Description

本発明は、自動車のボンネットやドアの開閉ロック装置における一部品として用いられるストライカーに関する。  The present invention relates to a striker used as one part in an automobile hood or door opening / closing lock device.

技術背景Technical background

従来、この種ストライカーは、例えば図13,図14に示すように、両端部に固定ボルト用の貫通孔10a,10aを有し、かつ中央上下部にカシメ孔をもつ鋼製の取付座板10と、鋼製の丸棒をその両端部が取付座板10のカシメ孔に一致するようにU字状に屈曲成形され、かつ各端部に鍔部11a,11aをもつ係合杆11とからなり、取付座板10のカシメ孔に加熱した係合杆11の両端部を差し込み、取付座板10の裏側からその差し込み先端部をカシメ止めして両者を結合するようになされている。  Conventionally, this type of striker has, as shown in FIGS. 13 and 14, for example, a steel mounting seat 10 having through holes 10a and 10a for fixing bolts at both ends and caulking holes at the center upper and lower parts. And an engagement rod 11 having a round bar made of steel bent into a U shape so that both ends thereof coincide with the caulking holes of the mounting seat plate 10 and having flanges 11a and 11a at each end. Thus, both ends of the heated engagement rod 11 are inserted into the caulking holes of the mounting seat plate 10, and the insertion tip portion is caulked from the back side of the mounting seat plate 10 to couple them together.

そして、このストライカーはボンネットの裏側のベース部材や、ドアと対向する車体側の剛性フレームの側面などに取付座板10の貫通孔10a,10aに挿入される一対の固定ボルト(図示せず)により螺着されて用いられる。  The striker is formed by a pair of fixing bolts (not shown) inserted into the through holes 10a and 10a of the mounting seat plate 10 on the base member on the back side of the bonnet, the side surface of the rigid frame on the vehicle body side facing the door, and the like.

図5〜11は、本発明のストライカーの製造工程を示すもので、多段式圧造成形機(図示せず)による複数の圧造工程で、まず、1個のブランクAから両端部に固定ボルト用の貫通孔2a,2aを有する取付座部2と、取付座部2の中央部から前方に突出し、かつ、係合孔を持たない側面視形状が四角形状の予備係合部(方形状下部F2)とを一体成形してなる中間成形体(第5成形体F)を段階的に形成し、その後、最終工程で中間成形体の予備係合部を側面方向からその中心部分を四角形状に打ち抜いて係合孔3aを形成し、側面視形状が四角形状の係合部3を形成したものである。  FIGS. 5-11 show the manufacturing process of the striker of the present invention. In a plurality of forging processes by a multi-stage forging machine (not shown), first, one blank A is used for fixing bolts at both ends. A mounting seat portion 2 having through holes 2a, 2a, and a pre-engagement portion projecting forward from the center portion of the mounting seat portion 2 and having a rectangular shape in a side view without an engagement hole (rectangular lower portion F2) Is formed stepwise, and then, in the final step, the preliminary engagement portion of the intermediate molded body is punched out in a square shape from the side in the lateral direction. The engagement hole 3a is formed, and the engagement portion 3 having a quadrangular shape in a side view is formed.

具体的には、先ず、図5(イ),(ロ)に示すように所定長さの断面小判形又は丸形状のブランクAを第1工程で据え込み加工を行って、図6(イ),(ロ)に示すように前面と後面の下部が先細まり状の第1成形体Bを形成する。なお、ブランクAとしては、予め所定の長さに切断しておいたものを圧造工程に順次供給して用いる他、例えば第1工程の前段側に、供給装置によって供給される断面小判形の棒状素材を所定長さに切断する切断工程を設け、この切断工程により切断されたブランクAを圧造工程に供給して用いるようにしてもよい。  Specifically, first, as shown in FIGS. 5 (a) and 5 (b), a blank A having a predetermined cross-sectional oval or round shape is upset in the first step, and FIG. 6 (a). , (B), the first molded body B is formed such that the lower portion of the front surface and the rear surface is tapered. In addition, as blank A, what is cut in advance to a predetermined length is sequentially supplied to the forging process and used, for example, a bar having a cross-sectional oval shape supplied by a supply device on the front side of the first process. A cutting step for cutting the material into a predetermined length may be provided, and the blank A cut by this cutting step may be supplied to the forging step and used.

次に、図7(イ),(ロ)に示すように第2工程で第1成形体Bを圧造加工して、肉厚上部C1と中間傾斜部C2と肉薄の方形状下部C1とからなる第2成形体Cを形成する。  Next, as shown in FIGS. 7 (a) and 7 (b), the first molded body B is forged in the second step, and comprises a thick upper portion C1, an intermediate inclined portion C2, and a thin rectangular lower portion C1. A second molded body C is formed.

その後、図8(イ),(ロ)に示すように第3工程で第2成形体Cを圧造加工して円形頭部D1と方形状下部D2とからなる第3成形体Dを形成する。  Thereafter, as shown in FIGS. 8A and 8B, the second molded body C is forged in the third step to form a third molded body D composed of a circular head D1 and a rectangular lower part D2.

さらに、図10(イ),(ロ)に示すように第5工程で第4成形体Eにおける方形状の頭部E1の左右の対角線上の両端部に打ち抜き加工を施して、頭部F1に固定ボルト用の貫通孔F3,F3をもち、かつ頭部F1から下方に延びる方形状下部F2を一体に備えた第5成形体(中間成形体)Fを形成する。  Further, as shown in FIGS. 10 (a) and 10 (b), punching is performed on the left and right diagonal ends of the rectangular head E1 in the fourth molded body E in the fifth step, and the head F1 is formed. A fifth molded body (intermediate molded body) F having through holes F3 and F3 for fixing bolts and integrally including a rectangular lower portion F2 extending downward from the head F1 is formed.

その後、図11(イ),(ロ)に示すように最終工程で第5成形体Fを90度反転させ、いままでとは圧造方向を変更したうえで方形状下部F2をその側面方向から中心部分を方形状に打ち抜いて四角形状の係合孔3aを形成する。これにより、図11(ロ)及び図1〜4に示すように一方の対角線上の両端部に固定ボルト用の貫通孔2a,2aを有する方形状の取付座部2と、取付座部2の他方の対角線上の中央部から前方に突出し、かつ、四角形状の打ち抜き係合孔3aをもつ側面視形状が四角枠状の係合部3とを一体に連設してなるストライカー1を形成することができる。  After that, as shown in FIGS. 11 (a) and 11 (b), the fifth molded body F is inverted by 90 degrees in the final step, and after changing the forging direction, the rectangular lower portion F2 is centered from the side surface direction. A rectangular engagement hole 3a is formed by punching out the portion into a square shape. Accordingly, as shown in FIG. 11 (b) and FIGS. 1 to 4, the rectangular mounting seat 2 having through holes 2a and 2a for fixing bolts at both diagonal ends, and the mounting seat 2 A striker 1 is formed by projecting forward from a central portion on the other diagonal line and integrally engaging with an engagement portion 3 having a quadrangular punching engagement hole 3a and a quadrangular frame shape in side view. be able to.

なお、ストライカー1における係合部3の係合孔3aを打ち抜き作業は、上記した実施の形態のように多段式圧造成形機の最終工程で一連に行うのが好ましいが、その他、例えば多段式圧造成形機で第5成形体Fまでを成形し、その後、後工程で別のプレス機により係合孔3aの打ち抜き作業を行うようにしてもよいことは勿論である。  The punching operation of the engagement hole 3a of the engagement portion 3 in the striker 1 is preferably performed in series in the final process of the multistage forging machine as in the above-described embodiment. Of course, it is possible to mold up to the fifth molded body F with a molding machine, and then perform the punching operation of the engagement hole 3a with another press machine in a subsequent process.

以上のように構成するストライカーの製造方法によれば、取付座部2と側面視形状が四角枠状の係合部3とからなるストライカー1を、1個のブランクから多段式圧造成形機による一貫した圧造作業もしくはその圧造作業に別のプレス機による打ち抜き加工を加えるだけで一体に形成でき、これにより、従来の加熱カシメ加工を不要にして取付座部2と係合部3との連結部分の強度を強固に、かつバラツキなく成形することができる。その上、量産が容易でコスト安価に製造できると共に、設備の小型化を図ることができ、さらに、製造にあたっての部品管理も容易にできる。  According to the striker manufacturing method configured as described above, the striker 1 including the mounting seat portion 2 and the engagement portion 3 having a square frame shape in a side view can be integrated from a single blank by a multistage forging machine. Can be formed integrally by simply punching with a separate press to the forging operation, thereby eliminating the need for the conventional heat caulking process. It can be formed with strong strength and no variation. In addition, mass production is easy and can be manufactured at low cost, and the equipment can be downsized, and parts management in manufacturing can be facilitated.
