Adjustment of various parts of NC roller feeder
- Dec 03, 2018 -

The rapid exhibition of the stamping industry has made the number of NC roller feeders more and more. Since the stamping products are sometimes not updated, the nature of the stamping raw materials, the length of the feeding, the thickness of the materials and the height of the stamping die are different. When replacing the stamping product, the punching machine NC feeding machine should be adjusted accordingly to punch out the ideal product. Below, Long Gengyi introduces the adjustment method of several parts of the NC roller feeder:

First, the adjustment of the feeding height of the NC roller feeder

When replacing the stamping die, the height of the lower die of each product may be different. At this time, the NC roller feeder should be adjusted according to the height of the die lower die. The adjustment plate behind each NC roller feeder will have some adjustments. The amount can be adjusted. Firstly, the outer hexagon M12 screw that fixes the NC roller feeder to the fixing plate with the external hexagon M12 or M14 is loosened. Note that it is not too loose, and then the lifting screw nut on the bottom of the mounting plate is loosened. According to the height of the lower mold, adjust to the same height. If the NC roller feeder is to be lowered, rotate the bottom screw of the mounting plate counterclockwise. If the NC roller feeder is to be raised, turn the screw at the bottom of the mounting plate clockwise. When the NC roller feeder adjusts the corresponding position, the screw between the NC roller feeder and the mounting plate should be locked again, and then the bottom nut of the mounting plate can be locked.

Second, the adjustment of the pressure of the NC roller feeder

In the raw materials of stamping products, the materials are different and the thickness of the materials is not the same. It is necessary to adjust the intake air volume of the cylinders of the whole press. If the pressure is too high during the adjustment, the material may be too much pressure, which may cause the pressure to be relaxed. The roller is strongly impacted and deformed. If the pressure is too low, the roller cannot be pressed and the material slips, resulting in an unacceptable feeding. Only when the cylinder pressure on the feed roller is properly adjusted, the material is adjusted so that the material does not deform and the roller does not slip.

Third, the NC roller feeder shifting wheel width adjustment

If the stamping product is replaced and the raw material is widened or narrowed, the width between the retaining rollers should be properly adjusted to match the width of the retaining wheel with the material by first rotating the retaining wheel M12 screw to allow the stamping material to be in the NC. After the feeder and the stamping die are at 90 degrees, adjust the stopper wheel to the appropriate width position, and then lock the stopper wheel M12 screw.

Fourth, NC roller feeder belt installation and adjustment

After long-term use of the NC roller feeder, the motor belt may become loose or worn and need to be replaced. If the belt is loose, it should be adjusted in time. Firstly, the screw of the fixed motor is rotated and relaxed, and then the motor is moved to the belt to be tight. At the end of the position, lock the motor screws. If the belt is too tight, it will shorten the life of the belt. If the belt needs to be worn out, first loosen the bolt of the fixed motor to shorten the distance of the pulley, then take out the belt, replace it with a new one, adjust the appropriate tightness, and then lock the motor screw.

Five or three point combination, air pressure adjustment and moisture removal

After the Long Geng 楷 NC roller feeder is used for a long time, the three-point combination needs to adjust the air pressure and the water in the three-point combination by rotating the knob on the pressure regulator to adjust the air pressure required to feed the pressure roller. To remove moisture, press the button below the collection bucket to drain.
