Abstract:
This invention consists of an advancement mechanism which by using the motion of a revolving body (tool) transforms it into a linear advancement motion of the same object, by means of a gear wheel, of a cam, and of a latch which connects the said elements, both screwed tight and sliding, to a locating pin positioned axially to the revolving body.
Abstract:
The tool comprises expandible shoes (11) adapted for locking engagement with a pipe to be machined and mounted on a centre body (10). A head secured to said body (10) supports a rotatable tool holder plate (17) and hydraulic motors for driving and feeding said plate. A first section of a hydraulic power circuit is operated at high pressure for driving the rotatable tool holder plate (17), a second section of the hydraulic circuit being operated at low pressure for driving the expandible shoes (11).

Abstract:
Trimming tool for removing internal and external burr from the ends of tubes and comprising a sleeve, which internally is provided with a body with a conical indentation (8, 9) in one axial side of the sleeve and a corresponding conical cone-shaped boss (10, 11) by the opposite side of the sleeve, and in addition the inside body of the sleeve is divided axially in two parts, held together in operative position, between which a steel cutter (2) is mounted with a lateral surface protruding from the conical indentation (8, 9) and a lateral surface protruding from the conical boss (10, 11), whereby the body is divided along a division plan (20), which is parallel with a diameter in the sleeve, but parallel displaced in relation to corresponding diameter plane (21), and that respective body has the tip of its indentation (8, 9) respectively its boss (10, 11) situated in the middle of the dividing plane (20), whereby the conical formation is constituted by an eccentric, oblique conical indentation respectively an eccentric, oblique conical boss.
Abstract:
The invention relates to a pipe scraper for scraping the end of a plastics pipe such as a plastics gas main or water main. The device consists of a framework (10) in which is journaled a helically bladed rotary cutter (14) driven by means of a lever (17). On the shaft carrying the cutter is a pinion (16) which meshes with a larger pinion (19) driving a friction surfaced roller (21). The cutter is held in a Reed clamp and as the lever (17) is turned it rotates the helically bladed rotary cutter so as to scrape a low angle helical scrape approximating a longitudinal scrape. At the same time the rotation of the roller (21) causes the whole framework to rotate around the surface of the pipe so as to scrape the whole end peripheral surface.
Abstract:
The tool (10) includes a base (9,9a) for carrying a hollow stationary tube (7) on which is rotatably mounted a circular platform (31). A clamp (12) can securely clamp tool (10) to a work member (25) requiring a machining operation. A socket (49) is movably mounted on a cutter box (40), which is coupled to the face (33) of the platform, for linear radial movement in a direction relative to the center of the platform. The radial movement is achieved by planetary action which is controlled by a clutch mechanism (76) mounted on tube 7. Thus, the linear movement of the socket is derived from the rotary motion of the platform. In a preferred embodiment, the cutter box can pivot about the axis of a drive shaft (41) which is rotatably coupled to a planetary shaft 71. The rotation of the drive shaft is selectively translated by a clutch (53) and a transmission (45) into the radial movement of the socket, which is adapted to accept relatively inexpensive, conventional cutters (50) that can cut across the face (26) of the work member a continuous, spiral pattern.
Abstract:
Zur Bearbeitung der Schnittstelle (91) von Rohren (9), insbesondere vor dem Zusammenschweißen von Rohren den, ist eine Zentrierung, ggf. auch ein Abdrehen und Aufweiten, erforderlich. Bekannte Zentriergeräte sind so ausgebildet, daß mit ihnen die Enden zweier zusammen zuschweißender Rohre nur gleichzeitig zentriert werden kön nen. Solche Geräte sind nicht nur wegen ihrer Abmessung und ihres Gewichtes unhandlich; sie sind auch nicht brauch bar, wenn die Rohre mit axialem Versatz zusammengefügt werden sollen oder gar eine vorherige Bearbeitung der Schnittstellen erforderlich ist. Die Erfindung schafft hier Abhilfe mit einer in ein Rohrende einsetzbaren Zentriervor richtung, deren Spannsystem zugleich zu ihrer Halterung in dem Rohr dient und die eine Kupplungsvorrichtung (7) zum Ansetzen eines Zusatzgerätes, zB einer weiteren, ebenso ausgebildeten Zentriervorrichtung, einer Aufweitvorrichtung oder einer Abdrehvorrichtung, aufweist.
Abstract:
The pipe milling or cutter device comprises spindle frame (8) restrained from rotating with respect and associated to a rod (1) which is locked onto a pipe (T) being machined, the cutting tool (37) being carried on the spindle (17) with the interposition of a carriage (33) operative to provide automatic radial feed features. Thus, the cutting reaction couple generated on the spindle frame (8) is balanced without resorting to outside actions, thereby the possibility is afforded of cutting large thickness pipes.
