Definitions

  • the invention relates to a sheet metal pile set for the straightening of the sheets of automobile bodies.
  • a pile is a metallic piece, generally made made of cast iron or steel, of rather bulky shape, without however preventing its manual grip, and intended to serve as an anvil.
  • heaps are commonly used for finalize the straightening of the sheets which should be taken off, including accidents. This finalization work is carried out by means of a plurality of heaps and a hammer, the heap held in one hand serving anvil for hammer strikes to achieve a smoothing of the body after its straightening.
  • the piles currently used correspond to existing patents, according to the research report US-A-1441316 and US-A-1506578, have too rounded and too heavy.
  • the pile known from document US-A-1506578 shows an elongated shape and of variable thickness and has at the thickest end a rounded edge.
  • these heaps are mainly used to straighten the sheets and little for deburring. Because on the flat surface to be taken off, for example, the use of heaps too rounded causes straightening with thinning and expansion of the metal sheet metal which is absolutely to be avoided during the debossing operation FIG.
  • FIG. 3 shows by way of illustration a vehicle body roof under which we presented a bunch of invention, the form of which follows well that of sheet metal, and the existing piles corresponding to patents US-A-1441316 and US-A-1506578 whose shape is too rounded and the weight and too heavy to be able to follow the shapes of the existing curvatures of body.
  • certain locations in vehicles (the doors, fenders) require the use of space-saving heaps to be able to access the area to be removed, which is not the case with already existing parts.
  • the object of the invention is to overcome these drawbacks. This item is hit by a sheet metal heap game according to claim 1.
  • the pile (1) is intended to be used in flat and curved sectors in one direction as shown in Figure 3.
  • the pile (2) is intended for use in differently curved areas in both ways.
  • Figure 1 is a schematic perspective representation of the game of two heaps according to an embodiment of the invention.
  • Figure 2 is a schematic cross-sectional representation of one of the two heaps in Figure 1.
  • Figure 3 is a representation of a body roof under which are represented the heap of the invention and heaps according to the state of the art.
  • FIGS 4 and 5 show in detail an embodiment of the heaps of the game of heap according to the invention.
  • the pile (1) is slightly smaller heap (2), although these two elements could be the same length, is easily gripped in one hand, and has an elongated shape and thinned ending at its end (5) with a shape curved (radius of curvature 150 to 190 mm and advantageously close 170 mm; see Figure 4).
  • the end (13) of the pile (1) is the thickest, has two edges (9) and (10), also rounded.
  • the radius of curvature of the edge (9) is much shorter than that of the edge (10), so that the curvature (9) is much more pronounced than the edge (10), the radius of curvature (19) can varied by thickness.
  • the upper face (3) (from one end to the other) is slightly curved in the transverse direction, as can be observed in FIG. 4.
  • the radius of curvature of this upper face, in the transverse plane is between 150 and 190 mm, and advantageously close to 170 mm.
  • the upper face first of all has a substantially flat profile (radius of curvature of 170 mm) near the end (13) over a distance of 50 mm, then gradually bends with a radius of curvature which varies from 150 to about 48 mm.
  • the anterior end (5) is located in a plane underlying with respect to the plane containing the base (7) of the heap (1).
  • the base (7) is composed of a perfectly flat part of length 70 mm, and a rounded part joining the end (5) with a curvature of 56.5 mm.
  • the zone (5) and the base (7) converge, defining a rounding of 2 mm.
  • the two side faces (15) and (16) are parallel and perfectly flat. They define with the upper and lower faces edges whose radius of curvature is 1 mm.
  • the relative inclination of the upper face (3) relative to the base (7) is between 3 and 10 °, and advantageously close to 5 °.
  • the pile (2) is slightly larger heap (1), has an elongated shape ending at its end (6) by a curved and thinned shape (radius of curvature 55 mm).
  • the edge (11, 12) can take curvature according to the modification of the thickness of the end (14).
  • the upper face (4) (from one end to another) is curved in the transverse direction, as can be seen in Figure (5).
  • the radius of curvature of this upper face, in the transverse direction is between 256 mm (zone 14), 93.5 mm (zone 4), and 55 mm (edge (6)).
  • the upper face presents over a distance of 90 mm, a substantially flat profile (radius of curvature greater than 250 mm), then gradually bends with a varying radius of curvature from 64 mm to 16 mm.
  • the anterior end (6) is located in an underlying plane relative to the plan containing the base (8) of the heap (2).
  • the base (8) is composed of a part perfectly flat, 116 mm long, with a rounded part joining the end (6) with a curvature of 21.5 mm.
  • the end (6) and the base (8) are converge by defining a rounding of 2 mm.
  • the two side faces (17) and (18) are parallel and perfectly flat. They define with the upper and lower faces edges whose radius of curvature is 2 mm.
  • the relative tilt of the face upper (4) relative to the base (8) is approximately 2 ° which can vary in as a function of the change in pile thickness (2).
  • the piles (1) and (2) presented in Figure 1 have as maximum thickness from 26 to 35 mm with change in the curvatures of the edges (9, 10; 11, 12).
  • the heap dimensions (1) can be changed in length and width according to the profession.
  • the heap (1) of smaller dimension, is more precisely intended for straightening and removing roughly frustoconical sheets curved in one direction.
  • the anterior zone (5) is intended to allow to enter the level of the narrower zones and the angles of bodywork or sheet metal.
  • the pile (2) is intended more particularly to unravel sections bent in both directions.
  • the tables (I to IV) below represent the curvatures and their evolution in areas of 10 mm thickness starting from the end (5) to (13) for the pile (1) and from the 'end (6) to (14) for the pile (2).
  • TAS I AREAS FROM (5); (mm) Longitudinal radius of curvature (mm) Upper side Lower side 10 45 56.5 20 48 30 70 40 148 50 150 dish 60 > 250 70 80 90 100 110 8 9 The two faces meet with a curvature of 30 mm.
  • the pile (2) allows the deburring of practically all the curvatures used in the automobile body slight.
  • the two heaps (1) and (2) are easily adaptable to work of straightening and deburring for the bodywork of heavy goods vehicles or thicker sheets, changing the thickness, and for the pile (1) the width from 40 to 50 mm.
  • the heap game of the invention therefore makes it easy to replace the devices known to date, and especially to reduce the number of parts necessary for the straightening and deburring of the sheets.
