Abstract

The die set comprises a hollow die 24 having an internal forming portion 42 for supporting badge parts 10, 12, 14. A ring 22 is engageable in the die by latching elements 32 which co-operate with elements on the die. The marginal edges of the badge parts are bent initially over a cylindrical member (28, Figure 8) received in the die and these edges are then formed by insertion of a pressure member 26 in the die. A backing (16, Fig 10) is then inserted in the die and a hammer member (20) is engaged in the die and folds back the badge part edges to secure all the parts together. The latching elements engage by rotation to lock the ring and the die together axially. <IMAGE>

Description

SPECIFICATION Die set for making badges This invention relates to a die set for use in making badges or buttons.

US-A-4 299 019 discloses a set of five die members and a metal member locking two of the dies together. The present invention avoids the necessity for providing the mechanical means for latching two of the dies together and a substantial improvement over the disclosure of US-A-4 299 019.

The present invention provides a die set for making buttons or badges comprising a hollow cylindrical forming die for receiving overlying button or badge parts, a cylindrical ring and central member for location in the die for bending marginal edges of said parts over the central member, a cylindrical pressure member locatable in the die for forming said marginal edges in the die, and a hammer member locatable in the die for folding back the marginal edges to lock the parts together, the die and the ring having latching elements which cooperate to lock the die and ring together against relative axial movement.

Reference is now made to the accompanying drawings, wherein: Figure 1 is an exploded view of the die parts of a die set according to the present invention; Figure 2 is an exploded view of the badge (or button) parts; Figure 3 is a plan view taken on the line 3-3 of the die set of Figure 1; Figure 4 is a cross-sectional view taken on the line 4-4 of the die set of Figure 1; Figure 5 is a plan view of a ring of the die set taken on the line 5-5 of Figure 1; Figure 6 is a cross-sectional view taken on the line 6-6 of the ring in Figure 1; Figure 7 is an end elevational view partially in cross-section of die parts, showing the first step in latching the ring and forming the die with the badge parts in place;; Figure 8 is a partial vertical cross-sectional view with parts removed illustrating a second step of making the badge, Figure 9 is a partial vertical cross-sectional view illustrating a third step in making the badge; Figure 10 is a partial vertical cross-sectional view illustrating a fourth step in making the badge; Figure 11 is a partial vertical cross-section of the final step after placing the parts shown in Figure 10 in a hand press or the like to produce a final badge; and Figure 12 is a perspective view, with parts broken away, illustrating a locking pin.

The parts of a pin-back badge to be made are shown in Figure 2 and comprise a shallow, axially flanged, metal shell 10 over which a circular paper disc 12 carrying a picture or message, and a circular, transparent plastics disc 14 are applied to, and a body or backing disk 16 carries a pin 18 by which the badge may be removably attached to the wearer's clothing. These components of the badge are conventional and readily available pre-formed devices, and form no part of the present invention.

As shown in Figure 1, the die set comprises generally a cylindrical hammer 20, a cylindrical ring 22, a ring-like forming die 24, a cylindrical pressure member 26 and a cylindrical member 28 of a height twice that of the ring 22. All parts are produced from a hard plastics material.

The ring 22 is provided with three integrally formed locking ears 30 located substantially medially of the outer sides of the ring 22 and positioned 1200 apart. One end of each of the ears is provided with an integrally formed, right angled stop member 32.

The forming die 24 has a supporting wall 36 provided with three integrally formed latching pins 34 formed on the bottom area of the die 24 at the peripheral edge thereof. It is to be noted that the periphery of the die 24 adjacent the latching ears 34 and the wall 36 is enlarged as at 38 and extends outward of the outer edge of the die 24. The ears 30 are also provided with an integrally formed, tapered surface 40 that extends from the stop 32 to strengthen the structure.

The purpose of enlarging the portion 38 of the outer wall of the forming die is to allow ample room for the reception of the locking pins 34 within the rear wall 36 and under the ear members 30 in the assembly.

The die 24 is provided with a coated steel member 42 integrally formed on its inner surface and at one end is formed with a flat radial surface 44 defined by a rim 46. The inner diameter of the forming die 24 at this one end is the same as the inner diameter of the ring 22 to serve as a continuation thereof and to provide a wall 48 which terminates in an inwardly and downwardly curved shoulder 50 which in turn defines the upper end of wall 48 extending to the other end of the forming die 24.

The length of the wall 48 is preferably only slightly longer than the width of the flange 52 of the shell 10, so that the free end of the flange 52 can rest on the shoulder 50.

The ring 22 has an outside diameter substantially equal to or less than the inner diameter of the wall 48 of the die.

It is also to be noted that the exterior of the diameter of hammer member 20, the pressure member 26 and the cylindrical member 28 is substantially equal to or less than the inner diameter of the forming die and ring member 22 to readily fit therein.

The ring 22 has concentric, axially parallel inside and outside walls and the internal diameter of ring 22, which is the same as the diameter of the badge to be made by the die set, determines the working diameter of all other elements of the die set. The axial length of this ring 22 also sets the axial measurement of the other elements of this set.

In operation, the forming die 24 is placed on a flat surface with the locking pins facing upwards.

The plain badge shell 10 is placed into the die 24 with the flanged edge facing downwardly. Next the discs 12, 14 are placed on top of the shell 10. The ring 22 is then placed in the die 24 and turned until the ears 30 are positioned under the locking pins 34. It is not necessary to abut the stop 32.

The die 24 and ring are then raised above the surface, the cylindrical member 28 is placed into the lower end of the die 24 and pressure is applied firmly and evenly on the ring 22 until it snaps down on the flat surface. (See Figure 8). The assembly 13 is then lifted off the cylindrical member 28 and replaced on the flat surface.

The pressure member 26 is then placed in the ring 22 as shown in Figure 9 and with the palm of the hand pressed firmly downwardly until the downward movement stops, thus causing the flanged portion of the badge front to shift inwardly.

The assembly of the forming die 24, ring 22 and member 26 is turned over so that the member 26 lies against the flat surface. The pin-back badge part 16, with the pin 18 uppermost, is then placed in forming die 24 which is now the uppermost part (See Figure 10). Then the hammer member 20 is placed in the forming die 24 and the entire die set is picked up and placed in the jaws of a hand or bench press and pressure applied whereby the discs 12, 14 will be locked to the flanges of the members 10 and 16 as seen in Figure 11.

Thus the die set differs from existing structures by the ears 30 and pins 34 for locking the forming die 24 and ring 22 together. Also, the member 28 has a height of twice the height of the ring and the same height of the forming die less the ears 30.

Also, fewer operations are required to form a badge than the prior art.
