Patent number: 5842267Abstract: The present invention provides a method and apparatus for forming a plurality of parts, such as spade-type boring bits, from a continuous stock material. Thus, the various steps of the forming method of the present invention can be performed to predetermined portions of the continuous stock material, prior to separating the continuous stock material 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. By not requiring that the individual parts be separately transported and oriented during the forming operations, the quality of the parts formed by the forming method and apparatus of the present invention will also be enhanced since such separate transportation and orientation of individual parts generally increases the opportunities for misalignment and contributes to poor tolerance control during the manufacturing process.Type: GrantFiled: June 14, 1996Date of Patent: December 1, 1998Assignee: Black & Decker, Inc.Inventors: Ronald R.

Patent number: 5341667Abstract: A container is formed with a bottom wall comprising a central panel and a resting radius formed from an annular wall depending downwardly from the central panel periphery and then outwardly and upwardly to join the container side wall. A method is disclosed which reduces the resting radius by tightening the curvature thereof through deformation of the outer annular wall so that the resting radius is better able to resist eversion under the influence of pressure within the container. The outer wall is deformed by radially inward flexing of plural fingers which are cammed radially inwardly into contact with it through a cam follower arrangement which also controls a can support member to (1) locate the bottom wall in a first position between the reforming fingers and supporting anvil, and (2) in a second, elevated stripping position where the container is removed from the apparatus. The container bottom wall is preferably reformed during necking-in of the container open end.Type: GrantFiled: May 1, 1992Date of Patent: August 30, 1994Assignee: Reynolds Metals CompanyInventor: Harry W.

Patent number: 5335530Abstract: The pressing tool (10) comprises two holding members (26,28) adapted to be moved towards each other and having press dies (44,46) displaceably arranged thereon. Adjacent press dies (44,46) are oriented at a right angle to each other, with two press dies (44) being supported on one holding member (26) and two further press dies (46) being supported on the other holding member (28). The press dies (44,46) of both holding members (26,28) can be displaced along an axis extending at an angle of about 45.degree. to the moving direction of at least one of the two holding members (26,28). Prior to the pressing process, the press dies (44,46) are spaced from each other, and during the pressing process, while the holding members (26,28) approach each other, the press dies (44,46) move towards each other until reaching their final closing position.Type: GrantFiled: September 9, 1992Date of Patent: August 9, 1994Assignee: Hewing GmbHInventor: Karl G.

Patent number: 5297417Abstract: A portable, self-contained collet crimping apparatus includes a base having a hand-actuated hydraulic pump assembly mounted thereon is disclosed. A collet crimping machine is pivotably mounted on the base so as to be adjustably oriented at any desired angle. Means are provided for selectively retaining the collet crimping machine in a desired rotational position relative to the base. The hydraulic pump assembly is connected to actuate the collet crimping machine. The collet crimping machine further includes a pusher which secured to the machine to prevent loss, yet which is slidable between extended and retracted positions. In the extended position, the pusher is disposed outwardly away from the collet crimping machine to permit easy replacement of a die assembly. In the retracted position, the pusher is disposed within the collet crimping machine and precisely aligned with the other components thereof for use.Type: GrantFiled: September 18, 1992Date of Patent: March 29, 1994Assignee: Dana CorporationInventors: Eric D.

Patent number: 5293769Abstract: A forging machine has four forging rams (2) supported by the machine frame (1) for movement radially towards and away from the system axis (5) in an X arrangement at 90.degree. to one another. Piston and cylinder units (12-15) on the machine frame each have a ram (2) as a constituent part and have a stroke corresponding to the working stroke of the ram. A crosshead (16) supports each piston and cylinder unit, and is adjustable (23-25) relative to the machine frame for setting the stroke position of the ram. An adjustable die holder (6) at the radially inner end of each ram adjusts a die (5) thereon in a direction transverse to the radial direction of the ram, so that the dies can be positioned with parts of their working surfaces overlapping side surfaces of adjacent dies to form a closed forging pass contour smaller than the working surfaces of the dies. Radially extending drive shafts (58) external to the rams and gear units (54-59) at the radially inner ends of the shafts adjust the die holders.Type: GrantFiled: December 30, 1992Date of Patent: March 15, 1994Assignee: SMS Hasenclever GmbHInventor: Peter Schubert
