Forming tool and method for producing a component
A forming tool includes at least one first die half where the first die half has an insert part which is designed to move a finished component out of the first die half along a direction of motion where a displacement direction of the insert part is inclined relative to the direction of motion.
Method for manufacturing a camshaft for an internal combustion engine by expanding a tubular element with a high pressure fluid and simultaneously compressing the tubular element axially
In a method for manufacturing a camshaft for an internal combustion engine a metal tubular element is expanded within a mold with the aid of a fluid at high pressure fed into the tubular element and with a simultaneous axial compression of the tubular element. The cams of the camshaft are formed in subsequent steps, starting from intermediate cams and ending with end cams. In a first step of the method, the intermediate cams are formed in a first mold. In a subsequent step, the end cams are formed within auxiliary molds which surround, only throughout a predetermined length, end portions of the tubular element which project from the mold which surrounds the already formed intermediate cams. In this subsequent step, the tubular element is compressed axially by axially displacing two clamp members, which grip and surround completely, throughout a predetermined length, the end portions of the tubular element which project outwardly from the auxiliary molds.

SYSTEMS AND METHODS FOR ELECTROMAGNETIC FORMING OF CONTAINERS
Systems and methods of forming articles using electromagnetic radiation are disclosed. In some aspects, the system includes a plurality of forming modules movably mounted relative to an infeed mechanism. The infeed mechanism is configured to supply pre-form articles to the plurality of forming modules, and each of the plurality of forming modules includes a multi-segment mold disposed about an electromagnetic coil. The electromagnetic coil is configured to impart an electromagnetic force on the pre-form articles when supplied with electrical energy that urges the pre-form articles into contact with the multi-segment mold to produce the formed containers.
FORMING DEVICE AND FORMING METHOD
By the control of a controller, a gas is supplied into a metal pipe material from a gas supply part so as to expand a part of the metal pipe material in sub-cavity parts, and then a driving mechanism is driven such that expanded parts of the metal pipe material are pressed by an upper die and a lower die to form flange parts. In addition, by the control of the controller, a gas is supplied into the metal pipe material after the formation of the flange parts from the gas supply part so as to form a pipe part in a main cavity part. In this manner, the controller controls the gas supply part and the driving mechanism, and thus flange parts and a pipe part having a desired shape can be easily formed.

HOT METAL GAS FORMING AND QUENCHING SYSTEM AND PROCESS THEREFOR
A hot metal gas forming and quenching system and process therefor are provided. The system includes a hydraulic press, a die assembly, a rapid heating module and a rapid cooling module. The die assembly includes a progressive die which can realize the hot gas bulging and rapid cooling of the workpiece. Through the above system and the process, making pipes with uncoated plates has a lower cost than with coated and plated steel plates, with fewer structural defects and process risks. By using a progressive die, a resistance heating process, and hot gas bulging and quenching processes are performed in parallel, and the material is loaded progressively, thereby having a fast pace and a greatly improved efficiency. A heating state of parts is fully protected, oxidation is avoided, and no coating is required. After the workpiece is formed, it can be directly welded to a car body without shot blasting.

Method for forming tube with high internal pressure and low external pressure, and forming machine
Disclosed is a method for forming a tube with high internal pressure and low external pressure. The method comprises: putting a tube to be formed into a cavity, such that a bulging area (15) is formed between the tube to be formed and an inner wall of the cavity; continuously injecting a low-pressure fluid into the bulging area, and then injecting a high-pressure fluid into the interior of the tube to be formed, the high-pressure fluid creating a pressure on an outer wall of the tube to be formed such that the tube to be formed starts to expand to the bulging area; stopping the supply of the low-pressure fluid when the tube is bulged to conform to the inner wall of the cavity; and taking the formed tube out to complete a working cycle. Further disclosed is a forming machine for forming a tube according to the above method. According to the machine for forming a tube with high internal pressure and low external pressure, a mold body (1) is provided with a first through hole (13) and a second through hole (14) for circulating a low-pressure fluid into and out of a bulging area, so as to create a certain pressure P1 on the tube and ensure uniform bulging of the entire tube, thereby achieving a better forming effect.
