SU776700A2 - Apparatus for calibrating and straightening pipelines - Google Patents

Description

The invention relates to the processing of metals by pressure, can be used for straightening and calibrating curved pipelines and is an improvement on the known device.

From the main invention of auth. St. No. 389862, a device for calibration and straightening of pipelines is known, which contains a deforming element in the form of a removable ball connected to a cable: enclosed in a flexible casing and equipped with a driving vibratory mechanism 1. The calibration of the pipeline takes place in a reciprocating oscillatory motion. reported by a ball vibration mechanism.

- - - The disadvantage of the device is the frequent wedging of the ball tip in the calibrated pipeline, which reduces labor productivity.

The purpose of the invention is to increase productivity.

For this purpose, the gaar is made detachable in 25 forms of a tsaigi with a conical hole and is provided with a tapered striker in a hole and connected with a TipocoiM.

The drawing shows the proposed device, the cut.30

The device contains a calibrating ball in the form of: a collet 1, a guide bushing 2, a striker 5. The striker 5 is connected via a sheath 4 to a flexible cable 5. A compression spring 7 is placed between the flange of the Bushing 2 and the striker 3. Ball collet 1 is connected with a vibration mechanism 8 through the flexible cable 5 with a flexible sheath 9.

The device works as follows. A calibrating collet / with flexible cable 5 and a protective sheath 9 is inserted into the calibrated pipeline 10 up to the stop of the ball collet 1 into the deflated portion of the pipeline 10. B, the vibration mechanism 8 is switched on.

During the reciprocating movement of the flexible cable 5, the spring 7 is periodically compressed. At 1WD, the springs of the spring 7 are stripped 3, with its cannon part, strikes the conical part of the ball collet 1.

To prevent the inner wall of the pipeline 10 from being touched by a screw, sleeve 2 / has a flange // whose diameter is somewhat less than the minimum internal diameter of the pipeline.

The proposed device allows an increase in productivity by 30%. 3i
