Definitions

  • the present invention relates to weld beads and methods for vibration welding of thermoplastic joints through the use of weld beads.
  • vibration welding is frequently used to weld thermoplastic joints together.
  • vibration welding is conducted by vibrating two thermoplastic parts under pressure along a common interface to generate frictional heat and to thereby melt and fuse their surfaces together.
  • Vibration welding is a quick and inexpensive way to join irregularly shaped parts of various sizes.
  • vibration welding has been used in low load-bearing applications.
  • automobile underhood applications such as air intake manifolds, resonators, air filter housings
  • the expanded use of engineered plastics is desirable to achieve savings and weight and cost.
  • improvements in the welding techniques are necessary.
  • Welding results are extremely sensitive to significant changes in the weld process. Vibration welding parameters of pressure, frequency, amplitude, oscillation (welding) time, hold time, weld thickness, and surface contamination all affect tensile strength of welds. Weld beads assist in the welding process. Typically, a series of weld beads are formed on one or both of the abutting surfaces undergoing welding.
  • weld beads were uniform and continuously flat faced.
  • surface contamination on the weld beads (such as oil) inhibit the generation of frictional heat at the common interface whether the common interface is weld bead to weld bead or weld bead to weld face.
  • Time-consuming efforts have been used to control the level of contamination at these surfaces.
  • the invention involves a method of vibration welding thermoplastic surfaces together by using specially formed weld beads.
  • a plastic surface has at least one weld bead with an outermost portion smaller than the base of the weld bead. Due to the smaller area of the outermost portion, initial pressure is brought to bear on the surface contact during vibration welding than by using larger, uniform and conventional flat faced weld beads. Moreover, a lower level frictional force is required to commence the welding process given the smaller area of contact. As the welding process proceeds, the outermost portion melts down to the base of the weld bead and is then at full weld joint width.
  • the outermost portion of the weld bead has a texture.
  • This texture can take the form of a pattern such as a Crosshatch, knurl, or pebble pattern. Such a texture greatly improves the vibration welding of surfaces that have surface contamination such as oil.
  • the outermost contact area is a wedge.
  • This embodiment is particularly useful in the welding of the internal walls of a plastic body such as an air intake manifold or a plastic resonator. Due to the reduced force created at the point of contact by the specially designed and formed welding bead and the decreased frictional load required to commence the welding process, internal walls can easily be welded to the plastic body without the need to core out the body to accommodate welding fixtures. Greater design opportunities for plastic bodies such as manifolds or resonators are thus available.
  • all of the inventive embodiments have weld beads with an outermost portion of a smaller outer cross-section contact area, and which increases as the bead is consumed.
  • Some embodiments are wedge-shaped, while other embodiments are irregular surfaces. However, the embodiments all do include this feature.
  • Figure 1 shows a cross-sectional view of a weld bead as known in the prior art.
  • Figure 2 shows a weld bead in an embodiment of the present invention.
  • Figure 3 shows a weld bead in an embodiment of the present invention and its application to a hollow plastic body.
  • Figure 4 shows various embodiments of the present invention.
  • Figure 5 shows an embodiment of the present invention, a weld bead with a
  • Figure 6 shows an embodiment of the present invention, a weld bead with a knurl pattern.
  • Figure 7 shows an embodiment of the present invention, a weld bead with a pebble pattern.
  • FIG. 1 shows weld bead 20 with a uniform and continuously flat face as known in the prior art.
  • weld bead 20 has a height (shown here as 3.2 millimeters) and a base width (shown as 2.5 millimeters).
  • Flash traps 22 surround weld bead 20 and provide an area for the melting of weld bead 20 and the displacement of any surface debris. Flash trap 22 is shown having a depth of 1.7 millimeters and a width of 1.0 millimeter.
  • upper surface shell 26 is vibrated (at say 200 hertz) by a vibration welder, as commercially available.
  • the lower shell 24 remains stationary.
  • Shells 24 and 26 are most preferably part of an air intake system for vehicle engines.
  • Figure 2 shows an embodiment of the present invention.
  • Figure 2 illustrates the outermost portion of weld bead 120 in the shape of a wedge 30.
  • the cross-section of weld bead 120 includes first cross-section 32 at an outermost portion smaller than second cross-section 34 spaced into the weld bead 22.
  • Wedge 30 is shown with a height of 1.2 millimeters, a base width of 2 millimeters and a radius of 0.5 millimeters. Wedge 30 extends into flash trap 22 on lower shell 36.
  • the location of weld bead 120 could also be on the lower shell 36.
  • Trap 22 is shown with a width of 3.5 millimeters and a depth of 1.5 millimeters. Obviously, other configurations and sizes of both bead and trap can be used.
  • wedge 30 oscillates along the point of surface contact.
  • the very low initial contact area generates lower friction forces at the onset of the welding process.
  • molten plastic is produced, lowering vibration force loading.
  • the melting first cross-section 32 increases to the final meltdown distance, which is the design width 34 of the joint.
  • the Figure illustrates a good portion of the wedge crosshatched. Again, the crosshatched portion shows the original shape of the weld bead 30.
  • Wedge 30 is particularly useful in the vibration welding of the internal walls of hollow plastic bodies such as plastic manifolds and resonators.
  • An internal wall weld joint needs less width than a structural wall weld joint.
  • a smaller weld joint width provides sufficient sealing capability for an internal wall.
  • the load at the end of the welding process is lower than that of conventional weld beads 20. Since the amount of meltdown material is considerably less than that of conventional (flat) weld beads, the space required for a flash trap may be less as well.
  • relatively thin internal walls are possible without weld fixture support, allowing more design options and internal wall features.
  • FIG 3 shows another application of the present invention.
  • plural wedges 40 have been used to connect a hollow plastic body such as tuning tube 42 of a resonator to upper shell 44.
  • Tuning tube 42 is typically molded with very thin wall sections.
  • Wedges 40 allow for the vibration welding of tuning tube 16 to upper shell 44.
  • the low initial weld load and minimized overall weld bead width reduces the likelihood of any collapse of tuning tube 16.
  • Wedges 40 as shown, have a width of 1 millimeter at its base and a height of 1.5 millimeters.
  • wedges 40 spaced 0.67 millimeters apart, are shown.
  • One wedge 40 may also accomplish the welding. Obviously, other configurations and sizes can be used.
  • Figure 4 shows configurations 46 A, 46B, and 46C as differing wedge shapes.
  • 46A is a wedge of an included angle (here 45 degrees).
  • 46B is a wedge of an included angle (here 120 degrees).
  • the included angle may range from approximately 45 degrees to about 120 degrees.
  • the wedge may have a crown as shown in 46C.
  • Conventional weld bead 20 is shown as well.
  • Figure 5 shows the first cross-section 48 in the form of texture on weld beads
  • such texture has a depth ranging from approximately 0.0635 millimeters to about 0.254 millimeters with an included angle from approximately 4 degrees to about 10 degrees.
  • the texture consists of a Crosshatch pattern on weld bead 220 with a depth ranging from approximately 0.2 millimeters to about 0.5 millimeters.
  • the angle of the Crosshatch ranges from approximately 30 degrees to about 80 degrees in relation to the direction of vibration of weld bead 220.
  • Crosshatch pattern 48 is shown applied against weld bead 222.
  • Figure 6 shows the first cross-section 50A and 50B in the form of a knurl pattern on two opposing weld beads 52 and 54.
  • the pattern has a depth ranging from approximately 0.2 millimeters to about 0.5 millimeters.
  • the angle of the knurl ranges from approximately 30 degrees to 80 degrees in relation to the direction of vibration of weld beads.
  • weld bead 52 is applied against weld bead 54 and therefore pattern 50A is applied against pattern 50B.
  • Figure 7 shows the first cross-section 56 in the form of a pebble pattern on weld beads 58.
  • the pattern has a depth ranging from approximately 0.2 millimeters to about 0.5 millimeters. Pattern 56 is applied against pattern 56.
  • Figures 5, 6 and 7 are useful to reduce the affect of surface contamination such as oil on weld beads 20, 220, 52, 54, and 58. Specifically, the area of contamination is reduced to the initial contact areas of patterns 48, 50A, 50B and 56.
  • all of the inventive embodiments have weld beads with an outermost portion of a smaller cross-section contact area, and which increases as the bead is consumed.
  • Some embodiments are wedge-shaped, while Figure 5-7 embodiments are irregular surfaces. However, the embodiments all do include this feature.

Abstract

L'invention concerne un procédé de soudage par vibrations de surfaces thermoplastiques ensemble par l'utilisation de cordons de soudure formés spécialement. Dans un mode de réalisation décrit de cette invention, une surface plastique présente au moins un cordon de soudure (20) doté d'une partie extérieure (30) plus petite que la base du cordon de soudure. Du fait de la petite largeur de la partie extérieure, une pression supérieure est amenée à s'exercer sur le point de contact de la surface pendant le soudage par vibrations par rapport à l'utilisation de cordons de soudage à surfaces planes uniformes et classiques. De plus, une charge inférieure de chaleur de friction est requise pour entamer le processus de soudage étant donné que le point de contact est plus petit.
