Abstract

The invention relates to the field of cold metal forming, in particular, to devices for feeding long material to the treatment area. The purpose of the invention is the expansion of technological capabilities by moving the material with a variable feed pitch. The material is fed by feed rollers to the treatment area, where the material presence sensor interacts with it. To adjust the feed pitch, the carriage movement is activated, which moves the material by a specified amount. Then the carriage moves to its original position and acts on the limit switch that turns off the movement drive. The control of the roller feed, the electric motor and the material availability sensor is carried out by sensors that are interoperable with a lever connected to one of the rolls. 3 il. s (lu sp ate

Description

The invention relates to the cold treatment of metals by pressure and can be used to feed a long-dimensional material into the treatment area. The purpose of the invention is to expand the technological possibilities by moving the material with a variable feed pitch.

1 shows a device for feeding a lengthy material to a treatment zone; FIG. 2 is a view of a type A in FIG. 1; fig. 3 shows the electrical circuit of the device.

The device includes a housing 1 in which the feed rolls 2 and 3 are mounted with overrunning clutches (not shown). On the lower roll 2, a lever 4 is fixed, which is a crank associated with lever 5, driven by a drive (not shown). The upper roll 3 is spring-loaded spring 6 to the roll 2 and is equipped with a lifting mechanism with a rod 7, the lever 8

t gu 9 and an electromagnet 10.

I

On the housing 1 mounted sensors 11 and 12 of the angle of rotation of the roll 2 with the ability to interact with the lever 4.

Between the housing 1 and the knives 13, located in the treatment area, are mounted the guides 14 along which the carriage 15 moves, carrying the gripping body made in the form of a clamp latch 16, spring-loaded spring 17. The carriage is equipped with a drive made in the form of a traveling micrometric screw 18 mounted on the base 19 and passing through the carriage 15, of the crown wheel 20 mounted on the screw 18 and engaging with the screw 21 connected through the coupling 22 with the electric motor 23. Between the carriage 15 and the housing 1 of the 45 drive m, and sensors installed flax limit switch 24 with the ability to interact with the carriage 13.

A material presence sensor is installed in the treatment area; it is made in the form of a hollow body 25, in the cavity of which a rod 26 is installed, spring loaded 27, contacts 28. and 29, two shoulders 30, hinged on 55 scientific research institutes and connected to electromagnet 31.

The sensor 26 is electrically connected to the electric motor 23, and the electric one;

with the ability to interact with the lever, characterized in that, in order to expand technological capabilities by moving material with a variable feed pitch, it is equipped with a material presence sensor located in the treatment area, a movement actuator of the material availability sensor, an end switch and an individual movement actuator carriages made in the form of a micrometric drive screw connected to the carriage and an electric motor connected via

11 .- with electromagnet 31 via sensor by rotor 23.

The limit switch is electrically connected to the electric motor 23, the electromagnet 10 through the sensor 12 to the electric motor 23.

The device operates as follows.

Claims (1)
