Description

The invention relates to mechanical engineering technology and can be used in devices for preparing pipe ends for welding.

The aim of the invention is to increase labor productivity by installing a worm on the drive shaft with fixed cleaning elements and axially re-aligned axially, fixing the cutter 3RY1 head on the end face of the screw and making the mechanism of YUKA1a and axial feeding in the form of a hook in the case, if possible; displacement sleeves with conical internal surface crackers mounted in the sleeve with the ability to interact with the conical surface and move in the radial direction, and two diametrically opposed on the casing of the worm wheels with crank fingers connected kinematically with the worm and through the crank fingers and inserted into device t gi - with a sleeve ..,

FIG. 1 shows schematically the device, a general view; 2 a top view; in fig. 3 - section A-A in FIG. one; in fig. 4 is a section BB in FIG. 2; in fig. 5 is a sectional view BB in FIG. one.

The device includes a housing 1 (Fig. 1 2), connected to the sleeve 2, inside of which the 3 clamping mechanism and axial feed for plunging is performed. In case 1, there is a rotating head with cutters 4 with cutters and a stripping unit 5, filled in the end part of the screw 6, conjugated with two crank wheels 7 in the case (FIG. 4), which are connected with fingers 8 and t gi 9 with clamping bushing 10 mechanism 3 clamping and feeding.

one

The mechanism 3 of the mode and the workpiece feed is made in the form of three (fig. 1) spring loaded 11 and ring 12 against the stop 13 of the crackers 14 placed in the grooves 15, the sides are formed by guides 16, ring 12 and clamping sleeve 10, the outer surface of which is matched with the sleeve 2, on the end of which the stop 13 is screwed, and the latter is connected with the screw 17 to the housing 1. The wiper 5 (Fig. 2) is made in the form of two double-shouldered tails 18 with the wiper elements 19,

bordering 20 counterweights 21, which are spring-loaded springs .22. On the housing 1. (Fig. 2) fixed on the switch 23, which borrows from the protruding element of one of the t g 9, provides switching off of the electric drive 24 and VAA 25 devices.

The device works as follows.

The blank 26 is inserted into the opening of the abutment 13 up to the stops 20, the stripping unit 5 and the start button is pressed until the limit switch 23 is triggered.

At the same time, the shaft 25 of the electric drive 24 together with the screw 6, the cutting head 4 with the cutters, two double-shouldered arms 18, the stripping elements 19 of the stripping unit 5 rotate counter-clockwise (Fig. 1 and 3), rotating the worm-wheel cranks 7, which through the fingers 8 transmit the rotational movement of tam 9, convert it into reciprocating.

T Gui 9 (Fig. 1 shows the moment of gripping the billet) moves the clamping sleeve 10 relative to the sleeve 2, and the crumbs 14 pressed by the spring 11 and the ring 12 to the stop 13 remain stationary in axial direction, but at the same time slide their conical surfaces along the tapered surfaces of the ring 12, the stop 13, the clamping sleeve 10 and move radially to the center to meet the surface of the workpiece 26, clamp the latter and, seizing it, begin to move together Q by the clamping sleeve 10, ring 12, spring 11 to the cutting head 4, equipped butts m and shaped cutters.

At the same time, the two shoulders levers 18 of the stripping unit 5 under the action of centrifugal force, overcoming the force of the springs 22, initially clean the surface of the workpiece with cleaning elements 19, and the stops 20, moving away from the axis of rotation of the cutting head, pass the workpiece 26 to the cutters of the cutting head 4.

After the initial cleaning of the surface of the workpiece and chamfering, the workpiece 26 begins to move in the opposite direction together with the clamping mechanism 3 and feed for cutting with the help of cable 9, crank wheels 7, and its surface is cleaned again until the limit switch 23 trips. 14, abutting against the stop 13, pressing the spring 11, sliding along the tapered surfaces of the clamping sleeve 10, the stop 13, the rings 12, move radially from the center, freeing the treated collar 26.

The work is finished and the device is ready to recycle.
