Abstract:
A punch (1) for inserting tubular connectors (14) into plastic pipe (6) where there is a long shaft (9) that can project fully through the connector bore (13) and having sharp conical end pierce (11) directly the wall (12) of the tubular pipe (6). There is also disclosed a punch (14) with an automatic supply of tubular connectors (42).
Abstract:
A method of producing a bevel gear, particularly a bevel ring gear, the bevel gear comprising mounting surfaces. The method comprising the steps of flashless warm forging a blank, preferably an annular blank, in a forging die to produce the bevel gear with precision forged teeth; performing a hardening operation on the teeth; and then, without machining, finishing the teeth by lapping the teeth with a mating bevel gear. A die apparatus for use in a press for forging the bevel ring gear from the annular blank is also disclosed.
Abstract:
A method of rollforming one-piece tubular doorbeams (10). The method includes the steps of drawing a continuous metal strip (20), creating cut-outs (22) in the edges of the strip at spaced locations, rollforming the strip into a tube (30) so that the unindented edges (24) engage one another, welding the engaged edges together, cutting the tube in the areas of the cut-outs (22, 32) to create pre-forms (40), and opening the ends of the pre-forms to create end brackets (16). Additional optional steps provide customization of the end brackets.
Abstract:
A metal article of manufacture including a tubular body portion (102) and free-formed metal features (104) on the tubular body portion (102). The free-formed metal features are formed of a layerwise deposition of a molten metal material in a predefined pattern to form the desired free-formed feature (104) or construction.

Abstract:
The invention relates to a method for producing laminated cores consisting of sheet parts. According to said method, the sheet parts are arranged next to each other and joined to each other to form a laminated core (1). Substantially arc-shaped sheet part segments (2) with a peripheral length corresponding to an angle alpha = 360 DEG /n, n being a whole positive number and greater than or equal to two, are produced by stamping. n of these sheet part segments (2) are then arranged in one plane to produce a sheet part, the sheet parts arranged next to each other being connected and/or welded with at least one connecting element (3).
Abstract:
The present invention provides a method and apparatus for forming a plurality of parts, such as spade type boring bits (410), from a continuous stock material (12). Thus, the various steps of the forming method of the present invention can be performed to predetermined portions of the continuous stock material (12), prior to separating the continuous stock material (12) into a number of discrete parts. The efficiency of the forming process is enhanced since individual parts need not be individually transported and oriented during the forming operations.
