A punch press feeder, as the name suggests, is a machine for conveying materials. It's used in the punch press production process to transfer the raw material, after leveling, to the punch press to form the finished product. The advent of punch press feeders has significantly reduced production costs, giving them a strong competitive edge in today's highly competitive market. However, customers who have used punch press feeders know that they often experience material deviation and inaccurate feeding. What are the reasons for this material deviation in punch press feeders?
Inaccurate feeding by the feeder:
1. Insufficient pressure on the feed rollers of the feeder causes slippage and inaccurate feeding. Adjust the pressure screw to increase the roller pressure.
2. Iron filings or foreign objects have entered the gears of the CNC feeder. The iron filings and foreign objects need to be removed. Regular cleaning and maintenance are also important.
3. The gap in the motor drive belt is too large. The cover needs to be removed and the belt gap adjusted.
4. If the relaxation time angle is adjusted too late, the mold guide pin will leave the material guide hole, and the roller will not press the material down, causing the material to move backward. Adjust the relaxation time to be correct.
5. Oil stains have entered the feeding rollers, causing them to slip. The oil stains need to be cleaned and the rollers kept clean.
In addition to the above, whether it is a sway feeder, roller feeder, leveling feeder, or servo feeder, all of these are feeding devices for punch presses. As they are all types of feeding equipment for punch presses, there are many reasons for material deviation, and we need to find the cause in other places.
For example:
Stamping die positioning problem: In order to meet the accuracy requirements during the feeding process of the punch press feeder, it is generally required to set positioning pins in the die. If the material deviates during the feeding process, it is very likely that the positioning pins of the die are not properly made and need to be remade.
Quality issues with the roll material itself can lead to inaccurate feeding: if a roll material has severe burrs, is curved, uneven, or has inconsistent widths and forms a serpentine shape, it is easy for the material to deviate during the feeding process, so it is necessary to replace it with a roll material that meets the standards.
Foreign objects inside the feeder: Foreign objects inside the gears or rollers can cause the material to shift or deviate during feeding or leveling. It is necessary to remove the foreign objects and clean the gears or rollers.
What are the reasons for material deviation in a punch press feeder? The above is an analysis of abnormalities such as material deviation and inaccurate feeding in a punch press feeder. If customers encounter the same problem during production, they can refer to the above for solutions.
