The invention relates to the processing of metals by pressure, namely design-forging equipment.

Known Foundation frame vertical screw forging machines [1] contains the Foundation pit, which placed the bed in shock absorbers and guide systems.

The famous design of the forging hammer with vibroisolating the striker plate [2]

In this design to prevent horzontally movement of the striker plate has a system of roller guides with mobile devices.

The disadvantages of the known designs are the large size and complexity of the system elements vibroisolating hammer of small size and simplified isolation system of the striker plate.

The problem is solved due to the fact that in the known construction of the forging hammer with vibroisolating the striker plate, comprising a frame, a striker plate, base frame, vibration system, between the support frame and Foundation, and the guides, the guides are made in the form of form a sliding pair of outer and inner plates installed around the perimeter of the striker plate with the formation of the installation gap between the outer plates and the side edges of the bed.

Installation gap filled malosimeynyy loose material. The inner lining is rigidly connected with the side edges of the striker plate and the outer plates fixed height limiters.

Exterior trim is supplied over the entire height of the slots, which opened with a gap on the depth of the metal insert, and the vertical end faces of the outer plates height in the zone of their contact with each other are staples.

The actual pads are made from a material with a low coefficient of friction and low friction, such as PTFE.

In Fig. 1 schematically depicts a forging hammer with vibroisolating the striker plate in section; Fig. 2 section 1 1 on the frame of the hammer with the striker plate of Fig. 3 site And the junction of separate alimentazione in podkapotnoj pit 5 Foundation 6. Between the side faces of the striker plate 2 and the side walls of the frame 7 of the forging hammer 1 set 8 external and 9 internal lining. Internal linings 9 are rigidly connected to side faces of the striker plate 2 and the outer plates 8 fixed height limiters 10. The gap between the outer plates 8 and the side walls of the frame 7 is filled loose malosimeynyy material 11. The size of the granules of the granular material 11 is chosen from the condition that the individual granules did not Wake up in the gap between the outer plates 8 and limiters 10 and, at the same time, to separate the granules of the granular material 11 could at packing to move freely in the gap between the outer plates 8 and the side walls of the frame 7.

Between the outer pads 8 are connected using metal inserts 12, instituted in vertical grooves 13 arranged over the entire height of the outer plates 8. The metal insert 12 is wound into the grooves 13 of the outer plates 8 with a gap depth, and vertical ends themselves of the outer plates 8 height (outer side) in the area of their contact with each other have bevels 14.

Plates 8, 9 are made of a material with a low coefficient of friction and low friction, such as PTFE.

< / what the striker plate the last 2 commits vertical vibrations together with the supporting frame 3. Under eccentric shock occurs the moment. Install cover plates 8,9 on the lateral faces of the striker plate 2 in the form of two sliding pairs, pressed to each other due to the fact that the gap between the side stitches the frame of the hammer 7 and the outer plates 8 filled loose malosimeynyy material 11, prevents horizontal movement of the striker plate.

The design of the plates 8,9 and their preload bulk material, which fills the gap between the outer plates and the sides of the frame in the system of the forging hammer with vibroisolating the striker plate has a small width (which helped to place it between the side faces of the striker plate 2 and the side walls of the frame 7), a large area of contact on the sliding surface (hence to reduce the contact stress) and ease of Assembly inaccuracies in the gaps with opposite sides between the side faces of the striker plate 2 and the side walls of the frame 7 is easily compensated by the necessary number Malozemov granular material 11).

Malosimeynyy material 11 under the action of vibration fills all gaps between the outer plates 8 and the side walls of the frame 7 and provides a uniform transfer of horizontal loads at netparty allows to increase service life and easier maintenance the construction as a whole.
