Cut it right.
次に、上記素材6の一端部をネジの外径に相当する径に
切削加工し、直巌部7と前記基礎部iとを形成する(第
2図B)。Next, one end of the material 6 is cut to a diameter corresponding to the outer diameter of the screw to form the straight part 7 and the base part i (FIG. 2B).
つづいて、上記切削加工した直線部7の外周に機械加工
またけ転造方法により前記ネジ部5を形成し、前記アン
カボルト1を得る(第2図C)。Subsequently, the threaded portion 5 is formed on the outer periphery of the cut straight portion 7 by a machining and rolling method to obtain the anchor bolt 1 (FIG. 2C).
しかしながら、かかる従来の製造方法にあっては、制価
な異形丸棒を素材と1−て使用し、かつ切削加工やネジ
加工を施しているため、工程が多く、しかも手間のかか
る機械加工の工程があるので流れ作業に適さず工数が増
大し、コストが高いという問題点があった。However, in such conventional manufacturing methods, an expensive irregularly shaped round bar is used as the raw material, and cutting and threading are performed, so there are many steps and labor-intensive machining is required. Since there are steps involved, it is not suitable for assembly-line work, increases the number of man-hours, and has the problem of high costs.
本発明は、かかる従来の実情に鑑みてなされたものであ
って、安価な素材を用い、かつ工数低減した加工方法を
採ることにより、製造容易でかつコストの安いアンカボ
ルトの製造方法を徒供することを目的とする。The present invention has been made in view of such conventional circumstances, and provides a method for manufacturing anchor bolts that is easy to manufacture and inexpensive by using inexpensive materials and using a processing method that reduces the number of man-hours. The purpose is to
以下、図面に基づいて本発明の一実施例について詳述す
る。Hereinafter, one embodiment of the present invention will be described in detail based on the drawings.
第3図は、本発明方法により製造されたアンカボルト1
1を示し、一端外周面に凹凸である凹凸模様12が形成
された基礎部13と、他端外周面にネジ14が形成され
たネジ部15と、中央外周面が平滑未加工の捷まの直線
部16とからなる。FIG. 3 shows an anchor bolt 1 manufactured by the method of the present invention.
1, the base part 13 has an uneven pattern 12 formed on the outer peripheral surface of one end, the threaded part 15 has a screw 14 formed on the outer peripheral surface of the other end, and the unprocessed unfinished part has a smooth outer peripheral surface at the center. It consists of a straight section 16.
このアンカボルト11は、例えば第4図に示すような工
程を経て製造することができる。This anchor bolt 11 can be manufactured through the steps shown in FIG. 4, for example.
即ち、まず第4図Aに示すように、外周面が平滑でかつ
所定のネジの有効径に相当する外径の丸棒を素材17と
して用い、所定長さに切断する。That is, first, as shown in FIG. 4A, a round bar with a smooth outer circumferential surface and an outer diameter corresponding to the effective diameter of a predetermined screw is used as the material 17 and cut into a predetermined length.
次に、上記素材17の一端外周面に転造方法により所定
のネジ14を加工しネジ部15を形成する(第4図B)
。Next, a predetermined screw 14 is machined on the outer circumferential surface of one end of the material 17 by a rolling method to form a threaded portion 15 (FIG. 4B).
.
つづいて、上記素材17の他端外周面に転造方法により
所定の凹凸模様12を加工し基礎部13を形成し、かつ
該基礎部13と上記ネジ部15との間に未加工のままの
直線部16を有する前記アンカボルト11ヲ得7る(第
4図C)。Next, a predetermined uneven pattern 12 is formed on the outer peripheral surface of the other end of the material 17 by a rolling method to form a base part 13, and an unprocessed part is formed between the base part 13 and the threaded part 15. The anchor bolt 11 has a straight portion 16 (FIG. 4C).
邑
尚、上記基礎部13とネジ15は、上記実施例と逆の順
序で力ロエすることもでき、また同時に加工することも
可能であり、この場合にはより工数が削減される効果が
ある。In addition, the base portion 13 and the screw 15 can be machined in the reverse order of the above embodiment, or they can be machined at the same time. In this case, the number of man-hours can be further reduced.
本発明は、上記のような製造方法としたので、次のよう
な効果がある。Since the present invention employs the manufacturing method as described above, it has the following effects.
0)素材として異形丸棒を用いることなく、普通の丸棒
を用いることができ、しかも外径はネジの有径分の太さ
があればよいので、従来より小径の丸棒でよく、素材の
コストが安価となる。0) An ordinary round rod can be used as the material without using an irregularly shaped round rod, and the outer diameter only needs to be as thick as the diameter of the screw, so a round rod with a smaller diameter than before can be used, and the material The cost will be low.
e)異形丸棒を素材として使用した場合のようにネジを
加工するための前加工として外周面を小径に切削加工す
る機械加工工程が不要となるので、工数が少なくなる。e) The number of man-hours is reduced because the machining process of cutting the outer circumferential surface to a small diameter as a pre-processing for machining a screw, which is required when a deformed round bar is used as a raw material, is no longer necessary.
G)素材に対する加工は、切断加工と転造加工のみでよ
いので、流れ作業に好適であり、工数が大幅に減少し、
〃ロエコストが者しく安価となる。G) Since only cutting and rolling are required for processing the material, it is suitable for assembly work, and the number of man-hours is significantly reduced.
〃Loe cost becomes significantly cheaper.
