Definitions

  • This invention refers to a process for the blanking of metallic drawer guides, in particular of metallic guides for so-called “self-closing" drawers capable of ensuring a perfect closing of the drawers (see for example EP-A-0 520 539).
  • the mobile element of the drawer guides generally profiled with an essentially "Z"-shaped transversal cross section and with curved lengthwise rims in the terminal portion of the section, presents a downward sloping area near its terminal portion. More exactly, this means an area sloping downward from the base of the ramp-type "Z"-shaped section, which supports a sliding roller firmly attached to the shoulder of the furniture item housing the drawer.
  • slots are for instance carved out in the flat unfinished material of the preform, so as to allow the subsequent production of the inclined ramp or area by a profiling or bending process.
  • Such an operation causes a weakening of the guide's structure in that area, so that the guide may later fail, even if perfectly profiled.
  • the item cannot ensure the produced guide's stability in time.
  • the presence of the slot generates an area in which the guide is discontinuous and presents an opening in its lateral wall. Despite its small size, this opening may allow the entering of a foreign body and thereby cause a poor or improper functioning of the sliding roller in the drawer.
  • the general purpose of this invention is to eliminate and solve the mentioned technical problems inherent in the known blanking system for metallic drawer guides, in an extremely simple, economical and particularly practical manner.
  • Another purpose is to eliminate and utterly minimize any type of sagging of the "self-closing" type of the ramp or area sloping downward from the base of the "Z" section in the terminal portion of the roller guide, while also improving the drawer's overall looks, owing to the fact that there would be no opening to reveal the wood of the drawer itself.
  • a further purpose is to achieve a process involving a certain ease of manipulating the item "in transfer", without any significant additional labor or other plant costs for its production.
  • FIGS. 1 and 1a show a first phase of embodiment of the process of blanking the metallic drawer guides according to the invention.
  • the purpose is in fact to carry out in a transfer machine, starting from a metallic strip 10, a working process in successive phases so as to produce metallic guides for so-called “self-closing" drawers, as outlined above.
  • a first phase covers the preparation and subsequent blanking of the strip 10 by an appropriate punch 11, so as to separate a single flat preform 12, previously molded in an elongated rectangular form, capable of jointly producing the two right and left-hand opposed guides of a drawer.
  • the two opposed guides can be described as being two portions 13 and 14, separated by a central longitudinal axis 15 and eventually fitted with a row of variously distributed perforations not shown, both for the final fastening and positioning in the various phases of the subsequent processing in the transfer.
  • the flat preform 12 is in fact, in a terminal portion 12a in a lengthwise direction where an inclined ramp or area is to be produced, subjected to a coining action. More exactly, the preform 12 is, in a selected portion indicated by 16 in Figure 8 of an intermediate area 50 of the section, subjected to the action of coining or similar tools, as will be seen in detail below.
  • the tools used will be in a number of two, separated from each other, and act on two selected localized portions 16 indicated by a dashed line.
  • transversal cross section This action will cause the transversal cross section to centrally expand, by buckling and/or laterally bulging out in the terminal areas 17 and 18, while recovering some material and so to say distributing it in the most uniform possible manner over a broader cross-sectional area. In this manner, though slightly slimmer, the section will maintain its strength and resistance, even in these selected coined portions 16.
  • the bending also occurs at the terminal areas17 and 18, so that the section of the preform will generally have the shape of Figure 10a and, only in the terminal areas 17 and 18, that of Figure 10b, but in broadened and expanded form.
  • the first bending will form the two longitudinal flaps constituting the sliding seats of the drawer's rollers, not shown. These must have a constant size throughout their length, even at their terminal areas 17 and 18.
  • Figures 4, 4a and 4b show a further phase of embodiment of the process of the invention, in which a second bending occurs, in particular in a central longitudinal portion of the preform.
  • Figures 5, 5a, 5b and 5c show a subsequent phase of the process of the invention, in which the final bending occurs, in this example only along one flap indicated by 19, of the two lateral flaps 19 and 20 being part of the two longitudinal sides of the preform.
  • the preform is now profiled to its final form and contains the right and left-hand guides.
  • the two selected portions 16 where the coining operation has occurred have adexcellentously arranged themselves along the central walls of the central "Z"-shaped section with a slightly lower thickness, and do not involve any defects of strength for the single final guide in its portion shaped as an ramp or inclined area.
  • the blanking process according to the invention therefore produces two finished right and left hand guides 30 and 40 from a single preform having terminal ramps or areas 31 and 41, of a constant cross section without sudden reductions of thickness. This further eliminates the structural discontinuities caused by slots or bends of the strip.
  • This final structure of the sliding guides 30 and 40 presents an ideal strength, despite being produced from a preform of a metallic strip of an entirely normal thickness.
  • This final form is generated by the coining phase that determines an expansion of the transversal cross section, while maintaining the continuity of the section.
  • Figure 8 referred to the second phase of the transfer machine's operating process according to the invention, generally shows the possible portion of the preform 50 on which the coining operation can be undertaken.
  • Figure 9 shows an arrangement in which two coining tools or punches 26 fitted with a flat ending and appropriately separated from each other are acting on the flat preform 12, in one of its terminal areas 12a, as mentioned above.
  • a pair of ramps or inclined areas must in fact be created in this area, so as to obtain the two desired guides.
  • the two tools are applied above the preform 12, showed by a full line, deforming it in the selected portions 16 along the dashed line shown in Figure 9. This achieves an expansion of the free terminal rims 27 and/or a central buckling 28 due to a double expansion toward the center between the punches 26, determined by the two punches.
  • Figure 9a shows an arrangement in which two coining tools or punches 26, appropriately separated from each other, act on the flat preform 12 from below. The whole occurs in a manner similar to that previously shown in a terminal area 12a of the preform, where a pair of ramps or inclined areas is to be generated in order to obtain the two desired guides. The two tools are applied in a direction from below toward above against the preform 12.
  • Figure 10 exemplifies a coining action between two pairs of punches 26 and 26' having a flat terminal area, which act on the two faces of the preform from opposed sides in the selected portions 16.
  • the punches 26 and 26' act both from above and below, deforming or coining the preform which has the section of Figure 10a as shown in Figure 10b.
  • the two sections are respectively that of the preform over most of its length and the final one in its terminal area 12a, where the ramps will be applied.
  • Figure 11 shows a simple form of a coining punch 26 and 26', having a flat extremity, as shown in the previous figures.
  • This coining operation is followed by a straightening operation of one or more of the buckled and deformed areas, which have been created, before proceeding to the subsequent shaping phases of the preform.
  • the phases may be carried out successively or be interrupted by additional operations on the piece.
