摘要： A method and a device for spin forming includes a workpiece set in rotation with a spindle and at least one outer roller is positioned at an outer side of the workpiece. With material thinning, an axially extending lateral region of the workpiece is shaped. At least one inner roller is positioned at an inner side of the workpiece with an inner support, which is displaceable axially and radially relative to the axis of rotation independently of the outer roller. The inner support with the inner roller and an outer support with the outer roller are displaced individually with a CNC control unit, forming at the lateral region a defined wall thickness profile with different wall thicknesses between the at least one outer roller and the at least one inner roller.

摘要： In a method for closing open ends of tubes, an open tube end is closed using spin-tubing methods known in the art. Following the tube end closing, a concavity is formed in the tube end in a tube end forming machine. The tube end is brazed with the tube end facing upright, so that the braze alloy pools in the concavity, strengthening the tube end.

摘要： With the method for manufacturing a composite brake disc, which includes a brake disc chamber and a friction ring having an inner profiling, a brake disc chamber blank is introduced into the friction ring. The brake disc chamber blank is then formed into the inner profiling via at least one embossing tool. A composite brake disc permitting a good torque transmission between the friction ring and the brake disc chamber can be manufactured in a cold-forming manner in this way. The forming-in can take place in a hammering manner, in particular by successively implementing a plurality of embossing steps in the region of different profile gaps of the inner profiling. Axial stops can also be simultaneously produced on forming-in. The axial stops serve to stop the brake disc chamber and the friction ring (3) are prevented from axially sliding apart.

摘要： Forming methods of one-piece weldless wheels made of metal sheets including the steps of rolling, forming a primary wheel rim and a primary wheel disc, roll forming, compressing and shaping, in order to obtain one-piece weldless wheels. The methods can form weldless wheels by rolling, cold roll forming and cold extruding, which can reduce energy consumption by 45-55% and cut down material cost by 5-15% while improving strength of the wheel by 20-30%. A wheel with different thicknesses can be formed by the methods and can meet the requirements on mechanical strength. The methods can improve the precision of the wheel and minimize the swing value and jerk value. The wheel produced is safer, and the regular air tight test on the wheel is not necessary.

摘要： According to a spinning forming device, while a plate is rotated by a rotating shaft, a transform target portion of the plate is pressed by a processing tool and locally heated by a heater that performs induction heating. The heater includes a coil portion having a doubled circular-arc shape and is inclined by an inclining device relative to a direction from the rotating shaft toward the processing tool. A measuring unit measures distances each from the coil portion to an outer peripheral original portion of the plate at a plurality of measurement points distributed in a circumferential direction of the rotating shaft. A controller controls the inclining device based on a measurement result of the measuring unit such that an angle difference between the coil portion and the outer peripheral original portion becomes not more than a predetermined angle.
