakes，Or excessive brake friction, loss of friction force，the brake pads need to be re-polished or replaced。
4、There is iron debris in the gear, which leads to incorrect feeding.
5、The roller in the one-way clutch is worn out, which leads to inaccurate feeding and needs to be replaced with a new roller.
NC servo feeder inaccurate feeding problem：
1、NC servo feeding machine feeding roller pressure is insufficient, resulting in slipping and feeding is not allowed, adjust the pressure screw to increase the pressure of the roller.
2、NC feeding machine gear into the iron scrap, need to remove iron scrap and foreign matter, usually pay attention to clean maintenance.
3、Servo motor drive belt gap is too large, need to remove the cover to adjust the belt gap.
4、If the Angle of relaxation time is adjusted too late, the mold guide pin will leave the material guide hole. If the roller does not press the material, the material will retreat. Adjust the correct relaxation time.
5、The oil stain on the feeding roller caused it to slip. It is necessary to clean the oil stain and keep the roller clean.
In addition, punching machine feeding is a kind of punching machine feeding, no matter it is bias feeding machine, roller feeding machine, leveling feeding machine servo feeding machine and so on. There are many reasons for bias feeding, and we need to find out the reasons in other places.
For example：
Stamping die positioning problem: in the feeding process of the punching machine, in order to meet the requirements of the use of precision, the general requirements in the mold will be set pin, if in the feeding process, the material will run off, it is very likely that the mold positioning pin is not done well, need to do the positioning pin.
The quality of the coil itself will lead to inaccurate feeding problems: if a coil material rough edge is serious, bending, uneven or not wide or narrow snaking, easy to lead to the feeding process of the material deviation, so need to replace the standard coil.
Foreign matter in the feeding machine: there is foreign matter in the gear or the roller, which may cause the displacement and deviation of the material during the feeding or leveling. It is necessary to clean the foreign matter and the gear or roller.
