４を加硫し、その後金型１、２より取り出した後、成型
滓のバリを取り除いて所望の軸受用密封材を得ていた。Conventionally, as shown in FIG. 1, a bearing sealing material is shown in FIG. 1. In a mold for molding the bearing sealing material, a core metal 3 of a reinforcing material is placed on a lower mold 2 and a synthetic rubber 4 is placed thereon. After supplying, closing the upper mold 1 and heating for a certain period of time to vulcanize the synthetic rubber 4, and then taking out from the molds 1 and 2, the burrs of the molding slag are removed to obtain a desired bearing sealing material. Was there.
このため、芯金の成型行程と密封材の成型行程は別行程

不良品の発生が起こり易く、その上一組みの金型から一
個づつ成型するので、一対の組みとなった金型を何個か
並べて一度に成型しても大量にしかも連続的に成型でき
ないから必然的にコスト高となり、さらに工程間のロス
か多いなどの欠点があった。For this reason, since the molding process of the core metal and the molding process of the sealing material are made in different processes, defective products are likely to occur due to mistaken insertion of the core metal or forgetting to insert them, and in addition, one mold is molded one by one. Therefore, even if several molds that were paired were arranged side by side and molded at the same time, it was not possible to mold a large amount and continuously, so the cost was inevitably high, and there was a drawback that there were many losses between processes. .
本発明はこれらの欠点を除去し、一度に大量の生産を可
能とした軸受用密封材を提供するものである。The present invention eliminates these drawbacks and provides a bearing sealing material that enables mass production at one time.

部８を設けたことを特徴とする軸受用密封材Ａである。The present invention will be described with reference to the drawings. As shown in FIG. 2, the bearing sealing material of the present invention includes a reinforcing member 5 such as a strip-shaped or flat metal plate, a synthetic resin plate, and a paper, a central hole 6a, and a central hole 6a. Center hole 6a
At least one connecting piece 7 connected to the reinforcing member 5 on the outside of the
Reinforcing member 5a of the bearing sealing material having at least one piece is punched out from outer peripheral hole 6b constituting the outer peripheral edge, and the punched reinforcing member 5 is formed.
After applying the adhesive to the elastic material, as shown in FIG.
10a is supplied, and this is baked or shaped with a pair of upper and lower molds 9a and 9b with the center hole 6a as a reference, and the sealing portion 10
After forming b continuously or in large numbers at a time, as shown in FIG. 5, the connecting piece 7 provided on the reinforcing member 5 having the seal portion 10b is cut off, and the sealant for bearing shown in FIG. A bearing sealing material for obtaining A, which is located on the sealing material side of the connecting piece 7 as shown in FIG. 3 and can be easily cut to a portion covered with a sealing portion 10b formed of an elastic material 10b. Is a sealing material A for bearings.

容易に切り離される脆弱部８を設けることにある。As shown in FIG. 3, an important point of the present invention is that the sealing member side of the connecting piece 7 is easily separated by pulling the outer peripheral side to a portion covered with the seal portion 10b of the elastic material 10a by an external force. It is to provide the fragile portion 8.

効果を低下せしめる心配は全くない。This point will be described in more detail. As shown in FIG. 2, the fragile portion 8 is a range in which the connecting piece 7 is not cut at the same time when the center hole 6a, the outer peripheral hole 6b and the small hole 6c are punched out. Since a cut is made at the depth or width of to obtain the fragile portion 8,
It can be easily provided without requiring a special cutting process. In this way, the reinforcing member 5 having a fragile portion 8 on the connecting piece 7 and having the central hole 6a, the outer peripheral hole 6b, etc. punched out is strip-shaped or flat-plate-shaped.
After the adhesive is applied, the seal portion 10b is formed by the elastic material 10a by the pair of upper and lower molds 9a and 9b as shown in FIG. The reinforcing member 5a having the seal portion 10b is formed,
As shown in FIG. 5, the portion that becomes the bearing sealant A is sandwiched and held by the punch 14 and the cushion 15, and the unnecessary portion, that is, the reinforcing member 5 and the burr 11 that are removed are sandwiched by the holding metal fitting 12 and the die 13 and are positioned vertically. By shifting, the fragile portion 8 of the connecting piece 7 is torn off, and the bearing sealing material A is reinforced.
As shown in FIG. 6, the holes are separated from each other to leave a small hole outward from the fragile portion 8. However, the reinforcing core material 5a is the same as the core metal of the conventional sealing material. There is no concern that the sealing effect at the outer peripheral portion will be reduced by being covered with the seal portion 10b of the body material 10a.
また、不要部分と共に一緒に捨てられ、軸受用密封材Ａ
のバリ取りも同時に行われるので、連続作業を容易に
し、大量の生産を可能とするものである。In addition, the bearing sealing material A is discarded together with unnecessary parts.
Since deburring is also performed at the same time, continuous work is facilitated and mass production is possible.

明を限定するものではない。As described above, the bearing sealing material A of the present invention is formed by combining the punching step, the adhesive applying step, the step of supplying the elastic material, the seal part forming step, and the separating step through the reinforcing member 5. The bearing sealing material A may be obtained continuously or in large numbers at a time, but the molding method performed in the same step does not limit the present invention.

給できれば良いので特に限定しない。That is, in the punching step and the weakened portion 8 forming step, a large number of flat plate-shaped reinforcing members 5 are punched at once, or the strip-shaped reinforcing members 5 are continuously punched, and at the same time or after the weakened portions are formed. 8 may be formed, and its shape may be bent or slitted on the inner and outer peripheral edges after punching. Next, the method of applying the adhesive is not limited to any method as long as it is a known method such as spray coating, roller coating, or coating through a bath. Further, even in the step of supplying the elastic material 10 to the mold, a method such as simply stacking flat plate-shaped materials, shaped materials to which molding is added in advance or various shapes, or injection supply is conceivable, Any one of them is not particularly limited as long as an appropriate amount can be supplied to the shaping portions of all the sealing portions 10b of the reinforcing member 5.

用密封材を低コストで得ることができる。As described above, according to the present invention, in the bearing sealing material, a series of multiple steps from core metal molding to seal part 10b molding to separation finishing processing are performed with a multi-cavity metal plate, so loss between processes and misalignment of core metal Also, it is possible to prevent improper charging, to shorten the molding time without time loss and to improve the productivity, and also to prevent the sealing effect from being lowered by projecting one end of the reinforcing member in the outer peripheral direction of the bearing sealing material A. Thus, it is possible to obtain a bearing sealant having excellent sealability equivalent to that of the conventional bearing sealant at low cost.
