A method for finishing post-welding surfaces by moving the cutting tool along the weld; in this method the weld face allowance is removed in one step during a single pass of the cutting tool, which is equipped on one side with linearly arranged teeth, with the height of the cutting edge of successive teeth changing and increasing according to the direction of feed, and the difference in edge height between the first and last tooth being equal to the height of the cover pass allowance; the number of teeth is determined by the length of the weld, and the tooth length being at least half the distance between successive teeth. The subject of the invention is also a multi-edge tool for finishing welding surfaces, made in the form of a steel bar with a rectangular cross-section provided on one of the outer surfaces with tooth-shaped cutting elements, in which the width of tooth is equal to the maximum width of the allowance on the face, the length (g) of the tooth is at least half the distance (P) between teeth, and the difference in the height of the edges between the first tooth and the last tooth is equal to the height of the allowance that is to be removed, with the teeth arranged linearly and their number depending on the length of the welded joint.

Provided is a wire rod for an I-type oil ring, which includes right and left rail portions and a web portion connecting the rail portions, which has an oil hole or a molten through hole formed in the web portion, and which has a circumscribing circle diameter of 10 mm or less in its transverse contour. The molten through hole has such a remolten portion formed on its exit side as encloses the exit of the molten through hole. The remolten portion exceeds such a molten portion in the transverse section along the center of the molten through hole as is formed in the molten through hole, and is formed to have 200 µm or less from the outer circumference of the molten through hole and 100 µm or less in the depth direction of the molten through hole.

An extraction system is designed for metal working and other applications. The system may comprise a blower that delivers a positive pressure airflow to a hood that creates an air region for removal of airborne components from a work area. Return air is filtered in a filter region, and debris removed may be separated by a baffle in the filter region to limit re-uptake of the debris by the blower during operation of the system.
摘要:
Die Erfindung betrifft eine Rohrdurchführung für Rohrinnenentgratungs-Systeme zur Verbindung mit einem Impeder (1) und/oder einer zusätzlichen Verlängerungsstange in Verbindung mit dem Einsatz eines Innennahthobels, bestehend aus einem Grundkörper Rohrdurchführung (2), einem mit dem Grundkörper Rohrdurchführung (2) verbundenen Steg (3), einem mit dem Steg (3) verbundenen Aufnahmerohr (4), einer in dem Aufnahmerohr (4) befestigten Kupplung Rohrdurchführung (5) und mehreren in der Rohrdurchführung verlaufenden Medienleitungen (24). Die Erfindung schlägt nun vor, dass das Aufnahmerohr (4) an seiner Innenumfangsfläche einen Innensechskant (26) aufweist und die Kupplung Rohrdurchführung (5) an ihrer Außenumfangsfläche einen zu dem Innensechskant (26) des Aufnahmerohres (4) passenden Außensechskant (22). Weiterhin weist die Kupplung Rohrdurchführung (5) an ihrem dem Impeder (1) abgewandten Ende ein Außengewinde (25) an ihrer Außenumfangsfläche auf und ist mittels einem auf das Außengewinde (25) aufgeschraubten Konterkegel (30) in dem Aufnahmerohr (4) befestigt. Des Weiteren umfasst die Erfindung eine Baugruppe bestehend aus einer erfindungsgemäßen Rohrdurchführung und einer als Drehsegment ausgebildeten Aufhängung (31). Diese ist dazu geeignet, die Rohrdurchführung zu halten, wobei an der Rohrdurchführung eine Kupplung (7) vorgesehen ist, die eine Anlagefläche (32) aufweist, während an der Aufhängung eine Gegenanlagefläche (33) vorgesehen ist. Die Anlagefläche (32) und die Gegenanlagefläche (33) sind miteinander in Wirkverbindung bringbar ( Fig. 1 ).
