Abstract

PURPOSE:To provide a setting up method for a nut into plastic parts which is superior in productivity, by a method wherein a nut, whose tip is in a tapered state, outside diameter is slightly larger than the inside diameter of a setting hole and outside is notched into a knurl, is heated through high-frequency induction and pressing-in and adhesion are performed by softening an inner wall of the setting hole. CONSTITUTION:When a nut 3 is mounted into a setting hole 2, the same is held by a tapered surface and an axial line of the nut 3 and that of the setting hole 2 are coincident with each other. Then an induction coil 5 connected with a high-frequency oscillator 4 is put over the nut 3, for example, when an electric power of 900W at frequency of 1MHz is applied to the same, as the temperature of the surface of the nut 3 rises up to 230 deg.C about a second later and an inner wall of the setting hole 2 is softened by the heat, when the upper end of the nut is pressed, the nut is pressed in the inside of the setting hole 2 easily and setting-up is completed. When plastics is cured through cooling, as the plastic is made into a state wherein the plastics is intruded upon a knurl it does not happen that the nut 3 is come off from the setting hole 2 when a plastic case is assembled by screwing a bolt into the nut 3.

半割りとされ、一対の半割り片がボルトとナツトで固定
されることが多い。Plastic parts, such as plastic cases, have advantages such as high productivity in terms of quantity, and are therefore widely used as various cases. This plastic case is often split in half, and the pair of halves are often fixed together with bolts and nuts.

てしまう問題点がある。By the way, one method for inserting a nut into a plastic case is to set a nut in a mold during injection molding of the case, and fix it by a tight casting. However, when the case is large or large, the number of nuts increases, and it takes a lot of effort to set a large number of nuts in the mold, which hinders the advantage of injection molding, which is high productivity. Therefore, there is a problem that the operation rate of the injection molding machine decreases.

However, with this method, the heat applied to one end of the nut is conducted to the other end, softening the plastic. Because the nut is heated by conduction, it takes a long time to implant one nut. There is. Furthermore, if the heated iron accidentally comes into contact with the lip of the case, that part will melt and become a defective product.

It is something.

The tip of the nut has a tapered tip and an outer diameter slightly larger than the inner diameter of the implantation hole, and the outer surface is knurled.The nut is heated by high-frequency induction and the inner wall of the implantation hole is heated. It is characterized by being softened and then being pushed into a nut to make it stick.

The outer diameter of the tip is smaller than the inner diameter of the implant hole 2; the tip is tapered, and the outer diameter of the tip is smaller than the inner diameter of the implant hole 2. Therefore, when this nut 3 is placed in the planting hole 2, the nut 3 is held by the tapered surface and the axes of the nut 3 and the planting hole 20 are aligned, as shown in FIG. Next, when the induction coil 5 connected to the high frequency oscillator 4 is placed over the nut 3 and energized, a CAR wave current is induced on the outer surface of the nut 3, and the nut 3 is heated.

MHz is used, and when a 900W power was input at the frequency of IMH2 and applied to the entire area, the temperature of the surface of the nut 3 rose to 230°C after about 1 second. Since the inner wall of the planting hole 2 is softened by this MK, when the upper end of the nut 3 is pressed, it is easily pushed into the planting hole 2 and the planting is completed, but when the plastic hardens by cooling, the nut 3 is fixed. At this time, the plastic is stuck into the knurls on the surface of the nut 3 and solidified, so the connection is reliable. It will never fall below 2.

This method can raise the temperature in a short period of time, and can be used as a highly productive method for embedding nuts in plastic parts. It also eliminates the problem of accidentally melting and damaging plastic parts.
