The invention relates to a method for producing a composite fibre component with an integrated screw-in insert, comprising at least the following steps: a pressing tool (70) is provided, said pressing tool comprising a first tool part (71) and a second tool part (72) that can be moved in relation to the first tool part, said parts forming a cavity (74) for receiving and forming a fibre preform (80), when the pressing tool is closed; a screw-in insert (10, 20, 30) is connected to a screw device (73) integrated into the first tool part; the fibre preform is arranged between the first and the second tool parts; the pressing tool is at least partially closed; the screw device is actuated in order to screw the screw-in insert into the fibre preform; and the fibre preform is cured. The invention also relates to a screw-in insert and a pressing tool for implementing the method.

The present invention provides a self-drilling drywall anchor having a screw drive 16 that comprises a clutch configured to limit an amount of torque transmitted to the shank 5 by a tool engaged with the screw drive 16. In this way, a user may drive the anchor into a drywall, but over-tightening is prevented as the clutch limits the amount of torque transmitted to the shank 5, thereby preventing the external threads 7 on the shank from gouging out drywall material adjacent to the anchor and reducing the anchor's security within the drywall. Such gouging causes a cavity to form around the anchor, reducing its security within the wall.

Ein Befestigungselement (21) für harte Untergründe (11) weist einen zylinderförmigen Grundkörper (22) auf, an dessen Aussenseite (26) ein selbstschneidendes Gewinde (27) vorgesehen ist und der ein erstes Ende (24) mit einem Bodenabschnitt (23) sowie ein zweites, dem ersten Ende (24) abgewandtes Ende (25) aufweist. Der Grundkörper (22) weist ein innenliegendes Angriffsmittel (28) für ein Setzwerkzeug auf, das als durchgängige Öffnung (31) im Bodenabschnitt (23) ausgebildet ist. Weiter weist der Grundkörper (22) eine zum zweiten Ende (25) offene Aufnahme (29) auf, die mit einem Lastangriffsmittel (30) versehen ist, wobei sich die Aufnahme (29) in Richtung des zweiten Endes (25) an das Angriffsmittel (28) anschliesst.

There is provided an insert nut, wherein a dies is pressed on one surface of a predetermined metal plate 7 to form a screw portion 8, so as to form a patterned portion 9 on the other surface of the metal plate by forming the screw portion, wherein the metal plate 7 is wound such that the screw portion 8 to become a female screw 2 is located inside so as to form a cylindrical form, and then the opposite edges 7a, 7b of the wound metal plate are connected together to form a cylindrical shank portion 3, wherein the outside surface of the exposed patterned portion of the shank 3 is covered with a resin layer 6 such that projections 5 of a synthesis resin is formed at the outside thereof.

The present invention relates to fasteners and in particular to fasteners, such as threaded inserts, arranged in use to be self-threaded into a parent material of a workpiece. A threaded insert may fail due to a number of mechanisms, including I) due to rotation caused by the threaded insert being partially jacked out and compressing the parent material if the material of the parent material is weaker than the material of the threaded insert thereby destroying the joint or ii) by rotation where the thread formed by the threaded insert as it is inserted in the parent material becomes stripped and the threaded insert then continues to turn. A fastener (2,3) is disclosed comprising a generally cylindrical body (10,11) about which is formed a thread (16,17), the fastener having a first end and a second end, in which a first end of the fastener is provided with a knurled surface (20,21). This has the advantage that an insert having improved torque performance is provided.
摘要:
A threadedly engageable coupling device (5) is used with a complementary coupling device (6) for tightening first and second article pieces (71, 72), and includes an abutment head (9), a cylindrical shank (8) extending from the head (9), and a plurality of blade portions (7) disposed on a proximate segment (82) of the shank (8) proximate to the head (9). Each of blade portions (7) has a cutting edge which gradually deviates from the proximate segment (82) when extending towards the head (9) such that when the shank (8) is inserted into a bore (73) in the first article piece (7) to permit the head (9) to abut against the piece (71) by a friction force generated through screw movement of a threaded surface (811) of a distal segment (81) of the shank (8) and a threaded surface (611) of the complementary coupling device (6), the cutting edge incrementally incises the first article piece (71) so as to guard against rotation of the shank (8) relative to the piece (71) to thereby tighten the first and second article pieces (71,72) together.
