Description

The invention relates to a crushing machine tool, using a two-blade slide, receiving reciprocating movements along the axis of the circular axle from the crank mechanism, using drive rollers to rotate the latter. In the proposed machine, the axes of the rollers designed to rotate the rounds are located in the fork-shaped supporting parts, and jog angular movements are obtained from the main shaft of the machine, and the supporting parts of the rollers for receiving new rounds and dropping the treated ones periodically receive a turn around their respective points axis.

In FIG. 1 shows a cross-section of the machine; FIG. 2 - longitudinal section of the machine; FIG. 3 is a perspective view of a part of the fixture for rotating the fork bearings; FIG. 4 is a perspective view of a mechanism for communicating jogging movements to a circle; FIG. 5 is a perspective view of the plow and the mechanism for bringing it to j motion; FIG. 6 is a longitudinal section of the plow; FIG. plow front. .

The rounds to be processed on the proposed stack are laid on the table 7 (Figs. 1, 2), from which they are taken

are given to the rollers 5. The rollers 5 are placed with their axles of fork-shaped support parts 18 rotatably fixed on the axis 19. The parts 18 are connected, with the machine bed, the spring 10 is provided with a sector 75, with a cable 9, passed through a hole in the lever 2, reinforced on the machine bed, and equipped with a stop 75, which acts as a lever on the cable 9. The rollers 5, mounted on parts 18, receive, in order to rotate the machined round wheel located on them, a periodic rotary motion, for which .5 chained pulleys gear 26 with each other and the toothed wheels 76 placed on the axle 19 parts 18 (FIGS. 1,4). The gear Iff carries a shoulder 16 loaded with a spring and connected by a cable 24 with a lever 76 interacting with a fist 77 mounted on the axis of the main shaft .27 of the machine (Fig. 1, 2, 4).

The shaft 27 of the machine (Fig. 2) carries a wheel 7 provided with a handle 28 and connected by connecting rods 29 with pins 4 of the plow 30, Plow 30 (Fig. 5-7) is equipped with two working in opposite directions knives and consists of two parts 6 and moved relative to each other by a screw 31 Part 6 the plow carries trunnions 4 and part 8

32 rolls of ovoid shape, with the help of which the plow rests on the machined round k. The ply 30 is also equipped with a sled 33, which, when it moves, moves along rails 34 connected at the ends with sliders 20. The sliders 20 can move in vertical parallel x 3 (figs. 1, 5) when turning the lever 2 connected with sliders 20 tons gami 2.

Before starting work, several rounds are placed on the table 7 of the machine (Figs. 1, 2) and by turning the lever 2, the sliders 20 and 1, the guides 34 of the slide 33, together with the plane 30, rise to the upper position (dotted line in Fig. 1). Then one of the rounds collides with the table 7 on the rollers 5, after which by turning the lever 2 backward the plow 30 is lowered onto the round bar to be ground. the wheels 7 of the reciprocating movements and the knives of the plow 30 make the rounding barging. Simultaneously with the rotation of the wheel 7, the fist 77 rotates, which through the lever 76, the cable 24 and the arm 75 (Figs. 2, 4) acts on the gear 76, as a result of which the rollers 5 are periodically rotated and the angular jog movements are transmitted to the round to enable consistent debarking his: around the contour. At the end of the debarking, the round frame 2 turns again, and on one side the pitch 30 rises above the round circle, and on the other side the lever 2, acting on the stop 75 of the cable P, moves the latter, as a result of which the sector 75 rotates around the 7P axis. and together with it the supporting parts 75 of the rollers 5. At the same time, the barked round rolls from the rollers 5 to the receiver of the finished products.

Further, pressing the arm 35 (Fig. 1, 3) moves the parts 22 and 23 of the lever 2, but the thrust 75 of the cable 9 is freed from the influence of the lever 2 and the supporting parts J8 together with the rollers 5 under the action of the spring 7 (9 returns) initial position. When approaching the initial position of the part J8, it is hit in the bracket 77 connected with the bar 72 of the table 7, as a result of which the bracket 77 rotates this bar near the axis 25 and the new round to, lying on the bar 72, is thrown and

rolls down into the shed of part 78. After that, by turning the lever 2, the plow 30 is lowered onto a new round to and the process described above is repeated.

The rollers 5 designed to support and rotate the rounds can be made up of separate parts disposed of; adjacent rollers in staggered order to provide space for chip removal (Fig. 2).
