AUTOMATIC MACHINE FOR THE KNURL OF NAILS, MODEL -0217AUTOMATIC MACHINE FOR THE KNURL OF NAILS, MODEL -0217

THE AUTOMATIC MACHINE FOR THE KNURL OF NAILS
is intended for drawing direct or screw corrugatedes on cylindrical surfaces of nails with the purpose of increase adhesiveness nails with connected wood.

TECHNOLOGICAL PROCESS OF MANUFACTURE:

Process of a knurl consists in the following: preforms of nails from the bin move in the mechanism of carry of preforms which by the piece gives orient preforms to a zone of a knurl. The knurl of grooves on a rod is carried out between two dies, motionless fixed in Die-headerand mobile, making a reciprocation.

NOTE:
AUTOMATIC MACHINE FOR THE KNURL OF NAILS is delivered with a package of spare quickly worn details and completed with the instrument for maximal diameter of a nail of 4 mm with which automatic machines passed production tests. The instrument on other standard sizes of a nail is delivered at additional expense.
The enterprise realizes service during all period of maintenance of an automatic machine.

In order to enhance technological capabilities of nailing machines our company has developed the following options:

1. Auger device. It is designed for transportation of nails from under the tray into the container. Thus, during transportation of nails cut-offsare separated and sent to a separate container.

This will allow:

  1. to avoid the deburringin many cases, e.g. for construction nails, which would reduce costs;
  2. cut-off separated from of the nails can be handed into scrap metal, which also would reduce costs;
  3. to escape from use of the place for container with nails, which would save production area;

2. The second lubrication circuit. This centralized lubrication is driven by a separate electric drive. It works on thethick lubricant through dosed feeders. Lubrication is triggered periodically, for example, after 1 hour and it delivers a portion of the lubrication to points.

Lubricated points:

  1. Slide rails of cut (6 points);
  2. The axis of the lever clamp - 1 point;
  3. The lever clamp roller - 1 point;
  4. Top rail of slide landing - 2 points;
  5. Telescopic connection of feed lever - 1 point.
  6. This allows: 

    1. significantly reduce fattening of nail and thus to escape thedeburringof nailstogether with a screw mechanism;
    2. to improve the lubricants reliability and reduce the time required for machine lubrication.

    3. Equipment of wire-nailing machines with frequency converters of induction motors. This allows smooth handling of productivity from minimum to maximum. Currently, nailing machines have only two speeds due to changeable pulleys. This allows to increaseproductivity of nail making machines by an average by 10% due to choice of optimum speed.
