Definitions

  • ABSTRACT For corrugating metal sheet, a plurality of movable vises, typically three vises arranged substantially in linear series such that a flat metal sheet is extendable between the open jaws of all the vises and preferably an elongated form mounted at one end thereof and movable to and fro axially and to and fro upwardly and downwardly between upper and lower jaws of the intermediate second vise, the first and third vises being 1 equally spaced from the intermediate second vise and eachof the first and third vises being laterally movable toward one another to a predetermined closenes sTtli intermediate vise being movable upwardly and downwardly alternately, a preferred process including opening all vises jaws, placing a'metal sheet at a position between opposing jaws of all vises, thereafter clamping closed the jaws of all vises with the first and third vises each spaced a predetermined first distance on about opposite sides of the intermediate vise, thereafter elevating the intermediate closed vise while per
  • an object of the present invention is to obtain a machine and process of making practically any desired shape in an economic way.
  • the invention includes a plurality of normally lineally aligned vises in series, with the vises being movable and maneuverable as follows.
  • the jaws of an intermediate one of typically three serially aligned vises are operable a predetermined distance, and the face of the jaw of at least one of the jaws of the intermediate vise conforms to a central part of its desired shape.
  • the closed vise as a whole is movablein a plane vertical or transverse to the sheet metal commonly extendable between open jaws of the aligned jaws.
  • the first and third vises are movable toward one-another to and fro laterally along the plane of the sheet metal (or formable plastic sheet).
  • An additional vise movable laterally along the place of the surface of the metal sheet, or alternatively pincher rollers capable of advancing the sheet, intermittently advance the sheet between forming steps.
  • the first and third vises become dragged laterally toward one-another while the intermediate second vise moves transversely (such as upward) to the sheet surface followed by withdrawal of the second vise jaw which was pushing against the now concave surface of the sheet, thereafter advancing the first and third vises further toward each other to thereby further close the partial or complete enclosure (tube-like being normally open on opposite ends), and thereafter return all three vises to their open starting positions.
  • FIG. 1-11 show a complete working cycle to make a corrugation.
  • FIG. 12-14 show three phases of the making of another corrugation.
  • FIG. -17 show three phases of the making of the same corrugation, but in another way.
  • FIG. 18-20 show an application of metal sheet, corrugated accordingto the invention.
  • FIG. 1 is a perspective view in which the metal sheet 1 has to be corrugated. It is held fast by horizontally movable clamps 3a-b and 4a-b.
  • a vertically movable forming die beam 512 is situated under the metal sheet 1, a vertically movable counter die beam 5a is situated over it.
  • a transversely and vertically movable folding rod 6 is situated at the side of the metal sheet 1 and the die 5b with counter die' 5a.
  • a horizontally movable feeding clamp 2a-b has in a former working phase transported the metal sheet 1 to the position shown (see FIG. 11), and returned after that in open position to its starting position (see FIG. 1).
  • FIG. 2-10 schematic views of cross sections along A-A in FIG. 1 are shown.
  • FIG. 11 is the same along B-B in FIG. 1 with a different position of the feeding clamp 2a-b.
  • FIG. 2 shows in transverse section the situation of FIG. 1.
  • the folding rod 6 is moved transversely into the cavity in metal sheet 1, see FIG. 5, after which the folding rod is lifted till it reaches the top of the cavity, see FIG. 6. It is also possible in this phase to force down the counter die 5a till the metal sheet touches the folding rod 6.
  • the stops 8c-d and 9c-d are removed, as shown by moving them downwards, whereby the clamps 3a-b and 4a-b which were held by the stops 8c-d and 9c-d move further towards each other, see FIG. 7.
  • the bottom sides of folding rod 6 form the next stops for clamps 3a-b and 40-h. Often it will be necessary to install separate stops here.
  • the corrugation has now been shaped, and should be set free.
  • the upper halves 3a and 4a of the clamps 3ab and 4a-b are lifted a bit as well as folding rod 6 and counter die 5a. The latter moves here a bit more upward till it is free from the profiling, see FIG. 8. It is also possible instead of lifting 3a and 4a to lower 3b and 4121. Clamps 3a-b and 4a-b are brought back into their initial position and the corrugation lies free, excepting the enclosing bu folding rod 6.
  • the corrugation tends to take a distance, however small, fromthe folding rod 6, and it can be pulled away transversely, preferably after the metal sheet 1 is in its horizontal position again, see FIG. 10.
  • upper half 4a of clamp 4a-b has been lifted so high, that corrugation 10 can pass under it to the right.
  • Stops 8c-d and 9c-d are also brought in their initial position.
  • Metal sheet 1 with its new corrugation is :now pushed to the right as feeding clamp 2a-b, which as shown in FIG. 1 was opened in its utmost left position, shuts and moves to the right, where it is stopped by stops 7c-d, see FIG.
  • FIG. 12-14 only a counter die
  • FIG. -17 only a folding rod
  • Not all phases are shown here.
  • the phase shown in FIG. 13 and 15 corresponds with that of FIG. 1 and 2, that of FIG. 13 and 16 with the phase of FIGS. 4 and 5, and the phase shown in FIG. 14 and 17 corresponds with that of FIG. 7.
  • FIG. 18-20 an application is illustrated of the corrugation 10, see FIG. 19, made according to FIG.-
  • FIG. 18 a low cost-high efficiency radiator is shown. It consists of a system of round pipes, see FIG. 20, with straight pipe parts 14, upon which by snap action metal sheet 13 is fastened, see FIG. 19. This has been partially provided with corrugations 10, while the flat ends of the sheet have been bent as illustrated. Together with a cover 15 and a bottom 16', see FIG. 18, the radiator is complete.
  • the specific properties of the metal sheet handled for instance its elasticity. With great elasticity considerable spring back from the folded position as shown in FIG. 7, l4 and 17 is possible.
  • the lower side of counter die 5a may consist of two symmetric parts which move towards each other horizontally when the metal sheet 1 is introduced while forming die 5b comes up.
  • the folding rod 6 may be used as a support for the folding rod 6 when inserting it from the side. It is also possible in many cases to make the folding rod 6 the loose top of the forming die 5b. In this case when withdrawing the forming die 5b (FIG. 3) the folding rod 6 may remain fixed in its highest position. After folding the metal sheet 1 around the folding rod 6 and loosening the corrugation 10, the folding rod may be pulled away transversely after which it is lowered till forming die 51; height is reached and then be pushed transversely so that it will form a loose top of the forming die 5b again.
  • a machine for corrugating a formable sheet comprising in combination: a plurality of about lineally aligned vises each having opposing upper and lower jaws including at least first, second, and third vises, the first and third vises being movable to and fro toward and away-from each other along a plane in which a formable sheet surface is extendable commonly and concurrently between the opposing jaws of the first, second, and third vises, and the intermediate second vise being movable to and fro transversely to said plane of said sheet surface, and when said second vise is opened said first and third vises being movable along said plane between opposing open jaws of said second vise; and including an elongated form having a flattened face between opposite sides mounted at one end thereof and movable to and fro axially and to and fro transversely to said plane, said elongated form being axially movable to a position intermediate between said first and third vises when said second vises jaws are open and
  • a machine of claim 1 including elongated form means for moving said elongated form to a position between open opposing jaws of said second vise and for thereafter moving the elongated forms flattened face transversely to said plane into substantially axially parallel relationship with a clamping face of one of the second vise jaws, and first and third vise means for thereafter converging said first and third vises toward oneanother when in a closed state to positions adjacent each respectively of said opposite sides.
  • said first and third vise means is further for opening jaws respectively of the first and third vises subsequent to said converging and for thereafter diverging said first and third vises from one-another; and additionally including second vise means for moving the jaw which is in juxtaposition to the elongated form, to a position further away from the flattened face subsequent to said diverging, and said elongated from means further being for axially withdrawing said elongated form subsequent to said diverging.
  • a machine of claim 3 including stop-limiting means for blocking converging movement of closed first and third vises after a predetermined amount of converging along said plane when said second vise in a closed state moves transversely from between said first and third closed vises.
