SU45264A1 - A machine for making foals used in the molding of radiators - Google Patents

Description

. In the proposed machine, for preparing foals, used in forming radiators consisting of a series of consecutively arranged in accordance with the operations performed by mechanisms for wire feeding, bending, cutting, etc., controlled by a common drive, a device for arching the ring part of a colt. This device uses a cylindrical protrusion, ,, „, consolidated on one of the cutting, scissors blades and serving to bring the cut - s KOHUa wire into the recess of the stationary 1Whide and rotating neck & .

In FIG. 1 depicts a common; -:,; type of machine with a partial cut; FIG. 2-side view of the machine with a partial cut; FIG. 3 — a device for braking wire movement; FIG. 4- scissors device.

which device is located, the braking movement of the wire at the time of cutting off. This device consists of a spring clamping plate 4 (Fig. 2 and 3), which is affected by the end of the lever 5, forcibly lowered by the action of the cam 6 wedged on the shaft 2, and which presses the wire to the pad 7. Then the wire passes through the feed rollers 8, 9, of which the top has a groove around the circumference and the bottom protrusion on the part of the circle corresponding to the length of the wire fed to make a separate foal. These rollers 8, 9 receive rotation from shaft 2 by means of bevel / (and cylindrical 77 gears. Then the wire passes through the hollow head 72, carrying Circuit J3, which gets rotated by means of gear, F4 from the main shaft 2. Scissors 75, 75 are installed next to this roller, one of the cutting blades of which is provided with a cylindrical protrusion 77. When shears are pulled down, the cylindrical protrusion 77 produces the input of the cut end of the wire into the pro- re cutting of the fixed sleeve J8 Noah in the hollow roll 72, carrying u stubble J3, equipped with side | finger when turning is produced conductive wire vygi- banie (Figures 1 and 2.).

To communicate the movement of the cutting links scissors are eccentrics 19,

-20, affecting the blades levers

scissors 75, J6, and for pressing the wire to the lower blade when cutting, a spring 2 / is attached to the upper blade, and to guide the foal to the scissors serves a guide frame 22 attached to the cylindrical protrusion / 7

top blade of scissors 15, 16.

The subject matter of the invention. 1. A machine for the manufacture of foals Used in the molding of radiators consisting of a series of successively distributed in accordance with the operations performed by mechanisms for feeding, bending, cutting, etc., controlled from a common drive, characterized in that the cylindrical the protrusion / 7, fixed on one and 1 of the cutting blades of the scissors / 5, 16 serving, when the latter were mixed, for inserting the cut end of the wire into the slot of the stationary sleeve 18, which has a rotating brush 13 with a bending finger.

2. In the machine tool according to claim 1, the application for feeding wire rollers 8, 9, of which one has a groove and the other protrusion on the part of the circle corresponding to the length of the wire fed.

3. In the machine tool according to claim 1, use a clamp plate 4, which serves to retard the movement of the wire at the time of bending and cutting the product (Fig. 2 and 3).

4. In the machine tool according to claim 1, use a spring 2 / attached to the upper cutting blade of the scissors and designed during cutting to clamp the wire to the lower blade (Fig. 4).
