Definitions

  • This invention relates in general to the working of thin sheet material and more particularly to an improved means for forming a bead on such material.
  • hollow bodies comprising one or more thicknesses of thin material of various types, designed for various purposes such as packings, it is essential to eliminate the sharp edge of the blank, previously cut and stamped out, and to give it the form of a bead in order to increase the resistance of the article and improve its appearance.
  • An object of the invention is to provide a simple and efficient means for providing such blanks with beads.
  • Figure l is a View in Vertical section through a part of the device showing the relationship of the parts'prior to the beading operation.
  • Figure 2 is a similar view showing the heading members in operative position.
  • Figure 3 is a view in section, taken along line 3-3 of Figure 2.
  • the device may include a fixed cylinder l with a closed flanged base 2. Inside the cylinder is a slidable matrix 3 normally urged upwardly by the compression coil spring 4 extending between the matrix and the base 2. Slidably arranged about the cylinder is a sleeve 5 with a peripheral flange 6. Superimposed on the flange 6 are arranged three sectors 'i each of which is provided with bolts 3 extending through elongated non-radial slots 9 in flange 6, the bolts being provided with enlarged beads IQ of greater diameter than the width of the slots 9.
  • the sectors 1 held against vertical movement with respect to flange 6, but are slidably movable on the flange 6 so that the sector assembly is radially expandible and contractible concentrically.
  • the sleeve 5 has pivotally connected thereto at H a link l2.
  • a lever M To the opposite end l3 of the link is pivotally connected a lever M, which is pivotally connected at 15 to a stationary bracket E6 on the base.
  • an operating rod l8 To the other end of lever I4 is pivotally connected at ll an operating rod l8.
  • This operating rod is operated so as to be moved upwardly and downwardly to a predetermined r extent and at predetermined intervals by any suitable means such as a cam actuating drive from a suitable power source.
  • levers 2i Pivotally connected at it to the flange 2!] of the sleeve 5 are levers 2i urged inwardly or in a clock- 10 wise direction as viewed in Figures 1 and 2 by any suitable means such as a leaf spring 35.
  • are rounded at 22 which extend upwardly through radially elongated slots 23 in flange 6 of the sleeve 5 and upwardly so as to fit reasonably snugly but rotatably in holes 24 in each sector 1.
  • the levers 2! are each formed with a rounded cam portion 25 which fit in a hole 25 in sleeve 5 and extend therethrough into a recess 21 in the outer wall of the cylinder i.
  • the sectors are each provided near the inner edges with a semicircular groove 28 arcuate in length on the under side of the sectors.
  • a complementary groove 29 is formed in the upper edge of the cylinder I.
  • a reciprocatory stamping punch 3i is shown in Figure 1 as having forced a blank 30 of material, to be Worked, in its downward position in the correspondingly countersunk portion of the matrix to receive the lower frustoconical extremity 32 of the punch.
  • moves downwardly punching the sheet into the matrix 3 and forming a cup-shaped member.
  • the matrix 3 is displaced downwardly compressing the spring 4.
  • the rod !8 is in its lower-most position with the sleeve 5 raised and the sectors I spread apart.
  • the rod i8 moves upwardly lowering the sleeve 5 until the cams 25 enter the grooves 21, causing the sectors l to move inwardly toward the punch 3
  • the spring 4 urges the matrix 3 upwardly forcing the free edge of the blank into the grooves 28 and 29 and curling them to form a bead.
  • stamping punch and the operating rod may be operated by any suitable mechanism in such a manner that the operations of the punch and rod take place in a predetermined relationship and sequence. It will also be seen that there has, by means of the above described apparatus, been provided a simple and efficient means of providing the blank with a bead.
  • a device for forming a bead on a blank of sheet material a cylinder, a matrix reciprocable therein, a stamping punch reciprocable in said matrix and also adapted to move the latter downwardly to engage said blank therebetween and means including two elements having complementary semicircular grooves and relatively movable with respect to said matrix so as to bring said grooves into alignment with each other and to engage said blank for forming a bead around the periphery of said blank.
  • a device for forming a head on a blank of sheet material a cylinder, a matrix reciprocable therein, a stamping punch reciprocable in said matrix and also adapted to move the latter downwardly to engage said blank therebetween, a slidable sleeve arranged about said cylinder, said cylinder being formed with a groove in its upper edge, sectors carried by said sleeve provided with complementary grooves to engage the edge of said blank.
  • a cylinder In a device for forming a bead on a blank of sheet material, a cylinder, a matrix reciprocable therein, a stamping punch reciprocable in said matrix and also adapted to move the latter downwardly to engage said blank therebetween, a slidable sleeve arranged about said cylinder, said cylinder being formed with a groove in its upper edge, sectors carried by said sleeve provided with complementary grooves to engage the edge of said blank, an operating rod for reciprocating said outer sleeve, and means for causing said sectors to move outwardly and inwardly to engage the edge of said blank and compress the same in said grooves toform a bead on said edge.
  • a device for forming a bead on a blank of sheet material a cylinder, a matrix reciprocable therein, a stamping punch reciprocable in said matrix and also adapted to move the latter downwardly to engage said blank therebetween, a slidable sleeve arranged about said cylinder, said cylinder being formed with a groove in its upper edge, sectors carried by said sleeve provided with complementary grooves to engage the edge of said blank, an operating rod for reciprocating said outer sleeve, and means for causing said sectors to move outwardly and inwardly to engage the edge of said blank and compress the same in said grooves to form a bead on said edge, said means comprising pivoted levers connected to said outer sleeve and to said sectors and provided with cam faces engaging recesses in said cylinder to move said levers and sectors inwardly and outwardly during predetermined portions of the reciprocations of said sleeve and sectors together.
  • a cylinder for forming a bead on a blank of sheet material, a cylinder, a matrix reciprocable therein, a stamping punch reciprocable in said matrix and also adapted to move the latter downwardly to engage said blank therebetween, a slidable sleeve arranged about said cylinder, said cylinder being formed with a groove and its upper edge, sectors carried by said sleeve provided with complementary grooves to engage the edge of said blank, an operating rod for reciprocating said outer sleeve, and means for causing said sectors to move outwardly and inwardly to engage the edge of said blank and compress the same in.
  • said means comprising pivoted levers connected to said outer sleeve and to said sectors and provided with cam faces engaging recesses in said cylinder to move said levers and sectors inwardly and outwardly during predetermined portions of the reciprocations of said sleeve and sectors together and cooperating bolts and slots for guiding the movements of said sectors concentrically inwardly and outwardly.
  • a device for forming a bead on a blank of sheet material the combination of cooperating means for shaping a blank, said cooperating means being shiftable in one direction during the shaping operation, bead forming means shiftable toward the said cooperating means to engage the edge of the blank at the conclusion of a shaping operation, and means for moving the said cooperating means in the opposite direction to force the edge of the blank into the bead forming means to form a beaded edge on-the blank.
