刻する。 Conventionally, in the production of keys whose heads are molded from resin, as shown in the process diagram in Figure 1, a semi-finished key is first made by press punching from a plate, and then the key shaft part of this semi-finished product is cut. Alternatively, a keyway is formed by press working, and then a ridge is processed by a ridge processing device and a key number is stamped.

ていた。 After barrel processing, plating with nickel or the like is performed, and then the key head is molded with resin, and then, for example, 3
A key with a resin head was created by combining several keys together and binding them into a bundle with a ring.

番号を付したキー毎にまとめて、これらをリング
により束ねる必要があつた。 As mentioned above, in the conventional process, the keys that are carved and given key numbers become separated when entering the barrel process or the plating process, and the keys with the same number become separated, and the keys that are given key numbers are separated during the plating process. After that, it was necessary to group the keys whose heads were molded with resin into each key with the same number, and to bundle them with a ring.
しかし、離散した多数のキーにの中から同一番

にとつて煩雑であり作業性が悪くなるという問題
があつた。 However, the task of collecting and linking keys with the same number from among a large number of discrete keys is troublesome for the operator, and there is a problem in that the work efficiency is degraded.

ーの製造方法を提供することを目的とする。 This invention was made to solve the above problem, and after molding the key head with a key number with resin, immediately bundle the keys with the same number with a ring and then plate them. It is an object of the present invention to provide a key manufacturing method that can improve productivity by facilitating the work of bundling keys of the same number with a ring.
以下、この発明の実施例を第２図の工程図によ

するもである。 Hereinafter, an embodiment of the present invention will be explained with reference to the process diagram of Fig. 2. First, the key manufactured here has a head molded with resin as shown in Fig. 3, and for example, three keys with the same number are formed. It is completed by being tied together with a ring.

が打刻される。 First, a semi-finished key is made by stamping a brass or iron plate. Then, a keyway (groove) is formed in the key yank portion of this semi-finished product by cutting or press working, and a keyway is processed by a threading machine, and a key number is stamped on the key.

集められ、金属製のリングにより束ねられる。 Next, the key head 2 is formed by molding a resin, but this resin is made of vinyl chloride, vinylidene chloride, polyethylene, trifluoride or tetrafluoride, so as not to be affected by the subsequent plating process. Alkali-resistant and acid-resistant resins, such as ethylene chloride, are used. Then, the keys whose heads are molded in resin proceed to the next process in order without falling apart, and the three keys with the same code are easily gathered together and bound together with a metal ring. .

部分のみがめつき処理され、キーが完成する。 Next, the three linked keys are put into a barrel machine to remove surface burrs, and then put into a plating process. In the plating process, for example, ordinary nickel plating is applied to the key yank part 1 of the metal part, but the degreasing, pickling, plating, and neutralization treatments during this time do not affect the resin at all, and the resin Only the metal surface portion is plated without deforming or discoloring the head 2, and the key is completed.

Nickel plating was performed for 60 minutes using 30 g/H 3 BO 3 , followed by neutralization for 0.5 minutes with a solution of 30 g/Na 2 CO 3 , and the resin head of the key was Vinyl chloride, metal parts are copper alloy.

（リンキング）を防止することができる。 As described above, according to the key manufacturing method according to the present invention, a keyway is formed on a semi-finished key, a key ridge is processed, and the head of the key is molded with resin, and then keys of the same number are combined into one key. Because it is configured to bundle and plate the bundled keys,
During the plating process, keys with the same number are not scattered and the same keys can be easily linked, which improves workability and productivity compared to conventional methods. Mixing (linking) of different keys can be prevented.

ても、樹脂部とキー頭部との間の結合が弱くなる
という不具合は生じない。 In addition, since plating is performed after resin molding, unnecessary plating of resin molded parts is not performed, which is economical. Therefore, even if there is poor plating such as poor adhesion in the plating layer, the problem of weakening of the bond between the resin part and the key head does not occur.
また、樹脂成形したキーをめつきするため、め

止することができる。 Furthermore, since the resin-molded key is plated, metals are less likely to stick together in the plating bath, and it is possible to prevent poor plating due to adhesion of plated objects to each other.
