hand staple tools. The purpose of the invention is the expansion of technological capabilities. The stapling head includes a housing 1, a mechanism with indentation of the staples, an anvil 4, which is made in the form of a cylindrical rod mounted through the housing with a through central hole and screw-Q ports for its lower part, a bend 6 that has grooves for forming the bracket and flats, the dimple 13, which is placed inside the anvil and provided with rigidly fixed fingers 14 and 15, which interact with the grooves to form the bend, two actuators, one of which is rigidly connected with the bend, and the other the second - with the striker. The brace head forms a bracket from a wire blank and presses it into the stitched parts. 6 Il.

The invention relates to devices for fastening predominantly elements of wooden structures, such as containers, and can be used in the woodworking industry for equipping production assembly lines, as well as for producing hand-held stapling tools.

The purpose of the invention is the expansion of technological capabilities.

Figure 1 shows a staple tin, cut, in a position that precedes the formation of a staple; FIG. 2 is a view A of FIG. 1; on fig.Z - that on. Fig. 1 is in a position after forming the staple; Fig. 4 is the same after pressing in the bracket; figure 5 - view B on yig.1; figure 6 - section bb In figure 2.

The brace head comprises a housing 1 in which a radial-thrust bearing 2 is placed, which is fixed by a ring 3 and serves for placing an anvil 4 in the housing 1, which is fixed by a ring 5 and has the form of a cylindrical rod with a through central hole, the lower part of which is cut through by screw grooves. The anvil covers the bend 6, -. in which grooves 7 are formed to form a bracket and a groove 8 (Fig. 6,2), which limits the bend 6 from turning as a result of interaction with a finger 9 placed on the housing 1. In the bend, the inlet holes 10 and slots 11 are made, for guiding the wire during its feeding and during the formation of the shackle, as well as on the flats 12. In the hole of the anvil 4 there is inserted a firing pin 13 with a gesture fixed with fingers 14 and 15 at its ends, interacting with

screw grooves of the anvil 4 and grooves 7 zagibatel 6. Finger 14 has

recess for jumper bracket.

As the drive for the reciprocating movement, the bend 6 is applied, for example, an air cylinder 16, which is provided with a return spring.

17, and as the reciprocating drive of the striker 13, for example, pneumatic cylinder 18 is used.

The stabbing head is working downwards

The compressed air is supplied to the piston cavity of the pneumatic cylinder 16. The bend 6 moves up and the return spring 17 compresses. At the same time, compressed air is supplied to

the rod cavity of the pneumatic cylinder 18. The die 13, connected with the screw grooves of the anvil 4 with fingers 14 and 15, rises, rotating the anvil 4. In the position when the bend 6 and bob

The nuts 13 are set to their highest position, and a wire blank (not shown) is fed into the tapered holes 10.

When connecting the piston cavity

pneumatic cylinder 16 to the atmosphere compressed air leaves it. The return spring 17 moves the bend 6 down. The formation of the staples resting on the anvil 4 (Fig. 3) occurs. In

formation time

held in the extreme upper position by the force of the pneumatic cylinder. 18, which ensures the immobility of the anvil 4. After the formation of the rod bracket of the pneumatic cylinder 18 is completed, it is connected to the atmosphere, and compressed air is fed into the piston cavity of this pneumatic cylinder. the piston rod of the pneumatic cylinder 18 moving

The striker 13 is progressively downward, which presses the bracket into the fastened elements (figure 4). Anvil 4, rotating J provides direction for both the impressed bracket and the striker 13, then the cycle repeats.
