Definitions

  • the invention relates to hardware, namely to fasteners intended for joining parts [F16B 23/00, F16B 23/00].
  • the closest analogue is a SELF-TAPING SCREW [patent CN201461667, publ.: 07.29.2015], which includes a rod pointed on one side, an external triangular thread is made along the length of the rod, a countersunk head is made on the other side of the rod, the surface of which is symmetrical with respect to the central axis of the head cruciform slot.
  • the technical result of the invention is to ensure the preservation of the shape of the slot when using (screwing or unscrewing) the fastener, eliminating the effect of slipping the tool from the slot of the fastener when using it, increasing the speed of installation of the fastener.
  • the technical result of the invention is achieved due to the fact that the claimed method of manufacturing a head of a fastener, characterized by cutting along the length of the external thread rod, performing on one side of the head rod, on the surface of which a slot is extruded into the depth, characterized in that they form a slot head in cross section so that it has an inverted T-shaped the shape or slot on the surface of the head is made in the form of a star with an even number of rays, the center of which lies on the longitudinal axis of the rod, while adjacent rays have a multidirectional bevel of the slot of the relative surface of the head.
  • Figure 1 presents a General view of the fastener.
  • Figure 2 presents a top view of the head of the fastener with a slot of a T-shaped.
  • Fig.3 shows a top view of the head of the fastener with a slot in the form of a six-pointed star.
  • the fastener comprises a pointed rod 1 (see FIG. 1), a thread is made along its length, a head 2 is made on one side of the rod 1.
  • a slot 3 is made on the surface of the head 2, the cross-section of which in the transverse plane represents an inverted T-shape (see Figure 2).
  • the fastener on the surface of the head 2 has a slot 4 in the form of a six-pointed star, the rays of which are inclined relative to the surface of the head 2 (see Fig. C) so that the angle of inclination of the three rays of the star located relative to each other at an angle of 120 degrees is made in one direction of the rotational motion, and the angle of inclination of the other three rays is made in the opposite direction of the rotational motion.
  • the fastener is used as follows. To connect the parts, the fastener with a pointed end is substituted to the surface of one of the parts to be joined, after which a tool for twisting the fastener (not shown in the figures) is inserted into the slot 3.
  • the working surface of the tool for twisting the fastener according to the first embodiment of the invention can be made in the form of a L-shaped profile, the length of which corresponds to the length of the slot 3, and the cross section is made slightly smaller than half of the T-shaped slot 3.
  • the tool is rotated 180 degrees along its axis, inserted into the slot 3 of the fastener, and by giving it a rotational movement, the fastener is twisted.
  • the working surface of the tool is also securely held in the slot 3.
  • different tools are used for screwing in and out, the working parts of which are made in the form of three-pointed stars, while the end of the working part of one tool has a bevel to the left, and the end of the working part of the second tool has a bevel to the right, while for screwing in use the tool with the tilt of the working part to the left, and for twisting - with the tilt of the working part to the right.
  • Ensuring the shape of the slot, eliminating the effect of slipping the tool from the slot of the fastener is achieved by making the slot 3 in the head 2 in the form of an inverted T-shape to ensure reliable retention of the working part of the tool, which also prevents premature wear of the slot 3, or is achieved due to the fact that the slot 4 on the surface of the head 2 is made in the form of a star with an even number of rays, the center of which lies on the longitudinal axis of the rod, while adjacent rays have a multidirectional bevel of the slot 4 nogo head surface that provides when screwing or unscrewing the pressing of the working part of the tool to the bottom of the recess 4.
  • Eliminating the effect of slipping the working tool allows you to increase the speed of twisting and installation of the fastener.

Abstract

L'invention concerne des articles métalliques de fixation, notamment des moyens d'assemblage destinés à assembler les éléments [F16B 23/00, F16B 23/00]. Le résultat technique consiste en la possibilité d'assurer la forme d'une cannelure lors de l'utilisation (vissage ou dévissage) de l'accessoire de fixation, éliminer l'effet de glissement de l'outil de la cannelure lors de son utilisation, augmenter la vitesse de montage de l'accessoire de fixation, ce qui est obtenu grâce au fait que le procédé de fabrication de l'accessoire de fixation est caractérisé par la réalisation d'un filet sur la longueur de la tige, la réalisation d'une tête à la surface de la tige à l'une des surfaces de laquelle on crée la cannelure, qui se distingue en ce que l'on forme la tête de la cannelure dans la direction transversale de sorte qu'elle ait une forme en T inverse, ou alors la cannelure à la surface est réalisée sous la forme d'une étoile à nombre pair de branches dont le centre se situe sur l'axe longitudinal de la tige, et les branches voisines présentent des directions différentes de la partie chanfreinée de la cannelure par rapport à la surface de la tête.
