A4215: DOUBLE-STROKE SINGLE-IMPRESSION DIE WIRE NAIL MACHIN composed of cast iron bed frame on which all units and mechanisms are fixed: combined drive
(microdrive for adjusting operations and force drive); shafts; feed device; clamping and heading mechanisms; burr
removing mechanism; cutting and sharpening mechanism; pneumatic clutch.
A4216: The unit is a high-speed automatic machine. The nail head production cycle consists of 2 stages:
1. Preliminary heading.
2. Final heading.
This is the peculiarity of the machine design.

DOUBLE-STROKE SINGLE-IMPRESSION DIE WIRE NAIL MACHIN A4215:
- Quality wire straightening is provided as the straightening is performed in two relatively perpendicular planes.
- Ready adjustment due to use of the microdrive.
- The adjustment is simple and can be done only with one branch of wire.

DOUBLE-STROKE SINGLE-IMPRESSION DIE WIRE NAIL MACHIN A4216:
- Original design of the die unit protected by copyright allows to make broad nail heads due to vertical movement of
the die unit;
- The use of hard-carbide tools (knives, clamping dies, heading punch) allows for long-term operation without
readjustment;
- Small installation area with no special substructures required;
- Maintenance safety, since all moving parts are enclosed in casings.

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.

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.
