A machine for bending oblong elements, preferably metal, includes a feed unit configured to feed at least one of the oblong elements along a longitudinal axis. A bending device is located downstream of the feed unit and a curving unit is disposed downstream of the bending device and is configured to curve the oblong element along part of its oblong development.

The invention discloses a metal pipe bending cutting machine, which comprises a machine tool base. A main motor cavity is symmetrically arranged at the center of the machine tool base. A main motor is fixedly located in the lower wall of the main motor cavity. A main power shaft is provided, a first bevel gear is fixed on the main power shaft, and a second bevel gear is meshed with the first bevel gear. The invention has the advantages of simple structure, convenient maintenance and convenient use. The metal pipe is automatically processed by the stamping mechanism, and the bending and stamping process can be built in. At the same time, a high-speed cutting device can be built in, so that the metal pipe can be cut and processed after the bending process is completed, thereby speeding up the processing and greatly improving production efficiency, Reduce the workload of workers and save production costs.

A disclosed forming system is a forming system which expands and forms a metal pipe in a die. The forming system includes a preliminary forming apparatus which preliminarily forms a metal pipe material, a forming apparatus which includes a gas supply unit which supplies gas into the preliminary-formed and heated metal pipe material to expand the metal pipe material and a main body portion to which the die is attached, and a cutting device which cuts at least a portion of the formed metal pipe. The gas supply unit is provided so as not to be disposed on a first straight line which connects the preliminary forming apparatus and the main body portion in a plan view and a second straight line which connects the cutting device and the main body portion in a plan view.

A damage evaluation device for a press-forming die includes: evaluation dies installed in a pressing device configured to press-form a metal material; and an observation device configured to observe damage behavior of a die steel material and surface coating constituting the evaluation dies. The evaluation dies include: a perforating unit configured to form a hole in the metal material; a first shearing unit configured to shear the metal material in which the hole is formed into a predetermined metal component shape; and a second shearing unit configured to separate a metal component from the metal material, and dies of the perforating unit, the first shearing unit and the second shearing unit are formed of the die steel material and have a structure that enables replacement with another die made of predetermined material and applied with predetermined surface coating treatment.

A method for producing a component element for a furniture fitting, in particular a rail, includes the following steps to be carried out in chronological order: providing a planar sheet having a longitudinal extension, two top surfaces and two side surfaces spaced apart by a width of the sheet, as a semifinished product of the component element. The sheet has a wall thickness in the range of 0.5 mm and 1.5 mm, and is formed, preferably by an embossing stamp and/or an embossing roller, on at least one top surface with an indentation. The indentation is arranged transversely, preferably substantially orthogonally, to the longitudinal extension. The sheet is bent such that, in a cross section orthogonal to the longitudinal extension, a profile of the component element arises, and the bent sheet is mechanically separated in the region of the indentation.

The disclosure relates generally to pipe preparation and processing, more particularly, to a loading and unloading station for moving pipes through the preparation and processing stages of production. The pipe loading and unloading station may include an upstream ramp including a plurality of movable pipe separator tabs, a downstream ramp including a plurality of movable backstop tabs, and a conveyor located between the upstream ramp and downstream ramp and including a plurality of movable ejectors.

A computer numerical control (cnc) bending machine used to bend and then cut a specific programmed profile from a long length of cable comprising: a base, a carriage, a bend head and a saw; the carriage includes a spindle to rotate the cable, the carriage is also able to transport the cable in a linear fashion; the bend head comprises a clamp and a wiper roller and a bend die; after a last bend is formed, the clamp and wiper roller are retracted away from the bend die; the carriage is then able to then transport the cable forward away from the saw, the spindle is then able to rotate the cable out of the plane of the bend, the carriage is then able to transport the cable back toward the saw; the saw is then able to sever the cable such that a last leg length adjacent to the last bend which is shorter than the fixed distance between the saw and the bend die.
