. I The invention relates to the processing of metals by pressure, namely, radial forging machines. Radial forging machines are known, having strikers mounted on a frame, equipped with reciprocating drives, isolated in the form of a crank valor, connected by means of intermediate mechanisms to drive shafts; ....:. A disadvantage of the known machines is the low reliability of operation with an increase in their speed. The purpose of the invention is to increase the reliability of work. , For this, each intermediate mechanism is made in the form of a link, rigidly connected with the corresponding crank shaft, as well as by means of the rocker stone with an eccentric mounted on the corresponding drive shaft. -. FIG. 1 schematically depicts radial forging. machine figure 2 section aa on. 1J in FIG. 3 — section BB in FIG. 2. The radial forging machine contained strippers -1, rigidly connected with the cool dogs themselves 2. The wings 2 move in guides made in the base 3 of the machine. The scenes 2 cover rocker reed 4, in which the crank shafts 5 are mounted, making an oscillatory motion. The crank shafts 5 are rigidly connected to the wings 6. The drive shafts 7, rotating in rolling bearings. mounted 7 in the frame of the machine 3, with one end of the kinematically connected with the crank shafts 5 by means of intermediate mechanisms consisting of the wings 6 and the rocker stones 8 placed in them, the drive shafts 7 with other ends are rigidly connected with gears 9, which, in turn are associated with parasitic gears 10 of a gear transmission mechanism. The latter is simultaneously a device synchronizing the work of all the strikers. A gear transmission is kinematically coupled to an electric drive. in the frame of the machine 3 Rotary boxes 11 are installed, in which the thrust bearings 12 of the crank shafts 5 are located eccentrically to the axis of their rotation. The machine works as follows,. The rotation from the electric drive is transmitted to the gear transmission mechanism and, therefore, through Gears 9 and 10 to the drive shafts 7, on which eccentric rotational stones 8 are mounted, which drive the crank shafts 5 into the oscillating motion through the wings 6. Crank shafts 5 are oscillatingly driven into reciprocating movement of the link 2, and, consequently, the working bodies are 6ofiv.H 1, which deform the workpiece. In order to change the distance between the dies 1 in the process of deforming the blanks using a separate actuator (not shown), the boxes 11 are turned. Application of the inventions will improve the reliability of the machine.
