Tube processing systems for bending and notching a tube fed from a feed position. The tube processing system includes a notching system and a bending system. The notching system is configured to cut a notch in the tube. The bending system is disposed between the notching system and the feed position and is configured to bend the tube. The notching system includes a cutting head and a positioning system. The cutting head is configured to cut a notch in the tube. The positioning system movably supports the cutting head and is configured to move the cutting head relative to the tube to a selected cutting position. The bending system includes a bending die and a clamp. The bending die is rotationally driven to bend the tube. The clamp is configured to secure the tube to the bending die.

Provided are a forming method and a forming apparatus which can secure strength after forming while suppressing deformation. The forming method of the present invention includes a burring step and a pressing step. In the burring step, a branch pipe is formed by causing a cylindrical peripheral wall of a cylindrical member (workpiece) having the peripheral wall to project in an outside direction in a tubular shape. In the pressing step, a distal end surface of the branch pipe is pressed toward a proximal end portion of the branch pipe. In the pressing step, the distal end surface of the branch pipe can be pressed by an end surface pressing punch in a state where a burring punch is inserted in the branch pipe.

A soldering nozzle (100) for selectively soldering assemblies by means of molten solder supplied through a soldering nozzle (100) from a solder bath. The soldering nozzle (100) is designed as a deep-drawn part. A method for the production of a soldering nozzle (100) is specified as well, including the provision of a blank (401); the drawing of the blank (401) through at least one female die (411, 421) by means of at least one male die (413, 422, 431) to produce an oblong shape (439) of locally annular or substantially annular cross-section, with a first end (436) corresponding to an action point of the male die (413, 422, 431) and a second end (437) corresponding to an introduction cross-section of the male die (413, 422, 431), the cross-section preferably increasing from the first end (436) towards the second end (437); and the formation of an opening (446) at the tip end (436).

A press working method capable of forming a perforated portion with higher accuracy with respect to a workpiece being a ductile material. The press working method may comprise applying a first load to a workpiece being a ductile material with a press member to apply a preload within an elastic region of the workpiece, and then applying a second load exceeding the first load to the workpiece with the press member to provide a perforated portion in the workpiece, wherein the elastic region is larger than 0 MPa and is equal to or less than a limit shear stress value at which the workpiece is elastically deformed, the workpiece is a pipe made of metal, and the first load and the second load are applied in a state where an inside of the pipe is hollow.
