Definitions
- the object of the invention is a cable reel, which includes a drum and ends i.e. flanges attached to both sides, and in which curved tabs formed in the ends of the drum and extending in an axial direction through the ends are used in the attachment of the drum and the ends, in which corresponding curved slots are formed and the parts of the tabs extending beyond the ends are bent onto the external surface of the ends.
- the invention is also concerned with a method for manufacturing a cable reel.
- Known cable reels are generally made from wood strips and thicker wood.
- the end disks are manufactured from sheets of wood strips laid crosswise.
- the drum is typically made from slightly conical strips, from which a cylindrical component is formed.
- the above manufacturing technique for large drums is time- consuming and the drums have a considerable weight.
- This inven ⁇ tion is mainly concerned with cable reels in which the drum diameter is 150 mm or greater.
- Small cable reels are manufac- tured as one piece by either moulding or spray-pressing from plastic, but this method is not suitable for large reels.
- US publication 3,544,032 presents a cable reel of the type referred to in the introduction.
- the tabs of the drum are fed through openings in the ends and bent.
- the tabs are very narrow and their protrusion is small. It does not require a very great force to bend them, especially if the opening is in the form of a triangle or rectangle.
- the published literature 3,544,032 presents a cable reel of the type referred to in the introduction.
- the tabs of the drum are fed through openings in the ends and bent.
- the tabs are very narrow and their protrusion is small. It does not require a very great force to bend them, especially if the opening is in the form of a triangle or rectangle.
- the republic ⁇ cation does not show means for bending larger tabs.
- the intention of this invention is a stronger cable reel than previously, the manufacture of which is simple.
- the characteris ⁇ tic features of the invention are presented in the accompanying Patent Claims.
- the invention is to a great extent based on the realization that essentially in bending each curved sheet-metal part deformation work must be carried out, which on the other hand the load would have to do in reverse in order to separate the end from the drum.
- the deformation of the tabs locks them effectively in place.
- the optimal deformation requires a precise shape for the curved opening. Due to the great deformation work it is advantageous and often essential to use a machine tool for bending. This sweeps a local formation over the entire length of the tab.
- Figure 1 shows a drum and end before they are attached to one another.
- Figure 2 shows a finished cable reel.
- Figure 3 shows a detail of the cable reel in partial cross- section.
- Figure 4 shows a cross-section of the construction of an end.
- Figure 5 shows a cross-section of the seam of the drum.
- Figure 6 shows the mechanical bending of the tabs.
- Figure 7 shows the manufacture of an end by die-cutting.
- the principal components of a cable reel are here two ends 1 and 2 and the drum 3 between them.
- the drum is most advantageously manufactured from galvanized sheet steel, with a thickness of 0,3 - 2 mm, corresponding to drum sizes of 160 - 1200 mm.
- the ends are most advantageously made from birch or mixed plywood, but other strong boards, such as particle board or chipboard, may be considered.
- the manufacture of the cable reel begins by cutting an essentially rectangularly shaped piece of sheet steel, on both edges of which indentation are cut in order to make tabs 4. The bends to be made for seam 10 appear later.
- the drum in accordance with Figure 1 is bent from the sheet and the seam 10 is secured.
- disc 1 is made from birch plywood in which the curved openings 11 are formed.
- Figure 2 shows a finished drum, in which the fold 14 of the tab 4 onto the outer surface of the end 1 can be seen.
- the Figure shows in broken lines a support disc 3, which, if addition strength is required, can be attached to the end disc 1, before the drum 2 is attached to it.
- the support disc 3 carries the drum over its entire circumference and thus provides the construction with addition breaking strength.
- Figure 4 shows the joint between the drum 2 and the end 1 in detail. Here too the support disc 3 is visible. The tab 4 has been pushed through the curved opening 11 of the drum and its end has been turned, when the folds 14 can be seen against the end 1.
- the cable reel with its cable can be advantageously protected by means of a sheet metal cover 8, in each edge of which a groove 9 is formed.
- a sheet metal cover 8 in each edge of which a groove 9 is formed.
- This is made from an essentially rectangular piece of sheet metal, which is formed into a cylindrical cover around the drum.
- the ends include suitable locking devices, e.g. foldable tabs, by means of which the sheet is made to remain on top of the drum.
- the tabs of the drum extend advantageously 9 - 12 mm from the end. In any event the protrusion is between 7 - 20 mm. In general tabs longer than 12 mm remain ⁇ • grinning" above the surface of the end, because the stress created during the bending does not really extend beyond 10 mm.
- Forming carried out by means of device in accordance with Figure 6 pulls the tabs outwards, in which case the curved parts of the drum 2 between the tabs bit into the inside surface of the ends. It is possible to make small curved grooves for them if it is desired to increase the load- bearing capacity in this area. In any case the curved parts cut more or less into the inner surface of the ends, creating a support for the drum over the entire circum ⁇ ference.
- the seam 10 of the drum 2 is formed by overlapping the ends of the metal sheet in such a way that bend 5 is formed in the sheet that remains underneath, by means of which places itself easily under the opposite end of the sheet in accordance with Figure 5.
- the ends of the sheet are secured to one another by point welding 6, when a strong and even seam 10 is obtained.
- a cable reel with a diameter os 500 mm, in which a 240 mm drum was used was manufactured as follows. 0,7 mm thick galvanized steel sheet was used in the drum and 15 mm thick birch plywood in the ends. There were four tabs and they had a length of 100 mm (curved dimension) .
- a 1500 mm diameter end was manufactured from 25 mm thick birch plywood and the 1100 mm drum in it was made from 1,25 mm galvanized sheet steel. There were eight tabs and these had a length of 100 mm.
- a drum of diameter of 150 - 1500 mm galvanized sheet steel with a thickness of 0,3 - 2 mm is used, adapted in such a way that the thickness s of the sheet of the drum 2, the width 1 of the tab 4, and the diameter D of the drum 2 fill the following conditions: _, _, _,
- Inner discs are used in drums with a diameter of 600 mm or greater, though it is possible to replace them by increasing the material thickness in both the drum and end boards. In these too an inner drum can be used, if it is desired to further strengthen the construction.
- a longitudinal blank 22 is moved through die 16, which cuts the ready end boards 1 from it.
- the die 16 consists of a fixed lower section and upper part that strikes against it, of which only the cutting blades are drawn visibly. Openings for the tabs are formed by striking the upper curved blade 18 against the curved opening blade 17 of the lower part. A thin curved piece is removed through the lower blade 17. At the time the entire end disc can be die-cut from a blank board by means of blade 19. If required a centre opening 21 can be formed by the same strike with blade 20.
