Definitions

  • the present disclosure relates generally to a joining apparatus and more particularly to a metal-working die assembly and the method for its assembling.
  • a die assembly and method are disclosed in US 5479687 A and US2006/196034 A1 respectively, for example.
  • Other examples of joining devices are disclosed in US 5479687 , US 2006/196034 , US 5727302 and US 8650730 .
  • a metal joining apparatus 2 according to claim 1 and a method for assembling the die assembly according to claim 11 are provided.
  • a single piece die guard includes an integral die shield section and an integral retainer section wherein a die anvil can be removed.
  • a further aspect employs a workpiece-facing surface of a die guard having a generally uniform height at both a die shield section and a retainer section with a separately insertable anvil and/or die body.
  • a method of assembling a die assembly includes inserting a die blade sub-assembly into one end of a bore of a die guard, and inserting at least a portion of a die having an anvil into an opposite end of the same bore in the die guard.
  • Yet another aspect discloses an apparatus and a method of assembling a die assembly wherein a laterally enlarged flange of a die is removeably trapped between a backside of a die guard and an actuator frame to which the die guard is removeably secured, with a workpiece-clinching anvil projecting from the die within the die guard.
  • the present apparatus according to claim 1 and method according to claim 11 are advantageous over traditional devices and solve the aforementioned problems.
  • the integral shield and retainer sections reduce separate parts while providing a low height profile to more easily access workpieces.
  • the present design makes assembly and disassembly of the die blades and the anvil much easier.
  • fewer parts and multifunctionality are beneficially achieved with the present apparatus. Additional advantages and features of the present apparatus and method can be ascertained from the following description and appended claims, taken in conjunction with the accompanying drawings.
  • a joining apparatus 31 is illustrated in Figures 1 - 5 and includes a metallic C-frame 33 with an actuator 35.
  • Actuator 35 is pneumatically or hydraulically powered. Alternately, it may be electromagnetically powered such as with an electric motor which drives an associated output transmission spindle.
  • a longitudinally elongated punch 37 and laterally surrounding stripper 39 are linearly advanced and retracted by activation of actuator 35.
  • Operator graspable handles 41 are coupled to a middle section of frame 33 and an eyelet 43 attached to an upper section of frame 33 is suspended from a vertically oriented cable having its opposite end attached to a manufacturing plant ceiling or associated overhead fixture.
  • an articulating robot may be coupled to the middle section of frame 33 for automated movement thereof.
  • Joining apparatus 31 further includes a die guard 51, also referred to as a die assembly 53, which is coupled to a mounting surface 55 of frame 33 via a threaded fastener 57.
  • Mounting surface 55 sits at the bottom of a depression or pocket 59 machined into a lower arm 61 of frame 33.
  • the mounting surface can simply be a flat plane of the frame or a stationary fixture.
  • fastener 57 is preferably a cap screw having a hexagonally shaped tool-receptacle internally within an enlarged head thereof.
  • Die guard 51 includes a shield section 71 and a retainer section 73, both located in the same and integral, single piece die guard part which is preferably machined from steel.
  • Shield section 71 includes an internally extending through-bore 75 (see Figure 11 ) which is longitudinally extending between a workpiece-facing surface 77 and a backside surface 79.
  • Multiple spaced apart apertures 81 radially extend through a curved wall of shield section 71 in directions generally perpendicular to the longitudinal centerline direction of through-bore 75. Apertures 81 functionally allow workpiece and manufacturing plant debris to fall out of shield section 71.
  • Apertures 81 are longitudinally closer to backside surface 79 than they are to workpice-facing surface 77. It is noteworthy that backside surface 79 includes a step 91 such that a longitudinal dimension 93, between the opposite surfaces 77 and 79 at shield section 71, is less than a similarly measured dimension 95 at retainer section 73.
  • Another through-bore 97 is located in retainer section 73 and is openly accessible in a direction generally parallel to that of die bore 75.
  • Retainer bore 97 includes an inwardly stepped shoulder 99 which receives the backside of the head of cap screw fastener 57.
  • the threaded end of a shaft of fastener 57 is rotatably received within an internally threaded hole in mounting surface 55 of the C-frame.
  • Opposite endwalls of shield and retainer sections 71 and 73, respectively, are somewhat semi-circular and curved when viewed in a top true-view, and sidewalls 101 spanning between the sections have a tapered true view appearance (see Figure 7 ) such that they are widest where they intersect a plane through a centerline of shield section 71 and are closest together where they intersect a plane through a centerline of fastener 57.
  • workpiece-facing surface 77 has a generally uniform and constant height at both the shield section and the retainer section including the connecting area therebetween. This provides a low profile height at or less than 10 mm off of backside surface 79 at dimension 95, and more preferably having a height of 9 mm or less. This low profile configuration advantageously allows die access to complicated backside surfaces of the workpieces otherwise not achievable with various prior designs.
  • die assembly 53 includes three die blades 121, an elastomeric and flexible biasing ring 123 and a die 125.
  • Each die blade 121 has a generally U-shape in cross-section with upper and lower outwardly extending feet 131 and 135, respectively, joined by a generally straight intermediate structure 137 which has an arcuate and smooth internal surface 139.
  • Ring 123 annularly surrounds intermediate structure 137 of die blades 121 and when the die blades are compressed together, internal surfaces 139 create a generally continuous circular-cylindrical shape.
  • Ring 123 preferably has a generally inverted U-cross-sectional shape with an open groove in a lower surface thereof to allow its bifurcated annular walls to compress together when a clinch joint 141 is formed between workpieces 45.
  • Die 125 includes a longitudinally elongated anvil 161 which centrally projects from a die body 163. Furthermore, die body 163 includes a circular and laterally enlarged shoulder 165 adjacent anvil 161 and a laterally enlarged and circular flange 167. Anvil 161, shoulder 165 and flange 167 are all coaxially aligned with each other and are a single integral piece made of steel. A locating pin 169 longitudinally and integrally projects from a centerline of die body 163 coaxially aligned with yet projecting opposite from anvil 161. Anvil 161 has a generally flat, workpiece-contacting upper surface 171 and a circular surrounding lateral surface 173 with an annular groove 175 therein. Peripheral surfaces of shoulder 165 and flange 167 are both smooth and flat in cross-section although a chamfer 177 may optionally be present at the lower corner of flange 167. Radii may also be present at surface intersections.
  • a metal-working leading end 63 of punch 37 is aligned with a centerline of anvil 161.
  • Clinch joint 141 interlocks together sheet metal workpieces 45 in an interlocking fashion with a generally circular expanded button located closest to the anvil and a cylindrically depressed cup shape on the punch side.
  • the clinch joint is preferably leak-proof and does not employ a separate fastener such as a rivet.
  • An inner surface 143 of shield section 71 has a centrally depressed annular groove 145 to receive an arm of ring 123, and a lower annular groove 147 to allow movement of foot 135 of die blades 121.
  • the assembly of the joining apparatus can best be observed with reference to Figures 10 - 16 .
  • the die blades, die and die guard are manufactured by machining and are then heat treated or coated as may be desired for the specific workpiece material to be clinched.
  • Elastomeric ring 123 is also injection-molded from a polymeric material.
  • die blades 121 are held together while ring 123 is located thereon as is shown in Figure 10 to create a die blade sub-assembly with the ring encircling and compressing the die blades together.
  • the die blade sub-assembly is inserted into a workpiece facing end of through-bore 75 in an offset orientation generally perpendicular to its final installed position as can be observed in Figures 11 and 12.
  • Figure 13 shows the next step where the die blade sub-assembly is rotated to its final installed position while inside of shield section 71 of the die guard.
  • die 125 is linearly inserted into the backside of bore 75, as can be seen in Figure 14 .
  • Anvil 161 is inserted internally within the central gap of die blades 121 until shoulder 165 aligns and snuggly fits internal to an inner bottom edge of die shield section 71, and the outwardly stepped flange 167 abuts and contacts against the stepped backside surface 79 as is shown in Figures 9 and 15 .
  • shoulder 165 snugly fits into shield section 71 but less than 10 Newtons and more preferably 9 or less Newtons of force is required to insert. The same force is required to later remove die 165 from shield section 71, which can be easily done by a person pushing a pencil or screwdriver against end 171 of anvil 161 during disassembly.
  • fastener 57 is thereafter inserted into its bore 97 in retainer section 73 to engage with a mounting surface of the C-frame.
  • fastener 57 tightly secures die guard 51 to the frame, flange 167 of die 125 is firmly trapped between the stepped backside surface 79 of the die guard and mounting surface 55 of the frame.
  • This avoids the need for a more permanent snap-fit interlock or extraneous fastening of the die to the shield section, thereby simplifying the manufacture of and disassembly of the die.
  • the anvil will become worn during repeated use such that replacement is desired, thereby utilizing the benefits of the present construction.
  • FIG 17 shows an alternate embodiment of the present joining apparatus.
  • This apparatus is identical to that previously disclosed except that a helically coiled compression spring 323 is employed instead of an elastomeric ring.
  • This flexible spring 323 annularly surrounds the intermediate structure in the middle of the die blades within shield section 71 of die guard 51.
  • Spring 323 can be employed with any of the embodiments disclosed above or after.
  • Figure 18 illustrates another embodiment of the joining apparatus that is the same as those previously discussed except that the die blades and anvil face are differently shaped.
  • the anvil face is concave for this version.
  • the present exemplary die blades 321 include chamfers 322 at the inner and upper corners thereof. During clinching joint formation, these chamfers 322 create three pinched corners on the adjacent button of the workpiece which contacts against the upper edges of die blades 321 and anvil 161 of the die. These chamfers provide relief when the material flows to form the clinch button, particularly for sheet aluminum workpieces.
  • Figure 19 illustrates still another embodiment of the present joining apparatus that is essentially identical to that of the prior configurations.
  • only two moveable die blades 421 are employed and they create a generally oval inside shape 422 with a corresponding generally oval and laterally elongated anvil 461.
  • a radius or fillet 423 is located at each upward edge of each die blade 421.
  • the punch may also be provided with an oval shaped leading end.
  • the clinching joint in the workpieces will be created with a laterally elongated and generally oval button and cup shapes for the interlocking joint.
  • a circular formation 462 coaxially projects from a backside of a flange 467 of the die.
  • a separate roll pin 469 longitudinally projects from a backside of formation 462 but in an offset position closer to a periphery thereof and not on the centerline of the die. The function of this offset pin will be discussed later.
  • FIG. 20 - 22 This embodiment of the present joining apparatus is essentially the same as all of the prior ones. Notwithstanding, the die assembly is different in that a lanced or partially pierced joint is formed between the workpieces and then the pierced edges are outwardly or laterally expanded after the partial piercing so as to overlap the pierced workpiece opening. But a separately installed fastener such as a rivet is not required.
  • Two die blades 521 are employed on either side of a laterally elongated anvil 561 which has flat lateral sides adjacent die blades 521 and curved ends spanning therebetween. Flexible elastomeric ring 521 or the coiled spring is employed to bias the die blades toward the anvil and allow for outward expansion thereof during joint forming.
  • a punch is similarly shaped to the anvil.
  • a centerline of pin 569 is parallel to the die bore.
  • Pin 569 fits within a matching hole in the C-frame.
