Description

Known automatic machine for winding cniipajieii and double cone furniture springs using roller feed, leveling apparatus, the mechanism for curling the wire stepper device and chipping knives.

The described IIMCCT machine, higher productivity n is more versatile.

The machine is made multi-tool, and the wire mechanism is equipped with a movable yoke, adjusting the change of the ornament and the shape of the spring.

Mechanisms of adjustment are made stationary, according to the change of niara, both in the form of an angular movement of a suspension with a roller, and in diameter and shape of a spring in the form of a cage moving in a vertical plane.

Fia FIG. 1 shows a general view of an automatic machine; in fig. 2 is a section but AA in FIG. one; in fig. 3 is a section through BB in FIG. 2; pas figs. 4 is a section along the explosive in FIG. 2

Roller leveling devices 2 are installed on the metal frame. 2. The wire coming from the bay is propelled by rotating rollers 3 two pairs on a string of mashpny, and some of these rollers are driven, and others are primed. To prevent buckling, they serve;) az1:, emny directions 4 and 5.

Continuously moving wire ;; coiled into a coil due to a freely rotating roller 6, which can be set in the desired position by means of the yoke 7 to obtain the corresponding helix diameter.

The obtaining of a given pitch of the spiral (spring) is provided by a clamping device 8, which is guided by moving the suspension 9 with the roller 10 around the axis //.

No. 116489-

The resulting helix is post-paired into the figured direction oa1; the th stand 12, which is supported through the channel on the frame of the automatic machine.

To cut the helix (spring) of the desired length, the drive rollers 3 are stopped for a short time and the engine 13 drives the upper blades 14, which by means of the rocker arm 15 are lowered and cut the helix in succession, interacting with the lower blades J6. The position of the upper blades 14 is adjusted by screws 17.

After occupying the rocker 15 of the initial non-operating position, the drive motor of the rollers 3 is automatically activated through electric restraints and the process is repeated.

The described machine can simultaneously equip five coils, the number of coils produced can be changed upwards or downwards by increasing or decreasing the number of coiling devices.

Claims (2)

1. An automatic machine for winding spirals and double-cone furniture springs using a roller feed, a straightening device, a wire curling mechanism, a stepper device and chipping knives, and so on, in order to increase productivity and giving the machine greater versatility, the machine is made multi-threaded, and the mechanism for waving a sabzhei wire with the movement of the holder, which regulates the change of the ornament and the shape of the spring. 2. The machine tool according to claim 1, characterized in that, in order to simplify its adjustment to other dimensions and the shape of the spring without changing parts of the machine, the adjustment mechanisms are made stationary, by changing the pitch - in the form of an angular movement of the suspension with a roller, and the diameter and shape of the spring in the form of a moving 3 vertical plane of the clip. ligi 4: SL J; gI, ijp- ej dita, - jfrs .. - l Cut across ya 13Si
