摘要： A kit of parts for auto body dent repair includes a plurality of tool bodies (11) and a plurality of tips (80). Each tool body includes a rearward shaft (20) and handle (60). The rearward shafts of the various tool bodies include both those with compound (bent) shafts and simple (straight) shafts. The lengths of the tool bodies varies to fit different needs. Each tool body also includes a forward shaft (40), which is adjustably attached to a forward end of the rearward shaft. The appropriate tip may be installed on the forward end of the forward shaft of the appropriate tool body. As an alternative to the tips (80) and forward shafts (40), an integral dent repair tip (50) provides the functionality of a both in a single unit. In use, the appropriate tip (80), or integral dent repair tip (50), for the job may be installed on the appropriate tool body. The overall tool is then used to remove the dent from an auto body panel by applying force correctly to the inside surface of the body panel.

摘要： A device for forming components from billets having a thickness profile which is essentially symmetric to the central plane of the billet, i.e., the billet contains a thickness transition on both sides, and wherein the thickness transitions on both sided of the billet are transferred to one side of the formed such that the side of the formed component is planar. The forming surface of the forming device which faces the side of the billet that has a thickness transition in the formed state of the billet has a shape is adapted to the thickness transition to be realized, and the forming surface of the forming device which faces the side of the billet that becomes planar in the formed state is planar. Due to these measures, it is possible to transfer the thickness transition that originally existed on both sides of the billet to one side of the billet in only one step.

摘要： The invention relates to a forging apparatus used for forging a heated blank (24a), which in a pre-treated operation has been given a volume essentially corresponding to that of the final product, said forging apparatus comprising upper and lower die parts (2, 16) arranged to be brought together into abutting relationship and having contacting surfaces (42a, 18b) extending transversely of the direction of movement of the die parts, whereby when the contacting surfaces (42a, 18b) are pressed together and brought into contact with one another as result of pressure exerted thereon, the blank is shaped in conformity with a die cavity defined with precision by the die parts (2, 16). The configuration of the forged component then essentially agrees with that of the desired finished component, i.e. no or at least only minimum post-treatment is required. Said contacting surfaces (42a, 18b) extending transversely of the direction of movement of the die parts are arranged to have no contact with the die cavity (25) during the forging operation.

摘要： The present invention is for a method of fastening a tool holder. The tool (2) has a front side (6) shaped for use in cold forming of metal wire into nails, screws, etc. The tool holder (4) has a recess (8) shaped for receiving the tool (2). When the tool (2) is fastened in the tool holder (4), compressive stresses are initially present in the tool (2). The tool (2) is subjected to tensile stresses caused by the nail making process when in the tool holder (4). In order to reduce the resulting tensile stresses, the two opposite and wedge-shaped sides (10, 12) of the tool (2) are compressed against corresponding sides (14, 16) in the recess (8) by applying and maintaining pressure on the back side (18) of the tool with fastening means (20).

摘要： The screw has two or three non-circular super-imposed recesses. The depth of each recess is less than 1.2 mm and there is a less than 1° of draw in each recess. The screw head recess is formed using a punch (10) in a cold-heading process. The punch is formed in a profilating CNC machine, cutting the profiles (12,14,16) of the punch to a tolerance of better than ±0.025 mm. A method of manufacture of a cold-forming punch for such a screw comprises providing a profilating head as one of the tools on a turret mounted adjacent the chuck in the CNC machine. The profilating head has several cutting elements, each being adjustable with respect to one another: axially, radially and angularly.

摘要： A thread forming tap which is capable of reducing tapping torque as well as improving durability by avoiding an increase of an apparent area of margins of external thread that causes interference with a grinding stone. The thread forming tap has an external thread in a screw shape with alternately linked margins and reliefs for forming an internal thread by plastic deformation upon having the margins of the external thread bite into a surface of a prepared hole of a workpiece. A helix of the margins of the external thread is in a direction opposite to a direction of a helix of the external thread relative to an axis of the tap.
