SU423611A1 - DEVICE FOR CUTTING TUBE '* ^ "' About: • - Google Patents

Description

The invention can be used in the installation of pipelines for cutting pipes, cutting through shaped grooves, windows, stripping and stripping.

A pipe cutting device is known, consisting of a sliding carriage and a valuable clamping mechanism, equipped with carriages carrying support rollers, and a cutting head connected to the carriage by means of a sharpen joint, which ensures that it is positioned.

However, these devices do not have the versatility necessary for cutting through the shaped grooves and windows in pipes. The proposed device differs from that known in that the carriages carrying the support rollers are rotatable. This ensures upivesalnost device.

FIG. 1 shows the proposed pipe cutting device, general view; in fig.

2 is a section along the line A-A in FIG. one; in fig. 3 is a view along arrow B in FIG. one; in fig. 4 shows an embodiment of a carriage with two pairs of rollers.

The cutting head 1 is mounted on a slider 2 moving along the frame guides.

3 under the action of the screw 4, and secured with a clamp 5, one end of which is mounted on the axis of rotation 6, and the other has the ability to move in a curvilinear pair

zu a The frame 3 with the help of axis 7 is hingedly connected with one of the parts 8 of the extendable trolley and secured to it with a bolt 9 inserted into a curved groove b. Parts 8 and 10 of the extendable trolley are interconnected by rods 11 and screw 12, having left threads on one end and right threads on the other.

The cart has trolleys 13, with which it rolls around.

around the pipe 14. The support rollers are located on the axles in the carriages 15 with the shanks 16, which are fastened in the required position by nuts 17. The sliding carriage is fixed to the pipe

with the help of a chain clamping mechanism 18, equipped with carriages 19, supporting rollers 20 are unsuppleable. The carriages 19 are turning relative to the crackers 21 associated with the value of the clamping mechanism 18. Rusks

21 have handles 22 and strips 23, serving to secure the carriages 19 in the required position with a number of stops 24.

For the operation, the sections of the trolley are mounted on the tube 14 by the support rollers 13 and rolls with the nominal value of the valuable clamped mechanism 18 with the carriages 19 carrying the support rollers 20. After turning on the cutting head and feeding the tool before cutting into the pipe wall, the device is continuously rolled around the tube. After the pipe sections, a chamfering operation can also be carried out using the rolling method. To do this, turn the cutting head to the required angle from the point of the specified articulation.

To perform the slitting operation, rotate the cutting head 1 and the carriages, 15 and 19, which carry the onboard rollers 13 and 20, to the appropriate angle.

The shaped cut is made by moving the device in the desired pattern.

Subject invention

A device for cutting pipes, wave-like in the form of an extendable trolley and a chain clamping mechanism, equipped with carriages carrying onorny rollers, and a cutting head, combined with a trolley by means of scharpir articulation, which installs it in the required position, characterized in that, in order to ensure the universality of the device , carriages bearing oiori rollers are pivotally mounted.
