Definitions

  • the invention relates to a method for producing a cylindrical metal container for paint or the like. from a tinned sheet metal, which is cut into several flat, straight sheet metal pieces, each of which has two side edges, the length of which approximately corresponds to the circumference of the container and has two longitudinal edges, the length of which is approximately equal to the height of the container.
  • the invention relates primarily to an improvement in the manufacture of cylindrical paint containers using a wire hanger or wire handle to carry the container, and is described with particular reference thereto.
  • the known method for producing cylindrical metal containers for paint in particular with the capacity for one gallon, has hitherto consisted in embossing the lifting eye into a cup-shaped form, the cup having a base area with an opening penetrating it and an edge from which a circular flange went out.
  • the tinned metal material was punched out into a variety of straight, flat sheet metal pieces and each sheet metal piece passed through different hot pressing stations, which continuously provided the sheet metal piece with impressions to create a recess for receiving the eyelets.
  • the piece of sheet metal was then bent over the flanges of the eyelets to hold the eyelets in place.
  • the sheet metal piece was formed in this way and pressed around the eyelet flanges, the sheet metal piece was rolled or rolled into a cylindrical shape and the longitudinal edge of the sheet was bent back or overlapped with the adjacent edge to produce a soldered seam to form a longitudinal fold connected by resistance welding.
  • the bottom of the container was then double-folded at one end of the cylinder and a ring was double-folded at the other end of the cylinder in a known manner.
  • the longitudinal fold connected by resistance welding emerges and can adversely affect the sealing of the lid.
  • the overlap becomes important when the can or container is to absorb water-based paints.
  • the fold is coated with a sprayed-on strip to prevent rusting. If the If the overlap increases, the coating cannot enter the space between the overlapping metal edges.
  • a sprayed-on strip can still penetrate effectively in an overlap of approximately 0.4 to 0.5 mm. typical distortion of the straight edge typically reach 1 mm.
  • the object of the invention is to provide a method for producing a cylindrical metal container, according to which the eyelets can be fastened to the container very quickly and effectively by resistance welding.
  • each piece of sheet metal has a cup-shaped body which has a circular base with an opening penetrating it for receiving a wire bracket and a circular edge part, and wherein each eyelet has two diametrically opposed, substantially rectilinear lobes extending from the edge.
  • Two eyelets are placed in separate locations on a flat piece of sheet metal, with each eyelet being oriented so that its tabs are substantially perpendicular to the side edges and substantially parallel to the longitudinal edges of the sheet piece. Then the tabs are attached to the sheet metal piece by resistance welding while it is in a flat position.
  • the piece of sheet metal is then rolled or rolled precisely at its side edges into a smooth cylindrical shape, one longitudinal edge overlapping the other longitudinal edge, whereupon the longitudinal edges are folded in the longitudinal direction and the container is then shaped in a known manner.
  • the rectilinear longitudinal edges are not deformed by fastening the tabs by resistance welding to the sheet metal piece, so that when overlapping one longitudinal edge overlaps the other no more than about 0.04 mm. This enables rapid resistance welding of the longitudinal fold, the size of the metal piece required to produce the container being minimized and the costs required for this being reduced.
  • the tabs are preferably welded to the flat piece of sheet metal by resistance welding. This makes it possible to weld rags at a speed of approximately 250 pieces of sheet per minute, which is a significant acceleration compared to the known method used for projection welding of the eyelets.
  • the method according to the invention has the advantage that the overlap of the longitudinal edges can be precisely controlled. Furthermore, the amount of metal material that is otherwise required in the process is minimized. In addition, with the method according to the invention, it is possible to attach the eyelets precisely to a flat, rectangular metal sheet and to roll or roll them smoothly into a cylindrical can body.
  • a cup-shaped eyelet 10 is shown, which is used to hold the ends of a bracket or wire handle for carrying the container.
  • the cup-shaped eyelet 10 has a base 12 and a circular edge 13. In the base 12 there is a central opening 15 which penetrates the eyelet and receives the ends of the bracket.
  • Two fastening tabs 16 extend from diametrically opposite sides of the edge 13.
  • the cup-shaped eyelet 10 is made by conventional hot pressing from a material which is 95 lbs. (0.0105 ”) tinplate.
  • the diameter of the base plate 12 is designated by D, which is approximately 0.750 ".
  • the width W of the fastening tabs 16 is approximately 40% of the diameter D and the length L of the tabs 16 makes approximately 25% of the diameter D. out.
  • the first step consists in forming a cylindrical body or can body from a flat piece of sheet metal.
  • the piece of sheet metal was cut from the sheet metal into a rectilinear plate 20 which has mutually parallel, upper and lower edges 21, the length of which is approximately equal to the circumference of the cylindrical container and the mutually parallel longitudinal edges 22 which are approximately equal to the height of the paint container .
  • On the rectangular plate 20 there are two eyelets which are located at a mutual distance from one another which corresponds to the diameter of the paint container, but is also not equal to half the container circumference.
  • the diameter would be approximately 6,500 "and the dimensions" a "and” b "in Figure 2 would be equal to 5,110" and 1,745 ", respectively.
  • the eyelets 10 can be positioned precisely on it and easily clamped or otherwise attached to weld the tabs 16 to the straight sheet 20.
  • a common Larson hump welding machine could be used to weld the tabs 16 to the right angle sheet piece 20.
  • Such a machine has the capacity to weld 0.3 eyelets / second, which would produce 20 can bodies / minute when used in conjunction with known feeders, such as commonly used in cans production lines are used.
  • the tabs 16 be resistance welded to a rectangular piece of sheet metal 20 by a resistance welding machine 30 as shown schematically in Fig. 3a.
  • Such resistance welding machines could be of the type used to produce a continuous longitudinal fold (explained in more detail below) and modified to fix the tabs by resistance welding as the piece of sheet metal passes.
  • Particularly modified projection welding machines could significantly reduce the welding time and it can be assumed that approximately 250 straight sheet metal pieces / minute can be passed through such a specially adapted projection welding machine.
  • the thickness of the sheet metal plus the fastening tabs 16 is approximately twice the thickness of the rectangular sheet metal piece 20 and welded connections are only present at two locations which are at a vertical distance from one another and parallel to the longitudinal edge 22 and are arranged perpendicular to the upper and lower side edge 21.
  • This important feature allows the right-angled sheet metal piece 20 to be rolled or rolled into a proper cylinder using conventional cylinder profile rolls 40, as shown schematically in Fig. 3b.
  • a conventional cylinder profile roller machine for example the model no. EWL-250 from Soudronic AG or the model no. FBW-22-420-S from Fael AG can be used, which is also used in known systems.
  • the machines described are profile rolling machines, in contrast to other known cylinder rolling machines, which could theoretically also be used.
  • the welded connection between the tabs 16 and the rectangular plate 20 must not loosen during the rolling, while at the same time an accurate rolling
  • the dimensions given above are limit values without being able to push in the can side wall.
  • the overlap of the longitudinal edges 22 can be precisely controlled and is actually carefully controlled so that it is not more than 0.5 mm.
  • a conventional longitudinal seam welding machine that could be used to perform the longitudinal seam welding are, for example, the EWL-250 model from Soudronic A.G. or the model FBW-22-420-S from Fael A.G.
  • a cylindrical can body 60 is formed and this can body is then subjected to the normal manufacturing steps in can making, which include folding a bottom at one end 61 and a ring at the other end 60 of the can body 62. If the can body is a ringless can body, the second end 60 is appropriately profiled.
  • the flat sheet metal piece 20 has previously been processed by a series of tools which impressed impressions into the rectangular sheet metal at the points where the eyelets 10 are welded on.
  • the straight longitudinal edge 22 is distorted. This distortion, which occurs irregularly and is indicated by dimension X in Fig. 4, would exceed 0.5 mm and sometimes reach 1.0 mm. This is more than twice the allowable distance for water-based paint containers using the spray strip method mentioned above.
  • the main idea of the invention is therefore to propose an improvement in the manufacture of cylindrical metal containers, which allows the permanent attachment of eyelets to the straight sheet in its flat state in such a way that the cylinder of the can body is then accurate and without distortion of the straight longitudinal edges of the rectangular sheet can be shaped.
