Description

The proposed mechanical hammer for hot metal working is driven by a motor or other drive. In order to increase the impact, the head of the proposed hammer moves down not only from the effect of its own weight, but also from the additional force applied to it in this direction by means of a cable tied up with a rotating drum. The other end of the same cable under the action of the second-upper rotating drum raises the woman, so that the proposed hammer can be considered to some extent a double action hammer, and since the rotation from the drive to one or the other drum is connected by means of a friction clutch, the hammer can be called friction. The expert sees the advantage of the hammer offered by him in that the woman in him has the job of being easier than other equivalent hammers, and therefore less energy is required to lift it.

In FIG. 1 depicts the type of the proposed hammer from the side; FIG. 2- front view; FIG. 3-section of its upper part along the nuamt AB in FIG. 2 and FIG. 4 is a horizontal section along the line of the LED in FIG. 2.

, Two beds / hammers are installed / 1eny on the main length and are fastened at the top by slab 2. In guides (//, privin 219). :.

to the beds, goes up and down Baba JO. A shaft 3 is mounted on the upper plate 2 in bearings, rotated by means of gears 4 and a flexible gear from motor 25. Shaft S and conical gear J2 are freely seated on shaft 3, and between them are movably mounted on the shaft on long keys the friction clutch 7. A cable is wrapped two or three times through the drum S, one end 9 of which is attached to the bogie JO by the spring buffer 28, and the other end 9 goes to the drum 79 seated on the shaft 7 and seizes it two or three times Attached also to the female 70 by means of a lever system 20-2 T, Val / 7 and drum 19 are transmitted from gear 12 through gear 13, shaft 14 and a pair of bevel gears / 5.

The friction clutch 7, when swapped over the shaft 5, can act either on the drum 8, pressing it with the left one in FIG. 2 side, or gear 12 right side. To reposition the coupling there is a fork 5 (Figs. 2 and 3), which is represented by one arm of a cranked lever 26, the other arm of which is connected by a lever 27 to lever 6 for operation by hand. In order to be able to rearrange this lever with his foot, he is bound to 25 with a 24-K pedal with a lever b (or pedal).

Then tipHkpeplenny XK bottom of the end P of the pipe I will be wound on this drum (with I speed, which must be greater than the speed of free fall of the woman) and; its tension will increase the speed of the descending woman, and, consequently, the force of her strike. The upper drum S, being disconnected during the lowering of the female from the coupling 7 and rotating freely on the shaft 5, will not prevent such a movement of the cable. -

The subject matter of the invention.

A friction mill, characterized by the use of a cable drum 79, equipped to create a forced movement of a hammer hammer; With an endless rope, P, 9, connected to the hammerhead woman, which, in its fall, receives under the influence of the rope, during the activation of the drum J9, an additional force in the direction of its fall.
