Device for introducing plugs into a plug rolling mill

The invention relates to a billet mill for reducing the wall thickness a heated seamless steel tube to the desired caliber. In particular, the invention relates to a device for feeding the Billet to the free end of the water-cooled mandrel between the rolling mill rolls of the billet rolling mill when rolling the seamless Tube and for removing the billet from the mandrel after the seamless tube is rolled and before it is stripped.

409807/0460

In the manufacture of seamless steel tubes, a tube blank is used in a rotary tilting furnace that heats the blank to a rolling temperature of about 1288 C, so that the blank can then be pierced. The heated tube blank is then suitable Way to a Mannesmann rotary billet or mandrel rolling mill line, where the heated billet is inserted into a piercer will. Here it is gripped by two inclined rollers that move the billet forward in a helical and horizontal direction. When passing through the rollers, the transverse rolling action forms a hollow and centrally arranged billet, which forms the inner surface of the thus elongated seamless tube. Each piercer is driven by a 4,000 horsepower motor. That on the first rolling mill The upcoming seamless tube is relatively thick-walled, which is why it is passed through a second mandrel mill in a suitable manner. In this, the pipe is lengthened and the wall thickness is reduced while the inside diameter is increased at the same time. From the Mannesmann mandrel rolling mill the heated seamless tube becomes a stick or Mandrel rolling mill, where the wall thickness is roughly on the final Passage size is reduced and the pipe largely reaches its final length in its passage through the rolling mill. In the stick or Mandrel mill, the hot seamless tube is passed along a predetermined transport path through a pair of grooved mill rolls, which are arranged on both sides of the transport path and have a gap between them, which is part of the predetermined transport path forms. The one upstream of the mill rolls Part of the predetermined transport path consists primarily of a guide channel and an inlet guide member that directly is arranged rolls in the vicinity of the gap between the rolling mill. The billet mill also has stripping rollers,

409807/0460

the downstream with respect to the rolling mill rolls on both sides of the predetermined Transport path are arranged and have a gap between them, which forms part of the transport path. Downstream of the stripping rollers, at one end of the transport path, a water-cooled mandrel is attached which extends lengthways of the predetermined transport path extends through the space between the stripping rollers and at its free end one has releasable billets or plugs therefrom. This is in the space arranged between the rolling mill rolls. In operation, a billet of the desired size is placed in the space between the mill rolls and arranged in connection with the free end of the piercer. A ram is then operated, which extends along the Guide trough moved, whereupon the rolling mill rolls moved to form the gap in their operating rolling position and at high speed to be turned around. The ram pushes one end of the hot pipe lying in the guide trough against the guide inlet in the gap between the mill rolls, whereby the drill is gripped in the grooves of the mill rolls and over the at the end of the dome provided plug is pulled through the gap. When the grooved rollers the heated seamless drilling Pull through the gap, is or, the ram is withdrawn. After the rolling process of the rolling mill rolls has ended, the plug is removed from the end of the mandrel and inserted into a Ktihlwasserbad spent, with the rolling mill rollers moved into their rest position and brought the stripping rollers into their working position will. The seamless pipe is then returned along the predetermined transport path via the stripping rollers to the guide trough. It has been shown in practice that the grooves of the rolling mill rolls should be elliptically shaped in order to avoid that the pipe is cut will. That results from a single pass through such

409807/0460

Seamless tube resulting from rolling mill rolls is somewhat elliptical in shape and the entire roll is not of uniform wall thickness on. Therefore, in order to achieve a uniform wall thickness and training in the pipe, it is necessary to use the seamless pipe by means of liftable, To rotate the rollers arranged in transverse gaps along the guide trough by 90 and then through the plug mill again to direct. The stripping rollers are therefore moved into their rest position and the rolling mill rollers are brought into their operating position, whereupon a plug is attached to the end of the piercer and the entire process is repeated. It has been shown that a substantial reduction of the seamless tube during its second pass through the plug mill can then be achieved, when the second plug is slightly larger than the first plug.

So far, the feeding and removing of the stopper was in the space between the mill rolls and to the end of the piercer, i.e. the stopper clamping, carried out manually, the one for the The worker responsible for the plug places the plug in the rolling groove against the piercer rod, depending on the size of the plug with a hand chain or with hand pliers. When the hot seamless tube has moved through the mill rolls, removed the same worker made the stopper, making it rolled, heated, seamless Tube can be stripped from the piercer rod, whereupon the same process is repeated for the next rolling pass. However, it is the manual handling of the stopper is laborious, slow, dangerous for the workers involved, dirty and hot. So is the manual The plug is particularly expensive to handle because of the labor costs involved, slow because of the time taken by the worker is required to remove and re-insert the plugs,

409807/0460

and dirty and hot due to the fact that the worker is is located in the vicinity of the heated tube during its passage along the predetermined transport path. The great closeness of the worker to the pipe during its passage through the predetermined transport route and a possible malfunction of the stripping rollers make the manual handling of the plug dangerous, in particular because a malfunction of the stripping rollers causes the tube to move at high speed just then moved along the predetermined transport path when the worker manually removes a plug from the end of the piercer.

It is already a device for the automatic feeding of stoppers has been proposed to the end of the piercer in the space between the rolling mill rolls. This device has a rotating part, which has four open pockets on its circumference. These are rotatable about a horizontal axis that the pockets, which the Contain stopper, lie one after the other in the transport path of the pipe when this moves long the predetermined transport path, so that the tube receives the first plug with its front end and carries it into the space during the rolling of the tube. After finishing the rolling process and before stripping the Pipe, the plug falls down a channel from the space between the rolling mill rolls due to its own weight, - and although to a diametrically opposite lower pocket of the rotating part. After the stripping process has ended, the rotating part rotates continues and sets the second stopper contained in the next pocket in the predetermined transport path when the process is repeated will.

409807/0460

However, such a device suffers from several disadvantages. So is particular Leave a gap in the predetermined transport path so that when the rolling of the seamless tube is finished, the Plug member can move from here due to its gravity on the chute or chute down to the lower pocket of the rotating part. Since the rotating part is arranged in such a way that its pockets lie one after the other in the predetermined transport path of the heated seamless tube, when this moves into the space between the rolling mill rolls, it is necessary that the front end of the tube, that has received the stopper moves across the gap, and it is completely unsupported during passage through the gap or unsupported, which is undesirable. Furthermore, the rotating part only contains a pair of plugs. In contrast, it is desirable that the rotating part can receive and hold a plurality of stopper pairs, so that it is possible to replace the stopper, to cool and lubricate while the plug mill is in operation.

The invention is therefore based on the object of avoiding these disadvantages and to provide improved automatic means for adding and removing plugs to and from the piercer.

The features of the device created to solve this problem result from the claims.

The invention provides an automatic stopper feeding device created, in which the stopper during its way at the end of the heated tube along the predetermined transport path into the space is supported or stored between the rolling mill rolls by means of a guide device and in which a plurality are alternately supplied to the gap by pairs of plugs

409807/0460

can, whereby the contained in the automatic feeder Plugs can be removed and replaced, lubricated and cooled.

It has been shown according to the invention - when the rotating part is close to the predetermined Transport path is arranged such that upon rotation of the rotating part, a plug from a pocket to the inlet guide member is discharged, one end of which is located near the space between the rolling mill rolls · - that the plug during its Forward movement at the end of the heated seamless tube into the space in between is supported between the mill rolls by the inlet member and that further the inlet guide member is easily so formed can be that it has a space in it, so that the plug after the completion of the taking place by the rolling mill rolls Rolling the seamless pipe and before the stripping of the pipe by the stripping rollers due to its gravity Gap between the rolling mill rolls can be eliminated and can be returned to an unoccupied pocket of the rotating part.

The invention is based on a plug rolling mill to reduce the Wall thickness of a heated seamless tube to the desired caliber with a guide device for guiding the heated seamless The pipe along the predetermined transport path in the rolling train, with a pair of grooved rotatable rolling mills, which are transverse to the are arranged predetermined path, with a first gap formed between the rollers of these in the rolling position, the forms part of the predetermined transport path and is dimensioned such that the rolling mill rolls the pipe in the grooves grip, whereby when they are rotated the tube is pulled through the first space, with a device for rotating the rolling mill rolls in the rolling position, with a retractable one

409807/0460

Device for moving the pipe along the predetermined transport path into the first interspace, with a pair of arranged transversely to the transport path and downstream with respect to the rolling mill rolls Stripping rollers which have a second intermediate space between them, forming part of the transport path, and in their stripping position Return the seamless tube after rolling through the rolling mill rolls along the transport path, with a extending along the transport path and attached to one end of the mandrel, the free end of which detachably receives a plug and that runs through the second gap between the doctor rollers extends, wherein the plug is arranged in the first space between the rolling mill rolls.

The invention is characterized by a device for releasable Placing a plug in the first space on the piercer, by an egg flow guide member, which is in the transport path upstream of the between the rolling mill rolls provided first gap is arranged near this, by a Drehteii, which several around its circumference in Distance from each other as well as provided near the transport route open Has pockets and is arranged such that a plug contained in one of the pockets can be discharged into the inlet guide member from where from the plug from one end of the seamless tube moving along the transport path into the first space between the Rolling mill rolls is supported and brought into abutment with the free end of the piercer, by one formed by the inlet guide member closable third space, which is arranged near the rolling mill rolls and is dimensioned such that a plug can move therethrough, by means for closing the third space during the presence of the plug in the

409807/0460

EirilaßführungsgUed, by a device for opening the third Intermediate space, so that a plug falling under its gravity from the first intermediate space after the action of the rolling mill rolls can move through and through a device to lead plug moving through the third space in an unoccupied pocket of the turned part.

According to a preferred embodiment of the invention, the inlet guide member is to create the closable space, designed such that it is between a rolling position and a Can move stripping position, wherein in the rolling position one end of the inlet guide member near the first space between the Rolling mill rolls is, during this end in the stripping position, at a distance from the first intermediate space between the rolling mill rolls is arranged to create the third gap. Advantageously, the inlet guide member is one in a channel between two Positions worsening channel part, which by means of a hydraulic Stamp can be actuated or moved between these two positions.

The rotating part preferably has an odd number around its circumference Pockets, whereby one of the pockets is always empty or free. Preferably, the rotating part has at least five pockets, which can hold or receive at least two pairs of plugs at the same time.

According to one embodiment of the invention, the rotating part is around a horizontal axis rotatable, with the plug from an upper one Pocket moved into the inlet guide member and through the stopper guide means is guided into an unoccupied deeper pocket of the rotating part. The guide device expediently has a Gutter on. According to a preferred embodiment of the invention is

409807/0460

the rotating part is designed as a rotating drum which has arms extending therefrom. These form or limit pockets. With such a device it is extremely easily possible for the senses to lead the plug discharged from the third space directly into an unoccupied pocket.

According to a further embodiment of the invention, the rotating part has the shape of an endless chain conveyor belt which has extension arms at joints which form or limit the pockets. With such a device it is possible to provide a large number of pockets in the rotating part, so that a large number of pairs of plugs can also be held or received. It has been found convenient to provide a Stoßeinrichtuog near the bottom of the trough to the trough to push the plug down moving in an empty pocket in the lower endless conveyor belt.

If, as previously explained, the rotating parts are arranged near the predetermined transport path , means are suitably provided by means of which a pocket can be temporarily closed in order to retain the plug therein and to prevent it from moving into the inlet guide member. This enables the worker, if he so wishes, to prevent any particular special plug from entering the channel-shaped inlet member. Such a situation can arise if the worker perceives that the plug is wrongly sized, damaged in some way, or unsuitable for the next operation of the plug mill. Preferably, the rotating member rotates through a water bath to cool the plug returned from the first space between the mill rolls. The presence of multiple plugs in the rotating part ensures that more time is available for cooling, replacing and lubricating the plugs.

The conventional plug mill shown in the drawing has a pair of grooved rolling mill rolls 1, which are slightly elliptical in shape Grooves 2 are provided. The upper roll 1 is in this case from a rolling position shown in FIGS. 1 and 2 into a rest position, ie. H. in the wiping position is movable. The mill also faces downstream With regard to the rolling mill rolls 1, a pair of stripping rollers, not shown, which are also in a working position (stripping position) and can be brought into a rest position (rolling position). A water-cooled piercer 3, which is fastened at one end, extends through the space between the stripping rollers while the other end is arranged to releasably insert a plug 4 in the space between the mill rolls 1 can hold.

A guide channel 5 is arranged upstream with respect to the intermediate space located between the rolling mill roller η 1. This holds the heated seamless tube 6 , which is to be passed through the plug rolling mill in order to reduce the wall thickness to the desired caliber. BIe channel 5 has in its longitudinal direction a plurality of spaced-apart, transverse intermediate spaces in which liftable rollers, not shown, are arranged. In its raised position, these can rotate the seamless tube 6 in the guide channel 5 axially by an angle of 90. An inlet guide 7 is arranged between the end of the inlet channel 5 and the rolling mill rolls, the pipe 6 moving along the channel 5 into the space between the rolling mill rolls 1 moving over this inlet guide 7 and being pulled through the gap when the rolling mill rolls 1 move into rotate in the direction of the arrow shown in FIG. To adapt to seamless pipes 6 of different diameters, the inlet

⁶¹⁹⁵ 409807/0460

guide 7 by means of a hydraulically actuated ram 8 vertically adjustable.

As explained, the plug rolling mill described is conventional Art and is used to reduce the wall diameter of the seamless pipe 6. It works like this:

A plug 4 of suitable size becomes releasable at the end of the piercer 3 attached. The rolling mill rolls 1 in their operating position are rotated and the seamless tube 6 in the channel 5 becomes at high speed by means of a trailing ram, not shown, along the channel 5 into the space between the Rolling mill rolls 1 pressed, from where the pipe 6 by means of the rolling mill rolls 1 through the spaces and over the plug 4 as well is pulled over the piercer 3. The mill rolls are then moved into their rest position, the stripping rollers are in their working position spent and the plug 4 is removed from the end of the piercer 3. The wiper rollers then become actuating the seamless Pipe 6 is returned to the channel 5, where it is twisted or rotated by 90 by means of the liftable rollers. A plug 4 then becomes of slightly larger dimensions attached to the end of the piercer 3 and the rolling and stripping process repeated.

As can be seen from FIGS. 1 and 2, the plug 4 is the end of the piercer fed in the spaces between the rolling mill rolls 1, by means of a plug feeder, through which he also after the seamless tube 6 has passed through the rolling mill rolls 1 in the rolling position and before they reach their stripping position take, is returned. The device has a "cartridge" rotor, i.e., a drum rotor 10 having arms 11, which are a

⁶¹⁹⁵ 409807/0460

Limit number of peripheral pockets 12. These are designed in such a way that that they receive stoppers 4 and are rotatable about a horizontal shaft 60 supported in a bearing 13. Run through 13 when rotating the rotor the pockets 12 a water trough formed by a housing 14. To easily remove a plug 4 from the device to be able to, the housing 14 has a pivotably arranged door 15 which is attached to a. Tab projection 16 is lockable. This can the stopper 4 roll down a ramp 17 after the door 15 is opened. In this way a plug 4 can easily be removed from the device and replaced by a new plug 4 when the pocket 12 is at rotating rotor 10 is lifted out of the water trough. The device is arranged near the inlet guide 7, which see between a rolling position shown in Fig. 1, in which you one end in the Near the rolling mill rolls 1, and can move a stripping position shown in phantom in Fig. 1, in the between the end the inlet guide 7 and the rolling mill rolls 1 a space is formed. The gap is of sufficient size so that a plug 4 falling from the end of the piercer 3 in the space between the rolling mill rolls 1 can move through it due to its gravity. Movement of the inlet guide 7 between the two mentioned Stellurg is due to the actuation of a hydraulic Stamp 18 allows the inlet guide. 7 is fastened to the piston rod 19 of the hydraulic motor 18 by means of a holder 20. The inlet guide 7 slides in support guides 21 and is controlled in its movement by means of a stationary guide rod 22, along which a part 23 welded to the guide 7 and provided with an eye slides.

Below the inlet guide 7 a channel 24 is arranged through which through the space between the end of the inlet guide 7

409807/0460

and plugs 4 falling through the rolling mill rolls 1 are returned to an unoccupied lower pocket 12 in the eotor 10.

When the device is in operation, a plug 4 rolls when it rotates Botor 10 out of an upper pocket 12 and moves through a space not shown in the wall in the Inlet guide 7 located in the wiping position through into the inlet guide 7 in. The inlet guide 7 then moves forward in the rolling position. When operating the rolling mill rolls 1 and the Ram, which presses the seamless tube 6 along the guide channel 5 and into the guide inlet 7, the plug 4 is removed from the front end of the seamless tube 6 added and in the space between the Rolling mill rolls 1 spent where the plug 4 at the end of the piercer is arranged. If there is a considerable part of the seamless Tube 6 has moved through the space between the rolling mill rolls 1, the inlet guide 7 is by means of the ram 18 in their Abstrelfstellung withdrawn, in such a way that the plug 4 after the completion of the rolling of the seamless tube 6 due to gravity through the space between the end of the inlet guide 7 and falls through the rolling mill rolls 1 into the channel 24. The channel 24 directs the plug 4 into a lower unoccupied pocket 12 of the Rotor 10. The stripping process is or is then carried out. The rotor 10 is then rotated a corresponding distance, so that the plug 4 in the next pocket 12, the slightly larger one is than the preceding plug 4 into which inlet guide 7 is moved, whereupon the inlet guide is brought back into its rolling position and the previously explained operation is repeated at the plug rolling plant will.

⁶¹⁹⁵ 4098 07/0460

When revolving around the eotor 10, each plug 4, from the plug rolling mill has been returned, cooled in a water bath and can be provided with lubricant, for example graphite, after cooling which is applied to the stopper 4 while the pocket 12 is in an upper position. The apparent from Fig. 2 Eotor 10 has five pockets 12 which can accommodate two pairs of plugs that are ready for operation at the same time. This allows the in the device located plugs 4 are not only easily replaced if they are worn or damaged, but it is also possible to use them to provide better cooling or better lubrication.

In the modified embodiment shown in FIGS. 3 to 6 the device comprises an endless conveyor chain 30 which is arranged on two chain wheels 31 and chain connecting links 32 as well Connecting arms 33 has. These form a multiplicity of circumferential pockets 34 which receive plugs 4. The use of an endless Chain conveyor 30 allows more pockets 34 to be provided and also ensures that more pairs of Plugs 4 are ready for use. The chain wheels 31 are each arranged on a shaft 9 mounted in a bearing 35, the lower Strand of the endless chain conveyor 30 for cooling the stopper 4 is moved by a water bath which is formed or limited by a housing 36 is.

Swivel rods 37 of the provided in the endless chain conveyor 30 chain connecting links 32 and connecting arms 33 have inner ones Rollers 38 and outer rollers or balls 39 on. The inner rollers in the upper run of the chain conveyor 30 run on one on one Support 55 arranged plate 40 and are received by the teeth 41 of the sprocket 31. The outer rollers 39 carry the chain

409807/0460

conveyor 30 as it passes along a top plate 42 and an am Lower plate 43 attached to the housing 36 of the water bath. The upper plate 42 has a space 54 through which the rollers 39 can pass downward around the chain wheels 31 as the chain conveyor 30 passes through.

A plug guide 44 is arranged near the inlet guide 7, wherein the inlet duct 7 has an opening (not shown) in its wall so that the plug 4 can pass through. The plug guide 44 has two fingers 45 which are attached to a shaft 47 by means of blocks 46. Here, the shaft 47 is rotatably mounted in bushes 56. For this reason, the fingers 45 on the shaft 47 can be of an in Fig. 4 visible position in which they store the plug 4 and of of the upper pocket 34 into the inlet guide 7, in one position are twisted in which they prevent the plug 4 from passing through. If the passage of the plug 4 into the inlet guide 7 is not possible or prevented, the plug 4 is therefore driven back again, moves down in pocket 34 around sprocket 31, rolls out of the pocket 34 and is, as will be explained in the following, by a plunger 51 into the next front adjacent one Pocket 34 encountered. In this way, the plug 4 is guided past the inlet guide 7.

Exactly as with the embodiment according to Flg. 1 and 2 can be the Inlet guide 7 between a rolling position and a stripping position move, the movement of the inlet duct 7 is achieved due to the actuation of a hydraulic ram 18, via a Piston rod 19 attached to the base of guide 7; latter slides by means of a socket 20 between the two mentioned positions

⁶¹⁹⁵ 409807/0460

In a support guide 21. The inlet guide 7 is in its movement guided by means of a guide rod 21, along the one having an eye Part 23 which is welded to the bottom of the inlet guide 7 slides.

The arranged below the inlet guide 7 channel 24 passes through the space between the end of the inlet guide 7 and the rolling mill rolls 1 falling stopper 4 near the unoccupied one free lower pocket 34 in the endless chain conveyor 30, whereupon the Stopper 4 by the actuation of the hydraulic piston 50, which at the end of the piston rod 52 has the plunger 51 touching the stopper 4, In the pocket 34 is pressed. The device according to FIGS. 3 to 6 corresponds in its function to that of the device according to FIG. 1 and 2.
