    摘要： A tool for making joints between sheet-formed members (4, 5) comprising a first tool-part (1, 2, 3) with a punch (1) and a side pressing element (2) and a second tool-part (6, 11) provided with a support surface (9) from which an anvil (8) erects, a matrix (6') comprising at least two matrix-parts (6) each having an upper active matrix surface (13) and being arranged around said anvil (8). Each matrix part comprises a portion (14) arranged sliding against said support surface (9) and being applied against the lateral surface of said anvil (8) by means of elastic means (7). Retention means (10) are arranged limiting the longitudinal movement of the matrix parts during the retraction of the punch (1). The upper active matrix surface (13), the portion (14) arranged sliding against said support surface (9) and said retention means (10) are arranged in that order from the top of the second tool-part (6, 11).

    摘要： Method and apparatus for carrying out an operation, such as pressing, riveting, cutting etc., on a mechanical workpiece which operation comprises at least one stroke, or movement, along a predetermined path, of at least two active members (6, 7) each being arranged on a carrying unit (1, 2). The mechanical workpiece is first positioned between the active members (6,7). Thereafter the carrying units (1, 2) for the active members are approached to each other in a first part of said stroke. The carrying units (1, 2) are then locked to each other at the end of said first part of said stroke and a second part of said stroke is carried out by means of the relative movement between the active members (6, 7) to achieve the desired effect on the said workpiece.

    摘要： Procédé et appareil de réalisation, sur une pièce à usiner, d'une opération telle que le pressage, le rivetage, le découpage ou analogue, dans laquelle au moins deux éléments actifs (6, 7), dont chacun est monté sur une unité porteuse (1, 2), effectuent au moins une course ou au moins un mouvement en suivant un trajet prédéterminé. Dans un premier temps, on place la pièce mécanique entre les éléments actifs (6, 7), puis on rapproche l'une de l'autre les unités porteuses (1, 2) dans une première partie de ladite course. Ensuite, on rend solidaires l'une de l'autre lesdites unités porteuses (1, 2) à la fin de ladite première partie de ladite course, et une seconde partie de ladite course est réalisée par un déplacement des éléments actifs (6, 7) l'un par rapport à l'autre de manière à avoir l'effet voulu sur ladite pièce à usiner.

    摘要： Apparatus for carrying out an operation on a mechanical workpiece which operation comprises at least one stroke, or relative movement, along a predetermined path, of at least two tool members (4, 5) each being arranged on a tool carrying member (1, 2). The mechanical workpiece is positioned between the tool members (4, 5) and the tool carrying members (1, 2) are approached to each other in a first part of said at least one stroke. At least one force transferring element is arranged to be inserted by means of a low force during said first part of said stroke into a position between at least one tool carrying member and an activation element for transferring a high force during a second part of said stroke between said activation element and said at least one tool carrying member.

    摘要： Method for joining together two or several overlying sheet formed members (1, 2), at which an essentially coaxial arrangement of a punch (4), a die (3), with a die cavity (9), and an anvil (5) are caused to cooperate by means of their coaxial relative movements, comprising the following steps: (a) said overlaying sheet formed members (1, 2) are placed between the punch (4) and the die (3); (b) said punch (4) is caused to carry out a first relative movement in a first direction coaxially towards said die (3); (c) an essentially cylindrical core portion (6) of the punch (4) is caused to coact with the die cavity (9) to form during the movement in the direction of the die cavity (9) by means of drawing of said sheet formed members (1, 2), a cup-shaped or protruding portion (10) having a side wall portion and a bottom wall portion (12); (d) said anvil (5) is caused to carry out a movement relative to said die in a second direction and is caused to be locked in a predetermined position relative to the die; (e) said punch (4) is caused to carry out a second relative movement in said first direction coaxially towards said die (3), and by means of forces between said punch (4) and said anvil (5) compress said bottom wall portion whereby there is formed a laterally enlarged shape which mechanically interlocks the sheet formed members (1, 2) and whereby said punch is provided, around the rear end of said core portion (6), with a lateral extension (8) which during said step c is caused to deform and displace material from the area around the opening (11) of the cup-shaped or protruding portion (10) mainly in the upper sheet formed member (1) axially in the direction of the die (3).
