The invention relates to mechanical engineering, in particular to the design of press-forging equipment.

The purpose of the invention is to increase reliability and durability.

Figure 1 shows the hammer, a general view; Fig. 2 shows a guide assembly, a general view; on fig.Z - section aa in figure 2; figure 4 - section bb in figure 2; figure 5 - section bb In fig.Z.

The assembly contains 2 timber 3 installed in rack 1 of the bed, clamp bolts 4 passed through the holes of timber 3 and racks 1, gaskets 5 mounted in rail 3, mounted in rack 1 hydraulic cylinders 6 with plungers 7 with spherical ends, pneumohydroaccumulators 8, connected The corresponding cavities of the hydraulic cylinders 6, as well as elastic elements 9. In the beam 3, from the side of the stand 1, nests 10 are made coaxially with the said holes, in which elastic elements 9 are placed between the stand 1 and the ends of the sockets 10. The gaskets 5 are made of more material other than the material of the timber 3. The fixed bolts have split sleeves 11 with adjustable nuts and 12 lock nuts 13. In the timber 3 there is a hammer 14 for the hammer.

The node works as follows.

The gap a (fig. 3) between the bar 3 and the base 14 of the stamping hammer is set using the adjusting nuts 12 and the split sleeves 11. After screwing in or unscrewing the adjusting nuts 12 and obtaining the clearance required by condition

m of work, the last stopper of the vehicle with lock nuts 13. Then, from the pneumohydroaccumulators 8, pressure is applied in the cavity G of the hydraulic cylinders 6. Plungers 7 abut against gaskets 5 and take the load when applying out-of-center strikes by a woman 14 on the workpiece.

The technical and economic effect of the implementation of the invention is provided in comparison with the basic object due to the increased reliability and durability.

Claims (2)

1. The knot of the female guides of the punching hammer, containing the cant installed in the rack of the bed, as well as the tightening bolts passed through the openings of the beam and the stand, characterized in that, in order to increase the reliability and durability, it is fitted with gaskets installed in hydraulic cylinders with plungers with spherical ends placed with the possibility of interaction with gaskets, pneumohydroaccumulators connected to the corresponding cavities of hydraulic cylinders, as well as elastic elements, in ce from the rack coaxial with said apertures formed socket, the elastic elements placed in between the last stand and the ends nests. 2. The node according to claim 1, from l and h yushchi and the fact that the elastic elements are made in the form of cup springs. eleven FIG. five
