RU169270U1 - WIRE FEEDER - Google Patents

Abstract

The utility model relates to mechanical engineering, namely to the design of devices for unwinding wire. The technical task of the utility model is to prevent spinning of the spinner. The technical task is carried out due to the fact that the wire feed device contains a bed and a pinwheel, while the pinwheel is rigidly fixed to the rack, a hole is made in the center, inside which a rolling bearing is fixed, inside which a guide tube is fixed, inside which a wire passes through the guide roller and connecting the bay with the machine.

Description

The utility model relates to mechanical engineering, namely to the design of devices for unwinding wire.

A device for feeding wire (SU 1827305 A, 07/15/1993) [1], designed to fix the coil with the wire and its unwinding in the manufacture of springs, consisting of a base (bed), an axis, a bearing, a guide roller is known. It has a significant drawback - during the winding of the spring, the spinner rotates and spins strongly, which requires additional time and effort to stop it, because It does not have brakes, which entails non-production costs of working time.

The technical task of the utility model is to prevent spinning of the spinner.

The technical task is carried out due to the fact that the wire feed device comprises a bed, a rack rigidly mounted on it and a guide tube mounted on rolling bearings for passing the wire inside it and feeding it through the guide roller to the machine, characterized in that it contains an element for laying the bay made in the form of a mushroom, rigidly mounted on a stand, in the center of which a hole is made, while the bearing is fixed inside the specified hole, and the guide tube is fixed inside bearing.

In FIG. A device for feeding wire is shown, where it is indicated: pos. 1 - bed; pos. 2 - rack; pos. 3 - pinwheel; pos. 4 - bay; pos. 5 - emphasis; pos. 6 - a directing pipe; pos. 7 - hole; pos. 8 - rolling bearing; pos. 9 - a directing roller; pos. 10 - wire; pos. 11 - machine tool.

The wire feeder may be configured as shown in FIG. To the bed (1) (as an option, the steel plate is 5 mm), the stand (2) is rigidly fixed (as an option, two, the steel metal profile is 3 mm). A pinwheel (3) (as an option, from light alloy metal, in the shape of a mushroom), is rigidly (welded) with the inner side attached to the second end of the rack (2), the stop (5) is rigidly fixed on the outside (alternatively, two, a metal pin ), in the center of which a through hole (7) is made. Inside the bore (7), the rolling bearing (8) (two, as an option) is rigidly fixed. A guide tube (6) is movably fixed inside the rolling bearing (8) (as an option, made of steel, hollow inside, bent, 25 mm in diameter). The guide roller (9) (as an option, two) is movably fixed to the inside of the turntable (3) and to the stand (2).

A device for feeding wire works as follows: for winding spirals and springs, the coil (4) is laid on a turntable (3). The wire (10) from the bay (4) passes through the guide tube (6) and the roller (9) to the machine (11), where a spring or spiral is wound. Under the tension of the wire (10), the guide tube (6) freely rotates around the bay (4), inside the rolling bearing (8), removing coil by coil. When the winding machine (11) stops, the tension of the wire (10) weakens and the guide tube (6) stops.

The device has the greatest effect when winding springs and spirals from a wire with a diameter of 0.2-1.2 mm.

Thus, the proposed device for feeding wire has a novelty and significant differences from the prototype, provides new useful characteristics, prevents spinning of the turntable, reduces the cost of working time and increases the efficiency of the machine. It can be used in repair units of the Ministry of Defense and other law enforcement agencies.
