(54) DEVICE FOR MEASURING CUTTING OF LONG-DIMENSIVE MATERIAL

one

The invention relates to the processing of materials by pressure, in particular, to equipment for measuring cutting assembly wires and other lengthy material, and can be used in electrical, radio, and other industries.

A device for dimensional cutting of lengthy material is known, which comprises upper and lower rollers mounted on a frame and kinematically connected to each other during the technological process, the coiler carrier, length mechanization and cutting with the photosensitive element ij

However, the device has a low accuracy of cutting pieces.

The closest to the proposed technical entity is a device for measuring cutting of lengthy material, the contents are mounted on a frame and kinematically connected between each other during the technological process, the bay holder, the upper and lower rollers of the feed mechanism, the length measuring and cutting mechanism of the workpiece, consisting of on a guide carriage having an illuminator and a photosensitive element, and a drive cutting knife 22.

1 A disadvantage of the known device is the low precision of the segments.

The purpose of the invention is to improve the accuracy of the segments.

This goal is achieved by the fact that the device containing mounted on the bed and kinematically

10 co-holder, upper and lower rollers of the feed mechanism, the mechanism for measuring the length and cutting of the workpiece, consisting of

15 placed on a guide carriage, having an illuminator and a photosensitive element, and a power cutter blade, equipped with an electromagnet and a mechanism for disconnecting the feed mechanism, made in the form of a lever with a bearing, kinematically connecting the upper feed roller with a power cutter blade, which has recesses for bearings lever and attached to the electromagnet, electrically connected with the photosensitive element of the measure the length of the workpiece, while the guide carriage consists of a rotary plate and sve30 toprozrachnoy dimensional range having the bottom of a channel corresponding to the diameter of the elongated material to be cut.

FIG. 1 shows a diagram of the device in FIG. 2 - section A-A in FIG.

The device contains a frame on which a feed mechanism is placed, consisting of an eJ motor 1, driving the lower drive roller J and the upper pressure roller 4 through the gearbox 2, the cutting mechanism, the joint; the electromagnet 5, on the stem of which the cutting knife 6 is rigidly fixed, the bay holder 7 with the drive 8 and the measuring mechanism of the length of the cut blanks, consisting of a measuring line 9 fixed on the frame of the device, the movable carriage 10 and the bar 11 covering the measuring channel measuring line 9, supporting wire 8 in this channel.

The measuring line 9 is made of a translucent material, such as Plexiglas, and, to increase rigidity, it is reinforced with a metal rail 12 with pressure, through which the carriage tO is cut manually by 3 times the given length of the cut piece. „

On the carriage 10, on the one side of the measuring line 9, at the level of the channel directions K for the passage of the wire, is placed the source 14 of the light, and on the other side the photosensitive element 15 electrically connected with the electromagnet 5.

The cutting knife b moves along the guide rollers 13 and has two recesses 16 for bearings 17, the axes of which are connected by a lever 18 with a pressure roller 4 and a strap 11 which rotates on axes fixed at both its ends.

The device works as follows.

The wire 8 to be cut into dimensional workpieces from the coil holder 7 is fed by the lower driving roller 3 through the hole in the cutting knife used in the measuring line ruler covered by the bottom 11 of the channel. The size of the channel is selected according to the wire diameter in such a way that it ensures free passage allows for curvature due to excessively large channel size. The carriage 10 is set in such a way that the distance from the cutting knife 6 to the light beam passing from the source 14, the light to the photosensitive element 15, corresponds to a predetermined length of the wire blank. Upon reaching the end of the wire 8 of the light beam, the photosensitive element 15 commands the electromagnet 5, which drives the cutting knife 6.

At the beginning of the movement of the cutting knife b due to the curvature of the grooves 16, the bearings 17 through the lever system raise the upper pressure roller 4 and

rotate bar 11. When the upper pressure roller 4 is lifted from the lower leading roller 3, wire feed 8 is stopped, bar 11 releases the cut piece, which, from, the channel of the measuring line 9 falls into the receiving device. At the end of the cycle {aa electromagnet 5 with a cutting knife 6 returns to its original position, - the strip 11 covers the channel under the wire

Q in the measuring ruler 9, the upper pressure roller 4 presses the wire to the lower driving role. 3, the wire is again fed to the mechanism for measuring the length of the workpiece.

The transition from one size of the cut piece to another is performed visually by dividing the rail 12 of the measuring line 9 by manually moving the movable carriage 10 with the photosensitive element 15.

0 In addition, the device performs dimensional cutting of installation wires, PVC tubes and other similar materials up to 500-BOOmm in length and expands the range of application of automatic cutting under the stringent requirements on the length of the cut pieces.
