Description
【０００１】[0001]
この考案は、建設工事現場において鋼板等に金具を接続するため、鋼板等に打 込む鋲打銃用ボルトピンに関するものである。 The present invention relates to a bolt pin for a rivet gun driven into a steel plate or the like for connecting a metal plate to the steel plate or the like at a construction site.
【０００２】[0002]
建設工事現場においては鋼板等に金具を接続するために、鋲打銃でボルトピン を鋼板等に打込み、ボルトピンの雄ねじ部を利用して金具を接続することが行わ れている。 At the construction site, in order to connect metal fittings to steel plates, etc., bolt pins are driven into the steel plates with a rivet gun and the metal fittings are connected using the male threads of the bolt pins.
【０００３】 このような場合に従来から使用されている鋲打銃用ボルトピン１の一例を図６ によって説明すると、尖鋭になっている先端２側は打込部３になっており、基端 ４側は打込部３よりも大径に作られていて、大径に作られている基端４側の周囲 には雄ねじ部５が形成されている。An example of a bolt pin 1 for a rivet gun conventionally used in such a case will be described with reference to FIG. 6, in which the sharpened tip 2 side is a driving portion 3 and a base end 4 The side is made larger in diameter than the driving part 3, and a male screw part 5 is formed around the base end 4 side which is made large in diameter.
【０００４】 打込部３の周囲には、図７の断面図にも示すように、長手方向に凹凸のローレ ット６が形成されている。このローレット６の凹凸の高さは、打込部３の全長に 亘って同じ高さの形状になっている。As shown in the cross-sectional view of FIG. 7, a knurling 6 having irregularities in the longitudinal direction is formed around the driving portion 3. The height of the unevenness of the knurl 6 has the same height over the entire length of the driving part 3.
【０００５】 この鋲打銃用ボルトピン１を用いて鋼板に金具を接続する場合には、図示しな い鋲打銃を用いて図８に示すように鋲打銃用ボルトピン１の尖鋭になっている先 端２を鋼板７に打ち込むと、ローレット６の部分が鋼板７の中に入り込み、鋼板 ７の収縮による締付圧力がローレット６に加わって、鋲打銃用ボルトピン１は鋼 板７から抜けなくなる。When a metal fitting is connected to a steel plate by using the stud hammer bolt pin 1, a stud gun not shown is used to sharpen the stud gun bolt pin 1 as shown in FIG. When the tip end 2 is driven into the steel plate 7, the part of the knurl 6 enters into the steel plate 7, and the tightening pressure due to the contraction of the steel plate 7 is applied to the knurl 6, and the bolt pin 1 for the rivet gun comes out of the steel plate 7. Disappear.
【０００６】 次に一端側の内面に雌ねじ８が刻設されている接続金具９の雌ねじ８を鋲打銃 用ボルトピン１の雄ねじ部５に螺合して接続金具９を接続し、接続金具９他端の 雌ねじに雄ねじ杆１０を螺合していた。Next, the female screw 8 of the connecting metal fitting 9 having the female screw 8 engraved on the inner surface on one end side is screwed into the male screw part 5 of the bolt pin 1 for a rivet gun to connect the connecting metal fitting 9, and the connecting metal fitting 9 The male screw rod 10 was screwed into the female screw at the other end.
【０００７】[0007]
鋲打銃用ボルトピン１の打込部３周囲のローレット６の凹凸を形成する際には 、凹部になる箇所に成型ロール等で圧力を加えて凹ませ、これによる塑性変形に よって凸部を形成しているため、ローレット６の部分や基端４側のローレット終 端部１１に歪みによる内部応力が発生していて、鋲打銃用ボルトピン１を鋼板７ に打込んだ時や、接続金具９及び雄ねじ杆１０に引抜き力がかかった際に、鋲打 銃用ボルトピン１がローレット６の部分やローレット終端部１１で破断する場合 があった。 When forming the unevenness of the knurling 6 around the driving part 3 of the bolt pin 1 for a rivet gun, pressure is applied to the concave part by a pressure such as a molding roll, and the convex part is formed by the plastic deformation. Therefore, internal stress due to strain is generated in the knurled portion 6 and the knurled end portion 11 on the proximal end 4 side, and when the bolt pin 1 for the rivet gun is driven into the steel plate 7 or the connecting fitting 9 In addition, when the pulling force is applied to the male screw rod 10, the bolt pin 1 for the hammer may break at the knurl 6 portion or the knurl end portion 11.
【０００８】 この考案はこのような従来の欠点を除去し、ローレットの部分やローレット終 端部で破断しないようにした鋲打銃用ボルトピンを提供することを目的とするも のである。It is an object of the present invention to provide a bolt pin for a rivet gun that eliminates the above-mentioned conventional drawbacks and does not break at the knurl portion or the knurl end.
【０００９】[0009]
この考案の鋲打銃用ボルトピンは、先端側に打込部を、基端側に雄ねじ部を備 え、前記打込部の周囲に、先端側が高く基端側に向かうに従って次第に高さが低 くなる形状の長手方向のローレットを形成したことを特徴とするものである。 The bolt pin for a rivet gun of the present invention has a driving portion on the tip end side and a male screw portion on the base end side, and the tip end is high and the height gradually decreases toward the base end around the drive portion. It is characterized in that a knurl in the longitudinal direction having a curved shape is formed.
【００１０】[0010]
打込部の周囲に長手方向に形成してあるローレットが、先端側が高く基端側に 向かうに従って次第に高さが低くなっているので、ローレットの部分やローレッ ト終端部１１に、歪みによる内部応力が分散されて集中しなくなる。 The knurling that is formed in the longitudinal direction around the driving part is higher on the tip side and gradually lowers toward the basal side. Therefore, internal stress due to strain is applied to the knurled part and the knurling terminal part 11. Are dispersed and not concentrated.
【００１１】[0011]
次に、この考案の実施例を説明する。 Next, an embodiment of this invention will be described.
【００１２】 図１はこの考案の一実施例の側面図であって、この考案による鋲打銃用ボルト ピン２０も従来のものと同様に、尖鋭になっている先端２１側は打込部２２にな っており、基端２３側は打込部２２よりも大径に作られていて、大径に作られて いる基端２３側の周囲には雄ねじ部２４が形成されている。FIG. 1 is a side view of an embodiment of the present invention. A bolt pin 20 for a rivet driving gun according to the present invention is similar to the conventional one, and a sharpened tip 21 side has a driving portion 22. The diameter of the base end 23 side is larger than that of the driving portion 22, and a male screw portion 24 is formed around the base end 23 side having the large diameter.
【００１３】 打込部２２の周囲には、長手方向に凹凸のローレット２５が形成されている。 このローレット２５は従来のような全長に亘って同じ高さの形状ではなく、先端 ２１側が図２に示すように凹凸の高さが高く、基端２３側に向かうに従って、図 ３、図４に示すように凹凸の高さが次第に低くなる形状に作られていて、ローレ ット終端部２６では自然にローレット２５がなくなるようになっている。A knurl 25 having irregularities in the longitudinal direction is formed around the driving part 22. This knurl 25 does not have the same height over the entire length as in the conventional case, but the tip 21 side has high unevenness as shown in FIG. As shown, the height of the unevenness is gradually reduced, and the knurl 25 is naturally eliminated at the knurl end portion 26.
【００１４】 この鋲打銃用ボルトピン２０を用いて鋼板に金具を接続する場合には、従来と 同様に図示しない鋲打銃を用いて図５に示すように鋲打銃用ボルトピン２０の尖 鋭になっている先端２１を鋼板７に打ち込むと、ローレット２５の部分が鋼板７ の中に入り込み、鋼板７の収縮による締付圧力がローレット２５に加わる。打込 部２２の周囲に形成されているローレット２５は先端２１側が凹凸の高さが高く 、基端２３側に向かうに従って凹凸の高さが次第に低くなる形状に作られている ため、鋼板７に打ち込まれて鋼板７の収縮による締付圧力が加わっているローレ ット２５の部分が鋼板７に対して楔の効力を発揮し、鋲打銃用ボルトピン２０は 鋼板７から抜けなくなる。When a metal fitting is connected to a steel plate using the stud hammer bolt pin 20, a stud hammer (not shown) is used to sharpen the stud gun bolt pin 20 as shown in FIG. When the tip 21 of the shape is driven into the steel plate 7, the portion of the knurl 25 enters the steel plate 7, and the tightening pressure due to the contraction of the steel plate 7 is applied to the knurl 25. The knurl 25 formed around the driving portion 22 has a shape in which the height of the unevenness is high on the distal end 21 side and gradually decreases toward the base end 23 side. The portion of the knurling 25 that has been driven in and is given a tightening pressure due to the contraction of the steel plate 7 exerts a wedge effect on the steel plate 7, and the bolt pin 20 for the rivet gun cannot come off from the steel plate 7.
【００１５】 次に一端側の内面に雌ねじ８が刻設されている接続金具９の雌ねじ８を鋲打銃 用ボルトピン２０の雄ねじ部２４に螺合して接続金具９を接続し、接続金具９他 端の雌ねじに雄ねじ杆１０を螺合する。Next, the female screw 8 of the connecting metal fitting 9 having the female screw 8 engraved on the inner surface on one end side is screwed into the male screw part 24 of the bolt pin 20 for the rivet gun to connect the connecting metal fitting 9, and the connecting metal fitting 9 The male screw rod 10 is screwed into the female screw at the other end.
【００１６】[0016]
この考案は、打込部２２の周囲に形成してあるローレット２５が、先端２１側 が高く基端２３側に向かうに従って高さが次第に低くなる形状に作られているの で、凹部になる箇所に成型ロール等で圧力を加えて凹ませ、これによる塑性変形 によって凸部を形成した際の歪みによる内部応力が基端２３側に向かうに従って 漸減し、ローレット２５の部分やローレット終端部２６での鋲打銃用ボルトピン ２０の破断が無くなって、安定した強度が得られる効果がある。 According to this invention, the knurl 25 formed around the driving portion 22 is formed in a shape in which the tip 21 side is high and the height is gradually lowered toward the base end 23 side. Internal stress due to strain when the convex portion is formed by plastic deformation due to the pressure is applied to the knuckle by a molding roll or the like, and gradually decreases toward the base end 23 side. The bolt pin 20 for the rivet gun is not broken, and stable strength can be obtained.
【００１７】 またローレット２５が、先端２１側が高く基端２３側に向かうに従って高さが 次第に低くなる形状に作られているので、鋼板７に打ち込んだ鋲打銃用ボルトピ ン２０は抜けにくく強固に固定され、鋼板７から露出している部分のローレット ２５の凹凸の高さを見て、鋼板７に対する打込部２２の打込み深さを判断できる 効果がある。Further, since the knurl 25 is formed in a shape in which the tip 21 side is high and the height is gradually lowered toward the base end 23 side, the tack pin bolt pin 20 driven into the steel plate 7 is hard to come off and is solid. There is an effect that the driving depth of the driving portion 22 with respect to the steel plate 7 can be determined by observing the height of the irregularities of the knurls 25 that are fixed and exposed from the steel plate 7.
