摘要： A method for automatic calculation of a pass schedule in the radial forging of steel tubes in a radial forging machine is disclosed. The forging machine includes at least four forging tools arranged around the circumference of the workpiece, which are set up and adapted for synchronous forging operation over at least a partial length of the workpiece and/or the tube. Starting parameters for the forging process, preferably radial forging process, are entered into a pass plan calculation program and target parameters for the radial forging process are defined. The pass plan calculation program calculates a pass plan or a forging sequence on the basis of these start and target parameters.

摘要： In a method for thickening a plastically deformable hollow body wall of a hollow body, with effective radial support of the unthickened hollow body wall on an outer supporting face of an outer mold and with effective radial support of the hollow body wall on an inner supporting face of an inner supporting body, the hollow body is acted on by a compressive force by two application members at application points by moving the application members towards one another in the axial direction with a compressing movement. The application points on the hollow body are distanced from one another in the axial direction. An expansion space of the outer mold is arranged between the application points. Due to the compressing movement of the application members, material of the hollow body wall between the application points is plasticised in the region of the expansion space of the outer mold, and plasticised material of the hollow body wall flows into the expansion space of the outer mold, thus thickening the hollow body wall.

摘要： A system monitors vibration activity in a press machine environment and generates a signal indicative of vibration level severity. An accelerometer can provide measured peak acceleration data that serves as an indication of vibration level. The vibration measurement, is compared to a reference vibration level that corresponds to a run condition of desired operating parameters. A controller controls the press machine shutheight in accordance with the differential expressed in the comparison result. The consequent shutheight adjustment effects a change in the vibration activity that acts as a correction to the deviation in vibration behavior expressed by the differential.

摘要： Thermodynamic material testing apparatus and a method for use therein which are capable of controllably inducing very large strains in crystalline metallic specimens. The apparatus prevents longitudinal flow elongation, that otherwise results in conventional testing systems when a specimen is compressively deformed, from occurring but permits sideways material flow outwards from a specimen work zone. The specimen is rotated between successive deformations through a predefined angle, e.g., 90 degrees, in order to present strained specimen material to opposing anvil faces for a next successive compressive deformation. Rotating the specimen between hits and hence compressing previously strained material permits the same work zone material to be deformed many times with very high strains induced therein.
