| 62 | METHOD OF PRODUCING A ROTATIONALLY ORIENTED THREAD | PCT/EP2014075094 | 2014-11-20 | WO2015075109A2 | 2015-05-28 | ONLEY BEN; YEOMAN STEPHEN |
| A method of producing a rotationally orientated thread starting at a desired angular position and suitable for mass production is provided. The method is particularly suitable for improving the angular positioning of spark plugs in car engines. The method involves measuring precisely the length of the tool and the distance, at a particular angular position, of a full thread form of the thread to the tip, so that its start position at the tip can be calculated. Using that distance as an offset of the length of the tool reported to the CNC machine, and starting from its reference position, it commences producing the thread in the bore at the desired angular position of the bore. | ||||||

| A method for producing a thread in a workpiece comprises the following process steps: a) producing a wall of the workpiece, wherein the wall has a number n of grooves greater than or equal to 1 encompassing a thread axis, b) introducing a corresponding thread-producing region of a thread-producing tool into each of the grooves, c) producing a thread in each subregion, adjoining the groove(s) of the wall of the workpiece by rotating the thread-producing tool about the thread axis, wherein, following rotation, each thread-producing region projects into the same groove again or into another groove in the wall, and d) moving each thread-producing region of the thread-producing tool out of the associated groove in the direction along the groove. | ||||||

| 68 | Method and arrangement for gaging a thread produced in at least two working steps | US11764717 | 2007-06-18 | US07536795B2 | 2009-05-26 | Helmut Glimpel; Dietmar Hechtle |
| A method for gaging a thread can include gaging at least one preliminary thread using a preliminary gage (e.g., a preliminary go gage, and/or a preliminary no go gage). The preliminary thread can be produced in a first step by removing material from the workpiece. The at least one preliminary thread has a preliminary thread profile, and the preliminary thread gage is adapted to the preliminary thread profile. In addition, the method can involve gaging a final thread using a final-thread gage (e.g., a preliminary final-thread go gage and/or a final-thread no-go gage). The final thread can be formed in a second step by plastic pressing-in of the material of the workpiece at least in a section of the preliminary thread profile using at least one thread-forming profile. The final thread has a final thread profile, and the final-thread gage can be adapted to the final thread profile. | ||||||

| A method for the production of threads, especially internal threads, by means of a rotationally driven thread former, with which the thread pitches are driven in and out of the surface of the workpiece in a chipless fashion by pressure forming, in particular in and out of the inner surface of a workpiece bore. In order to be able to produce threads of different nominal diameter especially economically and with improved joining quality in the area of the thread, the thread is formed such that a shank tool in the fashion of a thread miller, equipped with at least one profile projection, preferably two profile projections located at a constant distance from one another, where the profile projections at its forming head are constructed as continuous over the circumference and with radial extension varying over the circumference, is driven into the workpiece initially at a circumferential point of the workpiece bore, preferably is brought to the total thread pressing depth, and while substantially retaining the eccentricity set with respect to the axis of the workpiece bore, executes a relative circular movement running through 360° (circular movement) relative to the axis of the tool bore, while the forming head simultaneously executes a constant axial relative feed movement by the extent of the thread pitch to be produced. | ||||||

| A hydrotapping power unit is disclosed that is operable to position and hold a hydrotapping tool in a home position adjacent a part while the part is being hydroformed in a die cavity, to then advance the tool to pierce a hole in the hydroformed part while the part remains in the die cavity and under pressure and then continue to advance the tool to inwardly extrude the part about the hole, to then further advance while also rotating the tool so that the tool is fed at a feed rate equal to the thread pitch of the tool to thereby form a thread in the pierced hole, and finally to retract while also rotating the tool but in the reverse direction and at the same feed rate to release the tool from the threaded hole. The power unit performing these operations includes a linearly moveable shaft for holding the tool, a powered device for rotating the shaft, a powered device for linearly moving the shaft, and a lead screw connection between the latter powered device and the shaft having a thread pitch equal to that of the tool. | ||||||

| The disclosure relates to a threaded bushing which, upon entering and turning in the initially smooth bore of the work piece, will form through its own male thread the corresponding internal thread within the wall of the work piece bore. The bushing is formed with one or more exterior bevels or grooves which extend axially over at least several threads and intersect such threads to form spoon or cup-shaped frontal areas where each bevel or groove merges into a respective thread. | ||||||

| 73 | Die actuator | US3710410D | 1971-09-07 | US3710410A | 1973-01-16 | ANDREASEN A |
| A die actuator for moving an operating lever of a threading die on automatic screw machines, and the like, having a turrethead indexable through a plurality of different work positions and slidable along a work axis toward and away from the workpiece. The die actuator comprises a base which is fixedly secured to the bed of the automatic screw machine and defines vertical guide means. An actuator slide is mounted for vertical sliding movement on the base in said guide means between an elevated, upper position and lower, rest position. Lift means extends outwardly of the slide into the path of travel of the operating lever on the threading die as the die moves during indexing of the turret. ENgagement between the lift means and the die operating lever during turret indexing causes the lever to close the die and move the thread chasers into position ready for cutting threads on a workpiece. When the head is subsequently moved forward toward the workpiece, the operating lever moves out from under said lift means and the actuator slide drops downwardly to the rest position out of the way of the turrethead and any of the other tools mounted thereon.

| An apparatus for repairing damaged threads on a shaft, rod or other similar member. An adjustable plate, a cutter support block and a pressure block are slideably mounted to a rod. Fasteners securely fasten the adjustable plate and the support block to the rod whereas the pressure block is loosely mounted to the rod. The support block is suspended from the adjustable plate by a wing bolt threadedly received in the adjustable plate with an end seating in the pressure block. A V-shaped pressure plate is fixedly fastened to the pressure block cradling the top of the threaded member to be repaired. A chaser having a cutting edge matched to the threads of the member to be repaired is mounted to the support block beneath the pressure plate. A thread support is mounted to the support block having an angular end abutting the member to be repaired.
