Description

one

The invention relates to rolling production, in particular, to the production of pipes and their processing in steam pipelines.

Production lines for processing pipes are known, which include pipe processing machines, means for centering pipes from 1 the spindles of these machines, roll tables for longitudinal and walking conveyors for ion pipes.

The purpose of the invention is to increase productivity by combining the time for transporting and centering the pipe relative to the machine spindle.

For this, the proposed line is provided with guides arranged between the rods of the walking transnorter, on which movable carriages are mounted. Moreover, a means for centering the tube is mounted in each carriage.

In addition, the carriages are connected by a rigid rod.

On fng. 1 shows a flow line, common to FIG. 2 shows a section along AA of FIG. one; pas figs. 3 is a sectional view of FIG. one.

The proposed line contains pipe processing machines / located on both sides of the line; roller conveyors for longitudinal pipe feed; inlet 2, outlet 5 and intermediate 4, walking conveyor 5 for the transfer of tubes; carriages 6 mounted on guides 7 for inserting the pipes through the machine spindle to the cutting tool; ejector 5 and stop 9. The walking transiorter 5 is molded as

a multi-link mechanism with a single drive link 10, which is an eccentric rocker mechanism, whose shaft / 2 is connected to the electronically controlled conveyor 13.

Such a design of the drive link provides the maximum possible speeds of moving the links carrying the pipes in the horizontal plane and minimal speeds in the extreme positions of the pipe laying positions, which creates unaccented operation of both the conveyor mechanisms and eliminates the possibility of pipe failure and transport.

To the drive link 10 of the conveyor 5, by means of the beam 14, the beams / 5 are connected at a defined distance from each other, and with beam 14 are the main carrier link of the multi-link. Drive link 10, beams 14 and 15 and non-drive link 16,

hinged and connected by a tie, make up a narallogram frame mechanism, with the help of which beams 15 make a plane-parallel movement.

On each beam 15 there are mounted V-shaped lifts 7S, located from the inter va; uma, providing free movement of the carriages 6. Carriages 6 with visually inserted means 19 for aligning the pipe axis with the axis of the installation of 7 and 23 sections whose sections are located in the intervals between the beams 15 of the walking conveyor 5 and laid out against each machine. The carriages 6, connected by a rigid rod 20 and mounted on the rollers 21, are moved along the guides 7 by means of an actuator 22. The rollers are located on each carriage 6 so that when moving, one pair of rollers 21 of each carriage always rests on the frame 7, while the other pair can be above the gap between the section of the plurality of guides 7. To hold the pipe on the carriages 6 while it is being fed into the stack 1 to the cutting tool, a clip 23 is provided, mounted on the pipe 20. The pipe processing line works as follows ohm After completion of processing the next pipe, all elements of the production line occupy the initial positions. The beams 15 of the walking conveyor are in the lower initial position, ensuring the unrestricted movement of the carriages 6 in the guide 7, the carriages with the treated pipe in the extreme position opposite to the machine, the clips 23 do not hold the pipe. Uior 9 is omitted and ensures that the machined pipe is not moved to the roller table 3. The pipe, previously removed by the spreader from the roller table 2, is in the original position before the stop 24. The pipes in the next section of the production line include bar 13 and Y-shaped beams pickups 18 of the walking conveyor 5 are moved to the pipe lying in front of the stop 24. With further movement of the beams 15 of the walking conveyor, the next pipe and at the same time the other pipes lying on all positions of the production line are removed under wools and 18 perekladyvayuts one step conveyor. In this case, each pipe is laid in a new position of the flow line.

4 Then, the sliding conveyor 5, moving further, is left in the lower initial position, ensuring the unrestricted movement of the carriages 6. The carriages with the pipe after its gripping by the clamp 23 move to the machine / by means of the actuator 22, providing the end of the pipe to the cutting tool. The alignment of all pipes and the clipping of the position of the end of each pipe in a strictly defined place in a flock / of a cutting tool (cutter, etc.) is performed by roller tables 2 4, as well as by stops 25 and 26, which, depending on the type of treatment, can be stationary. and moving. Moving carriages with a pipe at the first and second machines occurs simultaneously. After the carriage movement is completed, the pipe is expanded and the ends of them are processed, respectively, in each machine. Then, in the reverse order, the operations of extracting the pipes from the machines and their further shifting by means of the conveyor belt 5 are performed. The treated pipe is fed to the roller table 3. In case roller table 3 doesn’t remove the pipe, the stop 9 will be raised for a short delay. Products and tools 1.
