  • Patent number: 9381554
    Abstract: In a method for producing seamless pipes, a hot hollow block created previously in a piercing mill is stretched by means of a continuous rolling mill on a mandrel bar to form a parent pipe and the parent pipe is fed directly to a stretch reducing mill or sizing mill as a finishing mill, while forgoing an extracting mill and a reheating furnace, and is rolled there to the required final pipe diameter. The hollow block is pre-dimensioned in its length in such a manner that only a single length is produced as the required parent pipe length during the stretching in the continuous rolling mill and the parent pipe is pulled off of the mandrel rod by the finishing rolling during the subsequent finishing rolling, wherein the rolling is performed using rolling mill components that are designed in the dimensions thereof for handling single lengths.

  • Patent number: 8210013
    Abstract: In a method to replace a pair of rolls of a rolling mill stand during a downtime period, worn rolls fitted with chocks are extracted from the mill stand and positioned on means of displacement that bear a pair of new rolls without chocks. The method sets the means of displacement in motion so that the worn rolls are aligned with a chock extraction device. The chock extraction device is used to remove the chocks from the worn rolls. The means of displacement are actuated so that new rolls are now aligned with the chock extraction device. The chock extraction device is used to reinstall, on the new rolls, the chocks. After the new rolls have been fitted with the chocks, the new rolls are inserted in the mill stand so that the downtime period is reduced and the number of chocks in service is likewise reduced.

    Abstract: A variable crimp on flange (COF) tool is provided for engaging and attaching a weather strip and like structures onto a flange. The COF tool includes a housing with two or more crimp rollers that project therefrom. For example, a fixed roller is mounted to the housing to rotate in a first direction, while a movable roller is mounted to the housing to rotate in a second, opposite direction. The movable roller is axially offset from and movable relative to the fixed roller. A driving mechanism, such as a pneumatic motor, is encased within the housing, and operates to rotate the crimp rollers. A biasing mechanism, such as a pneumatic piston assembly, is also encased within the housing, and operates to move the movable crimp roller relative to the fixed crimp roller. The COF tool is engineered such that the crimp speed, crimp rate, and crimp pressure are independently adjustable.

    Abstract: The invention relates to a method for changing sets of top rolls, lateral rolls, and a bottom roll, and mounted in chocks of a welding stand of a continuously operating longitudinal tube welding machine. The inventive method enables the rolls to be changed faster, using less appliances. Said method comprises the following steps: the top rolls are lifted; a dismantling/transport means is placed beneath the top rolls; the top rolls are lowered onto the dismantling/transport means and deposited on the same; and, once the top rolls have been removed, the dismantling/transport means is laterally withdrawn.

  • Patent number: 7165432
    Abstract: A device for changing pairs of work rolls and/or pairs of backup rolls of roll stands, wherein the rolls are each supported in chocks and are movable out or in by a lower back up roll supported on a track and wheels. The work rolls on the drive side of the roll stand can be coupled to a hydraulic piston-cylinder actuator that is dimensioned in is stroke length for the removal or installation distance and can be uncoupled when it has been withdrawn by the required distance. A roll changing frame can be coupled to the actuator and, when the upper backup roll and the roll changing frame are supported on the lower backup roll, the pair of backup rolls can be moved out or back in. The actuator is coupled to a pusher with connecting arms aligned with ends of the rolls. The actuator is arranged on the drive side of the roll stand and is coupled to the pusher through a piston rod.

  • Patent number: 7010952
    Abstract: A device for holding at least one roller of a rolling machine that can rotate about a rotational axis includes two holding arrangements that can be arranged on opposite faces of the roller viewed in the direction of the rotational axis. The device further includes at least two coupling parts each configured for a coupled mode and an uncoupled mode. A first of the two coupling parts has at least one, preferably essentially straight first groove, and has a second groove that does not run parallel to the first groove. A second of the two coupling parts includes a first coupling element and a second coupling element, wherein the first coupling element projects further outward from the second coupling part than the second coupling element. In at least one implementation, the roller can be detached or removed from the holding arrangements when the holding arrangements are in uncoupled mode.

  • Patent number: 6837090
    Abstract: A rolling train for the continuous rolling of strand shaped products has at each rolling location a pair of fixed stations which are closely spaced and have rails such that a mill stand at one station can be displaced away from the rolling line and be replaced at that location by a mill stand at the other station. The mill stands can be connected to the respective control and operating media sources by lines which are unreeled as the mill stand is moved away from the operating position or reeled up as the mill stand is moved into an operating position.

  • Publication number: 20040231389
    Abstract: The invention relates to a device and a working method for automatically changing the sets of rolls comprising work rolls, backup rolls and intermediate rolls of a single-stand or multi-stand strip rolling mill, by means of a roll changing carriage (2) which can be displaced transversely with respect to the strip rolling stand (1) and a removal crossbar (3) provided for the removal of the set of backup rolls (10/11). In order to shorten the roll changing times and to automate the changing of the rolls, it is proposed that the removal crossbar (3) can be positioned on the roll changing carriage (2) and is provided with wheels (4) on which the removal crossbar (3) can be moved in working steps according to the invention out of the roll changing carriage (2) on guide rails (5) running parallel to the rolls (10/11) into the strip rolling stand (1) on the intermediate roll rails (8), and can be pulled out of the strip rolling stand (1) together with the set of backup rolls (10/11).

  • Patent number: 6792783
    Abstract: A quick change cassette system for a multi-roll leveler, such as may be used to flatten strips of material. The quick change system is designed for use with a leveler having an upper and lower cassette assembly containing upper and lower work rolls, respectively. The quick change system is also particularly suited for use with a lower work roll cassette that is mounted to the leveler in a hanging arrangement. A cart is mounted to the bottom side of the lower work roll cassette. Wheels are attached to a bottom portion of the cart to guide the cart into and out of the work envelope of the leveler along a set of guide rails. The cart can be moved manually or by means of a motor, cylinder, or other actuator. The cart remains attached to the lower work roll cassette during operation of the leveler. An upper work roll cassette may also be removed or installed to the leveler along with the lower work roll cassette.

    Abstract: The present invention relates to a method and apparatus for changing ring rolls of a bar and wire rod mill which makes roll changing work easy and in particular to a method for changing only the ring rolls without disassembling the housing in accordance with an optimum process. The method for changing ring rolls in a bar and wire rod mill having a plurality of roll assemblies incorporated into a housing and arranged in equiangular positions in circumferential direction comprises the steps of disengaging the interference fit between the spent ring rolls and the roll shaft, withdrawing the spent ring rolls by moving the roll shaft in an axial direction, changing the spent ring rolls with new ring rolls in the housing, inserting the roll shaft into the new ring rolls, and engaging the new ring rolls in interference fit with the roll shaft.
