Definitions

  • the proposed invention refers to a method or mechanism for the formation of spiral wire shape, which upwinds in space forming a solenoid (Fig . 3) , which is characterised by the use of a modif ed, automatic, two-dimensional wire bending machine for the formation of each spiral coil and by the use of holding mechanism for the created solenoid, which mechanism is in coordination with the bending mechanism for the upwinding of the coils and the formation of a solenoid spiral body, where the proposed method has the capability of creating unpwinding spiral shapes with uniform or different shape for each coil (Fig. 3) .
  • a plane wire frame is done in the, automatic or not , bending machine by stepwise advancements of the wire for particular lengths I v and subsequent bending actions at angles ⁇ v .
  • This is explained in Fig . 1 (a) , where the wire ( 1 ) , coming from a reel is pulled by the automatic bending machine (3 ) through the pulling/ straightening devices ( 4 ) , (5) and at point O it is bent right (or left ) by the bender (6 ) .
  • the lengths (l v ) are measured from point O on the OX' axis , with left/positive the clockwise direction and left/negative the counter clockwise direction .
  • a plane wire is shown as an example, and it was created as follows : Advancement : l , Bending: ⁇ j , Advancement : I2, Bending: q>2 r Advancement : l j , Bending: ⁇ j . If the advancements ( lv ) and bendings ( ⁇ v) of the wire are continued , then with the aid of the small inclined plane ( 7 ) [Fig - 1 (b) ] , the created wire form is occupying a second level , above the previous plane form which is seated on the upper surface (8 ) of the bending machine (3 ) . This way, a wire shape can be created which is formed of many levels one on top of each other, having a distance between each other equal to the wire thickness .
  • the present invention consists of the development of a special machine, which can be combined with an existing automatic, bending machine, in order to create a mechanism for the production of multilevel wire products .
  • the present invention utilises an automatic, two- dimensional wire-bending machine for the production of each coil .
  • This machine is modified in order to obtain the working plane to be horizontal and facing downwards , so that the created wire product is "hanging" downwards due to gravitational force (Fig. 2 ) .
  • a "table” [Fig. 2 , ( 10 ) ] is placed exactly below the working plane and the created coils are seated on it .
  • the table has the arms ( 11 ) for the protection of the created forms against buckling or twisting .
  • the table ' s downward motion is coordinated with the straightening and bending motions of the wire, in order to prevent bending and twisting of the wire anywhere, due to lack of synchronisation between the coil motion and the existing formation (Fig. 2 ) .
  • the use of a holding table under the bender has the purpose of holding the formation and also allows for the transportation of the product to a permanent storage compartment or to a production line . Therefore, the holding table constitutes a means for automating the production process .
  • a first invention embodiment is shown in Fig. 2.
  • the bending machine (3) is placed in such a way that the horizontal surface (8) is facing downwards and not upwards (as it is common practic ) and the product (9) is practically hanging from the bender (6).
  • (10) consists of a square or circular upper surface and it is connected with the arms (11) in such a way so that it can slide moving vertically upwards or downwards , while the arms
  • the hanging table (10) and the arms (11) make the appropriate movements.
  • the movements of the hanging table (10) and the arms (11), connected with the table, may be understood by the following remarks:
  • the hanging table move in a direction parallel to the axis OX' (or OX) and remain parallel to itself during the l v advancement of the wire. Also the table movement is of the same speed as the wire movement advancing (Fig. 2).
  • the table turns around a vertical axis passing from the center O of the bender during the rotation at an angle ⁇ v , of the side l v , simultaneously , with the same angle ⁇ v and having the same angular speed.
  • FIG. 2 One (among many) engineering way for achieving above movements , is shown in Fig. 2 wherein the hanging table (10) turns by rotation of the arms (11) which are supported through the ball bearings (12) on the fixed body (13), driven by the servomotor (15). Moreover, the table (10), based on the fixed body (13), participates to the latter' s (13) movement along the axis O'Y driven by the servomotor (16) and the chain (17), and by its sliding on the axes (18) of the fixed body (18). Finally, the table (10), based on the fixed body (13), participates to the latter' s (13) movement along the axis O'Y driven by the servomotor (16) and the chain (17), and by its sliding on the axes (18) of the fixed body (18). Finally, the table (10), based on the fixed body (13), participates to the latter' s (13) movement along the axis O'Y driven by the servomotor (16) and the chain (17), and by its sliding on the axes

  • the table (10) is based on the screw (22), which can rotate driven by the servomotor (24) through the sprockets and the chain (23). Thus, the descent of the hanging table (10) is adjusted , in combination to its rotation driven by the servomotor (14), in order to have adequate space for placing the product being continuously produced.
  • the screw (22) is supported by the ball bearings (25) on the fixed body (13). It is noted that the fixed body (13) may be supported sliding on an arm rotating around O' moving on the plane YO'X, therefore we may also use for K, "a polar coordinate system" instead of "the cartesian coordinate system" already described .

Abstract

L'invention se rapporte à un procédé et à un mécanisme de production de fil de la forme d'un solénoïde à enroulement en spirale (Fig. 3), qui se caractérisent par l'utilisation d'une machine à plier le fil, automatique, modifiée, de façon à ce que le plan de production de la forme du fil soit horizontal et se présente face vers le bas (Fig. 1), et par l'utilisation d'un méchanisme inférieur pour le maintien du solénoïde créé, venant de la table de maintien [Fig. 2(10)] comprenant des bras (11) destinés à protéger le produit des déformations lors du processus de production, alors que le déplacement de la table est synchronisé avec l'avance et les mouvements de pliage de la machine à plier automatique.
