Abstract

PURPOSE:To perform the formation of a friction material and the bonding of the back metal in a short time, without using the degassing process, by applying an adhesive to the upper surface of a back metal, setting the metal to the bottom of a mold, charging a powdery friction material to the mold, preheating with ultrasonic vibration, and applying a high pressure with a vibration horn. CONSTITUTION:For example, the back metal 4 coated with the adhesive 3 is placed on the bed 2 at the bottom of the mold 1, and the powdery friction material 5 is charged into the mold 1. The frictional material 5 is preheated by pressing down the ultrasonic vibrator 7 energized with the ultrasonic generator 6 along the direction of the arrow A. Thereafter the ultrasonic vibrator 7 is further pressed down to apply a high pressure to the friction material 5 with the vibration horn 8. The formation of the friction material and the bonding of the back metal can be carried out at the same time.

Description

【発明の詳細な説明】 本発明は摩１察′４Δの成形と同時に痕金の接着を行な
う方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for bonding metal traces at the same time as forming a metal plate.

従来広く採用されている摩擦ｊＡ　；Ｉｔ成形法は、金

１を熱成形用金型に投入し、加圧成形する方法である。In the conventionally widely used friction forming method, after heating the mold to the required temperature, the preformed friction material raw material 3
1 is put into a thermoforming mold and press-molded.

必要とする等の欠点がある。In this molding method, the curing of the friction product starts from the outside, so a process to remove the reaction gas is required.Furthermore, the friction material, which has poor heat conductivity, is heated from the outside, so molding takes a long time, and the mold There are drawbacks such as the need for extra energy to heat the

接着を行なう方法に関づるものである。The present invention has been made in order to eliminate such drawbacks, and a backing metal whose upper surface has been treated with an adhesive in advance is attached to the bottom of the molding die, and then the powdered friction material is attached to the backing metal. In order to shorten the molding time, the friction 'JIA' is preheated by ultrasonic vibration for a short period of time (for example, several seconds) as a pre-process, and then the friction is heated using an ultrasonic horn. This relates to a method of applying high pressure to the material or applying high pressure using a separate hot press to simultaneously form the friction material and bond the backing metal.

ため、その後の加圧成形の工程ではガス１友きの必要が
なく、短時間で成形することかできる。また裏金の接着
は粉末原オ′４と直接接着するので合理的である。According to the method of the present invention, residues such as moisture and reaction gas are removed from the powder raw material during preheating by short-term ultrasonic vibration, so it is necessary to use one gas in the subsequent pressure molding process. There is no molding, and molding can be carried out in a short time.Furthermore, the bonding of the backing metal is rational because it is directly bonded to the powder raw material O'4.

以下に本発明を図面に示す実施例によって説明する。The present invention will be explained below with reference to embodiments shown in the drawings.

After setting 1) the next friction month 5 in the mold 1, press down the ultrasonic vibrator 7 which activated the ultrasonic vibrator 6 in the direction of arrow A to +4El 1' 315 is preheated by applying ultrasonic vibration. After the preheating is completed, the ultrasonic vibrator 7 is further pushed down and high pressure is applied to the friction material 5 by the vibrating wheel 8 to form it. In addition, in order to cause a sufficient reaction of the resin component in this molding, a more sufficient adhesive strength of the backing metal can be increased by 1q by applying tightening pressure and heating during after-curing to cause a sufficient reaction of the resin component.

。Next, we will discuss the case where the friction material 1 is preheated by ultrasonic vibration and then pressure-formed by a hot press.As shown in FIG. After setting the back metal 4 coated with adhesive 3 on the stand 2 and loading the powdered friction material 15 into the mold 1, the ultrasonic vibrator 6 is activated -u and the ultrasonic vibrator 7 is moved in the direction of arrow A. The friction material 5 is pressed down in the direction and ultrasonic imaging is applied to the friction material 5 to preheat it. However, in this case, a heater 9 is installed inside the mold 1 and the pedestal 2, and by heating them to a predetermined temperature, preheating of the friction material is assisted. The mold 1 and the pedestal 2 containing the abrasive material 5 and the back metal 4 preheated in a few seconds in this way are moved to the pressurizing process shown in FIG. 3.

れる。The method of simply press-forming with a hydraulic press after heating the friction material by ultrasonic vibration has the drawback that the vibration conditions vary depending on the composition of the 4Δ material, and the specific gravity and hardness of the product are relatively small. However, this method of the present invention does not have such problems, and in addition to the above-mentioned advantages, it is relatively easy to mold thick or large objects, and there are fewer difficulties in molding depending on the material (resin, etc.). Moreover, 1q of products with stable quality can be obtained.
