Rotating-head tube bender produces ultra-complex part shapes in one fast automatic cycle
8/4/2011
Scarborough, UK, August 4, 2011 --- Today, the all-electric tube bending machine innovator Unison launches a machine with a novel rotating tool head that allows left- and right-hand bending to be performed in one rapid and continuous automatic cycle. The development greatly enhances both the ability to fabricate extremely complex tubular shapes, and to increase production throughput.
Dubbed the Unison Breeze-Revolution, the new all-electric tube bender has two multiple-tool heads mounted on opposite sides of a rotating frame. After bending using one or more tools on the right-hand head, the head retracts and a combination of transverse and rotational movement then position the left-hand head for subsequent bending operations. This changeover can be repeated as many times as required.
Compared with conventional left-hand/right-hand bending machines with their completely separate tool heads, Breeze-Revolution switches between bending directions much more rapidly, shaving a great deal of time from part manufacturing operations. The high speed of operation is boosted by the use of simultaneous movement of multiple machine motion control axes during bending and head changes, as well as specially developed movement profiles. These take place automatically and transparently without any need for programming by the user, and help to deliver a machine that can perform combined left/right-hand bending at least twice as fast as the company's previous machine design.
The new machine also includes numerous further innovations that improve the precision and versatility of the bending capability. These mean that sub-1D bends (bends with a radius of less than one diameter of the tube) can be made - even on thin-wall tubing - with the benefit of wiper dies for quality shape forming and control of material flow. The machine also features a long pressure die and a moveable platen that makes it easy to create difficult shapes such as 180 degree bends in a single continuous and rapid operation.
Together, these features make Unison's Breeze-Revolution tube bender suitable for the most complex shape-forming applications in today's tubular parts industry, on all types of material from exotic alloy tubing to mild steel. The continuous automatic operation means that complex shapes can be made in a single cycle, providing great speed of production for cost-sensitive manufacturing sectors such as furniture or automotive production - where batch sizes might be medium to large. Equally, the all-electric nature of the machine with its software-controlled set-up makes the machine ideal for producing the most complex and precise part shapes in very small batches, as might be required in sectors such as aerospace manufacturing.
The machine's all electric, servomotor-controlled architecture gives comprehensive programmability throughout the entire part fabrication cycle. The position and forces of the tube bending dies can be precisely controlled - delivering the highest accuracy and quality of shape fabrication and end finish. These benefits are in addition to the well-known returns of low energy consumption and quiet operation of all-electric motion control architectures, compared with traditional hydraulically actuated bending machinery.
At the heart of Unison's new Breeze-Revolution machine range is a real-time machine and motion system based on the deterministic Ethernet-compatible Powerlink protocol. A 100 Mbits/second network links all of the servomotor drives required to control bending operations. The speed of the network makes it possible to coordinate the movement of the various servomotor axes used during bending - such as the carriage, plane of bend, and clamp roller - more rapidly, allowing Unison to improve the speed of bending.
The new machine also features Unison's major new release of programming and operating software. Among dozens of new and improved features in v10 of its Unibend package is a collision checking capability that helps users to program the machine for new parts. Programming itself can be achieved typically in a couple of minutes by entering new ISO, XYZ or YBC values (distance tube is pushed out, rotation, and degree of bend), linking from CAD or measuring machines, adapting an existing template, or interactively teaching the machine.
Unison can supply the new left-hand/right-hand rotating head architecture on all-electric tube bending machines capable of handling tubing with diameters up to 180 mm (7 inches).
The Federal's pistol slid into its holster and his sabre flashed out. He threw its curved point up in a splendid salute. Ferry saluted with his straight blade. Then both swords rang back into their scabbards, and Jewett whirled away toward his column. For a moment we lingered, then faced to the left, trotted, galloped. Over the fence and into the road went he--went I. Down it, as we crossed, the blue column was just moving again. Then the woods on the south swallowed us up. "All right, sir." that before. Meanwhile the parallelism between Thought and Extension was not exhausted by the identification just analysed. Extension was not only a series of movements; it still remained an expression for co-existence and adjacency.412 Spinoza, therefore, felt himself obliged to supply Thought with a correspondingly continuous quality. It is here that his chief originality lies, here that he has been most closely followed by the philosophy of our own time. Mind, he declares, is an attribute everywhere accompanying matter, co-extensive and co-infinite with space. Our own animation is the sum or the resultant of an animation clinging to every particle that enters into the composition of our bodies. When our thoughts are affected by an external impulse, to suppose that this impulse proceeds from anything material is a delusion; it is produced by the mind belonging to the body which acts on our body; although in what sense this process is to be understood remains a mystery. Spinoza has clearly explained the doctrine of animal automatism, and shown it to be perfectly conceivable;569 but he has entirely omitted to explain how the parallel influence of one thought (or feeling) on another is to be understood; for although this too is spoken of as a causal relation, it seems to be quite different from the logical concatenation described as the infinite intellect of God; and to suppose that idea follows from idea like movement from movement would amount to a complete materialisation of mind; while our philosopher would certainly have repudiated Mr. Shadworth Hodgson’s theory, that states of consciousness are only connected through their extended substratum, as the segments of a mosaic picture are held together by the underlying surface of masonry. Nor can we admit that Spinoza entertained the theory, now so popular, according to which extension and consciousness are merely different aspects of a single reality. For this would imply that the substance which they manifest had an existence of its own apart from its attributes; whereas Spinoza makes it consist of the attributes, that is to say, identifies it with their totality. We are forced, then, to conclude that the proposition declaring thought and extension to be the same thing570 has no413 other meaning than that they are connected by the double analogy which we have endeavoured to explain. “Oh, he’s welcome to it,” Sandy cried. “I’ve turned over a new leaf!” “But—are they?” He pulled a wire out a trifle from the sheath. The sergeant spent more time upon the oaths with which he embellished the counter-question as to how he should know anything about it, than would have been consumed in a civil explanation. "Doctor, he can't die. He mustn't die," said Shorty in agony. "The regiment can't spare him. He's the best soldier in it, and he's my pardner."

"Holy smoke, look there," gasped Monty Scruggs, as a company of rebel cavalry came tearing over the hill in front, to the assistance of their comrades. "That's about it," answered Shorty disdainfully. "That's the way with all cavalry, dad-burn 'em. They're like a passel o' fice pups. They're all yelp and bark, and howl and showin' o' teeth. They're jest goin' to tear you to pieces. But when you pick up a stone or a club, or git ready to give 'em a good kick they're gone, the devil knows where. They're only an aggravation. You never kin do nothin' with 'em, and they kin do nothin' with you. I never kin understand why God Almighty wasted his time in makin' cavalry of any kind, Yank or rebel. All our own cavalry's good for is to steal whisky and chickens from honest soldiers of the infantry. The infantry's the only thing. It's like the big dog that comes up without any special remarks, and sets his teeth in the other dog. The thing only ends when one dog or the other is badly whipped and somethin's bin accomplished." "Mmm." Reuben started out of the half-waking state into which he had fallen. It was late in the afternoon, the sunlight had gone, and a wintry twilight crept up the wall. Maude the dairy-woman was looking in at the door. It was about a month subsequent to this, that one morning, as Turner was making the anvil ring with the ponderous strokes of his hammer, two retainers from the castle entered the shed, and delivered an order from De Boteler for his immediate attendance. Wat laid the hammer on the anvil, and, passing the back of his right hand across his forehead, to clear away the large drops that stood there, looked with a kind of smile at the men as he said, HoME泷泽萝拉四部和集下载
