The invention relates to a device for sorting out damaged pipes on a pipe drawing bench for multiple consecutive pulls of the ones passing through the bank in a closed circuit Pipes with an inclined drainage grate arranged below the drawing level for forwarding of the tubes before and after the drawing processes into a storage container and with one the tubes from the Pick-up device for a lifting device that brings the loading table.

The object of the invention is to provide facilities on a draw bench of the known training described to be provided to remove surface damaged or crooked pipes without stopping the draw bench to be able to sort out with the least amount of effort.

This is achieved according to the invention in that in the end region adjacent to the storage container of the drain grate with rollers that can be driven in both directions of rotation, their upper edges are above the grate surface, provided and lowerable below the surface of the drain grate Roller table is arranged and that the area of the drain grate lying under the drawing axis as a an axis extending in the pulling direction is designed to be rotatable grate section.

This training bench has the advantage that

a) no hall crane is required,

b) crooked pipes are transported to a straightening system and back without interrupting the cycle,

c) the surface-damaged pipes are sorted out,

d) the removal of the finished pipes, the bent pipes and the damaged pipes as well as the The drawn goods are delivered on one and the same transport route and

e) the width of the system changes despite the various design requirements results in relatively small dimensions.

In the drawing, a draw bench according to the invention is shown in FIG

F i g. 1 in plan view and in

F i g. 2 in a sectional view in the direction of the line XX in FIG. 1 shown.

From the top view according to FIG. 1 shows the front drum bench 1, the draw bench 2 with its drive 3, the loading table 4, the pivoting roller table 5, the roller table 6, the loading table 7, the chain lifter 8 with transfer arm 9 and drive 10 and the adjustment bar 19.

On the other hand, FIG. 2 serves to explain the continuous process in the case of multiple consecutive operations Pulling pipes.

The pipe to be processed comes, for example, from a store one behind the other over the roller tables 6 and 5, where it rolls over inclined grids 11 to a collecting space 12, which is located under the support table 7 and is limited by rails 15 downwards by rails 15, when the roller table 5 is swiveled down it comes to rest in front of the chain lifter 8. An adjustable slide 13 has the task of changing the passage according to the pipe dimension. After the collecting space 12 has been filled, the chain lifter 8 starts moving intermittently, the pocket depth of the chain lifter 8 being limited beforehand by an adjustable bar 19 at the opening of the collecting space 12 according to the pipe dimension, so that only one pipe is received in each pocket. that is now up to the height of the support table 7, where it is inevitably brought to the support table by means of transfer arms 9, which with the chain hub 8, since mounted on the same upper axis of rotation, executes the same intermittent movement. A lifter 14 on the side wall of the loading table 4 brings the tube over a slope of the loading table 4 into the vertical drawing plane, in such a way that the tube can be pushed in a known manner over the stopper of the stopper rod in the loading drum.

By turning the drum by 180 °, the pipe reaches the drawn position, where it is pulled from its tang Pulling carriage is detected and pulled through the die.

After the end of the train, the pipe falls vertically down onto the drainage grate, which consists of fixed grate bars 11 and pivotable grate bars 16.

The pivotable grate bars 16 are brought out by means of hydraulic cylinders 17, so that the falling Pipe is first diverted to the right, where a test for surface damage or Degree of straightness is investigated. If the pipe is flawless, it is guided by the grate bars that have been moved back 16 over the fixed grate bars 11 to the left, where previously over hydraulic cylinders 18 the roller table 5 has been pivoted so that the pipe rolls to the seeding space 12 without hindrance.

If, however, a fault has been found on the pipe, the roller table 5 remains in its working position and the pipe in question is driven by the driven one Rolls either brought to a straightener or to an exclusion trough. Is the pipe if it has only been straightened, it will be reversed on the same roller table after the straightening process the direction of rotation brought back where it is then released by pivoting the roller table 5 to the collecting space 12.

Once the tubes have reached their final dimensions, the roller table 5 and the pivotable tube bars remain 16 in AbtraöBportlage so that the tube opens Can be fed to the entire roller conveyor to a warehouse.

Takes into account more meters by verfügliche overhead cranes This means no waiting, even düreh exchange of Aüähebefs 14 against Mehrfachhubaggregat is suitable for multi-pulling machines. It is essential that the condition of the tube can be observed and that the workshop integrity is no longer damaged in any way. Corresponding controls ensure a continuous workflow without additional workers.
