SU56826A1 - Cleaver for the preparation of gas generator chocks - Google Patents

Description

Known jibs, equipped with a reciprocating wide cutting knife and a group of cross-cutting knives last, have the disadvantage that the chopped chocks are wedged between them, causing frequent accidents during the subsequent working stroke of the knives.

In the proposed drill, in order to prevent jamming of chocks and self-guiding of the cutting edges when splitting along the fibers of the workpiece, cutting the knives are made in the form of pivot levers located symmetrically on both sides of the fixed knife and spring-loaded at the non-working ends.

In the proposed two embodiments of the cleaver, for preparing the gas generator choke, according to the first embodiment, the cleaver is made vertical, and according to the second, horizontal, with the resetter fingers mounted on the cleaver base located between the cutting blades.

In FIG. 1 is a side view of a cleaver for a gas generator chopper, made upright;

FIG. 2 - front view; FIG. 3 - front view of the splinter box; FIG. 4 - vertical section of the knife box; FIG. 5 is a horizontal section of it; FIG. 6 is a side view of a splitting ax made in horizontal form with a partial section along the line AB of FIG. eight; FIG. 7 is a front view thereof; FIG. 8 is a top view with a partial cut along the VG line of FIG. 6

A cleaver is mounted on a frame / mounted on a skid x or on another type of vehicle. The frame is equipped with a conveyor 3 (Fig. 1 and 2), designed to supply blanks in the form of round pieces of wood under the knife box for splitting them into gas-generator chocks. This conveyor is made of a series of endless lamellar chains extending in the grooves of the splitting frame, and the chain links are provided with pliers for better gripping of the wood to be chopped, and to hold them more firmly on the conveyor at the moment of splitting, the spring pressure plate 8, Powered by

a conveyor from the main drive shaft 4 through a pair of bevel gears, an eccentric 6, a connecting rod 7 and a ratchet mechanism 9 on the shaft of the drive wheel. The main drive shaft is mounted on racks above the conveyor and with the help of the eccentric 10 (Fig. 2) informs the return movement of the knife box located in the guides 18 (Fig. 5) in the front posts of the bed. Simultaneous transmission from the main drive shaft of movements of the knife box and the feeding conveyor ensures synchronism of the work of both mechanisms; the conveyor begins to move when the eccentric with the connecting rod of the connecting rod is between the lower and upper dead points and moves upwards and, conversely, the conveyor stands when the knife box moves downwards.

The knife head (Figs. 3, 4 and 5) encloses a system of knives: a wide cutting 11, which serves as the back wall of the knife box, and groups transverse to the cutting dissecting knives / 2, 18, 15, 16. The cutting blade 11, In order to reduce the force when splitting wood, there are several lower cutting blades. The latter are made in the form of pivotal levers on a separate axis x 17 in a knife box (slide), symmetrically located on both sides of the fixed knife 14 and spring-loaded at the non-working ends. Such a device is aimed at eliminating jamming of chocks between cutting blades and self-guiding the cutting edges when splitting along the fibers of the workpiece.

In the blocking device made horizontal (Figs. 6-8), the solid-molded frame 21 is also mounted on runner x or on another kind of wagon.

The tubular shaft 22 is rigidly fixed in the frame nest, inside which

there is a rod 25 driven by an eccentric switch 26 by means of a handle 27.

An eccentric 28 resting freely on the support ball bearing 29 is loosely attached to the shaft 22. The eccentric 28 drives the connecting rod 81, which is connected with a pin 82 to a knife frame 88, including the same knife system as in the vertical splinter shaft. Between the dissecting knives are placed the fingers 89 of the resetter.

The feeding of the splitting blanks is done through a feed hopper, which has a rigid outer wall 41 constituting part of the overall frame casting and reinforced with rib X2 for rigidity. The second wall 48 of the bunker is movably mounted on the hinge 44 and supported by the spring 45. In the rigid wall 41 of the bunker, stop stops 46 are screwed.

The cleaver is set in motion by the working pin, which is inserted into the working position by friction.

The subject matter of the invention.
