Description

eleven

The invention relates to forging and pressing machinery, in particular, to designs of devices for adjusting the closed height of the press and the position of the upper ejector.

The purpose of the invention is to increase reliability.

Fig, 1 shows the device, a general view, a partial section; FIG. 2 is a section A-A in FIG. 1; FIG. 3 is a section BB in FIG. 1; in fig. 4 - node I in fig, t ,.

The device for adjusting the closed height of the press and the position of the upper ejector has 1 housings 2 mounted in a slider, each of which has a nut 3, a worm gear 5 mounted on the keys 4 and connected to a worm 6. Inside the nut 3 screwed threaded part 7 in the form of a binder, connected to the connecting rod 8. On the one side of the housing 2 in its middle part a window 9 is made. On the outer surface of the nut 3 in its middle part there is a toothed rim 10 that engages with teeth timber 11 mounted on the platen 12, articulated with a screw 13. The screw 13 in turn is mounted in the nut 14, Shar Nirni connected to beam 16. Beam 15 Ejector 15 is suspended from the rod 17 of power cylinder 18 mounted in the slide. On the latter also mounted electric motor

19 with a gear wheel (not shown) hooked to the wheel 20. A gear wheel 20 is mounted on the shaft 21 and connected through sleeves 22 and between the exact shaft 23 and the worm 6. The position 24 denotes the traverse of the press.

The device works as follows.

The inclusion of an electric motor 19

10 rotates mounted on its shaft

the gear wheel that rotates the wheel 20, the wheel 20 connected through the couplings 22 and the interlock shaft 23, in turn, drives the shafts

is a worm 6, a worm 6 rotates the wheels 5, and with it the keys 4 and the nuts 3, the nuts 3, rotate c along the thread along with the slide. The threaded part 7 - a brace with a string 20 remains in place. As a result, slider 1 either rises relative to the press table when it is necessary to increase the closed height, or descends lower to the table in order to

25 to reduce the closed height of the press. Simultaneously with this rotation of the nut 3, the gear 11 of the screw 13 is transmitted through the gear rim 10, the screw 13 is therefore also respectively

30 is screwed into the nut 14 with an increase in the closed height or unscrewed from the nut 14 with a decrease in the closed height of the press.

The use of the proposed device provides an increase na35
