確実に盛金させる方法及び装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and an apparatus for reliably depositing stellite or other metal-plating material in the form of pellets onto a limited portion of a base material by the positioning action of a holding means.

従来、金属台材上に盛金をつくる方法は、特公−昭３７
−２１６４号公報により公知である。Conventionally, the method of making gold on a metal base was
It is publicly known from the publication No.-2164.

この方法は、金属粉末を容器内に入れ、これを金属台材

金属管（以後盛金材と呼ふ）を供給手段により落すと、
盛金材は切込溝内において安定するため、盛金材を加熱
溶融させて盛金材の自動供給によつても台材に盛金する
ことが可能である。In this method, metal powder is placed in a container, placed on a metal base, and the entire container is melted and deposited onto the base. Therefore, in this method, if the base material is a metal bar and cut grooves are provided on the outer circumference at equal intervals in the axial direction of the bar, the cut grooves are filled with metal powder. When the metal pipe (hereinafter referred to as metal filling material) is dropped by the supply means,
Since the overlay material is stable within the cut groove, it is possible to overlay the base material by heating and melting the overlay material and automatically supplying the overlay material.

により盛金を行うことは不可能であつた。However, when the base material is a thin plate, a thin rod, or has dot-like metal parts, when the metal material is dropped onto the part to be metallized using the feeding means, it will bounce off and fall outside. Since the metal does not touch the part to be deposited, it has been impossible to automatically supply the deposit material to a thin plate, a thin rod, or a base material having dotted deposit portions.

材２６を盛金するのにも好適なものである。As shown in the embodiment, when depositing metal onto the saw tooth a of the saw 8, the main body 1 is tilted forward as shown in FIG. Or, set it so that it is slightly tilted forward, and when the filler material 26 is melted on the filler part a'', it tends to move toward the cutting edge side,
When the cams 15 and 23 are rotated by the reducer motor 14, the cam 23 pushes up the open cam rod 21, and the metal filling material 26
At the same time, the cam 15 drives the feeder 10 to send the saw 8 so that the metal part a' of one saw tooth a reaches the position of the metal material holding means 16, and then retreats. , the opening cam rod 21 is lowered and the holding means 1 is
6 is closed to enclose the filling part y, the extrusion rod 30 in the feeding means F for the filling material 26 moves forward and drops one pellet filling material 26, which is being sent to the delivery tube 27, into the filling part y. , the filler material 26 is positioned on the filler part j by the holding means 16 and stabilized, and the heating means 34 is fed out by the cylinder 35 or the like, heats the filler material 26, and becomes the filler material a.
”. At this time, the open cam rod 21 or the filler material 26
When the holding means 16 is opened, the feeder 10 or the saw 8 is sent so that the filler part y of the next saw tooth a reaches the position of the holding means 16 of the filler material 26, and as a result, the holding means 16 is closed and the filler is removed. When the metal part j is surrounded, this feeding means F of the metal material 26 is surrounded by the metal part y.
When the filler material 26 is dropped and positioned by the holding means 16, the heating means 34 performs an operation of welding the filler material 26 to the sawtooth a, so that the filler material 26 is automatically supplied to the filler portion a'' of each sawtooth a of the saw 8. The operation for depositing the deposit can be carried out automatically without requiring any human intervention, and the amount of deposit is controlled by the holding means 1 because the deposit material 26 is made into pellets.
Since the positions are accurately aligned by the positioning method 6, the subsequent final polishing can be carried out extremely easily. As shown in the above embodiments, the pellet-type metal filling method and device according to the present invention can not only be used for metal filling on the saw teeth a of the saw 8 or the blades of cutters and other blades, but also can be used for high-speed metal filling. It is also suitable for locally depositing the deposit material 26, which increases strength and wear resistance, on severely worn parts of various mechanical parts that undergo repeated mechanical contact and friction.

な省力化と、能率増進とを計ることができる。As mentioned above, the pellet-type metal filling method according to the present invention involves feeding a necessary amount of pelletized metal material into the metal holding means that surrounds the metal forming part of the base material by a supplying means, and depositing the metal metal material by this means. This is because the metal is aligned and stabilized in the area where the metal should be applied, and then heated and welded to the base material.
Even if the filling material is automatically supplied by the feeding means, the filling material can be correctly positioned to the thin plate, thin rod, or dot-shaped filling part and the filling can be performed fully automatically, making it possible to complete the filling work completely. It is possible to measure labor saving and efficiency improvement.

。Since the metal filling material is made into pellets, if the amount of the metal filling material is set according to the metal forming part, the amount of metal filling material can be kept uniform and appropriate at all times, and expensive stellite and other metal filling materials are not wasted. Since the filling part is surrounded by the holding means for the filling material, if the holding means determines the position of the filling material and further regulates the melting form, the position and shape of the filling material are almost aligned, and slight finishing polishing can be performed. Since the product can be made into the correct shape and dimensions with just one tool, the product is highly accurate, there is less wear on the grinding wheel, and finishing time is shortened.
