Publication number: 20230201900Abstract: A device for handling mandrel rods in a rolling plant for rolling seamless tubes comprises an inserter. The inserter moves a mandrel rod in a rolling direction such that the mandrel rod, starting from an initial state, is pushed into a tube blank situated upstream of the mandrel rod. A retaining device has a fixing unit that is movable along the rolling line and is designed to temporarily hold the mandrel rod at an action point at a rear end of the mandrel rod and to carry out a working stroke. The mandrel rod can be inserted into the rolling mill in the rolling direction and pulled out of the rolling mill counter to the rolling direction by the retaining device. The retaining device is designed such that the starting position of the fixing unit lies between the two ends of the mandrel rod in the initial state.Type: ApplicationFiled: June 30, 2021Publication date: June 29, 2023Applicant: SMS group GmbHInventors: Walter KIRCHNER, Paolo MARIN, Patrizio RINALDI

Publication number: 20200055080Abstract: A method and a device for spray painting a workpiece uses an application device. The workpiece has at least two components that are movable relative to each other which are at least arranged region by region or meshing with each other such that, dependent on the relative position of the components, at least a subregion of one of components is mounted shaded so that the subregion is inaccessible for spray painting by the application device. The method and the device for the spray painting of workpieces, allow a fast, complete and cost-effective painting of a workpiece. One of the components is moved during the spray painting by means of an actuator such that the subregion of the component is displaced so that the subregion is not shaded and is accessible for spray painting by the application device.Type: ApplicationFiled: August 13, 2019Publication date: February 20, 2020Inventor: Marc Walter KIRCHNER

Publication number: 20190275682Abstract: A method for handling a wheel which is carried by a spindle in which a robot arm grips the spindle at a robot gripping position and removes same from a transport vehicle. Since the wheel is not directly gripped by the robot arm, damage to the wheel that could be caused by clamping of the robot arm on the wheel is avoided. Preferably, before or during the removal of the spindle from the transport vehicle, a locking element on the transport vehicle releases the spindle.Type: ApplicationFiled: March 5, 2019Publication date: September 12, 2019Inventor: Marc Walter Kirchner

Patent number: 9789522Abstract: In order to improve the quality of pipe-like work pieces, a rolling mill has at least two successive consecutive rolling stages that have mandrel rods. A threading line for the mandrel rod of the second rolling stage can lie on an extraction line for the mandrel rod of the first rolling stage. The same advantage can be achieved in a rolling method for the production of pipe-like work pieces, comprising at least two successive consecutive rolling stages, wherein the two rolling stages perform the rolling with the use of mandrel rods. The work piece is brought from the mandrel rod of the first rolling stage onto the mandrel rod of the second rolling stage, without entirely emptying an interior of the work piece and/or without changing the direction of movement of the work piece or braking the work piece in the meantime and accelerating it once again.Type: GrantFiled: February 11, 2014Date of Patent: October 17, 2017Assignee: SMS group GmbHInventors: Walter Hoeffgen, Walter Kirchner, Norbert Theelen
