SU10281A1 - Bar Iron Hook Making Machine - Google Patents

Description

The present invention relates to machine tools for making hooks from bar material with an eccentrically mounted finger on a rotary disk, and in this machine two rotary rollers with eccentrically mounted disks and fingers are moved inside which rollers protruding from the ends of the disks are moved. A bar advanced between the fingers and the ends of the inner rollers is twisted around the ends of the rollers around the protruding ends of the rollers. The bend of the back of the hook is due to the rotation of the lever with a slot for the rod. The movement of the rollers and the pivoting lever is transmitted from the slide with reciprocating motion, at which the rollers are turned by engaging the gear racks with the gears, and the lever is rotated to bend the back part by pressing a special hammer on it.

In FIG. 1 shows a side view of the machine; FIG. 2 is a top view.

The machine consists of two rollers 2 with eccentrically mounted on the ends of their disks 5, in which

the fingers are secured 13. Inside the rollers 2 there are rollers 14 protruding beyond the disk 5. The rollers 2 rotate under the influence of the lowering slide 25, turning with the help of racks 4, rollers 1 and linked with them, through gears 3 and 24, rollers 2. In the slider 25 also strengthens the knife 8, for cutting off a bar of material of a certain length of a piece and shock 7 for turning the lever 5, which serves to bend the back of the workpiece. The machine works as follows: by moving the carriage 16 through the system of levers 10, 11 and 12, the material rod advances for a certain length between the fingers 13 and the ends of the rollers 14 protruding from the discs 5, then lowering the slider 25 the rod is cut off by the knife 8 and further lowering the slider 25 of the rail 4 turn the rollers 1, as well as the rollers 2 coupled to them, so that the fingers 13 bend around the ends of the bar around the ends of the rollers 14. With further lowering of the slider 25, the drummer 7 presses lever b, which, turning around finger 15, zvivaet bend the back of the hook and the latter takes

the shape shown in FIG. 1 dotted line. When the slider 25 is raised, the dog 9 reinforced in it, with an inclined plane, moves the cross back to 20, tying the rollers 14 and pulls them out of the opposite hook, which, by the reverse movement of the rollers 14, under the influence of springs 21, pushes the hook out of the lever 6 and then the operations are repeated in the same order.

The subject of the patent.

A bar iron hook making machine using a finger eccentrically mounted on the rotary disk, characterized by the use of two swiveling, using toothed rails 4 and gears 24 and 3, rollers 2 (Fig. 2) with eccentrically mounted disks on them with fingers 13 bending the ends of the bar material skipped between them and the protruding ends of the 14 rollers, and a lever b located between the rollers to bend the rear part of the workpiece actuated by the hammer 7 (Fig. 1) fixed to the crawl a carrier carrying rail 4, and, for cutting the workpiece before bending, the knife 8.
