| 161 | Manufacture of box nut | JP15886286 | 1986-07-08 | JPS6316827A | 1988-01-23 | SATO YOSHIHARU |
| PURPOSE:To obtain a box nut whose thread ridge has been provided to the deepest part of the inner wall, by one process, by rotating and inserting a rolling roller which has the same effective diameter as the inside diameter of a screw hole and can execute thread rolling, to the bottom part of the screw hole, with respect to a box nut which has a screw hole of a prescribed diameter and whose thread is unworked. CONSTITUTION:With respect to a box nut original die 3 of a zinc alloy, a rolling roller 4 is rotated and inserted vertically into a bottom part 5 of the box nut original die 3. In this case, an internal screw hole of the box nut original die 3 coincides with an effective diameter of a male screw to be screwed. The rolling roller 4 rotates to the right and the left, in case of a right thread box nut, and in case of a left thread box nut, respectively. As for the rolling roller, a thread is cut to its tip in order to provide a thread ridge to the deepest part of the inner wall of the box nut original die, and that which can execute rolling is required. After the rolling has been ended, the rolling roller 4 is rotated in reverse and drawn out. | ||||||

| PURPOSE:To obtain a rolling die capable of rolling an internal thread by setting a nearly cylindrical roller die forming a rolling projection on an outer peripheral surface autorotatably to project a part of the periphery of each roller die slightly from a periphery of a turning main spindle. CONSTITUTION:The top end side of rotative shaft 1 equipped orthogonally to fitting base plate 2 is formed into a large diameter cylindrical form to form a main spindle 3 for turning die. On the other side, the roller dies 4, 4, 4 formed rolling projections 5, 5 - by cutting a continuous wavy groove on the periphery of the nearly cylindrical shape in the radial direction is prepared. Then, the dies 4 are attached pivotally and freely turnably on the trisected positions of the periphery of spindle 3, a part of periphery of each die 4 is slightly projected from the periphery of spindle 3 and fitted loosely to turn with the shaft 6 as a center. The base plate 2 of this die is fixed on a shaft of drilling machine, for example, while rotating, by inserting each die into a preparatory hole B of a material A to be worked, the internal thread rolling is performed in the hole B. | ||||||

| PURPOSE:To enhance light-resistance of a magneta dye image and to improve the color balance among the magenta and the other dye images in the course of color fading, by forming a non-photosensitive layer contg. no UV absorber on the uppermost non-photosensitive layer contg. the UV absorber. CONSTITUTION:The magenta coupler to be used is at least one of 3-anilino-5- pyrazolone type coupler represented by the shown formula. At least 2 non-photosensitive layer made of a hydrophilic binder contg. a UV absorber are formed on a layer located farther than a magneta-contg. layer from a support. It is desirable that the UV absorber is a benzotriazole compound. A non-photosensitive layer contg. no UV absorber, and consisting substantially of a binder component is formed on the reverse side of the support as the uppermost layer. The presence of this layer enhances light fastness of the magenta dye image to an extremely high grade. | ||||||

| The internal thread-rolling tool employs evenly spaced rim rollers which turn round their axes relative to the revolving body through an angle equal to the thread lead angle. The body also contains grooving rollers (6,7,8) cutting at the same angle as the thread rollers (3,4,5) and with the same spatial relation to the axis round which the body rotates (1), but turned at an angle to the thread rollers. - The thread vertices of the grooving roller are axially offset from those of the directly preceding thread forming roller as projected onto a plane normal to the body axis by an amount P/2-P.Beta/360 deg., where P is the thread pitch being generated and BETA is the angle between the rotation axes of the grooving and preceding thread forming roller projected onto the plane specified. Thus the grooving rollers enter the blank first and act as cams guiding the vertices of the thread forming rollers following on behind.(1,2) | ||||||

| The invention relates to a method for producing threads, especially internal screw threads (34), by means of a rotationally driven thread former (10) which drive the pitches of the screw thread outwardly in a non-cutting manner by pressure forming in and on the surface of the workpiece. The aim of the invention is to produce threads with various nominal diameters in a particularly economical manner and with improved structural quality. In order to achieve this, a shank tool (10) is fitted with profile projections which are arranged at a constant distance in relation to each other according to the type of thread milling cutter. Said profile projections (20) are formed in a continuous manner and have a variable radial extension on the periphery of the head of the thread (18), and are initially inserted into the tool at a point on the periphery (SU) of the workpiece bore in the workpiece. Said workpiece is arranged, preferably, at the full thread depth (TG), and a relative circular movement of 360° in relation to the axis (30) of the workpiece bore (16) is carried out maintaining the eccentricity (EX) of the rotational axis adjusted by the axis (30) of the workpiece bore (16), while the head of the thread also carries out a constant axial relative forward displacement movement (BV) corresponding to the thread pitch (P) which is to be produced. | ||||||
